2.Guideway Bus

A guideway bus is a bus that is operated by a driver on a general road, but automatically operated by a guideway system on a dedicated track.This means that a bus runs on a guideway or a dedicated passage. The problem with this guide system is that a separate guideway must be provided and the transportation system must be adapted to this system. In addition, it is pointed out that the guideway, which is a dedicated passage, cannot be shared with other road traffic.

3. Problems with trams and city buses

Streetcars and city buses served as a means of complementing the public transportation network with mass high-speed transportation in the metropolitan area. However, due to the rapid increase in the number of cars owned, road traffic is very crowded and the traffic is so severe that facial expressions are slowed down and the running time is not constant. In particular, due to poor service level, the difficulty of operating the trams and buses due to the decrease in the number of passengers has resulted in the elimination of part of the route or the frequency of operation. As a result, the impact of road congestion and air pollution on the environment due to the congestion of automobile traffic is a big problem in the city.

The present invention meets the necessity of a new urban transportation system that meets transport demands and manageability and has low construction and operation costs due to the enormous increase in the construction and operation costs of public transportation such as subways, as well as various problems of urban transportation as described above. In order to meet the demand, it is inexpensive construction and operation cost, and aims to provide eco-friendly transportation which is less pollution and economical compared to existing transportation facilities.

The present invention consists of a rail installed in the excavation to excavate the road surface and the noise and vibration prevention fillers filled in the excavation, the rail upper surface of the rail is installed to be the same height as the road surface, the noise and The anti-vibration filler provides a central guided single rail track, characterized in that it is filled in the excavation portions other than the upper edge of the rail and the upper surface of the rail.

In addition, the central guide system further comprises a single rail track, characterized in that it further comprises a rail support provided on the rail bottom end of the rail.

The center guide system further comprises a single rail track, characterized in that it further comprises a non-slip pavement or driving direction guide grooves formed on the road surface on the left and right sides of the rail in parallel with the traveling direction of the rail.

The present invention constitutes a wheel for driving the single guide rail track, the radially extending along the circumference of the running surface and the running surface of both sides of the width added to enable the curved running on the width of the upper rail surface, respectively It provides a central guide type single rail track 2 flange guide wheel, characterized in that consisting of a protruding flange.

In addition, to configure a driving vehicle for driving the central guide type single rail track, the vehicle body; An engine installed in a lower space of the vehicle body; A generator powered from the engine; A drive motor that receives electric power from the generator and converts it into a driving force; The central guide type single rail track comprises a driving wheel which is installed at the front and rear of the lower end of the vehicle body while receiving a driving force from the driving motor, and a guide wheel which is installed at the center between the driving wheels and travels the upper surface of the rail. It further includes a tram car.

In addition, the engine further includes a central guided single rail orbit tramcar, characterized in that the liquefied natural gas internal combustion engine.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a cross-sectional view of a two flange guide wheel 400 passing over a rail 100.

2 flange guide wheels 400 consisting of a flange 420 protruding radially from both ends of the guide wheel running surface 410 of the running surface width of the two flange guide wheels.

Conventional wheel 10 is a guide device for guiding the balance of the vehicle from the side as shown in Figure 6 is one flange on both sides of the wheel or two separate guide wheels are installed as shown in FIG. The structure itself was complex and the rails themselves were large and heavy. In the case of such a complicated structure, the production is more complicated and manufacturing costs are higher than the existing wheels, and the frequency of the balance is high during operation.

Therefore, the two flange guide wheel 400 of the present invention is different from the shape of the flange 30 of the conventional wheel on one side of the running surface of the conventional wheel 10 of Figure 6, on both sides of the guide wheel running surface 410 By forming the flange 420 to prevent the separation of the two flange guide wheels 400 passing over the rail, it was configured to serve to guide the direction of travel of the two flange guide wheels 400.

In addition, since the two flange guide wheel 400 is made of steel, it was configured to bear a part of the vehicle load as well as the guidance of the vehicle direction.

In FIG. 1, the two flange guide wheels 400 have a width of the upper rail surface (answer surface) 110 and a guide wheel running surface 410 having a width that does not interfere with the progress of the vehicle.

