The technical solution of the utility model is: described vibration damper comprises cylindrical shell, piston rod, piston, snap ring, base and strong magnet, and described cylindrical shell comprises oil storage cylinder and inner casing, and the bottom of described oil storage cylinder is communicated with the bottom of inner casing; Described piston rod inserts from cylindrical shell upper end portion, described inner casing is divided into upper cylinder half and lower cylinder, described piston rod can move up and down in the internal vertical direction of cylindrical shell, described piston is connected with the underpart of piston rod, described piston comprises rebound valve and flowing valve, the diameter of described piston is less than the diameter of inner casing, described snap ring is connected with the sidewall of lower cylinder, the equal diameters of its diameter and piston, described base is positioned at lower cylinder bottom portion, and described base comprises compression valve and recuperation valve, and described base is connected with snap ring, wherein, on inner casing sidewall more than snap ring, be inlaid with strong magnet.
Further, described strong magnet dents into 1 millimeter of cylinder lateral wall.
Vibration damper described in the utility model, can there are little damping force and large two gears of damping force, can regulate according to the shock conditions of vehicle body, thereby strengthen the travelling comfort of driving, and, by strong magnet absorption iron filings are installed on the sidewall of inner barrel, extended the working life of vibration damper.

Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
Please refer to Fig. 1, Fig. 1 is the structural representation of the utility model vibration damper.Described vibration damper comprises cylindrical shell 111, the first joint 1, the second joint 2, piston rod 3, dust-proof cover 4, piston 6, snap ring 222 and base 13.
Described cylindrical shell 1 comprises oil storage cylinder 12 and inner casing 121, and the bottom of described oil storage cylinder 12 is communicated with the bottom of inner casing 121.
Described piston rod 3, the inside of inserting cylindrical shell 111 from the top portion of described cylindrical shell 111, described piston rod 3 can move up and down in the internal vertical direction of cylindrical shell 111.
Described piston 6 is connected with the underpart of piston rod 3, and described inner casing is divided into upper cylinder half 5 and lower cylinder 11.The left end of described piston 6, is provided with rebound valve 7.The right-hand member of described piston 6 is provided with flowing valve 8, and the diameter of described piston 6 is slightly less than the diameter of inner casing 121.
The utility model is provided with a snap ring 222 in the bottom of described cylindrical shell 111, described snap ring 222 is connected with the sidewall of lower cylinder 11, the equal diameters of its diameter and piston 6;
Described base 13 is positioned at lower cylinder bottom portion, and described base is provided with compression valve 9 and recuperation valve 10, and described base 13 is connected with snap ring 222.
Described dust-proof cover 4 is connected with described piston rod 3 tops, covers the top of described cylindrical shell, prevents that dust from entering vibration damper inside from the top of cylindrical shell 111, affects the working life of vibration damper.
Described the first joint 1 is connected with the top of piston rod 3, and described vibration damper is connected with vehicle frame by the first joint 1.Described the second joint 2 is connected with the bottom of cylindrical shell 111, and described the second joint 2 is for connecting vehicle bridge.
The utility model vibration damper in use, the first joint 1 connecting vehicle frame of described vibration damper, the second joint 2 connects vehicle bridge.In the time that vibration damper is compressed, piston rod 3 is descending, and the volume of upper cylinder half 5 increases, and the volume of lower cylinder 11 reduces.Now, flowing valve 8 is opened, and the fluid of lower cylinder 11 enters upper cylinder half 5 by flowing valve 8; Meanwhile, compression valve 9 is opened, and fluid enters oil storage cylinder 12 by compression valve 9, damping function when described flowing valve 8 makes vibration damper produce compression with compression valve 9 to the throttling action of fluid.
In the time that vibration damper is stretched, piston rod 3 is up, and the volume of upper cylinder half 5 reduces, and the volume of lower cylinder 11 increases.Now, the fluid of upper cylinder half 5 enters lower cylinder 11 by rebound valve 6, opens recuperation valve 10 simultaneously, and fluid enters lower cylinder 11 by oil storage cylinder 12.Damping function when described rebound valve 6 makes vibration damper produce stretching exercise with recuperation valve 10 to the throttling action of fluid.
Especially, because the diameter of piston 6 is slightly less than the internal diameter of cylindrical shell 111, therefore, above snap ring 222, piston 6 is formed with passage 21 with cylindrical shell 111 and please refer to Fig. 2 partial enlarged drawing with passage 22().
In the time that piston rod 3 moves above snap ring 222, the now effect of passage 21 is equivalent to rebound valve 7, and the effect of passage 22 is equivalent to flowing valve 8, and now, the damping function that vibration damper produces is less.
In the time that piston rod 3 enters snap ring 222 and once moves, due to the equal diameters of diameter and the piston 6 of snap ring 222, therefore passage 21 disappears with passage 22, and the damping that now vibration damper produces is larger.
On more than 222 inner casing 121 sidewalls of described snap ring, be inlaid with magnetic material.Because the diameter of piston 6 is slightly less than the diameter of cylindrical shell 111, therefore, piston 6 does not directly contact with cylindrical shell 111.Therefore can inlay strong magnet on the sidewall of the internal surface of cylindrical shell 111, for adsorbing the impurity such as iron filings, reach the technique effect of Jinhua fluid, thereby increase the working life of vibration damper.
Further, the impurity such as the iron filings of described cylindrical shell 111 internal surface absorption stop up passage 21 and passage 22, affect the regulating effect of the utility model to damping, and described strong magnet preferably dents into a bit of distance of sidewall.As shown in Figure 3, strong magnet 31 depression distance as a bit of in sidewall, preferably caves in 1 millimeter.
By the setting of this structure, vibration damper described in the utility model has had and has produced the gear of two dampings when violent with vibrations vibrations are slight, increase the travelling comfort of driving, and the working life of vibration damper is longer.
These are only mode of execution of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
