torsion trailer axles-manufacture,factory,supplier from China

Trailer suspension is used to connect the frame and axle components, the main role is to transmit the force and force torsion between the wheel and the frame, buffer the impact of the road to the body, and maintain the smooth running of the vehicle.

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

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.

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.

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.

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
