Abstract (en)
[origin: EP0315621A2] In a switching apparatus for movable parts of a railway point in the diverging region of a point, in particular tongue rails (3), monorail deflection devices or movable stock rails, in which the movable rails (3) can be moved to bear against rigid point parts (1, 2), the movable rails (3) are supported in their bearing position by means of supporting bars (4) which run in the longitudinal direction of the rails and are guided displaceably on the sleepers or baseplates in the longitudinal direction of the rails. In this arrangement, the supporting bars (4) are designed as an actuating member for the switching and comprise thrust supports (7) which interact with thrust supports (10) of the movable rails (3) for the purpose of displacing the rails, at least one of the interacting surfaces of the thrust supports (7, 10) of the rail (3) and/or supporting bar (4) being formed by a wedge surface (8) which merges into a supporting surface (9) which is essentially parallel to the longitudinal direction of the supporting bar (4), which supporting surface (9) interacts with the thrust support (10) of the rail (3) in the bearing position of said rail. As a result, a reliable and exact switching for points, in particular high-speed points having a large radius of curvature, is made possible in a simple manner (Fig. 1). <IMAGE>
