ABSTRACT:
This invention relates to a unique transmission system for applying torque from an engine flywheel to the drive train of an automotive vehicle including a long travel viscous damped torsional damper driven by the flywheel and coupled to a continuously variable transmission which in turn is coupled to a wet drive clutch, the output of which is connected to an output counter shaft for the automotive drive train. An important part of the unique combination is the long travel viscous damped torsional damper of the invention which includes an enclosed, effectively sealed housing contains input and output members coupled through a plurality of series parallel spring sets and immersed in a viscous medium to provide effective viscous damping matched to the effective spring rate of the mechanical damping system to accommodate both transient and steady-state vibrational torques. The damper is especially useful with the continuously variable transmission but is useful in other applications as well.
