Further embodiments are set out in the appended dependent claims

• - wenigstens ein Befestigungselement zum Befestigen des Lagerelements an einer Halterung, und
• - wenigstens ein elastisches Element, in dem wenigstens eine Aufnahmeöffnung zur Aufnahme eines Befestigungsmittels ausgebildet ist,

wobei das wenigstens eine elastische Element an einem vorbestimmten Befestigungsbereich des wenigstens einen Befestigungselements angebracht ist, wobei sich das wenigstens eine elastische Element ausgehend von dem vorbestimmten Befestigungsbereich in Richtung der wenigstens einen Aufnahmeöffnung erstreckt, und wobei der vorbestimmte Befestigungsbereich und die wenigstens eine Aufnahmeöffnung zumindest in axialer Richtung des Befestigungselements um einen vorbestimmten axialen Versatz zueinander versetzt angeordnet sind.The elastic bearing element according to the invention comprises:

• - at least one fastening element for fastening the bearing element to a holder, and
• - at least one elastic element, in which at least one receiving opening is designed to receive a fastener,

wherein the at least one elastic element is attached to a predetermined fastening region of the at least one fastening element, wherein the at least one elastic element extends from the predetermined fastening region in the direction of the at least one receiving opening, and wherein the predetermined fastening region and the at least one receiving opening extend at least in the axial direction Direction of the fastening element are arranged offset from one another by a predetermined axial offset.

The fastening region of the elastic element on the fastening element and the receiving opening formed in the elastic element are arranged offset from one another in the axial direction by a predetermined axial offset. The elastic element extends axially from the fastening area to a receiving section in which the receiving opening is formed. The receiving opening can be cylindrical. The attachment to the fastening element and the design of the elastic element provide a predetermined deflection of the receiving opening in the elastic element relative to the fastening element. When the elastic bearing element is used, a fastener for an exhaust system is received in the receiving opening.

The vibrations and shocks that occur during operation of a vehicle move the exhaust system and the bolt in the receiving opening. Due to the movement of the bolt in the receiving opening, the receiving opening or the elastic element is deflected relative to the fastening element. The elastic element can compensate or absorb the vibrations and shocks, thereby preventing the vibrations from being transmitted to the vehicle frame and the vehicle body. The elastic element designed in this way does not require any stiffening elements or the like in the area of the receiving opening, which must be completely embedded in the elastic material of the elastic element. The strength or rigidity provided by the spring element, particularly in the area of the receiving opening, is sufficient to be able to attach and hold a fastening element of an exhaust system on the bearing element.

The fastening element can be tubular or socket-shaped in cross section. The fastening element can be designed to be accommodated in a holder. The fastening element can be pushed or plugged into a holder, for example. The fastening element can be made of plastic or a similar material. The fastening element can also be conical or spherical. The outer peripheral surface of the fastening element can expand conically. The inner circumferential surface of the fastening element can also expand conically. It is also conceivable that the outer peripheral surface and the inner peripheral surface expand conically and the fastening element has a conical shape overall.

The fastening element can be connected to the elastic element by vulcanization. In the fastening area, the elastic element can be connected flatly to the fastening element. In the fastening area, the elastic element can run out in the direction of the axial end of the fastening element. In other words, the thickness of the material of the elastic member on the inner peripheral surface of the fastener may decrease toward the axial end of the fastener. With such an outlet, the stresses occurring in the elastic element can be distributed and thus stress peaks in an area of the elastic element can be avoided.

The fastening area can be provided at an end portion of the fastening element. For example, the fastening region can extend radially into the fastening element by a predetermined distance starting from an end edge of the fastening element, for example like a collar. The fastening element and the elastic element can be designed such that the fastening element can limit the deflection of the elastic element and in particular the deflection of the receiving section with the receiving opening relative to the fastening element. The fastening element can thus serve as a stop for the elastic element or to limit the deflection of the elastic element in the event of large deflections of the exhaust system. For example, the elastic element can be accommodated in the fastening element. The fastening element can essentially completely surround the elastic element, i.e. extend radially outside around the elastic element. An end section of the receiving opening or the receiving section can protrude from the fastening element in the axial direction. In the axial direction, there can be no overlap between the axial extent of the fastening area and the axial extent of the receiving opening. The fastening area can also be arranged centrally in the fastening element.

