Description

centrifugal pendulum

The invention relates to a centrifugal pendulum with a rotatably mounted about an axis of rotation pendulum mass carrier and distributed over the circumference of this pendulum masses suspended along pendulum tracks in the centrifugal force field of the rotating pendulum mass support pendulum masses, wherein the pendulum masses are accommodated on the pendulum mass carrier by means of pendulum bearings consisting of radially superimposed and axially arranged in the same plane arranged trajectories of the pendulum masses and the pendulum mass carrier and in each case a rolling on this rolling pendulum role, the pendulum masses of a arranged in the plane of the pendulum mass carrier in recesses arranged middle part and two arranged on the sides of the pendulum mass carrier, the pendulum mass carrier radially overlapping side parts are formed.

Centrifugal pendulum are known in particular from drive trains of motor vehicles and serve the speed-adaptive vibration damping of torsional vibrations in particular of torsional vibration-sensitive internal combustion engines. For this purpose, the centrifugal pendulum on a about an axis of rotation, for example, the crankshaft of the engine rotatably arranged pendulum mass carrier, distributed over the circumference pendulum masses are arranged in the centrifugal force field of the rotationally driven pendulum mass carrier along a predetermined pendulum track and along this pendulum track are displaced. Occurring torsional vibrations are redeemed by shifting the pendulum masses along the pendulum tracks against the centrifugal force. In addition to further embodiments of centrifugal pendulum pendulum masses, for example, from DE 10 2013 214 829 A1 discloses a centrifugal pendulum, in which the pendulum masses are formed from a central part and two narrow side parts flanking the pendulum mass carrier. Two pendulum bearings spaced apart in the circumferential direction between the pendulum masses and the pendulum mass support are provided for the pendulum displacement of the pendulum masses, in which raceways of the pendulum mass and the pendulum mass support are arranged axially at the same height and radially one above the other, on each of which a pendulum roller rolls , Here, the central part forms the track of the pendulum masses and is received within recesses of the pendulum mass carrier, wherein the recesses are formed so that the pendulum masses along the predetermined pendulum track can perform the maximum swing angle. For axial support of the pendulum masses and to increase the mass of the pendulum masses, the narrow side parts overlap the pendulum mass carrier.

The object of the invention is the development of a centrifugal pendulum in particular for further reduction of the axial space.

The object is solved by the subject matter of claim 1. The dependent of the claim 1 claims give advantageous embodiments of the subject matter of claim 1 again.

The proposed centrifugal pendulum serves the torsional vibration isolation, in particular in a drive train of a motor vehicle in particular for torsional vibration isolation of a torsionally vibrating internal combustion engine. The centrifugal pendulum contains a pendulum mass carrier rotatably mounted about a rotation axis. The pendulum mass carrier can be connected directly to the crankshaft or in another drive train device, for example in a one-mass flywheel, a torsional vibration damper such as a dual mass flywheel, a friction clutch or its clutch disc to be integrated in a hydrodynamic torque converter or in a dual clutch. The pendulum mass carrier can fulfill other functions in addition to the inclusion of pendulum masses. For example, the pendulum mass carrier can form an input-side or output-side loading part of a torsional vibration damper, an output part such as a hub part of a drive train device or the like. The pendulum masses, which are distributed on the pendulum mass carrier for the purpose of eliminating torsional vibrations distributed over the circumference, are suspended in this way along pendulum tracks in the centrifugal force field. This means that the pendulum masses are displaceable over a predetermined oscillation angle and are accelerated radially outward in the centrifugal force field of the pendulum mass carrier rotating about the axis of rotation and are displaced, inter alia, depending on registered torsional vibrations along the given pendulum track against the effect of centrifugal force to a smaller radius and thus have a wiping effect on the torsional vibrations. As a result, a speed-adaptive torsional vibration damper is formed, which is tuned, for example, to a predetermined order of vibration of the internal combustion engine.

The pendulum masses are added to the pendulum mass carrier by means of pendulum bearings, which are formed from radially superimposed and axially arranged on the same plane raceways of the pendulum masses and the pendulum mass carrier and in each case a rolling on this pendulum role. In this case, two circumferentially spaced pendulum bearings can be arranged, so that the pendulum masses follow a pendulum motion, which follow a bifilar suspended pendulum, wherein a pendulum motion is predetermined by the shape of the raceways and a parallel or trapezoidal arrangement of the pendulum threads can correspond. Furthermore, it can be provided that the pendulum movement can be circular on a radius or over the swing angle on several radii or in free form. Furthermore, a self-rotation of the pendulum masses may be provided during a pendulum motion by the formation of the raceways.

