Problems solved by technology

However, when adjusting the tire pressure of the vehicle, it is also necessary to manually turn off and connect the wheel side valve after parking, and then perform inflation and deflation operations on the tire in the cab, which cannot realize the tire inflation and deflation function during the driving of the car.
Moreover, the rotary sealing air chamber is a single-channel radial rotary sealing structure. If the wheel side valve is not closed during driving, the sealing ring is easy to wear during high-speed rotation, causing air leakage and making the rotating sealing air chamber invalid.

Abstract

The invention provides an automobile tire central air inflation and deflation device for a hub reduction gear assembly, which consists of an air inflation electromagnetic air valve, an air deflation electromagnetic air valve, a control electromagnetic air valve, an air pressure sensor and a dual-channel rotary sealing air chamber which are arranged on an automobile chassis and an air control execution air valve arranged at the rotating position. By the automobile tire central air inflation and deflation device, the on-off of the air inflation electromagnetic air valve, the air deflation electromagnetic air valve and the air control execution air valve can be controlled directly by a cab electronic control unit to control the processes of air inflation and deflation of tires and the air pressure detection of the tires, and the pressure of the tires can be set and adjusted according to the ground condition during the running or stopping of automobiles.

Description

technical field [0001] The invention belongs to a central inflation and deflation control system for automobile tires, in particular to a central inflation and deflation device for automobile tires using a wheel-side reducer assembly. Background technique [0002] Existing part off-road vehicles are equipped with tire central inflation and deflation devices. The central inflation and deflation device is composed of a compressed air source, a control air circuit, a rotary sealed air chamber, a wheel side valve and corresponding pipelines, and is used to adjust the air pressure of the tires to meet the requirements of vehicle tires on different road surfaces. Different needs of air pressure. However, when adjusting the tire pressure of the vehicle, it is also necessary to manually turn off and connect the wheel side valve after parking the vehicle, and then carry out the inflation and deflation operation of the tire in the cab, which cannot realize the tire inflation and defl...
