Abstract: A chassis (100), in particular a low-floor chassis, for a rail vehicle, in particular for a tram-way. The chassis (100) comprises at least four wheels (4) each having a wheel bearing, at least two wheel axles for suspending the wheels (4), a chassis frame (1) and a primary suspension for suspending the wheels (4) relative to the chassis frame (1). The primary suspension has at least four torsion bars (20). Two torsion bars (20) each, in particular two torsion bars on one side of the chassis, are connected via a connecting element (21) in such a way that the torque of the torsion bars (20) oppose each other, in particular the torques essentially cancel each other out.

Abstract: A bogie (100) for a rail vehicle. The bogie (100) comprises a frame (10) that is mounted on one or more wheel axles (20). The bogie (100) comprises at least one support surface for a vehicle body (40). At least one liftable surface on the bogie (100) is designed in such a way that its vertical distance, from the support surface, can be modified by a lifting element (50).

Abstract: The rail vehicle has at least one truck (1) with two wheelset units (12, 12') which are hingedly connected to one another via a coupling arrangement. This truck (1) is formed as a frameless support arrangement and the vehicle body (17) is supported on spring elements (10) and has at least one guide device or at least one pendulum (11) between the truck (1) and the vehicle body (17). The design is greatly simplified by the omission of the complicated bogie frame and is thus light and compact. The radially adjustable wheelset units (12, 12') can moreover be arranged with a small spacing from one another. The frameless truck (1) is accordingly particularly well suited for rail vehicles on rail networks which have narrow turning radii.
