  • 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.

  • Publication number: 20110271867
    Abstract: The invention relates to a linear permanent magnet driving system and a permanent magnet driving maglev train rail system, the linear permanent magnet driving system comprises spiral rotors and stators, wherein at least one of the spiral rotor and the stator adopts the structure having a permanent magnet while the other one adopts the structure having the permanent magnet or a magnetizer; when the spiral rotors are driven by an engine to rotate, linear motion of the spiral rotors is achieved by means of the magnetic force between both, and speed of the linear motion of the spiral rotors can reach supersonic speed at most. By applying the linear permanent magnet driving system to the permanent magnet driving maglev train rail system, the entire rail can avoid the use of both permanent magnet and driving coil, and the construction cost of maglev train rail is equivalent to that of the current high-speed wheel/rail.

  • Publication number: 20100199876
    Abstract: A switch is used, at the divergent zone, to cause the vehicle bogie to follow one path or the other in the guideway. This is accomplished by substituting an attracting magnetic array on the side that the vehicle bogie is desired to follow. The switch may operate without moving parts, so there is no inertial penalty to limit operational frequency. The switch is designed to fail gracefully in the absence of activation power or control signals. Further, the switch is designed to ensure that there would be no derailment or dropping of a vehicle.

  • Patent number: 7757609
    Abstract: A magnetically levitated transportation system employs permanent magnet rails along a guideway that interact with permanent magnets on a vehicle. The rails are optimized to reduce magnetic mass and cost of materials, while maximizing lift force. The vehicle is stabilized in the lateral and yaw directions with feedback controlled lateral control coils that interact with the permanent magnet rails on the guideway. A track switching structure employs permanent magnet rails that gradually widen along a segment of track and separate into two identical diverging rails. Feedback controlled lateral control coils in a moving vehicle stabilize that vehicle over one or the other pairs of diverging rails, as directed by a control computer, thereby causing the vehicle to continue along one path or the other, with no moving or active elements required in the track.

  • Patent number: 7617779
    Abstract: This disclosure describes an electromagnetic system for efficient propulsion, suspension, and guidance. The track is inexpensive totally passive steel. This linear form of the D.C. motor provides traction motor characteristics without physical contact, The moveable element (vehicle) comprises both the integrated armature and field magnet flux source which induces magnetizing flux into pairs of rails each energizing a set of interdigitated poles of alternating polarity in the track against which its own armature conductors interact for thrust and braking. This source of magnetic flux requires no power and provides passive suspension at any speed and, with control, guidance. The permanent magnet and control flux in common airgaps multiply the effectiveness of lateral control for magnetic stabilization and to restrain external forces.

  • Patent number: 6374745
    Abstract: The invention relates to a line-changing device for the tracks (1, 2) of a magnetic levitation train. The tracks (1, 2) are formed by track supports arranged one after the other and the lines are changed by means of a rail joint between the tracks (1, 2). To connect the tracks a track support configured as a bendable support (5) is positioned along each track which bendable support can be bent to establish a connection between the tracks (1, 2). In its bent state each bendable support can be positioned in relation to the other bendable support (5). Along each track (1, 2) a track support situated next to the bendable support (5) is configured as a connecting support (6), which when the rail joint is established can be moved out of the clearance gauge of the train. The invention consists in the fact that the connecting supports (6) can be moved without deformation.

  • Patent number: 6357358
    Abstract: A transport system has a pair of levitating rails, each of the levitating rails has a core with a plurality of coils extending circumferentially around each of the cores. The coils are perpendicular to the lengths of the levitating rails. Each of the levitating rails has an upper surface directly above the core. A vehicle has wheels that roll on the upper surfaces of the levitating rails in a nonlevitating position. The vehicle has a plurality of magnets that create magnetic fields that pass through the coils while the vehicle is moving along the levitating rails. The magnetic fields induce current, which in turn causes an opposing magnetic field that levitates the vehicle. A steering rail having a plurality of coils is mounted to at least one of the guideways. Permanent steering magnets are located on each side of the steering rail to magnetically steer the vehicle along the guideways.

  • Patent number: 6354225
    Abstract: A track-alternating arrangement for magnetic-levitation roadways, in which one of a series of mutually aligned bearers in each roadway establishes a first junction to join the roadways together. The bearer is inflectable to form the first junction. Each bearer, in an inflected state in one roadway, is aligned with another bearer in an adjacent roadway. An abutting one of the bearers adjacent the inflectable bearer is shiftable out beyond a free base of a car traveling over the roadway to provide sufficient space for the car to pass the junction. The abutting bearers are inflected to establish a different second junction. The inflectable bearers are shiftable out beyond a free cross-section of the car when the abutting bearers establish the different second junction.
