ABSTRACT:
A differential rotation control device with a hydraulic assembly includes two torque transmission assemblies. Each assembly has a first rotor with a pump-driven arrangement secured to a drive shaft which is common to both of the torque transmission assemblies, and a second rotor with a torque-receiving arrangement rotatably supported on the drive shaft. The torque-receiving arrangement is rotated when hydraulic power is applied to the pump-driven arrangement so that the rotation speed ratio between the first and second rotors can be variably set. The two pump assemblies each have a pump-driving arrangement assembled to the first rotor for constituting a circular route together with the pump-driven arrangement for circulating fluid. A pump-regulating arrangement controls fluid supplied to the pump-driven arrangement when the drive shaft is rotated relative to a pump-stator to which the pump-regulating arrangement is secured. A differential rotation control device applies different control ratio between the fluid amounts supplied to the pump-regulating arrangement of the pump assemblies.
