Description

Technical Field

[0001] The utility model relates to the technical field of inflation equipment, in particular to an accompanying air suspension inflation equipment. Background Art

[0002] As the technology of air suspension becomes more and more mature, it is applied to more vehicles. At present, the air suspension system of vehicles is mostly inflated by the vehicle's own air pump or by manual inflation. The inert gas in the gas cylinder is also used to inflate the vehicle's air suspension. When the vehicle's own air pump is used to inflate the vehicle suspension, the vehicle suspension can only be inflated after the vehicle is assembled off the line, which increases the difficulty of assembly on the production line; when the vehicle suspension is inflated by manual inflation, there are certain requirements for the pressure of the gas cylinder, and the inert gas used is relatively expensive, the requirements for operation are also relatively high, it is not convenient to adjust, and the inflation efficiency is low; and the manual inflation method is not convenient for real-time monitoring of the inflation quality. It can be simply applied during trial production, but it is not conducive to mass production operations on the automobile assembly line.

[0003] For this purpose, online inflation equipment has also been developed. For example, the Chinese patent document with the authorization announcement number CN 211519169 U discloses a vehicle air suspension auxiliary inflation device, which realizes the inflation of the vehicle body after pressurizing the compressed air with a booster pump by setting an air filter device, an air drying device, a booster pump, an accumulator, a pressure reducing device, a filling valve, a pressure stabilizing system, a wall filling valve and a filling gun, which greatly improves the inflation efficiency. However, this technical solution still has defects. The equipment is a fixed device set beside the production line, which is not conducive to the high-beat production operation of the automobile production line. In addition, in order to meet the production beat requirements, the filling gun must be removed as soon as possible after the air suspension system is inflated to the rated pressure, so that the car flows to the next station. It is impossible to perform a certain period of pressure maintenance test on the air tightness of the air suspension system, and it is impossible to timely discover the possible leakage defects of the air suspension system.
