Compared with the prior art, the automobile main frame is advantageous in that the strength and rigidity of the main frame can be improved while the lightweighting of the main frame is guaranteed, the motion shock loading can be effectively absorbed, and the safety can be improved.
Description
[technical field]
The utility model relates to a kind of automobile chassis frame, relates in particular to a kind of automobile primary vehicle frame.
[background technology]
Main car frame is the key structure of automobile, it also will bear the elliptical gear load that vehicle produces in traveling process except will carrying the static load of car load, and at present main car frame longeron on the market is generally welded by multi-sheets or bending forms, this structure can cause stress concentration phenomenon, has larger potential safety hazard.Moreover vehicle lightweight becomes the development tendency of current automobile, and main car frame lightweight is the effective way of the trend of catering to, so how in not only alleviating main car frame weight but also promote the Rigidity and strength of main car frame, become a technical matters of needing solution badly.
Therefore, be necessary to provide a kind of new automobile primary vehicle frame to overcome above-mentioned technical matters in fact.
[utility model content]
The technical matters that the utility model need solve is a kind of lightweight to be provided, to guarantee main car frame strength and stiffness and the tool automobile primary vehicle frame of distribution of stress better.
A kind of automobile primary vehicle frame of the utility model, comprise two longerons that are oppositely arranged and be at least onely fixed on the crossbeam between longeron described in two, described longeron tool sidewall and vertically extended laterally the upper face that forms, vertically extended to the inside by described side wall lower ends the lower face that forms by described sidewall upper, described longeron is one time punching molded by alloy material.
Preferably, described crossbeam has a main body of cross-beam and distinguishes extended strength beam by described main body of cross-beam two ends, the cross-sectional area of described strength beam is greater than the cross-sectional area of described main body of cross-beam, described main body of cross-beam two ends are shelved respectively and are fixed on described lower face, and described strength beam respectively butt is fixed on the sidewall of described longeron.
Preferably, described longeron is provided with the some fixed orifices that run through thereon, and described main car frame also comprises by fixed orifice and is fixed on air receiver erection support and the spacing wire rope bracket on described longeron in bolt mode.
Preferably, described alloy material is aluminum alloy materials.
Preferably, described crossbeam number is 2 and separated by a distance.
Compared with correlation technique, the beneficial effects of the utility model are, have alleviated main car frame weight, have strengthened the strength and stiffness of main car frame, and have effectively avoided existing by many sheet material welds or bending forms the concentrated defect of longeron stress; Make main car frame tool distribution of stress and can absorb better the elliptical gear load producing in vehicle traveling process better; Be conducive to handling and the replacing of parts.
[accompanying drawing explanation]
Fig. 1 is the perspective view of the utility model automobile primary vehicle frame.
[specific embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of automobile primary vehicle frame 10, it mainly comprises that two longerons 1 that are oppositely arranged, some air receiver erection supports 2, correspondence are located at some air receivers 3, the plural spacing wire rope bracket 4 on aforementioned bearing 2, at least one crossbeam 5(the present embodiment being fixedly arranged between longeron 1 is preferably two crossbeams 5), the curved air bag air receiver fixed beam 8 of the shrouding 6, limiting stopper 7, the cross-sectional plane that are rectangle, be located at the suspended bearer 9 in longeron 1 outside.
Wherein, described longeron 1 is lengthwise type, system is by extrusion forming of high-strength aluminum alloy material, this longeron 1 tool one sidewall 12 and by these sidewall 12 upper ends direction of crossbeam 5 (away from) vertical upper face 13 forming that extends laterally, by these sidewall 12 lower ends (i.e. the direction of close crossbeam 5) vertical lower face 14 forming that extends to the inside, the longeron 1 of this kind of structure has also strengthened the Rigidity and strength of main car frame 10 in saving material, another this longeron 1 upper face 13 and sidewall 12 do not offer some spacing not etc. and run through fixed orifice 11 thereon, this fixed orifice 11 is bolt hole, thereby described air receiver erection support 2 is matched and is fixed on longeron 1 sidewall 12 inner sides by bolt mode and the corresponding fixed orifice 11 on longeron 1, described air receiver 3 correspondences are set up on aforementioned air receiver erection support 2, same described spacing wire rope bracket 4 is also by fixed orifice 11 corresponding on longeron 1 and is fixed on longeron 1 sidewall 12 inner sides in bolt mode.
Described crossbeam 5 is fixed between two longerons 1 by welding manner, described crossbeam 5 has a main body of cross-beam 51 and distinguishes extended strength beam 52 by described main body of cross-beam 51 two ends, the cross-sectional area of described strength beam 52 is greater than the cross-sectional area of described main body of cross-beam 51, described main body of cross-beam 51 two ends are shelved respectively and are fixed on described lower face 14, described strength beam 52 respectively butt is fixed on the sidewall 12 of described longeron 1, the crossbeam 5 of this kind of structure can increase the rigidity of main car frame 10, make the better distribution of stress of its tool, and then effectively absorb the elliptical gear load producing in vehicle traveling process.
Described shrouding 6 extends and forms obliquely from longeron 1 lower face 14; Described limiting stopper 7 extends from longeron 1 one terminal horizontal; Described air bag air receiver fixed beam 8 is between two longerons 1, and its two ends are erected on respectively on longeron 1 lower face 14; Described suspended bearer 9 is slightly the shape of falling ∏, and is fixedly arranged on longeron 1 sidewall 12 and lower face 14 outsides.
Compared with correlation technique, the girder work of the utility model automobile primary vehicle frame has strengthened the Rigidity and strength of main car frame, and has effectively avoided existing and concentrated by the longeron stress that multi-sheets welds or bending forms, and has the defect of potential safety hazard; The utility model automobile primary cross member of frame structure arranges the rigidity that can further increase main car frame, dispersive stress better, and absorb better the elliptical gear load producing in vehicle traveling process; Other parts such as such as subframe, air receiver, spacing wire rope bracket of the utility model automobile primary vehicle frame are closely fixing by high strength bolt and longeron, and one can avoid stress to concentrate, and the two facilitates handling and the replacing of this type component.The main car frame of aforementioned structure of having is in a word being saved material, when alleviating vehicle frame weight and reduce vehicle frame manufacturing cost, has also effectively promoted the strength and stiffness of vehicle frame, has promoted safety performance.
Above-described is only embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art at this, do not departing under the prerequisite of the utility model creation design; can also make improvement, but these all belong to protection domain of the present utility model.
