Aluminum alloy semitrailer longitudinal beam assembly

Abstract

The invention discloses an aluminum alloy semi-trailer longitudinal beam assembly, which is applied in the technical field of semi-trailers, and comprises a longitudinal beam, which is made of an aluminum alloy material and is divided into an ab section, a bc section and a bc section along the length direction of the longitudinal beam. cd section, the ab section, bc section and cd section are integrally formed, and the molding process is an aluminum extrusion process. Among them, the ab section includes the upper wing plate and the web, and its cross section is T-shaped; the bc section and the cd section include the upper wing plate, the web plate and the lower wing plate, and its cross section is I-shaped, and one side of the lower wing plate is provided with The gooseneck reinforcement plate is connected with the web plate of section ab and the lower wing plate of section bc. At present, semi-trailers are mostly welded by steel structural parts, which have problems such as high fuel consumption, heavy vehicle weight, poor corrosion resistance, and low residual value rate. The present invention can lift and reduce weight while meeting the requirements of regulations Effect, and improve corrosion resistance, recovery value, residual value rate, economic benefits, has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of semi-trailers, and in particular relates to an aluminum alloy semi-trailer longitudinal beam assembly. Background technique [0002] At present, the lightweight of automobiles has become the consensus of the automobile industry. At present, most semi-trailers are mostly welded by steel structural parts, which have problems such as large welding volume, high fuel consumption, and heavy vehicle weight. In the case of meeting the use requirements, the weight of the semi-trailer should be fully reduced, in response to the call for energy conservation and emission reduction, to save fuel costs for users and improve operating profits, so the proportion of aluminum alloy materials used in the vehicle structure is gradually increasing. [0003] The longitudinal beam is the main load-bearing part of the semi-trailer, and its strength affects the performance of the entire vehicle. In the case of meeting the requir...

AI Technical Summary

Problems solved by technology

In the case of meeting the requirements of the regulations, the weight reduction effect of the steel longitudinal beam assembly in the prior art is not obvious, and the corrosion resistance of the steel longitudinal beam assembly in the prior art is poor, the recycling value is low, and the residual The value rate is low, the comprehensive economic benefit is poor, and it has limited application prospects
