CLUTCH UNIT

摘要

A clutch unit includes a lever-side clutch section provided on an input side, for controlling rotational torque to be input through lever operation, and a brake-side clutch section provided on an output side, for transmitting the rotational torque from the lever-side clutch section to the output side, and interrupting rotational torque to be reversely input from the output side. The brake-side clutch section has a two-layer structure, in which two one-way clutches are arranged side by side in an axial direction. The first one-way clutch interrupts rotational torque in a forward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions, whereas the second one-way clutch interrupts rotational torque in a backward direction, which is reversely input from the output side, through meshing of serrated projection and depression portions arranged in an opposite direction.

1. A clutch unit, comprising:
an input-side clutch section provided on an input side, for controlling transmission and interruption of a rotational torque to be input; and an output-side clutch section provided on an output side, for transmitting the rotational torque from the input-side clutch section to the output side, and interrupting a rotational torque to be reversely input from the output side, the output-side clutch section comprising:
an input member to which the rotational torque is to be input;a stationary member restricted in rotation;an output member from which the rotational torque is to be output;an engagement element arranged between the stationary member and the output member, for interrupting the rotational torque from the output member through engagement between the stationary member and the output member, and transmitting the rotational torque from the input member through disengagement between the stationary member and the output member; andcontrol means for engaging, at the time of interrupting the rotational torque, the engagement element between the stationary member and the output member through meshing of projection and depression portions, and disengaging, at the time of transmitting the rotational torque, the engagement element between the stationary member and the output member through unmeshing of the projection and depression portions.
