Abstract
A coupling means is provided to act to apply a thrust force generated on a helical gear to a stopper for first transmission members and second transmission members to thereby suppress looseness in the stopper.
Claims17
A clutch for automobiles, comprising:
- a first transmission member mounted on a shaft to be constrained in a direction of rotation;
- a second transmission member arranged to be coaxial with the first transmission member;
- a helical gear which is arranged to be coaxial with the second transmission member and on which the second transmission member are mounted to be constrained in a direction of rotation;
- an actuator for control a state of contact between the first and second transmission members;
- and
- a stopper which restricts positions of the first and second transmission members in an axial direction, wherein:
- there is provided a transmission course which is distinguished from the first transmission and second transmission members and through which a thrust force generated on the helical gear is transmitted to the stopper.

A clutch for automobiles, comprising:
- a first transmission member mounted on a power transmission shaft to be constrained in a direction of rotation;
- a second transmission member arranged to be coaxial with the first transmission member and to generate power transmitted between the first and second transmission members;
- a helical gear arranged to be coaxial with the power transmission shaft and to be constrained relative to the second transmission member in a direction of rotation;
- operating means for controlling a contact force between the first and second transmission members to control power transmitted therebetween;
- and
- a stopper to bear the force applied by the operating means, wherein:
- the clutch further comprises a coupling means for transmitting an axial movement of the helical gear to the stopper, so that when power is transmitted between the power transmission shaft and the helical gear, a thrust force generated upon meshing of the helical gear causes the stopper to be directed toward a predetermined position.

- and
- a stopper to bear a force applied by the operating means, wherein:
- the stopper and the helical gear are formed integrally to be a unitary member, so that a thrust force generated upon meshing of the helical gear causes the helical gear itself to be directed toward a predetermined position in an axial direction whereby the stopper is caused to be directed toward a predetermined position.