The conventional wheel 10 (which combines the functions of a guide wheel and a driving wheel that carries the weight of a vehicle) for driving a general railway (including high-speed rail and subway) is equipped with two driving wheels for each axle. . Since one axle consists of two wheels with one flange, there is two flanges for each axle.

With the structure of the conventional wheel 10 as described above, the vehicle of the general railway (including high-speed railway, subway) is running to date.

The present invention bears the weight of the two flange guide wheel 400 and special vehicle having two flanges 420 on one axle of the general railway and the driving wheel 520 for driving exclusively, so It is possible to drive the vehicle with the same function.

<Table 2. Comparison between General Railroad and the Wheel of the Invention>

General railway Two guide and drive steel wheels with two flanges on one axle (two flanges) The present invention Two driving tire wheels on one axle, one steel wheel with two flanges

The bogie structure and its rotation principle are as follows.

The bogie in a railroad car is between the body and the rail and is an important part of running on the rail by wheels. There are various structures, but the main parts are the bogie frame, the wheel, the axle, the bearing box, the spring and the swing bolster. A trolley | frame is a frame of a trolley | bogie, and each part is comprised by this. Inside the bearing box is a bearing, which supports and rotates the end of the axle. At the center of the upper swing bolster is a center plate, where the body's pins are placed to receive the weight of the body, and the bogie can move freely around this pin. Can pass. Such a bogie is called a bogie bogie, and a vehicle with bogie bogie is called bogie.

In addition, there is a spring between the upper swing bolster and the lower swing bolster or between the bogie and the bearing box to reduce vibration. The spring has a coil spring and a leaf spring, and recently, an oil damper or an air spring is used instead of the steel spring. One bogie usually has two axles (and therefore four wheels), such a bogie is called a two-axis bogie and sometimes a three-axis bogie. A trolley without a drive system used for a passenger car is called a vertical bogie, and a bogie with a driving motor is called a power bogie.

2 is a cross-sectional view showing a rail 100 for guiding a driving direction of a single rail track tramcar.

In this embodiment, the rail 100 is used by embedding the road surface 300 and the rail upper surface 110 to be the same plane using a rail for general railway. By doing so, it is possible to share the road with existing cars, thereby saving the cost of creating a separate road and increasing utilization of the road. However, if necessary, a special type of dedicated may be produced and carried out.

The conventional new tram used a conventional special rail 40 traveling exclusively. A representative one is shown in FIG. In the case of using such a structure, the rails must be manufactured separately, and the wheels running on the rails had to be manufactured to suit the conventional special rail 40.

In contrast, the present invention minimizes the installation cost by using a rail for general railway, and the rail upper surface 110 is buried to be flush with the road surface 300 is characterized by the present invention.

And in the embodiment of Figure 2 excavating the road surface 300 to have a rectangular cross-section and install the rail support 150 to the bottom of the excavation surface, then install the rail 100 on the bottom of the excavation surface, the upper rail Noise and vibration prevention filler 200 is placed on the excavation surface except the edge of 120 to install a noise vibration prevention facility. The problem of the existing tram was excessive noise and vibration. As shown in the figure, noise and vibration prevention fillers 200 were installed around the rails, so even if the rails were operated, the noise and vibration emission regulations prescribed by the Noise Vibration Regulations Act. Noise and vibrations below the standard (Exhibit 10 of the Enforcement Regulations of the Noise and Vibration Control Act) were created to create a pleasant traffic environment.

Here, the noise and vibration prevention filler 200 is used to reduce the noise and vibration by using mortar, asphalt, cement, and the like.

3 is a side view of an embodiment of a tramcar passing over the rail, and FIG. 4 is a bottom, cross-sectional and side view of the central guided single rail tramway.

First, there is a window on the side, there is a front and rear door, and there is a vehicle body 500 supporting the cabin, and two bogie structures 510 are installed at the front and rear of the bottom of the body 500. After the two flange guide wheels 400 are installed in the same axle as the traveling wheels in the center between the wheels of each of the two axle bogies 510, the driving wheels 520 of the two axle bogies 510 are operated. The drive motor 530, and the engine 540 and the generator 550 installed in the lower space in the middle of the vehicle body are installed.

