The device has a traction device (4) for attaching a trailer (2) to a tractor (1), and a measuring device at the traction device for determining a relative strength between the tractor and the trailer. The measuring device is connected with a control device (5) for controlling a wheel driving device (3) depending on the relative strength. The driving device transmits effective driving power and braking power to the trailer hydrostatically, electrically or electromagnetically, where the power is automatically adapted corresponding to land and driving conditions. An independent claim is also included for a method of driving a trailer attached to a tractor. |
