Title:
CONTROL METHOD FOR REVERSE INPUT PREVENTION CLUTCH
Document Type and Number:
WIPO Patent Application WO/2017/145934
Kind Code:
A1
Abstract:
In the present invention, during rotary positioning of an output-side member, from the start of energization of a motor that applies input torque to a reverse input prevention clutch to the end of positioning, an electromagnetic clutch of a lock release retaining means is energized and an unlocked state is retained so that, during the rotary positioning operation, even if reverse input torque is applied at the same time and in the same direction as input torque, the transmission of rotation can be accomplished smoothly without an output shaft relocking. When rotary positioning has been completed, energization of the motor is interrupted after energization of the electromagnetic clutch is interrupted and a locked state is restored, and as a result, the rotary position of the output-side member is not altered by reverse input torque.
