Description

Brake System of Road Surface Adsorption

The present invention relates to a system of a braking system of a traffic engine driving on a road surface, and more particularly, when a braking system is suddenly braked to shorten a braking distance in an emergency and force majeure situation while driving. It is related to the braking system of a traffic engine that has additional braking force due to the adsorption load acting in conjunction with the brake, and shortens the braking distance and the braking stability. There is this.

As a braking device for a traffic engine driving on a road surface, a tire and a road surface due to the weight of a vehicle generated when the speed of the outer peripheral surface of a tire rotating in contact with the road surface is reduced due to the thermal conversion action caused by friction between the wheel and the lining. The braking force is generated by the frictional force of the brake and the anti-lock brake system (ABS) braking system installed on the aircraft and automobile is used to adjust the slip ratio of the road surface and tire to the best state in order to shorten the braking distance and improve the turnability. In addition, it maintains the maximum ground resistance and contributes greatly to shortening the braking distance and granting turning power.However, the braking distance becomes longer in the case of force majeure, such as when driving at high speed or when the road surface is slippery due to rain or ice. Due to the accident can not only cause an accident, the braking force is obtained by using the air resistance as an auxiliary braking device, The method of spreading the furnace plate is useful only for ultra high speed driving, and the method of obtaining braking force by spraying high pressure fluid in the direction of driving reverse of a traffic engine has a lot of energy requirements and practical limitations due to the blowing sound. Many of the braking devices that are installed and act on rapid braking to increase the ground area and increase the coefficient of friction are all braked by the weight of the traffic engine.The above braking methods have reached the limit of development. The development of a new braking system is urgently needed, and it generates an adsorption braking force against the inertia force, which is a physical law, and secures braking stability by shortening the braking distance, thereby preventing many personal injury and property damage. Economic loss, restoring loss of human dignity due to side effects of organ development The method can be minimized to be taken.

The present invention has been invented to solve the above-mentioned conventional problems and the like, and an object of the present invention is to provide an emergency and force majeure situation such as when a driving vehicle is running at high speed or when the road surface is slippery due to rain or ice. When sudden braking is required, the suction plate 50 which is a ground portion with the specially designed road surface 100 to increase the vertical load (adsorption load) without instantaneous additional kinetic energy and at the same time have an increased friction coefficient. ) To form a brush pin 55,

In addition, the value of the vertical load and friction coefficient, which are absolute constants, is increased to the braking force of the practice in addition to shortening the braking distance, suppressing the spin phenomenon generated during rapid braking at the same time, and overturning of the traffic engine. It is effective in suppressing the load on the front wheel of the car generated during rapid braking, and also when the turning force drops due to excessive adsorption load during turning, the steering wheel angular velocity sensor and body turning execution detection sensor Information is inputted to the central control unit (microcomputer), and calculated, output, and controlled to effectively adjust the vacuum degree in the suction plate 50 through the vacuum degree control device so that the turning force is restored and controlled, and instantaneous high power is applied. As necessary, various special energy and power generation methods are one of the core tasks of the present invention. It is one of the important tasks.

As mentioned above, the construction, action and effect are completed to reduce the braking distance in the force majeure situation, and the focus is on securing the braking stability such as suppressing the lateral slip of the vehicle, restraining the overturning force of the vehicle and restoring the turning force. The road is designed so that the road pavement rate is high and suitable for high-speed driving, and the road surface 100 has good smoothness, which is useful for the practical use of the present invention, and is an important variable.

In order to achieve the object of the present invention as described above, the adsorption plate 50 to form a ground portion with the road surface 100, the support section 30 for connecting the adsorption plate 50 to the vehicle body, and the adsorption load ( A brush pin 55 for friction with 100 to raise the friction coefficient, an energy source for driving the power generator, a power generator 80 for converting the supplied energy into power, and a vacuum for generating vacuum The generator 40, the lifting device for operating the lifting plate of the suction plate, the vacuum degree adjusting device for controlling the turning force, and all operations from the start to the end of the system are compared and calculated according to the set values according to the information input from various sensors. It is composed of a central control unit for appropriately controlling the output.

Hereinafter, with reference to the embodiment shown in the drawings the road surface adsorption brake system according to the present invention as described above assuming that the present invention is mounted on a vehicle.

