How to distinguish German Axle from American Axle

Generally speaking, the design of German axles is more complex than that of American axles. This is also to meet the lightweight and long-lasting performance characteristics of German axles.

From the appearance, the surface of the brake drum of the German axle is often reinforced with ribs. On the one hand, these reinforcing ribs can enhance the strength of the brake drum and prevent the brake drum from cracking or deforming to a greater extent; on the other hand, during high-speed driving of the vehicle, these reinforcing ribs can increase the flow speed of the air and improve the wheel end's durability. Heat dissipation efficiency to avoid wheel end overheating and failure.

From a maintenance point of view, the accessories used for German-style axles are not common with American-style axles and need to be purchased separately. Even the grease generally requires German-specific products.

Of course, the most obvious and reliable difference between German axles and American axles is the axle head, which is what is revealed after the axle removes wheel end parts such as hubs, brake drums, and bearings. The positions of both ends of the axle beam.

The shape of the axle head of the German axle is relatively complex, generally showing an irregular cone shape. The area close to the axle beam is thicker, and the diameter becomes thinner towards both ends. The requirements for production technology and processing accuracy are also higher.

Such a shaft head design can reduce the weight of the axle beam to a certain extent and ensure the lightweight characteristics of the finished product. In addition, it can also enhance the stability of the cooperation between the shaft head and bearings, wheel hubs, brake drums and other components, resulting in closer operating clearance and smaller resistance. , it lasts longer and the maintenance cycle is also extended.

So, when choosing a trailer rear axle, which one is better, American axle or German axle?

The main performance of German-style axles is light weight and stability. It can not only save fuel and tires, reduce comprehensive vehicle costs, but also achieve long-lasting, durable and faster heat dissipation performance. It is more suitable for transportation timeliness and vehicle attendance rate. Working conditions with higher requirements, such as drop and pull, ports, cold chain, green transport, express transportation and other fields.

On the other hand, the most significant advantages of American-style axles are that they have good load-bearing capacity and are more resistant to damage. In addition, they are simple to maintain and have a relatively higher cost performance. They basically do not have to pick goods and can be widely used in all types of general cargo transportation. Therefore, they are also It has become the most popular axle style among domestic car owners, with the highest market coverage.
