That is to say, the suspension module 4 is a superconducting magnet made of a permanent magnet or a superconducting wire with a Halbach array structure; the suspension rail 5 is an aluminum or copper suspension rail, or a coil inductor formed by winding a coil.
For example: the suspension module 4 may be a superconducting magnet made of a permanent magnet or a superconducting wire, or both, and is mounted on the vehicle body 3. Such as: the suspension module 4 installed on the vehicle can be a permanent magnet or a superconducting magnet made of superconducting wires, and has the same function; wherein, the permanent magnet is preferably in a halbach array structure.

Wherein, any inductor in aluminum plate inductor, copper inductor, the coil inductor that forms by the coil coiling, make the line go the line direction all-line lay and fix and set up on the transfer passage along going.
For example: the inductor of the suspension rail 5 can be an aluminum inductor or a copper inductor or an inductor formed by winding coils and laid along the whole line.

Wherein the levitation module 4 interacts with the levitation track 5 to provide a majority of the levitation force. The suspension module 4 can adopt a passive magnetic suspension technology, and utilizes the fact that when a vehicle runs, the suspension track inductor cuts the magnetic force lines of the magnets on the vehicle, so that eddy current induction is generated inside the inductor, a magnetic field which is repulsive to the magnetic field of the magnets on the vehicle is formed, and suspension force is generated. The suspension module 4 provides most of suspension force required by vehicle suspension, and because the suspension module belongs to passive magnetic suspension, active control is not required, and the suspension does not consume energy, so that the energy is saved.
Therefore, the magnetic conduction effect is better and the suspension is safer through the manufacturing of the permanent magnet or the superconducting coil.
Optionally, the structure and number of the iron cores in the stator 1 may be adjusted according to a target normal suction force matched with a suspension force of a preset ratio or more, and may be used to assist the vehicle body 3 in suspending.
For example: the scheme of the invention adopts a unique mechanism design to adjust the normal suction force of the motor, thereby effectively utilizing the motor and saving the energy consumption of the system. The stator 1 is laid along the whole line of the line. Preferably, partial normal suction force can be provided by adjusting the structure and the number of the iron cores, so that the vehicle suspension is assisted, and the use efficiency of the motor is improved.

For example: as shown in fig. 4, the linear motor unit may include a mover 2 and a stator portion (e.g., a stator 1), wherein the stator portion is composed of a stator winding 6, an air-cored stator 7, a tooth portion iron core 8 and a jaw portion iron core 9; the normal suction force is adjusted by adjusting the structures of the tooth portion iron core 8 and the jaw portion iron core 9.

Therefore, the normal suction force of the linear motor is adjusted in multiple modes, on one hand, the normal suction force is flexibly adjusted according to requirements, and on the other hand, the reliability and safety of the adjustment of the normal suction force are guaranteed.
Optionally, the shape of the short-side end face of the suspension module 4 may include: arc, rectangle, L-shape, or triangle.
For example: the levitation module 4 may have various forms of levitation structures. Such as: the suspension module 4 is not necessarily arc-shaped, and may be in various forms such as plane, L-shaped, triangular, etc.
From this, through the suspension module of multiform, can be applicable to multiple suspension occasion, application scope is wide, and the suspension reliability can obtain guaranteeing.
Optionally, the motor gap of the linear motor can be adjusted by a lead screw adjusting mechanism, a hydraulic adjusting mechanism, an air spring adjusting mechanism, or an electromagnetic adjusting mechanism.

That is, the motor gap needs to be adjusted, which can be achieved in different ways. Such as: screw adjustment, hydraulic adjustment, air spring adjustment, electromagnetic adjustment, and the like. For example: the screw adjustment mechanism in fig. 8 is, for example, the adjustment mechanism 13, and the adjustment mechanism may be adjusted by a screw, or may be adjusted by a hydraulic pressure adjustment, an air spring adjustment, an electromagnetic adjustment, or the like.
Therefore, the motor clearance is adjusted in various modes, the adjusting mode is convenient and flexible, and the adjusting result is reliable and accurate.

As shown in fig. 7, the running part of the hybrid magnetic levitation vehicle may include: the magnetic levitation module 4, the wheel 11 and the frame 12, and other accessories.
