Abstract
An anti-skid arrangement for a vehicle is disclosed. The anti-skid arrangement includes a friction wheel including a hub and a ring arranged around the hub, and a chain plate attached to the hub, wherein the chain plate includes several chains intended to be thrown under the tire in order to increase friction between the tire and the ground. The hub includes two parts clamping the ring. Further, an inner side of the ring is provided with grooves extending in a tangential direction along the ring and facing each hub part, and the two parts are provided with protrusions engaging the grooves. The engagement between the tangential grooves and the protrusions in the hub will secure the ring firmly, even when the tread of the ring is worn down.
