Description

The invention relates to the field of movement of passenger trains over short and long distances.

High-speed trains are known for their movement on a double-rail type railway placed on sleepers in a stone dump.

High-speed trains are also known, moving with an air gap relative to the track, which is ensured by the force interaction of the magnetic (electromagnetic) systems of the track and train.

Known methods have a common and significant drawback:

exerting strong pressure on the supporting nodes of the canvas, and at high speeds experiencing dynamic and overload of an oscillating and resonant nature. All this requires high costs to ensure the safety of high-speed traffic and additional engineering and technical innovations that complicate the design of the canvas and trains and reduce their reliability.

Closest to the claimed invention is a technical solution - a project of Aero-Train University of Tohoku, Japan (http // www.molodejno.ru), in which a train - an aircraft with wings, having control in three planes, moves along a wide guide channel, not touching its surfaces, reaches a cruising speed of 500 km / h through propeller engine screws. The shortened wings create the lifting force of the transport according to the principle of an ekranoplan, and the role of the supporting surface for the wings is played by a trough, inside which a flying train - an airplane moves at a small height above its lower part. This decision is complicated by the need for constant computer control of the course of transport and its position relative to the lateral surfaces of the trench and flight altitude, which reduces the overall reliability and safety of the transport. In addition, the propeller propellers during the movement process, as in aircraft, will create increased noise for both passengers and residents of settlements adjacent to the road. In this case, the pressure of the weight of the flying train will be completely transmitted to the supports of the gutter, since the wings of the transport create pressure on the air inside the gutter to its lower part.

The objective of the invention is the provision of high-speed comfortable and safe passenger traffic over short and long distances along a single track in one and the other direction with a partial separation of the train weight from the overpass canvas.

As a result of the use of the present invention, the pressure on the support nodes of the canvas decreases at high speeds experiencing dynamic overloads of an oscillatory and resonant nature, costs are reduced to ensure the safety of high-speed movement without additional engineering and technical innovations that complicate the design of the canvas and train and reduce their reliability.

The technical result is achieved by the fact that in the proposed method of high-speed movement of a passenger train on a single-track railway, including the movement of rolling stock by rail, the movement of the train is carried out on a single-track track placed on supports, and the pressure on the bearing supports and the track is determined from 5 to 15 percent of the weight of the train at a cruising speed of the train of 350-400 km / h, the wings of the train cars create a lifting force with a fast incoming air flow, thereby the weight of the train from the bearing support nodes of the road by means of wings to the air, while the track is branched into two or more branches in the places of a short stop or stop of the train, and such stops are made every 100-200-300 km of track in populated areas, and provide through movement in one and the other direction simultaneously on a single track road.

The result is also achieved by the fact that in the device for the high-speed movement of a passenger train along a single-track railroad containing rolling stock with wagons, each wagon of the train is equipped with wings that are built into the body of the wagons, creating a lifting force with high-speed incoming air flow, thereby moving the pressure of the train weight from bearing support nodes of the road to the air, while the wings are made with such parameters that, at a cruising speed of the train of 350-400 km / h, the pressure on the bearing supports and the canvas is from 5 t up to 15 percent by weight of the composition, wherein the wings are arranged on the train wagons, at least one wing on the wagon.

In another embodiment of the device for high-speed movement of the wings are mounted on the side surfaces of each carriage along its entire length.

In another embodiment of the device for high-speed movement of the wings are placed above the roof of the car.

In the proposed rolling stock, the dimensions and shape of the bearing wings of the cars are selected according to the principle of the least cost of their manufacture, reliability of construction, simplicity and design.

To eliminate these and other concomitant disadvantages, the following method of high-speed train movement on a single-track railway is proposed.

The train moves on a one-way track. The canvas forks into two or more branches in places of a short stop or train stop, and such stops are made every 100-200-300 km of the track, in settlements. This ensures the ability of a single-track road to move through in one and the other direction at the same time.

The train is equipped with wings built into the carriage body of such parameters that, at a cruising speed of the train of 350-400 km / h, the pressure on the bearing supports and the bed is from 5 to 15 percent of the train’s weight, while the moving parts of the train experience significantly lower power and dynamic loads.

The device of the train is such that each carriage of the rolling stock is equipped with wings, which create a lifting force with a high-speed incoming air flow, thereby transferring the pressure of the weight of the train from the bearing support nodes of the road to the air.

At the same time, part of the weight remains invariably on the road supports and the web, as it provides grip for the drive to drive through the wheel pairs.

Such a device of the road and train will increase the reliability of the nodes of the road and train, their durability and protect people and fauna from a possible meeting with the high-speed train, as well as reduce the cost of construction and maintenance of the road.

The wings of the train can be placed both on the side surfaces of the cars, and above the cars. The dimensions of the load-bearing wings are calculated based on the average cruising speed of the train, its average load by passengers and the required power adhesion of the wheelsets to the road.

This method and arrangement of the road and train will significantly increase high-speed communication between various settlements, starting from a distance of 100 km, acting as an uncontested high-speed vehicle having stops after almost every 100 km of the way. When the speed is half the speed of the airplane, it stops like a regular passenger train.

The purpose of this device is to transport passengers at high speed over short and long distances, with all the necessary conditions for comfort and safety.

The essence of the invention is illustrated in figures 1, 2, 3 and 4.

Figure 1 presents a General diagram of a device for high-speed movement of a passenger train on a single-track railway.

Figure 2 - wings are placed on the roof of the car.

Figure 3 - cross section of the device with wings on the side surfaces of the cars: a) - the wings are placed above the level of the canvas, b) - the wings are placed at the level of the canvas.

Figure 4 is a top view of the track with two sleeves (branches), one entrance of the overpass and two exits of the overpass.

The device for high-speed movement of a passenger train along a single-track railroad includes a track 1, a support for the track 2, a train 3, the carrying wings of cars 4, cars 5, track branches for stopping a train (sleeve) are not shown in the drawing.

Device high-speed movement of a passenger train on a single-track railway operates as follows.

The train, being at the station in one of the branches (branches) 6 of the main road, receives 5 passengers in its wagons. After sealing the doors, the train starts acceleration in one of two (or more) directions of the single-track railway 1. The road has an acceleration section along the length of which the strength of the supports and the web is much greater than on the main high-speed section of the road. The acceleration section (also known as the deceleration or deceleration section) occupies the part necessary for reaching the cruising speed of the train: 350-400 km / h.

After reaching cruising speed, train 3 with passengers travels mostly relying on wings 4 along the track 1 located on the supports 2, until the next slowdown section, after which it gradually stops completely in one of the branches (sleeves) of the track canvases of the road.

On the platform of the station, passengers are disembarked and new ones are landed, after which, having missed the oncoming train (if this is stipulated by the schedule), the rolling stock will continue its movement to the next stopping point.
