Abstract
The utility model aims to provide a one-sheet type variable-cross-section torsion beam to improve the advantages of a beam of a torsion beam rear bridge. The torsion beam rear bridge beam is characterized in that the torsion beam rear bridge beam is of a one-sheet type structure, the lengths of the transverse cross sections are the same, the transverse cross section of the middle portion is in a U shape, and the two end portions of the transverse cross section of the middle portion are in a V shape.
Description
Technical field
The utility model relates to torsion beam back axle crossbeam.
Background technology
Back axle is important safety part and the load member in the car chassis system, and its intensity, rigidity, fatigue etc. have high requirement, are bearing braking, side direction and vertical load in running car.The intensity of back axle, rigidity, fatigue etc. directly have influence on safety, handling stability of car load etc.
Tradition stamping-welded torsion beam rear axle structure is welded by the various brace panels of crossbeam, suspension arm, connecting panel, spring perch, mounting bracket of shock absorber, sleeve and design.
Its center member is divided into U-shaped beam and the one chip V-type beam of one chip band flange, and the torsional stiffness of crossbeam all is directly proportional to its manufacturing cost and car load handling stability.
Torsion beam rear-axle welding assembly is generally used in the design of A0, A1 level car, therefore its cost control requirement is high.Adopt the back axle of one chip V-type beam to have that rigidity is low, the poor defect of operation stability; Adopt the back axle of the U-shaped beam of one chip to have Heavy Weight, defect that cost is high, but its rigidity is large, handling stability can be good.
The utility model content
The purpose of this utility model is to provide a kind of one chip variable section to reverse crossbeam, with the advantage of the crossbeam that promotes the torsion beam back axle.
Torsion beam back axle crossbeam of the present utility model, be characterized in, is one-piece construction, and all lateral cross section are isometric, and the middle part lateral cross section is U-shaped and the both ends lateral cross section is V-arrangement.
Described torsion beam back axle crossbeam, wherein, formed by the belt steel material of natural round edge.
Described torsion beam back axle crossbeam, wherein, the width of the lateral cross section of the lateral cross section of middle U-shaped and the V-arrangement of end is than being 0.6-0.8.
The utility model has some benefits of U-girder, V-arrangement crossbeam concurrently, and advantage and disadvantage of the present utility model will have more detailed description in aftermentioned.
The accompanying drawing explanation
The axle that Fig. 1 is torsion beam back axle crossbeam measures intention.
The transverse sectional view that Fig. 2 is A place in Fig. 1.
Fig. 3 is the transverse sectional view at B place in Fig. 1.
The specific embodiment
As shown in Figure 1, according to the girth variable section crossbeam such as be one chip of the torsion beam back axle crossbeam in embodiment of the present utility model, adopt nature round edge sheet material to form, its structure as shown in Figures 2 and 3, middle part adopts U-shaped cross section that cross section efficiency is higher to improve torsional stiffness, and both sides adopt the V-type cross section to increase the support strength of crossbeam and suspension arm.Section width is by cross section type and the decision of sheet material width, and the width ratio in YuVXing cross section, general U-shaped cross section is about 0.6-0.8; In the girths such as the cross section employing design (developed width is identical) of design center member, be used in conjunction with the belt steel material of nature round edge, make the crossbeam both sides of the edge there is unstressed concentrated characteristic, make in structure design to cancel the local flange of both sides, simplify technique.
Embodiment as shown in the figure has high stock utilization, does not consider lightening hole, and stock utilization can reach 100%.
Embodiment as shown in the figure can effectively improve torsional stiffness and the fatigue life of torsion beam back axle, and its performance exceeds traditional horizontal structure of U-shaped beam, and crossbeam weight can reduce by 25% left and right, has the characteristics of low-cost and high-performance.
Embodiment as shown in the figure adopts the novel girth variable section crossbeams such as one chip, and when reaching U-shaped crossbeam performance, its quality can reduce by 25%, stock utilization can reach 100% substantially, work simplification, have the low-cost and high-performance advantage, can effectively realize lightweight and the low cost of car load.
