Have in view of that, while the utility model provides one kind and can rise vehicle control stability and ride comfort, can reduce
Influence of the lateral force to the damper service life increases damper arrangement space, so as to substantially increase the handling of vehicle and take
The McPherson suspension damper spring of comfort, to solve problems of the prior art.
A kind of McPherson suspension damper spring is provided according to the utility model, which is helical form, respectively encloses spiral
The line footpath of line and the central diameter of each circle helix are equal, and gradually increase along pitch of the hand of spiral from first end to second end
Greatly, the structure of variation rigidity is formed.
Preferably, the spring respectively enclosed from first end to second end along the hand of spiral helix central point connect to be formed it is curved
Bent multistage cable architecture.
Preferably, the middle section opposite sides of the multistage cable architecture of the bending is protruded towards external, forms spirogyrate
Structure.
Preferably, the multistage cable architecture of the bending is unsymmetric structure.
Preferably, across the vertical line of the central point of the outmost turns helix of the first end, and across the second end
The vertical line of the central point of outmost turns helix is intersecting vertically and into predetermined angle.
Preferably, which is 5-15 °.
Preferably, between each section of multi-section-line of the multistage cable architecture in same level.
McPherson suspension damper spring provided by the utility model is during Suspension movement with suspension compresses, bullet
Spring rigidity can gradually increase；Meanwhile spring can generate the power of compensation lateral force during the motion.Promoting vehicle operation stabilization
Property and while ride comfort, influence of the lateral force to the damper service life can be reduced, increase damper arrangement space, so as to carry significantly
The high handling and riding comfort of vehicle.
Description of the drawings
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution of the prior art
Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In all the appended drawings, it is similar
Element or part are generally identified by similar reference numeral.In attached drawing, each element or part might not be according to practical ratios
It draws.
Fig. 1 shows the front view of the McPherson suspension damper spring according to the utility model embodiment.
Fig. 2 shows the vertical views of the McPherson suspension damper spring according to the utility model embodiment.
In figure：First end 100, second end 200.
Specific embodiment
The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore example is only used as, and cannot this practicality be limited with this
Novel protection domain.
Fig. 1 shows the front view of the McPherson suspension damper spring according to the utility model embodiment.Fig. 2 shows
According to the vertical view of the McPherson suspension damper spring of the utility model embodiment.As shown in Figure 1 to Figure 2, the wheat is not
Inferior suspension damper is helical form with spring, and each line footpath for enclosing helix is equal, i.e., the helix is isometrical setting.It is in addition, each
The central diameter of circle helix is also equal to each other.The spring gradually increases along the hand of spiral from first end 100 to the pitch of second end 200
Greatly, the structure of variation rigidity is formed, and the rigidity of the spring is gradually reduced from first end 100 to second end 200.Due to bullet
Spring line footpath is constant, avoids production technology and quality stability caused by becoming line footpath stiffness variable spring in the prior art and asks
Topic so that the spring is easier to process and produces, and with better quality stability.
Adjacent successively three are schematically depicted from the first end of spring 100 to second end 200 with reference to figure 1, in Fig. 1
Pitch L1, L2 and L3, the length of L1, L2 and L3 are sequentially increased.The spring is along the hand of spiral from first end 100 to second end
The central point of 200 each circle helixes connects the multistage cable architecture to form bending.The middle section of the multistage cable architecture of the bending
Opposite sides is protruded towards external, forms spirogyrate structure.Since the central diameter that the spring respectively encloses helix is equal so that the spring
C-shaped configuration is looked like from whole.
Further, the multistage cable architecture of the bending is unsymmetric structure.Specifically, each section of the multistage cable architecture
Between multi-section-line in same level.With reference to figure 2, the outmost turns helix of the spring first end 100 is shown in FIG. 2
Central point A and the spring second end 200 outmost turns helix central point B.Across the outermost of the first end 100
The vertical line of the central point A of helix is enclosed, with the vertical line of the central point B of the outmost turns helix across the second end 200 each other
It intersects vertically and into predetermined angle.The predetermined angle is 5-15 °, such as 7 °, 9 ° or 13 °.Such structure design, with wheat not
Inferior suspension damper is tilted with spring to be set the set-up mode that opposed vertical direction is obliquely installed and matches, and can preferably provide side
To force compensating.
McPherson suspension damper spring in the embodiment is in use, it is tilted with damper opposed vertical direction
It is set on vehicle frame.Wherein, first end 100 is located at the top of second end 200.The spring is during Suspension movement with suspension
Compression, spring rate can gradually increase；Meanwhile spring can generate the power of compensation lateral force during the motion.Promoting vehicle
While control stability and ride comfort, influence of the lateral force to the damper service life can be reduced, increase damper arrangement space, from
And substantially increase the handling and riding comfort of vehicle.
