| 摘要 |
The invention relates to a differential gear unit for motor vehicles, comprising a housing (1) with a differential gear (2) therein, a multiplication or reduction gear (3) and two controllable friction clutches (4,5), wherein the differential gear (2) comprises a drive body (8) and a first and a second output body (11,12) and according to the degree of engagement of the friction clutches (4,5) an additional torque is transmitted to the first or second output body (11,12). According to the invention, very high forces can be accommodated with the smallest construction and lowest possible wear, wherein the multiplication or reduction gear (3) comprises a first body (20) rotationally fixed to the drive body (8) of the differential gear (2) and a second body (21) rotationally fixed to the respective output bodies (11, 12) of the differential gear (2) by a friction clutch (4,5) and a third body (22) of the multiplication or reduction gear (3) is in the form of an annular gear, running in eccentric bearings (23) with an outer toothing (24) and an inner toothing (25). |
