ABSTRACT:
An apparatus which can effect relative movements between first and second parts that are rotatable relative to each other between several positions utilizes a helix having a stack of convolutions and being non-rotatably associated with one of the parts, a follower (such as a pin or an eccentric or an annulus of rolling elements) which is arranged to extend between at least two convolutions of the helix and is affixed to the other part, an electric or fluid-operated or other suitable motor which serves to rotate at least one of the parts relative to the other part, a further part (such as the release bearing for a clutch in the power train of a motor vehicle) which is movable axially with and relative to the first part, and a coupling device serving to separably connect the further part to the first part except in at least one selected position of the second part relative to the first part. Such arrangement facilitates convenient separation of the clutch from the means for operating the release bearing.
