The invention provides an automatic constant pressure device for a hub tire system. The device comprises a valve nozzle, air pipes, valves, a pneumatic slip ring, a hub, a pressure relief valve, a tire, a main shaft, an air storage tank, a vehicle-mounted air source and the like. Two valve holes are machined in the hub of the device. The valve nozzle with a tire pressure sensor is installed at one valve hole, and the pressure relief valve is installed at the other valve hole. The tire pressure is detected by the tire pressure sensor. The valve is controlled to inflate through the valve nozzle, and the pressure relief valve is controlled to relieve the pressure. The device has the characteristics of scientific detection principle, simple and reasonable structure and the like.
