Abstract

A pneumatic clutch actuator includes an actuator housing, a piston assembly, a bearing carrier, and a locking element. The piston assembly is disposed within the actuator housing and is movable between a first position and a second position. The piston assembly has a piston head, an elongate member extending from the piston head, and a lock ring coupled to the elongate member. The bearing carrier supports a bearing and is slidably disposed on a portion of the actuator housing. The locking element is operatively connected to the piston assembly and engages the bearing carrier to adjust a total length of the piston assembly as the piston assembly moves from the second position towards the first position to compensate for wear of the clutch assembly.
