Problems solved by technology

[0003] How to inflate and deflate the tires while the vehicle is running, and how to connect the air path from the stationary body to the rotating wheels is a major problem in the central inflation and deflation technology. At present, the single-pipeline mode is widely used. This structure In order to inflate, deflate and measure the pressure of the tire, either a manual switch valve is installed on the wheel, or a special tire valve wit

Abstract

The invention belongs to a vehicle control component, and in particular relates to a gas circuit structure for a tire central gas charging and discharging system of a sports utility vehicle. The structure comprises a hub, wherein a steering knuckle is arranged in the hub; an end cover is arranged on the side end face of the hub; a cavity is formed between the end cover and the steering knuckle; a sealing ring and a sealing ring are respectively arranged between the steering knuckle and the hub; a static part of a gas circuit II and a static part of a gas circuit I are formed on the steering knuckle; a rotary part of the gas circuit I is formed on the hub; a gas outlet of the gas circuit II is formed on the end cover; the static part of the gas circuit II and the gas outlet of the gas circuit II are communicated with the cavity; and the rotary part and the static part of the gas circuit I are respectively communicated with the sealing rings. The structure has the advantages that: a double-gas circuit structure of a wheel assembly is simple, the design difficulty of other components of the tire central gas charging and discharging system is greatly reduced and the reliability of the whole system is improved.

Description

technical field [0001] The invention belongs to a vehicle control component, in particular to an air circuit structure of a tire central inflation and deflation system for an off-road vehicle. Background technique [0002] The road surface of off-road vehicles is relatively complicated, and often needs to be driven on muddy and soft roads. According to the theory of vehicle ground mechanics, under the condition of certain ground friction coefficient and other conditions, the larger the ground contact area of ​​the tire, the greater the ground traction force obtained by the vehicle. big. Therefore, by adjusting the tire pressure and changing the tire contact area, it can play a role in changing the traction of the vehicle. Therefore, the passing performance of the vehicle is enhanced to varying degrees with the degree of reduction in tire pressure. [0003] How to inflate and deflate the tires while the vehicle is running, and how to connect the air path from the stationary...
