Abstract
The utility model discloses a beam body of a twisted beam hanger bracket. The beam body comprises a circular steel tube which is provided with an opening (1) along the length direction. A smooth circular-arc-shaped structure is arranged from two ends of the opening (1) to the middle of the opening (1). The distance from the middle of the opening to the central line of the steel tube is smallest and is 1/5 of the radius of the steel tube. The opening (1) is formed by laser cutting. According to the beam body of the twisted beam hanger bracket, by adoption of the structure, the opening is formed in the middle of the beam body, a certain twisting deformation of the beam body is allowed to be realized, correlation of left wheel hop and right wheel hop is weakened, sitting comfort of a back row is improved, meanwhile, and two sections can provide a larger welding area, and therefore strength and reliability of the twisted beam are improved.
Description
Technical field
The utility model relates to a kind of cross-beam body of torsion beam suspension.
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 that a kind of cross-beam body of torsion beam suspension is provided 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 the cross-beam body of this kind torsion beam suspension comprises circular steel pipe, described steel pipe offers opening along the length direction of steel pipe, and opening is smooth arc-shaped structure from two ends to the middle part of opening, and the middle part of opening is minimum apart from the distance of the line of centers of steel pipe.
The middle part of described opening is 1/5 of steel pipe radius apart from the distance of the line of centers of steel pipe.
Described opening adopts laser beam cutting to form.
Has the cross-beam body of this kind torsion beam suspension of said structure by at the midway location opening of 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: 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.The cross-beam body of this kind torsion beam suspension comprises circular steel pipe, described steel pipe offers opening 1 along the length direction of steel pipe, and opening 1 is smooth arc-shaped structure from two ends to the middle part of opening 1, the middle part of opening 1 is minimum apart from the distance of the line of centers of steel pipe, the middle part of opening 1 is 1/5 of steel pipe radius apart from the distance of the line of centers of steel pipe, and opening 1 adopts laser beam cutting to form.
The cross-beam body of this kind torsion beam suspension is 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.
