Embodiment Construction

[0030] figure 1 A first embodiment of a transmission device 1 for a motor vehicle is shown, which is only shown schematically here. The motor vehicle has a first axle 2 and a second axle 3 , shown here only schematically, wherein the second axle 3 includes at least one first half axle 4 and a second half axle 5 . The transmission device 1 , the first axle 2 and the second axle 3 form at least part of a drive train of a motor vehicle. The transmission arrangement 1 has a coupling transmission 6 , a first superposition transmission 7 and a second superposition transmission 8 . The transmission device 1 has an input shaft 9 , which is operatively connected to a drive unit 10 of the motor vehicle, for example via a multi-gear transmission 11 .

[0031] The transmission device 1 also has an output shaft 12 , to which the first axle 2 is connected, for example via at least one gear stage 13 and / or an axle differential 14 . The functional connection from the coupling transmission ...

Abstract

The invention relates to a gearbox unit (1) for a motor vehicle, wherein the motor vehicle has a first wheel axle (2) and a second wheel axle (3). The second wheel axle (3) is composed of at least onefirst sub-axle (4) and one second sub-axle (5). The following are provided: a first connecting shaft (15) which is operatively connectible to the first sub-axle (4), a second connecting shaft (16) which is operatively connectible to the second sub-axle (5), and a coupling gearbox (6) which has a drive input shaft (9) operatively connectible to a drive assembly (10) of the motor vehicle and a drive output shaft (12) operatively connectible to the first wheel axle (2), wherein, by way of said coupling gearbox (6), the drive input shaft (9) is operatively connected in a torque-splitting fashionto the first connecting shaft (15) and to the second connecting shaft (16), and wherein the drive output shaft (12) is operatively connectible, by means of a first coupling (32) and a second coupling(33), to the drive input shaft (9) such that each can shift separately, wherein a first overlay gearing (7) is provided in the operative connection between the first coupling (32) and the drive inputshaft (9), and a second overlay gearing (8) is provided in the operative connection between the second coupling (33) and the drive input shaft (9).

Description

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