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.
Claims4
A drive device for a four-wheel-drive motor vehicle, comprising:
- a drive aggregate transversely mounted in the four-wheel-drive motor vehicle relative to a longitudinal axis of the motor vehicle;
- a primary axle having a center differential, said center differential being integrated in a housing of the drive aggregate, said drive aggregate mounted on the primary axle;
- a secondary axle;
- and
- side differentials arranged coaxial to the center differential and attached axially adjacent to the housing of the drive aggregate, said side differentials having input elements and output elements, said input elements being drivingly connected to output elements of the center differential, said output elements of the side differentials being drivingly connected with drive shafts of the secondary axle, and with drive shafts of the secondary axle via separate belt drives.
