Abstract

Rail vehicle for operation on rail systems with a ballast superstructure, which has at least two individual wagons (1, 2) connected by a coupling (3), between which there is a spacing (4), characterized in that the individual wagons (1, 2) a plate-shaped element (6) projecting horizontally into the distance (4) in the form of a deflector plate for reducing currents induced in the track bed is attached at the level of their sub-floor (5).

Description

The invention relates to a rail vehicle for driving on rail systems with ballast superstructure, which has at least two individual cars connected by a coupling, between which there is a distance.

When driving such vehicles, a problem occurs which is referred to by those skilled in the art as ballast, gravel, ballast or ballast. The problem of gravel flight is especially current on trains that operate at speeds above 200 km / h. This problem is explained in more detail below: A common possibility of the threshold bedding is the ballast track. In classical ballast superstructure, individual ballast stones can be thrown out of the track bed and thrown up, in particular by trains moving overhead. These gravel stones are hit by the underfloor area of the vehicle or, conversely, hit the vehicle. Possible consequences are damage to the vehicle, especially to its underfloor area and system components arranged there, as well as damage to the environment caused by flying ballast stones.

The frequency of launching ballast beneath a moving rail vehicle is determined by the amount of longitudinal flow induced by the vehicle in the track bed. The lower this flow, the lower the frequency of thrown up ballast stones. Therefore, it is the object of the present invention to reduce as much as possible the amount of the induced flow in a rail vehicle of the generic type.

This object is achieved by the features mentioned in the characterizing part of patent claim 1. By attached to the individual cars at the level of their subsoil and horizontally projecting into the space between the individual cars plate-shaped elements, a horizontal aerodynamic closure of the gap existing due to the distance is achieved, which significantly reduces the currents induced in the track bed. The plate-shaped elements derive the falling in the transition region of the individual cars flow and can therefore be referred to as deflector plates or deflectors.

Advantageous embodiments of the invention are specified in the subclaims.

An embodiment of the invention is illustrated in principle in the drawing and will be described in more detail below. Show it

1 a rail vehicle in the area of the transition of two single wagons 1 and 2 , in side view,

2 the top view too 1 .

3 a modified embodiment, also in plan view,

4 a design option for a deflector element 6 in perspective view.

The rail vehicle in the form of a train is intended for driving on rail systems with ballast track. Such, here altogether with 7 designated rail system usually consists of the actual rails, the thresholds and a variety of ballast stones. The single cars 1 and 2 of the train, which of course may include more single wagons, are through a clutch 3 connected, being between the single cars 1 and 2 a distance 4 consists. To the single car 1 and 2 is at the level of your subsoil 5 within the vehicle boundary line in each case a plate-shaped element 6 attached These elements 6 protrude horizontally into the distance 4 into it.

The plate-shaped elements 6 are preferably as wide as the single cars 1 and 2 and designed as large as the necessary clearance of the individual cars 1 and 2 especially for bending movements when cornering and transverse movements by the transverse suspension permits. Accordingly, the plate-shaped elements 6 in the 2 having shown semicircular boundary contour. According to 3 there is a possibility of the plate-shaped elements 6 with side recesses 6a for cables or hoses running between the single wagons. The plate-shaped elements 6 However, they may also have a boundary contour different from the semicircle.

The end 4 as an item visible plate-shaped element 6 is from a sheet metal 6b and associated with its top angle profiles 6c educated. The angle profiles 6c are with recesses 6d provided, which prevent the accumulation of dirt and moisture.
