The axle is one of the key load-bearing components of a vehicle, which is connected to the body through suspension at the top and used to install wheels at both ends. It can not only support the weight of the body but also maintain the normal driving of the vehicle on the road.
The axle can be integral in shape, resembling a large barbell, or it can be disconnected, like two umbrellas inserted on both sides of the vehicle. According to the different driving methods, the axle can also be divided into drive axle, steering axle, steering drive axle, and support axle.
In general, whether it is a semi trailer, a full trailer, or a center axle trailer, its function is to provide cargo loading space. In most cases, it does not have driving power and needs to rely on the power of the tractor to achieve driving. Therefore, most of the axles on the trailer do not need to have driving power and belong to the supporting axle, which can also be called a driven axle.

The support bridge is a type of integral axle, mainly composed of components such as axle beams, camshafts, metal support seats, brake assemblies, wheel end assemblies, etc. The structural design is relatively simple. The integrated axle beams can provide greater bearing and torque, and are often used in conjunction with non independent suspension to meet the transportation needs of vehicles. Daily maintenance and upkeep are also more convenient, suitable for car owners who require high vehicle attendance.



Although the trailer axle belongs to the support axle, its models and specifications are very diverse, which is also to meet the usage needs of different transportation conditions. In general, the common types of trailer axles include the following:

The disc axle was previously mostly used in passenger cars. After the update of GB7258, it is required that all three axle railings and semi trailers must use disc brakes.

The biggest characteristics of a disc axle are its light weight, fast heat dissipation, fast braking response, good linear stability, strong resistance to thermal and water attenuation. However, its disadvantage is that the braking force is relatively small, which is not suitable for heavy cargo transportation. Some transportation conditions that require high protection of goods, such as hazardous chemicals transportation, precision instrument transportation, precious goods transportation, vegetables, fruits, and flowers transportation, are suitable for using disc type axles.

Drum type axle is the most familiar axle for freight car owners, and it is also the most widely used type on trailers. It can be almost used in transportation conditions for various types of goods with low requirements for cargo damage. Its technical conditions are relatively mature, and the selling price is cheaper. In addition, its accessories are universal, easy to buy and replace, and maintenance is also relatively convenient.

The drum axle is equipped with a sealed brake drum, which can provide more sufficient braking force. However, the disadvantage is that the heat and water attenuation are more obvious, and the stability is not as good as the disc axle. In general, drum axles are particularly suitable for the transportation of heavy goods, such as coal, wood, gravel, steel, cement, etc.







Low platform vehicle bridge is a special vehicle bridge for large platform vehicles, characterized by low ground clearance, low center of gravity, high wall thickness, and high strength. It can provide sufficient support, improve transportation stability, and enhance the convenience of loading and unloading goods. It is generally used for the transportation of large and non detachable goods such as mechanical equipment, large tanks, building materials equipment, and power station equipment.

The concave axle, also known as the eccentric axle, as the name suggests, its axle beam and wheel end center are not on the same horizontal line. Through the inverted door shaped design, the vehicle chassis height is further lowered.

The concave axle also reduces the height of the carriage to a certain extent, which can increase the loading space of the cargo compartment within the scope of regulations. It is mostly used on car transport vehicles, and some models with requirements for the center of gravity of the vehicle can also be applied. The disadvantage is that the vehicle's ability to cope with complex road conditions is poor, especially on uneven road sections, which are prone to bumping the chassis and have high requirements for transportation road conditions.

The three line six axle axle axle is a type of axle specifically designed for large or extra large transportation vehicles, with a super strong load-bearing capacity of around 80t. If it is a four line eight axle or five line ten axle model, the load-bearing capacity is stronger, even reaching hundreds or even hundreds of tons.



One of the most obvious characteristics of a multi axis axle is its large number of wheels and small volume, which can reduce the average pressure at the contact point between the tire and the road surface, and reduce or avoid road damage.


Light vehicle bridges refer to support bridges with a tonnage of less than 10t, commonly used in fields such as farms, residences, and field operations, such as 9t, 8t, 6t, 5t, 3t, and 1.5t. They are mainly used in transportation vehicles such as station transport vehicles, luggage transport vehicles, grain transport vehicles, fertilizer trucks, grass pickup vehicles, trailer trailers, camping vehicles, electric equipment trailers, yacht trailers, motorcycle trailers, etc. Their common feature is that the tonnage is relatively light, There are various top designs and different functions provided, resulting in many differences in production parameters and a small number of accessories. Therefore, in production, there is a tendency towards customized production.










The company has been specializing in the research and development and manufacturing of axles for over 20 years, achieving fruitful results in fields such as high load-bearing axle rods, lightweight axles, and customized production. The products are diversified and have been exported to countries such as Europe, the Americas, and Australia multiple times.
