Description
Technical field
The utility model relates to a kind of vibration damper, especially a kind of vibration damper with yielding rubber.
Background technique
Vibration damper is an important component part of automobile suspension system, the concussion when it is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, though the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.
After the road of injustice travels or carries certain article; vibration damper exceeds high capacity through regular meeting; and the vibration damper upper piston can be subjected to the tractive of the effect generation limit position of piston rod; at this moment; piston will bump with inboard wall of cylinder block; even might cause the impaired of piston and inboard wall of cylinder block contact position, thereby influence the normal function of piston.The damage situations of piston is decided on angle and the dynamics of piston and inboard wall of cylinder block interphase interaction.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, and can protect the vibration damper of piston band yielding rubber of security work when limit position.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of vibration damper with yielding rubber, comprise cylinder body, be provided with piston in the cylinder body, piston is provided with and extends to the outer piston rod of cylinder body, spring seat is also fixedly arranged on the piston rod, also be arranged with spring on the cylinder body, the axial two ends of spring are connected with cylinder body with spring seat respectively, offer the through hole that wears usefulness for piston rod on the described yielding rubber, this yielding rubber is positioned between cylinder body and spring seat, be provided with locating slot towards the position of spring seat on the yielding rubber, spring seat is provided with the positioning block corresponding with locating slot, be provided with the receiving groove that partly holds for yielding rubber on the cylinder body towards the position of yielding rubber, yielding rubber along piston rod to length be 10 ~ 50mm.
Preferably be set to: described yielding rubber along piston rod to length be 30mm.
Further be set to: the position corresponding with receiving groove is cone structure on the described yielding rubber, and the little cephalic par of this cone structure is towards the receiving groove setting.
Further be set to: the cross section of described locating slot is circle or polygonal.
Preferably be set to: the cross section of described locating slot is for circular.
Further be set to: described spring seat is installed on the piston rod apart from the distal-most end of cylinder body, also is provided with installing ring on this spring seat.
Further be set to: the inner ring of described installing ring is provided with rubber pad again.
The beneficial effects of the utility model are: yielding rubber is because be that rubber material is made, so it has the effect of bumper and absorbing shock, when piston rod stressed when excessive, spring seat can impact towards cylinder body, at this moment, the yielding rubber that is positioned between spring seat and cylinder body will be brought into play the effect of bumper and absorbing shock, thereby avoids cylinder body, piston, piston rod or spring seat to damage.Simultaneously, be shifted in long-term impact in the past for fear of yielding rubber, so at yielding rubber and spring seat, and be respectively equipped with for the structure of locating between yielding rubber and cylinder body.Certainly, more stable in order to locate, so it is the structure of locating slot can adopt circle or polygonal on the yielding rubber, preferably circular.If with circular, when rotation around piston rod took place yielding rubber, positioning block also can enter the locating slot on the yielding rubber exactly on the spring seat.Fixed installation between jacket casing and vehicle frame can be convenient to regulate by installing ring, and noise in the using process can be reduced by rubber pad.
