[0002] Cylinder head gaskets are key sealing components in automobile engines, located between the cylinder head and the cylinder block. Their main function is to seal the combustion chamber, coolant passage, and oil passage, preventing leakage of high-temperature, high-pressure combustion gases, coolant, and oil. Split cylinder head gaskets are one type of cylinder head gasket.

[0003] Chinese Patent No. 200520124639.7 discloses a split cylinder head cover, including a cylinder head cover body. The cylinder head cover body includes an upper cylinder head cover and a lower cylinder head cover that can be fixedly connected. A high-temperature resistant sealing gasket is provided between the upper cylinder head cover and the lower cylinder head cover.

[0004] This invention has poor weather resistance and is prone to cracking or breaking after prolonged use, which affects the service life of the gasket.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a split cylinder head gasket.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A split cylinder head gasket includes a gasket body composed of multiple gasket units. Each gasket unit has a through hole in its center and mounting holes around its outer perimeter. Connecting pieces are mounted on both sides of each gasket unit, and the connecting pieces between adjacent gasket units are connected by a fixing mechanism. A reinforcing mesh is provided in the center of the interior of each gasket unit, and rubber pads are attached to both sides of the reinforcing mesh. Anti-crack mesh is embedded inside the rubber pads.

[0009] Optionally, a wear-resistant layer is provided on the outer side of the rubber pad, which is attached to the outer side of the rubber pad.

[0010] Optionally, the wear-resistant layer may be configured as either a fluorocarbon-based coating or a graphene-modified coating.

[0011] Optionally, the reinforcing mesh is configured as a copper mesh.

[0012] Optionally, the reinforcing mesh is configured with hexagonal openings.

[0013] Optionally, the anti-crack mesh is configured as a carbon fiber mesh.

[0014] Optionally, the fixing mechanism consists of a plug and a socket. The plug is located on the upper side of the connecting piece at one end of the gasket unit, and the socket is located on the upper side of the connecting piece on the other side of the gasket unit. The plug is inserted into the socket.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] 1. Modular design allows for flexible adjustment of the number of individual gaskets, dispersing stress concentration and reducing the risk of localized overload. Internal copper hexagonal reinforcing mesh provides high-strength support, while rubber pads on both sides absorb vibration, and carbon fiber anti-crack mesh inhibits crack propagation, significantly improving fatigue resistance and service life.

[0017] The wear-resistant layer is designed to increase the wear resistance of the outer side of the rubber pad, reduce wear caused by vibration during use, and extend the service life of the pad body.

[0018] The reinforcing mesh is made of copper sheets, utilizing the high rigidity of the metal to form a supporting framework. Copper's electrical and thermal conductivity aids in heat dissipation, preventing material aging caused by localized temperature rises. Furthermore, copper's corrosion resistance is superior to ordinary steel, making it suitable for use in humid or corrosive environments and ensuring long-term structural stability.

[0019] The fixing mechanism consists of a plug and a socket. Adjacent gasket units can be quickly and tool-free spliced ​​together via the plug and socket on the connecting plate. The interference fit provides a reliable mechanical connection, ensuring coordinated movement under dynamic loads and avoiding the risk of bolt loosening. In case of partial damage, individual gasket units can be replaced, reducing maintenance costs and improving maintenance convenience.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment provides a split cylinder head gasket, including a gasket body 1: the gasket body 1 is composed of multiple gasket units 2, a through hole 4 is provided in the center of the gasket unit 2, mounting holes 3 are provided around the outer perimeter of the gasket unit 2, connecting pieces 5 are installed on both sides of the gasket unit 2, the connecting pieces 5 between adjacent gasket units 2 are connected by a fixing mechanism 6, a reinforcing mesh 9 is provided in the center of the gasket unit 2, rubber pads 11 are attached to both sides of the reinforcing mesh 9, and anti-crack mesh 10 is embedded inside the rubber pads 11.

[0031] One application of this embodiment is as follows: the gasket body 1 is composed of multiple modular gasket units 2. Each unit has a through hole 4 at its center to ensure media flow, and mounting holes 3 around its perimeter provide mechanical fixing points. Connecting pieces 5 on both sides are quickly assembled using a tenon-and-mortise structure between plugs 7 and sockets 8, forming an expandable whole. The modular design allows for flexible increases or decreases in the number of gasket units 2, dispersing stress concentration and reducing the risk of localized overload. An internal copper hexagonal reinforcing mesh 9 provides high-strength support, rubber pads 11 on both sides absorb vibration, and a carbon fiber anti-crack mesh 10 inhibits crack propagation, significantly improving fatigue resistance and service life.

[0032] In this embodiment, a wear-resistant layer 12 is provided on the outer side of the rubber pad 11 and is attached to the outer side of the rubber pad 11. The wear-resistant layer 12 is provided to increase the wear resistance of the outer side of the rubber pad 11, reduce the wear caused by the shaking of the rubber pad 11 due to vibration during use, and extend the service life of the pad body 1.

[0033] In this embodiment, the wear-resistant layer 12 is configured as either a fluorocarbon-based coating or a graphene-modified coating. The outer side of the rubber pad 11 is covered with either a fluorocarbon-based or graphene-modified coating to form a dense protective layer. The fluorocarbon coating reduces media adhesion and improves corrosion resistance due to its low surface energy characteristics; the graphene-modified coating enhances surface hardness and reduces the coefficient of friction through its two-dimensional nanostructure. Both coatings can resist chemical erosion and mechanical wear, extending the service life of the pad body 1 in harsh environments.

[0034] In this embodiment, the reinforcing mesh 9 is a copper sheet mesh, which utilizes the high rigidity of the metal to form a supporting framework. The electrical and thermal conductivity of copper helps dissipate heat, preventing material aging caused by localized temperature rise. Simultaneously, copper has better corrosion resistance than ordinary steel, making it suitable for use in humid or corrosive media, ensuring long-term structural stability.

[0035] In this embodiment, the reinforcing mesh 9 has hexagonal mesh openings. This hexagonal mesh design provides maximum structural strength and stiffness with the same amount of material. The symmetrical distribution of stress in the hexagonal shape effectively resists deformation, allows for uniform distribution of the medium, and avoids localized pressure concentration.

[0036] In this embodiment, the crack-resistant mesh 10 is a carbon fiber mesh. The high tensile strength and modulus of the carbon fiber mesh 10 can effectively inhibit the initiation and propagation of cracks inside the rubber pad 11. The composite material layer of carbon fiber and rubber pad 11 forms a synergistic effect. The elasticity of the rubber pad 11 provides cushioning, and the rigidity of the carbon fiber enhances the crack resistance, significantly improving the durability and reliability of the pad body 1.

[0037] In this embodiment, the fixing mechanism 6 consists of a plug 7 and a socket 8. The plug 7 is located on the upper side of the connecting piece 5 at one end of the gasket unit 2, and the socket 8 is located on the upper side of the connecting piece 5 on the other side of the gasket unit 2. The plug 7 is inserted into the socket 8. The fixing mechanism 6, consisting of the plug 7 and the socket 8, allows adjacent gasket units 2 to be quickly and tool-free connected via the plug 7 and socket 8 on the connecting piece 5. The interference fit provides a reliable mechanical connection, ensuring coordinated movement under dynamic loads and avoiding the risk of bolt loosening. In case of partial damage, the gasket unit 2 can be replaced individually, reducing maintenance costs and improving maintenance convenience.
