Definitions

  • Lifting device for an assembly of a motor vehicle as well as a method for fixing at least one support arm of a lifting device
  • the invention relates to a lifting device for an assembly of a motor vehicle with the features of the preamble of claim 1. Furthermore, the invention relates to a method for fixing at least one support arm of a lifting device with the features of independent claim 9.
  • Lifting devices are largely used in workshops for motor vehicles to assemble or dismantle heavy assemblies, such as drive devices.
  • the lifting devices usually have a load receiving unit for receiving the assembly, as well as a support unit that can be arranged on a lifting unit.
  • the load bearing unit is positioned by moving or adjusting the support arms relative to the construction group of the motor vehicle.
  • a lifting device for an assembly of a motor vehicle is already known from DE 102014 117 703 A1.
  • the lifting device has a load-bearing unit with at least one support arm.
  • a coupling unit for releasable connec tion of the support arm to the assembly of a motor vehicle is arranged on the support arm.
  • a lifting device for a motor vehicle assembly is also shown in EP 3 336633 A1.
  • the motor vehicle assembly has a load-bearing unit with at least one support arm pivotable about a longitudinal axis of the load-bearing unit and a coupling unit arranged on the support arm for releasably connecting the support arm to the motor vehicle assembly.
  • a blocking unit is shown, which makes it possible to secure the set position of the support arm, ie the position of the support arm that is pivoted with respect to the load-bearing unit.
  • the blocking unit has a brake body which is adjustable by means of an actuating element, in particular a tensioning lever, in the direction of a housing base body of the load receiving unit.
  • the lifting device according to the invention makes it possible to realize any angular adjustment of the support arms.
  • the lever clamp has at least two spring-loaded pins on the side facing the central disk, which pins can disappear into a recess against a spring force. In this way, the fixation takes place through a frictional connection that takes place a multiple of the spring force and thus with a higher force than if only two smooth or roughened surfaces were pressed against each other by the lever clamp.
  • the arrangement of the bores on the outer edge of the central disk is advantageous, since this enables a smaller and more cost-effective design of the lever clamp.
  • the lifting device can be adapted as flexibly and easily as possible to different structural groups of a vehicle, it has a coupling unit or a receiving unit which is arranged longitudinally displaceably on the support arm and is designed for detachable connection of the support arm to the assembly of a motor vehicle.
  • a particular advantage is that, depending on the angular position, when fixing the at least one support arm, at least one spring-loaded pin and one hole in the central disk also form a positive fit by engaging a fixed pin in a hole.
  • the fixation is improved by the form fit, which acts in addition to the force fit.
  • Figure 1 is a perspective view of a lifting device with a load receiving unit with four support arms
  • Figure 2 shows an enlarged section of a central disk with a support arm
  • wel cher shows the fixation of the support arm in the closed state
  • Figure 3 shows an enlarged section of a central disk with a support arm
  • wel cher shows the fixation of the support arm in the open state
  • Figure 1 shows a perspective view of a lifting device 1 with a load receiving unit 2 and a support unit 4, which can be attached to a lifting unit, for example.
  • the load-bearing unit 2 is used to connect to a component of a motor vehicle and for this reason has at least one support arm 3.
  • FIG. 1 An exemplary embodiment with four support arms 3 is shown in FIG. 1, the four support arms 3 being rotatable about a central axis 10.
  • the support arms 3 can have at least one coupling unit 9 or at least one receiving unit 9, which are arranged on the support arm 3 in a longitudinally displaceable manner and for the detachable connection of the support arm 3 with the assembly of the motor vehicle are formed.
  • the support arms 3 are connected to a lever clamp 30 so that an edge 12 of the central disk 11 is located between the lower edge of the central disk 11 and the lever clamp 30.
  • the support arm 3 can be fixed on the central disk 11 so that the support arm 3 can no longer be moved, or it can be released again so that the support arm can be rotated about the central axis 10.
  • Figure 2 shows an enlarged section of a central disk 11 with a support arm 3, which shows the fixation of the support arm 3 in the closed state.
  • the lever clamp 30 is taken on the central disk 11 facing end of the support arm 3 fasten.
  • An edge 12 of the central disk 11, which is designed as a guide edge, is enclosed both by the support arm 3 and by the lever clamp 30.
  • a Fi xing of the support arm 3 takes place by the screw 13, which is located in a Ge thread, is tightened.
  • the fixation of the support arm 3 is loosened by opening the screw 13, which is located in the thread.
  • the lever clamp 30 has at least two spring-loaded pins 32 on the side facing the central disk 11.
  • the spring-loaded pins 32 are spring-loaded and can be completely sunk into a recess of the lever clamp 30 against a spring force.
  • the recess has a diameter that corresponds to the outer diameter of the spring-loaded pins 32.
  • the spring loaded pins 32 can have a circular cross-section and have a rounded tip at the top.
  • the central disk 11 can have bores 33.
  • a corresponding central disk 11 with bores 33 is shown in FIG.
  • the bores 33 are arranged on the underside of the central disk 11, that is to say on the side facing the support unit 4.
  • the bores 33 are arranged in such a way that they can enter into a form fit with the spring-loaded pins 32 when the support arm 3 assumes an angular position so that the bore 33 and the attached pin 32 are opposite one another.
  • the bores 33 have an inner diameter which corresponds to the outer diameter of the spring-loaded pins 32.
  • the bores 33 are arranged at the same distance from the central axis 10 as the spring-loaded pins 32.
  • the bores 33 are usually arranged on the outer edge of the central disk 11, so that the spring-loaded pins 32 can enter into a form fit with the bores 33.
  • the bores 33 are arranged at an even distance along the outer edge of the central disk 11.
  • seventy-two bores 33 are arranged on the central disk 11 in a uniformly distributed manner.
  • the center point of each borehole 33, starting from the central axis 10, has an angle of 5 ° to the next borehole 33.
  • Each bore 33 has a diameter of 5 mm and a depth of 4.5 mm.
  • 6 spring-loaded pins 32 are arranged on each of the lever clamp 30, the center of a circular pin 32 having an angle of 5.2 ° from the central axis 10 to the center of the next pin 32.
  • the lever clamp 30 has six spring-loaded pins 32.
  • the support arm 3 is fixed with a pure frictional connection (the angular position is selected so that the bores 33 and the pins 32 are not opposite one another) by placing the six spring-loaded pins 32 against the wall of the central disk 11 be pressed. Since each of the spring-loaded pins 32 is loaded with a spring force, there is a frictional connection between the support arm 3 and the central disk 11, which corresponds to at least six times the spring force. In addition to the force from the springs, there is also a frictional connection due to the surface friction between the further points of contact between the support arm 3 with the lever clamp 30 and the central disk 11.
  • the support arm 3 is fixed by a form fit and a force fit.
  • the remaining five spring-loaded pins 32 are pressed against the wall of the central disk 11. Since each of the spring-loaded pins 32 is loaded with a spring force, there is a frictional connection between the support arm 3 and the central disk 11, which corresponds to at least five times the spring force. In addition to the force from the springs, there is also a frictional connection due to the surface friction between the further points of contact between the support arm 3 with the lever clamp 30 and the central disk 11.
