Abstract: A transport vehicle includes two non-steered drive wheels, two non-driven steered load wheels, drive motors for driving the drive wheels, a steering target value encoder, a device for detecting the steering angle of one of the load wheels, and an electric control unit. An actuation of the steering target value encoder displaces a steering pole along a steering pole axis. The steering target value encoder steers each of the load wheels from a first position in which the load wheels' axes run parallel to the drive wheels' axes into a second position in which the load wheels' axes are oriented to the steering pole which lies between the drive wheels. The electronic control unit influences a rotational speed of the drive motors as a function of the steering angle and reverses a direction of rotation of at least one of the drive motors as a function of the steering angle.

Abstract: A multidirectional transport vehicle includes a longitudinal axis which defines a longitudinal direction, a transverse axis which defines a transverse direction, a steering system, a driving direction switch, and a driving direction adjustment element. The steering system comprises at least three independently steerable wheels and a steering target value transmitter which steers the wheels. Each wheel has a wheel axle. A steering pole, on which each wheel axle is aligned when cornering, is moved along a steering pole axis by actuating the steering target value transmitter. The driving direction switch includes a limited number of separate switch positions, wherein exactly one switch position preselects exactly one respective rotational position of the steering pole axis relative to the multidirectional transport vehicle and preselects one of two driving directions facilitated thereby. The driving direction adjustment element changes a preselectable rotational position of the steering pole axis.

Abstract: A method for operating an industrial truck having three wheels. During longitudinal travel, two steerable wheels run in succession in a first lane, and a third wheel runs in a second lane. The third wheel initially runs on an inside during a turning in while cornering until the industrial truck, during a further turning in, transitions into a revolving motion. The method includes reducing a drive power as of a specific steering angle during the turning in prior to the revolving motion, and disengaging or reversing a direction of a drive rotation of the third wheel after a delay time which begins with the reducing of the drive power, or, continuously reducing the drive power from the specific steering angle during the further turning in, and disengaging or reversing the direction of rotation of the third wheel when transitioning into the revolving motion.

Abstract: The invention relates to a synchronously excited rotary machine with a superconductive rotor comprising a plurality of projecting first pole units of a magnetic material and a plurality of second pole units having superconductive coils wrapped around a core element of a magnetic material. Each second pole unit is positioned between two adjacent first pole units. The second pole units are spaced apart from aback iron and the first pole units via a plurality of thermally insulating support elements, wherein this spacing is evacuated so that it acts as magnetic air gap. An enclosed housing is provided on the back iron in which the first and second pole units are arranged, where-in the superconductive coils of the second pole units are in fluid communication with a cooling system. The first pole units and back iron are operated at an ambient temperature while the second pole units are operated at a cryogenic operating temperature.
