ABSTRACT:
A speed-sensitive, limited-slip, geared differential mechanism for transferring driving torque to each of two torque output shafts. Side gears located in a planetary gear carrier housing, one side gear being drivably connected to one pump member of a positive displacement pump and the planetary gear carrier being connected to another pump member. The pump is supplied with silicone fluid from a fluid reservoir. The pump creates a hydrostatic torque bias when differential motion of the side gears occurs as silicone fluid circulates through the pump.
