The invention particularly relates to a central inflation and deflation system for a vehicle. The central inflation and deflation system comprises an air source; the control valve module comprises an air source valve and a back pressure valve group which are arranged in parallel, and a wheel position valve which is connected with the air source valve and the back pressure valve group in series, and the air source is sequentially connected with the air source valve and the wheel position valve through an inflation pipe; the wheel assembly comprises a wheel and a wheel side valve, and the wheel position valve is sequentially connected with the wheel side valve and the wheel through a communicating pipe; the back pressure valve set comprises a back pressure valve and an exhaust valve, the wheel position valve is sequentially connected with the back pressure valve and the exhaust valve through an exhaust pipe, and the back pressure value of the back pressure valve is not lower than the opening pressure value of the wheel side valve. According to the central inflation and deflation system of the vehicle, the air pressure value in the communicating pipe can be maintained to be larger than the opening pressure value of the wheel side valve through the back pressure valve, so that air in wheels can be exhausted through the wheel side valve, the communicating pipe, the wheel position valve, the exhaust pipe, the back pressure valve and the exhaust valve, and the purpose of adjusting the tire pressure of the vehicle is achieved; and the complexity of the control valve module is reduced.

    本申请具体涉及一种车辆的中央充放气系统,包括:气源;控制阀模块,包括并联设置的气源阀和背压阀组,以及与气源阀和背压阀组串联的轮位阀,气源通过充气管依次与气源阀和轮位阀连接;车轮组件,车轮组件包括车轮和轮边阀,轮位阀通过连通管依次与轮边阀和车轮连接;背压阀组包括背压阀和排气阀,轮位阀通过排气管依次连接背压阀和排气阀,背压阀的背压值不低于轮边阀的开启压力值。本申请提出的车辆的中央充放气系统能够通过背压阀使连通管内的气压值维持在大于轮边阀的开启压力值的状态,从而使车轮内的气体能够通过轮边阀、连通管、轮位阀、排气管、背压阀和排气阀排出,以此达到调节车轮胎压的目的,降低了控制阀模块的复杂性。
