## Abstract

A drive arrangement in a vehicle having front and rear ground engaging means and steering means, has a differential transmission, a differential lock, a planetary final drive on each side of the vehicle and a motor acting onto one member of the planetary final drives. The motor is controlled depending on the steering angle such, that it provides for a difference in the drive speed on the left and the right side.

## Claims

### Claim 1

A drive arrangement in a vehicle having front and rear ground engaging means and steering means, wherein the drive arrangement for at least one of the front and rear ground engaging means comprises a differential transmission, a differential lock, a planetary final drive on each side of the vehicle and a motor acting onto one member of the planetary final drives depending on the steering angle and in inverse direction.

### Claim 2 (depends on 1)

The drive arrangement according to claim 1, wherein the motor acts on a ring wheel of the planetary final drives.

### Claim 3 (depends on 1)

The drive arrangement according to claim 1, wherein the motor is at least one of a hydraulic motor and an electric motor.

### Claim 4 (depends on 1)

The drive arrangement according to claim 1, wherein at least one of one motor acts on several planetary final drives via a counter rotating idler wheel and on each side one motor acts on one planetary final drive.

### Claim 5 (depends on 1)

The drive arrangement according to claim 1, wherein the steering means acts on at least one of an articulated joint between a front and a rear part of the vehicle, on the front ground engaging means, and on the rear ground engaging means.

### Claim 6 (depends on 1)

The drive arrangement according to claim 1, wherein at least one of the front ground engaging means and the rear ground engaging means comprises a bogie carrying wheels spaced in a driving direction.

### Claim 7 (depends on 1)

The drive arrangement according to claim 1, wherein a control device receives signals from a steering sensor at the steering means and a sensor at the differential lock and emits a signal to the motor.
