Abstract: A driving mechanism for operating a shaping die to join stacked plates by a deep-drawing and swaging operation is implemented as an electric drive, such as a linear motor or a rotary motor, which is operatively connected to the shaping die.

Abstract: A rail vehicle undercarriage comprises a load bearing implement 1 in the form of the bogie frame of a two-axle bogie, wherein the load bearing implement 1 is supported on two wheel pairs 4, 4; 4, 4 by means of spring elements 2. One respective steering rod 9 that extends in the running direction of the wheels is provided per wheel 4, wherein said steering rods are coupled to the wheel carrier 3 adjacent to the corresponding wheel 4 with one end and to the load bearing implement with their other end in coupling points 8, 10. The wheel pairs can be turned relative to the load bearing Implement. In order to achieve a turning movement of the wheel pairs towards a curve-radial adjustment which depends on the curve radius of the currently used track, the respective steering rods 9 are directly coupled to the load bearing implement 1 in coupling points 10.

Abstract: An air-cooled electric rotary machine includes a stator with a stator core formed of laminations and having axial ends, which terminate in winding end portions, and a rotor, which is encircled by the stator with an air gap therebetween. Plural air channels, separated from one another, are formed in or at the stator core for allowing an air stream in complementary flow directions, wherein the air stream is generated by a single fan and deflected at the winding end portions in a looped air stream conduction.

Abstract: A coupling element unit with spring action is located between a car body and an undercarriage of a railway vehicle. To largely relieve the coupling element unit from forces that act at a right angle to the suspension direction, a sliding adapter is provided that has two sliding elements and that can be displaced with respect to one another parallel to a floor of the car body.
