DUAL CLUTCH TRANSMISSION FOR MOTOR VEHICLES

摘要

A dual clutch transmission for motor vehicles includes first and second input shafts, two clutches selectively coupling the input shafts to the engine, two intermediate shafts arranged parallel to the input shafts, gearwheel pairs including fixed wheels and freely rotating wheels, of which a first gearwheel is arranged on one of the input shafts and a second gearwheel is arranged on one of the intermediate shafts, coupling devices selectively coupling the freely rotating wheels to the respective shaft, and a respective output gearwheel arranged on each of the two countershafts. A large number of ratios is made possible, without enlarging the dimensions of the transmission and the weight thereof, by virtue of the fact that one output gearwheel is a freely rotating wheel selectively coupled to the intermediate shaft thereof by a coupling device.

1. A dual clutch transmission for motor vehicles, comprising:
a first input shaft and a second input shaft; two clutches configured to selectively couple the first input shaft and the second input shaft respectively to an engine; two intermediate shafts arranged parallel to the transmission input shafts; gearwheel pairs comprising fixed wheels and freely rotating wheels, of which a first gearwheel is arranged on one of the input shafts and a second gearwheel is arranged on one of the intermediate shafts; coupling devices configured to selectively couple the freely rotating wheels to the respective shafts; and two output gearwheels arranged on each of the two intermediate shafts wherein at least one of the output gearwheels is a freely rotating wheel selectively coupled to the respective intermediate shaft by a coupling device.
