Abstract
A rail vehicle undercarriage comprises a load bearing implement 1 in the form of the bogie frame of a two-axle bogie, wherein the load bearing implement 1 is supported on two wheel pairs 4, 4; 4, 4 by means of spring elements 2. One respective steering rod 9 that extends in the running direction of the wheels is provided per wheel 4, wherein said steering rods are coupled to the wheel carrier 3 adjacent to the corresponding wheel 4 with one end and to the load bearing implement with their other end in coupling points 8, 10. The wheel pairs can be turned relative to the load bearing Implement. In order to achieve a turning movement of the wheel pairs towards a curve-radial adjustment which depends on the curve radius of the currently used track, the respective steering rods 9 are directly coupled to the load bearing implement 1 in coupling points 10. In addition, the coupling points 10 of the steering rods 9 of at least one wheel pair 4, 4 are, referred to the plane defined by the contact points 6 between the wheels 4 and the rails 7, situated above the coupling points 8 of the steering rods 9 on the corresponding wheel carrier 3 when the steering rods 9 point toward the central region between two wheel pairs in the running direction of the wheels.
