<p>A clutch drive (10) comprising a spindle (16) on which are rotatably mounted a driving member (94) and a driven member (118), said driving member including itself a pressure plate (96) movable axially along the spindle (16) to engage and disengage from the driven member (118), the engagement of these elements being caused by resilient means (108) while their disengagement is effected by a piston (52) operated by compressed air, and the movable pressure plate (96) carrying a bearing (68) the inner race (66) of which is spaced apart from the spindle (16) and piston (52) radially but held in axial abutting engagement with the latter.</p><p>In order to prevent the inner race (66) of the bearing (68) from unwanted rotation, a coil spring mechanism (74) is interposed between a notch (82) cut in the spindle and a further notch (84) formed in a collar (86) which is press-fitted into said bearing inner race (66).</p><p>For use particularly as fan clutch drive for a vehicle engine.</p> |
