Dress.When by road shocks the most vibrated and when causing damping spring to shrink, damping spring drives piston rod to drive first to live
Plug is mobile and the first oil pocket is reduced, and the first oil pocket reduces and drives oil in damping oil cylinder to flow to the through window from the first oil pocket
Two oil pockets, now door-plate is open so that when oil flows through window, door-plate does not produces damping action to oil and electromagnetic force adhesive mechanism is lost
Go the fixation of first piston and the second piston makes the second piston can move freely relative to first piston, thus real
Show that damping action is less is obstructed namely spring can shrink in time and reduce spring contraction without causing damping spring to shrink
Stroke jolts, spring contraction stroke terminate after under the effect of door-plate resetting-mechanism, door-plate stops again in window.Then bullet
Spring elongation resets and releases energy, and the result of elongation causes damping oil cylinder cylinder body and first piston generation isolated movement to make second
Oil pocket reduces and the first oil pocket becomes big so that the oil in damping oil cylinder flows to the first oil pocket through window from the second oil pocket, now electricity
First piston and the second piston are fixed the relative invariant position of holding by magnetic attraction mechanism and door-plate can not be open, make
Oil can in whole spring contraction stroke from main damp channel by and produce frictional damping energy dissipating, thus reduce spring elongation
Stroke jolts.Isolating affection is good.

The state of position).When making rotating nut convenient and strength-saving.
When nuts and bolt is screwed together, pressing the second driving post 8222, second drives post 8222 to drive post fixed
Position latch 8224 departs from the first driving post 8221, drive post depart from spring 825 drive the first driving post 8221 to eject and lose right
Come directly towards the driving effect of 821 and make to drive post fastening screw 8224 can not be inserted in the first driving post 8221.Now stop
Can relatively rotate between pendulum section 812 and main paragraph 811, vibrated and cause blind rivet to have the trend of disengaging with connecting screwed hole
Time, only the rotation of pendulum section 812 and main paragraph 811 can cause the screw thread of the two to stagger, thus stops the generation of abjection.
See Fig. 7, in damping oil cylinder cylinder body 911, be additionally provided with the second piston 914 and separating plate 94.Separating plate 94 and damping oil
Cylinder cylinder body 911 is fixed together.The first oil pocket 915 is formed between damping oil cylinder cylinder body 911 and first piston 912.Separating plate 94
With second form the second oil pocket 916 between piston 914.The internal diameter of the first oil pocket 915 is more than the internal diameter of the second oil pocket 916.First
Oil pocket 915 and the second oil pocket 916 are distributed along the vertical direction.Separating plate 94 is provided with window 941.Window 941 connects the first oil pocket 915
With the second oil pocket 916.
Electromagnetic force adhesive mechanism 95 it is provided with between first piston 912 and the second piston 914.Electromagnetic force adhesive mechanism 95 includes
Electric magnet 951 and ferrimagnet sheet 952.Electric magnet 951 is arranged on first piston 912.Ferrimagnet sheet 952 is arranged at
On second piston 914.
Window 941 is provided with door-plate 942.
Seeing Fig. 8, door-plate 942 is hinged in window 941 by door-hinge 9421.Separating plate 94 is provided with door-plate resetting-mechanism.
Door-plate resetting-mechanism is the torsion spring being arranged in the rotating shaft of door-plate.Door-plate 942 is only capable of towards the second unidirectional unlatching of oil pocket 916.Window
It is provided with velocity sensor 96 in mouth 941.Door-plate 942 is provided with some main damp channels 9422 running through door-plate.Main damp channel
Damper rod 9423 it is equipped with in 9422.Damper rod 9423 mating spherical surfaces is connected in main damp channel 9422.Damper rod 9423 sets
There is a damp channel 9424.Door-plate 942 is all stretched out at the two ends of damper rod 9423.Two end faces of damper rod 9423 are all sphere.
Damper rod 9423 is cylindrical.
See Fig. 9, two end faces of damper rod 9423 are designed with some increasing resistance grooves 9425 circumferentially distributed along damper rod.
See Fig. 3, Fig. 7, Fig. 8 and Fig. 9, during use, in the first oil pocket 915 and the second oil pocket 916, fill the liquid such as oil.?
Spike 9 is supported on ground 1 by supporting seat 93.When being caused damping spring 92 to shrink by road shocks, damping spring 92
Driving piston rod 913 to drive first piston 912 to move and first oil pocket the first oil pocket 915 is reduced, the first oil pocket 915 reduces
Drive oil to flow to the second oil pocket 916 through window 941 from the first oil pocket 915, this flow direction of oil is detected by velocity sensor 96, speed
Degree sensor 96 controls electric magnet 951 dead electricity by control system so that electromagnetic force adhesive mechanism 95 loses and lives to first
Plug 912 and the fixation (i.e. first piston 912 and the second piston 914 can produce relative movement) of the second piston 914, oil stream
When crossing window 941, door-plate 942 is pushed open so that oil flows through that window 941 is straight-through and to enter the second oil pocket 916(i.e. door-plate 942 the most right
Oil produces damping action), it is obstructed namely spring can it is achieved thereby that damping action is less without causing damping spring to shrink
Shrink in time and reduce spring contraction stroke and jolt, spring contraction stroke terminate after under the effect of door-plate resetting-mechanism 97 (i.e.
Keep down due to door-plate and density be more than oil) and automatically rotate and close, door-plate 942 stops again in window 941.So
The elongation of rear damping spring 92 resets and releases energy, and the result of elongation causes damping oil cylinder cylinder body 911 and first piston 912 to produce
Isolated movement makes that the second oil pocket 916 reduces and the first oil pocket 915 becomes big so that oil flows to from the second oil pocket 916 through window 941
First oil pocket 915, this flow direction of oil are detected by velocity sensor 96, and velocity sensor 96 controls electric magnet by control system
951 electric, electric magnet 951 produces magnetic force so that electromagnetic force adhesive mechanism 95 is by solid to first piston 912 and the second piston 914
Determining to live and be pressed on oil, during oil direction runner, door-plate 942 can not be open, allow oil at whole spring contraction row
In journey door-plate 942 produce frictional damping phenomenon and energy-absorbing thus reduce spring extended travel and jolt.
The damping energy-absorbing shock absorbing process of door-plate is: oil flows through main damp channel, a damp channel and damper rod and rocks and will shake
Energy is changed into heat energy and consumes.If vibrate less and when being not enough to promote blind hole to deform, now only the rocking of oil,
When oil rocks, damper rod produces and rocks and energy-absorbing.
