Abstract
The gearbox includes two input transmission shafts (7) and an output transmission shaft, and many speeds disposed on it. The input transmission shafts are connected in a detachable manner to the output shaft of the engine by closed geometric speed change clutches, and one friction clutch (4) is provided in the circulation trajectory of the torques between the control motor and the output transmission shaft.
