The trailer rear axle is a typical driven bridge, also known as the support bridge, does not have driving and steering functions, the structure is simpler than the steering bridge or the drive axle, and is connected to the frame through the suspension system, which plays the role of load-bearing, braking, shock absorption, and maintaining the driving.The trailer rear axle can be divided into a number of types according to different classification methods, such as drum type and disc type, light weight type and heavy load type, ordinary type and maintenance-free type, American type and German ty

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).

History of disc brake and drum brakeSince the German Karbenz invented the use of single-stroke internal combustion engine cars, the car speed finally barely reached 19 kilometers per hour, and in the future time to break through, at the same time the role of the braking system began to gradually reveal.At the beginning, the British invented the brake mode of hair stained asphalt with the brake drum, but with the increase of speed, this original brake method has a general effect, and it is easy to fail.

I do not know when to start, there has been a kind of goods called "return goods" in the freight industry. The so-called "return goods", the meaning is also very well understood, that is, the owner of the car in the return of the goods. In simple terms, if you pull back the goods, you can not empty the car when you run back, so you can save money on fuel and tolls.Logically speaking, the appearance of trailer axles return cargo can enhance the operation value of the return vehicle, which is helpful to both individuals and the industry.

Trailer axle is one of the key components of vehicle chassis, which is directly related to the efficiency of vehicle operation. From the perspective of classification, axles can be divided into four categories: drive axles, steering axles, steering drive axles and support axles.

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.

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 key components of the vehicle, which can perform the functions of bearing, braking, driving, steering and maintaining driving. According to the different driving methods, the axles can be divided into steering axles, driving axles, steering driving axles and purely driven supporting axles.The axle can be integral or disconnected, but their appearance and structure are not exactly the same.

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 one of the key components on the vehicle chassis, which is related to the performance of the vehicle body load-bearing, auxiliary braking and shock absorption. There are many types of trailer axles, such as drive axles, steering axles, drive steering axles, and support axles. From the structural form, they can be divided into two types: integral trailer axles and disconnected trailer axles.The integral trailer axle is easier to understand. Like the trucks we usually see, most of them use the integral trailer axle.
