Abstract
A clutch drive (10) includes a spindle (16) mounting a driving member (94) and a driven member (126) for rotation about the spindle (16). The driving member (94) includes a pressure plate (96) which moves axially along the spindle (16) to engage and disengage from the driven member (122). Disengagement of the pressure plate (96) is effected by a piston and cylinder mechanism (34, 52) operated by compressed air. A plurality of circumferentially spaced springs (106) yieldably urge the pressure plate (96) into engagement with the driven member (126). A drive link (112) interconnects adjacent springs (106) to form a link through which driving torques are transmitted. The drive link (112) is curved, so that shock loads created upon engagement of the clutch are absorbed by straightening the drive link (112).
