Abstract

A clutch release bearing assembly is disclosed herein that includes a more durable and improved interface for engaging an actuator. The assembly includes a housing having at least one flange, and the housing is formed from a first material. At least one insert is supported on the at least one flange, and the at least one insert is configured to engage an actuator. The at least one insert is formed from a second material that is different than the first material.

First claim

What is claimed is:

1. A clutch release bearing assembly comprising:
a housing including at least one flange, the housing being formed from a first material; and
at least one insert supported on the at least one flange, wherein the at least one insert is configured to engage an actuator, and the at least one insert is formed from a second material that is different than the first material;
wherein the at least one flange includes a first mating element and the at least one insert includes a second mating element, wherein the first mating element and the second mating element are configured to engage with each other to connect the at least one insert with the at least one flange;
wherein the insert and the second mating element are integrally formed.

2. The assembly according to claim 1 , wherein the first mating element is an opening formed on the at least one flange, and the second mating element is a protrusion extending axially from the at least one insert.

3. The assembly according to claim 2 , wherein the opening and the protrusion are fastened to each other via a positive fit connection.

4. The assembly according to claim 2 , wherein the at least one insert is configured to be selectively removed from the at least one flange.

5. The assembly according to claim 1 , wherein the at least one flange includes a first flange and a second flange and the at least one insert includes a first insert and a second insert.

6. The assembly according to claim 1 , wherein the housing is formed from gray iron.

7. The assembly according to claim 1 , wherein the at least one insert is formed from spheroidal graphite cast iron, carbon steel, or alloy steel.

8. The assembly according to claim 1 , wherein the at least one insert is heat treated.

9. The assembly according to claim 1 , wherein the at least one flange of the housing is configured to support an anti-rotation element.

10. The assembly according to claim 1 , wherein the at least one flange has a first thickness and the at least one insert has a second thickness, and the second thickness is 50%-70% of the first thickness.

11. A method of producing a clutch release bearing assembly, the method comprising:
forming a housing from a first material, the housing including at least one flange, and forming at least one insert from a second material that is different than the first material; and
connecting the at least one insert with the at least one flange;
wherein the at least one flange includes a first mating element and the at least one insert includes a second mating element, wherein the first mating element and the second mating element are configured to engage with each other to connect the at least one insert with the at least one flange, and wherein the insert and the second mating element are integrally formed.

12. The method according to claim 11 , wherein the housing is formed from gray iron.

13. The method according to claim 11 , wherein the at least one insert is formed from spheroidal graphite cast iron, carbon steel, or alloy steel.

14. The method according to claim 11 , further comprising heat treating the at least one insert.

15. The method according to claim 11 , further comprising connecting an anti-rotation element to the at least one flange.

16. The method according to claim 11 , further comprising removing the at least one insert from the at least one flange after a predetermined period of use, and connecting at least one replacement insert to the at least one flange to replace the at least one insert.

17. The method according to claim 11 , wherein the at least one flange has a first thickness and the at least one insert has a second thickness, and the second thickness is 50%-70% of the first thickness.

18. The method according to claim 11 , further comprising engaging the at least one insert with a fork actuator.
