CLUTCH CONTROL DEVICE WITH CONTROL RELEASE BEARING

摘要

The invention concerns a device comprising a control release bearing (32) having a globally rotating about a release bearing axis (X). The release bearing (32) is provided with a support member (34), mobile substantially parallel to the release bearing axis (X), designed to co-operate with a diaphragm (30), a control member (36) mobile in rotation about the release bearing axis (X), and means (44, 46) for transforming the rotational movement of the control member (36) into a translational movement of the support member (34) including two complementary members (44, 46) in mutual screwing co-operation, respectively connected to the support and control members. A first screwing member comprises a slide (44), mobile substantially parallel to the release bearing axis (X), provided with at least two pins (52) uniformly distributed at an angle about the release bearing axis (X). Each pin (52) is mounted rotatable on the slide (44) about an axis (Y) substantially perpendicular to the stop release bearing (X), and co-operates with a helical groove (56) arranged on the second screwing member (46).
