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.

Semi-trailer axle refers to the axle installed on the semi-trailer bucket, which generally belongs to the support axle, neither with steering function nor driving function, and is specially used to bear the weight of the body.

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.

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

Many owners in the purchase of trailer axles, often asked about a parameter is the wheel base, just like choosing clothes to see the size, the wheel base also determines whether the trailer axle can match the vehicle.Generally speaking, under the same load-bearing tonnage, there are often trailer axles with different wheel bases, and how to measure the main vehicle to get an accurate wheel base value?Wheel base refers to the distance between the center line of the track left by the wheel on the vehicle support plane, which can be visually judged by the following figure:Therefore, if the two si

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.

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).

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.
