Resistant to heavy loads American Type Leaf spring trailer suspension-manufacture,factory,supplier from China

Trailer "tire eating" is a popular term for abnormal tire wear. As the only part of the vehicle that is directly in contact with the road, tires need to bear various deformations, loads, forces, and high and low temperature effects under high-speed, heavy load, rain, snow, sand and gravel conditions.

To say which type of vehicle is the hottest in the current heavy truck market, I am afraid to be the LNG gas heavy truck.According to relevant data, the cumulative sales of heavy trucks from January to July 2023 were 361,900 units, an increase of 25.2% over the same period last year of 289,000 units, of which the cumulative sales of 63,800 gas heavy trucks were 24,400 units over the same period last year, a jump of 161%, in the off-season of heavy truck sales in July and August of previous years, the gas vehicle market is still hot.

With the development of transportation environment, transportation level and modern logistics industry, the demand for heavy trailers in road transportation is also increasing.

Air suspension is currently common in two types of structures, namely European suspension, American suspension, let us understand how they are different.● The two environments derive different trailer suspension structuresBefore saying two kinds of air bag suspension structure, let's talk about the transportation environment in the United States and Europe, the difference between the two transportation environments, the formation of two kinds of suspension structure.

Leaf spring is one of the most widely used elastic components of automobile suspension, also known as leaf spring, composed of a number of pieces of equal width and unequal length alloy spring, generally presents a symmetrical section structure, the thickness of each spring can be the same or different.Compared with other types of elastic components, the leaf spring structure is simple, low cost and maintenance costs, strong rigidity, load-bearing, not only can play the role of shock buffering, but also has the function of guidance, transmission of force and torque in all directions, but also

Suspension is a connection device between the axle and the frame, which is used to transmit force and torque, reduce the impact of the road surface on the body, reduce the body vibration caused by the road surface fluctuation, and ensure the smooth running of the vehicle.Although the spring suspension is not as good as the air suspension in terms of shock absorption performance and self-weight, it has simple structure, low cost and maintenance cost, strong rigidity and high load-bearing force.Moreover, the leaf spring has a guiding function, can transmit the force and torque in all directions,

Suspension is a connection device between the axle and the frame, which is used to transmit force and torque, reduce the impact of the road surface on the body, reduce the body vibration caused by the road surface fluctuation, and ensure the smooth running of the vehicle.At present, the common suspensions in the commercial vehicle market are mainly leaf spring suspension and air suspension. Although the call for air suspension has become more and more popular in recent years, it is still difficult to shake the market application rate of 80% of leaf spring suspension.

Since the introduction of GB7258 "Technical Conditions for Motor Vehicle Operation Safety", air suspensions have been installed more and more frequently on three-axis fence-type and warehouse-type semi-trailers. Compared with the traditional leaf spring suspension, the air suspension has light weight and good weight reduction effect. While improving the ride comfort of the vehicle, it can also realize free lifting of single or multiple bridges.

The trailer loads a lot of weight and has a strong inertial effect, and the pressure on its braking system is relatively high, especially in the face of long downhill or rugged mountain roads that require frequent braking If the pressure is high, it will become hot and hot.

The trailer rear axle is a typical driven bridge, also known as the support bridge, does not have driving and steering functions, the structure is simpler than the steering bridge or the drive axle, and is connected to the frame through the suspension system, which plays the role of load-bearing, braking, shock absorption, and maintaining the driving.The trailer rear axle can be divided into a number of types according to different classification methods, such as drum type and disc type, light weight type and heavy load type, ordinary type and maintenance-free type, American type and German ty
