Abstract
A chassis frame for a rail vehicle includes a plurality of longitudinal beams formed as I-beams, wherein each longitudinal beam includes a longitudinal beam top flange, a longitudinal beam bottom flange and a web, a box-shaped transverse beam interconnecting the plurality of longitudinal beams, each longitudinal beam having a central section in which the longitudinal beam is connected to the transverse beam, where each longitudinal beam forms at least one wheelset guide bushing for connection to a wheelset guide, where a stiffening rib is arranged in each longitudinal beam on both sides of the web, and where the stiffening rib extends outward from the web in a transverse direction on both sides of the web and is configured such that the force flow from the wheelset guide bushing is conducted into the transverse beam such that the shear stiffness and transverse stiffness of the chassis frame is increased.
