Raw cross force；Equipment must be by other by way of lateral guiding force is generated, and the two sides such as on the base of the rail, which are installed, to slope inwardly
Arc-shaped U-shaped aluminium sheet, car body also accordingly install inclined magnet；Aluminium sheet, the magnet of two sides denounce the electromagnetism of the introversion of generation
The vertical component of power provides suspending power for car body, and cross stream component provides guiding force for car body: when car body is located at center, two sides
Electromagnetic repulsion force cross stream component it is equal, not to car body generate guiding force, when car body is amesiality, the cross of the side electromagnetic repulsion force
Increase to component, and the other side becomes smaller, and then the guiding force of fitting center position is generated to car body.Such equipment does not need work
In the superconductive element of ultralow temperature, preparation, use cost are low.But it has the following problems: 1, separating suspension with electromagnetic repulsion force
A part is used as guiding force, reduces the suspending power of equipment.Meanwhile guiding force is also the difference composition of two sides cross stream component,
Guiding force is small, and guidance capability is poor.2, when car body is amesiality, not only the cross stream component of the side electromagnetic repulsion force increases, and vertical is outstanding
Floating component also increases, and will lead to tilting of car body；Namely car body can also add generation while swing and tilt shaking.Separately
Outside, what control side clearance needs were complicated detects and controls means, and it is at high cost that the device is complicated.3, body gravity is higher, and not position
When the surface of two sides electromagnetic repulsion force intersection point, run-off the straight is unable to control and is adjusted by car body, leads to car body operation not
Stablize.And in fact, limited by car body machining accuracy, the mass center of car body itself be difficult positioned at two sides electromagnetic repulsion force intersection point just on
Side, in the process of running, uncontrollable due to the position passenger-cargo, the position of centre of gravity that also not can guarantee car body is located at two sides electromagnetic repulsion force
The surface of intersection point.4, what control side clearance needs were complicated detects and controls means, and the device is complicated, and preparation use cost needs
It reduces.
