Problems solved by technology

[0002] Rubber-tyred gantry cranes are often used to transfer containers in port yards. During the long-term loading and unloading of cranes, the following problems may be encountered: 1. The tire pressure will be insufficient after a period of use, and it needs to be shut down to inflate, which will affect the normal production of the terminal; 2. Insufficient tire pressure for a long time will lead to tire deformation, air leakage or even permanent damage, which will result in greater maintenance costs; 3. There is also the possibility of excessively inflating the tire pressure or uneven tire pressure during maintenance inflation; 4. The fluctuation of daily and seasonal temperature will also cause the tire pressure to fluctuate; 5. The reasonable working tire pressure state of the tire has an important impact on the operation safety
However, there are the following disadvantages: 1. The tire needs to be disassembled to be installed; 2. The cost of the large-diameter rotary air seal device is relatively high, and it is still difficult to popularize and apply it in large quantities; 3. The sensor is placed in the central controller, and it is impossible to monitor the tire in real time. When measuring the pressure, it is necessary to first inflate and open the tire valve, and then maintain the pressure to quickly drain the public pipeline, which will easily cause the tire pressure to become lower and lower, and the pressure measurement accuracy is not enough; Tire pressure monitoring system) is interconnected and cannot work independently, and it is easy to cause instability of the inflation and deflation system due to instability of the TPMS system

Abstract

The invention discloses a tire inflation and deflation system and a vehicle, and relates to the technical field of tire pressure control; the tire inflation and deflation system comprises at least one inflation and deflation unit, and each inflation and deflation unit comprises an air pump, an air pipe and a wheel side control valve assembly; the air pump is communicated with the tire through the air pipe and is used for inflating the tire; the wheel side control valve assembly comprises a wheel side ECU and a sensor for monitoring the tire pressure in real time; a one-way valve that is arranged on the air pipe; a deflation electromagnetic valve that is used for deflating the tire. The tire pressure monitoring device has the advantages that the tire pressure can be monitored in real time under the action of the sensor, so that the tire pressure can be adjusted in real time; wherein the components of the wheel side control valve assembly are arranged independently and can be disassembled and assembled independently, and the overhaul and maintenance cost is low.