As shown in Figs. 1A and 1B, the two-point support type support section 30 of the road surface adsorption brake system is made of high-tech materials and hollowed out to increase rigidity, and the body side portion is laterally connected to form an inverted A shape. The rigidity is increased, the upper end is connected to the vehicle body 20 by the vehicle body fixture 24 and the vehicle body fixing pin 23 coupled by a thin rubber bushing, and the lower end portion is connected to the suction plate fixture 34 to the suction plate fixing pin ( 35) is connected to the suction plate 50 by a one-point fixing method, and the mounting position may be installed at the center of gravity of the vehicle and at the rear of the vehicle. From time to time, the center of gravity is converted according to the condition of the road and the driving requirements, the braking force is balanced with the braking force of the front and rear wheels of the vehicle during the operation of the present invention, and changes from four-point braking force to five-point braking force In addition, the braking force acts at the center of the four-point braking force, which has the advantage of improving stability. However, the lowest ground clearance of the vehicle is the lowest, so the minimum ground clearance is lowered even more when installed. However, ECS (Electronic Controled Suspension System) device It will be able to make up for the shortcomings by adjusting the height of the vehicle, and the method of mounting on the rear part of the vehicle will provide a five-point braking force in addition to the four-point braking force, which ensures more stability. The effect of suppressing the slip phenomenon of the rear end of the vehicle is great, and above all, the biggest advantage is that the minimum ground clearance is high and the free space is large, so it is advantageous to install, and there are advantages in connection with various operation parts.

As shown in Figure 1b and 5, the suction plate 50 of the present invention is normally fixed to the bottom of the vehicle body 20 while receiving the spring 22 elastic force, the driver brakes rapidly, the accelerator return speed and the brake pedal When the operating speed and the master cylinder pressure information are transmitted to the central control unit, and the central control unit operates the system, when the fixture solenoid 77 of the elevator apparatus of FIG. 5 is operated in the direction of the arrow and the fixture 70 is released, the spring ( The suction plate 50 is rapidly lowered toward the road surface 100 by the elastic force of 22, and the descending speed is proportional to the spring 22 elastic force.

At this time, the wire 74 is connected to the suction plate fixture 34 and the wire pulley 71, and by the action of the sprocket 72, the lowering of the suction plate 50 is made to ground without great resistance.

Meanwhile, at the same time, the energy release signal is received from the central control unit, and as shown in FIGS. 14, 15a and 15b, the energy using the pressure gas and the combustion pressure of the chemical combustor is operated by the discharge device, and at the same time, FIGS. 11a, 11b and 11c. The vacuum generator 40 is operated to generate a vacuum, the vacuum generator 40 and the suction plate 50 is connected through a variable conduit 60, the generated vacuum force is filtered by opening the pipeline valve 66 1B, 3A, and 3B through 61, the road surface 100 is in close contact with the elastic force of the spring 22, and by a close contact with the pressing force on the circular friction ring tube 54, a simple closed space By sucking the air inside the adsorption plate 50 formed to form a simple sealed space below atmospheric pressure, such an action is made within 0.1 seconds, the filter 61 is enough to pass through the sand, water, etc. to be.

Due to this effect, the adsorption plate 50 has a force of close contact with the road surface by a differential pressure with atmospheric pressure, and as shown in FIGS. 4A and 4B, a woven fabric or a steel belt is inserted into the core to cover the friction ring tube having an elasticity and rigidity (57). ) Is deformed, and the friction ring tube 54 adapts to the curvature of the road surface 100 while being sensitively deformed by the air pressure in the inner space.

At this time, the circular arc of the friction ring tube 54 is a phenomenon that the circular arc becomes larger than before the deformation occurs, in order to offset this phenomenon, the friction ring tube upper cover 57 forms an angle K, the deformation in the tensile force It is composed of materials that can be easily made.

When the deformation is made, since there is a minute space between the friction pad 53 and the road surface 100 particles, air continues to be introduced by atmospheric pressure through this space, which is discharged from the vacuum generator 40 rather than the amount of air introduced therein. The amount of air should be more, and the faster the flow rate of the inflowing air, the lower the pressure due to Bernoulli theorem, so that the degree of vacuum inside the adsorption plate 50 is increased.

