Taper disk-continuously variable transmission for use in drive train of motor vehicle, has sensor chamber connected with pressure discharging chamber over control edge of sensor and channel that is formed between shaft and sensor piston

摘要

The transmission (1) has a taper disk pair enclosed by a clasping unit and provided with taper disks, where one of the disks is arranged in a pressing chamber in an axially displaceable manner based on a pressure medium under pressure. A torque sensor (9) has a torque sensor piston (15) that limits a torque sensor chamber (19). The sensor chamber is connected with a pressure discharging chamber (31) over a control edge (23) of the sensor and a pressure discharging channel (25) having axial grooves (29), where the channel is formed between a shaft (3) and the sensor piston.
