Description

Antiskid system and antiskid device for automobile tire

technical field

The invention belongs to the field of auto parts, and in particular relates to an anti-skid system and an anti-skid device for automobile tires.

Background technique

In winter especially in the ice and snow weather in Northeast China, traffic accidents are not uncommon when automobiles run on icy roads or particularly slippery roads. Therefore, many automobiles are equipped with anti-skid devices to avoid accidents.

The main measures of the current prior art to solve the safety problem of vehicles in snowy weather: a method is: tire anti-skid devices are installed on the drive wheels, the most common is anti-skid chains; another method is: use snow tires. The working principle of the anti-skid chain is to concentrate the gravity of the vehicle on several points of the anti-skid chain, generate huge pressure, and roll through the ice and snow layer to reach the road surface, thereby increasing the friction to prevent slipping and increasing the safety performance of the vehicle. Anti-skid chains are generally made of iron chains, tendon chains or rubber chains. Iron chains are strong and durable, but they are noisy, difficult to disassemble, and cause serious wear to tires and damage to road surfaces; however, the structures of tendon chains and rubber chains are in There are several steel nails on the tendon or rubber. Although it is relatively light, it is also troublesome to disassemble and assemble, and is not durable. And the main principle of existing vehicle antiskid tire is to increase the frictional force between tire and ground by the variation of tread pattern, groove, material etc. and arranging some attachments on the tread surface, thereby prevents wheel from slipping. However, it is generally only used in specific environments, and is not always used on roads, and the cost of use is high. The market is badly in need of a novel automobile tire anti-skid device that has simple structure, reliable and convenient use, and can cooperate with automobiles to run on snowy and slippery road surfaces.