The pendulum masses are constructed of several disc parts such as sheet metal parts and connected to each other. Furthermore, the side parts radially outside the pendulum mass carrier can be integrally connected to each other, for example, in one piece, with an additional connection is provided radially inward. A middle part is connected to the side parts, which is accommodated in recesses in the axial plane of the pendulum mass carrier and contains the pendulum mass-side raceways. The recesses are dimensioned so that a displacement of the middle part in the intended swing angle of the pendulum is undisturbed possible. In this case, the pendulum mass carrier can have the middle part radially overlapping regions which contain the raceways associated with the pendulum mass carrier, against which the middle part and thus the pendulum masses are supported radially against the centrifugal force with the interposition of the pendulum roller. With the middle part a narrow, that is provided with less material thickness side part is provided on both sides, which radially overlaps the sides of the pendulum mass carrier, so that the pendulum masses are guided on the pendulum mass carrier. Spacers may be provided between side parts and pendulum mass carriers, which in particular reduce the friction between the side part and pendulum mass carrier. The spacers can be formed from plastic parts, coatings and / or embossings of the side parts and / or the pendulum mass carrier received on the side parts and / or on the pendulum carrier. In particular, to limit the axial space of the pendulum masses to a level of the outer surfaces of the two side parts, middle part and side parts are connected to each other within an axial space of the side parts. This means that the predetermined by the side parts component is not extended by connecting means. Rather, the connecting means or the properties of the connection are formed so that they are provided within the opposite sides of the side parts.

According to an advantageous embodiment, the middle part and the side part can be connected by riveting the side parts and the middle part, the side parts having depressions in the region of the setting and closing heads of a rivet and axial impressions being provided on the middle part in the region of the depressions are. Here, the depressions dip into the indentations of the central part and are applied to the embossments, so that the setting heads and closing heads of the riveting of the side parts with the middle parts forming rivets is maximally flat with the outer side surface of the side parts and the space given by the side parts space remains.

In a further advantageous embodiment, at least one side part can have axially expanded connecting means, for example projections, for example tubular rivets, rivets, flared pins or tongues or the like, such as slots of the middle part. For example, may be issued from the side panels, for example, rectangular tongues, for example, pass through the rectangular openings formed in the middle part and placed on the opposite side to the middle part. The tongues of both side parts can pass through the central part through one or several openings. Two tongues can pass through one opening per opening and on the other side te of the central part in different directions, for example, radially inward and radially outwardly folded. The tongues of both side parts can be introduced into one another while forming a compression in an opening. In openings, one or more tongues of one or both side parts can engage at a distance, wherein a bolt is pressed into the distance, so that the tongues are braced against the middle part. For example, one or more tongues of both side parts can only partially be introduced into an opening under axial contact or compliance with an axial clearance and be pressed by means of a bolt with the central part.

As an alternative to the formation of tongues, hollow rivet pots can be embossed on the side parts, which pass through circular openings and are riveted to the middle parts at their end sides, the opposite side parts being excluded in the rivet area. Before riveting, the side parts can be fixed by means of corresponding openings of tabs as described above. In a further advantageous embodiment, the side parts and the middle part can be riveted together, wherein the side parts have depressions in the region of the setting and closing heads of a rivet. Here, the rivet may have a central contact area between setting and closing head, which is radially expanded and is pressed radially in an opening of the central part. The central contact region can have a collar outer contour and a radially inner collar contour, wherein the collar outer contour can be narrower, wider or equal to the inner contour of the collar of the contact region.

By axial compression of the rivet on the one hand the side parts are pressed axially against the central part and the collar outer contour against the inner circumference of the opening of the central part. In this case, the collar outer contour can be deformed in such a way that it becomes In addition, from the inside against the side parts is pressed, that is, the gap between

Fills side parts and middle part in the area of the depressions.

The connections of the side parts with the central part by means of the provided tabs or rivets or the like can be done on a single or more diameters and distances in the circumferential direction, for example radially superimposed or diagonally.
