Abstract

See full text

The transmission of torsional vibrations from a rotating driving shaft, at the output of an internal combustion engine, to a driven shaft, at the input of a manual transmission, are reduced or eliminated by employing a normally-engaged, oil-cooled wet clutch to interconnect the two shafts, the clutch being controlled to introduce a desired amount of slippage. Slipping the wet clutch to a relatively small extent allows the necessary torque to be transmitted, but any torque fluctuations in the driving shaft will be effectively absorbed and prevented from causing torsional vibrations in the drivetrain.
