Description

Technical Field

[0001] The utility model relates to the field of automotive flywheels, and particularly to a flywheel and a matching structure of a sealing disc gasket and a sealing ring. Background Technique

[0002] A flywheel is a disc-shaped part with a large moment of inertia, and its function is like an energy storage device. For a four-stroke engine, the pistons do work once every four piston strokes, that is, only the power stroke does work, while the exhaust, intake, and compression strokes all consume work. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft;

[0003] Chinese Patent with the publication number CN217539473U discloses a dual-mass flywheel and a matching structure of a sealing disc gasket and a sealing ring, which relates to the field of automotive flywheels, and includes a primary flywheel assembly and a secondary flywheel assembly. The primary flywheel assembly includes a front housing, a ring gear, a rear housing, a gasket, and a limit ring. The secondary flywheel assembly includes a force transmission plate, a sealing ring, a sealing disc gasket, and a spline hub. The force transmission plate, the sealing disc gasket, the sealing ring, and the spline hub are stacked in sequence from left to right. The force transmission plate is rotatably connected to the limit ring. There are two grooves on the sealing ring, and two protrusions are provided on the sealing disc gasket. The protrusions are clamped in the grooves. In this flywheel, protrusions are provided on the sealing disc gasket and corresponding grooves are provided on the sealing ring to form a circumferential thrust structure, which increases the rotational limit between the two and realizes synchronous operation, reduces the change of the stiffness performance of the sealing disc gasket due to wear, and further stabilizes the basic damping torque during the operation of the dual-mass flywheel.

[0004] The sealing disc gasket and the sealing ring of the above patent are in contact with each other. Although the rotational limit is increased to achieve synchronous operation, there is still friction between the inner wall of the sealing ring when the sealing disc gasket rotates to the position of the rotational limit. Therefore, lubricating oil needs to be injected. However, because the contact between the traditional sealing disc gasket and the sealing ring is too tight, it may be difficult for the lubricating oil to enter the gap between the two. Content of the Utility Model

[0005] The purpose of the present utility model is to provide a flywheel and a matching structure of a sealing disc gasket and a sealing ring. By arranging an installation groove in the sealing ring, a sealing disc gasket is arranged in the installation groove, a limiting groove is opened on the installation groove, a limiting block is arranged at a position corresponding to the limiting groove on the sealing disc gasket, and rubber soft pads are arranged at both ends of the limiting block. When the user injects lubricating oil into the sealing ring, when the sealing ring starts to rotate, the sealing disc gasket will start to rotate along with the rotation of the sealing ring. When the limiting block moves to one inner wall of the limiting groove, in this process, the sealing disc gasket will smear the lubricating oil originally in a solidified grease state onto the inner wall of the sealing ring through its own rotation. And due to the arrangement of the limiting groove and the limiting block, after the limiting block abuts against one side of the limiting groove, the sealing disc gasket cannot rotate independently and can only rotate synchronously with the sealing ring, thus solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A flywheel and a matching structure of a sealing disc gasket and a sealing ring, including a sealing ring, an installation groove is opened in the sealing ring, a limiting groove is opened around the installation groove, and further includes a sealing disc gasket. The sealing disc gasket is arranged in the installation groove, a limiting block is arranged on the sealing disc gasket, rubber soft pads are arranged at both ends of the limiting block, a felt layer is arranged at the lower end of the sealing disc gasket, a pipe sleeve is arranged on the inner wall of the sealing ring, a threaded column is arranged in the pipe sleeve, a cover plate is arranged on the outer surface of the threaded column, and a first bolt hole is opened on the cover plate.

[0007] Preferably, a fixing block is arranged on the cover plate, and the fixing block is welded to the cover plate.

[0008] Preferably, a connecting column is arranged at one end of the fixing block away from the cover plate.

[0009] Preferably, a flywheel is arranged on the outer surface of the connecting column, and the flywheel is bolted to the connecting column.

[0010] Preferably, an installation block is arranged at the top of the flywheel, and the installation block is bolted to the flywheel.

[0011] Preferably, heat dissipation holes are opened on the flywheel, and the heat dissipation holes are integrally formed with the flywheel.

