Abstract
A damping system for a drive train having a cam coupling mechanism which advances an intermediate member axially along a driven shaft under high torque loads. The intermediate member is spring biased and is associated with a variable volume chamber containing fluid. Damping mechanisms are positioned concentrically within the driven shaft and are in communication with the variable chamber. The damping mechanisms include a check valve for one-way communication with the lubricant supply system of the associated engine, and a flow restricter for generating damping energy. An accumulator piston accommodates volume changes resulting from operation of the piston and allows for leakage flow from the system to insure renewal of oil without temperature build-up and oil deterioration.
