Four, this structure is heavier, and raw MAT'L drops into larger.
Utility model content
The technical problems to be solved in the utility model is to overcome in prior art the easy welding deformation of side bar after subframe, and raw MAT'L drops into the defects such as larger, provides side bar after a kind of subframe.
The utility model solves above-mentioned technical matters by following technical proposals: side bar after a kind of subframe, its feature is, after described subframe, side bar is that integral type is shaping, and the thickness of side bar is 2.3mm after described subframe, after described subframe, the inner side Control arm mounting hole of side bar is middle is provided with reinforced rib, and described reinforced rib is step.
Preferably, the shoulder height difference of described reinforced rib is 6.3mm.
Preferably, after the lower surface of described reinforced rib and described subframe, the rear attachment face of the Control arm of side bar is coplanar.
Preferably, described reinforced rib extends to the feature holes place of the rear end of side bar after described subframe.
Preferably, after described subframe, the front outside of side bar is provided with the first change chamfering, and described first becomes chamfering transits to radius 15mm by radius 35mm, then seamlessly transits to radius 35mm.
Preferably, after described subframe, the interlude outside of side bar is provided with the second change chamfering, and described second becomes chamfering transits to radius 6mm by radius 15mm, then seamlessly transits to radius 22mm.
Preferably, after described subframe, the interlude of side bar and described reinforced rib junction are provided with the 3rd and become chamfering, and the described 3rd becomes chamfering is seamlessly transitted to radius 13mm by radius 6mm.
Preferably, the interlude after described subframe between the front mounting hole of the inner side Control arm of side bar and rear mounting hole is provided with boss.
Preferably, the height of described boss is 3mm, and width is 20mm.
Positive progressive effect of the present utility model is:
After the utility model subframe, side bar not only increases the local stiffness of subframe, more effectively improves the fatigue life of subframe assembly.Above less input at raw MAT'L (sheet material, Lamination mould, welding wire) for the more traditional side bar of described subframe side bar, and stock utilization is than front improve about 3%.In addition, after described subframe, side bar also has that quality is light, location is convenient and rigidity high.
Accompanying drawing explanation
The above and other feature of the utility model, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 is the structural representation of traditional subframe side bar.
Fig. 2 is the structural representation of the utility model subframe side bar.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, therefore the utility model is not by the restriction of following public specific embodiment.
Fig. 2 is the structural representation of the utility model subframe side bar.
As shown in Figure 2, disclose side bar 20 after a kind of subframe in an embodiment of the present utility model, it is set to integral molding.After subframe herein, the thickness of side bar 20 is 2.3mm.
After subframe in the present embodiment, side bar 20 makes in order to single piece type by traditional three-chip type, 4.2mm, 1.9mm, 2.1mm is respectively compared to traditional side bar intermediate, side bar rear panel, positioning datum support thickness of slab, total weight is 2.3Kg, after described subframe, the thickness of side bar 20 is set to 2.3mm, and its total weight is 1.66Kg.Total mass alleviates 0.64Kg, then after two subframes, side bar (left and right both sides) alleviates 1.28Kg altogether, and namely total weight alleviates 27.8%.After the utility model subframe, side bar is compared with traditional side bar, and less input for its raw MAT'L (sheet material, Lamination mould, welding wire), and stock utilization is than front improve about 3%.
Meanwhile, after subframe, the inner side Control arm mounting hole of side bar 20 is middle is provided with reinforced rib 21, and reinforced rib 21 is set to step, and the shoulder height difference of reinforced rib 21 is 6.3mm.After the lower surface of reinforced rib 21 and subframe, the rear attachment face of the Control arm of side bar 20 is coplanar, highly constant above, makes reinforced rib 21 extend to feature holes 22 place of the rear end of side bar 20 after subframe.
Further, after subframe, the front outside of side bar 20 arranges the first change chamfering 23, first change chamfering 23 and transits to radius 15mm by radius 35mm, then seamlessly transits to radius 35mm.After subframe, the interlude outside of side bar 20 arranges the second change chamfering 24, second change chamfering 24 and transits to radius 6mm by radius 15mm, then seamlessly transits to radius 22mm.After subframe, the interlude of side bar 20 and reinforced rib 21 junction are provided with the 3rd and become chamfering 25, and the 3rd becomes chamfering 25 is seamlessly transitted to radius 13mm by radius 6mm.
In addition, after subframe side bar 20 inner side Control arm before interlude between mounting hole 26 and rear mounting hole 27 is provided with boss 28.Here boss 28 is highly preferably 3mm, and width is preferably 20mm.
In sum, after the utility model subframe, side bar not only increases the local stiffness of subframe, more effectively improves the fatigue life of subframe assembly.Above less input at raw MAT'L (sheet material, Lamination mould, welding wire) for the more traditional side bar of described subframe side bar, and stock utilization is than front improve about 3%.In addition, after described subframe, side bar also has that quality is light, location is convenient and rigidity high.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