[0012] Preferably, a second bolt hole is opened at the lower end of the sealing ring.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The utility model comprises an installation groove arranged inside a sealing ring, a sealing butterfly gasket arranged inside the installation groove, a limiting groove opened on the installation groove, a limiting block arranged at a position corresponding to the limiting groove on the sealing butterfly gasket, and rubber soft pads arranged at both ends of the limiting block. When a user injects lubricating oil into the sealing ring and the sealing ring starts to rotate, the sealing butterfly gasket will start to rotate along with the rotation of the sealing ring. When the limiting block moves to one inner wall of the limiting groove, during this process, the sealing butterfly gasket will smear the lubricating oil originally in a solidified grease state onto the inside of the sealing ring through its own rotation. And due to the arrangement of the limiting groove and the limiting block, after the limiting block abuts against one side of the limiting groove, the sealing butterfly gasket cannot rotate independently and can only rotate synchronously with the sealing ring, effectively avoiding the problem that in the prior art, the sealing butterfly gasket and the sealing ring are in contact with each other. Although the rotation limit is increased to achieve synchronous operation, there is still friction between the sealing butterfly gasket and the inner wall of the sealing ring when the sealing butterfly gasket rotates to the rotation limit position. Therefore, lubricating oil needs to be injected, but because the contact between the traditional sealing butterfly gasket and the sealing ring is too tight, it may be very difficult for the lubricating oil to enter the gap between the two contacts.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] In order to solve the problem in the prior art that since the sealing butterfly gasket and the sealing ring are abutted against each other, although the rotational limit is increased to achieve synchronous operation, there is still friction between the sealing butterfly gasket and the inner wall of the sealing ring when the sealing butterfly gasket rotates to the position of the rotational limit, so lubricating oil needs to be injected. However, because the contact between the traditional sealing butterfly gasket and the sealing ring is too tight, it may be difficult for the lubricating oil to enter the gap between the two. The following technical solutions are provided in this embodiment:

[0022] A flywheel and a matching structure of a sealing disc gasket and a sealing ring, including a sealing ring 9, an installation groove 11 is opened in the sealing ring 9, a limiting groove 12 is opened around the installation groove 11, and further includes a sealing butterfly gasket 13, the sealing butterfly gasket 13 is arranged in the installation groove 11, a limiting block 14 is arranged on the sealing butterfly gasket 13, rubber soft pads 17 are arranged at both ends of the limiting block 14, a felt layer 16 is arranged at the lower end of the sealing butterfly gasket 13, a pipe sleeve 10 is arranged on the inner wall of the sealing ring 9, a threaded column 8 is arranged in the pipe sleeve 10, a cover plate 1 is arranged on the outer surface of the threaded column 8, a first bolt hole 7 is opened on the cover plate 1, a fixing block 2 is arranged on the cover plate 1, the fixing block 2 is welded to the cover plate 1, a connecting column 3 is arranged at the end of the fixing block 2 away from the cover plate 1, a flywheel 4 is arranged on the outer surface of the connecting column 3, the flywheel 4 is bolted to the connecting column 3, an installation block 6 is arranged at the top of the flywheel 4, the installation block 6 is bolted to the flywheel 4, heat dissipation holes 5 are opened on the flywheel 4, the heat dissipation holes 5 are integrally arranged with the flywheel 4, and a second bolt hole 15 is opened at the lower end of the sealing ring 9;

[0023] In this embodiment, please refer to Figures 1 - 4 , an installation groove 11 is arranged in the sealing ring 9, a sealing butterfly gasket 13 is arranged in the installation groove 11, a limiting groove 12 is opened on the installation groove 11, a limiting block 14 is arranged at a position corresponding to the limiting groove 12 on the sealing butterfly gasket 13, and rubber soft pads 17 are arranged at both ends of the limiting block 14. When the user injects lubricating oil into the sealing ring 9 and the sealing ring 9 starts to rotate, the sealing butterfly gasket 13 will start to rotate along with the rotation of the sealing ring 9. When the limiting block 14 moves to one side inner wall of the limiting groove 12, in this process, the sealing butterfly gasket 13 will smear the originally solidified grease-like lubricating oil into the sealing ring 9 through its own rotation. And because of the arrangement of the limiting groove 12 and the limiting block 14, after the limiting block 14 abuts against one side of the limiting groove 12, the sealing butterfly gasket 13 cannot rotate independently and can only rotate synchronously with the sealing ring 9;

[0024] Working principle: An installation groove 11 is provided inside the sealing ring 9, a sealing butterfly gasket 13 is provided inside the installation groove 11, a limiting groove 12 is opened on the installation groove 11, a limiting block 14 is provided at a position corresponding to the limiting groove 12 on the sealing butterfly gasket 13, and rubber soft pads 17 are provided at both ends of the limiting block 14. When the user injects lubricating oil into the sealing ring 9, when the sealing ring 9 starts to rotate, the sealing butterfly gasket 13 will start to rotate along with the rotation of the sealing ring 9. When the limiting block 14 moves to one inner wall of the limiting groove 12, in this process, the sealing butterfly gasket 13 will smear the lubricating oil originally in a solidified grease state onto the inside of the sealing ring 9 through its own rotation. And due to the settings of the limiting groove 12 and the limiting block 14, after the limiting block 14 abuts against one side of the limiting groove 12, the sealing butterfly gasket 13 cannot rotate independently and can only rotate synchronously with the sealing ring 9.
