ABSTRACT:
A differential drive mechanism for automotive vehicles includes a rotary housing rotatably mounted within a support casing and being in drive connection with an input shaft, a pair of split drive axles rotatably carried by the rotary housing coaxially with the rotational axis thereof for relative rotation, a pair of axially spaced pistons slidably disposed within a sealed cylindrical chamber in the rotary housing to be axially inwardly moved by a thrust force applied thereto, a pair of axially spaced clutch assemblies disposed between the pistons for transmitting drive torque from the input shaft to the drive axles when engaged by axially inward movement of the pistons, and an annular intermediate element disposed between the clutch assemblies for applying the thrust force acting on one of the clutch assemblies to the other clutch assembly, wherein the thrust force is produced in response to differential rotation between the rotary housing and the drive axles and applied to the pistons.
