Rear wheel cover tie-beam structure
Technical field
The utility model belongs to the technical field of automobile design and manufacture, and in particular, the utility model relates to a kind of rear wheel cover tie-beam structure.
Background technology
As shown in Figure 1, body mounts 11 place of rear shock absorber of the prior art is subject to impact load frequently, current path, power transmission side is upwards conducted to gusset after passing to rear shock absorber extension board 3 by rear shock absorber brace panel 2, the Path of Force Transfer of attachment point is generally Z-direction conduction, such rear shock absorber brace panel and rear shock absorber extension board stressed very large, cause rear shock absorber brace panel 2 and rear shock absorber extension board 3 easily to produce fatigue cracking.
Utility model content
In order to solve above-mentioned technical matters of the prior art, the purpose of this utility model is the structure providing a kind of rear wheel cover tie-beam that can effectively avoid vehicle body to ftracture.
To achieve these goals, the utility model have employed following technical scheme:
A kind of rear wheel cover tie-beam structure, comprise rear shock absorber brace panel and rear shock absorber extension board, it is characterized in that: also comprise rear shock absorber brace panel tie-beam, described rear shock absorber brace panel tie-beam presents the L shape integral structure with fillet, and have a few glyph construction near the integrally-built first end of described L shape, described a few glyph construction is connected with described rear shock absorber extension board by bolt with side in bottom surface; Near zone and the rear shock absorber brace panel of close described L shape integral structure first end are bolted; There is near integrally-built second end of described L shape concave shape structure, and be bolted cross-beam connecting plate, floor crossmember and floor on the both sides that described concave shape constructs.
Compared with prior art, rear wheel cover tie-beam structure described in the utility model has following beneficial effect:
Rear wheel cover tie-beam structure of the present utility model is bolted rear shock absorber extension board and rear Floor rear crossbeam and rear Floor rear crossbeam connecting panel and rear floor, and the power that rear shock absorber brace panel can be made to be subject to can not only be conducted to Z-direction, also can conduct to Y-direction.Structure of the present utility model is applicable to the new model such as car, SUV.

Detailed description of the invention
Be further elaborated below with reference to the structure of specific embodiment to rear wheel cover tie-beam described in the utility model, to help, those skilled in the art conceives utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
Embodiment 1
As shown in Figure 2-5, the structure of the rear wheel cover tie-beam described in the present embodiment, comprise rear shock absorber brace panel 2 and rear shock absorber extension board 3, add rear shock absorber brace panel tie-beam 1 in addition, described rear shock absorber brace panel tie-beam 1 presents the L shape integral structure with fillet, and have a few glyph construction near the integrally-built first end of described L shape, described a few glyph construction is connected with described rear shock absorber extension board 3 by bolt with side in bottom surface; Near zone and the rear shock absorber brace panel 2 of close described L shape integral structure first end are bolted; There is near integrally-built second end of described L shape concave shape structure, and be bolted cross-beam connecting plate 4, floor crossmember 5 and floor 6 on the both sides that described concave shape constructs.The impact load of the rear shock absorber that the structure of the present embodiment makes vehicle body be subject to adds a conducting path, and load obtains dispersion, can prevent the fatigue cracking of rear shock absorber brace panel and rear shock absorber extension board junction; And add the joint coupling stiffness of rear shock absorber installation place, rigidity and the mode of car load can be promoted significantly, increase operational stability and reduce vibrating noise; Also make the load at rear overhang bumper place be disperseed in addition, so it is thick to lower the be correlated with material of stressed part of rear overhang bumper, reduces tare, reduce costs.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
