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. The permanent magnet driving maglev train can save energy by 60 to 90% compared with wheel / rail train when traveling at low speed below 80 kilometers per hour and save energy by about 50% compared with high-speed wheel / rail train when traveling at high speed above 200 kilometers per hour. The invention can realize the interchangeability of maglev rail and common rail, leading the maglev rail to universality, networkability and compatibility in modern transportation.

A simple permanent-magnet-excited maglev geometry provides levitation forces and is stable against vertical displacements from equilibrium but is unstable against horizontal displacements. An Inductrack system is then used in conjunction with this system to effect stabilization against horizontal displacements and to provide centering forces to overcome centrifugal forces when the vehicle is traversing curved sections of a track or when any other transient horizontal force is present. In some proposed embodiments, the Inductrack track elements are also employed as the stator of a linear induction-motor drive and braking system.

At least one ETT capsule travels within an evacuated tube, an upper and a lower cryostat respectively mount at the top and bottom of said ETT capsule along the length thereof, at least a plurality of superconductor levitation force elements divided between said upper and lower cryostats. The levitation force being spread over the length of capsule, however substantially concentrated in a compact cross-sectional area. At least a pair of permanent magnetic elements mounted at the top and bottom of the evacuated tube to cooperate with the superconductor elements to levitate the capsule.

The invention relates to the technical field of walking mechanisms for maglev vehicles, and particularly relates to a walking mechanism for middle / low-speed maglev vehicles. The walking mechanism for middle / low-speed maglev vehicles comprises at least two end part suspension frames and at least an intermediate suspension frame, each suspension frame comprises two longitudinal beams, sliding tables, air springs, a transverse draw bar and an anti-side-rolling draw bar, wherein the two longitudinal beams are arranged in a left and right mode, the sliding tables and the air springs are arranged in the middle of the longitudinal beams, each longitudinal beam is provided with a sliding table, the sliding table is fixedly supported on the longitudinal beam through the air spring, the sliding tables are connected through the transverse draw bar, the longitudinal beams are connected through the anti-side-rolling draw bar, the transverse draw bar and the anti-side-rolling draw bar are located in the middle of the suspension frame, the sliding tables of the intermediate suspension frame are provided with a linear guide rail extending along the transverse direction, the sliding tables of the intermediate suspension frame are connected with a train body through the linear guide rail, and the sliding tables and the longitudinal beams are connected through traction bars. The walking mechanism disclosed by the invention has the beneficial effects that as a method that the sliding tables are arranged in the middle of the suspension frames and a linear bearing replaces a swing bolster and a Z-shaped traction bar is adopted, the structure of the walking mechanism is simplified, and the walking mechanism is convenient to maintain.

The control system comprises 8 electromagnets which are arranged on the suspension module, 4 independent suspension controllers, a first sensor group and a second sensor group; the 8 electromagnets are divided into 4 electromagnet groups; each electromagnet group comprises two electromagnets which are connected in series; each suspension controller is connected with an electromagnet group through a chopper; the first sensor group and the second sensor group are respectively arranged at two ends of the suspension module; the suspension controller, the first sensor group and the second sensor group are connected through a CAN bus; the suspension controller is connected with the vehicle monitoring system of the maglev train. The distributed active fault-tolerant control system of the suspension module of the electromagnetic maglev train can tolerate failures of the controller, the sensor and the actuator in the suspension system, and thus greatly improve the reliability, stability and security.

This invention is a launch-to-space, refuel and return system which comprises: a unique circular and straight maglev track and maglev sled spacecraft launcher; a single stage-to-LEO spacecraft (Mother Spacecraft); an orbiting space platform (OSP); a currently utilized Space Shuttle is altered to improve its safety, range, longevity and versatility which serves as a prototype for the Mother Spacecraft design. The Mother Spacecraft is releasably attached to the maglev sled and propulsion for the maglev sled is supplied by magnetic propulsion and on-board rocket propulsion. The collapsible OSP can fit into the Space Shuttle storage bay and is remotely deployed. The OSP is a refueling depot for the Mother Spacecraft, the Space Shuttle, as well as a rendezvous point for various space missions. A single, liquid, non-cryogenic rocket fuel is standardized throughout the entire system which eliminates: all vertical launches; all expendables; all solid rocket propellants.
