Abstract
An engine cylinder cover seal gasket is in nail form with large upper part and small lower part, which is characterized in that the top of the seal gasket is provided with an arc top seal line; optionally, the bottom of the seal gasket is provided with an arc bottom seal line, two sides of the seal gasket adaptive to a cylinder cover notch are respectively provided with a boss group of long arc form; since the seal gasket is made from pure rubber with tearing resistant component, the utility model can prevent the gasket from being broken under press and prevent the sealing lubricant from failure after the connection of two rigid connectors as the cylinder cover and the cylinder cap; the arc seal lines are added at the upper and the lower surfaces of the seal gasket, and two sides are added with boss structure, while the bosses at two sides can confirm interference fit between the gasket and the cover groove, thus being beneficial for assembly and seal; and the arc seal lines at upper and lower can prevent lubricant from leaking from the cylinder cap.
Description
Technical field
The utility model relates to a kind of cylinder head cover sealing gasket of motor, realizes the sealing between engine bonnet and the cylinder cap.
Background technique
At present, the requirement to motor on the automobile is more and more higher, and it is quite important wherein to seal this part, influences engine performance first, increases oil consumption; Influence outward appearance first, do not satisfy environmental protection; Also reduced satisfaction of customers virtually.The most rubber materials that adopt of sealing between available engine cylinder head cover and the cylinder cap are realized.Material selects improper or improper seepage oil or the pad of all can causing of structure occurred by situations such as pressure breaks.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the cylinder head cover sealing gasket at available engine to provide a kind of engine cylinder cover hood seal gasket.To guarantee the reliable sealing between cylinder head cover and the cylinder cap.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of engine cylinder cover hood seal gasket, described sealing gasket sectional shape is the nail shape that top is big, the bottom is little, it is characterized in that: circular arc end sealing line is set on the top of sealing gasket.Circular arc bottom end seal line can also be set in the bottom of sealing gasket.Can also uniform one group of boss be set in the both sides that sealing gasket adapts to the cylinder head cover draw-in groove.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 rigid connectors of cylinder head cover and cylinder cap are 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 cover 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 the cylinder head cover and cylinder head under the high-performance, has improved the physical life of product, is beneficial to assembling simultaneously, has improved efficiency of assembling, has reduced labor intensity.
Below with reference to accompanying drawing and example, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is the utility model sealing gasket cross-sectional view.
Among the figure: 1. end sealing line, 2. left boss, 3. bottom end seal line, 4. right boss.
Embodiment
As shown in Figure 1, a kind of engine cylinder cover hood seal gasket, described sealing gasket sectional shape are the nail shapes that top is big, the bottom is little, and circular arc end sealing line 1 is set on the top of sealing gasket.Circular arc bottom end seal line 3 can also be set in the bottom of sealing gasket.Uniform one group of left side boss 2 and right boss 4 can also be set in the both sides that sealing gasket adapts to the cylinder head cover draw-in groove.Described left and right boss is a long arc shape.
Described end sealing line and bottom end seal line can also be more than two.
Sealing gasket adopts the gum material, and material internal adds the chemical composition of modification to increase the intensity of its tear-proof simultaneously.
