The oil pan can absorb vibration transmitted to the oil pan from a machine body, so that noise caused by vibration of the oil pan is reduced, reduction of sealing surface pressure between the oil pan and the machine body caused by aging of the rubber sealing gasket can be relieved, and oil leakage faults between the oil pan and the machine body are prevented.

Description

Technical Field

[0001] The utility model relates to the field of engines, in particular to an oil pan sealing device with noise reduction and surface pressure compensation functions. Background Art

[0002] During engine operation, fuel periodically explodes, generating power that drives the main shaft. This periodic explosion causes periodic vibrations within the engine. Furthermore, the high-speed rotation of engine components requires lubrication, generating high-temperature oil mist.

[0003] The engine oil pan stores lubricating oil, essential for engine operation. The engine block, or the main structure, is the heart of the engine. While the engine block and oil pan are functionally separate systems and components, they are bolted together to form a complete engine unit. Utility Model Content

[0004] The purpose of the utility model is to provide an oil pan sealing device with noise reduction and surface pressure compensation functions, so as to reduce the noise caused by the vibration of the oil pan and alleviate the reduction of the sealing surface pressure between the oil pan and the engine body.

[0005] In order to achieve the above-mentioned purpose, the technical solution of the present utility model provides an oil pan sealing device with noise reduction and surface pressure compensation functions, including an engine body and an oil pan, a rubber sealing gasket is provided between the engine body and the oil pan, and a fixing bolt vertically penetrates the rubber sealing gasket to connect the engine body and the oil pan.

[0006] Preferably, the head of the fixing bolt is located below the connection.

[0007] Preferably, a preload spring is provided between the head of the fixing bolt and the connection point of the oil pan.

[0008] Preferably, the preload spring is sleeved on the rod of the fixing bolt.

[0009] In summary, the present invention has the following beneficial technical effects:

[0010] 1. The rubber seal can absorb the vibration transmitted from the engine body to the oil pan, thereby reducing the noise caused by the vibration of the oil pan;

[0011] 2. The preload force of the preload spring can alleviate the decrease in sealing surface pressure between the oil pan and the engine body caused by the aging of the rubber gasket, thereby preventing oil leakage between the oil pan and the engine body. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1 As shown, an embodiment of the utility model discloses an oil pan sealing device with noise reduction and surface pressure compensation functions, which includes an engine body 1 and an oil pan 2, a rubber sealing gasket 5 is provided between the engine body 1 and the oil pan 2, a fixing bolt 3 vertically penetrates the rubber sealing gasket 5 to connect the engine body 1 and the oil pan 2, the head of the fixing bolt 3 is located below the connection, a pre-tightening spring 4 is provided between the head of the fixing bolt 3 and the connection between the oil pan 2, and the pre-tightening spring 4 is sleeved on the rod of the fixing bolt 3.

[0017] A rubber gasket 5 is added between the engine body 1 and the oil pan 2. A preload spring 4 is added to the oil pan 2's fixing bolts 3 to secure the oil pan 2. The rubber gasket 5 absorbs vibrations transmitted from the engine body 1 to the oil pan 2, thereby reducing noise caused by the vibrations of the oil pan 2. Furthermore, the preload of the preload spring 4 mitigates the decrease in sealing surface pressure between the oil pan 2 and the engine body 1 caused by aging of the rubber gasket 5, thereby preventing oil leakage between the oil pan 2 and the engine body 1. Oil leakage can result in oil stains on the engine exterior, affecting its appearance and increasing engine oil consumption.

[0018] If the engine body 1 and the oil pan 2 are directly connected ( Figure 2 As shown, without the shock-absorbing rubber sealing pad 5), the vibration of the body 1 will be directly transmitted to the oil pan 2, generating a huge noise at the belly of the oil pan 2, affecting the user's hearing health and driving experience.

[0019] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
