Abstract

A clutch release bearing assembly includes a tubular plastic carrier member for actuating a self-aligning clutch release bearing. The bearing is connected to the carrier with a rigid annular clip. The rigid clip is formed with recesses or tabs which receive or engage complimentary mating portions provided on the carrier. A radial flange is formed on the clip for axially restraining the bearing on the carrier. Bearing seals may be provided on the flange to prevent debris from entering the bearing assembly.

Claims

1. A rigid cylindrical bearing and carrier assembly, comprising:

bearing means (1);

a bearing carrier (3) for actuating said bearing means (1);

said bearing carrier having a radially outwardly extending thrust flange intermediate the axial ends of said carrier;

clip means (9) having an axially extending tubular portion (16) disposed radially of said bearing means (1) for connecting said bearing means (1) to said carrier (3);

said clip means (9) comprising first engagement means (19,59,61) for engaging said carrier (3) and locking said clip means and bearing means to said carrier and second engagement means (11) for axially restraining said bearing means, said second engagement means (11) comprising a radially projecting rigid member highly resistant to axial deflection encapsulating said bearing means between said rigid member and said thrust flange, said radially projecting rigid member providing means to preload said bearing means against said thrust flange, and

at least a portion of said axially extending tubular portion (16) of said clip means being axially and radially nested on an axial end portion of said carrier and in intimate contact therewith to thereby provide radial strength and rigidity to that portion of said carrier.

2. The assembly of claim 1 wherein said carrier means (3) comprises a plastic material and wherein said clip means (9) comprises a metallic material.

3. The assembly of claim 1 wherein said carrier means (3) comprises resilient means (21) for cooperating with said first engagement means (19,59).

4. The assembly of claim 3 wherein said resilient means (21) comprises hook means (23) and wherein said first engagement means comprises at least one recess (19) formed in said clip means for receiving said hook means (23).

5. The assembly of claim 1, wherein said clip means (9) comprises resilient means (61) for engaging said carrier.

6. The assembly of claim 1 wherein said second engagement means (11) comprises an annular flange (11).

7. The assembly of claim 6 further comprising seal means (39) provided on said second engagement means.

8. The assembly of claim 7 wherein said seal means (39) comprises means (40) for sealing said bearing means (1).

9. The assembly of claim 7 wherein said seal means (39) comprises means (49) for sealing lubricant within said bearing carrier (3).
