Aluminum alloy semitrailer longitudinal beam assembly

Abstract

The invention discloses an aluminum alloy semitrailer longitudinal beam assembly, and is applied to the technical field of semitrailers. The aluminum alloy semitrailer longitudinal beam comprises a longitudinal beam, wherein the longitudinal beam is made of aluminum alloy materials, and is divided into an ab segment, a bc segment and a cd segment in the length direction of the longitudinal beam; the ab segment, the bc segment and the cd segment adopt an integrated molding structure through a molding technology of an aluminum extrusion technology; the ab segment comprises an upper wing plate and a web, and the section of the ab segment is T-shaped; the bc segment comprises an upper wing plate, a web and a lower wing plate, and the section of the bc segment is H-shaped; the cd segment comprises an upper wing plate, a web and a lower wing plate, and the section of the cd segment is H-shaped; and gooseneck reinforcing plates are respectively arranged on one sides of the lower wing plates,and are connected with the web of the ab segment and the lower plate of the bc segment. Most current semitrailers are formed by the welding of steel structural components, and have the problems of being high in oil consumption, large in total semitrailer weight, poor in corrosion resistance, low in ratio of remaining value, and the like. Through the adoption of the aluminum alloy semitrailer longitudinal beam disclosed by the invention, the weight reducing effect can be improved under the condition of meeting the load required by laws, and the corrosion resistance, the recovery value, the ratio of remaining value and the economic benefit can be enhanced, so that the aluminum alloy semitrailer longitudinal beam has an extensive application prospect.

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...
