ABSTRACT:
A torsional vibration damper assembly providing a variable torsional deflection rate having a very low initial deflection rate. The assembly utilizes a vibration damper assembly having a set of compression springs providing the torsional deflection rate for the main stage of relative angular displacement between the input and output members and an auxiliary resilient means to provide an extremely low initial torsional deflection rate; the auxiliary means comprising sets of interengaged free play splines between the barrel of the clutch hub and a separate hub flange with springs between the sets of teeth to preload the splines lightly in either the drive and/or coast directions.
