Description

Technical Field

[0001] The utility model relates to the technical field of cylinder gaskets, in particular to a modified three-joint surface cylinder gasket. Background Art

[0002] At present, the designed structure of the cylinder gasket is three-layer, including the original first functional layer (6), the original second functional layer (7), and the original third functional layer (8). This structure is as shown in the attached drawings Figure 3 and the material is SUS301H. The form of the sealing ribs is the full-wave and semi-wave sealing rib type, and the riveting method of the gasket is rivet riveting.

[0003] However, the design of the three-joint surface position of the cylinder gasket in the prior art is a planar structure. When the cylinder gasket is installed on the engine, it is necessary to manually apply sealant between each layer. Currently, the caulking method requires manually separating each layer of the cylinder gasket, then inserting the sealant gun into the gasket to apply sealant (the caulking position is as shown in the attached drawings Figure 4 ). The process is cumbersome, inconvenient to operate, and the operation time is long. In order to improve this situation, a modified three-joint surface cylinder gasket is designed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a modified three-joint surface cylinder gasket to solve the above problems.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A modified three-joint surface cylinder gasket of the utility model includes:

[0007] The first functional layer, the second functional layer, and the third functional layer that constitute the three-joint surface cylinder gasket;

[0008] The first functional layer is a planar structure;

[0009] Caulking functional areas are arranged on the second functional layer and the third functional layer to apply sealant in the caulking functional areas, so that the sealant can be dispersed from the caulking functional areas between the first functional layer and the second functional layer, between the second functional layer and the third functional layer, and between the third functional layer and the surface of the cylinder gasket installation position.

[0010] Further, the materials of the first functional layer, the second functional layer, and the third functional layer are SUSH.

[0011] Further, the three-joint surface cylinder gasket composed of the first functional layer, the second functional layer, and the third functional layer has sealing ribs, and the form of the sealing ribs is the full-wave and semi-wave sealing rib type.

[0012] Further, the first functional layer, the second functional layer, and the third functional layer are riveted together by rivets.

[0013] Further, the caulking functional area includes a first caulking hole opened on the second functional layer and a second caulking hole opened on the third functional layer. The positions of the first caulking hole and the second caulking hole correspond to each other and are interconnected;

[0014] By injecting sealant into the first caulking hole and the second caulking hole, the sealant can be dispersed between the first functional layer and the second functional layer, between the second functional layer and the third functional layer, and between the third functional layer and the surface of the cylinder head gasket installation position.

[0015] In the above technical solution, a modified three-joint surface cylinder head gasket provided by the present utility model has the following beneficial effects:

[0016] The cylinder head gasket is designed such that the first functional layer has a planar structure, and the first caulking hole and the second caulking hole of the caulking functional area are added to the positions of the second functional layer and the third functional layer. After the cylinder head gasket is installed, only one injection is required into the caulking functional area during caulking, and then through the extrusion during the installation of the cylinder block and cylinder head, the sealant is dispersed to the positions of the other two layers by extrusion. With this design structure, without changing the product process, the operation steps of manual caulking after installation are reduced, which facilitates the operation of employees, reduces the operation man-hours, and saves costs.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0025] Please refer to Figure 1-2 , a modified triple-joint surface cylinder gasket, comprising:

[0026] The first functional layer 1, the second functional layer 2 and the third functional layer 3 that constitute the triple-joint surface cylinder gasket;

[0027] The first functional layer 1 is a planar structure;

[0028] Caulking functional areas are provided on the second functional layer 2 and the third functional layer 3 for caulking in the caulking functional areas, so that the sealant can be dispersed from the caulking functional areas between the first functional layer 1 and the second functional layer 2, between the second functional layer 2 and the third functional layer 3, and between the third functional layer 3 and the surface of the cylinder gasket installation position.

[0029] That is to say, on the premise that the original structures and processing technologies of the first functional layer 1, the second functional layer 2 and the third functional layer 3 remain unchanged, caulking functional areas are provided at the positions of the second functional layer 2 and the third functional layer 3, and then caulking is carried out once. Then, after the cylinder block and cylinder head are installed and extruded, the sealant is extruded and dispersed to the positions of the other two layers. Through this design structure, without changing the product process, the operation steps of manual caulking after installation are reduced, which facilitates the operation of employees, reduces the operation man-hours, and saves costs.

[0030] Furthermore, the materials of the first functional layer 1, the second functional layer 2 and the third functional layer 3 are SUS301H, which belong to the original cylinder gasket process materials.

[0031] Furthermore, the triple-joint surface cylinder gasket composed of the first functional layer 1, the second functional layer 2 and the third functional layer 3 has sealing ribs, and the form of the sealing ribs is a sealing rib type of full corrugation and half corrugation to form the overall structure of the cylinder gasket.

[0032] Furthermore, the first functional layer 1, the second functional layer 2 and the third functional layer 3 are riveted together through rivets to complete the overall fixation of the cylinder gasket.

[0033] Further, the sealant injection functional area includes a first sealant injection hole 4 formed in the second functional layer 2 and a second sealant injection hole 5 formed in the third functional layer 3. The first sealant injection hole 4 and the second sealant injection hole 5 are corresponding in position and communicate with each other. In this embodiment, small holes with a diameter of 3 mm are added at the three-joint surface positions of the second functional layer 2 and the third functional layer 3, namely the first sealant injection hole 4 and the second sealant injection hole 5.

[0034] By injecting sealant into the first sealant injection hole 4 and the second sealant injection hole 5, the sealant entering the first sealant injection hole 4 and the second sealant injection hole 5 can directly reach the positions between the first functional layer 1 and the second functional layer 2, between the second functional layer 2 and the third functional layer 3, and between the third functional layer 3 and the surface of the cylinder gasket installation position, so as to enable one-time sealant injection. Then, after the cylinder block and cylinder head are installed and extruded, the sealant is extruded and dispersed to the positions of the other two layers, and further the sealant is directly dispersed between the first functional layer 1 and the second functional layer 2, between the second functional layer 2 and the third functional layer 3, and between the third functional layer 3 and the surface of the cylinder gasket installation position to complete sealant injection.

[0035] In summary, the cylinder gasket is designed such that the first functional layer has a planar structure, and the first sealant injection hole and the second sealant injection hole with hole structures are added to the positions of the second functional layer and the third functional layer in the sealant injection functional area. After the cylinder gasket is installed, when injecting sealant, it only needs to be injected once into the sealant injection functional area, and then after the cylinder block and cylinder head are installed and extruded, the sealant is extruded and dispersed to the positions of the other two layers. With this design structure, without changing the product process, the operation steps of manual sealant injection after installation are reduced, which facilitates the operation of employees, reduces the operation man-hours, and saves costs.

[0036] Only some exemplary embodiments of the present invention are described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
