Abstract
A drive for an industrial truck with at least one drive motor for driving a wheel of the industrial truck and at least one steering motor for supporting a steering movement of the wheel around a steering axle also features a drawbar for guiding the steering or driving movement by applying a load on the drawbar. The drive motor also rotates upon a steering movement of the wheel, whereas the drawbar is connected in a torque-proof manner, relative to the steering axle, with a component also rotating upon a steering movement of the wheel.

A drive system for an industrial truck, comprising:
- a drive motor mounted to a vehicle frame of the industrial truck and operably configured to provide driving movement to a drive wheel mounted on a rotatable steering axle of the industrial truck;
- a steering motor operably configured to provide a steering movement to the steering axle;
- a drawbar that controls the steering movement and driving movement responsive to a load applied by an operator of the industrial truck to the drawbar;
- the drive motor rotatable relative to the vehicle frame upon rotation of the steering axle upon application of the steering movement;
- and
- the drawbar configured so as to also rotate with the drive motor upon the steering movement of the drive wheel.
The drive system as in claim 1, wherein the drawbar is connected in a torque-proof manner to a component of the steering axle that rotates with the steering movement of the drive wheel.
