Abstract
In a wet-type multi-plate clutch comprising an externally-toothed plate and an internally-toothed plate each of which is formed by adhering a friction material on a core plate and in which torque is transmitted by engaging the externally-toothed plate and the internally-toothed plate, the friction materials are adhered on opposed surfaces of the externally-toothed plate and the internally-toothed plate which are opposed to each other.
Claims10
A wet-type multi-plate clutch comprising:
- an externally-toothed plate and an internally-toothed plate, each having an axial surface including a first surface portion with a friction material thereon and an exposed friction surface portion, which is substantially coplanar with respect to said first surface portion,
- wherein torque is transmitted by engaging said externally-toothed plate with said internally-toothed plate,
- the friction material on the externally-toothed plate faces the exposed friction surface portion of the internally-toothed plate,
- the friction material on the internally-toothed plate faces the exposed friction surface portion of the externally-toothed plate, and
- a radial width of the friction material on the externally-toothed plate is greater than a radial width of the friction material on the internally-toothed plate.
