Patent number: 10173865Abstract: An example electromotive linear drive mechanism for moving walkways for conveying people or objects may comprise a long stator as an active primary part positioned along a direction of movement of a moving walkway, as well as a plurality of passive secondary parts that are movable with respect to the active primary part and are arranged with one another along the direction of movement. The long stator may have a plurality of successive long stator sections in the form of coil groups along the direction of movement. Each long stator section may have its own control device that is configured to move the secondary parts using control parameters stipulated for the respective long stator section. Further, example methods for operating the electromotive linear drive mechanism may involve predefining different movement profiles for the respective control devices for at least some of the long stator sections such that the secondary parts move along the long stator in a non-uniform manner.Type: GrantFiled: August 1, 2014Date of Patent: January 8, 2019Assignee: THYSSENKRUPP ELEVATOR AGInventors: Jürgen Frantzheld, Qinghua Zheng, Friedrich Löser

Patent number: 8234981Abstract: A magnetic polar arrangement which is intended for magnetic levitation vehicles is described, the magnetic polar arrangement having at least one magnetic pole (22) with a core (6) which defines a magnetic pole surface (23), and with a winding (5) which is set back with respect to the magnetic pole surface (23) in order to form a free space (24). The magnetic pole (22) is provided with a sensor which contains a sensor head (9a), which is arranged at least partially in the free space (24), and an electronic module (9b). According to the invention the sensor head (9a) is physically separated from the electronic module (9b) and is combined, at least with the core (6), to form a single-piece structural unit which is surrounded by a common anti-corrosion layer (26).Type: GrantFiled: August 13, 2007Date of Patent: August 7, 2012Assignee: Thyssenkrupp Transrapid GmbHInventors: Qinghua Zheng, Jürgen Frantzheld, Friedrich Löser

Patent number: 8118266Abstract: An apparatus generates position signals to indicate the position of a rail-bound vehicle along a travel way throughout which travel way many markings are located. The apparatus includes at least one sensor located on the vehicle for scanning the markings and outputting signals and an evaluation unit that is connected to the sensor for generating the position signals by evaluating the signals generated by the sensor by scanning the markings. When the vehicle passes a marking, the sensor outputs a “marking present” signal and otherwise outputs a “marking absent” signal. The vehicle has a receiver of a navigation system that is connected to the evaluation unit and outputs current location signals.Type: GrantFiled: January 10, 2007Date of Patent: February 21, 2012Assignee: ThyssenKrupp Transrapid GmbHInventors: Qinghua Zheng, Juergen Frantzheld

Publication number: 20090050751Abstract: The invention relates to a device for producing position signals, which indicates the position of a tracked vehicle along a vehicle track. The device comprises a plurality of markers (9) arranged along the vehicle track, a sensor (12, 14) fixed to the vehicle for scanning the markers (9) and an evaluation unit (17) connected to the sensor (12, 14). According to the invention, the markers (9) are configured in such a way that the sensor (12, 14) only generates a signal “marker present” when the vehicle passes the marker (9), otherwise it generates the signal “marker not present”. A receiver (18) of a global or local navigation system and a storage device (20) in which the position data associated with the markers (9) are stored are connected to said evaluation unit (17).Type: ApplicationFiled: January 10, 2007Publication date: February 26, 2009Inventors: Qinghua Zheng, Juergen Frantzheld
