SLIDING MATERIAL AND BELT FOR WET-TYPE CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To reduce power loss by increasing friction coefficient (μ) at a contact surface between belt and pulley and reducing pulley nip pressure, while retaining wear resistance.

SOLUTION: The sliding material is used for a wet-type continuously variable transmission, and contains a resin serving as a matrix and mesophase pitch carbon fibers. The content of the mesophase pitch carbon fibers is defined as 1 vol.% to≤60 vol.%.
