摘要

Each axle is provided with an independent electric motor (5). Each electric motor is connected to a corresponding axle through a step-up gear (4). Automatic controllers (7,8) adjust the number of revolutions of the electric motors through the corresponding frequency changers (6). A switch (11) enables the direction of rotation of the electric motors to be selected.
