Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a self-adjusting clutch. Background Art

[0002] The clutch pressure plate works by disengaging or engaging the friction plate with the flywheel, connecting and disconnecting the engine and transmission. When the driver depresses the clutch pedal, the pressure plate no longer applies pressure to the friction plate, eliminating friction between the plate and the flywheel. This allows the engine speed and the transmission input shaft to decouple, placing the vehicle in neutral. When the driver releases the clutch pedal, the pressure plate reapplies pressure to the friction plate, generating friction between the plate and the flywheel, transferring engine power to the transmission input shaft and enabling normal vehicle operation.

[0003] As can be seen from the above description, the friction plate plays a vital role in the power transmission between the clutch flywheel and the pressure plate. However, the existing clutch friction plate still has the following problems during use:

[0004] 1. The clutch friction plate often loses thickness due to friction during use, which results in less contact between the friction plate and the flywheel surface when the clutch pedal is stepped on, leading to low friction and slippage.

[0005] 2. Existing clutch friction plates are mostly integral structures, which have poor wear resistance. During long-term use, they need to be replaced regularly, resulting in a great waste of raw materials and bringing great inconvenience to people's car use. They cannot meet the actual needs of modern people. Summary of the Invention

It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0035] A self-adjusting clutch provided in an embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0036] Example 1:

[0037] like Figures 1 to 5 As shown, an embodiment of the present application provides a self-adjusting clutch, comprising a clutch housing 1, a diaphragm spring 2, a pressure plate 3, a compensation plate 4, and a friction plate 5, wherein the compensation plate 4 can push the diaphragm spring 2, the pressure plate 3 and the friction plate 5 downward by rotating the adjustment component 6, thereby playing a compensation role; wherein the friction plate 5 can be disassembled into a pressure block 51 and three friction blocks 52 by a disassembly and assembly component 7.

[0038] Furthermore, the rotation adjustment assembly 6 includes a bevel block 41 and a bevel groove 11, and a plurality of bevel blocks 41 are distributed circumferentially at equal intervals on the end of the compensation plate 4 facing the clutch housing 1, and a plurality of corresponding bevel grooves 11 are provided on the end of the clutch housing 1 facing the compensation plate 4, and the bevel blocks 41 abut against the bevel grooves 11; wherein, the compensation plate 4 can rotate around its axis through the action member 42.

[0039] Furthermore, the action member 42 includes a pushing block 43, and a plurality of pushing blocks 43 are equidistantly distributed circumferentially at one end of the compensation plate 4 facing the clutch housing 1. A movable groove 12 is provided on the clutch housing 1, and the pushing block 43 is installed in the movable groove 12; wherein, a spring 44 is movably sleeved on the outer surface of the pushing block 43, and the spring 44 is in a compressed state, a No. 1 clamping portion 13 is provided on the movable groove 12, and a No. 2 clamping portion 45 is provided on the pushing block 43, and the two ends of the spring 44 are respectively clamped on the No. 1 clamping portion 13 and the No. 2 clamping portion 45.

[0040] Furthermore, a tooth block 46 is provided on the end surface of the inclined block 41 abutting against the inclined groove 11 , and a tooth groove 14 is provided on the end surface of the inclined groove 11 abutting against the inclined block 41 .

[0041] Furthermore, a plurality of limit blocks 47 are equidistantly distributed circumferentially on one end of the compensation plate 4 facing the clutch housing 1 . A limit slot 15 is provided on the clutch housing 1 , and the limit blocks 47 are installed in the limit slot 15 .

[0042] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the friction plate 5 is not worn, the two ends of the friction plate 5 are respectively in contact with the external flywheel and the pressure plate 3, and the friction plate 5 rotates with the external flywheel, thereby realizing power transmission. When the friction plate 5 is worn to a certain extent, a gap is generated between the friction plate 5 and the external flywheel. Under the elastic force of the spring 44, the compensation plate 4 is pushed to rotate clockwise around its axis, thereby pushing the diaphragm spring 2 and the pressure plate 3 as a whole to slide toward the direction of the external flywheel, thereby playing a compensation role.

