In the figure: 1. a metal carrier; 11. a joint; 12. bolt holes; 13. positioning holes; 2. a rubber gasket; 21. a first sealing lip; 22. a second sealing lip; 23. a third sealing lip; 24. a sealing lip IV; 25. the sealing lip is connected with the rib.
Detailed Description
The present utility model will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1-4, the utility model provides a composite sealing gasket of an oil pan, which comprises a metal carrier 1 and a rubber sealing gasket 2, wherein the metal carrier 1 is sequentially connected by four L-shaped sections, and both ends of each section are provided with convex-concave structures to jointly form four joints 11; the rubber sealing gasket 2 is provided with a first sealing lip 21, a second sealing lip 22, a third sealing lip 23 and a fourth sealing lip 24 on two end surfaces, the sealing effect can be enhanced by the design, and the sealing lips are designed on the inner side of the metal carrier of the oil pan sealing gasket, so that the risk of engine oil leakage can be greatly reduced; the rubber gasket 2 is provided inside the metal carrier 1.
A plurality of sealing lip connecting ribs 25 are arranged between the two sealing lip I21 and the sealing lip II 22 and between the sealing lip III 23 and the sealing lip IV 24 on the same end face of the rubber sealing gasket 2; on the one hand, the sealing lip has stronger lodging resistance, on the other hand, after the inner sealing lip fails, the structure can control engine oil in a rectangular area formed by two sealing lips and connecting ribs at two sides of a leakage point, so that the engine oil is prevented from diffusing between the slots between the two sealing lips, and even if the sealing lips leak, the engine oil can leak only when the two sealing lips leak and the leakage positions are located between two adjacent connecting ribs; if no connecting ribs are arranged, no matter what position is, as long as two sealing lips are provided with leakage points, engine oil can be leaked to the outside of the oil pan through the leakage points and the slots. One sealing lip can be designed on each of the inner side and the outer side of the metal carrier 1, and when the first sealing lip fails, the second sealing lip can be used for sealing in a supplementary way.
Two positioning holes 13 are formed in each of the four sections of the metal carrier 1.
Four sections of the metal carrier 1 are respectively provided with a plurality of bolt holes 12, and bolts of the oil pan pass through the bolt holes to be fixed on the cylinder body when the oil pan is installed.
The metal carrier 1 adopts aluminum magnesium alloy with the thickness of 2mm, and has the advantages of light weight, high bearing capacity and easy processing.
The rubber gasket 2 is made of AEM rubber, and has good environmental stress cracking resistance.
The rubber sealing gasket 2 is adhered to the metal carrier 1 through an integrally formed vulcanization process, and before rubber adhesion, four metal carrier sections can be installed on a tool through two positioning holes, so that the position of the oil pan composite sealing gasket is improved; in addition, due to the physical characteristics of rubber and the sectional design of the metal carrier, the composite sealing gasket finished product of the oil pan has good deformation resistance and fracture resistance in the transportation and assembly processes.
The utility model solves the problem of difficult processing of the large-sized metal sealing gasket and the problems of breakage and deformation of the sealing gasket finished product in the transportation and assembly processes, and has the advantages of high bearing, high reliability, easy production, easy transportation, easy assembly, easy disassembly and the like compared with the traditional oil pan sealing gasket.
The above-described embodiments of the utility model are intended to be examples only, and not to be limiting, and all changes that come within the scope of the utility model or equivalents thereto are intended to be embraced thereby.
