The earliest period of air springs were invented abroad in the fifty of the 19 th century, then the air springs replace the original elastic elements to be applied to vehicles, with the development of the vehicle industry, most of the rear suspensions of heavy trucks in developed countries adopt air suspension systems, and the research of the air suspension systems is started in the 50 th of the 20 th century, then the load-carrying vehicles with the air springs are developed, and then the air suspensions used on buses, buses and trains are successfully developed. Through continuous development of the air suspension, the technology is mature, the cost is gradually reduced, and the application rate in the field of commercial vehicles is gradually improved.
The air suspension is used as one of the vehicle suspensions, and mainly comprises an air spring, a guide mechanism, a front support, a shock absorber, a height control mechanism, an air compression device and the like, wherein the air suspension system uses the air spring as an elastic element, and the shock absorption effect is realized by utilizing the compressibility of air in an air spring air bag.
The air spring is used as an elastic element, the rigidity of the air spring is variable, the rigidity of the air spring increases with the increase of the load weight, in addition, the height of the air spring is adjustable, the air spring expands with the increase of the air pressure in the air bag, and compresses with the decrease of the air pressure, so that the height of the vehicle body is adjusted.
The popularization of the air suspension and the plate spring air bags has prompted the appearance of a trailer lifting air suspension, and the axle can be lifted or dropped through the inflation and deflation of the air bags. The vehicle axle can be lifted when not fully loaded, the abrasion of tires in running is reduced, and the misguidance caused by multi-axle running is eliminated, so that the oil consumption of the vehicle is reduced, and the vehicle axle falls down when fully loaded to participate in bearing together with the driving axle, so that the vehicle bearing requirement is met. Therefore, the structure can increase the bearing capacity of the vehicle and reduce the running loss of the vehicle, thereby creating economic benefits for users.
The existing trailer lifting air suspension guide arm is an integrated guide arm made of spring steel, the body is heavy in weight and poor in coordination, an air bag cannot be uniformly stressed, and the lifting guide arm support structure is complex, so that the total weight of the suspension is increased.
