Abstract
The utility model provides a reciprocating type dust sealing washer, which comprises a butadiene nitrile rubber dust sealing washer and a skeleton arranged at the inner part thereof, and a lip opening arranged on the inner wall of the dust sealing washer. The reciprocating type dust sealing washer is characterized in that the contact site of the dust sealing washer lip opening and the piston rod of a shock absorber has a small planar structure, and the dust sealing washer lip opening comprises a main lip opening and an upwarping type second lip opening. The reciprocating type dust sealing washer can improve the sealing reliability and prolong the service life of the shock absorber, and can prevent dust and sands in the air entering a shock absorber oil seal.
Description
Technical field
The utility model relates to a kind of component of automobile industry, is mainly used on automobile, the motorcycle vibration absorber, specifically a kind of reciprocating type envelope konisphere.
Background technique
Therefore automobile, the motorcycle phenomenon of can jolting in the process of moving, needs vibration damper.As shown in Figure 1, existing envelope konisphere product has only dust excluder lips one, and lip is little circular arc, is that line contacts with piston rod, lip is easy to wear, and behind the ageing of rubber, it is big that the lip size becomes, dustproof weak effect, the silt dust enters oil sealing, causes the wearing and tearing of oil sealing, causes the early stage leakage of oil of oil sealing.
How to design a kind of reciprocating type envelope konisphere, improve its sealing reliability, prevent that dust and the silt in the atmosphere from entering in the vibration damper oil sealing, prolong the working life of vibration damper, this is the technical problem that needs to be resolved hurrily at present.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, and a kind of reciprocating type envelope konisphere is provided, and improves its sealing reliability, prevents that dust and the silt in the atmosphere from entering in the vibration damper oil sealing, prolongs the working life of vibration damper.
The purpose of this utility model is achieved by the following technical solution:
A kind of reciprocating type envelope konisphere comprises nitrile rubber envelope konisphere and inner skeleton, and envelope konisphere inwall is provided with lip, and it is characterized in that: described envelope konisphere lip and piston lever of reducer contact position are facet formula structure.
In technique scheme, also have following technical characteristics: described envelope konisphere lip comprises the main lip and second lip.
In technique scheme, also have following technical characteristics: the described second lip structure is a bending upwards type.
In technique scheme, also have following technical characteristics: the described main lip back side is provided with annular groove, and annular groove is embedded in annular spring.The envelope dirt effect that main lip is remained valid, main lip wearing and tearing back annular spring is compensated for the main lip power of holding tightly.
In technique scheme, also have following technical characteristics: described annular spring is a stainless steel spring.
Compared with prior art, advantage of the present utility model and good effect are:
1, the utility model envelope konisphere lip position is designed to facet formula structure, is that face contacts good airproof performance with the piston lever of reducer contact position.
2, the utility model increases by second lip, the second lip structure is a bending upwards type, the first road lip is envelope dust and silt, the second road lip is that the dust that has entered can accumulate in the second road lip, dust and silt are not entered in the vibration damper oil sealing, crucial effect has been played in wearing and tearing to the oil sealing of vibration damper, and the vibration damper life-span is improved.
3, the utility model increases stainless steel spring in the outside of main lip, the envelope dirt effect that instigator's lip is remained valid, and lip wearing and tearing rear spring is compensated to the lip power of holding tightly, makes this envelope konisphere life-span and vibration damper synchronous, reaches domestic and international advanced level.
4, it is simple in structure, and is easy to process.