Next, the adsorption plate 50 will be described. The friction pad 53 having an exchange coupling structure is coupled to the bottom portion of the friction ring tube 54 when the above-described effect occurs. The ground pressure per area receives the vacuum pressure corresponding to the distance between the brush pin 55 and the friction pad 53 when the pressure of the spring 22 is divided by the arc and the adsorption load is generated, and the surface 100 slides at high speed. The high heat generated during the friction is cooled by the air introduced between the gap between the road surface 100 and the friction pad 53, and the material of the friction pad 53 is soft, so that the ground clearance is small, so that the adsorption force is good, but the wear rate is fast. If it is hard, the ground clearance becomes large, but the wear resistance is good and the material selection to adapt to high-speed friction is also an important problem. For example, at the ground diameter of the suction plate 50 at 38 cm, the road surface 100 Since Since Since the smoothness good, even assuming that the gap between the road surface 100 and the friction pad (53) 2mm intake cross-sectional area is 24cm ^2, yeogieda cast-iron excess is the intake cross section, of diameter 6cm sectional area 28cm ^2, the suction The vacuum force is a circular tube having a diameter of 6 cm, and the internal pressure may be formed for about 2.5 seconds at a degree of vacuum of 40 cm / hg, and the vacuum degree setting may be changed to an optimal state in consideration of all correlations.

In addition, as shown in FIG. 6, the core rod 51 is inserted radially in the center of the end face of the suction plate 50, and a woven fabric 52 is formed to prevent the plate from being bent due to frictional resistance. 55 are protruding, and are fixed by the fixing belt 59 as shown in FIG. 8, and the pin arrangement and fixing are various.

At this time, the adsorption force generates the friction force by elastically rubbing the brush pins 55 between the uneven portions between the particles of the road surface 100, and the braking effect per unit area is greater than that of the other friction material, so that the inside of the suction plate 50 is larger. Maximize the cross-sectional efficiency, the elastic deformation of the brush pin 55 is effectively adapted to the curvature of the road surface, and the sliding force is maintained because the adsorption force is greater than the friction force, this action force is applied to the support interval 30 It is transmitted to the vehicle body 20 by the vehicle body fixture 24 connected to the vehicle body fixing pin 23 to exert an additional braking force by the adsorption force not dependent on the weight of the vehicle, the length, thickness, of the brush pin 55 The friction coefficient changes according to density, elasticity, etc., and the high heat generated in the fin during friction is cooled by the air sucked to improve the wear resistance, and the total cross-sectional area of the brush pin 55 is the adsorption plate. (50) Set about 12% of the inner cross-sectional area, and if the effective diameter 38cm plate has a cross-sectional area of 136cm ^{2 and} the suction force is set to 500kg and the diameter of the pin is set to 0.4mm, the number of the brush pins 55 is about 90,000 For reference, the friction coefficient of the steel core brush of 0.4mm diameter measured by the inventors was 0.8 in normal road and 0.7 in wet road, so the friction coefficient between the normal road and wet road was small. If it is set to 0.8, the frictional load per pin is 4.4 grams (g), the length of the pin is about 2-2.5cm, and the long and the short ends make contact force with the road surface 100 good. It is fixed to the plate by about a degree, almost no damage to the road surface 100 by the brush effect, the limit of the sliding friction speed with the road surface of the brush pin 55 at high speed which is the most difficult in the present invention is the key, About this part Intensive research and technical development are required, and if it is commercialized, the maximum stable speed based on the experiment will be set.If the stable speed is exceeded, the operation is suspended and the system operates when entering the stable speed. By the degree of wear of the adsorption plate 50 is made, it is possible to use repeatedly.

As shown in FIG. 7, when the vehicle is turned, an angle displacement K 'is also generated in the left and right directions of the vehicle due to the centrifugal force, so that a gap is placed between the suction plate fixing member 34 and the suction plate fixing pin 35. By using a ball joint, such as using a joint material, the adsorption plate 50 has a complete contact force with the road surface 100 even when the angle changes in the left and right directions of the vehicle. In order to eliminate the phenomenon that the front of the adsorption plate 50 floats due to the friction force, the installation position of the adsorption plate fixture 34 can be moved to the front part, and the height H between the vehicle body fixture 24 and the road surface 100 and the support are The ratio of the length (l) of (30) is also a matter to be considered in the design, and if the length of the support 30 is short, the supporting force increases when the lateral force is received, but the drawability of the suction plate 50 is inferior.

