Abstract
The present invention relates to a permanent magnetic suspension device of a suspending rail, which comprises a guide rail and a sucking suspension mechanism, wherein the part of the guide rail is composed of four single rails which are arranged in parallel. Every two single rails are in one group and in a n shape, and are symmetrically fixed at both sides of the lower side of a base of the suspending rail. The part of the sucking suspension mechanism is composed of eight sucking suspension units which are arranged in parallel. Every fourth sucking suspension units are in one group and in a reverse M shape, and are symmetrically fixed at the left and the right of both sides above a top disk of a sucking suspension device. Each group of sucking suspension units are corresponding to each group of single rails on the guide rail. The single rails on the guide rail are inserted between two sucking suspension units on the sucking suspension mechanism in parallel. An air gap is arranged between each single rail and one sucking suspension unit which is adjacent to the single rail. When the height of a permanent magnet of the sucking suspension mechanism and the height of the single rails in the guide rail of the device are the same, upward suspension attraction is zero, the sizes of left attraction and right attraction are the same, the directions of the left attraction and the right attraction are opposite, and the left attraction and the right attraction mutually counteract. When the permanent magnet of the sucking suspension mechanism is lower than the single rails in the guide rail, upward attraction is generated to suspend the sucking suspension mechanism below the guide rail.

Description of drawings
Fig. 1 is the plane of structure structural representation of permanent magnetic suspension apparatus of suspending rail of the present invention.
The specific embodiment
Below describing is the detailed description of in conjunction with the accompanying drawings the present invention being done, and should not be construed limitation of the invention.
See also Fig. 1, have four single tracks 1 in the guide rail, per two is one group of totally two groups of both sides that are fixedly installed on hanger rail base 4 below line of centerss, and each group is the П type and is parallel to each other.The structure of single track 1 is: the centre is ferrimagnetism guide rail base 1a, be fixed with four flute profile magnetic conduction rail 1b in the upper and lower of guide rail base 1a both sides symmetrically, be provided with nonferromagnetic mosaics 1c (being such as but not limited to aluminum alloy materials) between two flute profile magnetic conduction rail 1b up and down.
Please continue to consult Fig. 1, inhale suspension mechanism and have eight and inhale floating units 2, per four be one group totally two groups be the mountain font and be fixedly installed on and inhale levitation device 3 and take over a business 3a both sides, top and be parallel to each other, and be placed in the single track 1 of hanger rail base 4 belows in the corresponding guide rail.The structure that each group is inhaled floating unit 2 is: three permanent magnetism base 2a are fixed on the top of 3a, and in the both sides of dual-side permanent magnetism base 2a inboard and middle permanent magnetism base 2a, each fixes a permanent magnet 2b (being such as but not limited to nd-fe-b) its top and the bottom.Permanent magnet 2b is set to adjacent two and is heteropole, promptly wherein one be the S utmost point, cooresponding another is the N utmost point.Be provided with nonferromagnetic mosaics (being such as but not limited to aluminum alloy materials) 2c between two heteropole permanent magnet 2b up and down.
