Disc brake, also known as disc brake, consists of a brake disc connected to the wheel and a brake caliper at the edge of the disc. When braking, the high-pressure brake oil pushes the brake pad to clamp the brake disc, resulting in braking effect. Due to its sensitive braking response and good heat dissipation performance, it has been widely used in passenger cars in the past. With the introduction and implementation of gb7258-2017, the application scope of disc brake bridge will be wider and wider.

The axle is different from other parts of the vehicle. Once it fails during transportation, the vehicle will be unable to drive. For car owners, it will not only affect the delivery time and reduce the freight, but also affect the trust of customers and lead to a series of difficulties in subsequent cooperation. Moreover, the quality of the axle directly affects the safety. Imagine that if a high-speed transport vehicle suddenly breaks the axle, it will be a dangerous thing for both owners and passers-by. It can be seen how important it is to choose a reliable axle.

At present, there are many domestic manufacturers of axles, but only a few really do well. Here is a brief inventory of several well-known brands of disc brake semi-trailer axle:

1. Guangdong Fuhua. It is a representative brand of American axle. Its main products include semi-trailer bridge, truck bridge, engineering bridge, container, refrigerated container, outrigger, suspension system, saddle, braking system, etc. At present, the American axle produced by Fuhua accounts for about 60% of the domestic market, and the quality is reliable. Of course, as a representative brand in the axle industry, there is also a certain brand premium in terms of price. Products of the same specification are about one to two thousand yuan higher than other brands.

2. BPW (Meizhou), the representative brand of German axle, is a Sino foreign joint venture controlled by German BPW company. Its products cover rigid suspension axle, air suspension axle and axle related parts. It mainly takes the high-end route, and the price naturally remains high. Generally, it can be about 2000 yuan higher than Guangdong Fuhua.

3. Darong group. The representative of domestic old axles mainly produces and operates all kinds of trailer axles, axle assemblies, special axles and axle related accessories, including American and German axles. Darong group is the first axle R & D manufacturer stationed in Liangshan quanpu industrial park more than 20 years ago. Its technology and strength are at the forefront of the industry. Its price is more popular than Guangdong Fuhua and BPW (Meizhou), but it is relatively low-key in publicity. At present, its customers are still mainly introduced. It has high credibility and good reputation in most teams and car owners.

4. Fengbao Heavy Industry Co., Ltd. An emerging brand in the axle industry, located in Linzhou City, Henan Province, it mainly manufactures commercial trailer axle assemblies and their parts. Compared with other brands, Fengbao Heavy Industry Co., Ltd. was established later, but it has its own channel advantages in raw materials. Therefore, the price of its axle is almost the lowest in the same industry, mainly developing large customers. In terms of quality, further feedback from the market is needed, but no opposition has been heard at present.

This still needs to be analyzed in detail. On the one hand, it depends on the vehicle model, type of goods transported, transportation route, road conditions and other factors. On the other hand, it is to consider the economic conditions of the owner. If the owner's supply of goods is relatively stable, the price of one trip is relatively high, and he doesn't pay special attention to the cost, he can directly choose big brand products. Although the price is high and the maintenance is expensive, the quality can at least be guaranteed. If car owners are more concerned about the cost and feel that they can't make ends meet by spending 6000 or 7000 yuan on the axle, there are also brands with good quality and low price to choose from. For example, the axle produced by Darong group mentioned above, although the price is popular, the quality is not inferior to the big brand at all. Whether it is bearing capacity, maintenance cost, stability or braking efficiency, it is no worse than the big brand, The cost performance is quite high.
