A friction plate for a wet-type multiplate clutch provided with a core plate and friction linings fixed on opposite sides of the core plate, respectively. Each of the friction linings is formed such that at a section thereof located on a side radially inner than a radial center line thereof, the friction lining has a thickness that gradually increases from an inner circumferential portion of the section toward an outer circumferential portion of the section.

Friction plate for wet-type multiplate clutch

In a lockup clutch assembly for use in a torque converter, a friction lining attached to one of a clutch piston and a front cover of the torque converter is divided into an outer-circumference-side friction lining and an inner-circumference-side friction lining. The outer-circumference-side friction lining contains as a filler diatomaceous earth in a higher proportion than the inner-circumference-side friction lining.

Lockup clutch assembly

In a double-wrap band brake assembly, an intermediate band is provided with a first friction material forming a first friction surface from a portion of the intermediate band near an apply bracket to a predetermined intermediate portion thereof, the first friction surface working for forming a lubricant film. The intermediate band is further provided with a second friction material having a thickness that is larger than a thickness of the first friction material and forming a second friction surface from the predetermined intermediate portion to a vicinity of a coupling portion of the intermediate band with a pair of outer bands, the second friction surface working for removing the lubricant film.

Double-wrap brake band assembly

A wet multiplate clutch is construction of plural friction plates and plural separator plates, which are alternately arranged. Between each two friction plates arranged adjacent to each other, plural separator plates are disposed.

Wet multiplate clutch

A double wrap brake band is provided for use with a rotating element such as a rotating drum in an automatic transmission or the like. The double wrap brake band is provided with a friction surface on an inner circumferential surface of a band portion wrapped substantially double. The friction surface is provided with an inclined part such that the friction surface becomes gradually closer to an associated outer circumferential surface of the rotating element in a rotating direction of the rotating element.
