Controlled hydraulic differential for motor vehicle - has preassembled locking device provided as side extension of differential housing

摘要

The differential has an external housing (1) containing a driven differential housing (4) housing at least one spline wheel (11, 12) engaging two splines (15, 16) fitted to respective shafts (13, 14), a lamella disc packet (20) providing a differential lock between the differential housing (4) and one of the shafts (13, 14). The lamella disc packet (20) of the locking device (17) is contained in a coupling housing (19) with a cylinder (21) coaxial to the rotation axis containing a ring piston (22) acting on the lamella disc packet (20) via a pressure ring (23). The locking device (17) comprises a pre-assembled module and is provided as a side extension of the differential housing (4). USE - Motor vehicle electronic anti-locking braking regulation.
