Drive device for four-wheel-drive motor vehicles
Abstract:
A drive device for four-wheel-drive motor vehicles includes a primary axle which is driven by a drive assembly via a center differential and a secondary axle which is driven via the primary axle and via a transmission. Side differentials are arranged on the output elements of the primary axle coaxially to the center differential of the primary axle. The drive elements of the side differentials have a drive connection to the output elements of the center differential, and the output elements of the side differentials have a drive connection to the driveshafts of the primary axle and to the driveshafts of the secondary axle via multiple belt drives.
