Since the promulgation and implementation of technical conditions for safety of motor vehicles gb7258-2017 in 2020, the market demand of domestic disc axle has increased significantly.

Compared with traditional drum brake, disc brake has obvious advantages in sensitivity, heat dissipation, heat recession resistance and performance recovery after wading. When used in combination with air suspension and hydraulic retarder, it can greatly improve the safety and stability of vehicles and goods. It is also because of this that the popularity of disc axle is very high in Europe, America and other countries where the trailer industry developed earlier.

In contrast, in the domestic market, disc brake has been applied to the commercial vehicle industry in recent years. Before, it was mostly used in passenger cars. Therefore, compared with other types of axles, the trailer disc axle is still a relatively new product in the industry.

So, how much is the price of disc axle in China?

According to the survey, at present, the price of domestic disc axle mainly shows a polarization trend. The high price can be sold for 9000-12000 yuan and the low price can be as low as 3000-4000 yuan. The price difference is quite obvious.

The reason is not difficult to understand. The reason why some first-line brands sell at high prices is that in addition to reliable quality and advanced technology, the most important thing is the brand premium. Even if the same quality and technology are pasted with the brand logo, the price will directly double. Moreover, the so-called "wool comes from sheep", usually a large amount of advertising expenses, I'm afraid consumers will have to pay in the end.

If a single disc axle is 9000 yuan, if a trailer needs three axles, the cost of buying the axle alone will be close to 30000 yuan, which is still a little high for ordinary car owners.

On the contrary, there are those axles that sell very cheap. Although the price is very attractive, the quality is not guaranteed.

Let's think carefully. What is the role of the axle? Load bearing, braking and driving support are related to the core functions of the trailer and are closely related to driving safety. To produce a qualified axle, it is not only necessary to cut, weld and assemble raw materials, but also need to be processed through a series of processes such as heat treatment, quenching, tempering, sand blasting, straightening, precision grinding and medium frequency treatment, so as to stimulate the comprehensive mechanical properties of raw materials to the greatest extent. The finer the production process, the higher the product safety performance, The combined cost of these production processes alone is probably more than two or three thousand yuan, not to mention raw materials, quality inspection, wheels, bearings and various parts.

Therefore, buying a car bridge can not simply look at the price. Quality and performance are more important. Darong disc axle is a product of Darong heavy industry group. It entered the market for the first time in 2018. After many updates and iterations, it has the characteristics of light weight, strong bearing capacity, fast heat dissipation, convenient maintenance and long maintenance cycle.

In terms of raw materials, Darong axle selects lightweight materials and accessories, which are produced through 15 processes, such as raw material cutting, hot rotary rolling, high-precision shaft tube forming, full-automatic medium frequency quenching, integrated shaft tube heat treatment, sand blasting and derusting, on-line straightening, CNC precision grinding, medium frequency induction treatment, automatic gas shielded welding, etc The fatigue resistance and other properties are fully up to standard. In terms of price, Darong insists on making profits at low prices. Although the production process and product quality are not inferior to first-line brands, the average price of each axle can be about 30% cheaper. It can not only provide safe use guarantee, but also reduce the vehicle cost of vehicle owners, which has been widely praised by users at home and abroad.
