How to achieve lightweight trailer safely?

With the traffic management department to strengthen the control of overload transportation, vehicle lightweight gradually become an industry trend, more and more owners in the purchase of trailer and its parts, more inclined to choose those stable performance but their own weight lighter products, which also to a certain extent to promote the trailer, parts manufacturers in the material, process, structure and other aspects of continuous optimization and improvement.

In general, the trailer wants to achieve lightweight, the common ways are as follows:

1, reduce plate thickness, choose high steel standard, high strength, good toughness of steel.

2, reduce the weight of trailer axle, take light axle, disc brake and other measures.

3, choose lightweight girder, such as the use of special-shaped punching, reduce the height of the vertical plate and the width of the upper and lower wings.

4, choose a lighter weight suspension system, such as air suspension.

5. The suspension rear axle can be lifted when not in use.

6, reduce the weight of accessories, such as bumper, protective mesh, spare tire frame, toolbox, tarpaulin frame, etc.

7, twin for a single tire, such as some manufacturers of large single tire, weight loss is also very considerable.

Reasonable lightweight design or improvement can effectively reduce the weight of the trailer itself, increase the owner's choice range for the weight or type of goods, but also reduce fuel consumption, energy saving and environmental protection at the same time improve the transportation efficiency.

However, we should also see that although lightweight is a big trend in the industry, it must be based on safety. In particular, trailer vehicles, as the main force of cargo transportation, have higher requirements in load-bearing performance and transportation safety, so it is necessary to fully consider the reality in lightweight, and make lightweight improvement on the premise of ensuring safety performance. If the pure pursuit of "light weight" at the expense of safety, it is not worth the loss.

For example, the trailer axle weight reduction in the above lightweight approach. As we all know, the axle is the main load-bearing component of the trailer. It is connected with the body through the suspension to support the weight of the body and distribute the load to each tire to ensure the running of the trailer.

As a load-bearing component, the realization of lightweight design is not simply to change the material can be solved, especially in the premise of ensuring that its load-bearing performance is not reduced or even enhanced, to achieve its own weight reduction, it is not an easy thing.

Some little-known small manufacturers, in R & D capacity, production technology, manufacturing process and other aspects are not strong support, simply use extensive to achieve lightweight, such as reducing the amount of steel or the selection of light steel toughness is not up to standard, so that the production of trailer axle although from the appearance can not see what obvious difference, even in weight advantage, But once put into use, with the passage of time, under the high bearing force and changing road conditions, it is easy to appear metal fatigue, bending, cracking or even torsion, which seriously threatens the safety of operation.

Therefore, when the owners choose lightweight products, they should not blindly believe the words on the advertisement, but also shop around and do more research. Only the products that can withstand the test of the market and users can guarantee the safety of travel. For example, the lightweight axle produced by DARO Group selects 20Mn2 high-strength alloy seamless steel pipe to ensure strength, toughness and lightweight from the raw material. At the same time, it is equipped with one-piece heat treatment molding technology, integral axle housing casting, powder spraying + electrophoresis process, three-hole boring finishing machining of brake bottom plate after welding, shaft head finishing processing, medium frequency induction processing and other more than ten processes. Under the premise of improving the bearing capacity of the axle and extending the service life of the axle, it takes into account the lightweight and reduces the weight of the axle by 15%-20% compared with the traditional axle. The finished products have been tested before leaving the factory to ensure quality standards, stability and reliability.
