TWIN-WHEEL DRIVE MODULE
First Claim
1. A twin-wheel drive module for driving two vehicle wheels arranged in axial spaced-apart relationship for rotation about two aligned axes of rotation, said drive module comprising:
- a first traction motor having a motor shaft disposed in parallel relation to the axes of rotation;
a first transmission having an input shaft connected to the motor shaft of the first traction motor and an output shaft in alignment with the axes of rotation;
a second transmission having an input shaft connected to the output shaft of the first transmission and an output shaft rotating around a common axis of rotation with the input shaft and configured to receive a first one of the vehicle wheels;
a second traction motor having a motor shaft disposed in parallel relation to the axes of rotation;
a third transmission having an input shaft connected to the motor shaft of the second traction motor and an output shaft in alignment with the axes of rotation; and
a fourth transmission having an input shaft connected to the output shaft of the third transmission and an output shaft rotating around a common axis of rotation with the input shaft and configured to receive a second one of the vehicle wheels.

Abstract
A twin-wheel drive module for driving two vehicle wheels which are disposed spaced axially from one another and rotatable around two axes of rotation aligned with one another. For driving each vehicle wheel, provision is made for a traction motor having a motor shaft disposed in parallel to the axes of rotation, a transmission having an input shaft which is connected to the motor shaft of the traction motor and an output shaft in alignment with the axes of rotation, and a second transmission. The second transmission has an input shaft, which is connected to the output shaft of the first transmission, and an output shaft which rotates around a common axis of rotation with the input shaft configured to receive the vehicle wheel.
