Abstract

A friction plate is provided. The friction plate includes a core plate including a plurality of cutouts extending axially therethrough; a plurality of friction material segments, each of the segments being received in one of the cutouts; and at least one connector affixing the frictional material segments in place in the cutouts to form a mechanical connection between the friction material segments and the core plate. A method of forming a friction plate for a clutch is also provided. The method includes attaching a plurality of friction material segments to a core plate including a plurality of cutouts extending axially therethrough by inserting each of the friction material segments into one of the cutouts and affixing the friction material segments in place with at least one connector to form a mechanical connection between the friction material segments and the core plate.

First claim

What is claimed is:

1. A friction plate for a clutch comprising:
a core plate including a plurality of cutouts extending axially therethrough;
a plurality of distinct and separate friction material segments, each of the segments being received in one of the cutouts; and
at least one connector affixing the frictional material segments in place in the cutouts to form a mechanical connection between the friction material segments and the core plate.

2. The friction plate as recited in claim 1 wherein the core plate is a metal ring.

3. The friction plate as recited in claim 1 wherein the at least one connector is a plurality of staples.

4. The friction plate as recited in claim 3 wherein each of the staples includes a head, a radially inner leg and a radially outer leg, each of the staple heads extending circumferentially and radially from the radially inner leg to the radially outer leg.

5. The friction plate as recited in claim 1 wherein the core plate includes a radially inner ring, a radially outer ring and a plurality of legs extending radially from the radially inner ring to the radially outer ring, the radially inner ring, a radially outer ring and the legs defining the cutouts.

6. The friction plate as recited in claim 5 wherein the at least one connector is a plurality of connectors, each of the connectors extends circumferentially across one of the legs.

7. The friction plate as recited in claim 6 wherein each of the connectors pierces two adjacent friction material segments of the friction material segments.

8. The friction plate as recited in claim 5 wherein each of the legs are located between two adjacent cutouts of the cutouts.

9. The friction plate as recited in claim 5 wherein the core plate includes an axial surface, each of the legs including a recessed groove receiving a head of one of the connectors, the heads being flush with the axial surface.

10. The friction plate as recited in claim 5 wherein the at least one connector is a plurality of connectors, each of the friction material segments being axially held in place by at least one of the connectors radially held in place by the respective cutout in which the friction material segment is received.

11. A method of forming a friction plate for a clutch comprising:
attaching a plurality of distinct and separate friction material segments to a core plate including a plurality of cutouts extending axially therethrough by inserting each of the friction material segments into one of the cutouts and affixing the friction material segments in place with at least one connector to form a mechanical connection between the friction material segments and the core plate.

12. The method as recited in claim 11 wherein the at least one connector is a plurality of staples.

13. The method as recited in claim 11 wherein the at least one connector is plurality of connectors, the affixing of the friction material segments in place including piercing each of the friction material segments with at least one of the connectors.

14. The method as recited in claim 13 wherein the piercing each of the friction material segments with at least one of the connectors includes piercing each of the friction material segments with two of the connectors.

15. The method as recited in claim 13 wherein each of the connectors pierces two of the frictional material segments.

16. A friction plate for a clutch comprising:
a core plate including a plurality of cutouts extending axially therethrough;
a plurality of friction material segments, each of the segments being received in one of the cutouts; and
a plurality of staples affixing the frictional material segments in place in the cutouts to form a mechanical connection between the friction material segments and the core plate.

17. The friction plate as recited in claim 16 wherein each of the staples includes a head, a radially inner leg and a radially outer leg, each of the staple heads extending circumferentially and radially from the radially inner leg to the radially outer leg.

18. The friction plate as recited in claim 16 wherein the core plate includes a radially inner ring, a radially outer ring and a plurality of legs extending radially from the radially inner ring to the radially outer ring, the radially inner ring, a radially outer ring and the legs defining the cutouts.

19. The friction plate as recited in claim 18 wherein each of the staples extends circumferentially across one of the legs.

20. The friction plate as recited in claim 19 wherein each of the staples pierces two adjacent friction material segments of the friction material segments.
