[0003] In the prior art, the oil pan is usually sealed by applying sealant on the contact surface between the oil pan and the engine body. However, this sealing method has high requirements on the sealing surface, and if there is a slight scratch on the sealing surface, it may be damaged. Cause oil leakage in the engine, and when the sealant is applied unevenly, it is easy to block the bolt hole or the oil return hole due to extrusion, causing engine failure. When the sealant ne

The invention discloses an engine oil pan sealing device. An engine oil pan sealing gasket is annular, and is matched with a body of an engine in a contact way, wherein the first sealing surface of the engine oil pan sealing gasket is positioned at the top of the engine oil pan sealing gasket; the second sealing surface of the engine oil pan sealing gasket is positioned at the bottom of the engine oil pan sealing gasket; the third sealing surface of the engine oil pan sealing gasket is positioned on the lateral surface of the engine oil pan sealing gasket; an inner cavity is horizontally formed in a side away from the third sealing surface between the first and second sealing surfaces, and is matched with the flange surface of an oil pan; an oil pan frame is annular, has an L-shaped cross section, and is used for being matched with the body of the engine to clamp the oil pan sealing gasket. According to the engine oil pan sealing device, the sealing gasket is matched with the body of the engine in the contact way to realize linear sealing, so that the sealing gasket can be more closely contacted with the body of the engine; in addition, the inner cavity is formed in the sealing gasket to wrap the flange surface of the oil pan, so that a stressed area is enlarged, stress is more uniform, vibration and noise reduction functions are realized, the service life of the sealing gasket is prolonged, and a more reliable sealing effect is achieved.
Description
technical field [0001] The invention relates to the technical field of engine mechanical accessories, in particular to an engine oil pan sealing device. Background technique [0002] The oil pan is located at the lower part of the engine and is used to collect and store lubricating oil in the engine lubrication system, prevent the lubricating oil from oxidation, dissipate part of the heat, prevent impurities from entering and protect the crankcase. Therefore, there is a gap between the engine oil pan and the engine body. Large spaces need to be sealed. [0003] In the prior art, the oil pan is usually sealed by applying sealant on the contact surface between the oil pan and the engine body. However, this sealing method has high requirements on the sealing surface, and if there is a slight scratch on the sealing surface, it may be damaged. Cause oil leakage in the engine, and when the sealant is applied unevenly, it is easy to block the bolt hole or the oil return hole due t...
