Airbagged trailer axles-manufacture,factory,supplier from China

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.

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.

With the continuous improvement of vehicle production technology, there are more and more large and small axle brands in the market. Can say which brand qualification old, cost-effective and high, DARO trailer axle is definitely among the best. Especially in many old driver's car, printed "RSCCZ" logo axle is not rare.The product categories are rich to meet the different needs of usersDARO Heavy Industry Group, formerly known as DARO Traffic Machinery Co., LTD., was founded in 2001 and has a history of 20 years.

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

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

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).

As a typical support axle, the trailer axle plays an important role in the fields of load bearing, braking, driving and even auxiliary shock absorption. In general, the trailer rear axle can be divided into two categories: disc type and drum type, and the subdivision can cover low flat trailer axles, three-line six-axles, eccentric trailer axles, special trailer axles, and so on. Today, we focus on low flatbed trailer axles.1.
