Abstract
In a torque coupling having an input flange, an input shaft, an actuator, and a multiple clutch pack, and a driving mechanism, the present invention broadly comprises an actuator for transferring the input toque to the output shaft. The actuator comprises an actuator plate which is limited to only rotational movement, a pressure plate which is limited to only axial movement, and a plurality of actuator pins. The driving mechanism rotates the actuator plate through a gear set and forces the actuator pins to move vertically. The vertical movement of the actuator pins forces the pressure plate in an axial direction. In a torque coupling, the actuator is used to transfer the input torque to the output shaft through compression of the multiple clutch pack by the actuator.
