Anti-skidding device applied to automobile tires

Abstract

The invention relates to an anti-skidding device applied to automobile tires. The anti-skidding device comprises an inner fixed hub and an outer support hub, wherein the outer support hub is located at the outer side of the inner fixed hub; a plurality of anti-skidding unit bodies are fixed on the outer side wall of the outer support hub; each anti-skidding unit body comprises a support body and aconnection shell; the cross section of each support body is arc-shaped; an inwardly concave surface of each support body faces the outer support hub; each connection shell is located between each support body and the outer support hub; an adjustment cavity is formed between each connection shell and each support body; each anti-skidding unit body also comprises an elastic shell; each elastic shell is located on one side opposite to each connection shell of each support body; a molding cavity is formed between each elastic shell and each support body; each support body is provided with two through holes for communicating each adjustment cavity and each molding cavity; the two through holes are respectively located at the left end and the right end of each support body; the molding cavitiesand the adjustment cavities are filled with hydraulic oil. According to the anti-skidding device applied to automobile tires, the contact area between the anti-skidding device and the ground can be increased by the deformability of the elastic shells, so that the friction force between the ground and the anti-skidding device is improved; the controllability and the braking performance of the automobiles are improved; the safety of driving is ensured.

Description

technical field [0001] The invention relates to an anti-skid device for automobiles, in particular to an anti-skid device for automobile tires. Background technique [0002] It is known that when the vehicle wheels are driving on snowy ground, the snow on the road surface will reduce the friction between the road surface and the tires, making the braking performance of the vehicle worse and prone to skidding. In order to ensure driving safety, tire snow chains are generally installed on cars. Common tire snow chains on the market are all made of ordinary iron chains through simple processing, and the structure and material selection are single. After such anti-skid chains are installed, the noise and vibration of the vehicle when running on a hard road surface are quite serious, causing greater distress to the physiology and psychology of drivers and passengers. And, because similar anti-skid chains are stressed unevenly during the rolling process of tires, relative slidin...

Problems solved by technology

In addition, the traditional chain-shaped tire anti-skid chain has a small contact area with the ground, which produces concentrated pressure on the road surface, damages the road surface, pollutes the environment, and also reduces the service life of the anti-skid chain
