How to realize the lightweight of semi-trailer?
The advantages of lightweight semi-trailers are also the future development trend, but there are advantages and disadvantages, and there are gains and losses. Many truck drivers are blindly pursuing lightweight and neglecting the product itself. After turning the semi-trailer Xiaobian tells you how to
First, reduce the actual load interval
At present, the weight reduction of the trailer is largely to reduce the weight of the trailer by reducing the specifications of the trailer beam, beam, etc., and to reduce the specifications of the trailer material, and the overall load bearing capacity of the trailer will be reduced.
Second, the use of better materials, but more strict use of working conditions
1. By using higher-grade steel, replacing the original lower-weight steel weight reduction is one of the main means of lightweighting of trailers. It is common to use T700 steel, to achieve the same strength, such as the use of T700 high-strength steel, the same strength, manganese steel needs 10mm thick, T700 may only be 6mm thick. The weight naturally decreases.
2, higher strength steel, can reduce the amount of steel used, reduce the weight of the trailer, but different steel characteristics, will bring other problems. High-strength steel is not bent, unlike manganese steel, which has good toughness and no bending of the girders. The characteristics of high-strength steel girders determine that it can only be used for standard transportation of good road conditions, and manganese steel girders are used for mountain transportation.
3, the use of lighter aluminum alloy to reduce weight, lighter weight is more obvious. But price and maintenance are still a problem.
Third, optimize the design of the trailer, but the reliability needs to be further improved
1. Another method of weight reduction for trailers is to optimize the design of the trailer, such as forming a beam. Although the new technology of forming a beam can be said to be very effective for the lightweight of the trailer, sometimes the new technology also means risk.
