ABSTRACT:
A hydrodynamic 2-speed turbine drive, in particular, a turbine drive for application in under-floor or low-floor drive systems on rail vehicles, with two hydrodynamic components for the formation of two tractive-work circuits for two different speed ranges. A first hydrodynamic component is in the form of a hydrodynamic speed/torque converter and a second hydrodynamic component is in the form of a hydrodynamic clutch. The converter and the clutch are arranged parallel to each other and with no, or very little, offset between drive input shaft and drive output shaft.
