Abstract
A driving force transmitting clutch device includes a main shaft; a first rotor rotatable around the main shaft; a second rotor rotatable around the main shaft; an inner sleeve member attached to the second rotor for engaging the first rotor, and being movable in an axial direction of the main shaft; an outer sleeve member for receiving the inner sleeve member therein; and a coil spring for urging the inner sleeve member in a direction that the inner sleeve member engages the first rotor and the outer sleeve. When a movement of the outer sleeve is stopped, the outer sleeve moves the inner sleeve for releasing the inner sleeve from the first rotor and for releasing the inner sleeve from the outer sleeve.
Claims7
A driving force transmitting clutch device for transmitting a driving force, comprising:
- a main shaft;
- a first rotor rotatable around the main shaft;
- a second rotor rotatable around the main shaft;
- an inner sleeve member disposed between the first and second rotors to be able to transmit a rotational force therebetween, and assembled with the second rotor to be movable in an axial direction of the main shaft;
- an outer sleeve member disposed between the first and second rotors, and receiving the inner sleeve member therein;
- a braking device for stopping the outer sleeve member;
- and
- a coil spring situated between and attached to the inner sleeve member and the outer sleeve member for urging the inner sleeve member toward the first rotor so that when the outer sleeve is stopped by the braking device, the outer sleeve moves the inner sleeve toward the second rotor for releasing the inner sleeve from the first rotor.
