Abstract
The utility model discloses a last swing arm structure of double -wishbone independent suspension. The utility model discloses an on reinforcing plate (2) along its base plate (2a) about the whole setting in the sideline A (2b) that bends to weld mainboard (1), bottom plate (3), reinforcing plate (2) become integratively. Make the area of contact between mainboard (1) and reinforcing plate (2) increase to reduce stress, improved whole security of going up the swing arm structure, greatly avoided the emergence of sealing off, fracture phenomenon.
Description
Technical field
This utility model relates to auto parts machinery field, particularly relates to double cross arm independent suspension top link structure.
Background technology
Double cross arm independent suspension is as a kind of advanced suspension, and it has amortisseur and does not has transverse load, and upper end level is relatively low, advantageously reduces headstock height, improves the advantages such as body shape.So that this suspension has good control stability and comfortableness, in car, SUV and racing car, therefore all widely apply this suspension frame structure.Top link is as a vitals of double cross arm independent suspension, and it includes mainboard, interior lining panel, upper plate etc., and above-mentioned parts are welded to each other integral.There is stress raisers phenomenon in current top link, on it, the stress on 5,6 two points respectively reaches 705MPa and 495MPa the most as shown in Figure 6, the safety of the most whole parts has large effect, when trying on road repeatedly above-mentioned 5,6 two there is the dangerous situation such as sealing-off, tear.
Utility model content
In order to overcome drawbacks described above and not enough this utility model offer techniques below scheme: double cross arm independent suspension top link structure, described top link structure includes mainboard, base plate, reinforcing plate, and be welded into a whole, described reinforcing plate includes substrate, described substrate is sector, along the whole bending A being provided with upwards in sideline, described substrate left and right, during welding, described substrate overlays inside described mainboard, the inner surface laminating of the outer surface of described bending A and described mainboard sidewall.
As preferably, described top link structure also includes interior lining panel, described interior lining panel is made up of main part and two dogleg section B, described main part is strip, its bottom surface is integrally welded with the laminating of described reinforcing plate upper surface of base plate, said two dogleg section B is separately positioned on the both ends of described main part end face, and the end face of described two dogleg section B is integrally welded with the laminating of described base plate.The intensity so making whole top link structure is more preferable, safer.
As preferably, on described base plate, the dogleg section B joint place with described interior lining panel is provided with two through holes, and described through hole is kidney-shaped, and the contour line along described through hole is provided with weld seam.When so setting makes to weld, arc welding gun head can be directly protruding in described through hole and complete welding, makes welding more convenient.
Compared with prior art, this utility model have the advantages that by reinforcing plate along the whole bending A that arranges in its sideline, substrate left and right, and by integrally welded to mainboard, base plate, reinforcing plate.Contact area between mainboard and reinforcing plate is increased, thus reduces stress, improve the safety of whole top link structure, greatly avoid the generation of sealing-off, cracking phenomena.

Detailed description of the invention
Below in conjunction with the accompanying drawings, detailed description of the invention of the present utility model is elaborated.
As it is shown in figure 1, described top link structure includes mainboard 1, base plate 3, reinforcing plate 2 and interior lining panel 4.Described reinforcing plate includes substrate 2a, described substrate 2a is sector, along the whole bending A2b being provided with upwards in described substrate about 2a sideline, during welding, described substrate 2a overlays described mainboard 1 inside, the inner surface laminating of the outer surface of described bending A2b and described mainboard sidewall.Described interior lining panel 4 is made up of main part 4a and two dogleg section B4b, described main part 4a is strip, its bottom surface is integrally welded with the laminating of described reinforcing plate 2 substrate 2a upper surface, said two dogleg section B4b is separately positioned on the both ends of described main part 4a end face, and the end face of described two dogleg section B4b is fitted integrally welded with described base plate 3.On described base plate 3, the dogleg section B4b joint place with described interior lining panel 4 is provided with two through hole 3a, and described through hole 3a is kidney-shaped, and the contour line along described through hole 3a is provided with weld seam.
First by integrally welded with reinforcing plate 2 for mainboard 1 during welding, then interior lining panel 4 bottom surface is made to fit with described reinforcing plate 2 substrate 2a upper surface, and it is integrally welded, finally the base plate 3 end face with two dogleg section B4b on interior lining panel 4 will be made to overlap, and base plate 3 is welded into a whole with the most soldered parts, and the weld seam that the contour line completing through hole 3a along base plate 3 is arranged.
Compared with prior art, this utility model have the advantages that by reinforcing plate 2 along its substrate about 2a sideline the whole bending A2b that arranges, and by integrally welded to mainboard 1, base plate 3, reinforcing plate 2 and interior lining panel 4.Contact area between mainboard and reinforcing plate is increased, thus reduces stress.After tested as it is shown in fig. 7, at higher 5,6 liang of original stress its stress improve the intensity of whole top link structure by increasing interior lining panel 4 for 508MPa and 399MPa simultaneously respectively, thus greatly avoid the generation of sealing-off, cracking phenomena.
Below this utility model has been described in detail, but this utility model has been not limited to detailed description of the invention described herein.It will be appreciated by those skilled in the art that in the case of without departing substantially from this utility model scope, may be made that other changes and deformation.Protection domain of the present utility model is defined by the following claims.
