Eurasian wheel tread and euro turnout structure

Abstract

While promoting the Silk Road eXpress (SRX) line, which connects the Silk Road with a new railway of 20,000 km or more from the Korean Peninsula to Europe, in order to serve as a continental bridge connecting the Korean Peninsula, which is the starting point of the new Silk Road, with Europe, Asia, and the Pacific, there have been problems to be solved regarding different voltages and locomotive control systems between countries, as well as rail track gauges that differ from country to country and the use of different tracks (standard gauge and broad gauge). The rail gauges of major countries differ slightly, and Russia, Finland, and others use a broad gauge (16) (1524 mm), while Europe, South Korea, North Korea, China, Iran, Iraq, Morocco, and others use a standard gauge (1435 mm) (15). Thus, trains between countries cannot run interchangeably due to the use of different gauges, which leads to a technical problem. The present invention for improving the above problem provides a Eurasian wheel inclined tread structure (5) capable of freely rolling and running on the standard gauge (1435) and broad gauge (1524) sections of a railway by extending a wheel tread along an inclined tread section (1 / 20) of a wheel and configuring rail guides on the inner and outer sides of the wheel and a Euro turnout for branching a rail track, which is a railway, by improving same such that the wheel of the present invention can run.

Description

Eurasian wheel tread and Euro turnout structure

[0001] The wheelset of a railway vehicle is an assembly structure in which two wheels are pressed into the axle to form an integrated structure. With the help of bearings inserted into the bogie, the wheels rotate through rolling friction with the rails, allowing the vehicle to run. Each bogie has two wheelsets (axles), and generally, since one vehicle consists of two bogies, it is composed of four wheelsets. When power is transmitted to the wheelsets, the wheel tread surface runs on the railway rails. This relates to the shape of the wheel tread surface (1) that passes through a turnout for changing the course during rolling.

[0002] The wheelset of a railway vehicle is capable of rolling naturally without interference with points and crossings, without derailing when the bogie travels on the railway rails while moving in a meandering motion, and when passing through turnouts to switch from one track to another;

[0003] The wheel consists of a tire rim (7) that contacts the rail, a wheel tread with an incline, a rail guide (flange) that guides the wheel while rolling, a plate (8), and a hub (9).

[0004] When the SRX (Silk Road eXpress), which connects the Silk Road of over 20,000 km from the Korean Peninsula to Europe, is fully launched, in order to serve as the starting point of the new Silk Road and a continental bridge connecting Europe, Asia, and the Pacific, there is a challenge to solve the problem of different rail track gauges used in each country in order for railway vehicles to roll on each other, in addition to the different voltages and locomotive control methods between countries.

[0005] In other words, while the wheels use the same structure worldwide, the rail gauges differ. As shown in FIG. 6 and 7, the rail gauges of major countries are broad gauge (1524 mm) (16) for Russia and Finland, and standard gauge (1435 mm) (15) for European countries, Korea, North Korea, China, Iran, Iraq, Morocco, etc., so the rail gauge widths are different. Therefore, it has become necessary to improve the wheels with a new structure and the switches that run on them to provide a technical solution so that trains can run mutually between countries.

[0006] The present invention for achieving the above objective is,

[0007] In order to enable natural rolling travel from the standard track (1435mm) of Korea, through broad tracks (1524mm) such as those of Russia and Finland, and then on the standard tracks of each Europe, the inclined tread surface (1 / 20) of the tire rim of the wheel is extended to widen the wheel width (18) so that rolling friction travel between the standard track and the broad track is possible. Additionally, the inclined tread surface (5) of the wheel is extended to improve driving performance, such as meandering, on the two conventional tracks (standard track, broad track), and rail guides (flanges) are configured on the inner and outer sides of the wheel.

[0008] In the above-mentioned inner wheel guide (2), a new outer wheel guide (3) (for broad tracks) is formed and integrated along the wheel inclined tread (1 / 20), which is the wheel diameter center (13, 14), and the plate part and the hub part are formed to form a wide-structure Eurasian wheel inclined tread (5) with sufficient strength and rigidity;

[0009] The present invention provides a new wheel tread structure that improves the wheel tread structure of the present invention so that a Eurasian wheel is pressed into a conventional axle (axle for standard track and broad track) to enable rolling friction driving on standard track and broad track with different gauges without special mechanical devices, thereby providing a Eurasian wheel inclined tread structure (5) that runs on the Silk Road from the Korean Peninsula to Russia and Europe.

