Abstract
The utility model relates to a rear crossbeam assembly for an automotive rear floor. The rear crossbeam assembly is welded on the automotive rear floor and comprises a rear crossbeam; an oil box supporter is welded at each of two positions on the front side surface of the rear crossbeam, close to two ends of the rear crossbeam; a middle bracket is welded in the middle part on the rear side surface of the rear crossbeam; and the cross section of the oil box supporter and the middle bracket are U-shaped structures with flanging. After the rear crossbeam assembly is welded on the rear floor, the rear floor has higher strength and stiffness, and the torsion and mode of a lower vehicle body can be better improved.
Description
Technical field
The utility model relates to a kind of auto parts and components, particularly the automobile rear floor rear cross beam assembly.
Background technology
Back floor after cross member is the parts that are welded on the automobile rear floor, and its effect is strength and stiffness of strengthening automobile rear floor, improves reversing and mode of vehicle body.After cross member generally is " one " font, and its cross-sectional plane is the U-shaped with flange, and after cross member welds by described flange and floor, back, the longeron welding of the two ends of after cross member and both sides, floor, back.After cross member adopts the cold-rolling steel-plate punch of 1.0mm-1.5mm to form, it is simple in structure, but can not strengthen the strength and stiffness on floor, back preferably, and can not improve reversing and mode of vehicle body preferably, thereby the strength and stiffness of lower body are strengthened, for this reason, must design the strength and stiffness that some supports or reinforcement increase lower body separately.
Summary of the invention
The purpose of this utility model provides a kind of automobile rear floor rear cross beam assembly, be welded on it on floor, back after, can strengthen the strength and stiffness of automobile rear floor, improve reversing and mode of vehicle body.
Automobile rear floor rear cross beam assembly described in the utility model, comprise after cross member, the cross-sectional plane of after cross member is the U-shaped with flange, leading flank at after cross member respectively is welded with a fuel tank bearing near after cross member end positions place, trailing flank middle part at after cross member is welded with medium-height trestle, and the cross-sectional plane of fuel tank bearing and medium-height trestle all is the U-shaped with flange.
Be welded with end junction at the after cross member two ends, the shape of cross section of end junction is consistent with the after cross member shape of cross section.
On two fuel tank bearings, be welded with the tank hanger that is " several " font.
Be welded on the fuel tank bearing of after cross member leading flank near the end positions place, and be welded on the medium-height trestle at after cross member trailing flank medium position place, make rear cross beam assembly form " six " font structure, each part cross section all is the U-shaped with flange in addition, be welded on and form closing structure on the automobile rear floor, so can effectively strengthen the strength and stiffness on floor, back, improve reversing and mode of vehicle body.
The end junction usable intensity of after cross member two ends welding and rigidity sheet material are preferably made, but after cross member then working strength and the relatively poor material of rigidity, thus can effectively reduce the cost of rear cross beam assembly.
The tank hanger that welds on two fuel tank bearings can be used for installing automotive oil tank.
Automobile rear floor rear cross beam assembly described in the utility model is owing to have this kind structure, after being welded on the floor, back, compare, can make the floor, back have higher strength and stiffness with existing after cross member, and can improve reversing and mode of lower body preferably, and has favorable manufacturability.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the axonometric drawing of automobile rear floor rear cross beam assembly described in the utility model.
Fig. 2 is the exploded view of this automobile rear floor rear cross beam assembly.
Fig. 3 is that this automobile rear floor rear cross beam assembly is welded on the constitution diagram on the automobile rear floor.
The specific embodiment
As depicted in figs. 1 and 2, this automobile rear floor rear cross beam assembly comprises the after cross member 3 that is " one " font, the cross-sectional plane of after cross member 3 is the U-shaped with flange, is welded with end junction 1 at the two ends of after cross member 3, and the shape of cross section of end junction 1 is consistent with after cross member 3 shape of cross sections.Leading flank at after cross member 3 respectively is welded with a fuel tank bearing 5 near after cross member end positions place, on two fuel tank bearings 5, be welded with the tank hanger 4 that is " several " font, the trailing flank middle part of after cross member 3 is welded with medium-height trestle 2, and the cross-sectional plane of fuel tank bearing 5 and medium-height trestle 2 all is the U-shaped with flange.
As shown in Figure 3, the flange of this automobile rear floor rear cross beam assembly by its each parts is welded on the automobile rear floor 7, and simultaneously with the end junction 1 at after cross member 3 two ends respectively with longeron 6 welding of 7 both sides, floor, back, thereby realize the welding of this rear cross beam assembly on automobile rear floor 7.
Claims (3)
1. automobile rear floor rear cross beam assembly, comprise after cross member (3), the cross-sectional plane of after cross member is the U-shaped with flange, it is characterized in that: the leading flank at after cross member respectively is welded with a fuel tank bearing (5) near after cross member end positions place, trailing flank middle part at after cross member is welded with medium-height trestle (2), and the cross-sectional plane of fuel tank bearing and medium-height trestle all is the U-shaped with flange.
2. according to the described automobile rear floor rear cross beam assembly of claim 1, it is characterized in that: be welded with end junction (1) at after cross member (3) two ends, the shape of cross section of end junction is consistent with the after cross member shape of cross section.
3. according to claim 1 or 2 described automobile rear floor rear cross beam assemblies, it is characterized in that: on two fuel tank bearings (5), be welded with the tank hanger (4) that is " several " font.
