Trailer axle choose German or American?

The trailer rear axle is a typical driven bridge, also known as the support bridge, does not have driving and steering functions, the structure is simpler than the steering bridge or the drive axle, and is connected to the frame through the suspension system, which plays the role of load-bearing, braking, shock absorption, and maintaining the driving.

The trailer rear axle can be divided into a number of types according to different classification methods, such as drum type and disc type, light weight type and heavy load type, ordinary type and maintenance-free type, American type and German type and so on. A few days ago, an owner consulted with DARO trailer axle, he wanted to replace the vehicle with a new axle, but he was not clear whether the original axle was American or German, and wanted to ask how to distinguish.

Today, DARO trailer axle will focus on sharing with you the difference between American trailer axle and German trailer axle for your reference.

Under normal circumstances, the design of German axles is more complex than that of American axles, which is also to meet the lightweight and long-term performance characteristics of German axles.

From the appearance point of view, the brake drum surface of the German axle is multi-reinforced. On the one hand, these stiffeners can enhance the strength of the brake drum and avoid cracking or deformation to a greater extent; On the other hand, in the process of high-speed vehicle driving, these reinforcing bars can improve the flow speed of air, improve the heat dissipation efficiency of the wheel end, and avoid overheating of the wheel end.

From the maintenance point of view, the accessories used in German axles are not common with American axles, and need to be purchased separately, even if the grease is generally used in German special products.

Of course, to say that the most significant and most reliable difference between German axles and American axles is on the axle head, that is, after the axle removes the wheel hub, brake drum, bearings and other wheel end parts, the two ends of the shaft beam are exposed.

The shape of the shaft head of the German type axle is more complex, showing an irregular cone shape in general, the part near the shaft beam is thicker, the diameter is finer to the two ends, and the production process and processing accuracy requirements are higher.

Such a design of the shaft head can reduce the weight of the shaft beam to a certain extent, ensure the lightweight characteristics of the finished product, and also enhance the stability of the shaft head with bearings, wheels, brake drums and other components, the operation clearance is closer, the resistance is smaller, the use of longer, and the maintenance cycle is extended.

So, when choosing the rear axle of the trailer, which is better, the American axle and the German axle?

Again, as long as the condition is used correctly, it is a better choice.

The main performance of the German axle is light weight and stability, which can save fuel and tires, reduce the comprehensive cost of the vehicle, and can achieve long-term, durable and faster heat dissipation efficiency, which is more suitable for use in the working conditions with high requirements for transportation timeliness and vehicle participation, such as dumping, port, cold chain, green pass, express transportation and other fields.

In contrast, the American axle, the most significant advantage is that the bearing is good, more resistant, in addition to simple maintenance, cost-effective is relatively higher, basically do not pick goods, can be widely used in all kinds of general cargo transportation, so it has become the current domestic owners most favored a trailer axle style, the highest market coverage.
