Abstract
A clutch release mechanism shortened in its axial length. The clutch release mechanism is applied to a friction clutch 5 engaged to transmit a torque between a rotary output member 4 and a rotary input member 2, 11. A hydraulic actuator 26 generates a hydraulic pressure to reduce a pushing force applied to the friction clutch. A plurality of elastic members 27 are arranged annularly around a rotational center axis while keeping predetermined intervals. An oil passage 33 is communicated with the hydraulic actuator 26 while passing through the interval.
Claims6
A release mechanism for a friction clutch that is constantly pushed in an axial direction to be engaged to transmit a torque between a rotary output member and a rotary input member, comprising:
- a hydraulic actuator that is adapted to establish a hydraulic pressure in the axial direction in a manner such that a pushing force applied to the friction clutch is reduced;
- a plurality of elastic members arranged annularly around a rotational center axis in a manner to establish an elastic force in the axial direction;
- a predetermined interval maintained between the adjacent elastic members;
- and
- an oil passage communicated with the hydraulic actuator while passing through the interval.
