Hydraulic tubing operates for driving tail structure, comprise Hydraulic Pump 22, for while break-make two main wing cylinders main wing pipeline, for while the aileron pipeline of break-make two aileron cylinders and the rotation auxiliary line for each rotation auxiliary cylinders of independent break-make, Hydraulic Pump is responsible for hydraulic oil to extract out from petrol storage tank, and the hydraulic oil of extraction needs first to be filtered by fil 21.Main wing pipeline, aileron pipeline and rotation auxiliary line install in parallel.Main wing pipeline comprises main wing three position four-way electromagnetic valve 17, is provided with a check valve 24 before main wing three position four-way electromagnetic valve, arranges an energy storage 23 between check valve and main wing three position four-way electromagnetic valve.Aileron pipeline comprises aileron three position four-way electromagnetic valve 18, is provided with a check valve before aileron three position four-way electromagnetic valve, arranges an energy storage between check valve and aileron three position four-way electromagnetic valve.Rotate auxiliary line and comprise two branch roads, branch road is respectively equipped with a check valve and rotates auxiliary three position four-way electromagnetic valve 19, in two auxiliary three position four-way electromagnetic valves of rotation, one is left-hand rotation dynamic auxiliary three position four-way electromagnetic valve 19a, another is right-hand rotation dynamic auxiliary three position four-way electromagnetic valve 19b, and the rotation of check valve and correspondence is assisted between three position four-way electromagnetic valve and arranged an energy storage.In main wing pipeline, two main wing cylinders adopt parallel way, act on two main wing cylinders simultaneously, make two main wing cylinders can complete lifting simultaneously by the oil circuit of main wing three position four-way electromagnetic valve.In aileron pipeline, two aileron cylinders also adopt parallel way, act on two aileron cylinders by the oil circuit of aileron three position four-way electromagnetic valve simultaneously, and two aileron cylinders can be rotated by complete operation aileron simultaneously.And in rotation auxiliary line, control respectively to rotate auxiliary cylinders by branch road, left-hand rotation dynamic auxiliary three position four-way electromagnetic valve is for controlling the tail structure in left side, right left-hand rotation dynamic auxiliary three position four-way electromagnetic valve, for controlling the tail structure on right side, makes the rotational angle of two tail structures can not be identical.In addition, pressure release branch road is also set, comprises a blowdown valve 20, before blowdown valve is positioned at each check valve, when pipeline inner pressure is excessive, can by oil pressure relief removal in pipeline.
Main wing three position four-way electromagnetic valve in hydraulic tubing, aileron three position four-way electromagnetic valve are connected by controller with the auxiliary three position four-way electromagnetic valve of rotation, and controller can be the ECU of automobile, also can be the control units arranged separately.This outer controller is also for collecting the speed information of automobile, brake signal and lateral acceleration signal, and controller is electrically connected a button 25, for the opening and closing of Non-follow control aileron.
In actual moving process, when the speed of a motor vehicle is lower, as shown in Figure 5, tail structure is in initial condition, and main wing is arranged in hoist trunk, and main wing upper surface front end flushes with hoist trunk edge or substantially flushes, main wing does not rise, and simultaneously the front end of aileron and main wing upper surface fit.When the speed of a motor vehicle is promoted to more than 90KM/H, as shown in Figure 6, the left position connecting system of main wing three position four-way electromagnetic valve, oil pressure promotes the piston of two main wing cylinders, main wing cylinder piston rod is ejected, is together upwards released by main wing together with aileron and end plate, there is free air-flow warp the below of main wing and aileron, upper and lower surface produces difference of pressure, and then produces downforce to the tailstock; And when the speed of a motor vehicle drops to lower than 90KM/H, the right position connecting system of main wing three position four-way electromagnetic valve, makes main wing and aileron drop in hoist trunk.
When the further rising of the speed of a motor vehicle, as shown in Figure 7, two are rotated the equal connecting system in left position of assisting three position four-way electromagnetic valve, now oil pressure promotes the piston that two are rotated auxiliary cylinders, main wing is together rotated forward together with aileron and end plate, main wing forward pivot angle is proportionate with rotation auxiliary cylinders piston stroke, and pivot angle is 30 degree to the maximum forward.
When braking, two are rotated the equal connecting system in left position of assisting three position four-way electromagnetic valve, and rotate auxiliary cylinders piston stroke simultaneously and reach maximum, therefore rotational angle is maximum forward for main wing and aileron, to obtain maximum wind area, thus provides maximum windage.
When automobile high-speed is turned, centnifugal force produces larger lateral acceleration, as automobile turn left time, vehicle body is subject to centrifugal action to the right, because Location of Mass Center of Automobiles is higher than automobile roll center, the trend that the bank moment produced makes automobile have to incline to the right, automobile left side wheel is to the pressure drop on ground, and right side wheels is to the pressure increase on ground.Now, two are rotated the equal connecting system in left position of assisting three position four-way electromagnetic valve, but assist three position four-way electromagnetic valve for the rotation of the left-hand rotation dynamic auxiliary cylinder controlling left side tail structure, its in-service time is greater than right-hand rotation dynamic auxiliary three position four-way electromagnetic valve, the lift controlling left side tail structure transfer dynamic auxiliary cylinder piston is made to be greater than the lift controlling right side tail structure transfer dynamic auxiliary cylinder piston, finally make rotational angle difference 10 to 30 degree of main wing in two tail structures, corner extent increases along with the increase of lateral acceleration.Like this, be positioned at the tail structure in left side, it compares the tail structure on right side, produce larger downforce, thus formation aligning torque offsets the bank moment produced by centnifugal force at least partially, thus reduce body roll, improve the adhesive ability of left side wheel, reduce the load of right side wheels.Meanwhile, due to the outer corner difference of both sides tail structure, make the windage of left side tail structure be greater than opposite side, the windage different by both sides produces the auxiliary torque identical with Vehicular turn direction, thus provides extra steering torque.
When automobile gives it the gun on straight way, as shown in Figure 8, driver is by manual control button, and by left for aileron three position four-way electromagnetic valve position access hydraulic tubing, thus aileron is upwards rotated, the downforce that aileron produces and windage reduce.Simultaneously due to after aileron opens, valve is opened due to keep-spring effect, the high pressure draft produced above main wing flows out from the air extractor duct of main wing lower surface through bypass air flue, thus it is poor to reduce main wing two-way pressure, this makes main wing air resistance and downforce reduce, vehicle travel resistance reduces, and is convenient to automobile and accelerates faster, improves 10 to 15KM/H when very fast relative aileron can be made when long straight way gives it the gun not rise.In this case, if driver steps on brake pedal, the right position of aileron three position four-way electromagnetic valve and two left positions of rotating auxiliary three position four-way electromagnetic valve are accessed in hydraulic tubing, tail structure overall while rotating forward also by aileron return, in the process of aileron return, aileron is by push pedal by valve closing, thus is closed by bypass air flue.
