Embodiment Construction

[0035] figure 1 A rail switch according to the invention is shown which comprises two tongue rails 1 and two basic rails 2 . The tongue-shaped rails 1 are each assigned to a basic rail 2 . Three adjustment planes 3a, 3b and 3c are provided along the switch, in which adjustment means (not shown) and end position checking means (not shown) are arranged for selectively orienting the tongue track 1 towards the base The rail 2 is shifted or moved away from the base rail 2. In the abutting state, the tongue rail 1 rests on the basic rail 2 in a first longitudinal section extending from the first adjustment plane 3a to the third adjustment plane 3c. Furthermore, 4 is used to designate the clamping region of the tongue rail 1 , which is located in a second longitudinal section of the tongue rail, which extends from the third adjustment plane 3 c as far as the clamping region 4 . The tongue-shaped rail 1 has a cross-section that varies along the longitudinal extent of the tongue-sha...

Abstract

The invention relates to a tongue track (1) for use in a track switch, comprising a track head (5), a track web (6) and a track support (7), wherein the tongue track (1) has a set of A first longitudinal section for contacting the base rail (2) and a second longitudinal section outside the contact area, wherein the tongue-shaped rail (1) in the second longitudinal section has a substantially transverse cross-section Profile wherein a vertically extending central axis is defined in the second longitudinal section in a cross section through the centre of the rail head ( 5 ) and the first section ( 10 ) of the rail support ( 7 ) is arranged in the centre On the first side of the axis and the second section ( 11 ) of the rail support ( 7 ) is arranged on the second side of the central axis opposite the first side, wherein the first region of the rail support ( 7 ) The width of the segment (10) is greater in cross-section than the width of the second section (11) of the rail support (7), and wherein the cross-section of the tongue-shaped rail (1) is at least one along the longitudinal extent of the rail The site has a moment of inertia I in the vertical area y and the horizontal area moment of inertia I x The ratio between is greater than 0.5, particularly preferably greater than 0.6, particularly preferably greater than 0.7.

Description

technical field [0001] The invention relates to a tongue-shaped rail for use in a rail switch, which tongue-shaped rail comprises a rail head, a rail web and a rail support, wherein the tongue-shaped rail has an arrangement for contacting a base rail. and a second longitudinal section outside the contact area, wherein the tongue-shaped rail has a cross-sectional basic contour in the second longitudinal section and preferably the basic contour is machined in the first longitudinal section To be adapted to the width of the extension, in particular in the rail head, wherein in the second longitudinal section a vertically extending central axis is defined in the cross section through the centre of the rail head, and the first region of the rail support The segment is arranged on a first side of the central axis and the second section of the rail support is arranged on a second side of the central axis opposite the first side, wherein the width of the first section of the rail supp...
