Patent ID: 7066095

Claim:
A rail vehicle undercarriage with at least one load bearing implement that is supported by means of at least one spring element on at least one of two associated wheel pairs that are arranged behind one another in the running direction, and with one steering rod per wheel which extends approximately in the running direction of the respective wheel, one end of each respective steering rod being connected to a corresponding wheel carrier at a coupling point adjacent to the wheel and the other end of each respective steering rod being coupled to the load bearing implement, the wheel pairs being turnable relative to the load bearing implement, wherein the respective steering rods are directly coupled to the load bearing implement at coupling points, which are either a) above the coupling points of the steering rods on the respective wheel carrier if the steering rods are situated within an intermediate space between the associated wheel pairs in the running direction of the wheels or b) underneath the coupling points of the steering rods on the respective wheel carrier if the steering rods are situated outside the intermediate space between the associated wheel pairs in the running direction of the wheels, in order to achieve centrifugal force induced, automatic, curve radial adjustment of the wheel pairs on negotiating curves.
