Description
Technical field
It the utility model is related to a kind of shock absorber applied in automobile suspension system.
Background technology
Shock absorber is housed inside the suspension system of most of automobiles, shock absorber also referred to as " is hung ", and shock absorber is mainly used
Concussion during suppressing bounce-back after spring shock-absorbing and the impact from road surface.Existing shock absorber, at two mounting distance at a distance of compared with
Remote mounting location is, it is necessary to shock absorber has longer size, to ensure rigidity, the working cylinder of shock absorber, liquid storage cylinder it is cylindrical
Size also can be accordingly larger, and often damping elastomer is poor for large-sized shock absorber, is also inconvenient to process；In addition, shock absorber is in work
It can be in when making and continuously compress and uphold process, it is excessive when there is extension stroke, easily cause piston upper surface with leading
To the improper contact in device lower surface, security reliability during damper work is influenceed.
The content of the invention
In view of the deficiencies in the prior art, the utility model provides a kind of damping property optimization, is easy to process and works
Safe and reliable tandem shock absorber.
The utility model is adopted the following technical scheme that to complete：
Tandem shock absorber, it is characterised in that：By the first damper components setting up and down and the second damper components string
Connection forms, and first, second damper components include working cylinder, liquid storage cylinder, piston rod, piston, compression valve and guider, liquid storage
Cylinder sleeve is located at the outside of working cylinder, and lid and lower cover are respectively fixed with the top and bottom of working cylinder, liquid storage cylinder, and compression valve is located at
In lower cover, guider is located in lid, and the lower rod end of endoporus and piston rod that piston is located at working cylinder connects, the upper boom of piston rod
End is through passing the upper lid after guider, rod end on the piston rod of the lower cover of the first damper components and the second damper components
It is fixedly linked, lower cover and the shock absorber installation suspension ring of the second damper components are fixedly linked.
Spacing ring seat is fixed with piston rod, spacing ring seat is provided with bump rubber, in the design maximum of piston rod
Extension stroke, the upper surface of bump rubber contact with the lower surface of guider.
The tandem shock absorber of above-mentioned technical proposal, equivalent to the tandem junction for employing two identical or different shock absorbers
Structure, therefore, although the mounting location apart from each other applied to two mounting distance, the appearance and size of shock absorber in itself can be selected
Select it is smaller, make shock absorber damping property optimize and also be easy to process；Further, since it is provided with yielding rubber inside shock absorber
Block, it is possible to avoid piston upper surface from being contacted with the improper of guider lower surface, make shock absorber safe and reliable, improve
Service life.
The utility model is further arranged to：The working cylinder of first damper components, the excircle dimension of liquid storage cylinder are small
The excircle dimension of working cylinder, liquid storage cylinder in the second damper components.By above-mentioned design, the first damper components and second subtract
Shake device part damping elastomer it is different, the damping elastomer of the first damper components is softer, the damping elastomer of the second damper components
It is harder, the damping property of integral vibration damping device can be made further to be optimized.
