In a driving unit comprising an internal combustion engine 10 and a gear box 26 a torque transmitting frictional clutch 16 is provided between the output of the combustion engine and the input of the gear box. To torsional vibrations a predetermined slip is maintained between the output of the combustion engine and the input of the gear box by controlling the engagement pressure of the clutch, at least in some ranges of speed of the engine. The clutch control may be electrical, pneumatic or hydraulic. Sensors 40, 42 measure the slip. <IMAGE> |
