Embodiment
The embodiment of the utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and it is not intended that to the utility model
Limitation.
Torsion beam crossbeam 100 below with reference to Fig. 1 to Fig. 3 descriptions according to the utility model embodiment.
As shown in Figure 1, cross-beam body 10 and flange 20 are included according to the torsion beam crossbeam 100 of the utility model embodiment,
The side wall of cross-beam body 10 opens wide and forms open ports 11, and flange 20 is located at the outside of open ports 11 and is connected to cross-beam body 10
On side wall.
According to the torsion beam crossbeam 100 of the utility model embodiment, by setting flange 20 on 10 side wall of cross-beam body,
While the structural strength of torsion beam crossbeam 100 is improved, to ensure the torsion stiffness of itself and then make it have preferably to subtract
Shock stability.
Some embodiments according to the present utility model, flange 20 are at least connected with a side in open ports 11 along upper.Also
It is to say, flange 20 can be attached only on the side of open ports 11, can also be connected on the both sides of open ports 11.Specifically
Ground, the extending direction of flange 20 are consistent with the extending direction of the side wall of cross-beam body 10.In other words, flange 20 is in cross-beam body
Extend on 10 side wall from central axis 300 (referring to Fig. 1) to both ends.As a result, the distribution of force of torsion beam crossbeam 100 is more
Rationally, and conveniently it is molded.
With reference to shown in Fig. 2, in view of the change of 100 stress of torsion beam crossbeam is very greatly, driving road-condition changes bigger, torsion beam crossbeam
The change of 100 stress is bigger, in order to adapt to the change of power in this driving conditions, by the way that flange 20 to be covered with to the torsion where it
On the edge of the open ports 11 of beam crossbeam 100, to achieve the purpose that to improve 100 integral strength of torsion beam crossbeam.
Some embodiments according to the present utility model, flange 20 have at least one section strengthening portion 21, section strengthening portion
21 cross-sectional area is more than the cross-sectional area of peripheral part.Specifically, can be according to force analysis and comprehensive various road conditions meter
The maximum either stress of the stress on torsion beam crossbeam 100 calculated changes maximum region and in stress maximum or stress
The maximum region of change sets section strengthening portion 21, to lift the intensity of relevant position.
As shown in figure 3, the number of section strengthening portion 21 is two, and two section strengthening portions 21 are relative in flange 20
Mandrel line 300 is symmetrical, and the cross-sectional area of flange 20 gradually increases from the central axis 300 of flange 20 to section strengthening portion 21
Greatly.That is, the cross-sectional area in the region between two section strengthening portions 21 is from section strengthening portion 21 to central axis
300 are gradually reduced.In this way, since the stress near the central axis 300 of torsion beam crossbeam 100 is smaller, ensureing that torsion beam is horizontal
While the intensity of beam 100 meets both ends stress, made to avoid 20 cross-sectional area of flange arranged at central axis 300 is excessive
Into local superfluous phenomenon.
Further, flange 20 prolongs from section strengthening portion 21 to one end adjoining with section strengthening portion 21 on flange 20
Constant cross-sectional area when stretching.Specifically, the end face strengthening portion 21 that neighbouring left end is set to left end extend when constant cross-sectional area, neighbour
The end face strengthening portion 21 that nearly right end is set to right end extend when constant cross-sectional area.
In certain embodiments, the constant thickness of flange 20, therefore the cross-sectional area size of flange 20 depends on flange 20
Width.
In figure 3, by marking off a region between two straight line of a, b, by another from being marked off between two straight lines of c, d
Region, the region divided are the section strengthening portions 21 on the torsion beam crossbeam 100 of a specific embodiment.
In the embodiment shown in fig. 3, positioned at the outer end of each section strengthening portion 21, (figure center line a left fields, line b are right
Side region) the width of flange 20 be fixed value, the width of section strengthening portion 21 is more than above-mentioned fixed value, section strengthening portion 21
Width is in from the outside to the core first increases and then decreases trend, and the flange 20 between two section strengthening portions 21 is (between line b and line c
Region) width be respectively less than the minimum widith of section strengthening portion 21.
Some embodiments according to the present utility model, the maximum cross-section area of flange 20 are the 1.2- of smallest cross-section area
1.4 again.In other words, the ratio at 20 cross-sectional area maximum of flange and cross-sectional area minimum is 1.2:1 to 1.4:1 scope
It is interior.
In the specific embodiment shown in Fig. 2, the distributing position of the maximum cross-section area of section strengthening portion 21 and adjacent with it
The distance between near one end of torsion beam crossbeam 100 accounts for the 1/5-1/4 of 100 entire length of torsion beam crossbeam, minimum cross-section
Product is at 300 place of central axis.
Specifically, the distributing position and torsion beam crossbeam of the maximum cross-section area for the section strengthening portion 21 that neighbouring left end is set
The distance of 100 left end is L1, and the entire length of torsion beam is L2, and wherein L1 is the 1/5-1/4 of L2；Correspondingly, neighbouring right end
The distributing position of the maximum cross-section area of the section strengthening portion 21 of setting and the distance of the right end of torsion beam crossbeam 100 are L3, are turned round
The entire length of power beam is L4, and wherein L3 is the 1/5-1/4 of L4.It is arranged so as to flange 20 and had both ensure that torsion beam crossbeam 100
Intensity reduces car body weight again.
Torsion beam crossbeam 100 and two torsion beam trailing arms are included according to the torsion beam assembly of the utility model embodiment
200.Two torsion beam trailing arms 200 are connected to the both ends of torsion beam crossbeam 100, and the flange 20 of torsion beam crossbeam 100 is with turning round
Power beam trailing arm 200 is adjacent and flange 20 at least formed at open ports 11 lower side along upper.
Thus, the torsion stiffness reduction vibration on the one hand by reducing torsion beam assembly finally improves ride comfort,
On the other hand the stability for vehicle being improved by improving the intensity of torsion beam assembly finally improves travel safety.
Include the torsion beam assembly of above-described embodiment according to the vehicle of another embodiment of the utility model.It is new according to this practicality
The vehicle of type, by improving the intensity of torsion beam crossbeam 100, reducing complete vehicle quality and torsion stiffness, to improve vehicle
Stability, passability, reduce fuel consumption, finally improves driving safety, ride comfort and reduces energy consumption.
