Abstract

A drive assembly for a motor vehicle clutch is provided. The drive assembly includes a subassembly includes at least one clutch facing and at least one support segment supporting the at least one clutch facing, the at least one support segment including an outer radial portion fixed to the at least one clutch facing and an inner radial portion extending radially inward from the outer radial portion; an extender connected to the inner radial portion of the at least one support segment; and a cover plate, the extender connecting the subassembly to the cover plate. A method of forming a drive assembly and a method of forming a plurality of drive assemblies are also provided.

First claim

What is claimed is:

1. A drive assembly for a motor vehicle clutch comprising:
a subassembly including at least one clutch facing and at least one support segment supporting the at least one clutch facing, the at least one support segment including an outer radial portion fixed to the at least one clutch facing and an inner radial portion extending radially inward from the outer radial portion;
an extender connected to the inner radial portion of the at least one support segment;
a cover plate, the extender connecting the subassembly to the cover plate, the extender being a distinct piece from the cover plate, the extender being fixed to the cover plate by first fasteners; and
springs supported by the cover plate, an inner radial edge of the extender being radially outside of the springs.

2. The drive assembly as recited in claim 1 wherein the at least one support segment is a plurality of support segments, each of the support segment being riveted to the extender.

3. The drive assembly as recited in claim 2 wherein the inner radial edge of the extender is radially inward further than an inner radial edge of the at least one support segment.

4. The drive assembly as recited in claim 3 wherein the extender is an extension ring having an inner circumference forming the inner radial edge, the inner circumference being radially inward further than the inner radial edges of the support segments.

5. The drive assembly as recited in claim 1 further comprising a second cover plate fixed to the cover plate, the cover plate and the second cover plate supporting the springs axially therebetween.

6. The drive assembly as recited in claim 5 further comprising a drive flange axially between the cover plate and the second cover plate, the cover plate and the second cover plate configured for driving the drive flange via the springs.

7. The drive assembly as recited in claim 1 wherein the at least one clutch facing is two clutch facings, the at least one support segment being sandwiched axially between the two clutch facings.

8. The drive assembly as recited in claim 1 wherein the first fasteners are rivets.

9. The drive assembly as recited in claim 8 wherein the rivets are extruded rivets.

10. The drive assembly as recited in claim 1 wherein the extender is fixed in alignment with the outer circumference of the cover plate by the first fasteners.

11. The drive assembly as recited in claim 1 wherein the first fasteners pass through at least two holes to connect the at least one support segment to the extender.

12. The drive assembly as recited in claim 1 wherein the extender axially contacts the cover plate.

13. The drive assembly as recited in claim 1 wherein an outer circumference of the cover plate is radially outward from the inner radial edge of the extender.

14. A method of forming a drive assembly comprising:
fixing a plurality of support segments to at least one clutch facing;
fixing radially inner portions of the support segments to an extender; and
fixing the extender to a damper cover plate, the extender being a distinct piece from the damper cover plate, the extender being fixed to the cover plate by first fasteners, the damper cover plate supporting springs, an inner radial edge of the extender being radially outside of the springs.

15. The method as recited in claim 14 wherein the fixing the radially inner portion of the support segments to the extender includes riveting the radially inner portion of the support segments to the extender.

16. The method as recited in claim 14 wherein the extender is an extension ring having an inner circumference forming the inner radial edge of the extender, the radially inner portions of the support segments being fixed to the extender such that the inner circumference is radially inward further than inner radial edges of the support segments.

17. A method of forming a plurality of drive assemblies comprising:
providing a set of subassemblies of a same configuration, each of the subassemblies including at least one clutch facing and at least one support segment supporting the at least one clutch facing, the at least one support segment including an outer radial portion fixed to the at least one clutch facing and an inner radial portion extending radially inward from the outer radial portion;
fixing each subassembly of a first subset of the subassemblies to one of plurality of first cover plates, each of the subassemblies of the first subset being fixed to the respective first cover plate via a respective extender; and
fixing each subassembly of a second subset of the subassemblies to one of plurality of second cover plates, the second cover plates having a design different than the first cover plates.

18. The method as recited in claim 17 wherein the each of the subassemblies of the second subset are fixed directly to the respective second cover plate.

19. The method as recited in claim 17 wherein the first cover plates have a first diameter and the second cover plate have a second diameter, the second diameter being greater than the first diameter.

20. The method as recited in claim 17 wherein each of the subassemblies of the second subset are fixed to the respective second cover plate via a respective second extender, the first extenders each having a first inner diameter, the second extenders each having a second inner diameter, the second inner diameter being different than the first inner diameter.