[0010] In addition, for the wheelset having a Eurasian wheel tread according to the present invention to naturally travel on conventional standard and broad rails, a transfer rail zone (Transfer Rial Track Zone) of FIG. 11 is required to allow travel on rails where the rail width gradually widens or narrows, in order to pass through the standard rail (1435) (15) as in FIG. 11 and enter the broad rail (1524) (16) gauge. Just as there is a conventional point section (25) in a Euro-point switch for converting a conventional train from one rail track to another as in FIG. 10, where the inner wheel travel guide (flange) travels without interference, a Euro-point section (26) in FIG. 12 is provided to allow the outer travel guide (flange) of the Eurasian wheel tread to roll on the running rail track without any interference, and a U-shaped groove (width 40, depth 40) is cut to avoid interference. By doing so, the outer guide of the wheel was also configured with a structure that avoids interference with the turnout during rolling.

[0011] Furthermore, the Euro-Crossing section (27) at the end of the turnout in Fig. 10 is improved from the conventional triangular crossing (29) structure of Fig. 8 into a rhombus-diamond shaped Euro-Crossing section (27), thereby providing a Euro Turnout like Fig. 10 that comprises a Euro point and a Euro Crossing, allowing the Eurasian wheel tread surface having inner and outer wheel guides according to the present invention to branch and travel on the rail track without interference.

[0012] In the railway vehicle having a wheel axle and a turnout structure of a bogie with a Eurasian wheel tread structure configured to allow the wheel running on the railway according to the present invention to freely run on the standard track of Fig. 6 and the broad track of Fig. 7, compared to a railway vehicle that attempts to manufacture a new wheel axle and bogie for operation, the wheel of the Eurasian wheel tread structure (Fig. 5) of the present invention applies a Eurasian wheel tread structure as shown in Fig. 9, which is pressed into a conventional axle, and resolves the problem of interference with the rolling wheel by improving the Euro-point, tongue rail, and Euro-crossing as shown in Fig. 10, by simply cutting out a part of the rail component turnout that interferes during operation in a U-shape as shown in Fig. 12, in the point and crossing parts of the conventional standard track and broad track turnouts intended for operation.

[0013] In addition, a V-shaped transfer track zone (Transfer Track Zone) is established at the connection point between the standard gauge and broad gauge sections, which are different gauges between countries, as shown in Fig. 11. This allows the train to naturally connect from the standard gauge to the broad gauge rail, enabling it to freely run on the tracks without the need for complex mechanical devices or new bogies between the tracks, and thus the invention of the Eurasian wheel tread structure and the Euro switch structure.

[0014] The effect of the present invention can greatly contribute to the Silk Road Express (SRX), a continental bridge connecting Europe, Asia, and the Pacific, by connecting the nearby Trans-Korean Railway (TKR), Trans-Siberian Railway (TSR), Trans-China Railway (TCR), and European railways.

In the Euro turnout of FIG. 1, starting with the standard rail cross-section (19a) and the broad rail cross-section (19b), (21) is the Eurasian wheel axle, (22) is the standard track gauge (1435), (23) is the conversion track rail section (1435<-->1524), and (24) is the broad track gauge (1524).

(30) is the Euro crossing which is a groove (40x40) that removes the interference between the wheel guide and the U-shaped groove.

[0032] In order for our train to travel along the Iron Silk Road, we intended to invent an integrated Eurasian wheel tread structure (5) in which the wheel tread (1 / 20) is extended from the tire rim of the wheel to allow the train to travel from the standard gauge (1435mm) of Korea through the broad gauge (1524mm) of Russia and Finland, and then run on the standard gauge of each Europe, so that the wheel tread width is widened to allow rolling travel between the standard gauge and the broad gauge, and just as curved travel and branching are possible by the inner (2) driving guide (flange) of the wheel in the standard gauge, a driving guide (flange) is configured on the outer (3) of the wheel in the broad gauge (1524).

[0033] The invention provides a Eurasian wheel slope tread structure (5) that allows rolling without large technical devices, in accordance with the procedure of mounting a wheel axle, which is a conventional axle (6), with the Eurasian wheel structure of the present invention pressed into a conventional axle, during the conventional wheel replacement period, which is the life cycle maintenance period.

[0034] In addition, for the wheel axle with the Eurasian wheel pressed in according to the present invention to freely roll between the standard track section and the broad track section, as shown in FIG. 10, a transfer rail zone (23) is required in which the width between the two rails widens or narrows in reverse so that the wheel can roll on the rail while the width gradually widens, and just as there is a point section (25) on the inner side of the rail track in the Euro turnout of the present invention, a Euro-point section (26) having a U-shaped relief section on the outer side of the rail track is configured, and a cross (27) in the shape of a diamond is configured at the end of the turnout.

[0035] In FIG. 12, a Euro-Crossing section (27) is configured to eliminate interference by forming a U-shaped groove (width 40, depth 40) for eliminating interference by the wheel guide at the crossing and point, thereby forming an escape space, so that the Eurasian wheel of the present invention can roll freely without interference with the structure of the Euro-turner, and the Eurasian wheel tread surface and the Euro-turner are provided.
