Embodiment

In order to make those skilled in the art person understand the present invention program better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

See figures.1.and.2, the present invention is that a kind of magnetic floats vehicle damping mechanism, comprises spacing collar and is contained in the magnetic suspension damper mechanism in described spacing collar; Described magnetic suspension damper mechanism comprises by shake portion and buffer part, describedly comprises upper magnet yoke 5 and lower yoke 6 by shake portion; Described buffer part comprises location sliding axle 4 and at least two-layer magnetic shoe sheet, described at least two-layer porcelain tile there is endoporus, described two-layer porcelain tile relies on its inner hole sleeve to be contained on described location sliding axle 4, described at least two-layer magnetic shoe sheet and described location sliding axle 4 Spielpassung, a certain amount of sliding up and down can be done on the sliding axle 4 of location, between adjacent porcelain tile, homopolarity is mounted opposite, and leaves space each other, and enable maintenance slides up and down; The magnetic shoe sheet at two ends is arranged in described upper magnet yoke 5 and lower yoke 6 respectively, and the part of described upper magnet yoke 5 and lower yoke 6 is stretched out respectively and held as by shake from the stomidium at described spacing collar two ends; Described upper magnet yoke 5 and lower yoke 6 have center hole, the two ends of described location sliding axle 4 put in the center hole of described upper magnet yoke 5 and lower yoke 6, and and leave gap between the mounting point on the center hole top of described upper magnet yoke 5 and lower yoke 6, provide the space of compressional deformation to upper magnet yoke 5 and lower yoke 6.

With reference to Fig. 1, for a kind of specific embodiment of the present invention, comprise totally four layers of magnetic shoe sheet up and down in this embodiment, be respectively upper end porcelain tile 7, middle part magnetic shoe sheet 9, bottom magnetic shoe sheet 10 and the annular porcelain tile of lower end magnetic shoe sheet 8 four layers, concentric locking collar is contained on the sliding axle 4 of location, with described location sliding axle 4 Spielpassung, and peer is mounted opposite between above-mentioned four layers of porcelain tile, as shown in Figure 1, in adjacent porcelain tile, N is extremely to N pole, S extremely to S pole, and leaves gap between four layers of porcelain tile, enablely slides up and down.Damping effect and the materials cost of four layers of porcelain tile are the highest, and namely cost performance is the highest.Two-layer or three layers damping effect is not ideal enough, and five layers or more layers waste material again, but two, three, five or more layers are also in scope.

The principle of this device is: when upper magnet yoke 5 and lower yoke 6 are subject to impacting, upper magnet yoke 5 and lower yoke 6 slide up and down extruding multilayer magnetic shoe sheet along described location sliding axle 4 simultaneously, gap smaller between relative magnetic shoe sheet, according to magnetic field principle of same-sex repulsion, repulsion is produced between the porcelain tile of homopolarity, oppositely push upper magnet yoke 5 and lower yoke 6 up or down, after moment reaches balance up or down, namely reach the object of damping.Repeatable operation successively, plays the function of damping.This device utilizes magnetic field principle of same-sex repulsion to realize damping, without hydraulic oil, must not seal, and thoroughly solves the problem of oil sealing wearing and tearing leakage of oil.

Described upper magnet yoke 5 and lower yoke 6 part of stretching out outside described spacing collar stomidium is a disk, described disk has the attachment hole for being connected with automobile, in the present embodiment, attachment hole is circle center hole, wherein the circle center hole stretching out the part of described upper limit lid 1 of upper magnet yoke 5 is the first circle center hole 51, the circle center hole stretching out the part of lower limit lid 2 of lower yoke 6 is the second circle center hole 61, needs and determine its concrete shape according to as installed.

Preferably, in described at least two-layer magnetic shoe sheet, the porcelain tile at two ends is embedded in described upper magnet yoke 5 and lower yoke 6 that (in Fig. 1, upper end magnetic shoe sheet 7 is embedded in upper magnet yoke 5 bottom surface respectively, lower end magnetic shoe sheet 8 is embedded on lower yoke upper surface), or be connected in upper magnet yoke 5 and lower yoke 6 with other Placements.

Preferably, the location cylinder 3 that described spacing collar comprises upper limit lid 1, lower limit lid 2 and is connected between described upper limit lid 1 and lower limit lid 2, described upper limit lid 1 and lower limit lid 2 have the stomidium stretched out for described upper magnet yoke 5 and lower yoke 6.

Conveniently install, dismantle and keep in repair, preferably, be threaded between described location cylinder 3 and described upper limit lid 1 and lower limit lid 2.

Described upper limit lid 1 and lower limit lid 2 are button-type lid, tapping thread on button-type covered body wall internal surface, and location cylinder 3 places external threading outside two ends, thus are threaded in by location cylinder 3 on the inwall of described upper limit lid 1 and lower limit lid 2.

In order to avoid the magnetic shoe sheet (the middle part magnetic shoe sheet 9 in Fig. 1 and bottom magnetic shoe sheet 10) of centre and the sliding friction of location cylinder 3 and location sliding axle 4; porcelain tile (the middle part porcelain tile 9 in Fig. 1 and bottom magnetic shoe sheet 10) outer surface preferably in described at least two-layer magnetic shoe sheet between the porcelain tile of described two ends is set with outer jointing jacket 12, endoporus hole wall is inlaid with internal protective cover 11.

The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
