Problems solved by technology

During the actual loading process, this kind of longitudinal beam often has obvious concave due to the poor rigidity of the aluminum alloy material. At the same time, due to the limitation of the tonnage of the extrusion machine, the "section size" of the extruded profile is also limited, especially the height of the longitudinal beam. size
This kind of longitudinal beam obviously has many limitations for semi-trailer products with high strength requirements.

Embodiment Construction

[0095] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0096] When describing the orientation in the present invention, the normal driving direction of the semi-trailer is taken as the front, the other side opposite to the front is taken as the rear, the direction close to the center of the cross-section of the semi-trailer is taken as the inside, and the direction away from the center of the cross-section of the semi-trailer is taken as the outside. .

[0097] see Figure 1-Figure 7 , is a structural schematic diagram of the first embodiment of the longitudinal beam of a semi-trailer, as figure 1 As shown, the semi-trailer includes a vehicle frame 100, a traction assembly 200, an outrigger assembly 300, a rear b...

Abstract

The invention provides a longitudinal beam of a semi-trailer and a semi-trailer. The longitudinal beam at least includes two components, an upper wing plate and a lower wing plate. The longitudinal beam assembles and fixes the components into shape through fasteners. The present invention provides a longitudinal beam of a semi-trailer. By setting the longitudinal beam and fixing the parts through fasteners, a large amount of welding workload is reduced, and quality defects caused by welding are avoided. The use of fasteners to connect and fix completely avoids the problems of quality defects and high labor costs caused by welding, improves the product quality of the semi-trailer longitudinal beams, reduces the post-processing of quality defects, and reduces labor costs.

Description

technical field [0001] The invention belongs to the technical field of semi-trailers, and in particular relates to a longitudinal beam of a semi-trailer and a semi-trailer with the longitudinal beam. Background technique [0002] At present, the longitudinal beam of the semi-trailer mostly adopts Q345 or Q235 steel structure, which is shaped like an "I", and is composed of three flat plate parts welded by the upper wing plate, the web plate and the lower wing plate. There are many problems caused by this welding process: for example, the large amount of welding leads to serious deformation of the girder welding, poor dimensional control and other defects; the inspection during and after welding is time-consuming and laborious; the consumption of more man-hours leads to a corresponding increase in manufacturing costs and labor costs ; Later maintenance costs are relatively high. At the same time, most of the longitudinal beams are steel structures, which not only greatly inc...
