Abstract
The utility model discloses a kind of shock absorber, including housing, decoupling rod, first hydraulic tube, second hydraulic tube, hydraulic cavities and compression spring, the hydraulic cavities are installed on the bottom of the housing, and the compression spring is set with the outer wall of the hydraulic cavities, the upper end of the compression spring is connected with the bottom of first hydraulic tube and second hydraulic tube, the upper end of the hydraulic cavities is connected with first hydraulic tube being arranged in the housing and second hydraulic tube respectively by joint, the decoupling rod is provided between first hydraulic tube and second hydraulic tube.The utility model provides a kind of shock absorber, by setting two-stage damping effect, when running into small vibration, damping filtering can be carried out by hydraulic pressure, and when running into big vibration, hydraulic pressure and compression spring act on simultaneously, reach that damping effect is optimal, ensure the stationarity and comfortableness of running car；The utility model has the advantages of simple in construction, stable performance and service life are longer.
Description
Technical field
It the utility model is related to absorber technical field, more particularly to a kind of shock absorber with two-stage damping effect.
Background technology
With the continuous development of society, requirement of the people to automobile also more and more higher, include dynamic property, the economy of automobile
Property, braking, control stability, ride comfort, the requirement by performances such as property.Shock absorber is mounted between car body and bogie wheel
A damping element, its act on be decay car body vibration and prevent the unlimited increase of resonant conditions lower body amplitude, can subtract
The amplitude and vibration number of small body oscillating, thus the fatigue life of flexible member can be extended and improve the comfortableness that people rides.
To accelerate the decay of body vibrations, improve vehicle running smoothness, shock absorber is equipped with the suspension of most of cars.
Commonly a problem existing for pellet type shock absorber is：Spring holder and fuel tank weld to be fixed, during with work
Between extension, the gradual aging of damper elastomeric element, reduced stiffness, its damping property is constantly degenerated, so as to have influence on garage
The stationarity and comfortableness sailed, it usually needs then change.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of shock absorber.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes housing, decoupling rod, the first hydraulic tube, the second hydraulic tube, hydraulic cavities and compression spring, described
Hydraulic cavities are installed on the bottom of the housing, and the compression spring is set with the outer wall of the hydraulic cavities, the compression bullet
The upper end of spring is connected with the bottom of first hydraulic tube and second hydraulic tube, and the upper end of the hydraulic cavities passes through joint point
Be not connected with first hydraulic tube being arranged in the housing and second hydraulic tube, first hydraulic tube with it is described
The decoupling rod is provided between second hydraulic tube.
The utility model is preferable, and the decoupling rod is connected after passing through the joint with compression spring seat, the compression bullet
Spring abutment is connected with the compression spring.
The utility model is preferable, and the upper end of the housing is provided with damping rod set, and the decoupling rod is in the decoupling rod
Moved up and down in set.
The beneficial effects of the utility model are：
The utility model provides a kind of shock absorber, by setting two-stage damping effect, when running into small vibration, and Neng Goutong
Cross hydraulic pressure and carry out damping filtering, and when running into big vibration, hydraulic pressure and compression spring act on simultaneously, reach damping effect most
It is good, ensure the stationarity and comfortableness of running car；The utility model has simple in construction, stable performance and service life longer
The advantages of.
Brief description of the drawings
Fig. 1 is the structural representation of shock absorber described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model includes housing 7, decoupling rod 2, the first hydraulic tube 3, the second hydraulic tube 4, hydraulic cavities 9
With compression spring 8, hydraulic cavities 9 are installed on the bottom of housing 7, and compression spring 8 is set with the outer wall of hydraulic cavities 9, compress bullet
The upper end of spring 8 is connected with the bottom of the first hydraulic tube 3 and the second hydraulic tube 4, and the upper ends of hydraulic cavities 9 is by joint 5 respectively with setting
The first hydraulic tube 3 and the second hydraulic tube 4 being placed in housing 7 connect, and are provided between the first hydraulic tube 3 and the second hydraulic tube 4
Decoupling rod 2, decoupling rod 2 are connected after passing through joint 5 with compression spring seat 6, and compression spring seat 6 is connected with compression spring 8, housing 7
Upper end be provided with damping rod set 1, decoupling rod 2 moves up and down in damping rod set 1.
In summary, the utility model provides a kind of shock absorber, by setting two-stage damping effect, when running into small vibration
When, damping filtering can be carried out by hydraulic pressure, and when running into big vibration, hydraulic pressure and compression spring act on simultaneously, reach and subtract
Best results are shaken, ensure the stationarity and comfortableness of running car；The utility model has simple in construction, stable performance and use
The advantages of lasting a long time.
Those skilled in the art do not depart from essence and spirit of the present utility model, can have various deformation scheme to realize this reality
With new, the preferably feasible embodiment of the utility model is the foregoing is only, not thereby limits to power of the present utility model
Sharp scope, all equivalent structure changes made with the utility model specification and accompanying drawing content, is both contained in the utility model
Interest field within.