[0043] The cooperation between the tooth block 46 and the tooth groove 14 can ensure the tightness and stability of the contact between the compensation plate 4 and the clutch housing 1, so that the clutch maintains a relatively fixed position relationship inside during operation, ensuring the normal operation of the clutch;

[0044] During the rotation of the clutch housing 1 , the limiting block 47 and the pushing block 43 drive the compensation plate 4 to rotate together, thereby extending the service life of the spring 44 and preventing the inclined block 41 from being separated from the inclined slot 11 .

[0045] Example 2:

[0046] like Figures 6 to 8 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the disassembly and assembly component 7 includes a plug-in hole 511 and an adjustment hole 512, and the end of the pressure block 51 facing away from the diaphragm spring 2 is provided with a plug-in hole 511 and an adjustment hole 512, the plug-in hole 511 is communicated with the adjustment hole 512, and a protrusion 513 with an elliptical groove 515 is provided in the plug-in hole 511, and a plug-in block 521 is provided on the friction block 52, and the plug-in block 521 can be inserted into the plug-in hole 511 and the adjustment hole 512, and a groove 522 is provided on the plug-in block 521, and the protrusion 513 is plugged into the groove 522; wherein, the plug-in block 521 is locked in the plug-in hole 511 by a limit member 53.

[0047] Furthermore, the limiting member 53 includes an elliptical block 531 and a rotating block 532, and the elliptical block 531 and the rotating block 532 are fixedly connected via a connecting cylinder 533. The outer side surface of the pressing block 51 is provided with a circular groove 514 connected to the elliptical groove 515. The cylinder 511 is slidably installed in the circular groove 514, and the elliptical block 531 is slidably installed in the elliptical groove 515, and the thickness of the elliptical block 531 is the same as the thickness of the adjusting hole 512; wherein, the elliptical block 531 slides completely into the adjusting hole 512, and rotating 90 degrees can lock the plug-in block 521 in the plug-in hole 511.

[0048] Furthermore, the circular groove 514 is provided with a mounting groove 54 at the end facing away from the plug-in block 521, and the mounting groove 54 is installed with a mounting block 56 through a buckle 55. The mounting block 56 is provided with a stop groove 57 at the end facing the rotating block 532, and the rotating block 532 is inserted into the stop groove 57.

[0049] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the staff takes out the friction plate 5, then takes out the mounting block 56 from the mounting groove 54, and rotates the rotating block 532 90 degrees. The rotating block 532 drives the connecting cylinder 533 and the elliptical block 531 to rotate together, so that the elliptical block 531 is completely aligned with the elliptical groove 515, and then pulls the rotating block 532 outward. The rotating block 532 drives the connecting cylinder 533 and the elliptical block 531 to slide outward until the elliptical block 531 completely enters the elliptical groove 515. At this time, the plug-in block 521 can slide from the plug-in hole 511 into the adjustment hole 512, so that the protrusion 513 is separated from the groove 522, so that the friction block 52 can be taken out, and then the plug-in block 521 on the new friction block 52 is inserted into the adjustment hole 512 and moved outward. Push the friction block 52 so that the plug-in block 521 slides into the plug-in hole 511, and the protrusion 513 is inserted into the groove 522. Then push the rotating block 532 inward. The rotating block 532 drives the connecting cylinder 533 and the elliptical block 531 to slide inward until the elliptical block 531 completely enters the adjustment hole 512. Then rotate the rotating block 532 90 degrees. The rotating block 532 drives the connecting cylinder 533 and the elliptical block 531 to rotate together. At this time, the plug-in block 521 cannot slide into the adjustment hole 512. Then, the anti-rotation groove 57 is aligned with the rotating block 532, and the mounting block 56 is re-installed in the mounting groove 54 through the buckle 55. At this time, the replacement of one of the friction blocks 52 is completed. The remaining friction blocks 52 can be replaced through the same operation without having to replace them as a whole, saving raw materials and economic losses.
