Abstract
A differential drive with a differential housing (13) supported in a housing (12) has driving bevel gears (16, 17) and differential bevel gears (22, 23) which engage one another. The differential housing (13) includes a bearing projection (41) with a cylindrical bearing face (39). Furthermore, the differential housing (13) includes a radially extending connecting face (40) with bores (42) to receive coupling pins. A viscous coupling (26) is supported on bearings (55, 57) in a flange housing (47) flanged to the housing (12). The viscous coupling (26) includes a bearing bore (46) which associates the viscous coupling with the differential drive, receives a bearing projection (41) of the differential housing (13), with the flange housing (47) supporting the bearing carrier. Furthermore, a plug-in shaft (58) is provided which, for connecting the hub (32), includes teeth and which itself may be plugged into a toothed bore (60) of the driving bevel gear (17). The coupling housing (27) also includes bores (44) to receive coupling pins (45). After the viscous coupling (26) has been prefitted in the flange housing (47), an axial plug-in assembly procedure is carried out where coupling pins (45) and the plug-in shaft (58) establish a connection with the housing (12) of the differential drive.
