Abstract
The utility model discloses a torsion beam suspension cross beam structure for an automobile. The torsion beam suspension cross beam structure for the automobile comprises a cross beam body (1), wherein the cross beam body (1) is a round steel pipe. An opening (2) is formed in the steel pipe along the length direction of the steel pipe, the cross section of the opening (2) is of a rectangle shape, the distance from the bottom of the rectangle opening (2) to the center line of the steel pipe is two-thirds of the radius of the steel plate, and the opening (2) is cut by laser. The opening (2) is formed in the position of the middle of the cross beam body so that certain torsion deflection deformation of the cross beam body can be achieved, and jumping correlation of a left wheel and a right wheel is weakened, and riding comfort of a rear row is improved. Meanwhile, two cross sections can provide large welding areas, so that strength and reliability of a torsion beam are improved.
Description
Technical field
The utility model relates to a kind of automobile torsion beam suspension beam structure.
Background technology
Torsion beam suspension is widely used in preposition forerunner's vehicle.Compare other suspensions, torsion beam suspension has some very apparent advantages: make simply, lightweight, cost is low.Torsion beam suspension is common in A00, A0, A rank car, and torsion beam suspension consists of by the vertical towing arms of putting of two of beam weldings, and its center member is topmost component part wherein.When satisfying vehicle roll, the control that catenary motion and longitudinal movement can obtain expecting, crossbeam is designed to the opening form of V, U-shaped shape more.
Modal torsion beam cross-beam body is a block plate, structure as shown in Figure of description 1 and 2.Suitable punching press can realize the opening of torsion beam, because the cross section of steel plate is less, in actual use, the phenomenon of cross-beam body two ends cracking often occurs, reinforces even added auxiliary welded blank, still can not well deal with problems.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of automobile torsion beam suspension beam structure for problems of the prior art, its objective is and allowing that cross-beam body realizes under the prerequisite of certain torsional deflection, weaken the correlativity that left and right wheels is beated, the traveling comfort that after improving, row takes.
The technical solution of the utility model is that this kind automobile comprises cross-beam body with torsion beam suspension beam structure beam structure, cross-beam body is round steel pipe, length direction along steel pipe on described steel pipe offers two openings, two openings are symmetrically distributed on the surface of steel pipe, and the cross section of opening is rectangle.
The distance of the line of centers of the distance from bottom steel pipe of described rectangular aperture is 2/3 of steel pipe radius.
Described opening adopts laser beam cutting to form.
This kind automobile with said structure uses the torsion beam suspension beam structure by the midway location opening at cross-beam body, can allow that cross-beam body realizes certain torsional deflection, weaken the correlativity that left and right wheels is beated, the traveling comfort that after improving, row takes, two sections can provide larger bonding area simultaneously, thereby improves intensity and the reliability of torsion beam.
Description of drawings
Below in conjunction with accompanying drawing, utility model is described further:
Fig. 1 is the structural representation of prior art.
Fig. 2 is the left view of structure shown in Figure 1.
Fig. 3 is the structural representation of utility model.
Fig. 4 is the birds-eye view figure of structure shown in Figure 3.
In Fig. 1-4,1: cross-beam body; 2: opening.
The specific embodiment
Fig. 1-2 is depicted as the structural representation of prior art.Suitable punching press can realize the opening of torsion beam, because the cross section of steel plate is less, in actual use, the phenomenon of cross-beam body two ends cracking often occurs, reinforces even added auxiliary welded blank, still can not well deal with problems.
Fig. 3-4 are structural representation of the present utility model.This kind automobile comprises cross-beam body 1 with torsion beam suspension beam structure beam structure, cross-beam body 1 is round steel pipe, offer 2, two openings 2 of two openings along the length direction of steel pipe on described steel pipe and be symmetrically distributed on the surface of steel pipe, and the cross section of opening 2 is rectangle.
The distance of the line of centers of the distance from bottom steel pipe of rectangular aperture 2 is 2/3 of steel pipe radiuses, and opening 2 adopts laser beam cutting to form.
This kind automobile uses the torsion beam suspension beam structure by the midway location opening at cross-beam body, can allow that cross-beam body realizes certain torsional deflection, weaken the correlativity that left and right wheels is beated, the traveling comfort that after improving, row takes, two sections can provide larger bonding area simultaneously, thereby improves intensity and the reliability of torsion beam.
