  • Patent number: 8610322
    Abstract: The invention relates to a magnetic bearing and to a method for operation thereof. The magnetic bearing contains a ferromagnetic, movably mounted bearing element (1) and at least two magnetic devices (3o, 3u) arranged on opposing sides of the bearing element (1) and equipped with windings (6), wherein during operation of the magnetic bearing, electric currents are conducted through the windings (6) and these currents are regulated such that in an equilibrium state between the bearing element (1) and the two magnetic devices (3o, 3u), bearing gaps (10o, 10u) of predetermined size (So, Su) form. According to the invention, the temperatures produced in the magnetic devices (3o, 3u) during operation are measured and the regulation of the currents takes place such that in the equilibrium state, regardless of the load situation, the same temperatures appear in the magnetic devices (3o, 3u) or in the windings (6) thereof (FIG. 1).

  • Patent number: 8430037
    Abstract: The invention relates to a magnetic levitation train, comprising a track system formed of track system carriers (2) and a vehicle (1) having at least one first magnetic system (7), which together with stator packs (4) mounted on the track system forms a long stator linear motor and during operation is disposed at a distance from the stator packs (4) by a small carrying gap. According to the invention, first sound damping bodies (14) are disposed on the carriers (2) in a space which is located between the carrier (2) and the magnetic system (7) and the carrying gap when a vehicle (1) passes. In addition, second sound damping bodies (15) are provided on the vehicle (1) on the side of the magnetic system (7) facing away from the carrier (2).

  • Patent number: 8402899
    Abstract: The invention relates to a maglev railway comprising a support and drive system of the long stator-linear motor type, magnetic support poles that are situated in the vehicle being additionally provided with linear generator windings (10) that generate electric energy in the vehicle. The aim of the invention is to prevent unwanted, periodic vibrations (ripples) from being generated at low speeds. To achieve this, according to the invention, the teeth (5) and grooves (6) of the long stator (3) are arranged in high-speed sections (2a) parallel to the cores and the linear generator windings (10) of the support magnets provided in said cores and in low-speed sections (2b) obliquely to said cores (7) and linear generator windings.

  • Patent number: 8052161
    Abstract: A wheel suspension for a motor vehicle has a transverse control arm that can be attached to a vehicle body by way of bearings and a spring-elastic torsion bar assembly, and can be rotated about a longitudinal axis. The torsion bar assembly has a body spring that can be attached to the vehicle body with one end, and a transverse control arm spring that is attached to the transverse control arm with one end. The body spring and the transverse control arm spring are coupled with one another at their free ends. The transverse control arm spring and the body spring are coupled with one another by way of a setting element or a releasable connection, whereby the setting element or the releasable connection, respectively, allows rotation of the ends assigned to one another, for setting purposes.
