Abstract (en)
[origin: WO2012113422A1] The invention relates to a gearbox for the drive train of a rail vehicle, comprising an input for connecting a drive motor of the rail vehicle; comprising an output for connecting driven wheels of the rail vehicle; and comprising a driving connection between the input and the output that forms a gear ratio between (5) and (10). The invention is characterized in that the gear ratio is formed by two gear-ratio stages connected one after the other in the driving connection, of which the first gear-ratio stage has a gear ratio between (1) and (2) and the second gear-ratio stage, which is arranged after the first gear-ratio stage in the drive-power flow from the input to the output, has a gear ratio greater than twice the first gear-ratio stage.
