  • Patent number: 8430038
    Abstract: A line-changing device for magnetic levitation trains includes a rail section, at least one rail positioned transversely thereto, and a support frame for the rail section, which includes at least two wheels supported on the rail. The support frame includes a support module connected with the rail section, and two wheel modules attached to the sides thereof in a replaceable manner, and in which at least one of the wheels is rotatably supported.

  • Patent number: 8371228
    Abstract: The invention relates to a flexible steel support (31) for a switch arrangement in maglev railways. The flexible support (31) contains a hollow profile (32) that extends in a longitudinal direction (x) and a hollow profile that can be bent in a transverse direction (y) and that is provided with lateral sheet metal struts (35) and a top flange (33). The support is also provided with a plurality of cantilever arms (38) that extend in the transverse direction (y), are interspaced in the longitudinal direction (x) and are connected to the sheet metal struts (35) and a plurality of metal cover sheets (42) that are arranged one behind the other in the longitudinal direction (x) and are supported on the cantilever arms (38), the connections between the sheet metal struts (35), cantilever arms (38) and metal cover sheets (42) consisting of welded joints.

  • Publication number: 20060032395
    Abstract: Disclosed is a module (10) for the driveway of a magnetically levitated vehicle. Said module (10) comprises functional surfaces (17, 18, 19) in the form of at least one laterally guiding assembly surface, one gliding assembly surface, and one stator pack assembly surface. The functional surfaces (17, 18, 19) are embodied on oversized pieces of equipment (14, 15, 16) which are made of steel, are connected in a fixed manner to the module (10), and are machined down in a cutting manner to a predefined set point dimension. Also disclosed are a driveway which comprises such modules and a method for producing said modules (10). The inventive method includes a step in which the modules are twisted in an elastic manner prior to being fixed to the beams in order to create changes in the lateral inclination.

  • Patent number: 6739267
    Abstract: A movable track connection between the ends of travel paths for wrap-around track-guided vehicles, especially magnetic levitation railway vehicles is provided. The moveable track connection has a set of S-shaped deformable bending points (1) for changing track. A bearing (4, 6) along half the length of deformable bending points has a vertical axis of rotation, which cannot move in the longitudial direction of the bending points (1).

  • Patent number: 4923253
    Abstract: A braking system for an aircraft towing vehicle which supports the nose wheel of an aircraft in a raised position and firmly clamps it to the vehicle. The braking force generated by the front wheels of the towing vehicle is greater by about 2:1 to 8:1 than the braking force at the rear wheels. The braking system has two hydraulic circuits employing identical braking cylinders at all four wheels of the vehicle. The number of cylinders per wheel are varied and different effective lever arms are used to generate like braking forces at each side of the vehicle, and the relatively greater braking force at the front wheels, even if one of the hydraulic circuits fails. The system limits the braking force at the front and rear wheels to maximum values to prevent excessive forces from damaging the nose gear of relatively smaller aircraft.
