The slip of three telescopics and snap onto card slot mouth, the fixture block circular arc of fixture block and the purpose of design on draw-in groove inclined-plane are that fixture block can
Eaily enter into card slot mouth；It is lower under stiffness spring and pneumatic spring effect to push up when temporary extinction is impacted after shock
BOB(beginning of block) is moved upwards, but now triggering block cannot be moved up and down because fixture block is seized draw-in groove；Triggering transverse slat, triggering montant
Can be slid laterally along traversing guide groove with triggering block, after jacking block rises one by a small margin instantly, lower jacking block connects with triggering block
Contacting surface from triggering plane be changed into trigger ramp, during triggering block under the 3rd spring effect, triggering transverse slat to jettron pacify
Holding position direction is moved, and switch-mode regulation block is triggered by slide plate in moving process, enters the gases at high pressure in high pressure gas holder
To in pneumatic spring, increase the elasticity of pneumatic spring, the shock for preventing large impact next time from causing.The horizontal shifting of triggering block afterwards
Dynamic that fixture block can be caused to progressively disengage draw-in groove, after fixture block and draw-in groove depart from, draw-in groove, triggering montant and triggering block can be in second springs
The lower motion upwards of effect, and contacted with lower jacking block, lower jacking block is contacted with trigger ramp first to be opened so that triggering transverse slat back to gas
Close direction and recover home position, until lower jacking block downside and triggering plane contact, final plant closure gas switch.If road surface below
Relatively flat, the gases at high pressure after the time of one end in pneumatic spring can be released slowly into original gas outlet by the first gas outlet to be known
Other pressure, recovers normal coefficient of elasticity.The design function of slide plate in triggering transverse slat whole process all the time swinging up and down,
The design of slide plate ensure that and swing up and down optional position energy trigger switch regulating block.First expansion link and the first telescopic,
The design of two expansion links and the second telescopic and the 3rd expansion link and the 3rd telescopic is for increasing when spring is compressed
Lateral stability.The present invention only has jacking block rising instantly by a small margin in passing through after, gas can just enter in pneumatic spring
Purpose of design is to rise a bit of rear damping length increase to reduce high pressure gas holder gas into resistance during pneumatic spring
Power；First air inlet is that the purpose of design of unidirectional import is that the pressure of pneumatic spring will not be pressed by the first air inlet, only
Can be pressed by the first gas outlet.

Pressure have impact on the compressibility of gas, and then have impact on the coefficient of elasticity of pneumatic spring；Other pneumatic spring periphery also has tradition
Stiffness spring, when impact is in stiffness spring elasticity tolerance range, pneumatic spring air pressure inside stabilization, when impact is beyond rigidity
After in spring tolerance range, impact can be supported by lower jacking block, lower jacking block triggers trigger mechanism and causes that jettron is opened,
Jettron is opened can be introduced into pneumatic spring gases at high pressure by the first air inlet so that the coefficient of elasticity of pneumatic spring increases
Plus, alleviate excess impact next time.Specific embodiment is：Originally vehicle body is under own wt, the damping in damping
Mechanism and pneumatic spring keep certain relative position, and the length of now damping is most long, lower jacking block and triggering block
Contact surface is triggering plane, and second spring is compressed to a certain degree；When ground is raised smaller, the amplitude that lower jacking block swings up and down
It is smaller, and be triggering plane jacking block at present and the contact surface of triggering block is swung by a small margin up and down；Triggering block is perpendicular by vertical shift
Plate is slided and moved up and down in vertical shift guide groove, and moving downward for lower jacking block can be moved downward with triggering block, while to second
Spring is compressed；Instantly triggering block can follow lower jacking block to rise under second spring effect when jacking block rises, whole small size
In degree running, trigger mechanism is not triggered, and gas switch is in closure state all the time；When being caused rigidity by strong impact
After spring bears incessantly to impact, vehicle body can occur rigid impact with chassis, and when clashing into, damping is in most short status, touches
Hair montant is pressed onto card slot mouth and fixture block and coordinates by lower jacking block, and fixture block is snapped in by the 3rd expansion link and the slip of the 3rd telescopic
To in card slot mouth, the fixture block circular arc of fixture block and the purpose of design on draw-in groove inclined-plane are that fixture block can eaily enter into draw-in groove
In mouthful；When temporary extinction is impacted after shock, lower jacking block starts motion upwards under stiffness spring and pneumatic spring effect, but now
Triggering block cannot be moved up and down because fixture block is seized draw-in groove；Triggering transverse slat, triggering montant and triggering block can be along traversing
Guide groove slides laterally, and after jacking block rises one by a small margin instantly, lower jacking block is changed into tactile with the contact surface of triggering block from triggering plane
Hair inclined-plane, during triggering block under the 3rd spring effect, triggering transverse slat to jettron installation site direction move, be moved through
Switch-mode regulation block is triggered by slide plate in journey, the gases at high pressure in high pressure gas holder is entered into pneumatic spring, increased pneumatic
The elasticity of spring, the shock for preventing large impact next time from causing.The transverse shifting of triggering block can cause fixture block to progressively disengage afterwards
Draw-in groove, after fixture block and draw-in groove depart from, draw-in groove, triggering montant and triggering block can upwards be moved under second spring effect, and with
Lower jacking block contact, lower jacking block contact with trigger ramp so that trigger transverse slat back to gas switch direction recovery home position first,
Until lower jacking block downside and triggering plane contact, final plant closure gas switch.If road surface is relatively flat below, after the time of one end
Gases at high pressure in pneumatic spring can be released slowly into the pressure that original gas outlet recognizes by the first gas outlet, recover normal
Coefficient of elasticity.To be swung up and down all the time in triggering transverse slat whole process, the design of slide plate ensure that the design function of slide plate
Lower swing optional position can trigger switch regulating block.First expansion link and the first telescopic, the second expansion link and second are flexible
The design of set and the 3rd expansion link and the 3rd telescopic is for increasing lateral stability when spring is compressed.The present invention is logical
After crossing only jacking block rising instantly by a small margin, the purpose of design that gas can just enter in pneumatic spring be to rise one
The increase of damping length reduces high pressure gas holder gas into resistance during pneumatic spring after segment；First air inlet is unidirectional
