Abstract
The invention discloses a beam body of an automotive torsion beam suspension. The beam body comprises a circular steel tube, wherein an opening (1) is formed in the steel tube in the length direction of the steel tube, smooth arc-shaped structures are formed between the middle part of the opening (1) and the two ends of the opening, the distance between the middle part of the opening (1) and the central line of the steel tube is minimal and is two thirds of the semidiameter of the steel tube, and the opening (1) is formed by laser cutting. According to the beam body of the automotive torsion beam suspension with the structure, the opening is formed in the beam body to admit the certain torsional deformation of the beam body, so that the correlation of the bouncing of left and right wheels can be weakened, and the riding comfort of the back rows can be improved; meanwhile, larger welding areas of two sections can be provided, so that the strength and reliability of the torsion beam can be improved.
Description
Technical field
The present invention relates to the cross-beam body of a kind of automobile 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: manufacture simply, lightweight, cost is low.Torsion beam suspension is common in A00, A0, A rank car, and torsion beam suspension consists of the vertical towing arms of putting of two of beam weldings, and its center member is topmost component part wherein.When meeting vehicle roll, catenary motion and longitudinal movement can obtain the control of expection, and 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, often occurs the phenomenon of cross-beam body two ends cracking, reinforces even if added auxiliary welded blank, still can not well deal with problems.
Summary of the invention
Technical matters to be solved by this invention is the cross-beam body that a kind of automobile 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.
Technical scheme of the present invention is that the cross-beam body of this kind of automobile torsion beam suspension comprises circular steel pipe, described steel pipe offers two openings along the length direction of steel pipe, and opening is smooth arc-shaped structure from two ends to the middle part of opening, the distance minimum of the line of centers of the middle part distance steel pipe of opening.
The distance of the line of centers of the middle part distance steel pipe of described opening is 2/3 of steel pipe radius.
Described opening adopts laser beam cutting to form.
The cross-beam body with this kind of automobile torsion beam suspension of said structure passes through 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.
Brief description of the drawings
Below in conjunction with accompanying drawing, invention is described further:
Fig. 1 is the structural representation of prior art.
Fig. 2 is the left view of structure shown in Fig. 1.
Fig. 3 is the structural representation of invention.
Fig. 4 is the birds-eye view figure of structure shown in Fig. 3.
In Fig. 1-4,1: opening.
Detailed description of the invention
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, often occurs the phenomenon of cross-beam body two ends cracking, reinforces even if added auxiliary welded blank, still can not well deal with problems.
Fig. 3-4 are structural representation of the present invention.This kind of automobile comprises circular steel pipe with the cross-beam body of torsion beam suspension, described steel pipe offers two openings 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 distance minimum of the line of centers of the middle part distance steel pipe of opening 1, the distance of the line of centers of the middle part distance steel pipe of opening 1 is 2/3 of steel pipe radius, and opening 1 adopts laser beam cutting to form.
This kind of automobile passes through the midway location opening at cross-beam body with the cross-beam body of torsion beam suspension, 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.
