ABSTRACT:
A traction-type clutch bearing device includes an engaging piece (1) maintained in permanent contact with the clutch diaphragm (13) by an elastic member (14), a thrust bearing (2) which can move axially relative to a guide tube (10) under the action of a control member (11), and an axial connecting device interacting with a retaining groove made either in the engaging piece or in a member of the thrust bearing to connect and/or disconnect the thrust bearing and the engaging piece. The connecting device includes a ball cage (3) and a plurality of balls (23) mounted between the engaging piece (1) and the thrust bearing (2) and which are capable, in the connection position, of interacting with a wedging zone (25) and the a retaining groove (24), to ensure axial locking, and, during removal, with a release zone (30). The wedging zone (25) and the release zone (30) are located either on an inner raceway (6) of the thrust bearing (2) or on the engaging piece (1).
