Abstract
Provided is a grooved rail for rail vehicles having flanged wheels, the grooved rail including a rail head provided with a running rail, a flange groove, and a counterrail, in addition to a rail web, a rail base, and lateral rail chambers extending between the rail head and the rail base. The running rail includes an asymmetrically-arranged vehicle-guiding flange, extending towards the flange groove, the asymmetrically-arranged flange formed in such a way that the width part of the rail base, on the side of the running rail, is larger than the width part on the side of the counterrail by a factor of at least 1.2. When the depth of the flange groove is >20 mm, the flange has a flange inclination of >78° with respect to an essentially horizontal axis of the rail web.

A grooved rail for rail vehicles provided with flange wheels, said grooved rail comprising a rail head provided with a running rail, a flange groove, a counterrail, a rail web, a rail base and lateral rail chambers extending between the rail head and the rail base, wherein the running rail comprises a vehicle guiding flange extending towards the flange groove, said flange having a flange inclination of <78° with respect to an essentially horizontal axis of the rail head when depth of the flange groove is >20 mm, and total width of the rail base is asymmetrically arranged with respect to the rail head with reference to a vertical central axis of the rail web whereby the total width of the rail base consists of a first part on a first side of the vertical axis including at least a major portion of the running rail and a second portion on a second side of the vertical axis including the counterrail, the first portion being larger at least by a factor 1.2 than the second portion and width of the running rail being from 55 to 65% of total width of the rail head and further wherein the ratio of total height of the grooved rail to the total width of the rail head is from 1:1.2 to 1:1.4.
A grooved rail for flange-wheeled rail vehicles, the grooved rail comprising a rail head provided with a running rail whose width is 55 to 65% of the total width of the rail head, a flange groove, a counterrail, a rail web, a rail base and lateral rail chambers extending between the rail head and the rail base, wherein
- the running rail comprises a vehicle guiding flange extending towards the flange groove, the guiding flange having a flange inclination of <78° with respect to an essentially horizontal axis of the rail head when depth of the flange groove is >20 mm, total width of the rail base being asymmetrically arranged with reference to a vertical central axis of the rail web, the total width of the rail base consisting of a first part on a first side of the vertical axis and a second portion on a second side of the vertical axis including the counterrail, the first portion being larger than the second portion by a factor of at least 1.2;
- and further wherein
- the ratio of total height of the grooved rail to the total width of the rail head is from 1:1.2 to 1:1.4,
- the total height of the grooved rail to the total width of the rail base is from 1:1.5 to 1:1.8,
- the ratio of the total width of the rail head to the total width of the rail base is from 1:1.2 to 1:1.4, and
- the ratio of the thickness of the rail web to the total width of the rail base is from 1:4 to 1:9.
