Automatic transmission for controlling speed ratios between input shaft and output shaft of clutch of motor vehicle has transmission mechanism mounted on hollow shaft for air regulation to get absolute figure of number of revolutions

摘要

The automatic transmission clutch assembly (1) has transmission mechanism (4) on the hollow shaft (6), which moves the piston (11) by air pressure according to transmission oil viscosity, temperature and difference in revolutions of clutch to get an absolute figure. The transmission mechanism has resetting element (10) and sealing element (8) with which friction plate moves to regulate the output speed.
