Abstract
The utility model discloses a laminated cushion of a metal cylinder; and the laminated cushion of the metal cylinder comprises a cushion body and an air cylinder hole arranged on the cushion body; the cushion body is formed by pressing an upper metal plate layer, a middle metal plate layer and a lower metal plate layer; a first arc-shaped crinkle is pressed on the middle metal plate layer along the circumference of the air cylinder hole; the laminated cushion of a metal cylinder is characterized by arranging a second arc-shaped crinkle on the upper metal plate layer along the circumference of the first arc-shaped crinkle. The utility model has beneficial effects as follows: as the plate layers of the cylinder cushion are much richer in elasticity, the stress supported by the cushion; therefore, the sealing performance and the durability of the cylinder port are improved, and thus the operation reliability of an engine is also enhanced.
Description
Technical field
The utility model relates to cylinder gasket construction field, is specifically related to a kind of lamination type Metallilc gasket.
Background technique
As everyone knows, cylinder gasket is the important spare part that is used for connecting cylinder head and cylinder block, and cylinder gasket needs reliable sealing high-temperature fuel gas, lubricant oil and cooling liquid, the good and bad performance that directly influences motor of cylinder gasket.
Raising along with emission request and power; The pressure of explosion of motor is brought up to more than the 16Mpa by initial 12Mpa; Existing lamination cylinder gasket cylinder oral area position is employed in metallic intermediate layer plate compacting and seals ripple together and carry out gas seal, and leak rate is higher when adopting the pad of this structure on high detonation pressure high-power diesel engine, to use.
The model utility content
The purpose of the utility model is the deficiency that exists to above-mentioned existing technology, and a kind of novel lamination type Metallilc gasket is provided, to improve cylinder gasket cylinder oral area position sealing.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of lamination type Metallilc gasket; Comprise pad and cylinder-bore provided thereon; Said pad is formed by upper strata sheet metal, middle level sheet metal and the compacting of lower metal plate; Said middle level sheet metal is being suppressed with the first arc ripple along the cylinder-bore periphery, its unique distinction is that said upper strata sheet metal is being provided with the second arc ripple along the said first arc ripple periphery.
Said arc ripple is that the bottom of on sheet metal, suppressing is the groove of arc.
The said second arc ripple is identical with the said first arc bellows-shaped, arcuate directions is opposite.
The beneficial effect of the utility model is: because said middle level sheet metal is being suppressed with the first arc ripple along the cylinder-bore periphery; Said upper strata sheet metal is being provided with the second arc ripple along the said first arc ripple periphery; The first arc ripple matches with the second arc ripple, makes more high resilience between the laminate, and the pressure distribution that pad bore is more even; Thereby improved seal with annular groove property and durability, and then also improved the engine operation reliability.
Description of drawings
Fig. 1 is the lamination type Metallilc gasket structural representation of the utility model;
Fig. 2 is first embodiment's cylinder-bore A-A part section structural representation of Fig. 1;
In Fig. 1-Fig. 2,1, the upper strata sheet metal, 2, the middle level sheet metal, 3, the lower metal plate, 4, the first arc ripple, 5, the second arc ripple, 6, cylinder-bore.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As depicted in figs. 1 and 2; A kind of lamination type Metallilc gasket; Comprise pad and cylinder-bore 6 provided thereon; Said pad is formed by upper strata sheet metal 1, middle level sheet metal 2 and 3 compactings of lower metal plate, and said middle level sheet metal 2 is being suppressed with the first arc ripple 4 along cylinder-bore 6 peripheries, and said upper strata sheet metal 1 is being provided with the second arc ripple 5 along the said first arc ripple, 4 peripheries.
The said second arc ripple 5 is identical with the said first arc ripple, 4 shapes, arcuate directions is opposite.
The above is merely the preferred embodiments of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (2)
