Specific embodiment
The embodiments of the present invention is described further with reference to the accompanying drawing.
The specific embodiment 1 of the vehicle of the utility model, as shown in Figure 1 to Figure 3, vehicle include vehicle frame, suspension with
And wheel, vehicle wheel rotation are mounted in vehicle bridge, suspension is connected between vehicle bridge and car body for carrying out elastic branch to car body
Support, can not only filter the tiny of road surface and jolt, additionally it is possible to improve the overall stability and balance of vehicle under steam.This reality
Applying the suspension in example includes air spring and damper 3, supports vehicle frame jointly by air spring and damper 3, so that
Vehicle meets corresponding rigidity requirement.The air spring includes air bag 1 and auxiliary tank 2, is set between air bag 1 and auxiliary tank 2
There is communicating passage 20, and is equipped with headstock gear at 20 position of communicating passage on auxiliary tank 2.
Headstock gear in the present embodiment includes the valve that two panels is hinged on auxiliary tank 2, is also being connected on auxiliary tank
Closed state is turned in valve along 21 equipped with the angular gear that block is bonded in valve-closing with the shop front of valve at circulation passage
When, the opposite edge pairing sealing of each valve, each valve are with corresponding angular gear along 21 gluing, sealings, two panels valve-closing
The V-structure of sealing is constituted afterwards, and two panels valve is that the magnetic sheet a10 and magnetic sheet b11 for swinging division, magnetic sheet a10 and magnetic sheet b11 are different
Property magnet, according to the principle that there is a natural attraction between the sexes, two magnetic sheets under conditions of not by external force, automatic absorbing together, so as to form
The sealing of air bag and the separation of air bag and auxiliary tank.Herein, magnetic sheet a and magnetic sheet b is integrally that magnetic material forms magnet
Valve can also be that a valve is magnet valve, another is the valve of ferromagnetic material (such as iron, cobalt, nickel).
Filled with high pressure gas in air bag, high pressure herein can be understood as the normal pressure for stablizing support vehicle frame, gas
The top of capsule is provided with air bag cover plate 12, is fixed on vehicle frame by air bag cover plate 12, and connection gas is provided on air bag cover plate
The air inlet and air outlet of intracapsular chamber are filled with gas into the inner cavity of air bag by air inlet using air pump, to improve in air bag
The pressure of gas, and then increase the rigidity of air spring, air pump forms making-up air device.Correspondingly, gas outlet can be according to reality
Situation discharges the high pressure gas of air bag inner cavity to reduce pressure therein.When magnetic sheet a and magnetic sheet b are washed open by gas in order to prevent
Swing angle is excessive, prevents magnetic sheet a and magnetic sheet b from being automatically closed by magnetic attraction, is additionally provided at communicating passage for limiting
The position limiting structure 22 of swing angle when valve is rushed to open, the wall surface of communicating passage forms position limiting structure 22 herein.
The lower part of auxiliary tank is provided with the bolt hole for releasable connection air chamber support 4, the upper and lower ends of air chamber support 4
It is connect respectively with auxiliary tank and vehicle bridge, auxiliary tank is rigid cavity in the present embodiment, and is additionally provided on auxiliary tank
Explosion relief guarantees that gas and ambient atmosphere in auxiliary tank keep identical pressure by explosion relief slow release gas.When
Vehicle supports car body to keep stablizing in flat road surface normally travel, through the high pressure gas in air bag, at this time magnetic sheet a and magnetic sheet
B is attached together, and the gas pressure in air bag is not enough to wash open magnetic sheet a and magnetic sheet b.When vehicle driving arrives deceleration strip etc.
When bump, due to wheel and vehicle bridge fast upward motion, air bag is become smaller by fierce compression volume, and gas pressure intensity quickly increases
Greatly.When the pressure value of gas reaches setting value, the component for the gas pressure that magnetic sheet a and magnetic sheet b are subject to is greater than between two magnetic sheets
Attraction, the gas that magnetic sheet a and magnetic sheet b are fiercely compressed washes open, and communicating passage is opened, the cavity of air bag and auxiliary tank
Cavity connection, portion gas enter in auxiliary tank；Gas volume becomes larger, and pressure moment becomes smaller, due to magnetic sheet a and magnetic sheet b it
Between magnetic attracting force be attached together at once again, communicating passage is closed, and the gas flow in air bag is reduced, the rigidity of air spring
It reduces, the compression deformation ability of suspension improves, it is ensured that vehicle can be smoothly through bumps such as deceleration strips.
After vehicle passes through deceleration strip, the gas that air pump blasts respective volume into air bag carries out pressure supplement, it is ensured that vehicle
In flat road surface normally travel, the suspension of vehicle is restored to positive constant stiffness, prevents due to suspension Stiffness
Vehicle is caused to roll when excessively curved seriously.The inner and outer air pressure that auxiliary tank can be balanced by explosion relief, avoids because of auxiliary tank
It is completely enclosed and in its chamber cylinder accumulation after causing gas to be passed through, otherwise, needed if magnetic sheet a to be washed open and magnetic sheet b bigger
Pressure, that is, require the compression deformation of air spring bigger, be not able to satisfy practical application.Magnetic sheet a and magnetic in the present embodiment
Piece b forms headstock gear, which is pure mechanic structure, eliminates because the environmental changes such as temperature, humidity, vibration lead to electricity
The hidden danger of subcomponent failure, in particular, air spring also will receive level side when passing through the bumps such as deceleration strip for vehicle
To impact force, the headstock gear can be completely suitable for air spring occur front and back dislocation deformation, avoid and thus cause
The problem of component damage and job insecurity, improves the functional reliability of vehicle.
The specific embodiment 2 of the vehicle of the utility model is that headstock gear can wrap with the difference of specific embodiment 1
Include the valve that three pieces are hinged on auxiliary tank, each valve is triangular structure or 120 ° of covering of the fan structures, any after valve-closing
Sealing, and each valve and phase are formed between two bevel edges or two radiuses and the bevel edge or radius of two adjacent valves of valve
The sealing gear answered is along fitting to block communicating passage.Alternatively, valve can also have four etc..
The specific embodiment 3 of the vehicle of the utility model, is with the difference of specific embodiment 1, keeps off on valve with sealing
It is magnet along the position matched, laterostigmatal magnet, which generates magnetic attraction along upper anisotropic magnet or ferromagnetic material with sealing gear, to be made
Valve-closing makes each valve by the magnet of marginal position alternatively, the marginal position far from hinged side of each valve is magnet
Closed state can be turned under magnetic attraction effect, then alternatively, each valve sheet as ferromagnetic material, and seals gear along upper and gas
The position that door matches is magnet, and actively generating magnetic attraction to each valve along upper magnet by sealing gear makes valve-closing.
The specific embodiment of the air spring of the utility model, it is hollow with the specific embodiment of the vehicle of the utility model
Identical in each specific embodiment of gas spring, details are not described herein.
