Abstract: A drive device has a superimposed transmission, an input shaft connected a main drive machine, one or more auxiliary drives, a hydrodynamic retarder for braking the auxiliary drive, and an output shaft to be connected to a working machine. The superimposed transmission has a planetary transmission, with the input shaft connected to a ring gear and the output shaft connected to a sun gear. The retarder is incorporated into a lubricating oil system of the drive device in parallel. A feed line branches from the lubricating oil system and leads to the retarder. A return line leads from the retarder and opens into the lubricating oil system. A valve enables the feed line to be released in the event of a rapid disconnection or energy supply failure of one of the drives, and thus the retarder can be filled with oil.

Abstract: The current invention relates to a triggering monitoring device for a deformation tube having two tube parts which can slide into each other against resistance in a coupling, in particular a train coupling, having a housing that includes a connection for connecting to the deformation tube and at least one working surface for action of one tube part during its movement relative to the other tube part of the deformation tube part, wherein the housing can be deformed through the action of the tube part on the working surface. The triggering monitoring device according to the invention is characterized in that a sensor is provided in or on the housing which detects deformation of the housing and which is moreover equipped to transmit detection of a deformation to an evaluation device.

Abstract: A drive system has a main electric drive and an auxiliary electric drive. A frequency converter controls a torque of the auxiliary drive. A planetary gear has a ring gear, a sun gear, a planet gear and a planet gear carrier. The ring gear is coupled to the main drive, the sun gear is coupled to an output shaft and the planet gear carrier is coupled to the auxiliary drive. A clutch path is disposed between the planet gear carrier and the input shaft. A controller operates the drive system in a first range with the clutch closed and the switching apparatus open, or in a second range with the clutch open and the switching apparatus closed. The controller is adapted to superelevate the torque of the auxiliary drive during a transition between the first and second ranges beyond the torque that the auxiliary drive is able to provide permanently.
