Abstract:
1. A hydrodynamic 2-speed hydraulic drive for application in under-floor drive systems on rail vehicles with a low-floor part, comprising: a drive input shaft ( two hydrodynamic components for formation of two tractive-work circuits for two different speed ranges including a first hydrodynamic component in a form of a hydrodynamic speed-torque converter ( a step-up gear set coupled with the drive input shaft ( the hydrodynamic speed-torque converter ( the hydrodynamic speed-torque converter ( the hydrodynamic speed-torque converter ( the hydrodynamic clutch ( a hydrodynamic brake mechanism in a form of a hydrodynamic retarder ( the hydrodynamic retarder ( the hydrodynamic clutch ( the secondary shafts ( the hydrodynamic retarder in coaxial arrangement to the hydrodynamic speed-torque converter.
