As we all know, the traditional trailer due to the existence of the axle, especially the plate-type and warehouse-type semi-trailer due to the restrictions on the height of the axle, and the restrictions on the loading space of the box-type trailer, the loading space has been greatly affected, which is to enhance the transport efficiency and reduce Logistics costs are very unfavorable, and a Yost LV-O independent air suspension that Xiaobian will introduce to you is the perfect solution to this problem.
Traditional air suspension
In conventional suspension, whether it is leaf spring suspension or air suspension, the floor of the cargo box must be located above the axle due to the existence of the axle tube between the wheels, even if the suspension system of the portal axle is adopted, the chassis space thereof The utilization rate will still be insufficient, and the presence of the axle will also affect the passing performance of the vehicle.
In terms of safety, the higher floor of the cargo box lifts the center of gravity of the vehicle when it is fully loaded, which greatly increases the probability of the vehicle rolling at high-speed cornering, thus affecting the safety of the vehicle. The Yost LV-O independent air suspension utilizes a unique structural design that eliminates the axle tube between the traditional wheels, reduces the vehicle's center of gravity, greatly reduces the roll of the vehicle and improves the safety of the vehicle. And because the trailer compartment sinks, in the event of a traffic accident with other vehicles, ordinary passenger vehicles will not enter the chassis of the vehicle, both from the side and rear of the vehicle, and do not install the rear end of the vehicle.
Yost independent air suspension
In our common air suspension, the airbags are mostly perpendicular to the ground. The advantage of this design is that when the vehicle encounters a pothole, the direction of force of the suspension system is consistent with the vibration direction of the airbag, and Yost's LV The -O independent air suspension is characterized by the airbags being transferred from between the wheels to the top of the tire. It is common to say that the suspension is in the same plane as the wheel, and a shock absorber is also installed between the airbag and the axial end of the hub.
When the vehicle encounters a pothole, the movable rubber bearing is fitted with a shock absorber to transmit the vibration perpendicular to the ground to the hanging airbag above the tire. In fact, this design is more similar to the push rod suspension, in other words, the suspension is changed. The force direction of the system leaves the space originally belonging to the axle and suspension to the cabinet, which improves the space utilization.

In addition, Mr. Frans Lipman, president of TRACE brand of Yost, told China Truck.com that due to the limited capacity of the box truck, the loading space of the container was affected, and the Yost LV-O independent air suspension has The lower floor height of cargo containers can still ensure that the vertical height of each cargo space is more than 1.8 meters in the case of a double-decker compartment design, so as to ensure cargo carrying capacity, which is to improve transportation efficiency and promote cost reduction and efficiency increase. Modern logistics is of great help. In addition, because the floor of the container sinks, loading and unloading of the vehicle becomes very easy.
With the new version of GB7258 "Safety Requirements for Motor Vehicle Operation", the provisions for air suspension shall be provided for dangerous goods transport semi-trailers, three-axis fences, and silo-type semi-trailers with a total mass equal to or greater than 12,000 kg. The popularity of the field will be greatly increased. This is both a challenge and an opportunity for OEMs and special vehicle manufacturers.
