Detailed description of the invention
The technical matters solved to make the utility model, technical scheme and beneficial effect are clearly understood, below in conjunction with drawings and Examples, are described in further detail the utility model.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 2, shown in Fig. 3 and Fig. 5, the vehicle front suspension control arm that the utility model one embodiment provides comprises main body steel plate 1, ball end assembly 2, front lining assembly 3, back bush assembly 4 and reinforcement dull and stereotyped 5, described main body steel plate 1 is shaping by single steel plate integrated punching, described ball end assembly 2 is arranged on one end of described main body steel plate 1, described back bush assembly 4 is arranged on the other end of described main body steel plate 1, described front lining assembly 3 is arranged in the outer side edges in the middle part of described main body steel plate 1, described main body steel plate 1 is formed with the semiclosed cavity 10 to a side opening, described reinforcement dull and stereotyped 5 is welded in described semiclosed cavity 10.
In the present embodiment, as shown in Figure 5, described main body steel plate 1 comprises the reinforced rib 11 caving inward formed by a side surface of described main body steel plate 1 and the flange 12 being formed in described reinforced rib 11 both sides, and described reinforced rib 11 surrounds with described flange 12 and forms described semiclosed cavity 10.
In the present embodiment, described reinforcement dull and stereotyped 1 covers the opening of described semiclosed cavity 10 completely.The area of the reinforcement flat board 5 namely shown in Fig. 3 is more than or equal to the sectional area of the opening of described semiclosed cavity 10.
In the present embodiment, the described cross sectional shape strengthening the dull and stereotyped outer contour shape of 5 and the opening of described semiclosed cavity 10 matches.
In the present embodiment, as shown in Figure 5, the bottom of described reinforced rib 11 is a flat board.The described both sides strengthening flat board 5 are welded on corresponding described flange 12, and described bottom (flat board) interval strengthening flat board 5 and described reinforced rib 12 is arranged.Like this, strengthen due to described the opening that dull and stereotyped 1 covers described semiclosed cavity 10 completely, after thus strengthening dull and stereotyped 5 welding, obtain enclosed cavity, improve the load-carrying capacity of Control arm.Meanwhile, strengthen, between dull and stereotyped 5 and reinforced rib 12, there is gap value, be conducive to the bending stiffness improving Control arm cross section.
Certainly, in other embodiments, the reinforcement of other form also can be had dull and stereotyped.
As shown in Fig. 1, Fig. 4 and Fig. 5, for the reinforcement of another kind of form is dull and stereotyped, be with difference embodiment illustrated in fig. 3, reinforcement flat board 5 is herein that the specific load (non-ultimate load) that meets adopting optimal way to obtain requires lower reinforcement flat board, its by topological optimization under the front and back meeting intensity and performance requriements, take into account lightweight requirements, namely the opening that dull and stereotyped 5 do not cover described semiclosed cavity 10 completely in length is strengthened, namely the reinforcement shown in relative Fig. 3 is dull and stereotyped, and the reinforcement flat board shown in Fig. 4 is shorter.In Fig. 1, strengthening dull and stereotyped 5 is dotted portion, namely can't see from the visual angle of Fig. 1 and strengthens dull and stereotyped 5.
Fig. 6 and Figure 7 shows that the reinforcement of another kind of form is dull and stereotyped, be with Fig. 4 and difference embodiment illustrated in fig. 5, the area strengthening dull and stereotyped 5 reduces further, described flat board 5 of strengthening only has side to be welded on corresponding described flange 12, opposite side is unsettled, and the dull and stereotyped side surface of 5 of described reinforcement and bottom (flat board) seamless welding of described reinforced rib 12, namely amount very close to each other between dull and stereotyped 5 and reinforced rib 12 is strengthened, like this, semi-closed structure is formed in Control arm, situation that the present embodiment is applicable to reduce further in carrying reinforcement demand (relative to Fig. 4 and embodiment illustrated in fig. 5).
According to the vehicle front suspension control arm of the utility model above-described embodiment, main body steel plate is shaping by single steel plate integrated punching, main body steel plate is formed with the semiclosed cavity to a side opening, and it is dull and stereotyped to be welded with reinforcement in described semiclosed cavity, thus the strength and stiffness of Control arm can be increased, promote the intensity of Control arm under complexity carrying operating mode and the reliability of performance, and, can be dull and stereotyped by the reinforcement that design is multi-form, make the structural strength under Control arm adaptation different automobile types configuration weight and performance requriements.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
