What is the fatigue test for? Why do trailer axles need fatigue tests? Today, let's walk into the production workshop of DARO Group to take a close look at the work of the fatigue test bench.When choosing an axle, many owners want to understand the basic situation of the product from all aspects, such as strength, toughness, load-bearing force, service life and so on. However, these data are often just a number or adjectival appearance, many owners feel more boring, after reading, listening to no impression.

The trailer axle is no stranger to the owners. As an important part of the chassis, it plays an irreplaceable role in vehicle performance. To produce an axle, in addition to raw materials, it also needs bearings, hubs, brakes, friction plates, camshafts, bolts, washers, adjusting arms and other large and small parts of nearly 100.These parts and the axle is the whole and part of the relationship, but also determines the quality and performance of the axle finished key factors. Today, we're going to talk about the treasure trove suppliers behind DARO's trailer axles.1.

According to different division methods, automobile axles can be divided into many types, such as integral axles and disconnected axles according to structure, and steering axles, drive axles, steering drive axles and support axles according to functions. Among them, the drive axle can be subdivided into single-stage reduction axle (half axle axle) and double-stage reduction axle (wheel side axle, wheel reduction axle).

Semi-trailer axle refers to the axle installed on the semi-trailer bucket, which generally belongs to the support axle, neither with steering function nor driving function, and is specially used to bear the weight of the body.

As one of the more widely used models in the domestic logistics industry, semi-trailer plays an extremely important role in road transportation. According to the number of axles, the load limit of the semi-trailer is also different.How to limit the number of axles and load of semi-trailer?According to the regulations of GB1589 "Automobile, Trailer and automobile train exterior size, axle load and mass limit", the maximum allowable total mass limit of one-axle semi-trailer is 18t, the limit of two-axle semi-trailer is 35t, and the limit of three-axle semi-trailer is 40t.

For a long time, brake safety has been a very concerned issue for car owners. For freight vehicles, the load is usually relatively large, the inertial effect of braking is also relatively strong, especially in the need for continuous braking on the road, the brake often appears hot because of frequent braking. The water-cooled trailer axle is a product for the overheating of the brake.Water-cooled trailer axles first appeared in the public eye about 17 years ago, which was a relatively new invention at that time.

Maintenance-free trailer axles appear more frequently on some high-end freight models, and the purpose of its application is to extend the maintenance cycle of the wheel end, reduce the frequency of maintenance, improve the efficiency of vehicle operation, and reduce the downtime caused by maintenance.The so-called maintenance-free axle is to replace grease lubrication with oil lubrication, fill the gear oil in the hub unit, the hub and the oil seal form a storage space for the gear oil, and soak the bearing in the gear oil to ensure its full lubrication capacity to achieve longer maintenance

Axle is one of the important parts on the semi-trailer, to fully protect the attendance, safety and economic efficiency of the semi-trailer in the long-distance journey, it is vital to choose a high-quality axle.Nowadays, lightweight has gradually become a trend in the semi-trailer industry, and more and more owners prefer to choose those products with stable performance and lighter weight when they purchase semi-trailers or accessories.

The trailer axle is a typical driven axle, its main function is load bearing and auxiliary braking. Compared with the drive steering shaft, the structure of the trailer axle is relatively simple, mainly composed of axle body assembly, brake assembly, wheel end assembly, camshaft assembly and other components.From a structural point of view, common trailer axles are mainly divided into the following types:1. Drum trailer axleThe drum trailer axle is the most widely used trailer axle in the domestic market.

The axle is one of the key parts of the semi-trailer, which is responsible for the load bearing, braking and maintenance of the vehicle. Many owners in the purchase of axles will face a problem: why look similar trailer axles, the price is so much different? Today, let's have a good talk about this topic.First, the choice of raw materials.In fact, no matter what brand of axle, its raw material is basically steel.
