The technical problems to be solved in the utility model is to overcome the high and defect that cost performance is low of torsion beam rear axle crossbeam complex process in prior art, price, providing a kind of automobile torsion beam rear axle crossbeam.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of automobile torsion beam rear axle crossbeam, comprise cross-beam body, its feature is, the dual-side of described cross-beam body outwards turns down formation flange, make the center cross-sectional of described cross-beam body be U-shaped, the center width of described cross-beam body is less than two ends width.
Preferably, the width of described flange reduces along the two ends of described cross-beam body gradually to center.
Preferably, the angle between the described flange of described cross-beam body both sides is 10 °-25 °.
Preferably, the two ends width of described cross-beam body is 1.2 times of center width to 2.2 times.
Preferably, the two ends of described cross-beam body offer knock hole.
Preferably, the two ends of described cross-beam body offer multiple lightening hole.
Positive progressive effect of the present utility model is: crossbeam central cross-section is set to U-shaped structure by the utility model automobile torsion beam rear axle crossbeam, and the flange of crossbeam is designed according to distribution of stress, the problem of punching press flange bounce-back can be controlled like this by the angle reducing mould.In addition, the technique of this crossbeam is simple, only needs to carry out blanking, punching is held concurrently in trimming, shaping.

Detailed description of the invention
Preferred embodiment of the present utility model is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 4 is the connection structure schematic diagram of the utility model automobile torsion beam rear axle crossbeam for torsion beam rear axle.As shown in Figure 4, the utility model automobile torsion beam back axle 20 comprises two trailing arms 22 and cross-beam body 21, cross-beam body 21 connects the trailing arm 22 being positioned at two ends, and torsion beam rear axle 20 realizes the connection between vehicle body after press-fiting rubber bush by the lining pipe 23 of trailing arm 22 front end.
Fig. 5 is the block diagram of the utility model automobile torsion beam rear axle crossbeam.Fig. 6 is along the cutaway view that B-B line is cut open in Fig. 5.As shown in Figure 5 and Figure 6, especially, the dual-side of cross-beam body 21 outwards turns down and forms flange 211,212, make the center cross-sectional of cross-beam body 21 be U-shaped thus, and the center width of cross-beam body 21 is less than two ends width.Especially, the angle C between the flange 211,212 of cross-beam body 21 both sides is 10 °-25 °, is preferably 10 °, 20 ° or 25 °.Such torsion beam rear axle crossbeam just can control the problem of punching press flange bounce-back in the course of processing by the angle reducing mould.
Fig. 7 is the lateral plan of the utility model automobile torsion beam rear axle crossbeam.As shown in Figure 7, further, enlarging process is carried out at the two ends of cross-beam body 21, the two ends width a1 by cross-beam body 21 is set to 1.2 times of center width a2 to 2.2 times, can reduce the stress of crossbeam and trailing arm junction like this.
Fig. 8 is the front view of the utility model automobile torsion beam rear axle crossbeam.As shown in Figure 8, according to stress analysis, the centre portion stress of usual cross-beam body 21 is little, and the stress at two ends is large.Therefore according to distribution of stress, the two ends of the width of the flange (as shown in Figure 8 flange 212) of cross-beam body 21 along cross-beam body 21 are reduced gradually to center.This flange is carried out two ends prolongation, the middle mode shortened can reduce crossbeam weight effectively.
Fig. 9 is the birds-eye view of the utility model automobile torsion beam rear axle crossbeam.As shown in Figure 9, further preferably, the two ends of cross-beam body 21 offer knock hole 214, so that location, thus plane and two pits Benchmark System can be formed, make location more stable.In addition, the two ends of cross-beam body 21 offer multiple lightening hole 215, effectively alleviates the weight of cross-beam body 21 with this.
In sum, the utility model automobile torsion beam rear axle crossbeam adopts the open-ended cross piece of sheet profile, crossbeam central cross-section is set to U-shaped structure, and designs the flange of crossbeam according to distribution of stress, the problem of punching press flange bounce-back can be controlled like this by the angle reducing mould.In addition, the technique of this crossbeam is simple, only needs to carry out blanking, punching is held concurrently in trimming, shaping.
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.
