Abstract

A transmission arrangement (1) for the controllable distribution of drive torque from an input element (2) to at least one output element (3), comprising a first transmission part region (4), namely a planetary gear mechanism, and an additional drive unit (5), the first transmission part region (4) being drive-connected directly or indirectly to the input element (2) and to the additional drive unit (5), and the first transmission part region (4) being drive-connected directly or indirectly to the output element (3).

Claims

1. A transmission arrangement for the controllable distribution of drive torque from an input element to at least one output element, comprising a first transmission part region, namely a planetary gear mechanism, and an additional drive unit, the first transmission part region being drive-connected directly or indirectly to the input element and to the additional drive unit, and the first transmission part region being drive-connected directly or indirectly to the output element.

2. The transmission arrangement as claimed in claim 1, wherein the first transmission part region is drive-connected indirectly via a second transmission part region, namely a differential transmission, to the output element.

3. The transmission arrangement as claimed in claim 2, wherein the differential transmission has a differential cage, the differential cage forming a planetary gear carrier of the first transmission part region.

4. The transmission arrangement as claimed in claim 1, wherein the additional drive unit is arranged offset in parallel to the output element.

5. The transmission arrangement as claimed in claim 1, wherein the additional drive unit is arranged coaxially with respect to the output element.

6. The transmission arrangement as claimed in claim 1, wherein the first transmission part region is configured as a multi-step planetary gear mechanism.

7. The transmission arrangement as claimed in claim 1, wherein the transmission arrangement is arranged on a secondary axle of an all-wheel-drive motor vehicle, the secondary axle being the output element.
