ABSTRACT:
A planetary gear change-speed transmission for vehicles, in which a torque transmission train is operable to be drivingly connected by way of an input transmission with an input shaft, and by way of a main transmission, with an output shaft; the input transmission is operable to be shifted into direct speed ratio by a clutch and into a reduced speed ratio by braking a rotatable member by means of a brake; the main transmission includes a planetary gear reversing transmission which, by braking a rotatable member thereof, causes two other rotatable members to rotate in mutually opposite directions of rotation, whereby one of these two rotatable members is drivingly connected with the output shaft and the other of these two rotatable members is adapted to be drivingly connected, by way of a reverse speed clutch, with the torque transmission train; the rotatable member of the input transmission which can be braked, is operable to be drivingly connected with one of the two rotatable members of the reversing transmission, not in driving connection with the output shaft, while the clutch and brake of the input transmission as well as the reverse speed clutch are disengaged.