First, the vehicle body 500 used in the manufacture of the present invention uses a vehicle body for general railway. In addition, two two-axis bogie structures 510 having two pairs of driving wheels 520 are installed at the front and rear of the lower end of the vehicle body. In this case, all four axes of the two two-axis bogie structures 510 are manufactured as drive shafts. In addition, when the vehicle is organized in two or more vehicles, it is possible to operate by interlocking operation.

The drive shaft drives the drive wheel 520 back and forth with a drive motor 530 mounted to each axle of the two-axis bogie structure.

The driving wheel 520 except for the two flange guide wheels 400 is a rubber tire wheel, and an auxiliary safety steel wheel is mounted inside the rubber tire wheel to maintain vehicle safety when the rubber tire is damaged. The driving wheel 520 is a tire wheel that is currently manufactured by a tire manufacturer as a driving rubber tire wheel that is adopted by other existing road traffic means.

And the two flange guide wheel 400 uses the one described in Figure 1 above.

The driving wheel 520 and the two flange guide wheel 400 are mounted on the axle of the two-axis bogie structure 510 in the same size.

An engine 540 and a generator 550 for providing a driving force to the two-axis bogie structure 510 are installed in the lower portion of the vehicle body between the front and rear bogie structures 510. The generator 550 receives power from the engine 540 to generate electric power to operate four driving motors 530 at the front and back of the generator 550 to drive and drive the driving wheel 520. Unlike the structure of a general vehicle, in the case of a long car body such as a passenger car of the train, it is structurally difficult to transfer the power generated by the engine 540 to the drive shaft as it is and structurally difficult to lose energy. Therefore, the present invention adopts a configuration in which the loss is minimized in terms of energy, and generates electricity through the generator 550 by using the power generated in the engine 540 and then transfers it to the drive motor 530 to generate driving force. It was.

The reason for using the engine 540 as a power source is that in the case of a conventional tank, a separate overhead network must be installed along the driving route. In other words, a separate wire installation space is required. As a result, it is not aesthetically pleasing and the high-voltage wire is located in the upper space of the road, which is a significant risk for pedestrians walking under the wire, unlike the subway which is safe for passengers. Therefore, the present invention minimizes the risk of the conventional tram as described above by obtaining power from an engine such as an internal combustion engine although there is energy loss.

In addition, the engine 540 may be configured as a liquefied natural gas (LNG) internal combustion engine rather than a gasoline or a diesel engine having severe air pollution. Liquefied natural gas (LNG) internal combustion engines burn water and carbon dioxide by almost completely burning natural gas, so the amount of smoke is very small. Therefore, it is possible to realize the advantages of eco-friendly transportation by using liquefied natural gas internal combustion engine.

As described above, the directionality of the single rail track tramcar is secured by the two flange guide wheels 400 mounted on the vehicle and the rails 100 embedded in the road surface.

The combination of the vehicle 500 may operate in one to four cars according to road conditions and transportation demands. In addition, when two or more vehicles are organized and operated, a deflectable connector that can be rotated and operated in a curved course is used to minimize the radius of the driving plane curve so that the existing road is used as it is. More detailed operation is described later.

The operation method of the above-mentioned central guided single rail track tramcar is as follows.

주행 Drive and operate like a normal railway. In other words, unlike a car, it travels like a normal railway by a rail that guides the direction without a steering wheel.

In the cab of the tram car, it has a power switch function, forward and backward driving functions, acceleration and deceleration operation functions, and a stop function.

The driving (running) method of the above-described central guide system single rail orbit tram is as follows.

① The system should be operated by using two lanes in two directions with the same system as the bus central lane system currently in force in Seoul.

② Adjust the minimum flat curve radius according to the two-axis bogie structure and the length of the vehicle and the width of the facility limit of the road.

③ Set the riding capacity, size of the vehicle, and driving force to drive the existing terminal gradient.

④ The number of vehicles should be organized appropriately to meet the demands of transportation and road conditions. Tickets shall be made using automatic ticket gates / electronic boarding cards.

