Problems solved by technology

The body structure of this kind of semi-trailer is relatively simple, and lacks a lateral support structure. When the body is subjected to lateral force, it is easy to cause deformation of the body, damage the body, and lead to safety accidents.

Abstract

The invention discloses a lightweight flat semi-trailer body, relating to the technical field of manufacturing a flatbed semi-trailer, comprising a bearing shell, a bottom plate and a support beam. The housing is bonded to the lower surface of the bottom plate to form a box structure with the bottom plate, a support beam is arranged in the box-shaped structure and is connected with the shell and the bottom plate, a support beam is arranged in the center of the box structure along the longitudinal direction of the vehicle body, reinforcing structures abutting on both side walls of the housing is disposed on both sides of the support beam in the housing, the reinforcing structures comprise a plurality of support frames arranged along the length direction of the shell, and the support framesare abutted against the two sides of the support beam and the inner wall of the shell. The invention solves the problem of low transverse structural strength of the semi-trailer body, has stronger transverse structural strength, and greatly improves load bearing capacity and robustness.

Description

technical field [0001] The invention relates to the technical field of flatbed semi-trailer manufacturing, in particular to a lightweight flatbed semi-trailer body. Background technique [0002] Existing flatbed semi-trailers are generally made of steel and are composed of base plates, vehicle frames, suspensions and wheel assemblies. Among them, the frame is a frame structure composed of two large I-shaped steel longitudinal beams and several cross beams that are larger than the total length of the bottom plate, providing the load-bearing capacity and rigidity required by the whole vehicle. Its disadvantage is that the weight of the vehicle frame itself is very large, and the consumption of steel materials will account for 25% of the weight of the vehicle. [0003] Fiber-reinforced composite material is a new type of material that has developed rapidly in recent years. It is usually composed of matrix resin and fiber reinforcement, and there are many methods of preparation...
