Abstract
The utility model provides a reciprocal oil blanket of board-like, including butyl cyanide rubber oil blanket and inside skeleton, butyl cyanide rubber oil blanket inner wall sets up main lip, support lip and vice lip, the main lip back sets up the annular groove, the embedded ring spring of annular groove, its characteristics are: the back of the auxiliary lip is provided with an annular groove, an annular spring is embedded into the annular groove, so that the auxiliary lip keeps an effective dust sealing effect, and after the auxiliary lip is abraded, the holding force of the annular spring for the auxiliary lip is compensated. The oil level side of the nitrile butadiene rubber oil seal is provided with a radial sealing lip, the radial sealing lip plays a role in sealing air and returning oil to the shock absorber, oil leakage in the shock absorber is avoided, the service life level of the shock absorber is improved, and the service life of the oil seal is synchronous with that of the shock absorber.
Description
Technical field
The utility model relates to a kind of component of automobile industry, is mainly used on the automobile absorber, specifically a kind of board-like reciprocating oil seal.
Background technique
Therefore the automobile phenomenon of can jolting in the process of moving, needs vibration damper.As shown in Figure 1, size becomes big behind the existing reciprocating oil seal product lip ageing of rubber, the secondary lip power of holding tightly can not get compensation, dustproof weak effect, silt, dust enter oil sealing and easily cause the early stage leakage of oil of oil sealing, and existing procucts effect in the inflation vibration damper is poor in addition, because there is not the radial seal lip, institute's qi of chong channel ascending adversely body can not get effective sealing, and gas is easily revealed.
How to design a kind of reciprocating oil seal, 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.In addition, also will be fit to inflate in the vibration damper use, 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 board-like reciprocating oil seal is provided, and improves its sealing reliability, prevents that dust and silt from entering in the vibration damper oil sealing, avoids the oil seepage in the vibration damper, prolongs the working life of vibration damper.In addition, also to be fit to inflate in the vibration damper use.
The purpose of this utility model is achieved by the following technical solution:
A kind of board-like reciprocating oil seal, comprise nitrile rubber oil sealing and inner skeleton, nitrile rubber oil sealing inwall is provided with main lip, supports lip and secondary lip, the described main lip back side is provided with annular groove, annular groove is embedded in annular spring, it is characterized in that: the described secondary lip back side is provided with annular groove, and annular groove is embedded in annular spring, the envelope dirt effect that secondary lip is remained valid, secondary lip wearing and tearing back annular spring is compensated for the secondary lip power of holding tightly.
In technique scheme, also have following technical characteristics: in technique scheme, also have following technical characteristics: the pasta side of described nitrile rubber oil sealing is provided with the radial seal lip.
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 secondary lip back side of the board-like reciprocating oil seal of the utility model is provided with annular groove, annular groove is embedded in annular spring, the envelope dirt effect that secondary lip is remained valid, secondary lip wearing and tearing back annular spring is compensated for the secondary lip power of holding tightly, prevents that dust in the atmosphere and silt etc. from entering in the oil sealing.
2, the utility model is provided with the radial seal lip in the pasta side of nitrile rubber oil sealing, and the radial seal lip plays envelope gas and vibration damper oil return effect, avoids the oil seepage in the vibration damper, and the life level of vibration damper is improved, and makes the life-span of oil sealing and vibration damper synchronous.Be fit to use in the inflation vibration damper.
3, it is simple in structure, and is easy to process.
Description of drawings
Fig. 1 is the partial sectional view of existing reciprocating oil seal;
Fig. 2 is the partial sectional view of the board-like reciprocating oil seal of the utility model;
Fig. 3 is the sectional arrangement drawing of the board-like reciprocating oil seal of the utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 2, shown in Figure 3, a kind of board-like reciprocating oil seal comprises nitrile rubber oil sealing 5 and inner skeleton 6, and nitrile rubber oil sealing 5 inwalls are provided with main lip 1, support lip 2 and secondary lip 3.Described main lip 1 back side is provided with annular groove, and annular groove is embedded in annular spring 8; Described secondary lip 3 back sides are provided with annular groove, and annular groove is embedded in ring stainless steel spring 4, the envelope dirt effect that major and minor lip is remained valid, and major and minor lip wearing and tearing back annular spring 8,4 is compensated for the major and minor lip power of holding tightly.
Pasta side at nitrile rubber oil sealing 5 is provided with radial seal lip 7, and radial seal lip 7 plays envelope gas and vibration damper oil return effect, avoids the oil seepage in the vibration damper, and the life level of vibration damper is improved, and makes the life-span of oil sealing and vibration damper synchronous.
Among Fig. 3, also comprise piston rod 9, guider 10, inner core 11, urceolus 12.
The above, it only is preferred embodiment of the present utility model, be not to be the restriction of the utility model being made other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
