The suspension axle of a heavy truck, also commonly known as a "lift axle," is an axle that can be lifted freely. After being lifted, the axle tires can be lifted off the ground. The suspension axle is generally an auxiliary axle without driving force. The tractor-assisted lifting axle has good economic advantages. When it is heavily loaded, it can be lowered to carry the weight and effectively improve the vehicle's shock absorption. When it is unloaded, it can lift the axle. There is no friction resistance between the tires of the suspended bridge and the ground. It can effectively reduce vehicle fuel consumption and reduce tire wear.
Suspension bridges can be divided into pneumatic, hydraulic, electric and other forms according to different lifting systems. In addition, suspension bridge technology can be divided into the following forms: middle suspension bridge, rear suspension bridge, and the load-bearing part includes traditional steel plate suspension and more advanced airbag suspension. The common tractor lift axle is only a load-bearing bridge. There is no drive gear structure, which makes it lighter and easier to maintain. Although the impact of road conditions on vehicle driving can be reduced through adjustment of its own lifting function or advanced electronic assistance systems, it is still quite different from the dual-linked drive axle form. After all, it is a lifting axle without drive.
The principle of lifting the suspension bridge: The entire system consists of an air storage cylinder, an air bag, a solenoid valve, two load transfer devices, and two quick release valves. By inflating the air bag, the leaf spring is pressed down, and the two outer bridges are lifted. When the vehicle brakes, the airbag is deflated and the two axles are lowered to the ground. However, due to the high price of lifting airbag suspension, domestic users are more price-conscious.
Trucks are pontoons, which have a long history in both developed and economically developed countries. They have relatively mature experience in vehicle stability and lightweight design, and have been fully verified in developed countries in Europe and the United States. The application is extremely wide. Such as the current Mercedes-Benz 2644 tractor, Xianen TGS tractor, Scania R470 tractor, Volvo FM400 tractor and other world-famous trucks.
In the middle of the last century, our country designed a prototype suspension bridge for an 8-ton heavy-duty truck by installing auxiliary wheels on a medium-sized truck. After mass production, it greatly satisfied the market demand for heavy-duty vehicles at that time. So far, such quasi-suspended bridge design is still used in medium-sized special-purpose vehicles or special-purpose vehicles. However, as my country's economy entered the mid-to-late 1990s when China's economy was growing rapidly, some users began to illegally modify and exploit loopholes in order to cope with policies and regulations. Many vehicles that did not have the load-bearing function of suspended bridges became popular.
In 2004, after the promulgation of China's "Highway Law", the country began to vigorously control "overloading and overloading". This was also an era when some heavy truck companies launched various types of suspension material series products and were widely used, especially the launch of China National Heavy Duty Truck Its suspension bridge series has more models, more mature products and is more popular in the market.
