Abstract: A wet friction material is mainly composed of a fiber base material, a filler, an friction adjusting agent and a thermosetting resin. The wet frictional material is prepared by impregnating with a liquid thermosetting resin a paper formed by mixing a paper-forming solid thermosetting resin with a fiber base material as at least a part of filler, and then applying heat to the paper so that it is hardened. The solid thermosetting resin is preferably a phenol resin. The liquid thermosetting resin is preferably made of a silicone resin represented by the following average composition formula and the amount of trifunctional unit monomers (RSiO3/2 in which R represents a substituted or unsubstituted monovalent hydrocarbon group) in monomers constituting said silicone resin is from 40 to 100 mol-%: (R1)a(OR2)bSiO(4−a−b)/2.

Abstract: In a method of producing a wet friction material according to the present invention, a water soluble material is dispersed into a raw paper including a fibrous base material, a filler, and a friction adjusting agent. Then, the raw paper is passed through water to dissolve the water soluble material to provide porosity. Thereafter, the raw paper is immersed with thermosetting resin, and heated and hardened to thereby produce a wet friction material.

Abstract: A wet multidisk friction clutch is constructed of a plurality of driving friction disks connected to an input shaft and a plurality of driven friction disks connected to an output shaft and arranged alternately with said driving friction disks, whereby power is selectively transmitted by frictional engagement between said driving friction disks and said driven friction disks. Each of said driving friction disks comprises a metal core and friction linings applied on opposite sides of said metal core and is partly cut off in a radial direction to define end portions, thereby forming a partly-open annular shape.

Abstract: In a torque converter with a lock-up mechanism which can decrease a distribution of hydraulic pressure in the radial and circumferential directions of a frictional material, which can prevent the creation of any excess reaction by the distribution of hydraulic pressure, and which can efficiently give a fastening force to the frictional material to thereby improve transmission torque capacity, an oil groove for reducing the distribution of hydraulic pressure is provided on the frictional material or a piston. This oil groove is provided for depressurization at a location which does not hinder the fastening function.

Abstract: A wet frictional plate including a made of a metal plate that is formed so as to have a plate thickness which changes to gradually increase from its outer circumferential portion toward its inner circumferential portion. Frictional materials are bonded to the surfaces of the metal plate while they are pressed and heated to make the frictional surfaces of the frictional materials parallel to each other. As a result, the density of the frictional materials increases in a direction from the outer circumferential portion of the wet frictional plate toward its inner circumferential portion.
