7500 lb trailer axles-manufacture,factory,supplier from China

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

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 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.

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

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.

Semi-trailer is a common transport model used in China, which does not have a driving force and needs to be driven by tractor. Trailer axles installed on semi-trailers are generally support Bridges, do not have steering or drive functions, and are designed for load bearing.When it comes to trailer axles, we can easily think of 13t, 16t, 20t axles or 10t light axles, of which 13t axles are the most common.

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 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.

Lightweight is the mainstream trend in the current automotive industry, and freight vehicles are no exception. Driven by this trend, the application frequency of airbag axles is becoming higher and higher, from tractor to semi-trailer, it can be seen.Compared with the steel bridge, the airbag trailer axle is light in both material and weight, leading many owners to question whether it can afford the weight of the goods.In fact, such doubts are unnecessary.
