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

Semitrailers are one of the main categories of trailers. They refer to trailers with axles positioned behind the center of gravity of the vehicle and equipped with coupling devices that transfer horizontal and vertical forces to the tractor. The semi trailer itself has no driving force, it needs to rely on the traction of the main car to achieve driving.Semi-trailer transport has high comprehensive economic benefits, which can be improved by 30-50% compared with ordinary monomer type cars.

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.

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 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.

The axle of a semi-trailer is an important load-bearing component, and its production process directly affects the performance and service life of the axle. The following is the production process of a general semi-trailer axle:1. * * Design phase * *:-Requirement analysis: Determine the load-bearing capacity, dimensions, weight, and other parameters of the axle based on the usage environment and requirements of the semi-trailer.-Design drawings: Use CAD software for 3D design and draw detailed drawings of the vehicle axle.2.

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.

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.

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 axle is one of the core components on the rear axle of a semi-trailer, and the strength of the axle is directly related to the load-bearing capacity of the trailer axle. For axles, the performance of the axle head is critical.The shaft head is the key part where the axle connects the wheel hub, brake drum, bearing and other wheel end components. Whether the performance of the subsequent wheel hub assembly is stable depends largely on the strength, toughness and precision of the shaft head. For example, if the end of the wheel is a high-rise building, then the axle head is the foundation.
