Abstract

Device for supporting rails in a railroad track for rail-borne vehicles includes a support plate (3) positioned on a support bed (6) with profiled surfaces on the support plate and the support bed having upwardly extending flanks (4a, 7a, 5a, 8a) forming different angles. The flanks extend in the long direction of the railroad track. Elastic elements (9a, 9b, 9c, 9d) are disposed between the flanks (4a, 7a, 5a, 8a) of the support plate in the support bed, whereby the support plate can pivot relative to the support bed when a load (P.sub.H, P.sub.V) acts on the rails. The support plate pivots toward the center of the railroad track. As a result, the rail head (1d) of the rail attached to the support plate (3) is essentially offset vertically during the pivoting action, so that the rail gauge of the railroad track remains unchanged.
