Driving force distribution differential gear mechanism unit for control possible automobile

摘要

A differential gear unit for motor vehicles for the controllable distribution of the driving power comprises a housing and a differential gear (4) disposed therein, the gear having two speed-changing transmissions (5) drivingly connected to the output shafts (7, 8) and to the input member (14) of the differential gear, and two hydraulically controllable clutches (24, 25). In order to avoid the transmission of rotations and to be easy to mount and access, an intermediate part (26) is disposed stationary on the housing between the two clutches (24, 25), the part comprising the hydraulic actuation device (56, 58), the pressure rings (35, 45) of the clutches (24, 25) are disposed on the side facing the intermediate part (26), the outer part (30) of the first clutch (24) is drivingly connected to the speed-changing transmission (5) and to the inner part (42) of the second clutch (25) via an intermediate shaft (37), and the inner part (32) of the first clutch (24) is drivingly connected to the first output shaft (7), and the outer part (40) of the second clutch (25) is connected to the second output shaft (8).
