Special terrain travelling wheel auxiliary device of car

Abstract

The invention discloses a special terrain travelling wheel auxiliary device of a car, and belongs to the technical field of car wheel sliding prevention. The special terrain travelling wheel auxiliarydevice comprises a fixed disc (1), at least three connecting rods (2), a fixing part and an anti-sliding part, wherein the fixed disc (1) is fixed with a hub through the fixing part; the three connecting rods are arranged in the forms of radioactive bars, ends of connecting rods (2) are connected to the outer side walls of the fixed disc (1), the other ends of the connecting rods (2) are connected to the side surface of the anti-sliding part; the anti-sliding part and the fixed disc (1) are positioned at the same sides of the connecting rods (2). According to the special terrain traveling wheel auxiliary device of the car disclosed by the invention, the fixed disc (1) is fixed on the hub through the fixing part, ends of the connecting rods (2) are connected to the anti-sliding part, the inner wall of the anti-sliding part abuts against the circular-arc tyre surfaces of the wheels, the other ends of the connecting rods (2) are connected to the fixed disc (1), and the connecting rods (1) are in the forms of radioactive bars, so that the wheel circular-arc tyre surfaces are concave and convex surfaces, and therefore, wheel friction force is increased. The special terrain travelling wheel auxiliary device of the car solves the problems that an existing car anti-sliding chain is great in noise, is difficult in disassembly and is severe in abrasion on tyres.

Description

technical field [0001] The invention discloses an auxiliary device for driving wheels on special terrains of automobiles, which belongs to the technical field of anti-skidding of automobile wheels. Background technique [0002] At present, the road conditions in our country are mostly good, and cars can be driven on flat roads that can provide sufficient adhesion for tires. However, in winter, the roads in some areas are prone to snow and ice, which makes the car easily slipped and trapped in snow and mud; These problems are often encountered in excavation and other work. And the prior art mainly overcomes skidding by setting anti-skid chains on the outside of the tires, but the major disadvantages of the iron chain automobile anti-skid chains that are mainly used now are that noise is large, difficulty in dismounting and serious wear and tear on tires. Simultaneously when wheel falls into accumulated snow or muddy ground, existing automobile anti-skid device just helps li...
