Definitions
- the invention relates to a torque transmission device having an input part and an output part, which are each connectable to a rotatable shaft and drivingly coupled via at least one intermediate element, which allows a radial displacement of the two parts.
- Such torque transmission devices in the form of clutch plates have been proposed for example by DE 10002830 A1.
- the external toothing of a component engages in the internal toothing of another component, whereby, in order to ensure a certain radial displacement possibility, there is a slight play between the interlocking toothings.
- the teeth are not uniform over the circumference. Also arises due to an eccentric rotation between the interlocking teeth by the case taking place relative movements wear on the teeth.
- the present invention has for its object to provide a torque transmission capability between two with a certain eccentricity to each other rotating components, which is robust and wear-free.
- to compensate for the eccentricity between the axes of rotation serving components should be produced in a particularly simple and cost-effective manner.
- this is achieved in a torque transmission device of the type mentioned above in that the intermediate element is coupled by means of at least two, the radial displacement enabling radially elastic regions on the one hand to the input part and on the other hand to the output part.
- the radially elastic regions may be formed by separately manufactured components, which are firmly connected on the one hand to the input part or the output part and on the other hand to the intermediate element.
- the connections required for this purpose can be designed, for example, as riveted joints and / or welded joints.
- the radially elastic regions may also be formed at least partially in one piece with the intermediate element and / or the input part and / or the output part.
- the elastic regions - viewed in the circumferential direction of the torque transmission device - are arranged at least approximately offset by 90 ° to each other about the axis of rotation of the torque transmission device.
- the areas connecting the input part and the intermediate element on the one hand and the intermediate element and the output part on the other hand can advantageously be designed or arranged symmetrically with respect to the axis of rotation of the torque transmission device.
- the elastic regions not only allow a radial displacement possibility between the input part and the output part, but also ensure a limited axial movement possibility between these two components.
- the elastic regions may each be formed at least by a circumferentially facing, bending beam-like portion.
- These sections can be designed circular arc. However, the sections can also run in the circumferential direction zigzag or wavy or sinusoidal over a certain angular range. It is expedient if the circumferential extent of the bending beam-like sections or of the elastically flexible regions is in the order of magnitude of 30 ° to 60 °.
- the at least radially elastic regions can be formed by a plurality of such, bending-kenähnliche sections, which can extend in the circumferential direction practically parallel to each other. These bending beam-like portions may be arranged adjacent in the radial direction. It may also be expedient if at least two of the adjacent, bending-beam-like sections are connected to one another, since thereby larger connection areas, for example for the production of riveted joints, arise.
- the intermediate element can be formed by at least one disk-shaped component.
- the disc-shaped component can at least two radially opposite have lying, radial sections, of which each extend in both circumferential directions are elastic areas or bending beam-like sections.
- a plurality of disk-shaped components can be axially stacked on one another. It is expedient if at least two such disk-shaped components are stacked on each other.
- a multilayer structure of the elastic regions enables a reduction of the stresses occurring in the individual material layers.
- overall a better elasticity or elastic deformability of the resilient connection between the input part and the output part ensuring elastic regions can be achieved.
- the at least one disc-like intermediate element forming the elastic regions may have an annular base body from which radial portions or arms, which carry the circumferentially extending, elastic regions, extend.
- the disc-shaped, the elastic regions forming components can be produced in a simple manner as a stamped component.

- the output part and the input part can advantageously have radially extending regions which overlap in the radial direction, but are arranged offset from one another in the circumferential direction such that end sections of the elastic regions can be connected to them.
- the torque transmission device may be formed as a clutch disc, which has a Reibbelagiki with an annular member, which extend from this component radially inwardly directed boom, where radially elastic regions are attached.
- the clutch disc may further include a hub body supporting radially outwardly directed arms to which radially resilient portions are secured.
- a designed according to the invention clutch disc can be used in a particularly advantageous manner to compensate for the axial offset between the axis of rotation of a crankshaft of an internal combustion engine and the axis of rotation of a rotatably mounted on the housing of the internal combustion engine rotor of an electric machine.
- a correspondingly mounted rotor has become known, for example, from DE 43 11 697 A1.
- the hub body of the clutch disc can be firmly connected to one end of the crankshaft and - A - the friction linings of Reibbeiaglust manners can cooperate with a clutch which is rotatably connected to the rotor of the electric machine.

For some applications, it may also be sufficient for torque transmission when the hub body 4 is pressed onto the corresponding shaft and / or shrunk.
- input part and output part used have no significance with respect to the direction of the force or torque flow that can be transmitted by means of the clutch disc 1; they merely serve to characterize the corresponding components 3 and 4.
