Abstract: There is disclosed a device for driving four wheels of a car at all times. In this device, a differential is provided between the left front wheel shaft and right rear wheel shaft and likewise a differential is also provided between the right front wheel shaft and left rear wheel shaft so that said two differentials can be driven by the same driving source.

Abstract: The invention is concerned with a drive assembly (8) comprising a differential (16). The differential (16) comprises a driving carrier (18) and two driven output gears (19) connected to joints (11) to driveshafts (12). The assembly (8) also comprises a coupling (48) by which one of the gears (19) may be connected directly to the carrier (18). The joint (11) associated with said gear (19) is positioned outside the differential (16) directly adjacent thereto and extends coaxially around an outer part (26) of the joint (11). An inner part of the coupling (48) is connected to the outer part of the joint (11) and an outer part (31) of the coupling is connectable to the carrier (18). The coupling (48) may be a viscous coupling.
