Tire pressure maintaining and adjusting system based on air suspension system

The invention relates to a tire pressure maintaining and adjusting system based on an air suspension system. The system is composed of a silencer, a filter, an air pump, a one-way valve, a pipeline, a wiring harness, a power source, a controller, a two-position two-way exhaust valve, a two-position three-way exhaust valve switch, a plurality of pressure sensors, a wheel speed sensor, a plurality of two-position two-way switch valves, an air storage tank, a plurality of air springs, a tire, a throttling valve and an adjustable throttling valve. The controller is respectively connected with the plurality of switch valves and the adjustable throttle valve, so that the switch valves and the adjustable throttle valve can be opened when the tire pressure is too high, and the tire pressure is stably reduced. The five switch valves are arranged, inflation and deflation are conducted through the compressor, and when the tire pressure is inconsistent or the wheel speed has deviation, the controller can control the air