The intersection driving method of the above-mentioned central guide system single rail orbit tram is as follows.

In the case of flat crossover, the tramcar priority signal system improves the flow and speed of driving.

Over Overpass / Under pass facilities will be installed to ensure the exclusive driving route to improve operating efficiency.

 ㉢ Safety zones are installed at passenger stations and passenger overpasses are constructed to protect the safety of passengers and to prevent other road traffic.

Tramcars in which a failure occurs are special structural vehicles equipped with guide wheels and are quickly towed to the vehicle base to shorten the normalization time of operation. In addition, the rescue special vehicle is equipped with a guide wheel on the front and rear bumpers to enable the vertical operation to ensure the mobility on the road.

• Interlocking signals and crosswalk signals are interlocked with the tramcar signals to ensure driving speed.

(2) Branch facilities shall be provided on the central guide rail to enable branch line operation.

5 is a plan view and a cross-sectional view showing that the non-slip packing 600 is installed on the road surface 300 of the drive wheel exclusive path 310 through which the drive wheel 520 passes. When rain falls on the road surface 300 or when snow accumulates, the friction between the road surface 300 and the driving wheel 520 is reduced, which may cause obstacles in the driving of the driving wheel 520. In order to solve this problem, the present invention is dedicated to the driving wheel 520 or more than the width of the driving wheel 520 on the road surface 300 through which the driving wheel 520 passes in order to increase friction between the driving wheel 520 and the road surface 300. By setting the furnace 310 to install the anti-skid packaging (600). However, the height of the anti-slip pavement 600 is almost the same as the road surface 300 so that there is no problem in sharing the road with other transportation.

Aggregate used in the installation of the anti-slip packing 600 is a driving wheel made of rubber tires using natural aggregates having excellent polishing resistance, sliding resistance, and crushing resistance according to the standard of the anti-slip packing specification or steelmaking slag which is a by-product of smelting. 520 is constructed on the road surface 300 passing by.

In addition, in addition to the non-slip pavement 600 on the road surface 300 passing the driving wheel 520 may be provided with a driving direction guide groove 610 to assist the driving direction on the floor. The driving direction guide groove 610 serves to guide the wheel not to deviate from a predetermined track and to guide discharge through the groove when there is water on the road floor. 5 is illustrated.

When the track in which the rubber tire driving wheel 520 passes is curved, the surface passing by the wheels outside the curvature is higher than the inner side so that the one-sided slope treated to cope with the centrifugal force is the same as the general road surface design method.

Effects resulting from the practice of the present invention are as follows.

First, it secures convenience and accessibility with low-rise vehicles such as an improved streetcar using the existing road surface.

Second, by laying a single rail track for central guidance under the existing road surface, the existing road is used as it is compared to other new traffics, thus greatly reducing facility construction costs and shortening the construction period.

Third, it possesses the same transportation capacity as the existing automatic guideway system (AGT) and guideway bus. In addition, by improving the linearity of the road, it is possible to secure superior transportation capacity than the existing new transportation means by adopting the central guide road single track and the steel wheels for the two flanges.

Fourth, the construction of traffic environment such as improvement of driving speed of other road traffic, improvement of transportation capacity, and safe operation by installing passenger overpass at stop and three-dimensional intersection.

Fifth, the use of existing high-end bus vehicles, rubber tire wheels, and general railroads, which are produced in Korea, promotes the promotion of domestic related industries, which can lead to import substitution effects.

Sixth, the present invention, like other new traffic, there is a dedicated passage, but it is possible to share with other road transportation means, such as a general vehicle.

Seventh, the implementation of the present invention can simplify the power transmission system of the engine, generator, and drive motor structure, and can create a pleasant traffic environment by operating a streetcar with less noise and vibration even in a city with heavy traffic. In addition, the maintenance and management cost is reduced compared to the existing rail system, so it can be introduced in small and medium cities with low financial independence. When the internal combustion engine is liquefied natural gas (LNG), there is almost no smoke and processing power. There is no need to install supply facilities, which can improve the urban environment.
