Abstract
A drive system, especially a belt drive for a multi-axial vehicle running gear, has a drive drum about which the belt is looped and provided with a ring with entrainers which engage teeth on the belt when there is slip between the belt and the drum. Limited rotation of the ring relative to the drum may be effected by elliptical spring elements coupling the ring and the drum or by clutches on the drum which frequently lock the ring to the drum so as to effect control engagement of the entrainers with the belt teeth and positive drive of the belt by the drum.
