one side fixedly connected with face gear 16 that cylinder 6 is close to side fence 2, face gear 16 can mesh with arc pinion rack 15, generator 17 of fixedly connected with on the bottom plate 1, generator 17 rotor and 5 fixed connection of circle axle, fan 18 of fixedly connected with on the bottom plate 1, fan 18 and generator 17 electric connection, generator 17 electricity generation can be to the power supply of fan 18, the fixed tuber pipe 19 that is provided with of output of fan 18, the directional direction of coming the car of tuber pipe 19 slope, make the gas that tuber pipe 19 blew off produce bigger resistance to the vehicle.
The cross-sectional inner diameter of the first cylinder 9 is smaller than that of the second cylinder 12, and the first cylinder 9 is communicated with the second cylinder 12 through the communicating pipe 8, so that when liquid is filled in the communicating pipe, the pressures of all parts are equal, the pressure borne by the second piston 13 is larger than the pressure of the elastic membrane 4 on the first piston 10, and the second push rod 14 and the arc toothed plate 15 can be driven to move when the elastic membrane 4 moves.
The distance between fan 18 and the generator 17 in the direction of perpendicular to circular shaft 5 is about 1.2 meters, the overhang size in the front of car on the existing market is mostly 0.9 meters, when the front wheel of firm vehicle contacts with cylinder 6, fan 18 and tuber pipe 19 are located the dead ahead of vehicle roughly, guarantee that the gas that tuber pipe 19 bloated can be effectual produces the effect of slowing down to the vehicle, the gas that tuber pipe 19 bloated also makes the air current in vehicle the place ahead accelerate simultaneously, make the elastic membrane 4 in vehicle the place ahead produce certain deformation volume, when guaranteeing that the vehicle passes through elastic membrane 4, elastic membrane 4 deformation volume is enough to make arc pinion rack 15 and terminal surface gear 16 break away from the contact.
In the use process of the device, a plurality of devices are alternately arranged, as shown in fig. 5, the rollers 6 and the fan 18 are alternately arranged, and the rollers 6 are all at the same height. When the vehicle is driving on a road provided with the device, the tires of the vehicle are in contact with the rollers 6.
In the device, when a vehicle is not driven on a road provided with the device, the air pressure on two sides of the elastic membrane 4 is equal, under the elastic action of the elastic membrane 4, the elastic membrane 4 is in a straight state, at the moment, the first piston 10 is positioned on one side, far away from the side rail 2, of the first cylinder 9, so that more oil in the first cylinder 9 is extruded into the second cylinder 12, at the moment, the second piston 13 is positioned at one end, close to the side rail 2, of the second cylinder 12, the arc-shaped toothed plate 15 on the second push rod 14 fixedly connected with the second piston 13 is meshed with the face gear 16, as the arc-shaped toothed plate 15 cannot rotate around the circular shaft 5, the roller 6 cannot rotate, when the vehicle is driven on the laid roller 6 at a slow speed, the rapid flow of surrounding air cannot be disturbed due to the slow speed, the deformation amount of the elastic membrane 4 is less, at the moment, the roller 6 cannot rotate, when a tire of the vehicle contacts and rotates with the roller 6, the roller 6 generates reaction force to the wheels to provide forward power for the vehicle, and therefore the vehicle can be guaranteed to move forwards stably.
When the speed of vehicle is very fast, the vehicle can drive the velocity of air flow on every side and accelerate rapidly, shows that the velocity of air flow that elastic membrane 4 is close to vehicle one side is greater than the opposite side far away promptly, can obtain according to aerodynamic knowledge: the air pressure of one side, close to the vehicle, of the elastic membrane 4 is far smaller than that of the other side, the elastic membrane 4 deforms under the action of the air pressure to drive the first push rod 11 to move, at the moment, the first piston 10 moves along with the elastic membrane, negative pressure is generated in the first cylinder 9, oil in the second cylinder 12 is pumped into the second cylinder 12 through the communicating pipe 8, and the second piston 13 in the second cylinder 12 obviously moves towards the direction far away from the vehicle; the faster the vehicle moves, the greater the speed difference of the air flow at the two sides of the elastic membrane 4, that is, the greater the pressure drop of the air at the two sides, the greater the deformation of the elastic membrane 4, that is, the greater the movement amount of the first push rod 11 and the second push rod, when the vehicle is overspeed, the violent deformation of the elastic membrane 4 causes the arc toothed plate 15 to be disengaged from the face gear 16, and at this time, the roller 6 can rotate;
when the vehicle moves to the state that the tire is in contact with the roller 6, the wheel rotates at a high speed under the action of the internal engine to further drive the roller 6 to rotate, and at the moment, the roller 6 cannot generate a strong reaction force on the wheel, namely, the high-speed rotation of the wheel cannot generate continuous forward power on the vehicle, so that the speed of the vehicle cannot be continuously increased, the vehicle can only slide forwards under the inertia effect of the wheel, and in the sliding process, the vehicle can slowly slow down under the action of various resistances;
because the round shaft 5 is fixedly connected with the generator 17 in a rotating manner, when the round shaft 5 rotates along with the roller 6, the generator 17 can generate electricity to drive the fan 18 to work, the fan 18 generates high-strength wind power in work and blows to the front end of a vehicle, more obvious air resistance is generated for the vehicle, and the vehicle deceleration effect is more obvious. To sum up: on the road provided with the device, the wheels of the overspeed-running automobile can not provide power for enabling the automobile to continuously move at high speed, and the automobile can bear larger air resistance, so that the speed of the automobile can be stably reduced until the speed is lower than a limited speed, the arc-shaped toothed plate 15 can not be contacted with the end face gear 16 when the air flows are disturbed by the automobile, and finally the overspeed of the automobile can be prevented.
Therefore, the road section provided with the device is a straight line section, and the air pipes 19 of the device are uniformly arranged at the front end of the vehicle, so that the wind power of the air pipes 19 to all parts of the front end of the vehicle is equal, and the vehicle can be stably decelerated.
Although the terms of the bottom plate 1, the side rail 2, the side hole 3, the elastic membrane 4, the circular shaft 5, the roller 6, the fixing block 7, the communicating tube 8, the first cylinder 9, the first piston, 10, the first push rod 11, the second cylinder 12, the second piston 13, the second push rod 14, the arc-shaped toothed plate 15, the face gear 16, the generator 17, the fan 18, the air duct 19, etc. are used more herein, the possibility of using other terms is not excluded.
