Description

The invention relates to a device for a railway track and can be used in the construction and repair of turns of railway and tram tracks, the subway, attractions such as Roller Coasters and Children's Railway, children's toys. A railroad is known that contains two guide rail tracks formed by rails joined with a gap, the ends of which on each track are parallel to each other and made in mutually intersecting planes with the ends of the rails of the other track, while the angles formed by the center line of the track and its projection onto the plane, in where the ends of the rails of one track are made, are not equal to the angles formed by the center line of the path and its projection onto the plane in which the ends of the rails of the other track are made (application for invention of the Russian Federation No. 2007133349 dated 09.09.2007).

However, the well-known railway does not take into account the effect of the shift of the center of gravity of the vehicle when cornering, which leads to emergency situations, shortening the life of the railway track and rolling stock, and harmful noise impact on the environment.

The specified railway is the closest analogue of the invention.

The technical result of the invention is to increase the speed and safety of traffic, increase the operating life of the railway, rolling stock, trams, subway cars, attractions, reduce energy costs and noise impact on the environment, and also allows you to reduce the radius of curvature on turns when laying railways when maintaining the speed of vehicles.

The technical result is achieved due to the fact that the railway, containing two guide tracks formed by rails joined with a gap, contains at least one section, the center line of which is a segment of a smooth curve, while the angles formed by a tangent to the center line at a point its intersection with the plane in which the ends of the rails of the outer guide track are made, and its projection onto the plane, is less than the angles formed by a tangent to the center line at the point of its intersection with the plane in which t Lets of rails of an internal directing track, and its projection on the specified plane.

The drawing shows a section of the railway, top view.

The railway contains guide rail gauges (hereinafter gauges) 1 and 2, formed by rails docked with gaps 3 and 4.

The ends of the rails 1 and 2, the distance between which forms the gaps 3 and 4, respectively, are in the mutually intersecting planes m and n.

The center line 5 of the railway section is an arc of a circle.

Tangent 6 to the center line 5 at point A of its intersection with the plane m, in which the ends of the rails of the outer track 1 are made, and its projection onto the plane m form an angle α with vertex A.

The tangent 7 to the center line 5 at the point B of its intersection with the plane n, in which the ends of the rails of the inner track 2 are made, with the plane n (in the general case, with the projection of the tangent 7 to the plane n) form a right angle β.

Obviously, the smaller the angle α, the vehicle makes a smoother run over the end of the receiving rail of track 1. At the same time, the energy consumption for moving the vehicles is reduced, since the shock destructive loads on the end of the subsequent rail from the side of the wheels of the vehicle and the noise impact on the environment are reduced environment (including passengers), the service life of both the railway and vehicles moving along it increases, and traffic safety increases.

/2, нагрузки на торцы рельсов внутренней колеи будут наибольшими. Однако указанные нагрузки можно уменьшить путем перемещения центра тяжести транспортного средства в сторону внешней колеи.When the angle β is equal to

/ 2, the loads on the ends of the rails of the inner track will be greatest. However, these loads can be reduced by moving the center of gravity of the vehicle towards the outer track.

The railway is operated as follows.

The movement of vehicles by rail is carried out at bends at maximum speed. This becomes possible due to the fact that in the area of joints on the ends of the rails of the outer track the wheels of the vehicle produce a smooth collision with less destructive effect. This is especially important when the center of gravity of the vehicle is shifted towards the outer gauge, caused by centrifugal forces at high speeds on the railway, when the loads on the rails of the inner gauge decrease and the loads on the rails of the outer gauge increase. As a result, not only the destructive effect on the inner track rails from the side of the vehicle wheels is reduced, but also the knock of the wheels in the joint area becomes quieter. At the same time, the loads increasing on the outer track do not lead to destructive shocks, but are compensated in the area of the joints by beveling of the ends of the rails.

It becomes possible to choose a high-speed mode of movement of the vehicle, in which the loads acting on the ends of the rails, the region of which is the weakest point of the track, are appropriately distributed along the rails of the inner and outer tracks. In addition, when laying a railway with a turn, it is possible to reduce the radius of curvature of the railway by decreasing the angle α, without reducing the speed of the vehicles on the railway and without increasing shock loads at the junction of the rails.

Thus, it becomes possible to apply a method of operating the railway, including the movement of vehicles along it at a speed at which the shift of the center of gravity of the vehicle occurs towards the outer guide track. By setting the maximum shift of the vehicle’s center of gravity towards the outside gauge according to safety conditions, it is possible to achieve the optimal mode of movement on the proposed railway, the movement with the highest speed and minimal energy consumption.

The proposed railway allows for the safe movement of vehicles at high speed. The shift of the vehicle’s center of gravity at high speeds towards the outer track 1 increases the load on the track 1 rails and reduces the load on the track 2 rails. At the same time, the impact force of the vehicle wheels on the ends of the receiving track 2 rails decreases, which increases the life of the railway and vehicles, reduces the noise impact on the environment and energy consumption, at least by a hit on the edge of the receiving rail of track 2 and its destruction, the production of noise.

The increase in load on the rails of track 1 is compensated by the design (increase in angle α) of the ends of the rails.

Executions of the railway are proposed in which:

- the axial line of the railway section in the form of a smooth curve is an arc of a circle;

- the ends of the rails of the inner guide track are made in the plane of the cross section of the rails.

The method of operation of the railway, including the movement of vehicles on it, is that the movement of vehicles is carried out by rail according to any of the above versions, including at an optimal speed.

The proposed railway and the method of its operation are industrially applicable, have novelty, are not explicit to the average specialist.
