Title: Friction member, disk assembly and torque converter
Inventor: TAKASHIMA HIROSHI
IPC: F16H45/00
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To restrain a pressure drop in fluid caused by rotation by providing plural grooves having a bending part in the middle by penetrating at least one of surfaces opposed in the shaft direction to the outer peripheral end from the inner peripheral end. SOLUTION: Plural grooves 90 having a bending part in the middle by penetrating to the outer peripheral end from the inner peripheral end are formed on an annular friction surface. The bending part of the grooves 90 bends so as to become a V shape opening in the rotational direction R1 of a friction facing, and includes an outer peripheral groove 90a and an inner peripheral groove 90b. A hydraulic fluid flowing in the vicinity of the friction facing flows toward the radial directional inside R2 in the outer peripheral groove 90a and toward the radial directional outside R3 in the inner peripheral groove 90b. Since these flows collide with each other in a central part of the grooves 90, a flow along the grooves 90 of the annular friction surface of the friction facing is not caused to thereby restrain an oil pressure drop in the fluid between the friction facing and a drive plate.
