Provided is a rail car that is capable of efficiently transmitting vibrational forces that have been transmitted from a bogie via a yaw damper and a yaw damper support to an underframe to a rail car shell, and that is of a simple structure, sufficient mechanical strength, and light weight for reducing the amount of heat applied to perform welding and for allowing a nondestructive inspection to be performed with ease. The rail car includes a rail car shell, a bogie that supports the rail car shell, a yaw damper having an end connected to the bogie, and a yaw damper support to which another end of the yaw damper is connected. The rail car shell includes an underframe including a floor assembly providing a floor and a bolster beam joined to the floor assembly, and a pair of side structures erected at both transverse ends of the underframe. In this rail car, the yaw damper support is fixed to a transverse end of the bolster beam.

Disclosed is a bogie for a rail vehicle. One embodiment of a rail vehicle includes a bogie frame and at least four wheels arranged at the bogie frame. The bogie frame has a first and second frame parts, each frame part including a longitudinal beam and a cross beam. Each cross beam can be fixedly attached at the first end to the respective longitudinal beam. Each cross beam includes a pin at the second end. The longitudinal beam of the first frame part includes a receptacle for the pin of the second frame part and the longitudinal beam of the second frame part has a receptacle for the pin of the first frame part. The bogie can include one or more at bushing that includes elastomeric material, such as an elastomeric flange bushing, where the bushing is fixed to each cross beam or to the pin of the cross beam.

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.

The electric vehicle can include: a payload interface, a payload suspension, a chassis, a set of bumpers, a sensor suite, a controller, a chassis suspension, and an electric powertrain. The electric vehicle 100 can optionally include a payload adapter, a power source, a cooling subsystem, and/or any other suitable components. The electric vehicle functions to structurally support a payload, such as a cargo container (e.g., intermodal container, ISO container, etc.), and/or to facilitate transportation of a payload via railway infrastructure.

The present disclosure relates to a computer-implemented method for determining a real time steering angle (58) for a railway bogie (1) and to a control device (40) which is configured to perform the method, the method comprising: deter-mining by a sensor assembly at least one lateral real time sensor signal (38), which is characteristic for a lateral position of a tread of at least one wheel of the railway bogie (1) with respect to a railway track, determining, by means of a positioning algorithm (47), a real time position and/or orientation of the railway bogie (1) with respect to the railway track (31), using the received at least one lateral real time sensor signal (38) and determining the real time steering angle (58) for steering of the railway bogie (1), using the determined real time position and/or orientation of the railway bogie (1).

An active adjustment method of connecting rod length and an active adjustable connecting rod device, liquid medium is introduced into a first liquid cavity or a second liquid cavity, so that the piston is hydraulically driven to move, thereby realizing contraction of the connecting rod. The control system controls opening sizes and switching frequencies of the valves, to control extension or contraction speed of the connecting rod. To realize this method, design an active adjustable connecting rod device, which comprises two cylinders, a cylinder is connected with a rod body and a gas source by pipelines.