The at least one elastic element can be designed such that the central axis of the receiving opening and the longitudinal axis of the fastening element are offset in the radial direction and extend parallel to one another. However, the elastic element can also be designed such that the receiving opening and the fastening element are arranged coaxially. The elastic element can be designed at least in sections in the form of a truncated cone or in the form of an oblique truncated cone. The frustoconical section can be followed by a tubular section which forms the end section of the receiving section. Starting from the fastening area, an opening can extend through the elastic element, which merges into the receiving opening or into the receiving opening ends. The receiving opening can be cylindrical in order to be able to accommodate a fastener of an exhaust system. The receiving opening can be provided with at least one stop or at least one stop surface. A fastener to be received in the receiving opening can rest on the stop surface. With the stop surface, sliding of the fastener in the receiving opening in the axial direction can be avoided. The fastening means can be, for example, a fastening bolt or a fastening pipe of an exhaust system of a vehicle. A lance-like positioning projection can also be arranged on the elastic element.

The elastic element has a section extending in the radial direction. A notch can be formed on the end surface of the radial section of the elastic element facing away from the receiving opening. The notch may extend along the inner peripheral surface of the fastener at a predetermined radial distance from the inner peripheral surface. The axial extent of the section extending in the radial direction essentially corresponds to the axial extent of the fastening area. The fastening area may be formed by a predetermined portion of the inner peripheral surface of the fastener.

The elastic element can extend from the radial section along the longitudinal axis of the fastening element in the direction of the receiving opening. Starting from the fastening area, the elastic element can initially extend radially and, following the radial section, essentially axially in the direction of the receiving opening. At the transition of the radial section into the essentially axially extending section, a recess forming an undercut or an undercut can be provided in the elastic element.

The fastener may have a first end portion and a second end portion. The fastening region for the elastic element may be arranged in the second end portion of the fastening element and the receiving opening may be arranged in the first end portion of the fastening element. The end portions are provided at opposite ends of the fastener.

The fastening element can essentially completely surround the elastic element. It is possible that a portion of the receiving opening formed in the elastic element protrudes from the fastening element. For example, a section of the receiving opening provided with a chamfer can protrude from the fastening element.

The elastic element can extend from the fastening area on the inner peripheral surface of the fastening element with a radial distance along the inner peripheral surface. The radial distance can increase starting from the fastening area in the direction of the receiving opening and vary in the circumferential direction of the fastening element. This can be due in particular to the asymmetrical design of the elastic element.

At least one projection projecting radially inwards can be formed on the fastening area. The radially inwardly projecting projection may be provided on the inner peripheral surface of the fastening member. A plurality of radially inwardly projecting projections can also be provided on the inner circumferential surface of the fastening element. The projection or projections serve to support the attachment of the elastic element to the attachment portion of the fastener. In particular, the radial projection can serve to axially secure the attachment of the elastic element to the fastening element.

The fastening area can be formed by at least one shoulder on the inner peripheral surface of the fastening element. The axial extent of the shoulder can correspond to the axial extent of the radial section of the elastic element. The shoulder projects radially inwardly from the inner peripheral surface. The shoulder can be used to emboss the elastic material in the vulcanization tool.

A socket can be accommodated in the receiving opening formed in the elastic element. The bushing can be essentially tubular, conical or spherical. The bushing can be a sliding bushing. The bushing can accordingly form a plain bearing for a fastening means of an exhaust system to be accommodated in the bushing or the receiving opening. The inner peripheral surface of the bushing may be free of the elastic material used for the elastic member. At least one radial projection can be formed on the socket. The projection may project radially outwardly from the outer peripheral surface of the bushing. The projection can be arranged in a central area of the socket. The projection serves to support the bushing on the elastic element. Several projections can also be provided on the socket. The projections can be offset from one another by a predetermined angle and can be different from the Extend away outer peripheral surface of the socket. Instead of the radial projection or projections, circumferential recesses or several recesses can also be formed on the bushing.

At least one stop element can be formed on the elastic element. The stop element can extend towards the inner peripheral surface of the fastening element. The elastic element can be supported on the fastening element via the stop element. The stop element can be arranged in a ring shape around the receiving opening and protrude in the radial direction. A plurality of stop elements can also be provided, each of which is arranged offset from one another by a predetermined angle about the central axis of the receiving opening. In this case, the stop elements can be designed as circular ring segments. Furthermore, a stop element projecting in the direction of the elastic element can be formed on the inner peripheral surface of the fastening element. The stop element can extend continuously along the inner peripheral surface of the fastening element. The stop element can be formed from an elastic material. In this case too, several stop elements can be provided on the inner circumferential surface of the fastening element. Regardless of whether the stop elements are formed on the elastic element or the fastening element, the stop elements serve to limit the deflection of the elastic element relative to the fastening element in a damped manner.

