MULTI-DISK CLUTCH FOR VEHICLE

摘要

Disclosed is a multi-disk clutch for a vehicle which is applied to a hybrid vehicle or a vehicle having a continuously variable transmission, improves the cooling performance thereof, and reduces drag torque caused by the rotation thereof. The multi-disk clutch of the present invention includes: a first clutch drum; first friction plates coupled to the first clutch drum; a second clutch drum disposed in the inner periphery of the first clutch drum and coupled to a damper absorbing vibration and shock generated in the rotating direction; second friction plates coupled to the second clutch drum and disposed between the neighboring first friction plates; a piston moving in an axial direction by means of hydraulic pressure to allow the first clutch drum and the second clutch drum to come into contact with each other, wherein the first friction plates or the second friction plates have frictional materials coupled to at least one surfaces thereof, and each frictional material having a shape of a wing having a curved portion convexedly formed on the side surface toward the rotational direction thereof and a linear portion formed on the surface opposite to the curved portion.
