Description
Technical field
The utility model relates to automobile technical field, refers in particular to a kind of high strength air-valve guide-bar oil seal.
Background technique
In recent years, along with the development of automotive industry, the acceleration control overflow of people to car engine motor speed is more and more higher, common motor cannot meet the pursuit that people accelerate car speed to control, existing plain edition air-valve guide-bar oil seal pressurization friendship rate is lower, complex structure, use and inconvenience is installed, for the acceleration improving car speed controls, along with the increase of oil-air pressure in piston cylinder, improve air input of engine by air by engine turbine supercharging, thus improve power and the moment of torsion of motor, improve the operational efficiency of automobile.Therefore, design a kind of air-valve guide-bar oil seal that can solve the problem to be necessary.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of high strength air-valve guide-bar oil seal of energy-saving and cost-reducing, long service life.
For achieving the above object, technological scheme provided by the utility model is: a kind of high strength air-valve guide-bar oil seal, it includes seal, skeleton, spring, sealing lip, back pressure lip, wherein, seal upper inside wall is provided with sealing lip, sealed body cavity bottom is provided with protruding back pressure lip, spring fitting is outside seal, the outer middle side part of seal is provided with concavity draw-in groove, concavity draw-in groove adopts by lower inside top arc-shaped transition from notch to bottom land, skeleton top edge is provided with the supporting position of arc, this supporting position intercalation is in draw-in groove, seal lower outside is bonded in skeleton and forms sealing, seal lower inside is provided with concavo-convex stiffening rib, and stiffening rib is the double wedge shape of concavo-convex corrugated or the regular distribution of then not advising.
Described sealing lip, back pressure lip integrally extend shaping by seal madial wall, and wherein, back pressure lip extended length is greater than sealing lip extended length.
The utility model has the advantage of:
The first, the present invention is by strengthening the support strength of Sealing rubber body and adopting arcuate structure, thus greatly improves sealing and the life-span of Sealing.
The second, the present invention is by adding frame strength, makes skeleton be not easy distortion in production processes such as transhipment and sulfuration pretreatments, thus reduces the reject rate of the later product of sulfuration.
Three, the present invention is by adding frame strength, makes Sealing be not easy distortion in transhipment and installation process, ensure that the quality of Sealing.
Four, rubber body raw material, its price is about 50 times of framework metal material, and the present invention, by decreasing the use of rubber, effectively reduces cost.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with institute's drawings attached, the utility model is described in further detail, preferred embodiment of the present utility model is: see accompanying drawing 1, high strength air-valve guide-bar oil seal described in the present embodiment includes seal 1, skeleton 2, spring 3, sealing lip 4, back pressure lip 5, wherein, seal 1 upper inside wall is provided with sealing lip 4, seal 1 inner chamber bottom is provided with protruding back pressure lip 5, sealing lip 4, back pressure lip 5 integrally extend shaping by seal 1 madial wall, wherein, back pressure lip 5 extended length is greater than sealing lip 4 extended length; Spring 3 is arranged on outside seal 1, the outer middle side part of seal 1 is provided with concavity draw-in groove 7, concavity draw-in groove 7 adopts by lower inside top arc-shaped transition from notch to bottom land, skeleton 2 top edge is provided with the supporting position 6 of arc, this supporting position 6 intercalation is in draw-in groove 7, and seal 1 lower outside is bonded in skeleton 2 and forms sealing; Seal 1 lower inside is provided with concavo-convex stiffening rib 8, and stiffening rib 8 is the double wedge shape of concavo-convex corrugated or the regular distribution of then not advising.Sealing lip canned motor upper end engine oil; back pressure lip can protect the lubricating status of sealing lip; prevent from turbosupercharging in motor from forming high-pressure oil gas the lubricant oil of sealed lip is blown away; form lack of lubrication; leakage of oil amount is caused to reduce; cause valve guide bushing to sinter wearing and tearing, thus cause valve stem can not lubricate closedown or open and leak gas.Ensure that the smooth and easy motion of valve stem, both saved energy and reduce the cost, turn improve the working life of oil sealing simultaneously.
The embodiment of the above is only the preferred embodiment of the utility model, not limits practical range of the present utility model with this, therefore the change that all shapes according to the utility model, principle are done, all should be encompassed in protection domain of the present utility model.
