wheel system assembly

Abstract

The invention relates to a wheel-side system assembly. The wheel-side system assembly comprises a valve gas pipe, an external gas source joint, a wheel-side valve and wheel-side valve brackets, wherein the wheel-side valve comprises an upper bonnet, a first spring, an upper combined diaphragm, an upper sealing lip, a valve core, a valve body, a lower combined diaphragm, a second spring and a lower bonnet, the valve core is arranged in the upper sealing lip, the upper sealing lip is arranged in the valve body and in a first gas chamber which communicates with a central gas channel of the valve body through the upper sealing lip, a second gas chamber communicates with the central gas channel and a gas vent in the wheel-side valve, and the first gas chamber and a third gas chamber communicate with an in-hub gas channel port. The wheel-side system assembly is equipped with the wheel-side valve adopting an upper-lower double-diaphragm structure, so that the stability and the reliability of inflation or deflation can be improved, the sealing performance of the wheel-side valve can be enhanced, and the inflation or deflation speed and the execution efficiency of a CTI / DS (central tire inflation / deflation system) can be increased.

Description

Technical field [0001] The invention relates to the field of tire central inflation and deflation systems, in particular to a wheel rim system assembly. Background technique [0002] When a vehicle is driving on a good road, it is desirable to drive at the highest possible speed in order to give full play to its maneuverability. This requires that the inflation pressure of the tire be increased as much as possible to reduce the rolling resistance and the loss of tire deformation energy. At the same time, when vehicles pass through complex roads (such as deserts, beaches, swamps, muddy ground and other soft ground, and icy and snowy roads), it is not only hoped that the vehicle can pass smoothly, but also that the vehicle maintains a certain off-road speed, which requires reducing tires. Inflation pressure, on the one hand, can reduce the amount of tire subsidence and soil resistance. On the other hand, due to the increase in the number of tires embedded in the soil, it increases ...

AI Technical Summary

Problems solved by technology

Among them, the wheel side valve uses a single air channel (air chamber) to realize inflation and deflation, and the inflation and deflation speed is relatively slow, which affects the execution efficiency of the tire central inflation and deflation system
