Drive device for driving rail vehicle, has transmission units provided for stabilization of output speed, where units are designed as one free-wheel between drive, output and gears and as another free-wheel between drive and output

摘要

The device has transmission units for stabilization of an output speed. The transmission units are designed one free-wheel (7) between a drive (5), a rotary direction-constant output (3) and transmission gears (8), and as another free-wheel (9) between the drive and the output. The former free-wheel is drive-effective in one drive stage and the latter free-wheel is drive-effective in another drive stage. The transmission gears are designed as planetary gears. The drive includes a drive shaft designed as a hollow shaft (6). The output includes an output shaft arranged in the hollow shaft.