To position the fastening element on a holder, the fastening element can have at least one stop element and/or a curvature or bulge on its outer peripheral surface. The section of the fastening element between the stop element and the curvature, i.e. the cylindrical section of the fastening element, can be received in the holder. The stop element serves in particular to ensure that the bearing element or the fastening element can be attached to the holder in its predetermined position. The curvature, on the other hand, can serve to fix the bearing element in its predetermined position on the holder. The stop element can be in the form of one or more radial projections or a circumferential flange with a circular or irregularly shaped profile.

The receiving opening and the fastening element can be arranged coaxially. In this case, the elastic bearing element can be designed symmetrically or rotationally symmetrical.

The inner peripheral surface of the fastener may be covered with a layer of elastic material. The layer of elastic material can extend from the fastening area along the inner peripheral surface of the fastener. The layer of elastic material can also be thickened in places to form a stop element.

The fastening element can be essentially socket-shaped or tubular. The fastening element can be essentially cylindrical. At least at one end of the fastening element, a section can extend radially inwards. The elastic element can be attached to the fastening area on this radial section. Furthermore, the fastening area can be provided on the radial section of the fastening element, via which the elastic element can be fastened to the fastening element. The radial section can form an opening which adjoins the opening extending through the elastic element. The radial section can be provided at the end of the fastening element opposite the end with the receiving opening. Accordingly, the elements used for the bearing element can be essentially tubular, bush-shaped or cylindrical. The fastening element and also the bushing, which can be provided in the receiving opening, can each only be provided with the elastic material of the elastic element on one of their peripheral surfaces. It is also conceivable that both peripheral surfaces of the fastening element and/or the bushing are provided at least in sections with the elastic material of the elastic element.

The shape of the elastic element, which is designed as described above, can also enable no stiffening elements or structural elements to be provided in the receiving opening or in the receiving section. The elastic element can be designed to be free of stiffening elements or structural elements in the area of the receiving opening or in the receiving section. In particular, no stiffening elements or structural elements in the receiving section are embedded in the elastic material of the elastic element. This applies in particular to stiffening elements or structural elements made of a material other than the elastic material used for the elastic element. The socket, which can be accommodated in the receiving opening, is used solely to store a fastener for the exhaust system. For this purpose, this bushing can be designed as a plain bearing.

The fastening element can have a radial section on which the fastening area is provided. Starting from the fastening area provided on a radial section, the elastic element can extend in the direction of the receiving opening. The radial section can extend essentially perpendicularly or obliquely to the central axis of the fastening element. The fastening region can be formed by at least a section of a surface on the radial section of the fastening element. The surface on which the fastening area is provided can extend essentially perpendicularly or obliquely to the central axis of the fastening element. The fastening area and an end face of a receiving section of the elastic element which has the receiving opening can be arranged offset from one another by a predetermined axial offset.

• - at least one elastic element, in which at least one receiving opening is designed to receive a fastener,

wherein the at least one elastic element is attached to a predetermined fastening region of the at least one fastening element, the at least one elastic element extending from the predetermined fastening region in the direction of a receiving section having the at least one receiving opening, the receiving section having an end face, the end face of the receiving section is arranged offset by a predetermined axial offset from the fastening area.

The predetermined axial offset can be adjusted between an end face of the receiving section of the elastic element which has the receiving opening and a radial section of the fastening element which has the fastening region. The predetermined axial offset can be adjusted between a surface on the radial section which has the fastening region and the end face of the receiving section which has the receiving opening.

Connecting elements which are designed to establish a connection with a holder or a similar component can be provided on the fastening element. A similar component in this context can be, for example, a cable guide. Such a cable guide can be used to guide a cable in a vehicle or a building. In a vehicle, a cable guide can be attached to a section of the body or vehicle frame via the elastic bearing element. The connecting elements can be designed in the form of locking projections. The locking projections can extend in the axial direction of the elastic bearing element. The locking projections can have locking lugs. The locking lugs can extend outwards in the radial direction. The locking projections can be formed on the fastening element so as to be offset from one another. In particular, the locking projections can be arranged offset from one another in the circumferential direction of the elastic bearing element. Stop elements can be provided between the locking projections, which can rest on a holder or a similar component. This allows the elastic bearing element to assume a predetermined position on the holder or similar component.

