ABSTRACT:
A positive drive (10) utilizing a secondary clutch (76, 78, 132, 134) to frictionally couple the drive cam (22) and housing (12) to the output couplings (34, 36) regardless of engagement of the primary clutch (52, 54 and 66, 68) for preload and dampening purposes is provided. The magnitude of the torque transfer capacity of the secondary clutch between the drive cam and the faster rotating output coupling includes a fixed magnitude component supplied by a resilient biasing member (72 and 74) and a variable magnitude component which increases with increases in the magnitude of difference between torque transmitted to the slower and faster rotating wheels by the clutches associated therewith.