When the risk factor is removed and the brake pedal 10 is stepped on by the driver, the master cylinder hydraulic pressure sensor outputs the operation termination and rapid return from the central control unit, and the pipeline valve 66 is closed to flow into the suction plate 50. When the vacuum force is interrupted, the suction plate 50 has only the force that the spring 22 presses, and the pressure that the spring 22 presses the ground is weak so that it does not interfere with the driving of the vehicle, and at the same time, the lift of FIG. When the gear motor 75 is operated to rotate the gear 73, the wire 74 connected to the suction plate fixing member 34 is wound by the wire pulley 71 formed on the same axis as the worm gear 78 that is engaged and operated. The fastener 70 is coupled with the fastener solenoid 77, and the suction plate 50 rises and returns to the bottom of the vehicle body 20 to temporarily remove the driving interference force of the vehicle to retain the driving ability.

When the braking force is applied when the vehicle is turning, the turning force drops, and the turning resistance must be accommodated to some extent, but when the turning restraint is large, the steering stability is insufficient. As shown in FIG. 16, the steering wheel angular velocity sensor and the body turning execution detection are detected. When the information input from the sensor is input to the central control unit and outputs that the turning force should be restored, the vacuum degree adjusting device is activated, and the output electrical action drives the motor as shown in FIG. 13 to reverse and reverse the motor gear 63. By rotating the gear 64 between rotations, the valve rotation time 65 is adjusted to open and close the pipeline valve 66 in the pipeline 60, and the vacuum degree of the inner surface of the adsorption plate 50 can be effectively and appropriately at any time and instant. It is controlled so that the maximum braking force and lane turning force can be obtained at the same time, and when the valve is closed, air is introduced into the ejector. In the case of a non-ABS vehicle, the turning force does not need to be greatly considered, and the design setting of the suction braking force is very important, and the efficiency of the ejector increases when the low vacuum is set, but the diameter of the suction plate 50 becomes large. Rational design, and theoretically can reach the weight of the vehicle, but it is determined by the turning force by the total weight of the vehicle, and 30 ~ 40% of the turning force is desirable. This increases the effect by more than 40%, which reduces the braking distance by 15-20% or more, and theoretically reduces the braking distance by 50%. Over steering occurs, but under steering occurs during operation of the present invention, so that the phenomenon can be neutralized to maintain a neutral handling action. In addition, the vacuum control device may be unnecessary by the suction braking force set point.

On the other hand, the system operation of the present invention does not operate at a low speed to prevent unnecessary operation, the road condition sensor can be operated at a low speed, such as freezing of the road surface, before the sensor is developed by manual setting It operates at low speed, and manual setting is canceled when road condition returns to normal.

Next, the energy source will be described. In the above description, the amount of air flowing out of the vacuum generator 40 is larger than the amount of air flowing into the space between the particles of the friction pad 53 and the road surface 100, so that the required adsorption force is increased. In order to obtain in the adsorption plate 50, it is required that the high power is drawn out for about 2.5 seconds instantaneously, and as shown in FIG. 15A, the gas is compressed and filled in the pressure tank to open the valve by the valve opening and closing solenoid during operation. There is a method of operating the generator 40 to form a vacuum.

Normally, it is possible to compress stable gas such as air and use it as energy, but the volume of the container becomes larger than the compression ratio, and the pressure difference between the initial pressure and the final pressure is large. Therefore, the use of liquefied carbon dioxide (Co ² ) gas, for example, can solve the above problems. Typically, 1 kg of liquefied carbon dioxide has a vaporization volume of 534 L at 15 ° C., and a pressure of 50 to 60 kg / cm. ^{With 2} pressures, it is possible to instantaneously draw high power and supply high speed fluid to the ejector, the pressure at the beginning of operation and the pressure at the end of operation are uniform, and it is possible to use refill by changing the container. Like this, shock sensor and temperature sensor are equipped to release liquefied carbon dioxide to the air to ensure stability. The mixture is injected under the mixture of oxygen and fuel filling the greater the lighter the ignition temperature, can be used a fluid of a high pressure as the driving force.

