Abstract
The utility model relates to a semitrailer girder, including last pterygoid lamina, web, lower pterygoid lamina, characterized by: the upper wing plate, the web plate and the lower wing plate are of an I-shaped integrated structure, steps are arranged at two ends of the upper portion of the upper wing plate, the joint of the upper wing plate and the web plate is in large-arc transition, the thickness of the lower portion of the web plate is increased, the web plate is in 45-degree angle transition with the upper portion of the web plate, the joint of the web plate and the lower wing plate is in large-arc transition, and the upper surface of the lower wing plate is formed by two 'U' -shaped surfaces which are symmetrical to each other. The advantages are that: the structure of the utility model is suitable for integral extrusion molding by aluminum alloy materials, the whole weight is light, the damage of high welding temperature to the strength of the plate is avoided, the welding deformation is reduced, and the energy consumption is effectively reduced; the aim of light weight of the semitrailer is fulfilled; according to the stress characteristic of the girder, the structure of each part is adjusted, the bearing capacity of the girder is effectively improved, and the problem of lap joint of the bottom plate and the girder is solved.
Description
Technical field
The utility model relates to a kind of semitrailer crossbeam, belongs to semi-mounted bicycle beam technical field.
Background technology
The semitrailer crossbeam material of traditional structure typically selects steel plate to make, upper flange, web, lower wing plate are welded into I-shape construction (Fig. 1), the semitrailer crossbeam building form of this structure is overall continuous welding fabrication, welding bead is many, processes relatively time consuming and energy resource consumption big, produces high temperature in welding process, destroy original intensity of sheet material, causing longeron (web) to deform in welding process, owing to being made by steel plate, weight is big.
Content of the invention
The purpose of this utility model be to provide a kind of use aluminium alloy global formation, lightweight, intensity is high, the bearing capacity that is effectively improved crossbeam is strong, and can solve the problem that the semitrailer crossbeam of base plate and the overlap joint of crossbeam.
The purpose of this utility model realizes with the following methods:
The utility model includes upper flange, web, lower wing plate, it is characterized in that: upper flange, web and lower wing plate are I-shaped integrative-structure, it is provided with step in upper flange both upper ends thereof, upper flange is orthodrome transition with the junction of web, the bottom thickness of web increases, top with web is 45° angle transition, and web is orthodrome transition with the junction of lower wing plate, and the upper surface of lower wing plate is with web for two symmetrical "U" shaped faces.
The utility model has the advantages that: the monolithic extruded shaping of the applicable aluminum alloy materials of structure of the present utility model, overall weight is light, it is to avoid the welding destruction to timber intensity for the high temperature, decreases welding deformation, effectively reduces energy resource consumption；When decreasing Welder, reduce production cost, it is achieved that the light-weighted target of semitrailer；According to the mechanical characteristic of crossbeam, have adjusted the structure at each position, effectively raise the bearing capacity of crossbeam, solve the overlap joint problem of base plate and crossbeam simultaneously.
Brief description
Fig. 1 is the structural representation of the semitrailer crossbeam of prior art；
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Referring to the drawings 2, the utility model includes upper flange the 1st, web the 2nd, lower wing plate 3, upper flange, web and lower wing plate, for using the I-shaped integrative-structure of aluminum alloy materials global formation, are provided with step 4 in upper flange both upper ends thereof, can ride over semitrailer base plate and weld herein；Upper flange is orthodrome transition with the junction of web, adds the intensity of crossbeam.The bottom thickness of web increases, and the top with web is 45° angle transition, and web is orthodrome transition with the junction of lower wing plate, adds the intensity of crossbeam.The upper surface 5 of lower wing plate is with web for two symmetrical "U" shaped faces, thickeies the local, two ends of lower wing plate, is effectively improved the intensity of crossbeam.
