Problems solved by technology

[0004] The object of the present invention is to provide an improved assembled semi-trailer frame, which can overcome the inability to disassemble the package between the parts of the welded semi-trailer in the prior art, thus seriously affecting the transport volume of the semi-trailer and increasing the volume of the semi-trailer. The transportation cost of the trailer; the welded structure is prone to welding defects during welding, which leads to cracking of the weld seam in some stressed and complicated parts of the semi-trailer. Once the component is damaged, it cannot be quickly replaced and repaired.

Abstract

The invention relates to an assembled semi-trailer frame. The assembled semi-trailer frame is characterized in that the frame is composed of longitudinal beams, middle cross beams and penetrating cross beams, wherein the middle cross beams and the penetrating cross beams are connected with the longitudinal beams; two boundary beams are arranged on the two sides of a bottom plate respectively, and the two ends of the bottom plate are each provided with a front-back cross beam; the boundary beams and the front-back cross beams are in assembled connection through connecting pieces, and the front-back cross beams and the longitudinal beams are in assembled connection through cross beam connecting plates; the middle cross beams are of a Z-shaped structure; the longitudinal beams are provided with webs and lower wing plates; and Z-shaped supports are arranged on the webs of the longitudinal beams, and the middle cross beams and the two longitudinal beams are connected through the Z-shaped supports. In the using process, the assembled structure of all parts has enough connecting strength and anti-bending and anti-twisting strength, the phenomenon that a connecting bolt bears too large shear force in the acceleration or emergency brake process of a semi-trailer is avoided, and the frame can also be prevented from being twisted or deformed when the semi-trailer travels on a complex road surface. The assembled structure of all the parts has manufacturability and maneuverability, so that part machining and overall assembling are facilitated.

Description

technical field [0001] The invention relates to the technical field of a semi-trailer, in particular to a vehicle frame for an assembled semi-trailer. Background technique [0002] With the rapid development of the economy, the demand for semi-trailers is increasing. At present, semi-trailers are generally welded by parts. This welding structure is not conducive to the modularization and mass production of semi-trailers by manufacturers, and it is also impossible to form batch processing of parts. , A new production mode of off-site assembly. [0003] Moreover, when the semi-trailer needs long-distance transportation (especially container transportation), the parts of the semi-trailer with welded structure cannot be disassembled and packaged, which seriously affects the volume of the semi-trailer and increases the transportation cost of the semi-trailer; at the same time, welding The structure is prone to welding defects during welding, which leads to cracking of the weld s...
