  • Patent number: 11518420
    Abstract: A running gear for a rail vehicle includes one or more wheel sets, each having a revolution axis and each being guided by a pair of transversally spaced axle boxes. The running gear further includes a running gear frame, a primary suspension assembly between each of the axle boxes and the running gear frame, and a secondary suspension stage for supporting a vehicle superstructure on the running gear frame. Each primary suspension assembly has at least a main spring assembly having a vertical stiffness and a horizontal stiffness that is identical in a transverse direction of the running gear frame and in a longitudinal direction of the running gear frame perpendicular to the transverse direction. The primary suspension assembly further has an anisotropic interface assembly in series with the main spring assembly between the running gear frame and the axle box.
