Abstract
The utility model belongs to the technical field of vehicles, in particular to an aluminum I beam used in vehicle crossbeam production or load frame production and with light weight, which comprises an upper wing, a lower wing and a web which is respectively and fixedly connected with the upper wing and the lower wing, and the upper wing of the I beam is a hollow upper wing. The I beam is light in weight and large in strength, thereby being capable of being widely used in manufacture of products like vehicle load bearing beams.
Description
Technical field
The utility model belongs to the vehicle technology field, relates in particular to a kind of I-shape beam that is used to produce vehicle crossbeam, carrying and stressed member.
Background technique
Economize on resources, the protection environment, very urgent; Automobile industry is duty-bound especially.Body lightening is the effective way that automobile industry economizes on resources, and also is the forward position and the direction of automotive engineering development.The light-weighted document of research automobile covers the sky and the earth, and grows with each passing day.Mention in " body lightening and steel aluminium integral structure Research progress of new techniques " (being stated from " automotive engineering journal ", in June, 2008, the 44th the 6th phase of volume) literary composition: " the every loss of weight 10% of automobile, oil consumption can reduce 6%-8% ".Point out in " lightweight of opinion automobile " (being stated from " Chinese process engineering ", 2009 9 phases) literary composition " the every loss of weight 10% of automobile, oil consumption can reduce 6%-8%, discharging descends 4% ".Suchlike argumentation has proved light-weighted significance of automobile and necessity once more.Since it is so to important, the task of putting so in face of us is exactly how to realize the automobile lightweight.
Automotive frame or load-carrying frame are the automobile important component parts, how to realize the lightweight of automotive frame or load-carrying frame, are to realize the light-weighted essential step of automobile.With regard to present disclosed document, the crossbeam of automobile or the load-carrying frame overwhelming majority adopt steel structure, adopt the less of aluminium matter structure; And no matter steel structure still is an aluminium matter structure; All be solid, aluminium matter structure is compared with steel structure, has reduced the weight of automobile; But, still do not reach the lightest.Therefore, it is little to develop a mass, and automotive frame that intensity is high or load-carrying frame are for being badly in need of.
The model utility content
The utility model technical problem to be solved provides a kind of little aluminium matter I-shape beam of quality that can be used for producing vehicle crossbeam or load-carrying frame.
Further, the utility model technical problem to be solved provides a kind of aluminium matter I-shape beam that quality is little, intensity is high that can be used for producing vehicle crossbeam or load-carrying frame.
In order to address the above problem, the technological scheme that the utility model provided is:
Aluminium matter I-shape beam, the upper limb of described I-shape beam are hollow upper limb.
Preferably, the web of described I-shape beam is hollow web.
Preferably, the bottom wing of described I-shape beam is hollow bottom wing.
Preferably, described hollow upper limb, perhaps hollow web, there is stiffening rib perhaps hollow bottom wing inside.
Preferably, between said stiffening rib and the hollow I-shape beam inwall for being fixedly connected.
Preferably, described stiffening rib is at least one.
Preferably, described stiffening rib cross section be shaped as circle, perhaps adjacent stiffening rib is formed is shaped as triangle, perhaps trapezoidal.
The beneficial effect of the utility model is: 1. quality is little.The density of aluminium is littler than steel, has huge light weight advantage.With regard to hollow aluminum matter I-shape beam, no matter be to compare with solid steel I-shape beam or compare with solid aluminum matter I-shape beam, all have the little advantage of absolute quality; 2. intensity is high.Before setting forth this beneficial effect; Earlier hollow aluminum matter I-shape beam is done a classification; With two block-shaped, material, the onesize hollow I-shape beam of rank street area is that example is classified: one type is that the outer wall of hollow I-shape beam is thicker; Hollow-core construction does not influence the intensity of I-shape beam, and one type is the outer thinner of hollow I-shape beam, influences the intensity of hollow I-shape beam.Last type itself just have high-intensity performance advantage, and back one type promptly has high-intensity advantage after adding stiffening rib, promptly because stiffening rib has support, reinforcing, effect such as stable, therefore guaranteed the intensity of hollow aluminum matter I-shape beam.This shows that hollow aluminum matter I-shape beam has high-intensity advantage; 3. energy-conserving and environment-protective.Because hollow aluminum matter I-shape beam has the little advantage of quality, therefore, also reduce with the quality of the vehicle of its production thereupon, also just reduce oil consumption certainly, reduce discharging, reach effect in energy saving and environmental protection.In automobile main forces, this whole structure is also inevitable more obvious.

Embodiment
Below in conjunction with accompanying drawing and embodiment to the technological scheme of the utility model do one briefly, clearly explanation.Obviously; Given embodiment is intended to explain content, the principle of present technique scheme as most preferred embodiment; But not whole mode of executions; Those skilled in the art can obviously make other embodiments according to the contents such as accompanying drawing of cited embodiment and present specification, and these embodiments belong to the equivalent of model utility, and belonging to originally is the protection domain of model utility.
As shown in Figure 1, aluminium matter I-shape beam, the upper limb of I-shape beam, bottom wing, web are hollow, between upper limb, bottom wing, the web or as shown in Figure 1 being interconnected, or the mutual isolation shown in Fig. 2, or mutual intersection as shown in Figure 3; Be fixedly connected between web and upper limb, the bottom wing.
Embodiment 2
As shown in Figure 4, aluminium matter I-shape beam, the upper limb of I-shape beam, bottom wing, web are hollow; And in upper limb, bottom wing, the web stiffening rib is arranged; Every stiffening rib is fixedly connected with upper limb, bottom wing, web inwall respectively, and described fixed connection is an extrusion moulding perhaps promptly, or welding; Stiffening rib or 1, or more than 1; The cross section of stiffening rib or triangle, or trapezoidal, or circular, or triangle, trapezoidal, circular combination in any.Need to prove, the function of stiffening rib be support, reinforce, stable, so sectional shape can be arbitrarily, the cross section that provides in the present embodiment be triangle, trapezoidal, circular stiffening rib be experiment and produce in best several kinds of effect.
