Rail vehicles with Top speeds over 160 km / h according to the state the technology of power cars and locomotives with higher ones Services (over 4000 kW) but only fully sprung drive devices. Freight trains with low speed limits and high tractive effort are often with a simple Tatzlagerantrieb without a clutch equipped, the traction motor robust and heavy trained is over and over the transmission is supported on the wheelset shaft via so-called Tatzlager. at higher Speeds impact which impacts be transmitted to the wheelset shafts through bumps on the rails via the wheels, unfavorable to this drive device.

• - with an electric traction motor
• - a gearbox,
• - One arranged between the traction motor and the transmission clutch having coupling components, and
• - Haltemitteln fully cushioned the traction motor, but keep the drive device in total teilabgefedert on the rail vehicle, wherein

the transmission is supported on the drive motor and the support is such that relative movements of the coupling components are reduced in coupling levels of the clutch, solved.

The Invention provides that between the transmission and the traction motor a clutch which controls the rotation of a motor shaft of the traction motor on the gear transmits, arranged is. The gearbox is supported on the traction motor so that relative movements reduced by coupling components in coupling levels of the coupling are to realize a simple and compact design of the coupling to be able to This is based on the knowledge that the fully sprung traction motor at speeds above 160 km / h is then sufficiently secured from shocks when on the traction motor only partially abgefe dertes or unsprung Gearbox supported. this makes possible a lightweight version the drive motor opposite the drive motor in the Tatzlagerantrieb.
