Abstract

The invention discloses an air suspension system of a light trailer. The shock absorber comprises left and right plate spring bracket assemblies, left and right upper shock absorber pin shafts, left and right upper guide beam assembly, left and right U-bolts, left and right airbag lower brackets, left and right bearing airbag assemblies, left and right airbag cover plates, left and right shock absorber bracket assemblies, left and right lower shock absorber pin shafts, left and right shock absorber assemblies and left and right sleeves, the left plate spring support assembly and the right plate spring support assembly are fixedly welded with the left air bag support and the right air bag support, and the left shock absorber support assembly and the right shock absorber support assembly arefixedly welded on an axle. The air suspension system can effectively absorb vibration generated when a vehicle runs, transported objects are protected, and the air suspension system is particularly suitable for precise instruments and hazardous chemical substance transport vehicles.

Description

technical field [0001] The invention relates to the technical field of trailer air suspension, in particular to an air suspension system of a light trailer. Background technique [0002] Due to the compressibility of the gas in the air spring, not only the air suspension system is easy to obtain excellent nonlinear stiffness characteristics, but also the height of the vehicle body can be adjusted according to the needs, so it is more and more widely used in vehicles. Suspension system is the connecting device of all force or moment between the frame of the car and the axle or wheels, and its fatigue performance is very important to the safety performance of the whole vehicle. [0003] The existing domestic trailer air suspension system has a complex structure and large mass, poor ride comfort and unsprung mass of the trailer, which cannot adapt to the development of lightweight trailers, and cannot take into account the comfort and handling stability of the entire vehicle at...
