Kind, major part is analogous to the rubber of automobile tire, cord material, and the characteristics of its is maximum can be by regulation injection gas
Number change air pressure inside and spring heights, be a kind of adjustable springs so as to change the stiffness characteristics of spring.
Telescopic air spring is it can be seen from the equation of gas state, and keeping, the amount of internal air temperature, material is constant
In the case of, spring piston compresses internal gas since equilbrium position, and its characteristic showed is that rigidity constantly increases and tended to
It is non-linear to aggravate as piston deviates the increase of equilbrium position in infinitely great hardening characteristics.And gasbag-type air spring by
In factors such as material, designs, the characteristic of presentation varies, but is also rigidity hardening characteristics when generally compressing.
Mainly gasbag-type air spring widely used at present, main function is damping, for the stiffness characteristics of spring
It is required that not being very fine.Either stretch or compress compared to more typical metal spring, its rigidity is a definite value, " returning
It is centrosymmetric on origin in multiple power-deformation " coordinate system, and the restoring force of single air spring is on the origin of coordinates
It is asymmetrical.
In summary, it is necessary to propose a kind of air spring of Symmetric Composite at present so that the rigidity of this spring " is being returned
It is to realize restoring force approximately linear or strong nonlinearity on origin symmetry, and by design in multiple power-deformation " coordinate system
Characteristic, disclosure satisfy that the requirement of various engineering fields.Meanwhile, this spring can also be subject to appropriate control to realize mechanical property
The variable function of energy.

Minute surface is symmetrically placed, and overall two ends are fixing ends, and the docking point of two springs is hard point (so-called " fixing end ", " load
Point " is the two ends of common spring), realize elastic connection between the two.
In order to realize mechanical property changeable, by controlling air spring air pressure inside, cylinder (air chamber) volume to reach
To purpose.
The technical solution of the utility model:
A kind of air spring of rigidity controllable Symmetric Composite, including piston 1, piston rod 2, hard point 3, cylinder 4, cylinder wall
5th, air spring I 6 and air spring II 7, two identical air springs are symmetrically placed, connected by piston rod 2, piston rod

Situation about moving right is completely opposite;Deforming in less scope, overall rigidity is similar to a definite value.
Described air spring I 6 and air spring II 7 is all telescopic air spring or is all gasbag-type air spring.
A kind of control system of the air spring of Symmetric Composite, includes air spring, the additional chamber of above-mentioned Symmetric Composite
8th, liquid 9 and capillary 10;
Additional chamber 8 is symmetrical arranged on the basis of the air spring of Symmetric Composite, additional chamber 8 is built with liquids and gases two
Certain media;The cylinder 4 of air spring I 6 and air spring II 7 is communicated with volume identical additional chamber 8 respectively, two additional chambers
8 are connected by capillary 10, and adjust control by control pressurer system, i.e., gas is communicated in the controls;Capillary 10
Not only gas charge and discharge had been controlled but also had prevented air spring the amount of gas is unequal in cylinder 4 during exercise;Liquid also leads in two additional chambers 8
Cross capillary 10 to communicate, the control principle of liquid height is identical with air pressure control principle.
The beneficial effects of the utility model:
1. the volume size of auxiliary chamber directly affects overall mechanical characteristic, keeping holding in the case that other specification is constant
Product is bigger, and " restoring force-deformation " curve is more intended to straight line, and rigidity is more intended to certain value, but mutually sympathizes with maximum distortion
Condition lower spring total bearing capacity is reduced, and vice versa;
2. insufflation gas is more in air chamber, its initial air pressure inside is bigger, and spring integral rigidity is bigger, non-linear to get over
By force, total bearing capacity increases when maximum distortion is identical, and vice versa;
3. the liquid being filled with air chamber is more, liquid level is higher, then the internal capacity of auxiliary chamber is smaller.
