Embodiment 1

[0026] see figure 1 , a full-load commercial vehicle platform, the full-load commercial vehicle platform includes a car body skeleton, the car body skeleton includes a plurality of transverse facets and a plurality of longitudinal facets, and the intersection of the transverse facets and the longitudinal facets generates The nodes of are connected with the corresponding nodes of the adjacent facets to form the car body skeleton of the multi-dimensional triangular space frame structure. The skeleton structure of the car body is mainly composed of transverse facets and longitudinal facets. When the longitudinal facets containing several triangles and polygons are combined with the transverse facets, multiple intersection nodes will be formed. When the car body is subjected to loads, all end nodes participate in the transmission of the load, thereby forming a multi-dimensional force flow field space, making the car body a multi-dimensional closed force loop system. The load is ...

Embodiment 2

[0028] see figure 1 , 2 , 3. As an improvement of the present invention, the transverse facet includes a triangle or polygon formed by a transverse side beam 1 and a transverse brace 5 or a combination of a triangle and a polygon; the longitudinal facet includes a longitudinal side beam 2 and a longitudinal The triangles or polygons formed by the diagonal braces 6 or the combination of triangles and polygons. according to image 3 In the structure shown, several longitudinal facets of the car body are welded with longitudinal side beams 2, longitudinal braces 6 and frame rods, and then multiple longitudinal assembly and welding are performed after being positioned and clamped by tooling fixtures; and transverse side beams 1 It is welded with the corresponding nodes of the adjacent longitudinal facets to form a unified frame structure; the grid structure with a large span is welded diagonally with horizontal braces 5 to form a figure 2 The horizontal facet shown contains s...

Embodiment 3

[0030] As an improvement of the present invention, the number of the triangles and polygons is at least two. The polygons may be other polygons such as quadrilaterals, pentagons, and hexagons, and may be freely combined and matched according to actual needs. Its structure and advantage are identical with embodiment 1.

Abstract

The invention relates to a full-load commercial vehicle platform which is characterized by comprising a vehicle body skeleton, wherein the vehicle body skeleton comprises a plurality of transverse dimensions and a plurality of longitudinal dimensions. The panel point generated by the intersection of a transverse dimension and a longitudinal dimension is connected with a corresponding panel point of an adjacent dimension, so that the vehicle body skeleton in a multi-dimensional triangular space framework structure is formed. The plurality of transverse dimensions comprise triangles, polygons or combinations of triangles and polygons, wherein the triangles, the polygons or combinations of triangles and polygons are composed by longitudinal boundary beam and longitudinal inclined struts. By adopting the technical scheme, a vehicle body is lighter in self-weight, stronger in bearing capacity and better in structural stability. Due to the fact that the loading of the vehicle body affects on the vehicle platform all, cargo hold door with any size can be formed in any position in the tops side body and requirement of cargo loading, unloading is satisfied and efficiency and level of cargo handling are improved greatly.

Description

technical field [0001] The invention relates to a commercial vehicle platform, in particular to a fully loaded commercial vehicle platform and its application. Background technique [0002] In recent years, with the acceleration of my country's urbanization process, the rapid construction of high-grade road network has promoted the rapid development of my country's logistics industry, which has brought huge transportation capacity, high actual load rate, and low cost of trailers and semi-trailers. However, most of the current semi-trailers are trapezoidal body frames composed of I-beams and channel steels, and a sealed box is added to the frame to form a semi-trailer or full trailer. At present, the common semi-trailer body is mainly a grid-like plane structure composed of two longitudinal beams and several cross beams. Although the manufacturing process is simple and the technology is relatively mature, because it is a non-load-bearing structure, its dead weight is too larg...
