Abstract

The utility model discloses a kind of stable movement shock absorber piston lever arrangement, comprise piston rod, one end of described piston rod connects piston, and the other end connects upper bracket; Described piston rod is provided with oil sealing and guider assembly near one end of upper bracket; Described piston rod is socketed with circular limit fixed sleeve, and described limit fixed sleeve is fixedly connected with described piston rod; The centre of described guider assembly and described limit fixed sleeve is provided with the flexible and buffer limit cover that can slide on the piston rod.Buffer limit cover not only can the collision of buffer-oriented device assembly and limit fixed sleeve, but also the effect that can the motion of piston rod is played guiding and be located, ensure that the piston movement of piston rod is steady.

Description

A kind of stable movement shock absorber piston lever arrangement
Technical field
The utility model relates to automobile absorber technical field, particularly relates to a kind of stable movement shock absorber piston lever arrangement.
Background technique
Concussion when vibration damper rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface.Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is just used to suppress this spring to jump.Vibration damper is too soft, and vehicle body will vertical bounce, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.About in the retrofit process of suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, and therefore heavier car generally adopts harder vibration damper.
The structure of vibration damper is in the piston rod insertion cylinder with piston, in cylinder, be full of oil.Piston there is throttle orifice, the oil in two-part space separated by piston can be complemented each other.Damping produces by during throttle orifice at the sticking oil of tool, and throttle orifice is less, and damping force is larger, and the viscosity of oil is larger, and damping force is larger.
CN2357179Y discloses a kind of automobile absorber Wear-resisting piston, its technological scheme be on the piston rod in chrome-plated surface at plating ceramic film, to increase its wear resistance; Its deficiency is, ceramic film easily comes off, and fragile, cannot ensure the stable use of piston rod, reduce working life.
Model utility content
The purpose of this utility model is the technological deficiency for existing in prior art, and the shock absorber piston lever arrangement a kind of accurate positioning being provided, operating steadily.
The technological scheme adopted for realizing the purpose of this utility model is: a kind of stable movement shock absorber piston lever arrangement, is characterized in that: comprise piston rod, and one end of described piston rod connects piston, and the other end connects upper bracket; Described piston rod is provided with oil sealing and guider assembly near one end of upper bracket; Described piston rod is socketed with circular limit fixed sleeve, and described limit fixed sleeve is fixedly connected with described piston rod; The centre of described guider assembly and described limit fixed sleeve is provided with the flexible and buffer limit cover that can slide on the piston rod.
Further, described limit fixed sleeve has aperture, aperture place is equipped with clamping bolt.
A more progressive step, the periphery of described buffer limit cover is provided with ring-type sawtooth.
Working principle of the present utility model and beneficial effect are: be provided with piston cylinder outside piston rod, when piston rod moves in piston cylinder, piston rod carries out spacing by limit fixed sleeve to the motion path of piston rod, after guider assembly and limit fixed sleeve collide, cause damage, flexible buffer limit cover is installed between the two; Buffer limit cover not only can the collision of buffer-oriented device assembly and limit fixed sleeve, but also the effect that can the motion of piston rod is played guiding and be located, ensure that the piston movement of piston rod is steady.
Accompanying drawing explanation
Figure 1 shows that a kind of structural representation of stable movement shock absorber piston lever arrangement.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment:
Be illustrated in figure 1 a kind of stable movement shock absorber piston lever arrangement, a kind of stable movement shock absorber piston lever arrangement, is characterized in that: comprise piston rod 1, and one end of described piston rod 1 connects piston, and end is provided with the piston assembly 6 be connected with piston; The other end of described piston rod 1 connects upper bracket, and end is provided with the bolt for connecting upper bracket nut; Described piston rod 1 is provided with oil sealing 2 and guider assembly 3 near one end of upper bracket; Described piston rod 1 is socketed with circular limit fixed sleeve 5, and described limit fixed sleeve 5 is fixedly connected with described piston rod 1; Described limit fixed sleeve 5 has aperture, and aperture place is equipped with clamping bolt.When piston rod 1 moves in piston cylinder, piston rod 1 is undertaken spacing by the motion path of limit fixed sleeve 5 pairs of piston rods 1,
Further, after guider assembly 3 and limit fixed sleeve 5 collide, cause damage, be provided with flexible buffer limit cover 4 between the two, the periphery of described buffer limit cover 4 is provided with ring-type sawtooth.Buffer limit cover 4 not only can the collision of buffer-oriented device assembly 3 and limit fixed sleeve 5, but also can play the effect of guiding and location to the motion of piston rod 1, ensure that the piston movement of piston rod 1 is steady.
The above is only preferred implementation of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.

Claims (2)
