Rail vehicle

[0015] figure 1 The 1 marked in is the electric motor compartment of the rail vehicle 2. For the sake of clarity, only its traction intermediate circuit 3 and its converter 4 are shown for the motor car 1 . The voltage of the traction intermediate circuit, typically 3 kV DC, is converted by means of the converter 4 into a DC voltage Uz on the train bus 5 , which runs through all the cars of the rail vehicle 2 and is at a voltage level of 440 V DC. The motor car 1 is equipped with an electric motor, not shown, which is fed directly from the intermediate traction circuit. The small circles on the chassis of the motor car 1 shall represent the wheels or axles 6 driven by traction motors not shown.

[0016] In the illustrated rail vehicle 2 there is a first non-driven carriage 7 and a further non-driven carriage 8 on both sides of the electric motor carriage 1 . The two carriages 7 or 8 are here embodied identically in the relevant relation, so that the following description can r
