Applications
A semi-trailer suspension is an important part connecting the traveling device and the frame of the semi-trailer.
All forces are all transmitted through the suspension system. And the suspension reduces the impact of harsh roads on the vehicle, plays a shock absorption effect, and improves the ride comfort of the vehicle.
Semi-trailer suspensions are widely applied to skeletal trailers, lowbed trailers, flatbed trailers, dump trailers, car transport trailers, oil tank trailers, van trailers, full trailers, wood transport trailers, agricultrucal vehicles, etc. Classification of suspension indlude German series suspensions, American series suspensions, bogie/boogie suspension series, air suspension series, rigid suspension series, YORK suspensions, ROR suspensions, HENRED suspensions, semi-trailer suspensions, trailer suspensions and agricultural series, etc.
Air suspension refers to the suspension using air shock absorbers, mainly through the air pump to adjust the air volume and pressure of the air shock absorber, which can change the hardness and elastic coefficient of the air shock absorber. By adjusting the amount of air pumped in, the stroke and length of the air shock absorber can be adjusted, and the chassis can be raised or lowered. The air suspension system is a very advanced and practical configuration. It uses the increased rigidity of the enclosed gas in the air spring after being compressed, that is, as the air spring is continuously compressed, its stiffness gradually increases, and at the same time, the internal gas follows the air spring. Being compressed or elongated and pressed in or out, the air suspension system has close to ideal dynamic elastic characteristics. In a broad sense, air suspension is a suspension that uses air springs as elastic elements.

Products and logistics of WONDEE Autoparts semi trailer air suspensions:Compared with the traditional leaf spring suspension system, air suspension has many advantages:
First, light weight. The biggest advantage of air suspension is its light weight, which is much lighter than traditional leaf spring suspension.
Second, it is convenient for loading and unloading. Through the manual height valve in the air suspension system, the height of the vehicle loading platform can be adjusted within a certain range to facilitate loading and unloading of goods.
Third, the driving is stable and the shock absorption performance is good. Compared with lightweight vehicles, vehicles with air suspension travel more smoothly.
Fourth, high security. The uniform distribution of the axle load and the balanced contact between the tire and the ground can improve the overall braking performance and turning stability of the axle. At the same time, the height of the air spring can be automatically adjusted according to the road conditions to reduce vibration and help protect the safety of goods.
Fifth, reduce maintenance costs. When the vehicle is running with no load, the air suspension can lift the axle, reduce tire wear, extend the service life, and reduce fuel consumption at the same time.