The receiving opening can have at least one coupling element which extends from the inner circumferential surface of the receiving opening in the radial direction and is designed to couple the elastic bearing element to a fastening means. The fastening means can in particular be a bolt-shaped fastening means such as a threaded bolt. The at least one coupling element on the inner circumferential surface of the receiving opening can be designed, for example, in the form of a web, a bead, a bulge, a lip or a locking lug. The coupling elements on the inner peripheral surface of the receiving opening can be formed in one piece with the elastic element. In this case, the coupling elements can be formed in the form of circumferential bulges on the inner peripheral surface of the receiving opening. Several bulges can be provided on the inner circumferential surface of the receiving opening. The at least one coupling element serves to simplify the attachment of the elastic bearing element to a fastener. The elastic bearing element is coupled to the fastening means by the coupling elements. This means that the fitter has both hands free to finally fix the elastic bearing element on the fastening means or to connect the elastic bearing element to another component before the final fixation.

The at least one coupling element thus enables pre-fixation to the fastener means to simplify assembly.

As already mentioned, a socket can be provided in the receiving opening. The at least one coupling element can be arranged on the inner peripheral surface of the socket. The coupling elements can be formed by webs on the inner circumferential surface of the socket. The webs can be made of an elastic material. The webs can be formed in one piece with the socket.

The webs can be provided offset from one another in the circumferential direction of the socket on the inner circumferential surface of the socket. The coupling elements can also be formed by latching elements. The locking elements can be provided together with the webs on the inner peripheral surface of the socket. In this case, the webs and the locking elements can be arranged alternately on the socket in the circumferential direction. The locking elements can be locking projections that extend in the axial direction and/or radial direction. The locking projections can have locking lugs projecting radially inwards at their end.

The present invention further relates to a holder for an elastic bearing element, which has an elastic bearing element according to the type described above. The holder can be used in particular to fasten the elastic bearing element to a vehicle.

The elastic bearing element can be connected to the holder via a press connection. However, other types of connection for connecting the elastic bearing element to the holder are also conceivable.

1 shows a perspective view of a bearing element according to a first embodiment of the invention, which is generally designated 10.

The bearing element 10 has a fastening element 12 and an elastic element 14. The elastic element 14 is arranged and received in the socket-shaped fastening element 12. The fastening element 12 has a first end section 16 and a second end section 18. On the outer surface of the first end section 16, a curvature or a bead 20 can be seen, which is used to fasten the bearing element 10 to a holder (not shown) for attaching the bearing element 10 to a vehicle (not shown). The bead 20 can also be used to lock within the holder.

The fastening region BB, on which the elastic element 14 is connected to the fastening element 12, is formed in the second end section 18. A stop element 22 is provided at the second end section 18 of the fastening element 12. With the stop element 22 It can be ensured that the bearing element 10 is fastened or fixed in its predetermined position on the holder (not shown). For example, the bracket for attaching the bearing member 10 to a vehicle may accommodate the portion of the fastener 12 that extends between the stop member 22 and the bulge 20. On the inner peripheral surface 24 of the fastening element 12 in the second end section 18, the elastic element 14 is attached in the fastening area BB. The fastening area BB is formed by a portion of the inner peripheral surface 24 of the fastening element 12. An opening 26 extends through the elastic element 14 and extends into a receiving opening (see 2 ) transforms. The receiving opening is used to receive a fastener for the exhaust system of a vehicle.

2 shows another perspective view of the bearing element 10. 3 shows a front view of the bearing element 10. In 3 the bearing element 10 is viewed from the direction of the first end section 16. 4 shows a sectional view along sectional view IV-IV in 3 .

A receiving section 28 of the elastic element 14 is arranged radially within the first end section 16. In the receiving section 28, the receiving opening 30 is formed, which serves to receive a fastener of the exhaust system of a vehicle. The receiving opening 30 is cylindrical. An end section 28 ₁ ( 4 ) of the receiving section 28 is tubular. At the transition of the end face 28 ₂ of the receiving section 28 into the receiving opening 30, a chamfer or a conical section 32 is formed. The receiving section 28 or its outer peripheral surface is spaced from the inner peripheral surface 24 of the fastening element 12 in the radial direction. The end face 28 ₂ of the receiving section 28 is spaced from the fastening area BB by a predetermined axial offset AV _SB .