9 and 15b, the chemical combustor 90 is energized by the current flowing through the ignition coil 95 in accordance with the output of the central control unit, and the ignition wire penetrating the tube through the conductive pipe 98 by a chemical method. A high temperature is generated when the current flows through the current and the combustion pipe 98 explodes and ignites the combustion ignition member 99 so as to combust the combustion material 90 filled in the combustion cylinder 92 whose inner surface is insulated. The high pressure gas is guided to the power generator 80 or the multi-stage ejector 40 through the power generator entry pipe 97, and the chemical combustor burned is 2500 due to 1000cc of gas and 1000cal of energy and combustion reaction. It emits instantaneous energy of high temperature and high pressure of about -6000 ℃, and according to the chemical combustion method, it is possible to easily withdraw high power instantaneously, and the initial and end pressures are uniform, and the weight ratio Low and stable to impact In the case of a vehicle fire, it is combusted by the temperature sensor 94 to ensure stability, and the inlet of the combustion material is sealed by a diaphragm which can be ruptured by gas expansion, and the pressure fluid inlet pipe of the power generator or ejector Since the 97 and the combustion ash cylinder 92 are screw-coupled, it is easy to replace and install, and the shape can be freely modified, such as straight lines or curves, so that it is easy to install on a loading element. .

Next, the power generator 80 will be described. As shown in FIGS. 10A and 10B, the volumetric or turbo type power generator 80 requires a high speed rotation. The method for obtaining a vacuum through this method is complicated in structure and vacuum. Formation responsiveness is slow and there are difficulties in adoption.

Next, the vacuum generator 40 will be described. As shown in FIG. 11A, the vacuum generator 40 adopts the suction force of the air inlet of the centrifugal pump in terms of volume and weight, slow vacuum forming response, and low vacuum. Although there is a problem in the adoption due to the formation, the jet pump (aka Ejector) method of Figure 11b generates a vacuum without going through the power generator 40, and is simple and lightweight, volume adaptability is good and the multi-stage nozzle method (Stage) Higher vacuum suction volume and higher efficiency of vacuum can be obtained even with less energy than single-stage ejector. When the driving fluid is high temperature and high pressure, it shows excellent effect in forming vacuum degree by thermodynamic characteristics. Formation responsiveness is the best choice in the present invention because of the rapid formation response, and the degree of vacuum designed by the present inventors is set to about 40 cm / hg as the gauge pressure. The.

Referring to the method of supplying fuel to the multi-stage ejector as shown in FIG. 11c, the chemical combustion material forms a pressure gas of light weight and high temperature and high pressure, which is the most ideal, but it is not economical because it is expensive compared to other energy sources. The ejector is widely used in the industry because of its high vacuum formation rate even with a small high-pressure fluid.In the ejector using a high-temperature and high-speed fluid as a motive force, the ejector 44 pressurizes the fuel 44 pressurized and filled with the valve 43. When the vaporized or atomized fuel 41 is mixed and supplied to the front end nozzle or the intake air, it is mixed with the oxygen in the air sucked by the combustion gas of the high temperature (about 2500-6000 ° C) flowing in the nozzle 42, and the collision, In combination with spontaneous ignition combustion by a thermal reaction, additionally a high temperature, high velocity combustion gas is generated and the fluid flowing in the nozzle 42 by the sucked air This action is terminated at the end nozzles, and the middle and rear end nozzles have a large diameter to generate a large amount of suction force, and the considerations of the flame propagation speed and the expected air intake are to be provided. The amount is determined according to the mixing ratio with the expected intake air amount, and the expensive chemical combustor 90 is used as a driving force and additionally supplied fuel 44 is combusted to actually generate a lot of energy to generate vacuum. It is economical in terms of cost, and lower the cost by several orders of magnitude. For example, if the weight of the chemical combustion material (90) 50g, 50kcal combustion heat and 50gcl of gas production energy is summed up, the combustion fuel (44) If the weight is 50g, the calorific value is about 500kcal (11,000-11,500kcal / kg of hydrocarbon-based calorific value), and the sum is 600kcal, and 1ps is 0.1757kcal / sec in terms of power, 600kcal is 3,415ps, 2.5 In case of combustion reaction for 1 second, 1,365 ps of power per second was operated to convert the energy into power. In order to generate the energy as a chemical combustor, about 600 g of combustor is needed, No matter how poor the smoothness of the road surface 100, the efficiency of the multi-stage ejector is a variable, but the completion of the present invention by vacuum adsorption is not difficult, and the noise and the road surface of the brush pin according to the speed of the fluid discharged from the last nozzle of the ejector The friction noise level is estimated to be about 70 dB (decibels) and some noise and vibration should be tolerated in emergency and force majeure situations.

