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

A starting clutch includes a planetary mechanism; a first clutch for outputting a torque to an outer diameter portion of the planetary mechanism; a second clutch for outputting the torque to an intermediate portion of the planetary mechanism; and a lock mechanism for locking a reactive force from an inner diameter portion of the planetary mechanism.

Starting clutch and method of controlling the same

The present invention provides a starting clutch in which an input side element and an output side element are joined together by applying an axial load thereby to transmit a power, which clutch comprises an urging device for always providing the axial load, and a releasing device for releasing the input side element and the output side element from the axial load.

Starting clutch and method for controlling same

The present invention provides a method for manufacturing friction plates obtained by adhering friction members to substantially annular core plates, comprising the steps of simultaneously stamping a plurality of coaxial core plates having different diameters with a joint portion remaining therebetween, preliminarily adhering friction member segments to the stamped plural core plates, and stamping the joint portion during or after a main adhering step following the preliminarily adhering step.

Method for manufacturing friction plate

An end-bearing equipped one-way clutch includes an outer and inner rotary members, torque-transmitting members arranged between the first and second rotary members, retainers maintaining the torque-transmitting members with equal angular intervals and having radially-extending annular flanges at one axial end portions thereof, and end bearings arranged respectively along both axial ends of the retainers maintaining the first and second rotary members in a concentric relation. One of the end bearings, which is arranged on the side opposite to the flanges, is composed of a first cylindrical portion fit in the outer rotary member, a second cylindrical portion fit on the inner rotary member and a toroidal plate portion connecting the first and second cylindrical portions to each other. A reinforcement member is formed at each of the first and second cylindrical portions so as to improve the rigidity against each load to be applied in the radial direction to the end bearing provided on the side opposite to the flanges.
