They are used to load different goods respectively. Semi trailers of different structures are loaded with different goods and cannot be mixed.

Traction pin, which is the connection between the semi-trailer and the tractor, and bears the traction force to drive the front of the semi-trailer.

4. Suspension system of a semi trailer

Suspension system is a device used to connect the frame and the axle, mainly used to support the load and slow down the impact of the dynamic load of the vehicle and cargo, generally can be divided into steel plate suspension, single point suspension, air suspension, rigid suspension There are four types, and there are differences in performance, which need to be selected according to the purpose of the vehicle.

The running mechanism of a semi trailer mainly refers to the axle system, steel ring and tires. Its main function is to bear the weight and maintain the running of the vehicle, and to support and distribute the load between the frame and the wheels. The axles and tires we produce are currently the most cost-effective in the Chinese market. They are reliable in quality and inexpensive, and are most popular with users. Welcome customers to come to negotiate business.

The semi-trailer axle, also known as the axle assembly, is mainly used to bear weight and maintain the normal driving of the semi-trailer on the road. Carrying capacity etc. play an important role. Our axles support customization and can meet the needs of customers to the greatest extent.

The tires are in contact with the road surface and bear the weight of the car. Together with the suspension of the semi-trailer, they play a role in easing the impact. The tires and the road maintain good adhesion and improve the traction, braking and passability of the semi-trailer. If a semi-trailer is not supported by wear-resistant, heat-resistant and durable tires, its safety performance and economic benefits are out of the question. So the choice of tires is also extremely important. Tires are rubber products. In addition to wear and tear, they will naturally age. You also need to pay attention to the maintenance and inspection of tires, clean up debris in time, and replace them in time if they are found to be aging.

If the axle is not selected properly, it will directly affect the safe use of the vehicle. We provide our customers with quality axles.

The steel ring is also called the wheel hub, which refers to the drum-shaped, barrel-shaped part that supports the tire inside the tire, and the center is mounted on the axle. It is an important part of the semi-trailer. The driving process of the semi-trailer will generate lateral and longitudinal loads, accompanied by driving torque and braking torque. Therefore, the hub needs to bear a considerable part of the load. high. In order to meet the market demand, the steel rings launched by many manufacturers have been improved, such as the design of the sealing structure, the simplification of the maintenance process, and the extension of the maintenance cycle. Customers can choose according to their needs when purchasing.

Protective devices have also become an essential part of the semi-trailer. The current semi-trailer will be equipped with a protective net. Due to the large blind spot of the semi-trailer, when someone is knocked down by the protective net when turning, the driver is not easy to find, which may cause serious consequences.
