DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figures 1 to 5As shown in the figure, this embodiment includes an outer end cover 1, an annular disc base 2, a pressure plate 3, a spring hub 4, a friction plate 5, and a flywheel 6. The outer end cover 1 is formed with a circular connecting leg 11. There are three slots 12 opened on the connecting leg 11. Inside the outer end cover 1, several circumferentially arranged limiting pieces 13 are integrally formed. On the inner side of the outer end cover 1 at the intervals of the limiting pieces 13, a locking elbow 14 is formed through processing. On the annular disc base 2, several circumferentially arranged pressing strips 21 are formed. The outer end of the pressing strip 21 is a narrowed structure and is formed with a profile groove 22. The pressure plate 3 is a circular ring structure and several abutting columns 31 are formed on the pressure plate 3. During installation, the abutting columns 31 are in contact with the inner side of the outer end cover 1 to play a supporting role. On the pressure plate 3 inside the abutting columns 31, locking grooves 32 with the same number and position as the locking elbows 14 are opened. During installation, the locking elbows 14 pass through the profile grooves 22 and are fixedly connected to the locking grooves 32.

[0019] For further details, as Figures 1 to 3 shown, the locking elbow 14 is in the shape of a nearly rounded rectangular body at 90°. The end of the locking elbow 14 is connected to the locking groove 32 at a right angle. This connection structure enables the locking elbow 14 to be more firmly fixedly connected to the locking groove 32.

[0020] As Figures 1 to 5 shown, the rear side of the pressure plate 3 is fixedly connected to the friction plate 5. The spring hub 4 is fixedly installed inside the pressure plate 3 and is fixedly connected to the friction plate 5. The flywheel 6 is fixedly installed outside the friction plate 5. The outer end cover 1 covers the outside of the annular disc base 2, the pressure plate 3, the spring hub 4, and the friction plate 5 and is fixedly connected to the flywheel 6 through the connecting leg 11. There are three convex pieces 33 formed on the outer periphery of the pressure plate 3. One end of the convex piece 33 extends out of the slot 12. The convex piece 33 is used for connecting an external component to the pressure plate 3 through the convex piece 33.

[0021] For further details, as Figures 1 to 4 shown, the end of the pressing strip 21 on the annular disc base 2 is set in an arc-shaped structure. An anti-vibration ring 15 is formed on the inner side of the outer end cover 1. During installation, the anti-vibration ring 15 is in contact with the arc-shaped part at the end of the pressing strip 21. The anti-vibration ring 15 plays an anti-vibration and protective role for the annular disc base 2.

[0022] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0023] Although various terms are used more frequently in this text, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the present utility model; any interpretation of them as an additional limitation is contrary to the spirit of the present utility model.
