Patent number: 8166884Abstract: 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.Type: GrantFiled: January 10, 2007Date of Patent: May 1, 2012Assignee: ThyssenKrupp Transrapid GmbHInventors: Qinghua Zheng, Friedrich Loeser, Xiufei Liu

Patent number: 7966942Abstract: 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).Type: GrantFiled: January 10, 2007Date of Patent: June 28, 2011Assignee: Thyssenkrupp Transrapid GmbHInventors: Qinghua Zheng, Friedrich Loeser, Xiufei Liu
