Abstract: A chassis frame for a rail vehicle which includes at least one drive unit fastened to the chassis frame via at least one elongated fastener, wherein the at least one fastener is arranged transversely with respect to the direction of travel and protrudes into the chassis frame or is guided through brackets which are fixedly connected to the chassis frame and protrudes into a space above or below the chassis frame in order to reduce the weight for the bearing of the drive unit and to facilitate mounting of the drive unit.

Abstract: A longitudinal support and a transverse support for a chassis frame of a rail vehicle, wherein the longitudinal support includes a first box-shaped connection portion having a sectionally straight first circumferential edge for connection to the transverse support, where the transverse support has a second box-shaped connection portion having a sectionally straight second circumferential edge for connection to the longitudinal support within a transverse direction of the chassis frame, respectively on the end side, and where the first and second circumferential edges are each configured as four first and second connection edges to achieve a reduction of the weight of the longitudinal support and of the transverse support, and to lower the twisting rigidity of the chassis frame, where the connection edges are separated from each other by first and second recesses.

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.

Abstract: A bogie frame for a rail vehicle that includes two longitudinal supports formed as open and closed hollow profiles, and at least one transverse support, wherein the hollow profile of the longitudinal support is formed by wall elements having a defined thickness, wherein in order to reduce the weight of bogie frames in comparison to conventional bogies frames and to save on production costs, the longitudinal supports, in the region at which the at least one transverse support engages, is respectively provided in a wall element with at least one area having a reduced thickness.

Abstract: A brake carrier for bogies of rail vehicles has an open cross-section with flexible torsion. A connection to two longitudinal members of the bogie is designed as a rigid non-articulated connection and a braking device is fixed to the brake carrier in such a way that a line of action of braking forces runs through the shear centre that lies outside the cross-section of the brake carrier.

Abstract: A primary spring for chassis of rail vehicles is provided. The spring is designed as a substantially rectangular layered spring that is fitted into a bearing housing.
