Abstract

An electrically driveable drive axle ( 19 ) is disclosed for an all-terrain utility vehicle. The first drivetrain ( 20 ) has a first electric motor ( 21 ), a first transmission ( 22 ), and a first drive output ( 23 ). A second drivetrain ( 30 ) has a second electric motor ( 31 ), a second transmission ( 32 ), and a second output ( 33 ). The first drivetrain ( 20 ) and the second drivetrain ( 30 ) are arranged in a common housing ( 40 ) and/or on the common housing ( 40 ) where the first drivetrain ( 20 ) forms a first torque path and the second drivetrain ( 30 ) forms a second torque path. The first torque path and the second torque path are mechanically separate from one another. A corresponding vehicle is also disclosed.

First claim

The invention claimed is:

1 . An electrically drivable drive axle for an all-terrain utility vehicle, comprising:
a first drivetrain with a first electric motor, with a first transmission and with a first drive output; and a second drivetrain with a second electric motor, with a second transmission and with a second output; wherein the first transmission comprises a first spur-gear stage, a first bevel-gear stage, and a first planetary gear set, wherein the first spur gear stage connects an output shaft of the first electric motor to the first bevel-gear stage, and wherein the first planetary gear set is between the first bevel-gear stage and the first drive output; wherein the second transmission comprises a second spur-gear stage, a second bevel-gear stage, and a second planetary gear set, wherein the second spur gear stage connects an output shaft of the second electric motor to the second bevel-gear stage, and wherein the second planetary gear set is between the second bevel-gear stage and the second drive output; and wherein the first drivetrain and the second drivetrain are arranged in a common housing and/or on the common housing, and wherein the first drivetrain forms a first torque path and the second drivetrain forms a second torque path, the first torque path being mechanically separate from the second torque path; wherein the first drivetrain and the second drivetrain are arranged symmetrically about a vertical axis of the housing, and wherein the first electric motor is arranged in a direction of travel of the drive axle and the second electric motor is arranged counter to the direction of travel of the drive axle.

2 . The drive axle according to claim 1 , wherein:
the first spur-gear stage creates a first height offset of the first electric motor with respect to the first drive output; and the second spur-gear stage creates a second height offset of the second electric motor with respect to the second drive output.

3 . The drive axle according to claim 1 , wherein the first planetary gear set is of multi-stage configuration, and the second planetary gear set is of multi-stage configuration.

4 . The drive axle according to claim 1 , wherein the first bevel-gear stage is configured to divert the first torque path through 90°, and the second bevel-gear stage is configured to divert the second torque path through 90°.

5 . The drive axle according to claim 1 , wherein the first electric motor is arranged on the housing by means of a first flange connection, and the second electric motor is arranged on the housing by means of a second flange connection.

6 . The drive axle according to claim 1 , wherein the first drivetrain furthermore comprises a first immobilizing brake, and the second drivetrain furthermore comprises a second immobilizing brake.

7 . The drive axle according to claim 1 , wherein the housing is of multi-part form.

8 . The drive axle according to claim 1 , wherein the drive axle is configured to be steerable.

9 . A utility vehicle, comprising at least one drive axle according to claim 1 .
