The invention relates to a chassis (100), in particular a low-floor chassis, for a rail vehicle, especially a tram. The chassis (100) comprises at least four wheels (4), each with 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), in particular two torsion bars on one side of the chassis, are connected via a connecting element (21) such that the torques of the torsion bars (20) are opposite in direction, and in particular, the torques essentially cancel each other out.

The invention provides a vehicle-mounted air conditioning system, a vehicle, a control method of the vehicle and a computer readable storage medium. The vehicle-mounted air conditioning system comprises a temperature adjusting module, the temperature adjusting module comprises a frequency converter, a DC-DC unit, a compressor, a ventilator and a condensate fan, the frequency converter supplies power to the compressor, and the DC-DC unit supplies power to the ventilator and / or the condensate fan; the waste exhaust module comprises a waste exhaust fan, the waste exhaust fan is powered by the DC-DC unit of the temperature adjusting module, and a first gas inlet and a first gas outlet of the waste exhaust fan are located in a first position in the compartment and a second position outside the compartment respectively so as to exhaust waste gas in the compartment.

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

The invention relates to a rail vehicle having at least a first carriage (1) and a second carriage (2) which are coupled to one another by means of a carriage coupling device (5), the carriage coupling device (5) having a variable resistance to twisting of the at least first carriage (1) relative to the second carriage (2). According to the invention, a first resistance torque gradient (25) of the carriage coupling device (5) at a first angular position (16) of the at least first carriage (1) relative to the second carriage (2) in a direction of rotation is greater in magnitude than a second resistance torque gradient (26) of the carriage coupling device (5) at a second angular position (17) of the at least first carriage (1) relative to the second carriage (2) in the same direction of rotation, the first angular position (16) being associated with a lesser twisting of the at least first carriage (1) relative to the second carriage (2) than the second angular position (17). In this way, an improved driving behaviour of the rail vehicle is achieved, in particular when entering track curves.

A bogie (100), in particular a low-floor bogie, for a rail vehicle, especially a tram, comprises at least four wheels (4), each having a wheel rotation axis (R). Two opposing wheels (4) that share the same wheel rotation axis (R) can be connected or are connected via a coupling (11) which has a coupling rotation axis (K). The wheel rotation axes (R) and the coupling rotation axis (K) are different, in particular parallel. This is an active coupling (11).
