To mobile electromagnetic force adhesive mechanism, the separating plate is equipped with the intercommunicating pore of the first oil pocket of connection and the second oil pocket, the connection
Hole is hinged with the door-plate unidirectionally opened towards the second oil pocket and is set equipped with the door-plate resetting-mechanism for closing door-plate, the door-plate
There are some main damp channels through door-plate, velocity sensor is equipped with the intercommunicating pore；When the velocity sensor detects
Oil from the first oil pocket flow to the second oil pocket when, the electromagnetic force adhesive mechanism stops driving first piston and second piston to shifting
It is dynamic；When the velocity sensor detects that oil flows to the first oil pocket from the second oil pocket, electromagnetic force adhesive mechanism driving the
One piston and second piston are to movement.The vibration isolating effect of the present invention can be improved.The specific shock absorbing process of the technical program is：
When it is vibrated and when causing damping spring to shrink, damping spring driving piston rod driving first piston is mobile and causes the first oil
Chamber reduces, and the oil that the first oil pocket is reduced in driving damping oil cylinder flows to the second oil pocket through intercommunicating pore from the first oil pocket, at this time door-plate
It is open so that oil stream does not produce damping action to oil through door-plate during intercommunicating pore and electromagnetic force adhesive mechanism is lost to first piston
With the fixation of second piston second piston is moved freely relative to first piston, it is achieved thereby that damping action
It is smaller that without causing, damping spring contraction is obstructed namely spring can be shunk in time and reduced spring contraction stroke and jolted, bullet
After spring retraction stroke under the action of door-plate resetting-mechanism, door-plate is stopped in intercommunicating pore again.Then spring elongation is multiple
Position and release energy, the result of elongation causes damping oil cylinder cylinder body and first piston to produce disengaging movement and the second oil pocket is reduced
And the first oil pocket becomes larger so that the oil in damping oil cylinder flows to the first oil pocket through intercommunicating pore from the second oil pocket, and electromagnetic force is inhaled at this time
Close mechanism and fix first piston and second piston and keep that relative position is constant and door-plate can not be open, allows oil to
From main damp channel by producing frictional damping energy dissipating in the whole spring contraction stroke, so as to reduce spring extended travel top

Referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, in use, the liquid such as filling oil in the first oil pocket 915 and the second oil pocket 916.Every
Shake seat 9 is supported on ground by support base 93.When being subject to road shocks and cause damping spring 92 to shrink, damping spring 92 drives
Piston bar 913 drives first piston 912 to move so that the first oil pocket 915 reduces, and the first oil pocket 915 reduces driving oil through even
Through hole 941 is from the first oil pocket 915 flows to the second oil pocket 916, the flow direction of oil is detected by velocity sensor 96, velocity sensor
96 control electromagnet 951 dead electricity, so that electromagnetic force adhesive mechanism 95 is lost to first piston 912 and the by control system
The fixation of two pistons 914（That is first piston 912 and second piston 914 can produce relative movement）, oil stream crosses intercommunicating pore
Door-plate 942 is pushed open so that oil stream is straight-through through intercommunicating pore 941 and enters the second oil pocket 916 when 941（I.e. door-plate 942 does not produce oil
Raw damping action）, it is achieved thereby that damping action is smaller, without causing, damping spring contraction is obstructed namely spring can be timely
Shrink and reduce spring contraction stroke and jolt, after spring contraction stroke under the action of door-plate resetting-mechanism（I.e. due to door
Keep down inclination and density of plate is more than oil）And rotate and close automatically, door-plate 942 stops in intercommunicating pore 941 again.Then subtract
The shake elongation of spring 92 is resetted and released energy, and the result of elongation causes damping oil cylinder cylinder body 911 and first piston 912 to produce separation
Movement is so that the second oil pocket 916 reduces and the first oil pocket 915 becomes larger so that oil flows to the through intercommunicating pore 941 from the second oil pocket 916
One oil pocket 915, the flow direction of oil are detected that velocity sensor 96 controls electromagnet by control system by velocity sensor 96
951, which obtain electric, electromagnet 951, produces magnetic force so that electromagnetic force adhesive mechanism 95 consolidates first piston 912 and second piston 914
It is fixed live and be pressed on oil, door-plate 942 can not be open, allow oil in whole spring contraction row during oily direction runner
Journey middle door-plate 942 produces frictional damping phenomenon and energy-absorbing, jolts so as to reduce spring extended travel.
The damping energy-absorbing shock absorbing process of door-plate is：Oil stream is rocked and will shaken through main damp channel, branch damp channel and damper rod
Energy is changed into thermal energy and consumes.When being not enough to promote the blind hole deform if vibration is smaller, only oil rocks at this time,
Damper rod is produced and rocked and energy-absorbing when oil rocks.
