Abstract

A bogie ( 6 ) comprises a bogie frame ( 7 ). The bogie frame ( 7 ) is mounted on bearings ( 7 b ) via a first spring device ( 7 a ). A wheelset shaft ( 8 ) is mounted in the bearings ( 7 b ). A wheelset drive ( 9 ) concentrically surrounds the wheelset shaft ( 8 ) and acts thereupon. The wheelset drive ( 9 ) is spring-mounted on the bearings ( 7 b ) by means of a second spring device ( 16 ) exclusively associated with the wheelset drive ( 9 ). A two-level clutch ( 15 ) is arranged between the wheelset drive ( 9 ) and the wheelset shaft ( 8 ).

First claim

1 .- 9 . (canceled)

10 . A bogie, comprising:
a bogie frame; a first spring device; bearings configured to support the bogie frame via the first spring device; a wheelset having a wheelset shaft mounted in the bearings; a wheelset drive disposed in concentric surrounding relationship to the wheelset shaft and acting on the wheelset shaft; a second spring device configured to spring-mount the wheelset drive on the bearings, said second spring device being exclusively associated with the wheelset drive; and a two-level clutch arranged between the wheelset drive and the wheelset shaft.

11 . The bogie of claim 10 , wherein the two-level clutch is configured as a double-toothed clutch.

12 . The bogie of claim 10 , wherein the wheelset has wheels arranged at ends of the wheelset shaft in spaced-apart relation from one another, said bearings being arranged between the wheels of the wheelset.

13 . The bogie of claim 10 , wherein the second spring device is configured as a group of buffer elements made of permanently-elastic material.

14 . The bogie of claim 10 , wherein the second spring device is configured as a group of coil springs.

15 . The bogie of claim 10 , further comprising a gearing mechanism arranged between the wheelset drive and the two-level clutch, said wheelset drive acting on the wheelset shaft via the gearing mechanism.

16 . The bogie of claim 10 , wherein the gearing mechanism is configured as a planetary gear train.

17 . The bogie of claim 16 , wherein the wheelset drive has a rotor shaft, said planetary gear train including a hollow-bored sun wheel arranged in fixed rotative engagement on the rotor shaft of the wheelset drive, said wheelset shaft being connected to a planetary carrier of the planetary gear train in fixed rotative engagement via the two-level clutch.

18 . The bogie of claim 10 , further comprising traction current converters arranged on the bogie and configured to connect the wheelset drive to an electrical power supply.

19 . The bogie of claim 18 , further comprising a car body carrier and a third spring device configured to spring-mount the car body carrier on the bogie frame, said traction current converters being arranged on an underside of the car body carrier.
