As we all know, the most important evaluation criterion for the quality of a trailer is its axle assembly. Trailers for different purposes will use different axle assemblies. For example, some commonly used axles are American and German. These two axles have different use characteristics.

German axle has good service performance and has very significant advantages:

1. The axle beam is not easy to bend, saves tires, and the bearing capacity of heavy load is more reasonable

2. The clearance between the bearing and the shaft head is matched, which has better lubrication effect and less resistance, so that it has good high-speed performance and oil saving

3. The S-type cam head design and the cylinder hole of the power chamber can be modulated to make its braking force greater, and the braking force of the front, middle and rear axles can be more reasonably distributed, and the braking force distribution is more reasonable.

The formula shoe used has large friction coefficient, high temperature resistance, better braking performance, and can operate freely for long-distance braking, which can shorten the braking distance.

Disadvantages:

1. The price is high and the one-time investment is large. The 13 ton bridge is about 2000 yuan more expensive than a Fuhua bridge.

2. Parts are hard to buy. German axle oil must be used for maintenance.

In China, BPW axles are mostly used in relatively high-end markets such as precision instrument transportation, tobacco transportation and hazardous chemical transportation, which require good stability.

Current advantages of American axle:

advantage:

1. High cost performance, low cost and low initial investment.

2. Reliability and service were also very good.

3. Good overload performance.

4. Large quantity and convenient maintenance.

Disadvantages:

1. High maintenance costs.

2. The braking effect is not as good as BPW, which costs tires.

According to comparison, American style is still the first choice for most people, but it also depends on your specific needs,

At present, there are only a few well-known manufacturers of trailer axles, axles and accessories in China. Shandong Liangshan, as the trailer capital, has also emerged a number of well-known enterprises. Here are some brands with good quality and cost performance.

1. Fuhua axle
