This invention relates to an anti-skid device for motor vehicles, which device is of the known kind at which a friction pulley abuts a drive wheel and the pulley is provided with chain links, the free ends of which are thrown in between the tire and the ground. The invention is characterized in that the friction pulley (8,19) is supported on one end of an arm (6), which at its other end is supported pivotally about a journal (5) rigidly connected to the vehicle or the spring system thereof, and pneumatic means (10) are provided by action of a control means in the driver's cab to swing the arm (6) with the pulley (8,19) from a protected non-operative position to a pneumatically resilient contact against the tire (23). |
