Description

Technical Field

[0001] The utility model relates to the technical field of wheel-side valves, and more particularly to a detachable wheel-side valve. Background Art

[0002] The central tire inflation and deflation system refers to a system installed on a wheeled vehicle, consisting of a compressed air source, a control circuit and control air path, a rotary sealing air chamber, a tire valve and corresponding pipelines. The wheel side valves used in the wheel side system of the central tire inflation and deflation system usually have two structures, piston structure and diaphragm structure. Commonly used detachable wheel side valves usually consist of a cover plate and a valve body. However, since the valve body is wrapped by the cover plate, the production of the cover plate increases the difficulty, thereby increasing the cost, and it is more time-consuming to position the wheel side system components in the central tire inflation and deflation system.

[0003] For example, publication number CN107701771A discloses a positive pressure wheel-side valve, which assembly includes a valve nozzle air pipe, an external air source connector, a wheel-side valve and a wheel-side valve bracket. The wheel-side valve includes an upper valve cover, a valve body and a lower valve cover. A first air chamber and a second air chamber are respectively provided between the upper valve cover and the lower valve cover and the valve body.

[0004] It can be seen from the above-mentioned public scheme that the wheel side valve is connected and positioned with the wheel side system component in the tire central inflation and deflation system through the wheel side valve bracket. Its efficiency is low due to the positioning in a single direction, and the valve body is wrapped by the upper valve cover and the lower valve cover, so that the chamber inside the upper valve cover and the lower valve cover needs to be designed and processed according to the shape of the valve body and the contour shape after the assembly is installed, which increases the processing difficulty and reduces work efficiency, thereby increasing the cost of the entire wheel side valve and reducing market competitiveness.
