S1: it needs to dig out the groove to match with substrate size on passing road, and substrate is embedded in passing road；
S2: when vehicle travels in passing road and vehicle passes through substrate with speed v, vehicle and it is slideably positioned in substrate
Interior bearing plate contact, and pressure is applied to bearing plate, bearing plate is pushed to sink；
S3: when speed v is higher by default speed limit, the kinetic energy of vehicle is larger and the time of contact of wheel and bearing plate compared with
Short, the instantaneous velocity of bearing plate decline is larger and drives the lock pillar that is connected with bearing plate bottom surface to glide at a high speed, lock pillar to
When lower slider, so that the piston for being set to lock pillar bottom surface slides in the air cavity in the lower sleeve being socketed on outside lock pillar, it is living
It fills in quick glide downwards and the air pressure in air cavity is had compared with hyperbar, the gas in air cavity is passed through with high flow velocities and air cavity
The stomata of connection, ventilation pipe simultaneously flow to fluid induction valve body；The air for flowing to fluid induction valve body has high flow velocities, part
Air is entered in chamber b by air hole, and another part air is expelled to outer by the inlet and outlet pipeline being connected with chamber a
Portion, the positioning spool being slideably positioned in chamber b are moved through mandrel to lock pillar direction by the thrust of high flow rate air and lead
The barrier spool for drawing arrangement concentric with it moves synchronously, and while barrier spool is moved towards lock pillar direction, barrier spool is gradually
Diminution inlet and outlet pipeline and chamber a interface area so that positioning the bigger air thrust of spool activity；High flow rate air pushes away
Dynamic positioning spool overcomes the resistance for the resistance spring being set in chamber b into lock pillar direction motion process, and mandrel is to lock pillar side
To when stretching out, mandrel pushes locking sliding block to slide in the horizontal direction in upper bush, and upper bush is installed on lower sleeve upper end, lock
The end of limited slip block towards lock pillar is provided with helical teeth b, and spaced apart helical teeth a, mandrel along the vertical direction are provided on lock pillar and is pushed away
Helical teeth b on dynamic lock pillar sliding block is meshed with the helical teeth a on lock pillar, continues traveling downwardly to limit lock pillar, block bearing plate after
Continuous downlink, realizes the blocking purpose of bearing plate；
S4: when speed v is lower than default speed limit, the kinetic energy of vehicle is smaller and the time of contact of vehicle and bearing plate compared with
Long, the initial velocity of bearing plate decline is smaller and drives the lock pillar being connected with bearing plate bottom surface to glide compared with low velocity, living
The air pressure flowed out out of air cavity when filling in downlink is smaller, and generates lesser thrust to positioning spool, and moving air is to positioning
The resistance that spool generates is not enough to overcome the elastic force of resistance spring, so that inlet and outlet pipeline remains unimpeded with chamber a,
And locking sliding block is in always can push lock pillar glide downwards to maximum position with lock pillar disengaged position, bearing plate；
S5: when vehicle is crossed from bearing plate or does not apply pressure to bearing plate, the jacking that is installed in lower sleeve
Spring gives piston upward active force, and lock pillar, bearing plate is pushed to move upwards, so that pressure-bearing sheet reset；Piston is transported upwards
During dynamic, the space in air cavity increases, and at the same time, external gas is from inlet and outlet pipeline, chamber a, ventilation pipe, stomata
It flows into air cavity, resistance spring pushes positioning spool towards the movement of lock pillar direction is deviateed, and is installed on the reset spring of upper bush
Locking sliding block is pushed to deviate the movement of lock pillar direction.
The numerical value of default speed limit can carry out adaptability adjusting according to different sections of highway, it is preferable that above-mentioned default speed limit is 10-
35KM/H；The numerical value of default speed limit can be adjusted according to the coefficient of elasticity of resistance spring 460h, and the numerical value of default speed limit may be used also
It is adjusted according to the air velocity that air valve a, air valve b are controlled；The rebound reset speed of bearing plate can be according to jacking spring 430b
Coefficient of elasticity be adjusted.
