2results about "Tramway vehicles" patented technology

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.

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).
