Railway Vehicle Wheel with Elastic Rubber Suspension

Abstract

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.
