Abstract
A clutch drive (10) includes a spindle (16) mounting a driving member (94) and a driven member (118) for rotation about the spindle (16). The driving member (94) includes a pressure plate (96) which moves axially along the spindle to engage and disengage from the driven member (118). The pressure plate (96) is mounted on circumferentially spaced pins (102) which are slidably received in apertures (106) in the pressure plate (96). Circumferentially spaced springs (112) yieldably urge the pressure plate (96) into driving engagement with the driven member (118). A fluid pressure responsive piston (52) is connected to the pressure plate (96) by a bearing (68) and urges the pressure plate (96) away from the driven member (118). A spring (76) wraps around the spindle (16) and includes tabs (78, 80) engaging a fixed portion of the spindle and a collar (86) fixed to the bearing (68) to prevent rotation of the inner race (66) of the bearing (68) while collapsing to accommodate axial movement of the pressure plate (96).
