Bridge wheel valve assembly of central inflation and deflation system of automobile tyres

Abstract

The invention discloses a bridge wheel valve assembly of a central inflation and deflation system of automobile tyres, relating to the technology of inflation and deflation of automobile tyres. The invention comprises a bridge wheel valve cover, an inner hexagon spline fillister head screw, a spring washer, a bridge wheel valve body, a bridge wheel electromagnetic valve cover, a pressure sensor, a gasket, a membrane, a spring, an O-shaped ring, a steel ball, a curved single coil spring lock washer, an electromagnetic valve assembly and a dust-proof mat. The bridge wheel valve assembly has large air passage drift diameter, rapid deflation speed, compact structure, small volume and convenient assembling, and under a running or stopping state of vehicles, the bridge wheel valve assembly is suitable for a driver to inflate or deflate the automobile tyres or test the pressure of the automobile tyres through simple operations in the driving room, so as to regulate the pressure of the tyres, thereby improving the capability of tyres or vehicles running on desert, muddy or snow ice and other complex pavements and improving the maneuverability and viability of vehicles.

Description

technical field [0001] The invention relates to vehicle tire inflation and deflation technology, in particular to an axle wheel valve assembly of a central inflation and deflation system for automobile tires. Background technique [0002] The car tire central inflation and deflation system is a system that can detect and adjust the tire pressure at any time when the car is running (or stopped). Its main function is: when the car passes through deserts, coastal beaches, swamps, muddy ground and other soft ground and ice and snow roads, the system can quickly reduce the tire pressure and increase the ground contact area of ​​the tire; on the one hand, the tire subsidence and The soil resistance is reduced; on the other hand, due to the increase in the number of tire patterns embedded in the soil, the propulsion force of the soil is increased, the traction force is greatly increased, and the passability of the car is improved. [0003] When the height of the vehicle is limited...

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
