Abstract: Provided are a wet friction plate and a wet multiplate clutch device including the wet friction plates capable of improving the performance for discharging lubricant oil adhering to surfaces of friction members. A wet friction plate includes oil grooves and friction members on a flat plate annular core metal. At a surface of a porous layer of the friction member, a friction slide surface and lubricant oil recessed portions are formed. The lubricant oil recessed portion has no sharp portion in a pointed shape, such as a corner portion, and is formed with a smooth continuous surface. The multiple lubricant oil recessed portions depressed in a recessed shape with respect to the friction slide surface are formed. In the porous layer, hollow portions are formed to have the same formation rate between a portion forming the friction slide surface and a portion forming the lubricant oil recessed portion.

Abstract: A friction clutch assembly for an automatic transmission, a friction clutch plate, and a method of forming a friction clutch plate are provided. The method includes providing a friction material layer for a face of the friction clutch plate and cutting the friction material layer with a laser beam to form a plurality of grooves within the friction material layer. In one version, a friction plate for the friction clutch assembly includes an annular core plate having first and second opposed faces and defining an outer edge and an inner edge. Friction material is affixed to at least one of the first and second opposed faces. The friction material defines a plurality of grooves within the friction material, each groove being bordered by friction material having a ridge. The cross-section of the ridge has a corner having a radius of curvature that is less than 300 microns.

Abstract: A method for the pretreatment of a friction lining, in particular a dry clutch friction lining, comprising carbon compounds, includes modifying an effective surface of the friction lining by laser radiation in such a way that an oxidation layer containing carbon compounds is created. The pretreatment may be effected by means of laser radiation after hardening of the friction lining. The effective surface may be partially conditioned by means of laser radiation.

Abstract: A brake pad 10 can brake a rotation of a disc 200. The brake pad 10 includes a friction material 12 provided on the side of the disc 200 and a back plate 11 bonded to the friction material 12 on the opposite side of the disc 200. A thickness of a central region of the back plate 11 in a rotational direction of the disc 200 is larger than thicknesses of both end regions of the back plate 11 in the rotational direction of the disc. In the case where a minimum value of the thicknesses of the end regions of the back plate 11 is defined as “h1 [mm]” and a maximum value of the thickness of the central region of the back plate 11 is defined as “h2 [mm]”, h1 and h2 preferably satisfy a relationship of “h2−h1

Abstract: Problem—To provide a friction plate with reduced drag torque.Solution—The friction plate is formed with oil grooves having the sectorial shapes spreading toward the inner circumference and the perimeter. The adjacent edges of the friction material segments are provided with the perimeter side vertex and the inner circumference side vertex respectively. The sectorial oil groove opening toward the perimeter side from the inner circumferential side vertexes can discharge a lube oil to the perimeter side efficiently by a centrifugal force. Also, owing to the sectorial oil groove opening toward the inner circumference side from the perimeter side vertexes, a lube oil can be made to run aground onto the friction material segments due to a centrifugal force, thus, reducing the drag torque markedly compared with the conventional plates.
