Inflation/deflation valve assembly for central tire inflation/deflation system of automobile

Abstract

The invention discloses an inflation / deflation valve assembly for a central tire inflation / deflation system of an automobile and relates to tire inflation / deflation technology of a vehicle. The inflation / deflation valve assembly comprises an inflation valve cover, a hexagon lobular socket head cap screw, a spring washer, an inflation / deflation valve body, a deflation solenoid valve cover, a hexagon socket tapered screw plug, a first steel ball, a gasket, a diaphragm, a first spring, an O-ring, a second steel ball, a curved single coil spring lock washer, a solenoid valve assembly, a dust-proof cushion, a second spring and a slotted screw plug. The inflation / deflation valve assembly has the advantages of big air passage size, high inflation / deflation speed, compact structure, small volume and convenient assembly, and is applicable to a driving state or a parking state of the vehicle, so that a driver can perform inflation, an deflation or pressure measurement on the tires of the vehicle through simple operation in a driving cab so as to regulate the pressure of the tire; and therefore, the capacity of the tires or the vehicle for passing complex road surfaces, such as desert, muddyroad surfaces or snowy and icy road surfaces and the like is improved, and the maneuverability and the viability of the vehicle are improved.

Description

Technical field [0001] The invention relates to a vehicle tire charging and discharging technology, in particular to a charging and discharging valve assembly of an automobile tire central charging and discharging system. Background technique [0002] The central inflation and deflation system of automobile tires is a system that can detect and adjust the tire pressure at any time while the automobile is driving (or when it is stopped). Its main function is: when the car passes through soft ground such as deserts, beaches, swamps, muddy ground, and icy and snowy roads, the system can quickly reduce the tire pressure and increase the tire contact area; on the one hand, the tire subsidence can be reduced. Soil resistance is reduced; on the other hand, due to the increase in the number of tires embedded in the soil, the propulsion of the soil is increased, the traction is greatly increased, and the passing of the car is improved. [0003] When the height of the carrying vehicle is re...

AI Technical Summary

Problems solved by technology

[0008] 1. The airway diameter is small and the deflation speed is slow;

[0009] 2. The overflow valve is prone to failure, which affects the stability of the entire system;

[0010] 3. The number of installation parts is large and the volume is large, which affects the installation efficiency;

[0011]4. When the number of bridges is required to be different, the bottom plate needs to be reprocessed, and the versatility is poor
