<p>PCT No. PCT/FI86/00036 Sec. 371 Date Nov. 28, 1986 Sec. 102(e) Date Nov. 28, 1986 PCT Filed Apr. 2, 1986 PCT Pub. No. WO86/06332 PCT Pub. Date Nov. 6, 1986.The present invention relates to a semiautomatic transmission for vehicles, construction machines or similar equipment. In one embodiment of the invention, the semiautomatic transmission comprises a synchro-mesh transmission which has an electrically controlled gear shift mechanism, an electric control unit, for controlling the gear shift mechanism, and sensors, for measuring the torque of the engine, the rotating speed of the output shaft of the transmission and the driving speed. The sensors are arranged to transmit corresponding to measured quantities to the electric control unit for selecting a gear suiting the actual driving situation. Between the output shaft, of the transmission and the drive shaft, with which the power is transmitted to the drive gear, there is, in accordance with the invention, a bidirectionally engaging overrunning clutch to connect shaft, with each other. The engaging circuit of the transmission is an electric power circuit that is opened and closed by the accelerator pedal of the engine or with a similar power regulator.</p> |
