Clutch disengaging device

摘要

A friction clutch having a tiltable clutch spring can be disengaged by tilting the spring with a bearing which can be moved axially to engage the tips of radially inwardly extending prongs of the spring. The bearing is movable axially by an actuator which, in turn, is movable axially and away from a support by a system of ramps and rolling elements. The ramps or the rolling elements are caused to move radially of the axis of the bearing in order to move the rolling elements or the ramps axially in a direction to cause a tilting of the spring and hence a disengagement of the clutch.
