Conical disk pair for a belt-driven conical-pulley transmission

摘要

A sensing device integrated into a conical disk pair includes a sensing piston that is axially movable relative to the input shaft over a radially stepped guide surface that is formed on a shaft on which the sensing device is carried, and a corresponding opposing stepped surface formed on the sensing piston. The steps define a damping chamber between the guide surface and the opposing surface, whose volume changes when the sensing piston moves axially relative to the shaft.
