ROTATIONAL SPEED DIFFERENTIAL RESPONSIVE TYPE TORQUE TRANSMITTING ASSEMBLY

摘要

A limited slip differential is disclosed which includes a first rotary element (30), a second rotary element (40), and hydraulic means including a plurality of reciprocal pistons (50) in slidable engagement with internal cam surface means (31) of the first rotary element (30). The hydraulic means includs an accumulator and fluid passage means (70,71) in fluid communication with the accumulator and each of pressure chambers (60) defined by the pistons (50). A pressure relief valve (100) is provided in the accumulator chamber (90) to prevent excessive increase in hydraulic fluid pressure in the hydraulic means.
