Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a filling equipment for an automobile air suspension system. Background Art

[0002] As far as cars are concerned, suspension plays an important role in the chassis of cars. It also affects the handling stability and comfort of cars. However, the above two performances are contradictory. As far as general suspension systems are concerned, vehicles with good handling stability will have poor comfort. In order to solve the above contradictions, air suspension came into being. Air suspension can adjust the damping and stiffness of the suspension in real time according to the running state of the car and the road conditions, so that the suspension system is always in the best shock-absorbing state, thus making the vehicle take into account both handling stability and comfort. When the whole vehicle is manufactured on the production line, because the air pressure in the air spring and the air tank is very low, it is not enough to support the weight of the car itself. Therefore, before the car lands, a certain amount of compressed air needs to be filled into the air suspension to make the vehicle land. When using the vehicle's own air pump to inflate the car suspension, the car suspension can only be inflated after the car rolls off the assembly line, which increases the difficulty of assembly on the production line; when using the manual inflation method to inflate the car suspension, the pressure requirements or operation requirements of the gas cylinder are relatively high, it is not convenient to adjust, and the inflation efficiency is low; the manual inflation method is not convenient for monitoring the inflation quality, which can be simply applied during trial production, but is not conducive to operation on the automobile assembly line.
