Therefore, the antiskid chain made of the beef tendon cannot be used for a long time, and potential safety hazards exist.

Rubber anti-skid chains: rubber materials are used for automobile tires. The rubber has the greatest characteristics of excellent elasticity, shape recovery after external force disappears, wear resistance, good friction force and the like. Is an ideal material for a snow chain, but the cost of the material is high, so the price of the snow chain is high.

As shown in fig. 1 and 3, the snow chain for vehicle wheels of the present invention comprises at least one antiskid member 1 arranged around and covering the tire tread of the wheel and a fixing mechanism 2 for fastening the antiskid member 1 to the tire tread of the wheel; the fixing mechanism 2 of the snow chain of the present invention comprises a center ring 2-1 for being disposed at a hub position of a wheel and at least two clamping devices for providing a fixing force of the antiskid member 1 to a tire surface, as shown in fig. 1, the clamping devices being provided in six. In addition, each clamping device comprises a connecting part 2-2 for fixing two adjacent antiskid parts 1 and a spring 2-3 which is connected with the connecting part 2-2 at one end and is connected with the center ring 2-1 at the other end and is used for providing spring force in the radial direction of the wheel during work so as to enable the connecting part 2-2 to be tightly buckled on the tire tread, and a spring sleeve 2-4 for shielding the spring 2-3 is arranged outside the spring. As shown in figure 1, the inner end of the spring 2-3 along the radial direction of the wheel is connected with the circular ring through a circular ring 2-5 arranged on the central ring 2-1, a plurality of circular rings are arranged along the circumference of the central ring 2-1, and the number of the specific clamping devices can be selected and arranged according to the requirement, and is at least two. The spring 2-3 provides an elastic force after the connecting member 2-2 is connected to the antiskid member 1 so that the connecting member 2-2 is clamped on the tread of the wheel and the antiskid member 1 is fixed on the tread. Here, the number of the nonslip members 1 may be selected as needed, and is preferably such that the whole tread of the tire can be completely surrounded and covered.

Also, in the present invention, the clamping devices are distributed substantially uniformly in the circumferential direction of the center ring 2-1, and the substantially uniform distribution means that the forces acting on the center ring 2-1 by the springs 2-3 in the respective clamping devices are balanced integrally without being released from the tire after clamping the tire, and it is of course preferable that a plurality of clamping devices are distributed uniformly in the circumferential direction of the center ring 2-1, and this is achieved by providing a positioning position for each clamping device on the center ring 2-1, and the positioning position may be formed by providing a recess on the inner circumferential side of the center ring.
