  • Patent number: 10266374
    Abstract: The disclosure relates to a lift installation having a lift car which can be moved along a guide rail. The lift installation here comprises at least a first pair of rollers and a second pair of rollers. The guide rail runs between the two rollers of the first pair of rollers and between the two rollers of the second pair of rollers. The lift installation also has an apparatus for subjecting the lift car to a retaining force, wherein there is a horizontal offset between the point at which the retaining force takes effect and the center of gravity of the lift car, and therefore the lift car is subjected to a first torque.

  • Patent number: 8297195
    Abstract: A method for operation of a magnetic levitation railway which contains vehicles with a plurality of supporting magnets (20a . . . 20j) and supporting runners (26) associated with them. In the event of a malfunction, the braking of the vehicle with the drive and braking systems switched off is brought about or assisted until a preselected destination stopping point is reached solely in that, even before the destination stopping point is reached, at least one of the supporting magnets (for example 20f, 20g) is switched off, and the magnetic levitation vehicle is placed on the track path (3) by means of the associated supporting runner (26), and is brought to rest at the destination stopping point by making use of the friction forces that occur as a result. A magnetic levitation vehicle is provided and operated in this way.

  • Patent number: 8166884
    Abstract: A switch assembly for magnetic levitation railways includes a girder extending in a travel direction (x) and flexible transversely to it is provided with travel way or equipment parts. A rail and a rack are located transversely to the travel direction. A load-bearing frame, receiving the girder, has a rotatably supported carrying wheel braced on the rail and a drive mechanism with a gear wheel meshing with the rack and with a motor intended for driving it. Switch adjustment is effected by displacement of the load-bearing frame along the rail by means of the drive mechanism and a thus-effected flexing of the girder. The girder, the load-bearing frame and the drive mechanism form a solidly joined-together structural unit which as a whole is located displaceably in the travel direction (x) relative to the rail and the rack.

  • Patent number: 7966942
    Abstract: The invention relates to a bending mount (24) for a switch arrangement for magnetically levitated railways. The bending mount comprises at least a box-shaped support element (25) that extends in the longitudinal direction (x) and on which are fixed successively arranged supporting metal sheets (27) that extend on both sides of the support element and serve to assemble the pieces of equipment (10, 12). According to the invention, the supporting metal sheets (27) are configured as single-piece components which extend over the width of the bending mount and are interlinked in the longitudinal direction to form a chain. Said chain essentially does not influence the flexural rigidity of the support element (25) in the desired direction (y) of a switching arrangement but exhibits a high rigidity against torsion about the longitudinal axis (x) and against vibrations in the vertical direction (z).
