Abstract
A driving device for rail vehicles having both a friction drive and a cog gear drive has a common drive shaft placed in the longitudinal direction of the rail vehicle. The drive shaft is provided with driving worms which mesh with worm gears on the driving axles of the friction drive and the cog gear drive. The worms are axially spaced on the drive shaft and engage the respective drive gears of the friction and cog gear drives which are located under the drive motor so as to obtain greater traction force with the friction drive and a more positive meshing of the cog gear with the rack.
Claims21
In a drive device for a rail vehicle having both friction and cog drives and supported on drive wheels, a single drive shaft drivingly connected to a drive motor and disposed in the longitudinal direction of the vehicle, a plurality of friction drive axles for said friction drive and a friction drive gear fixed on each said friction drive axle, a cog drive axle for said cog drive and a cog drive gear fixed on said cog drive axle, said drive wheels mounted only on said friction drive axles, said drive shaft being above and extending over all of said friction and cog drive axles and underneath said drive motor, and a plurality of angular gear drives drivingly connecting said drive shaft with said friction and cog drive gears.
