Abstract
A fluid pressure operated friction clutch actuating system for releasing the clutch includes a pressure operator, an actuator mechanism, which mechanism is shown as including a housing having a pair of telescopic pistons acting on a force transmission member and reacting through the actuator housing on an end wall of the clutch housing. The force transmission member has a U-shaped recess through which the clutch output shaft and the bearing retainer pass so that the force transmission member is in force transmitting engagement with the clutch throw out bearing while the system is in its operative position in the clutch housing. The actuator pistons act on the force transmission member when pressurized to move the throw out bearing to release the friction clutch through its belleville spring. The actuator housing and the force transmission member may be removed from the clutch housing through a clutch housing access opening by clamping them together to fully retract the pistons, moving them laterally so that the bearing retainer and clutch output shaft are no longer within the U-shaped opening, and then moving them laterally out through the access opening. When the fluid system is a…
