Track wheels of any size can be used and the wheels and their bearings are of robust design and do not require servicing. The track wheel (12) has a circular groove on its side face. The opening of the groove is wider than the diameter of the driving pinion of the motor. This groove has internal toothed rim engaged with the motor pinion. Between the wheel (12) and on the end support is fixed a cover with opening for the motor pinion and the axle of the wheel.