Next, the integrated air inlet 45 of the multi-stage ejector may be a plurality of passages, and the dust, sand, water, etc., which are stuck between the particles of the road surface 100 due to the brush action of the brush pin 55, are sucked away. By using the curve and the straight line, the straight suction is designed to separate the large inertia object and the curved suction is designed to separate the small inertia fluid. The discharge of the pipe causes the suction nozzle to flow into the rear end nozzle with a large suction diameter, thereby preventing the vacuum generating suction port from being blocked.

Next, as described above with respect to the smoothness of the road surface 100, since a large amount of vacuum can be formed by the energy as described above, even if there is a very poor smoothness of the road surface among the working distance, the degree of vacuum is instantaneous. In the concrete pavement, Groove is 2.5-3cm deep and about 2-3mm deep, but this cross-sectional area is only 1.8cm ² , which does not interfere with the adsorption force. The suction vacuum force is designed and set according to the road condition criteria.

Next, the central control unit will be described. As shown in FIG. 16, the central control unit includes an accelerator revolving speed measuring sensor, a brake pedal operating speed measuring sensor, a master cylinder hydraulic pressure sensor, a vehicle speed sensor, a steering wheel angular velocity sensor, a body turning execution detecting sensor, The information input from the vacuum level sensor, temperature sensor, shock sensor, road condition sensor, etc. is calculated by comparing with the inputted reference value, indicator, system start and stop, inoperable at low speed, gas tank valve open, open The valve angle of the material ignition and the vacuum degree control device is controlled to have the maximum braking force and the lane turning force by effectively controlling the vacuum degree in the suction plate 50 by effectively rotating the motor forward and reverse according to the output electrical signal. The accelerator speed sensor and brake pedal speed sensor The rotor cylinder oil pressure sensor is commercially available in the brake assist system (BAS), and the steering wheel angular velocity sensor is a sensor that outputs this angular displacement as an electronic signal when the steering wheel is given a certain angle of displacement. The sensor detects the actual turning amount of the vehicle body when a certain angular displacement is given to the steering wheel, and outputs as an electronic signal how much the vehicle body is turning against the steering wheel angular displacement, and the road surface condition sensor freezes the road surface. It measures the state and outputs it as an electronic signal, and other sensors are engineering practical, there are some unnecessary ones depending on the energy source among the sensors and mechanical elements, and many sensors are already commercialized and applied to vehicles. So take advantage of these.

And if it is commercialized, the rear light of the vehicle should be designed to exert a special visual effect to prevent the collision caused by the shortening of the braking distance, and publicity is also necessary.

As described in detail above, modern times are the age of high-speed driving because the time is golden, roads are designed and constructed to be suitable for high-speed driving, so the smoothness of the road surface is good, and the road surface of the traffic engine according to the present invention having high adsorption adaptability. Due to the additional vertical load increase due to the adsorption force of the adsorption brake system and the synergism of the friction coefficient, it actively responds to the inertial force, which is a physical phenomenon, to shorten the braking distance during sudden braking in emergency and force majeure situations, and to spin the vehicle. It suppresses the phenomenon and suppresses the overturning force of SUV vehicles with high center of gravity, and prevents accidents caused by quick steering wheel operation at high speeds.In particular, braking stability is improved when the road conditions are slippery due to rain or ice. Improved to prevent accidents, and to distribute the vertical load to the rear wheels It is a useful and commercially available invention that can prevent valuable human injury and prevent property damage due to the improvement of force and the increase of braking safety.In addition, the present invention is based only on the adoption of commercialization. It is considered that detailed follow-up studies are necessary, and it is thought that the first application will be applied to luxury cars, and the present inventors accumulate detailed technical matters than those described in the specification, and since the modern engineering has developed a lot, I think it can be easily commercialized.
