At present, the production process and technology of trailer axles in China are basically the same, and the axle models of each manufacturer are different,

According to the structural design of the axle, it is divided into American and German. The axle head of the American axle looks stronger than that of the German axle, so the American 13T axle is the best-selling one in the market. American axle maintenance is cheap and can pull heavy loads, so it is more popular with trailer drivers. The structural design of German axle is relatively stable and suitable for the transportation of some precision goods. Therefore, drivers of general tank cars, express, cold chain and van trailers prefer German axle.

Now it is basically distinguished according to the rated load tonnage of the axle. For example, Darong axle RSC series has axles of different tonnage such as 8t, 10t, 11T, 12t, 13T, 15t, 16t, 18t, 20t and 25t, and its raw material selection, treatment process and assembly process are basically the same.

At present, domestic trailer axle manufacturers are divided into the northern camp and the southern camp. The northern camp is represented by Darong axle and the southern camp is represented by Fuhua axle and BPW axle.

Darong axle:

Darong machinery has built a 100000 ㎡ standard chemical plant, laid the industry-leading high-precision automatic intelligent production line, and carried out all production work in strict accordance with iatf16949 international standard. The company has set up a special quality inspection team to check the product quality at all levels. At the same time, it has set up a finished product test workshop to conduct extreme tests on various properties such as product strength, stiffness and wear resistance, so as to ensure that the quality of finished products is strictly up to standard. The company has an annual output of more than 170000 trailer axles, axles and trailer accessories. Its sales network covers the whole country and radiates more than 50 countries and regions around the world.

BPW axle:

It is a Sino foreign joint venture controlled by German BPW company, mainly producing and operating BPW rigid suspension axle, air suspension axle and axle related parts of various specifications and models. The company covers an area of about 170000 square meters and has advanced flash butt welding equipment, high-precision CNC processing equipment and perfect testing equipment. With the rapid development of China's automobile industry, the company continues to grow and grow. It has been ranked in the forefront of domestic peers for many years in terms of brand, technology, R & D, quality and service. It is a benchmark enterprise of domestic peers.

Fuhua axle:

Guangdong Fuhua machinery group was founded in 1997. Since its establishment, the group has always adhered to people-oriented, quality first, independent innovation, continuous improvement and the policy of technological innovation and development. Most of the group's main products have independent intellectual property rights, covering semi-trailer bridges, truck bridges, engineering bridges, containers, refrigerated containers, suspension systems, outriggers, saddles, braking systems and other products. It has become a respected, respected and trusted manufacturer of special parts for road vehicles in the mainstream market.

In terms of the current market situation, American disc brake bridges are highly praised by drivers. On the one hand, at present, the state forces three-axle rail cars and warehouse grid cars to use disc brakes and air suspension. As the main force of domestic highway transportation, three-axle trailers must implement national policies.

At present, the manufacturing process of axle has tended to be consistent. According to the market demand, the price is greater than the premium capacity of brand manufacturers. Now the prices of Fuhua axle and BPW axle are generally more expensive, so the first choice for most drivers is manufacturers with very high cost performance such as Darong axle.
