Abstract
The present invention provides a starting clutch in which an input side element and an output side element are joined together by applying an axial load thereby to transmit a power, which clutch comprises an urging device for always providing the axial load, and a releasing device for releasing the input side element and the output side element from the axial load.
Claims48
A starting clutch, comprising:
- an input side element and an output side element which are engaged with each other by applying an axial load, thereby to transmit power;
- a damper;
- urging means for permanently providing the axial load to said input side element and said output side element;
- and
- releasing means for releasing said input side element and said output side element from the axial load to release the engagement of said input side element and said output side element.

A method for controlling a starting clutch having input and output side elements, which are engaged with each other to transmit power, said method comprising:
- maintaining said input and output side elements in an engaged state without supplying hydraulic pressure;
- and
- releasing said input and output side elements from the engaged state by supplying hydraulic pressure.
A method for controlling a starting clutch having input and output side elements, which are engaged with each other to transmit power, and further having a damper, said method comprising:
- maintaining said input and output side elements in an engaged state without supplying hydraulic pressure;
- and releasing said input and output side elements from the engaged state by supplying hydraulic pressure.
A starting clutch, comprising:
- an input side element and an output side element which are engaged with each other by applying an axial load, thereby to transmit power;
- urging means for permanently providing the axial load to said input side element and said output side element;
- and
- releasing means for releasing said input side element and said output side element from the axial load to release the engagement of said input side element and said output side element;
- wherein a fixed member is disposed on an outer periphery of an output shaft, and a driven rotary member is disposed on an outer periphery of said fixed member;
- wherein said input side element is a separator plate of a multi-plate clutch, said output side element is a friction plate of said multi-plate clutch, and a clutch case of said multi-plate clutch is provided on said driven rotary member;
- and
- wherein said urging means includes a spring disposed between said clutch case and a piston of said releasing means, said piston being operated in a direction along which said piston is separated from said input side element and said output side element.
