Patent number: 10099707Abstract: A bogie (6) comprises a bogie frame (7). The bogie frame (7) is mounted on bearings (7b) via a first spring device (7a). A wheelset shaft (8) is mounted in the bearings (7b). A wheelset drive (9) concentrically surrounds the wheelset shaft (8) and acts thereupon. The wheelset drive (9) is spring-mounted on the bearings (7b) 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).Type: GrantFiled: December 10, 2014Date of Patent: October 16, 2018Assignee: Siemens AktiengesellschaftInventors: Olaf Koerner, Hartmut Frank, Thomas Liebig, Thomas Oehler, Bernd Pfannschmidt, Tobias Stärz

Patent number: 4510395Abstract: A longitudinal double-axle drive for an electric, track-bound, self-propelled vehicle is disclosed in which the electric propulsion motor is disposed longitudinally between two driving axles of the vehicle. The motor drives both driving axles via a respective angle transmission. In order to provide flexiblity for operating under different conditions, the electric propulsion motor is a double motor with two electrically independent rotors of equal length and a common stator comprised of two separate stator lamination stacks and a continuous stator winding. The side of each rotor facing its associated transmission is supported by an overhung arrangement from the transmission housing. Thereby, the two driving axles can rotate at different speeds without compulsion forces being generated.Type: GrantFiled: September 30, 1982Date of Patent: April 9, 1985Assignee: Siemens AktiengesellschaftInventor: Christian Sohrt

Patent number: 4461218Abstract: In a propulsion unit for the driven axles of an electrically-powered rail vehicle, the torque of an electric propulsion motor is transmitted to the respective driven axle by way of a torque transmitting mechanism including gears and couplings. A common housing in the form of a hollow beam is used to enclose the propulsion motor, a bearing system, and a transmission. Cut-outs are provided in the sides of the housing to allow space for the driven axles. In order to increase the flexural and torsional stiffness of the propulsion unit, the hollow beam includes an annular end surface through which the propulsion motor and torque transmitting apparatus are inserted. The hollow beam not only forms a common housing or the propulsion components, but is a very stiff support element that reduces vibration and improves the running behavior of the propulsion unit.Type: GrantFiled: August 5, 1981Date of Patent: July 24, 1984Assignee: Siemens AktiengesellschaftInventors: Jurgen Kuhlow, Christian Sohrt

Patent number: 4130065Abstract: A drive for a railway track-bound propulsion vehicle includes a traction motor with output shafts on both sides. The motor is longitudinally arranged between two driving axles of a track-bound propulsion vehicle and is designed without a housing. In addition, the drive pinions are arranged directly on the rotor shaft which is supported in bearings in the transmission housing which also supports the stator of the traction motor. To take up the thermal expansion due to the different temperature rise of the stator and the rotor, at least one centering coupling which permits longitudinal displacement is provided in the train of the rotor shaft.Type: GrantFiled: March 24, 1976Date of Patent: December 19, 1978Assignee: Siemens AktiengesellschaftInventors: Roman Susdorf, Ulrich Schuler, Heinz Engelmann