The inner peripheral surface 24 of the fastener 12 is covered with a thin layer 36 of elastic material. The thin layer 36 can be made of the same material as the elastic element 14. Starting from the first end section 16, a free space 34 extends between the layer 36 of elastic material on the inner peripheral surface 24 of the fastening element 12 and the elastic element 14 in the direction of the second end section 18.

The curvature or the bead 20 is formed all around on the outer peripheral surface 38 of the fastening element 12. The stop member 22 corresponds to a projection extending along a predetermined portion of the outer peripheral surface 36.

The elastic element 14 is arranged in the socket-shaped fastening element 12 and fastened to the fastening element 12. Starting from the second end section 18, in which the elastic element 14 is attached to the inner peripheral surface 24 of the fastening element 12, a free space 34 surrounds the elastic element 14. The free space 34 is in the radial direction from the layer 36 of elastic material on the inner peripheral surface 24 and the outer surface of the elastic element 14 limited. The elastic element 14 is designed such that the central axis M _AD of the receiving opening 30 is offset from the central axis M _B of the fastening element 12 by a predetermined offset V. The offset V between the central axis M _AD of the receiving opening 30 and the central axis M _B of the fastening element 12 is a radial offset. The two central axes M _AD and M _B thus extend offset by the predetermined offset V in the radial direction but parallel to one another.

The elastic element 14 has a radial section 40, via which it is connected to the inner peripheral surface 24 of the fastening element 12 in the second end section 18. Starting from this radial section 40, the elastic element 14 extends with a substantially conical section 42 up to the tubular end section 28 ₁ of the receiving section 28.

The elastic element 14 is connected in the fastening area BB with its section 40 extending in the radial direction to the inner peripheral surface 24 of the socket-shaped fastening element 12 in the second end section 18. The fastening area BB extends from the axial end surface of the fastening element 12 over a predetermined distance along the inner peripheral surface 24 of the fastening element 12. The axial extent of the fastening area BB essentially corresponds to the axial extent of the radial section 40 of the elastic element 14. The fastening area BB and the receiving opening 30 are arranged offset from one another in the direction of the central axis M _B of the fastening element 12 by the axial offset AV. The axial extent of the fastening area BB and the axial extent of the cylindrical receiving opening 30 do not overlap one another. The receiving opening 30 is provided radially inward of the first end section 16 of the fastening element 12. Between the radial section 40 and the tubular end section 28 ₁ of the receiving section 28, the elastic element 14 extends substantially in shape in its section 42 of a crooked truncated cone. The opening 26 in the elastic element 14 extends from the axial end side of the fastening element 12 in the form of an oblique truncated cone through the elastic element 14 until it merges into the cylindrical receiving opening 30. The central axis M _AD of the receiving opening 30 and the central axis M _B of the fastening element 12 run parallel to one another with a radial offset V. In addition to the axial offset AV between the receiving opening 30 and the fastening area BB, there is a radial offset between the central axes M _B and M _AD .

Between the thin layer 36 of the elastic material on the inner peripheral surface 24 of the fastening element 12 and the outer surface of the elastic element 14, a clearance 34 extends up to the radial section 40 of the elastic element 14 in the second end section 18. Due to the shape of the elastic element 14 The free space 34 surrounding the elastic element 14 in sections also does not have a rotationally symmetrical shape. In addition to the offset V, this is also clear from the fact that in the section view 4 the distance between the inner peripheral surface 24 and the wall of the receiving opening 30 in the area below the central axis M _B of the fastening element 12 is greater than the distance between the wall of the receiving opening 30 and the inner peripheral surface 24 in the area above the central axis M _B of the fastening element 12. At the end of the free space 34 in the axial direction or at the transition of the frusto-conical section 42 into the radial section 40 of the elastic element 14, a recess 44 with a rounded cross-section is formed, which surrounds the frusto-conical section 42 in the radial direction. The recess 44 forms an undercut in the elastic element 14. The recess 44 supports the deflectability of the elastic element 14 relative to the fastening element 12.

The tubular end portion 28 ₁ of the receiving portion 28 protrudes a predetermined distance in the axial direction beyond the axial end surface of the end portion 16 of the fastening element 12. The end face 28 ₂ of the end section 28 extends parallel to the axial end surface of the end section 16. The transition edge between the phase 32 and the cylindrical receiving opening 30 extends in the sectional view 4 essentially congruent with the axial end edge of the end section 16.
