Description
Technical field
The utility model belongs to technical field of automobile engine, specifically, relates to a kind of automobile engine cylinder head casing sealing gasket that seals between cylinder head cover and the cylinder cap that is applicable to.
Background technique
Between the cylinder cap of motor car engine and cylinder head cover cylinder cover hood seal gasket can be set, the sealing that purpose is to strengthen is between the two revealed with the machine oil that prevents the lubricated usefulness in cylinder cap and the cylinder head cover.At present, the engine cylinder cover hood seal gasket adopts the plane sealing mode more, that is to say that engine cylinder cover hood seal gasket and cylinder cap phase-contact surface are plane contact, engine cylinder cover hood seal gasket and cylinder head cover surface of contact also are plane contact, also have on cylinder cover of engine, to design seal groove is arranged, the engine cylinder cover hood seal gasket is provided with the raised line that adapts with seal groove, to increase the destabilizing factor that sealing overcomes plane sealing.Owing to be subjected to the structural limitations of cylinder cap itself; for example for the sort of structure more complicated; be subjected to the restriction of its structure middle chamber outer ring or oil duct outer ring wall thickness, be not suitable for being provided with seal groove on cylinder cap, so common meeting is provided with sealed muscle on contacted of engine cylinder cover hood seal gasket and cylinder cap.But owing in the market the performance requirement of motor is improved constantly, make that the requirement for sealing also improves constantly, existing design is difficult to guarantee now the high standard to motor.Can occur the situation that lubricating oil is revealed in the practical application.
In addition; in order to finish processing to engine cylinder cover inside; the capital is provided with technology groove in the left and right sides of cylinder cap; this technology groove only is the needs for processing technology; the performance to cylinder cap does not work; therefore cylinder head cover and cylinder cap being installed to a time-out just need block up described technology groove; usually can adopt independent aluminum semicircle plug; that is to say technology groove to be filled and led up again and seal by sealing gasket by aluminum semicircle plug; tend in the said structure because of combining between semicircle plug and cylinder cap and the sealing gasket not tight; leakage of oil occurs the easiliest, reliability is relatively poor.
The model utility content
For solving above technical problem, the purpose of this utility model is to provide a kind of sealing that can effectively strengthen between cylinder cap and the cylinder head cover, has especially strengthened the automobile engine cylinder head casing sealing gasket of sealing between auxiliary hole place cylinder cap, semicircle plug, cylinder head cover.
The technical solution of the utility model is as follows:
A kind of automobile engine cylinder head casing sealing gasket, comprise sealing gasket body, the semicircle plug made by rubber, described semicircle plug is arranged on the both sides of sealing gasket body, the cross section of described sealing gasket body is "T"-shaped, form the close encapsulation muscle around the upper surface of described sealing gasket body, be provided with the adjustment groove near the sealing gasket body of sealing muscle both sides; Described semicircle plug and the sealing gasket body structure that is one of the forming, described semicircle plug middle part forms half slot, and the internal surface of this half slot is inlaid with skeleton.
Make the distortion of sealed muscle even by the adjustment groove when adopting above-mentioned structure purpose that increase to adjust groove in the sealed muscle both sides to be cylinder cap and cylinder head cover compressed, adjust the position that groove is equivalent to reserve an adjustment, avoid the inequality of sealed muscle place because of distortion, make and may cause the inhomogeneous of impacting force compressing the leakage of oil at place.Semicircle plug and sealing gasket body are integral, just between semicircle plug and sealing gasket body, formed the state of sealing fully, can not form sealing contact surface by between, effectively avoid independent use semicircle plug to occur to occur the situation of leakage of oil between the two.At semicircle plug middle part half slot is set in addition, the centre is provided with metal frame when guaranteeing that the semicircle plug has certain intensity, has saved material, has alleviated weight, also utilize the good advantage of rubber seal performance, avoid the bad shortcoming of original employing aluminum semicircle plug rigidity contact seal effect.
The outer rim of described semicircle plug is provided with semicircular raised line, and this raised line is positioned at the outside of described sealed muscle.
Outer rim at the semicircle plug is provided with semicircular raised line, and this raised line is inboard to fit with the technology groove outer wall, is the equal of that technology groove has been placed in the formed seal groove of two raised lines, has increased a seal point again, has improved sealing.
Be provided with two semicircle plugs in described sealing gasket body left side, the right side is provided with a semicircle plug.The position of determining the semicircle plug according to the particular location and the quantity of cylinder cap technology groove.
Upper surface around described semicircle plug and sealing gasket body forms a pair of close encapsulation muscle that is parallel to each other, and the cross section of every sealed muscle is triangle.Adopt the sealed muscle of pair of parallel can strengthen sealing effect, it is the line contact that the triangle of the cross section of sealed muscle employing simultaneously makes itself and contacting of cylinder head cover, has strengthened impacting force between the two, has improved sealing.
Beneficial effect: the utility model is simple in structure, easy to process, can effectively strengthen the sealing between cylinder cap and the cylinder head cover, especially strengthened the automobile engine cylinder head casing sealing gasket of sealing between auxiliary hole place cylinder cap, semicircle plug, cylinder head cover.
