摘要： A stress-homogenized track wheel with a wheel disk (3) which connects the wheel hub (1) and wheel rim (2) and decreases in thickness from the hub (1) towards the rim (2), the disk's outer surfaces merging via three-center curves as radial generatrices tangentially with the adjacent outer surfaces of the hub (1) and rim (2) is shown. In order to suppress stress peaks and reduce the stress across the radial width of the wheel disk, the two outer surfaces of the wheel disk (3) are defined in the radial central area (1) geometrically by radial straight generatrices (Z3*,Z3**) which intersect in the area between the three-center curves on the wheel rim (2).

摘要： A rubber member for rubber-elastic rail wheels which in the expanded state has an oval opening for receiving a flexible current bridge. When the rubber member is incorporated in the rail wheel, the opening assumes a substantially circular cross-section under prestressing.

摘要： 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.

摘要： A rubber-sprung rail vehicle wheel which is designed in particular, but not exclusively, for rail vehicles with a low design height is described. In this rail vehicle wheel, the wheel tire (2) is connected to the wheel rim (3) by way of a rubber insert that is formed by two flat rings (11, 12) that are arranged so as to be essentially vertical in relation to the wheel axle. The rings (11, 12) are held, under very considerable axial prestress, between an inner circumferential middle web (5) of the wheel tire (2) and two outer flanges (6, 8) of the wheel rim (3). At least one of the flanges (8) is seated on the wheel rim (3) with an interference fit (9) that is designed as a conical press fit. The interference fit (9) is designed such that the cone of the flange (8) in the stress-free state has a lesser conicity than does the cone of the wheel rim (3), and in the pressed-on state rests on the entire surface against the cone of the wheel rim (3), as far as possible at an even surface pressure across the entire width of the interference fit (9). This provides a secure hold for the flange (8). There is no need to provide additional screw bolts (10) in the region of the rings (11, 12) of the rubber insert, so that the space between the web (5) and the flanges (6, 8) can be utilised entirely for the rubber insert.
