Abstract
The utility model provides a rear axle cross beam of automobile torsion beam, rear axle cross beam of automobile torsion beam is the opening crossbeam of panel type, the both sides limit of crossbeam is equipped with the turn -ups respectively, the turn -ups is to the book that turns up. The utility model discloses rear axle cross beam of automobile torsion beam's simple structure can satisfy the technical requirement and the cost requirement of economic motorcycle type well.
Description
Technical field
The utility model relates to automotive field, particularly a kind of automobile torsion beam rear axle crossbeam.
Background technology
In automotive field, in existing market, car chassis adopts the version of torsion beam rear axle to get more and more, and the structural requirement for automobile torsion beam back axle is also more and more higher.Fig. 1 is the structural representation of orthodox car torsion beam rear axle, and as shown in Figure 1, orthodox car torsion beam rear axle 10 connects two ends trailing arm 12 by crossbeam 11, press-fits rubber bush by the lining pipe 13 of trailing arm 12 front end, then realizes the connection between vehicle body.Realize, with the connection of wheel, coordinating coil spring with bracket assy., spring seat 15 by the axle journal connecting panel 14 of trailing arm 12 rear end.Damper bracket 16 coordinates shock absorber to realize being connected with the soft of vehicle body, to reach the effect of vibration damping and support tare.
The integral structure that this automobile reverses back axle is simply compact, and compare the independent suspension of multi link formula and numerous connecting rod, it takes up room less, more space can be used for arranging rear space and boot compartment, effectively can reduce the height of car bottom plate.And, this automobile reverse back axle design difficulty, research and development cost, manufacturing cost etc. compare independent suspension also has greater advantages.So torsion beam rear axle is widely used on the SUV of low and middle-end family-sized car and low side.
Fig. 2 is the structural representation of orthodox car torsion beam rear axle center member.As shown in Figure 2, the crossbeam 11 that this back axle adopts is the sheet profile open-ended cross piece of V-type band parallel edges 111.When actual stand test, the not good crossbeam that usually can cause of the surface quality of punching press end face ftractures.Therefore, the crossbeam in traditional automobile torsion beam back axle is urgently in improving.
Utility model content
The technical problems to be solved in the utility model is to overcome the defect that in prior art, automobile torsion beam back axle center member easily ftractures, and provides 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, its feature is, described automobile torsion beam rear axle crossbeam is the open-ended cross piece of sheet profile, and the dual-side of described crossbeam is respectively equipped with flange, and described flange outwards turns down.
Preferably, the shearing radius in the middle part of described crossbeam is 900-1000mm.
Preferably, described flange is arranged on the 40-80mm place apart from described crossbeam both sides end face.
Preferably, the length of described flange is 14-18mm.
Preferably, described crossbeam is V-shaped.
Positive progressive effect of the present utility model is: the structure of the utility model automobile torsion beam rear axle crossbeam is simple, can meet technical requirements and the cost requirement of economic vehicle well.
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 orthodox car torsion beam rear axle.
Fig. 2 is the structural representation of orthodox car torsion beam rear axle center member.
Fig. 3 is the front view of the utility model automobile torsion beam rear axle crossbeam.
Fig. 4 is the birds-eye view of the utility model automobile torsion beam rear axle crossbeam.
Fig. 5 is the lateral plan of the utility model automobile torsion beam rear axle crossbeam.
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. 3 is the front view of the utility model automobile torsion beam rear axle crossbeam.Fig. 4 is the birds-eye view of the utility model automobile torsion beam rear axle crossbeam.Fig. 5 is the lateral plan of the utility model automobile torsion beam rear axle crossbeam.
As shown in Figures 3 to 5, disclose a kind of automobile torsion beam rear axle crossbeam 20 in an embodiment of the present utility model, it is set to the open-ended cross piece of sheet profile.Be respectively equipped with flange 21 at the dual-side of crossbeam 20, and flange 21 outwards turns down.
Further, the shearing radius 22 in the middle part of crossbeam 20 is 900-1000mm.Flange 21 is arranged on the 40-80mm place of distance crossbeam 20 both sides end face.
Preferably, the length of flange 21 is 14-18mm, and crossbeam 20 is V-shaped.
Describe according to said structure, the thickness of slab of the utility model automobile torsion beam rear axle crossbeam is than traditional reduced thickness 0.4mm.According to the result of simulation analysis of computer, its cross section improves the crossbeam torsional stiffness of 7.7%, and little for weight.In actual stand test, without crossbeam cracking phenomena under same load.The structure of the utility model automobile torsion beam rear axle crossbeam is simple, can meet technical requirements and the cost requirement of economic vehicle well.
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.
Claims (5)
