Abstract

FIELD: transport.

SUBSTANCE: proposed car comprises trucks 1 with wheel pairs 2, frame 3 with coupling elements 4, all-metal body 5 with platform attached thereto and representing wing that exhibits lift 7 in motion in air medium. Said wing is secured above the body, its position can be varied in height. Wing has a mounting seat for it to be fitted in central strut that features ellipse shape cross section with central bore. Note here that said wing is rigidly jointed to vertical shaft passed through strut hole to go up-and-down and turn through 180°.

EFFECT: increased track service life, reduced wear of wheel pairs and rails, fuel and power savings.

Description

The invention relates to railway transport, in particular to high-speed passenger and freight trains.

A well-known railway carriage containing biaxial / triaxial bogies with wheelsets, a frame with coupling elements, an all-metal body with a platform fixed to it [1].

The objective of the invention is to reduce the pressure of a railway carriage moving at high speed on a railway (rail) track.

The technical result is achieved by the fact that in a railway carriage containing bogies with wheelsets, coupling elements, a body with a platform fixed to it in the form of a wing having lift when moving in air, the wing has a landing seat for landing on a central rack having cross-sectional shape of an ellipse with a hole in the center, and the wing is rigidly connected to a vertical shaft passed into the hole of the rack, and is made to rotate 180 °. Aerodynamic ribs are made on the sides of the wing.

Figure 1 shows a railroad car with a wing fixed above the body, an end view, figure 2 is a view of figure 1 by A, figure 3 shows a wing with aerodynamic fins; on Fig 4 shows a side view of a fragment of the upper part of the body with a wing that can rotate 180 °; figure 5 shows a cross section BB of the rack depicted in figure 4.

A railway carriage, for example, of a passenger train with a locomotive providing high speeds (more than 100 km / h) of movement along a railway (rail) track, contains biaxial trolleys 1 with wheel pairs 2, a frame 3 with coupling elements 4, an all-metal body 5 with a sloping roof 6, windows, doors for entry / exit passengers. At least one wing 7 is installed above the roof of the body, having lift when moving in air. On the sides of the wing can be made aerodynamic ribs 8. The wing is installed above the roof of the body on the Central rack 9 with the ability to rotate 180 °. The central pillar has an elliptical cross-sectional shape with a hole 10 in its center, and the wing has an ellipse-shaped landing seat 11 with a vertically mounted shaft 12 rigidly attached to the wing.

In the cavity 13 of the body (under the roof) are mechanisms (not shown) for raising / lowering and turning the shaft. For raising / lowering the wing shaft, for example, a membrane air motor, cam, lever mechanisms can be used. To rotate the shaft, a lamellar, figure-and-slide rotary pneumatic motor, as well as a worm, rack and pinion piston mechanism, can be used. The mechanisms for raising / lowering and turning the wing shaft can communicate with a system (not shown) for the distribution of compressed air. It is possible to lift the wing above the central pillar, rotate it 180 °, lower it (landing by a nest on the central pillar), followed by fixing the shaft, manually.

A railroad car is made as follows.

A frame 3 is made with elements 4 of a coupler, biaxial trolleys 1 with wheelsets 2. An all-metal body 5 with windows and doors for entry / exit of passengers is mounted on the frame. The wings 7 are made with aerodynamic fins 8. The wings intended for installation over the roof 6 of the body on the central struts 9 are made with a seat socket 11 and a shaft 12. A shaft rigidly connected to the wing is passed into the hole 10, while the wing seat is put on the upper part central rack. The end of the shaft extending into the cavity 13 of the body is connected to the mechanisms for raising / lowering and turning the wing of 180 ° fixed under the roof of the body. Raising / lowering and turning the shaft can be carried out manually or by supplying compressed air to the actuators. Then the shaft is fixed so that when the carriage moves, the wing of the landing seat is pressed against the central pillar.

A railway carriage equipped with wings mounted on central racks allows it to be coupled with a locomotive and other cars from any of its ends. To do this, it is enough to make the necessary rearrangement of the wing from one position to another at an angle of 180 °.

When a railway carriage moves, the flow of oncoming air, acting on the wings attached to the body, creates a lifting force, as a result of which the pressure of the wheels on the railway (rail) track decreases. This increases the resource (duration of operation, safety of the canvas) of the railway track, reduces wear on wheelsets, reduces the cost of fuel / electricity by a locomotive.
