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 device for force transfer between a chassis frame and a carriage body of a rail vehicle includes a plurality of lemniscate links which are connected to the chassis frame via first joints, a yoke having a middle linking point in which the carriage body can be mounted, wherein the plurality of lemniscate links are connected to the yoke via second joints and form a Z-shaped assembly, where elastically deformable elements are arranged in the in the yoke and the first and second joints, and includes limiting means for receiving impact loads that exceed the operating load so as to limit the maximum deflection of the middle linking point of the yoke in a tractive force direction parallel to a tractive force acting on the chassis frame.

Abstract: A chassis frame for a bogie of a rail vehicle which includes at least one longitudinal member having an upper chord and a lower chord, wherein the longitudinal member has at least one end portion, a central portion, and a transition portion lying between the end portion and the central portion, and the end portion of the longitudinal member is formed as a spring cup for receiving a primary spring, where in order to improve the rigidity curve between the spring cup and the transition portion the lower chord is provided with a curvature in the region of the transition portion, where the curvature is formed such that the imaginary extension of the lower chord and the upper chord itself or the imaginary extension of the upper chord intersect in the end portion.

Abstract: A chassis frame for a rail vehicle having at least two bearing blocks for bearing a torsion bar of a roll stabilizer, where openings are provided in the longitudinal beams of the chassis frame that can receive a torsion bar to prevent an enlargement of the overall height by a torsion bar mounted on the roll stabilizer if the torsion bar is mounted in the bearing blocks.
