The wheel grip hoops (2) are held over the tyre tread at the ends of radial arms with longitudinal adjustment. The radial arms form a rigid structure which is secured on the wheel disc (5) by rapid fitting hooks (8, 9). The system dispenses with the complex radial adjusters fitted to the wheel hub. The radial adjustment is secured by simple bolts (1'). The rapid fitting hooks engage the normal holes in the wheel disc and are secured by twisting. |
