Embodiment Construction

[0035] figure 1 A rail switch according to the invention is shown, comprising two tongue rails 1 and two basic guide rails 2 . The tongue rails 1 are each assigned to a base rail 2 . Three adjustment planes 3a, 3b and 3c are arranged along the switch, in which adjustment devices (not shown) and final position checking devices (not shown) are arranged for selectively guiding the tongue rail 1 towards the substantially The rail 2 is shifted to or away from the basic rail 2. In the resting state, the tongue rail 1 rests on the base rail 2 in a first longitudinal section extending from the first adjustment plane 3 a to the third adjustment plane 3 c. Furthermore, 4 designates the clamping region of the tongue rail 1 , which is located in the second longitudinal section of the tongue rail, which extends from the third adjustment plane 3 c to the clamping region 4 . The tongue rail 1 has a cross section that varies along the longitudinal extent of the tongue rail, wherein in part...

Abstract

The invention relates to a tongue rail (1) for use in points, comprising a rail head (5), a rail web (6) and a rail base (7), wherein the tongue rail (1) has a first long section provided for abuttinga stock rail (2) and a second, long section lying outside the abutting region, wherein the tongue rail (1) has in the second long section a basic cross-section profile, wherein in the second long section a vertically running central axis is defined in cross-section through the middle of the rail head (5), and a first section (10) of the rail base (7) is arranged on a first side of the central axis and a second section (11) of the rail base (7) is arranged on a second side of the central axis opposite the first side, wherein the width of the first section (10) of the rail base (7) is greater in cross-section than the width of the second section (11) of the rail base (7), and wherein the cross-section of the tongue rail (1) has, at at least one point along the longitudinal extent of the rail, a ratio between the vertical area moment of inertia I y and the horizontal area moment of inertia I x of more than 0.5, preferably more than 0.6, particularly preferably more than 0.7.

Description

technical field [0001] The invention relates to a rail tongue for use in rail switches, the tongue rail comprising a rail head, a rail web and a rail bearing, wherein the tongue rail has a feature that is provided for abutting against a basic rail (Backenschiene) A first longitudinal section and a second longitudinal section located outside the contact region, wherein the tongue rail has a cross-sectional basic profile in the second longitudinal section and preferably the basic profile is machined in the first longitudinal section To match the width for the construction extension in particular in the rail head, wherein in the second longitudinal section a vertically extending central axis is defined in a cross-section passing through the center of the rail head, and the first zone of the rail support The segments are arranged on a first side of the central axis and the second section of the track support is arranged on a second side of the central axis opposite the first side,...
