Title:
FRICTION CLUTCH
Document Type and Number:
WIPO Patent Application WO/2019/187319
Kind Code:
A1
Abstract:
Provided is a friction clutch which is compact, has a large capacity of transmission torque, and is less likely to generate a transmission torque. Since a friction clutch 10 transmits torque between a clutch drum 12 and a hub 16 by frictional engagement between the tapered surfaces of a pusher plate 20 and an end plate 22 and the tapered surfaces of an output cone 24, the capacity of transmission torque is large and the friction clutch 10 can be made relatively compact. When the clutch is released, hydraulic oil is supplied to a canceller chamber 34 to close a valve mechanism 40, the hydraulic oil is collected in the canceller chamber 34, and the hydraulic pressure thereof pushes a piston 18 and the pusher plate 20 connected thereto, so that a drag torque is less likely to be generated.
