Title:
FRICTION CLUTCH
Document Type and Number:
WIPO Patent Application WO/2019/159461
Kind Code:
A1
Abstract:
Provided is a friction clutch which is compact and has a large transmission torque capacity, with which a shock during engagement is small, and with which a drag torque is not readily generated.
In a friction clutch 10, if a piston 32 is activated with a low hydraulic pressure, a pusher plate 16, a friction plate 26, and a driven plate 18 are caused to frictionally engage, and an elastic body 20 is compressed, and therefore shock during engagement is small. If the piston 32 is activated with a high hydraulic pressure, an input cone 15 and an output cone 24 frictionally engage, and therefore the transmission torque capacity can be increased, and the number of friction plates 26 and driven plates 18 can be reduced, thereby making the friction clutch compact. When the hydraulic pressure is released, the elastic body 20 that was compressed acts to separate the input cone 15 and the output cone 24, and therefore the input cone 15 and the output cone 24 can be prevented from becoming stuck, and the generation of drag torque can be suppressed.
