Description

Technical Field

[0001] The utility model relates to an automobile engine sealing component, more specifically, it relates to an automobile engine assembly sealing component. Background Art

[0002] There are oil channels and water channels inside the engine cylinder block, which cannot be formed as one piece during casting. Various oil and water channels need to be processed later. Due to processing technology issues, holes of different sizes will be left on the cylinder block, which need to be blocked later, especially the sealing water plugs of the water channels. Due to long-term contact with antifreeze, the mainstream ethylene glycol antifreeze on the market will form acidic substances under high temperature conditions. If the preservative content in the antifreeze does not meet the standard, it will gradually fail over time and cannot neutralize the acidic substances, resulting in antifreeze corrosion and water plugging.

[0003] Crankcase blowby is generally caused by aging of the cylinder gasket and corrosion of the cylinder block and cylinder head, which leads to a loose seal between the cylinder head and the cylinder block, causing compressed gas to leak through the gap into the cooling water channels and oil channels around the cylinder head and cylinder block.

[0004] Automobile engine assembly seals are a type of sealing component used in automobile engines. Their main function is to seal the holes and openings on the engine cylinder block to ensure stable engine operation. They are usually composed of a seal body and a sealing ring.

[0005] When a car engine is running, the maximum oil temperature can reach 135°C. To prevent oil mist and gas blowby, very high requirements are placed on the material properties of sealing components and the stability of the sealing structure. Currently, the market basically relies on imports. Utility Model Content

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A seal for an automobile engine assembly includes a seal body and a seal ring. The seal body has a mounting groove on its side end, the mounting groove surrounds the seal body, the seal ring can be embedded in the mounting groove, and the side end of the seal ring extends out of the mounting groove.

[0009] The seal body is made of EN AW-6082-T6 aluminum alloy.

[0010] The seal body has an interference fit with the cylinder block of the engine.

[0011] Furthermore, the top edge and the bottom edge of the main body of the seal are both chamfered, the cross-section of the installation groove is U-shaped, and the upper and lower edges of the groove opening of the installation groove are both chamfered.

[0012] Furthermore, the mounting groove is located at one third of the height direction of the sealing body.

[0013] Furthermore, the sealing body is in the shape of a disc, the sealing ring is in the shape of a ring, and the cross section of the sealing ring is circular.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] 1. The material stability is extremely high, and the high temperature stability meets 100%;

[0016] 2. High sealing performance. By utilizing the engine installation matching characteristics of the product, an additional interference fit between the component body and the engine is added under the original annular sealing conditions to achieve stable sealing and meet the high temperature and complex working conditions of the engine;

[0017] 3. The seal has a simple structure, is lightweight, reduces engine weight, and is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS
