Problems solved by technology

[0003] In order to achieve suspension without energy consumption, permanent magnet suspension is used in China, but the suspension state of the permanent magnet is unstable, and the left and right guidance needs the auxiliary support of mechanical guide wheels. There is still mechanical friction, and complete suspension has not been achieved.

Embodiment Construction

[0049] The present invention is described in further detail in conjunction with accompanying drawing now.

[0050] like figure 1 Shown is the principle diagram of the permanent magnetic levitation technology of the present invention. The outer permanent magnet (1) and the inner permanent magnet (2) are all strong permanent magnets, such as NdFeB material, NdFeB 2 Fe 14 B / α-Fe can also be a newly developed strong permanent magnet with higher cost performance. The cross sections of the outer permanent magnet (1) and the inner permanent magnet (2) are concentric circles or half of the concentric circles, and can also be part of a circle, such as a superior arc or a inferior arc. The outer permanent magnet (1) and the inner permanent magnet (2) are basically concentrically arranged, and the magnetic pole direction of each permanent magnet is the same magnetic pole (such as N pole) inside, and another kind of magnetic pole (such as S pole) outside, and When the permanent magnet...

Abstract

The invention provides a permanent magnetic suspension technology and a device featuring simple structure, easy manufacture, low cost and easy promotion. The invention uses reasonable repel force of the magnetic field of the permanent magnet to realize permanent magnetic suspension thoroughly, has the characteristics of non mechanical contact friction resistence, low manufacture cost of line construction and secure and stable running, consumes no electricity for suspension, and has obvious energy and electricity conservation advantage and especially in low speed running condition the energy and electricity conservation advantage is better than the existing wheeltrack trains for times. The invention is very suitable for permanent magnetic suspension high-speed inter-city train, city subway,streetcar and light rail train, is applicable to production assembly and convey belt in the fields such as mechanics, electronics industry, food industry, industrial production, medicinal and hygieneand the like, as well as magnetic suspension convey lines of coal and ore and permanent magnetic suspension rotary base and permanent magnetic suspension handcrafts, toys, gifts and the like, has interest and knowledge, and is very amazing and interesting.

Description

Technical field [0001] The invention relates to the technical field of magnetic levitation, in particular to a permanent magnetic levitation vehicle, a permanent magnetic levitation track, permanent magnetic levitation toys and handicrafts. Background technique [0002] With the depletion of oil resources worldwide, various countries are developing new energy-saving and fuel-saving technologies, and vigorously promoting energy-saving and emission-reducing technologies and products. In order to promote economic development, increase the speed of material circulation, vigorously promote the flow of talents, and improve transportation capacity, various countries are stepping up the development of high-speed trains. Among them, the safe, high-speed, comfortable and low-noise maglev train has attracted much attention and praise. The maglev train has no mechanical friction, only air resistance, and the running friction resistance is very small. It is currently recognized as the m...
