ABSTRACT:
An actuator for frictional engaging devices is controlled by electric signals from a control device and is disposed in a power transmission device. The actuator includes a torque generating mechanism and has at least two movably mounted frictional engaging devices having respective initial positions. The actuator includes a torque-thrust conversion mechanism which converts torque generated from the torque generating mechanism into an augmented thrust force for moving the frictional engaging devices from the respective initial positions to different positions respectively. The torque-thrust conversion mechanism has a given initial position and connecting means which transmit the augmented thrust force generated from the torque-thrust conversion mechanism to each respective one of the frictional engaging devices, whereby the torque-thrust conversion mechanism can move the frictional engaging devices from the respective initial positions to different positions respectively by rotation in one rotational direction from the given initial position.
