Technical Field

The invention belongs to the technical field of vehicle safety, and particularly relates to an anti-skid tire for a vehicle.

Background

Along with the rapid development of social economy, the number of motor vehicles is rapidly increased, and meanwhile, traffic accidents are gradually increased, particularly, when the motor vehicles enter winter, the vehicles slip out of control due to wet and slippery roads or icy roads in rainy and snowy weather, or tires are locked during emergency braking, the vehicles still lose control due to inertia sliding, so that the traffic accidents are easily caused, even major accidents of multiple vehicle chain collision are caused, and the life safety of drivers and pedestrians is seriously damaged.

In order to improve the anti-skid effect of vehicles, reduce and avoid traffic accidents and guarantee the safety of life and property of people, vehicle drivers take many safety measures, for example, ABS devices are assembled on wheels or antiskid chains are installed on tires, wherein the ABS devices are expensive, only high-grade vehicles are equipped, middle-grade and low-grade vehicles are not installed, middle-grade and low-grade vehicles in China account for the vast majority, and the ABS devices applied to a small part of high-grade vehicles have little effect on reducing traffic accidents in China, so that the traffic accidents caused by vehicle skidding cannot be fundamentally solved. Although the antiskid chain can play certain antiskid, the installation is troublesome to the antiskid chain to in case need use for a long time and then can damage the tire, very easily cause the flat tire, cause bigger dangerous accident, therefore the practicality is very poor.

Disclosure of Invention

In order to solve the above technical problems, an object of the present invention is to provide a vehicle antiskid tire.

According to one aspect of the invention, a vehicle antiskid tire is provided, which comprises a tire, an antiskid telescopic component and an antiskid telescopic foot, wherein the antiskid telescopic component is positioned in the tire and drives the antiskid telescopic foot of the antiskid telescopic component to extend out of or retract back from the tire tread through a driving mechanism of the antiskid telescopic component.

Further, the antiskid telescopic assembly is formed in the tire. The anti-skidding telescopic component is formed at the thickened central part in the tire tread when the tire is produced, and other parts of the tire tread are consistent with the thickness of a normal tire, so that the influence on the shock absorption of the tire is reduced as much as possible.
