Abstract

The invention relates to a transmission device (1) for a motor vehicle, wherein the motor vehicle has a first axle (2) and a second axle (3), wherein the second axle (2) comprises at least a first half-shaft (4) and the second half axis (5). It is provided with a first connecting shaft (15) that can be operatively connected with the first half shaft (4), a second connecting shaft (16) that can be operatively connected with the second half shaft (5) and has a power shaft that can be connected with the motor vehicle. A coupling transmission (6) of an input shaft (9) operatively connected to the device (10) and an output shaft (12) operatively connected to the first wheel shaft (2), wherein the input shaft (9) and the The first connecting shaft (15) and the second connecting shaft (16) are effectively connected in a way of distributing torque, wherein the output shaft (12) can be respectively connected by means of the first clutch (32) and by means of the second clutch (33). Separately switchable and operatively connected to the input shaft (9), wherein a first superimposed transmission (7) is provided in the operative connection between the first clutch (32) and the input shaft (9), between the second clutch (33) and In the operative connection between the input shafts (9) there is a second superposition transmission (8).

Description

technical field [0001] The invention relates to a transmission device for a motor vehicle, wherein the motor vehicle has a first wheel axle and a second wheel axle, wherein the second wheel axle comprises at least a first half shaft and a second half shaft. Background technique [0002] Such a transmission arrangement serves, for example, to transmit torque between a power plant of a motor vehicle and the at least two wheel axles of the motor vehicle. The first axle and the second axle are thus connected to the power plant through the transmission device. The first wheel axle and the second wheel axle are thus at least temporarily driven wheel axles, so that the motor vehicle can be a four-wheel drive motor vehicle. The first wheel axle is, for example, the front axle of the motor vehicle, and the second wheel axle is the rear axle of the motor vehicle. But it can also be designed in reverse. [0003] A transmission device of the type described can, for example, be provid...
