CLUTCH ACTUATOR WITH WEAR COMPENSATION FUNCTION

摘要

Disclosed is a clutch actuator capable of automatically compensating wear generated in a clutch pad through the medium of dependent displacement in a linear direction, and relative displacement in a linear direction on the engagement part of a spiral structure by controlling forward/backward drive with respect to a rotor of a motor. The clutch actuator comprises: a stator (12) fixed to a housing (10) of a motor; a rotor (14) installed to be rotated inside the stator (12); a first stroke member (16) screw combined with the inner circumferential surface of the rotor (14); a second stroke member (18) screw combined with the inner circumferential surface of the first stroke member (16); a stroke guiding part (20) to guide movement in the linear direction or the rotational direction of the first stroke member (16); and a rotation restricting part (24) for selectively constraining rotation of the second stroke member (18) according to the rotational direction of the rotor (14).
