Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model is provided with the vibration damper of strong magnet.
Fig. 2 is P of the present utility model portion partial enlarged drawing.
Fig. 3 is the Placement schematic diagram of the utility model strong magnet and cylinder shell.
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 that the utility model is provided with the vibration damper of strong magnet.The described vibration damper that is provided with strong magnet comprises cylindrical shell 111, the first joint 1, the second joint 2, piston rod 3, dust-proof cover 4, piston 6, snap ring 222, strong magnet 51 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 vibration damper that the utility model is provided with strong magnet in use, described in be provided with the first joint 1 connecting vehicle frame of the vibration damper of strong magnet, the second joint 2 connects vehicle bridge.When being provided with the vibration damper of strong magnet when 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, and the throttling action of described flowing valve 8 and 9 pairs of fluid of compression valve makes the vibration damper that is provided with strong magnet produce the damping function while compressing.
When being provided with the vibration damper of strong magnet and being 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.The damping function when throttling action of described rebound valve 6 and 10 pairs of fluid of recuperation valve makes vibration damper produce stretching exercise.
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 and passage 22 (please refer to Fig. 2 partial enlarged drawing) with cylindrical shell 111.
When 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.
When 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, so passage 21 disappears with passage 22, and the damping that now vibration damper produces is larger.
Please refer to Fig. 3, the housing of described cylindrical shell 111 is hollow-core construction, and described strong magnet 51 is embedded in the hollow-core construction of described cylindrical shell 111 shells, and described strong magnet 51 can purify the fluid in oil storage cylinder 12.
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, increases the travelling comfort of driving, and can purify the fluid of oil storage cylinder 12 in vibration damper, extends the working life of vibration damper.
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.
