Abstract
An engine cylinder head cover sealing gasket is characterized in that the cross section of the sealing gasket is in the shape of a big-end-up nail, a circular-arc top sealing line is arranged at the top end of the sealing gasket, a circular-arc bottom sealing line can be arranged at the bottom end of the sealing gasket, bosses in a group are uniformly arranged on two sides of the sealing gasket matched with a cylinder head clamping groove, and the cross sections of the bosses are long arc-shaped. The engine cylinder head cover sealing gasket has the advantages that the circular-arc sealing lines are added on the upper surface and the lower surface of the sealing gasket, the boss structures are added on the two sides of the sealing gasket, interference fit between the sealing gasket and the cylinder head clamping groove is guaranteed by the bosses on the two sides of the sealing gasket so that assembly and sealing can be realized favorably, and further the circular-arc top sealing line and the circular-arc bottom sealing line prevent lubricating oil leaking from a cylinder head. Accordingly, reliable sealing between a cylinder cover and the cylinder head is guaranteed on the premise of high performance, product service life is prolonged, assembly is completed conveniently, assembly efficiency is increased, and labor intensity is decreased.
Description
Technical field
The utility model relates to motor car engine, promptly a kind of engine air cylinder cap sealing gasket, and it realizes the sealing between cylinder cover and the cylinder cap.
Background technique
At present, automobile is more and more higher to the requirement of motor, and it is quite important wherein to seal this part, seals bad influence first engine performance, increase oil consumption; Second influence outward appearance, do not satisfy environmental protection requirement; Also reduced satisfaction of customers virtually.Sealing great majority between available engine cylinder cover and the cylinder cap adopt rubber material to realize that the surface of upper and lower, left and right is the plane, and structure is single, and is not too reasonable, often causes seepage oil or pad to be occurred by situations such as pressure breaks.
Summary of the invention
The purpose of this utility model is the structural deficiency that exists in the valve mechanism cover sealing gasket at available engine to provide a kind of engine air cylinder cap sealing gasket.To guarantee the reliable sealing between cylinder cover and the cylinder cap.
This engine air cylinder cap sealing gasket, its sealing gasket sectional shape is the nail shape that top is big, the bottom is little, it is characterized in that, is provided with circular arc end sealing line on the top of sealing gasket.Circular arc bottom end seal line can also be set in the bottom of sealing gasket.One group of boss of even layout can also be set in the both sides that sealing gasket adapts to the cylinder cap draw-in groove.The cross section of described boss is a long arc shape.
Good effect of the present utility model:
1, sealing gasket adopts the gum material, and material internal adds the composition of tear-proof simultaneously, prevent that these two parts of cylinder cover and cylinder cap are rigidly connected after, cause pad by pressure break, the disabler of sealing lubricating oil.
2, the circular arc potted line that increases in the sealing gasket upper and lower surface, both sides have increased boss structure, and the boss of both sides guarantees that between pad and the cylinder cap groove be interference fit, is beneficial to assembling, simultaneously also be beneficial to sealing, circular arc potted line up and down is to guarantee that lubricant oil does not ooze out in cylinder cap.
Therefore, the utility model has guaranteed the reliable sealing between high-performance lower cylinder cover and the cylinder cap, is beneficial to assembling simultaneously the working life of having improved product, has improved efficiency of assembling, has reduced labor intensity.
Description of drawings
Fig. 1 is the utility model sealing gasket cross-sectional view.
Among the figure, 1, circular arc end sealing line, 2, left boss, 3, circular arc bottom end seal line, 4, right boss.
Embodiment
Below with reference to accompanying drawing and example, the utility model is carried out comparatively detailed explanation.
As shown in Figure 1, this engine air cylinder cap sealing gasket, its sectional shape is the nail shape that top is big, the bottom is little, be provided with circular arc end sealing line 1 on the top of sealing gasket, be provided with circular arc bottom end seal line 3 in the bottom of sealing gasket, be provided with the one group of left side boss 2 and the right boss 4 of even layout in the both sides that sealing gasket adapts to the cylinder cap draw-in groove.The cross section of described left and right sides boss is a long arc shape.
Described end sealing line and bottom end seal line can also be two or three.
Sealing gasket adopts the gum material, and the chemical composition of the modification of material internal interpolation simultaneously increases the intensity of its tear-proof.
