摘要

The driving wheel (1) has a tread lining (2) that is stand in an operative connection with a traction mechanism. A coil spring (7) is formed in such a way that two spring coils (8',8'') are successively inserted in a retainer (6) in a circumferential direction, where the retainer lies within the radial range on different radii.
