Description

Reinforced tire antiskid device

Technical Field

The invention relates to the field of automobile antiskid, in particular to a reinforced tire antiskid device.

Background

With the rapid popularization of automobiles, the number of motor vehicles is increasing day by day, and the important problem in daily life is how to reduce wheel slip accidents for the safe driving of automobiles on severely muddy and wet road surfaces and frozen road surfaces in winter.

At present, a method of additionally installing an antiskid chain is mainly adopted to solve the problem of preventing the wheel from skidding; the antiskid chain in the current market mainly comprises a beef tendon chain, a rubber chain and an iron chain. The beef tendon chain and the rubber chain have basically the same structure, shape and size, but the rubber anti-skid chain has basically the same performance except that the tensile strength is higher than that of the common beef tendon anti-skid chain due to the difference of materials and internal tension lines; although the two kinds of the materials have small damage to the vehicle and the road surface, the bearing capacity and the damage resistance of the two kinds of the materials are far lower than those of an iron chain type, and the manufacturing cost is relatively high; when heavy load, the driving distance are very far or the vehicle runs on the cruel road surface which absolutely tests the quality of the antiskid chain, the antiskid chain is basically scrapped once, if the condition that the quality of the antiskid chain is tested on ice road slopes, off-road environments and the like, the antiskid chain can be scrapped once being broken, and great safety problems can be brought immediately. The iron chain has a wide application range and is the most common and classic anti-skid chain; although the price is cheap, firm and durable, but the disadvantages are that the noise is large, the dismounting is difficult and the weight is heavy, when the vehicle runs, the iron chain can generate the mutual movement between the iron chain and the ground and the tire, so that the tire is damaged, and the abrasion to the tire and the road surface is serious, such as blunt knife contusion. And because the three anti-skid chains are fixed with the wheels in a binding mode, when the anti-skid chains work, force is mainly transferred between the anti-skid chains and the wheels by friction force, when the force applied to the chains on the ground is greater than the friction force between the chains and the wheels, the chains and the wheels can slide relatively due to the reason that the chains cannot be fixed by binding and are fastened sufficiently, the working efficiency is reduced, and the weak chains are easy to break due to local concentrated stress, so that the chain becomes invalid.

Summary the main technical disadvantages of the prior anti-skid chains are: the chain and the tire are easy to slide relatively, the stress is uneven, the noise is large, the disassembly and the assembly are difficult, the abrasion to the road surface and the tire is large, the bearing capacity of the chain is small, the force is easy to concentrate, the fracture is easy, and the safety and the reliability are low.

The technical problems reflected above are therefore a problem to be solved urgently by those skilled in the art.
