WHEEL, PARTICULARLY RAIL WHEEL FOR RAIL VEHICLES

摘要

In order to obtain a wheel (1), particularly a rail wheel for rail vehicles, having a single-part or multi-part wheel body (3), which comprises a wheel hub (5) and a wheel rim or tire (4), and having at least one three-dimensional connecting element (8, 9, 15), wherein said wheel effects reduced sound radiation, a reinforcement of the wheel is proposed such that one or more dominant system natural frequencies of the wheel or the wheel set, formed by the two wheels and the wheel set shaft, are displaced outside of the exciter frequency range resulting from the wheel-rail contact. For this purpose, the connecting element (8) forms a rigid open or closed structure together with the wheel body (3), or the connecting element is a wheel web (15) connected to the wheel hub and wheel rim or tire (4) in a positive, non-positive and/or firmly bonded way, and at least on disc-shaped element (8, 9) disposed parallel or diagonal to and at a distance from the wheel web (15) is additionally connected to the wheel hub and tire in a positive, non-positive and/or firmly bonded way, or a known wheel web (15) is replaced by two disc-shaped connecting elements (8), which are single-part or multi-part reinforced bodies (8, 9) that are spaced from each other and additionally connected to the wheel hub (5) and wheel rim or tire (4) in a positive, non-positive and/or firmly bonded way, or a known wheel web (15) is replaced by two disc-shaped connecting elements (8), which are single-part or multi-part reinforced bodies (8, 9) that are spaced from each other and are additionally connected to wheel hub (5) and wheel rim or tire (4) in a positive, non-positive and/or firmly bonded way.
