[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present utility model belong to the protection scope of the present utility model.

[0023] The following references Figures 1-3 The present utility model will be described as follows:

[0024] Embodiment: A clutch booster, comprising a cylinder 9 and a housing 10. A first connecting ring 11 is provided at the open end of the cylinder 9, and a second connecting ring 12 is provided on the housing 10. The first connecting ring 11 and the second connecting ring 12 are fixedly connected by bolts. The setting of the connecting rings increases the contact area of the connection. Compared with directly connecting the cylinder and the housing, the stress borne by the connection part can be more evenly distributed, thereby improving the stability and reliability of the connection. Using bolts for fixed connection has the advantages of convenient installation and disassembly, which is convenient for later maintenance and repair.

[0025] It further includes the above-mentioned strengthening fixing ring, which comprises a circular fixing ring body 1. The fixing ring body 1 is sleeved on the cylinder 9. The fixing ring body 1, the first connecting ring 11 and the second connecting ring 12 are fixedly connected by bolts, and the first connecting ring 11 is located between the fixing ring body 1 and the second connecting ring 12. After introducing the strengthening fixing ring, the stability and reliability of the entire connection structure have been significantly improved. The overall thickness and strength of the connection part are increased. The addition of the fixing ring body 1 makes the structure of the connection area more solid, which can better withstand the forces and vibrations from all directions, and reduces the problem of insufficient connection strength caused by the relatively thin wall thickness of the cylinder. Further disperse the stress borne by the connection part. Through the coordinated connection of the three components, the stress can be more evenly distributed over a larger area, reducing the risk of local stress concentration, thereby extending the service life of the connection structure.

[0026] The inner diameter of the fixing ring body 1 is equal to or slightly larger than the outer diameter of the cylinder 9. This size design can ensure that the fixing ring body 1 is tightly and smoothly sleeved on the cylinder 9, providing stable support and fixing functions. The fixing ring body 1 is provided with connection holes 2, and convex ears 5 are provided on the outer side wall of the fixing ring body 1. The connection holes 2 are arranged on the convex ears 5, and bolts pass through the connection holes 2 to connect with the holes on the first connecting ring 11 and the second connecting ring 12. The bolts pass through the connection holes 2 to connect with the holes on the first connecting ring 11 and the second connecting ring 12, forming a firm overall connection structure. This connection method can effectively fix the cylinder 9, the fixing ring body 1 and the housing 10 tightly together to jointly withstand various forces and vibrations during the working process.

[0027] The outer lateral surface in the radial direction of the fixing ring body 1 is provided with a holding portion, and the holding portion extends along the axial direction of the fixing ring body 1. The holding portion includes a first holding portion 3 and a second holding portion 4, and the first holding portion 3 and the second holding portion 4 are respectively located on both sides in the axial direction of the fixing ring body 1. The inner diameter of the first holding portion 3 is equal to the inner diameter of the fixing ring body 1. The inner diameter of the second holding portion 4 is equal to the outer diameter of the fixing ring body 1. The first holding portion 3 clamps on the air cylinder 9, and the second holding portion 4 clamps on the second connecting ring 12. A plurality of second holding portions 4 are circumferentially spaced on the fixing ring body 1, and the number and position of the first holding portion 3 correspond to the number and position of the second holding portion 4. The holding portion significantly enhances the connection stability and integrity between the fixing ring and the air cylinder and the second connecting ring. The first holding portion 3 clamps on the air cylinder 9, and its inner diameter is equal to the inner diameter of the fixing ring body 1, which can closely fit the air cylinder 9, providing a reliable clamping effect and preventing the fixing ring from axially or radially displacing on the air cylinder. The second holding portion 4 clamps on the second connecting ring 12, and its inner diameter is equal to the outer diameter of the fixing ring body 1. This design increases the contact area with the second connecting ring 12, further disperses the stress at the connection, and improves the connection strength and stability. A plurality of second holding portions 4 are circumferentially spaced on the fixing ring body 1, and the number and position of the first holding portion 3 correspond to those of the second holding portion 4, making the force on the fixing ring more uniform in all directions and effectively avoiding deformation or damage caused by excessive local force.

[0028] Two first fixing holes 6 are provided on the second holding portion 4, and the first fixing holes 6 penetrate through the fixing ring body 1 and the second holding portion 4. It further includes a U-shaped wire clamp 7, and two second fixing holes 8 are respectively provided at both ends of the wire clamp 7. The first fixing holes 6 and the second fixing holes 8 are correspondingly arranged, and a screw is connected in the first fixing holes 6 and the second fixing holes 8. The wire clamp 7 can be disassembled and assembled through the screw, which is convenient for positioning and fixing the pipeline. By providing two first fixing holes 6 on the second holding portion 4 and matching them with the second fixing holes 8 on the wire clamp 7, and realizing the disassembly and assembly of the wire clamp 7 through the screw, this design firstly increases the convenience of pipeline fixing. The wire clamp 7 can effectively fix the relevant pipeline in place, avoiding the pipeline from shaking, wearing or interfering with other components during the vehicle operation, and improving the reliability and stability of the whole system. Secondly, the convenient disassembly and assembly feature is convenient for maintenance and repair. When it is necessary to check, replace or adjust the pipeline, the wire clamp 7 can be quickly disassembled, and then easily reinstalled after completing the relevant operations. The corresponding arrangement of the first fixing holes 6 and the second fixing holes 8 and the connection method of the screw ensure the connection stability and can withstand the tension and vibration that the pipeline may generate.

[0029] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
