Heavier-duty superimposed trailer crossbeam
The utility model relates to vehicular field, relates in particular to a kind of superimposed trailer, specifically is meant a kind of heavier-duty superimposed trailer crossbeam.
Traditional big girder construction is only stressed its load-carrying capacity usually, and structure is generally I shape or half I-shaped structure.But in superimposed trailer when load-carrying is big; Particularly when vehicle ' is on turning or uneven road surface; Crossbeam can be received side force and the effect of turning round bending force; Thereby cause the crackle or the fracture of each thin spot of crossbeam, the service life of having reduced crossbeam, even may cause very serious safe consequence.
The utility model content
The technical matters that the utility model will solve is to the existing in prior technology weak point, provides a kind of and has that anti-side-bend is strong with distortion power, the heavier-duty superimposed trailer crossbeam in raising crossbeam service life.
The technical solution of the utility model is, following a kind of heavier-duty superimposed trailer crossbeam is provided, and comprises the crossbeam body, also is welded with deep floor on the described crossbeam body.
After adopting above scheme; The utility model has welded deep floor on the crossbeam body; Thereby crossbeam lateral force resistance and anti-twist power have been improved greatly; And then make be able to prolong the service life of crossbeam, and reduced the possibility that crossbeam cracks and ruptures and take place, help to improve the carrying capacity and the concentrated cargo capacity of superimposed trailer.
As preferably, described deep floor is " Γ " type.The deep floor of this preferred version is convenient to welding, and lateral force resistance and anti-twist power are stronger.
As preferably, described crossbeam body is " worker " font.This preferred version is that superimposed trailer crossbeam body construction is common version, has load-carrying capacity preferably.
As preferably, described crossbeam body is half " worker " font, and the promptly said crossbeam body only side on riser is provided with upper backup pad.This preferred version also is a common version in the big girder construction of superimposed trailer, and it is lower to have a cost, and bearing capacity is advantage preferably.

The specific embodiment
For ease of explanation,, the specific embodiment of utility model is elaborated below in conjunction with accompanying drawing:
As shown in fig. 1, a kind of heavier-duty superimposed trailer crossbeam comprises crossbeam body 1, also is welded with deep floor 2 on the described crossbeam body 1, and described deep floor 2 is " Γ " type, and in the present embodiment, described crossbeam body 1 is " worker " font.
As shown in Figure 2; A kind of heavier-duty superimposed trailer crossbeam comprises crossbeam body 1, also is welded with deep floor 2 on the described crossbeam body 1; Described deep floor 2 is " Γ " type; In the present embodiment, described crossbeam body 1 is half " worker " font, and the promptly said crossbeam body 1 only side on riser is provided with upper backup pad.
Should explain that at this " Γ " type that the utility model is mentioned because of the view direction relation, for symmetrical with " Γ " type, its essence is equally in the accompanying drawing in the specific implementation.
In the above-described embodiments; Preferred forms to the utility model is described, obviously, and under the inventive concept of the utility model; Still a lot of variations can be made, left side or the right side of crossbeam body etc. can be welded on like the position of described deep floor 2 welding as required.At this, should explain that any change of under the inventive concept of the utility model, being made all will fall in the protection domain of the utility model.
