Abstract
The invention discloses a sealing gasket of a cylinder cover hood for an engine, which is used for reliable sealing between a cylinder cover with an auxiliary hole and the cylinder cover hood. The sealing gasket and a semi-circular boss are integrated, the semi-circular boss is a rubber solid, the section width of the semi-circular boss is gradually increased from top to bottom, the outer edge of the bottom of the semi-circular boss is provided with two raised lines, and a closed sealing rib is formed around the upper surface and the bottom of the sealing gasket respectively. The sealing gasket has a simple structure, saves cost, is easy to process, and convenient to install, and can effectively enhance the sealing between the cylinder cover with the auxiliary hole and the cylinder cover hood.
Description
Technical field
The invention belongs to the technology of gasoline engine field, be specifically related to a kind of sealing technique of motor.
Background technique
Cylinder head cover sealing gasket that can the design rubber material between the cylinder cap of motor car engine and cylinder cover, purpose are to strengthen between the two sealing to prevent the leakage of cylinder cap and cylinder cover inner engine oil.But because the requirement of engine cylinder cover structure, in the inner processing of cylinder cap, can stay the auxiliary hole of two semicircles, therefore just need block up described auxiliary hole when cylinder cover and cylinder cap install to a time-out in cylinder cap one side.As shown in Figure 1, existing method is to seal by valve mechanism cover sealing gasket 2 with cylinder head cover 1 by the cylinder cap 3 that has auxiliary hole 31, and the valve mechanism cover sealing gasket has semicircle boss 21, fills up the auxiliary hole on the cylinder cap.As Fig. 3 is the sectional view of the A-A of valve mechanism cover sealing gasket upper semi-circle boss, form half slot 214 at semicircle boss middle part, be inlaid with metal frame 215 in half slot, the semicircle boss that is surrounded by metal frame has been filled the auxiliary hole of cylinder cap on the one hand, has played the effect of spacing support on the other hand.Because the raising of engine performance is also more and more higher to the requirement of sealing, this valve mechanism cover sealing gasket of semicircle boss that has is when being assembled between cylinder cap and the cylinder cover, because the existence of metal frame, cause oil leakage at the situation lower semi-circle boss of same bolt coupling mechanism force and the different meeting of compressibility of rubber body sealing gasket, the half-turn boss is not when mounted owing to there is located lateral to be easy on the other hand, be easy to occur oil leakage phenomenon like this, reliability is relatively poor.
Summary of the invention
For solving above technical problem, the object of the present invention is to provide a kind of engine air cylinder cap sealing gasket that can effectively strengthen sealing between the cylinder cap that has auxiliary hole and the cylinder head cover.
Technological scheme of the present invention is as follows:
A kind of valve mechanism cover sealing gasket of motor, described sealing gasket are installed between the cylinder cap and cylinder head cover that has auxiliary hole, and described sealing gasket is having the semicircle boss consistent with the auxiliary hole shape with corresponding local one-body molded in the auxiliary hole position of cylinder cap.Described semicircle boss is a solid body, and the increase gradually from top to bottom of its cross-sectional width has strengthened the area of contact of rubber gasket and cylinder cap semicircle orifice, makes stressed more evenly, has guaranteed the reliability of sealing.Semicircle boss and sealing gasket body all adopt rubber material to make, and from designing the reliability while that has guaranteed sealing, have simplified processing technology again, have alleviated weight, have reduced cost.
Further, root edge place, both sides in described semicircle boss cross section has downward raised line respectively, the inboard of this raised line and the outer wall of auxiliary hole fit, auxiliary hole is clipped in the formed seal groove of two raised lines, when having increased by two seal points like this, prevent that also the semicircle boss from being adorned askew and leakage of oil that cause.
In addition, be provided with first sealed muscle of at least one sealing, further be provided with second sealed muscle of sealing, can strengthen sealing effect in proper order around the upper surface of sealing gasket around the bottom surface of whole sealing gasket.
Be that cross section with first and second sealed muscles is provided with promising triangle preferably, it is contacted with the cylinder cap face to the line contact, can strengthen impacting force between the two, improve sealing.
Good effect of the present invention is:
The present invention is simple in structure, reduces cost, and is easy to processing, and is easy for installation, can effectively strengthen the sealing that has between auxiliary hole cylinder cap and the cylinder cover.

Among the figure: 1-valve mechanism cover, 2-sealing gasket, 21-semicircle boss, 3-cylinder cap, 31-auxiliary hole, 211-second sealed muscle, 212 –, first sealed muscle, 213-raised line, 214-half slot, 215-metal frame.
Embodiment
As Fig. 2 and shown in Figure 4, the semicircle boss 21 of this engine air cylinder cap sealing gasket is one-body molded with sealing gasket 2, and semicircle boss 21 and sealing gasket all adopt rubber material to make.Semicircle boss 21 is rubber solid bodys, cross-sectional width increase gradually from top to bottom, and semicircle boss outer rim is provided with two semi-circular raised lines 213.Root edge place, both sides in semicircle boss 21 cross sections has downward raised line 213 respectively, and the outer wall of the inboard of this raised line and auxiliary hole 31 fits, and auxiliary hole 31 is clipped in two raised lines, the 213 formed seal grooves.Be provided with first sealed muscle 212 of two parallel seals around the bottom surface of whole sealing gasket 2, be provided with second sealed muscle 211 of a sealing simultaneously around the upper surface of sealing gasket 2, the cross section of this first and second sealed muscle 212,211 is a triangle.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the intent of the present invention also comprises these changes and is out of shape interior.
