We generally have grooved, I shape, box, cast, zigzag at existing girder construction in length and breadth.At present, grooved section bending strength is large, good manufacturability, and part is installed fastening convenience, causes the installing space in the middle of longeron less but steel spring is installed because of the outer outside of belly.Adopt the longeron of Z-shaped beam section, can strengthen the installing space of parts, but resistance to torsion is poor.
Utility model content
The problem existing for above-mentioned prior art, the utility model object is to provide a kind of Novel longitudinal girder construction that has solved above problem.
The technical solution of the utility model is: a kind of Novel longitudinal girder construction, comprise longeron body, the leading portion of described longeron body is water jacket shaped steel, back segment is " Z " Zee bar steel Z, described longeron body is welded by leading portion and back segment, described " Z " Zee bar steel Z is made up of end plate and the middle vertical connecting panel of upper and lower two levels, the back segment of described longeron body is provided with L shaped brace panel, described L shaped brace panel is made up of horizontal plate and vertical plate, the horizontal plate of described brace panel is concordant with the upper head plate of longeron body back segment, the back-to-back laminating of connecting panel of the vertical plate of described brace panel and longeron body back segment, between described brace panel and longeron body, be welded to each other,
As preferably, the erecting frame of steel plate tail-bracket after the leading portion of described longeron body is provided with and installs;
As preferably, described erecting frame and this body by integral forming of longeron;
As preferably, described brace panel is covered on the leading portion of longeron body and the weld of back segment;
As preferably, the vertical plate of described brace panel is identical with the connecting panel height of longeron body back segment;
As preferably, on the vertical plate of described brace panel, offer multiple circular windows, described brace panel welds along the edge of circular window and the connecting panel of longeron body back segment;
As preferably, the back segment of described longeron body is also provided with strengthen box.
The beneficial effects of the utility model are: adopt the mode of sectional forming, the leading portion of longeron main body is outer-slotted, and back segment is zigzag steel.Add L shaped brace panel, guarantee the intensity at steel plate support place, back segment adds interior grooved strengthen box, the intensity at spring rear support place before guaranteeing.This integral type front rail structure, does not need large molded equipment, and available middle-size and small-size equipment sectional forming reduces and drops into, and reduces costs.Owing to having an overall top airfoil and breadth to do benchmark, parts quality can be guaranteed like a cork.

The specific embodiment
Embodiment: as a kind of embodiment of the present utility model, a kind of Novel longitudinal girder construction as shown in Figures 1 to 5, comprise longeron body, the leading portion 1 of described longeron body is water jacket shaped steel, back segment 2 is " Z " Zee bar steel Z, described longeron body is welded by leading portion 1 and back segment 2, described " Z " Zee bar steel Z is made up of end plate and the middle vertical connecting panel of upper and lower two levels, the back segment 2 of described longeron body is provided with L shaped brace panel 3, described L shaped brace panel 3 is made up of horizontal plate and vertical plate, the horizontal plate of described brace panel 3 is concordant with the upper head plate of longeron body back segment 2, the back-to-back laminating of connecting panel of the vertical plate of described brace panel 3 and longeron body back segment 2, between described brace panel 3 and longeron body, be welded to each other, weld except meeting the place of meeting, on the vertical plate of described brace panel 3, offer multiple circular windows 6, described brace panel 3 welds along the edge of circular window 6 and the connecting panel of longeron body back segment 2, make between vertical plate and connecting panel face and face be connected more firm, the vertical plate of described brace panel 3 is identical with the connecting panel height of longeron body back segment 2, make brace panel 3 using back segment 2 bottom plates of longeron body as support, strengthen the pressure resistance of brace panel 3, the erecting frame 4 of steel plate tail-bracket after the leading portion 1 of described longeron body is provided with and installs, the installation of convenient rear steel plate tail-bracket, described erecting frame 4 and this body by integral forming of longeron, structure stable connection, described brace panel 3 is covered on the leading portion 1 of longeron body and the weld of back segment 2, strengthens the intensity of weld, and back segment 2 adds interior grooved strengthen box 5, and strengthen box 5 is that U-steel is between the bottom plate and brace panel 3 horizontal plates of longeron body back segment 2.
The utility model adopts the mode of sectional forming, and the leading portion 1 of longeron main body is outer-slotted, and back segment 2 is zigzag steel.Add L shaped brace panel 3, guarantee the intensity at steel plate support place, back segment 2 adds interior grooved strengthen box 5, the intensity at spring rear support place before guaranteeing.Compared with U-steel longeron, because back segment 2 automobile equipments are a lot, its upper surface of the utility model is wider convenient places more equipment, and intensity ratio U-steel wants large many.Compared with I shape longeron, lack a lower surface, greatly save interior space, longeron main body back segment 2 this effects a lot of at equipment are even more important, and strengthen by brace panel 3 is set, intensity and insolently with I shape longeron, examination requirement of strength also can add strengthen box 5.Compared with the longeron of zigzag, intensity has significant increase.This integral type front rail structure, does not need large molded equipment, and available middle-size and small-size equipment sectional forming reduces and drops into, and reduces costs.Owing to having an overall top airfoil and breadth to do benchmark, parts quality can be guaranteed like a cork.And can also allow centre of gravity of vehicle decline, increase the stationarity of travelling.
Above a kind of Novel longitudinal girder construction provided by the utility model is carried out to detailed introduction, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, to be possible to change of the present utility model and improvement, and can not exceed design and the scope of accessory claim defined, in sum, this description should not be construed as restriction of the present utility model.
