According to the regulations of GB1589, the main models of five-axle articulated trailers can be divided into three types: 4*2+3, 6*2+2 and 6*4+2.

For car owners who run transportation, 4*2 light trucks should be no strangers. As recognized in the industry as the "ten-ton king" and "overloaded god car", 4*2 light trucks can be said to be all-in-one in terms of cargo selection.

Hub bearing is one of the key components on the trailer, the main role is to carry weight, to provide accurate guidance for the rotation of the wheel end, not only to bear the axial load, but also bear the radial load.Hub bearings require regular maintenance, and the maintenance cycle of different brands also has certain differences. Under normal circumstances, the maintenance cycle of non-maintenance-free hub bearings is 1W km-5W km, and the maintenance cycle of maintenance-free bearings is longer, generally in 10W km-50W km.

Steel wire tire and vacuum tire adapted modelsFirst of all, there are steel tires and vacuum tires, which are subdivided into a variety of trailer axle models, and different models are adapted to different models.Among them, the most common on the market are 11.00R20 steel wire tires and 12.00R22.5 vacuum tires, which are widely used in flower baskets, standard cars, roll-over dump and various types of hazardous chemical vehicles, of which 12.00R22.5 vacuum tires are equipped with good long-distance road conditions, and the pattern is mostly 3 or 4 lines.Road conditions are poor, short distanc

8X4 trucks have always been the main force of transportation in the freight market. They have good stability, strong loading capacity, and can pull a lot of goods. They are "all in size" for goods, especially in the transportation of short- and medium-distance materials such as green transportation, less-than-truckload, and cold-chain transportation. It plays an extremely important role.The so-called "8X4" means that the total number of wheels of the vehicle is 8 groups, of which there are 4 groups of driving wheels.

With the new version of GB1589 standard has been implemented in China, some owners in order to earn more money will not break the law, metropolitan choose lightweight truck vehicles. In terms of tractors, even if no matter how to lose weight, trailer suspension the lightest 6×4 semi-tractor will not break the 7.5 ton mark.So some owners decided to replace the trailer to achieve legal overloading. But recently, a new domestic trailer manufacturer that produces "stronger semi-trailers" began to enter people's field of vision.

    The Ministry of Transport, in conjunction with the Ministry of Finance, is implementing the national comprehensive freight hub replenishment and strengthening measures.

Axle is one of the key components on the trailer, is a set of core parts assembly, its performance is directly related to the load bearing, braking and driving of the vehicle. Therefore, the maintenance and maintenance of the axle is crucial to the safety of the operation of the vehicle.In general, trailer axle maintenance mainly includes lubrication grease filling/replacement, fastener detection, brake gap adjustment, brake drum/brake pad inspection, etc.

Bearing is an important part of the trailer axle. As a high-precision, high-strength and high-speed part, it plays an important role in force transmission, decompression and buffering on the trailer chassis.Specifically, there are three main functions of bearings:1, bearing weight, for the hub of the steering to provide accurate guidance, not only to bear axial load, but also bearing radial load.2, maintain the flexibility of vehicle steering, so that the vehicle steering, the shock absorber can follow the wheel rotation;3. Cushion the vibration from the road surface.

The axle is one of the very important parts on the semi-trailer, which is directly related to the bearing, driving and braking of the vehicle, and the engine and transmission are called the three core assembly of the trailer, which plays a decisive role in the stability and safety of the vehicle.Maintenance-free trailer axle refers to the maintenance and maintenance cycle is relatively long axle, general oil lubrication instead of grease lubrication, in the hub unit with gear oil, so that the hub and oil seal form gear oil storage space, let the bearing soaked in gear oil, to ensure its full l
