What is the role of the trailer axle? How to choose the trailer axle?

The axle is one of the core components on the trailer, and its quality and performance are directly related to the driving safety of the trailer, such as load bearing, braking, maintenance and so on. A high-quality trailer axle has high processing accuracy, good load-bearing performance, sensitive and efficient braking, long maintenance cycle, and good coordination between various parts, which can protect and reduce tire wear, not only ensure vehicle safety, but also help owners reduce comprehensive vehicle costs.

The basic function of the trailer axle is to transmit the force and torque in all directions between the frame and the wheel:

(1) The engine torque from the universal transmission device is transmitted to the drive wheel through the main reduction tire, differential, half shaft, etc., to achieve the reduction of speed and increase the torque;

(2) Change the direction of torque transmission through the bevel gear of the main reducer;

(3) The differential function of both sides of the wheels is realized through the differential to ensure that the inner and outer wheels turn at different speeds;

(4) Reduce the speed and increase the torque through the transmission of the main reducer gear;

(5) Through the axle housing and wheels, to achieve load and force transmission.

But like other consumer goods on the market, trailer axles also exist counterfeit products. These fake axle braking effect is poor, poor running performance, shaft beam, bearing, wheel hub easy to damage, light lead to tire wear and other phenomena, although it does not affect the driving, but increase a lot of car costs, heavy is easy to lead to safety accidents, such as brake failure, axle fracture, bearing damage, tire separation, etc., any kind of occur in the process of high-speed driving, the consequences are unimaginable, Transportation safety is not guaranteed.

The reason why the quality of these shoddy axle is not up to standard is largely related to its production technology. For example, the strength of the selected raw materials is not enough or the parameters are false, the process is backward in the production process and cannot reach the industry standard, and the straightening and heat treatment of the axle are unqualified, which can easily lead to the deformation of the axle after the factory, which will directly lead to the failure of the trailer in use.

The reason why some owners buy fake and shoddy products is largely due to cost issues. Now on the market of big brands of axle, the price is relatively expensive, such as the current new type of disc axle, the unit price can reach nine thousand or even more than thousand yuan, if a car needs three axle, the cost is about 30,000.

However, the owner should not let the initial price confused, although the inferior axle sold cheap, the subsequent series of use of the cost is expensive, the cost is not only not reduced, but much higher. Moreover, the qualified trailer axles on the market are not all priced very high, there are still some quality reliable and affordable brands, such as Darong Axle, as the Liangshan commercial vehicle base of the first batch production of integrated axles enterprise, has now been twenty years, strength and technology is trustworthy, the above series of production steps are the true picture of Darong factory. Many trailer enterprises, logistics companies have chosen Darong as a fixed axle cooperation, cost-effective, products can be used, save money and worry, won the market users widely praised.
