For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0029] The present application will be further described in detail below by means of the drawings and examples.

[0030] Referring to Figures 1 to 10 The embodiments of the present application provide a reusable AMT self-adjusting clutch cover assembly, which comprises an outer cover 1 and a connecting ring 4, the front surface of the connecting ring 4 is provided with a main pressure disc 5, the front surface of the main pressure disc 5 is provided with an adjusting ring 6, the outer cover 1 is fixedly installed on the outer side of the main pressure disc 5 and the adjusting ring 6, and the main pressure disc 5 and the adjusting ring 6 are provided with an anti-back component 2 and a backtracking component 3, the backtracking component 3 comprises a supporting plate 33, the supporting plate 33 is fixedly installed on the front surface of the adjusting ring 6, the top of the supporting plate 33 is rotatably connected with a gear 31, the inside of the main pressure disc 5 is fixedly installed with a rack 32, the gear 31 and the rack 32 are mutually engaged, the top of the supporting plate 33 is rotatably connected with a clamping rod 35, and the clamping rod 35 is inserted into the inside of the gear 31.

[0031] The clamping rod 35 and the side wall of the supporting plate 33 are fixedly installed with a spring, the top of the supporting plate 33 is rotatably connected with a push block 34, and the push block 34 is located on both sides of the clamping rod 35. The top inside of the gear 31 is provided with a hexagonal groove. The anti-back component 2 comprises a one-way ratchet piece 23 and a pawl 25, the one-way ratchet piece 23 is fixedly installed on the side surface of the main pressure disc 5 through a second rivet 24, and the pawl 25 is fixedly installed on the side surface of the adjusting ring 6 through a first rivet 22. The pawl 25 is clamped in the inside of the teeth of the one-way ratchet piece 23. The inside of the adjusting ring 6 is screwed with a mounting screw 21, the end surface of the mounting screw 21 abuts against the outside of the pawl 25, and the pawl 25 is an elastic metal sheet.

[0032] In this embodiment, when the anti-backup function is implemented, the mounting screw 21 is rotated by a hexagonal wrench, the extrusion pawl 25 is rotated by the mounting screw 21, and the one-way rotation of the one-way ratchet piece 23 is realized by clamping the one-way ratchet piece 23 inside the pawl 25, thereby realizing the anti-backup function. When the backtracking function is realized, the outer cover 1 is first removed, the mounting screw 21 is first rotated to move the mounting screw 21 outward, the pawl 25 is separated from the one-way ratchet piece 23 under the action of the deformation force of the pawl 25, the anti-backup function is disabled, then the state of the clamping rods 35 on both sides is changed by rotating the push block 34, the clamping rod 35 on the other side is clamped with the gear 31, thereby changing the rotation direction of the one-way gear 31, and the gear 31 is rotated by the hexagonal groove, the gear 31 drives the rack 32 to move, and the adjusting ring 6 returns to the original position. After returning, the mounting screw 21 is screwed again, the pawl 25 is clamped inside the one-way ratchet piece 23 again, the anti-backup function is restored, and the self-adjusting backtracking of the cover assembly is completed.

[0033] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0034] Working principle: when the anti-backup function is needed, the mounting screw 21 is rotated by a hexagonal wrench, the mounting screw 21 is extruded as a flexible metal sheet during rotation, the pawl 25 is tightly clamped inside the teeth of the one-way ratchet piece 23, the clamping mode is relied on to limit the one-way rotation of the one-way ratchet piece 23, thereby effectively preventing the reverse movement of the related components, ensuring the normal working order of the clutch and the overall stability.

[0035] When the clutch cover assembly needs to be backtracked and adjusted, the outer cover 1 is first removed, then the mounting screw 21 is operated, the mounting screw 21 is moved outward by rotating the mounting screw 21, the pawl 25 is separated from the one-way ratchet piece 23 under the action of the deformation force of the pawl 25, and the anti-backup function is temporarily disabled.

[0036] Then, the state of the clamping rods 35 on both sides is changed by rotating the push block 34 located on the top of the support plate 33 and on both sides of the clamping rod 35, so that the clamping rod 35 on the other side is clamped with the gear 31, thereby changing the rotation direction of the gear 31 (a hexagonal groove is formed in the top inside of the gear 31 for subsequent operation).

[0037] Then, the gear 31 is rotated by a tool through the hexagonal groove, since the gear 31 is engaged with the rack 32 fixedly installed inside the main pressure plate 5, the rotating gear 31 drives the rack 32 to move, and further drives the adjusting ring 6 connected thereto to move, until the adjusting ring 6 returns to the original initial position.

[0038] After the adjustment ring 6 is reset, the installation screw 21 is screwed again, so that the pawl 25 is clamped to the inside of the one-way ratchet piece 23, the anti-reverse function is restored, and the whole clutch cover assembly self-adjusting reset process is completed, so that the clutch can maintain good working condition, improve its service life and reduce the use cost.
