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.

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

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 load-bearing components of the vehicle. The upper part is connected to the vehicle body through the suspension, and the two ends are used to install the wheels, which can not only support the weight of the vehicle body, but also maintain the normal driving of the vehicle on the road.The axle can be integral, which looks like a big barbell, or it can be disconnected, like two umbrellas inserted on both sides of the vehicle body.

Common trailer axles can be divided into four types: drive axle, steering axle, steering drive axle and support axle.1.

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.

Under normal circumstances, the trailer wants to achieve lightweight, there are the following common ways:1, the use of lighter weight materials, such as aluminum alloy instead of steel, common like aluminum alloy body, aluminum alloy transmission, aluminum alloy drive shaft, aluminum alloy fuel tank, aluminum alloy rim, etc.;2, the vehicle appearance and interior parts use new materials, such as long fiber reinforced materials, low density PP materials, low VOC green materials, spray free materials, halogen-free flame retardant materials, etc.;3, reduce the thickness of the plate, the use of

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.

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.
