On November 4, 2017, a globally unique trailer suspension debuted at the Wuhan Auto Show. If the vehicle is compared to humans, then the body is unstable and only the suspension knows. The excellent soft hydraulic air suspension is a brand-new technological innovation. In order to better understand the new soft products, the China Truck Network reporter went deep into the Wuhan Auto Show to get a closer look at the hydraulic air suspension.

What is the reason why the hydraulic air suspension comes from? What is the advantage compared to the ordinary suspension? Is it a gimmick or a definite name? How can a brand-new suspension bring us benefits?

Military air suspension on military background

Before the auto show, the China Truck Network reporter learned that after a lot of understanding, hydraulic air suspension is the suspension of oil and gas, and its technology has long since matured, but it has not been able to meet with everyone. Hydraulic air suspensions have been used by the state for a long time, and they have appeared on aircrafts and tanks to improve stability. It can be said that the hydraulic air suspension technology was the first time that it appeared in the commercial vehicle exhibition. The quality of military engineers could not help but cast a mysterious disguise on the hydraulic air suspension. For this purpose, we specially interviewed You Qijun, director of Yousoft Marketing, and listened to him for an in-depth explanation of the hydraulic air suspension.

Innovative design allows prices to drop in quality

Zhao Jun told China Truck Network reporter: “The application of hydraulic air suspension on semi-trailer is the first of excellent soft company. Why the oil-gas suspension can not be used on the trailer for a long time, because the hydraulic air suspension is such a fine equipment. The price has remained high, but Yousoft has innovatively solved this problem during the R&D process, adopting a double-chamber design, allowing two air chambers and one high-pressure chamber in one linkage of the hydraulic air suspension. One is the low-pressure gas chamber, which not only enables the vehicle to run stably under heavy loads and no-load conditions, but also significantly improves the suspension performance while at the same time effectively controlling the cost. Zhao Qijun proudly stated that foreign experts must find us to communicate and learn. This technology is also unique in the international community.

Soft cushioning makes the chassis more stable and safer to drive

Hydraulic air suspension is not unreasonable for foreign experts, and its excellent performance is an important reason it attracts a lot of attention. The suspension is like the vehicle's spirit level and buffer during the movement of the vehicle. The difference between a hydraulic air suspension and a normal suspension is that it is a soft buffer. While braking and braking, the center of gravity of the vehicle can be reduced to increase the friction between the tire and the ground, and the braking distance can be shortened by about 5M. Makes the vehicle brake safer and more efficient.

Cardmates all know that the truck will tilt during the turn, overdrive or even overturn. The excellent buffering capacity of the hydraulic air suspension perfectly solves this problem and allows the vehicle to remain as smooth as possible when cornering. Not only that its damping ability can also reduce the shaking and impact of the brakes in the cab when jumping up, which makes driving easier, effectively reducing driver fatigue and preventing occupational diseases.

Lighter weight and efficient and economic coexistence

Zhao Jun also told China Truck Network reporter: "Because the hydraulic air suspension is based on nitrogen as the elastic medium, oil as the transmission medium, so the volume is very small and compared to the leaf spring to be light and half the contrast torsion spring light 20% and The effect is better. "The reduction in weight represents a reduction in weight, allowing you to run faster and further with less oil."

The advantages of the hydraulic air suspension are not only that, the suspension keeps the tire in perfect contact with the ground, so that each part of the power is directly transmitted to the ground to make driving more efficient. Hydraulic air suspensions have a smaller dynamic load factor than other suspensions. Hydraulic air suspension is more stable during driving. Undoubtedly, it is another layer of protection for dangerous goods transportation and valuable goods logistics. Excellent buffering capacity can reduce the impact on vehicle parts during driving, effectively prevent parts from being damaged, reduce vehicle maintenance costs, improve attendance, and ultimately maximize customer benefits.

According to the new GB7258 "Motor Vehicle Operational Safety Technical Conditions," the introduction of this new standard has opened up a new horizon for the suspension market. The excellent soft hydraulic air suspension will make up for the existence of vacancies in the truck's oil and gas suspension and will occupy a major market in this field.
