Abstract

The invention relates to a motor vehicle clutch release bearing device including a rolling bearing that forms a member for transmitting an axial force, having a rotating ring and a non-rotating ring, between which a rolling chamber for rolling elements is defined. The rotating ring provides a first radial portion intended to come into contact with an actuating member when a sufficient axial force is applied to the non-rotating ring by a member that is able to move in translation, and a second radial portion that is intended to bear against a spring, which exerts an axial force in the opposite direction to the axial force exerted by the member that is able to move in translation, dedicated to preloading the rolling bearing in an opposite direction to the actuating member.

First claim

1 . A motor vehicle clutch release bearing device comprising:
a rolling bearing that forms a member for transmitting an axial force, having a rotating ring and a non-rotating ring, between which a rolling chamber for rolling elements is defined, wherein the rotating ring provides:
a first radial portion that is intended to come into contact with an actuating member when sufficient axial force (F 2 ) is applied to the non-rotating ring by a member ( 2 ) that is able to move in translation, and
a second radial portion that is intended to bear against a spring that exerts an axial force (F 5 ) in the opposite direction to the axial force (F 2 ) exerted by the member ( 2 ) that is able to move in translation, dedicated to preloading the rolling bearing in an opposite direction to the actuating member.

2 . The motor vehicle clutch release bearing device claim 1 , wherein the rotating ring further comprises a toroidal portion having a concave surface that forms a raceway for the rolling elements, at least one of the radial portions that are intended to come into contact with one of an actuating member and a spring extending from the raceway.

3 . The motor vehicle clutch release bearing device according to claim 2 , wherein the rotating ring further comprises an intermediate portion disposed between at least one of the radial portions that are intended to come into contact with one of an actuating member and a spring and another portion of the rotating ring, the intermediate portion making it possible to adjust the position of the rolling bearing depending on the actuating member and the spring.

4 . The motor vehicle clutch release bearing device according to claim 1 , wherein the rotating ring is a single piece.

5 . The motor vehicle clutch release bearing device according to claim 1 , wherein the rotating ring further comprises a first part including the radial part that is intended to come into contact with an actuating member, and a second part that is intended to bear against a spring, the two parts being securely fixed.

6 . The motor vehicle clutch release bearing device according to claim 5 , wherein the first part of the rotating ring further comprises retention means for the second part of the rotating ring.

7 . The motor vehicle clutch release bearing device according to claim 6 , wherein the first part of the rotating ring further comprises an axial tubular portion and the second part of the rotating ring further comprises an axial flange extending from the radial portion that is intended to bear against the spring, the axial flange being secured to the tubular portion.

8 . The motor vehicle clutch release bearing device according to claim 6 , wherein the first part of the rotating ring further comprises an edge and a boss; the second part further comprises a flange extending from the radial portion that is intended to bear against a spring, the flange having its free end housed in a space defined between the edge and the boss of the first part.

9 . The motor vehicle clutch release bearing device according to claim 6 , wherein the first part of the rotating ring further comprises a edge; the second part further comprises a flange extending from the radial portion that is intended to bear against the spring, the flange having its free end crimped around the edge of the first part.

10 . A motor vehicle equipped with a bearing, the bearing comprising:
a rolling bearing that forms a member for transmitting an axial force, having a rotating ring and a non-rotating ring, between which a rolling chamber for rolling elements is defined, wherein the rotating ring provides:
a first radial portion that is intended to come into contact with an actuating member when sufficient axial force (F 2 ) is applied to the non-rotating ring by a member ( 2 ) that is able to move in translation, and
a second radial portion that is intended to bear against a spring that exerts an axial force (F 5 ) in the opposite direction to the axial force (F 2 ) exerted by the member ( 2 ) that is able to move in translation, dedicated to preloading the rolling bearing in an opposite direction to the actuating member.
