A rubber-sprung wheel for rail vehicles includes a wheel tire which is connected to a wheel rim by a rubber insert that is formed by two flat rings that are arranged so as to be essentially vertical in relation to a wheel axle. The two flat rings are held, under considerable axial prestress, between an inner circumferential middle web of the wheel tire and two outer flanges of the wheel rim. At least one of the flanges is seated on the wheel rim with an interference fit that is designed as a conical press fit, such that a cone of the flange in a stress-free state has a lesser conicity than does a cone of the wheel rim, and in a pressed-on state rests on an entire surface against the cone of the wheel rim, at an even surface pressure across an entire width of the interference fit.
A rail vehicle wheel in which a wheel tire is connected to a wheel rim by way of a rubber insert that is formed by two coplanar perforation-free rings arranged to be inclined or vertical in relation to a wheel axle, wherein the two coplanar perforation-free rings are exclusively held, under axial prestress, between supporting surfaces arranged to be inclined or vertical in relation to the wheel axle and that are formed by a circumferential inner middle web of the wheel tire and two outer flanges of the wheel rim,
