Limited slip differential.

摘要

A limited slip differential (10) includes a differential carrier for supporting rotatably a differential case (12), surrounding the differential case (12) and first and second frictional materials (18,20) and having a piston chamber (60) connected to an outside pressure source, a first piston (26) disposed shiftably and unrotatably in the piston chamber (60), a second piston (28) disposed rotatably together with the first frictional materials (18) and shiftably along a rotary axis of the differential case (12) and a thrust bearing (30) disposed between the first and second pistons (26,28).
