Description

Technical Field

[0001] The present application belongs to the technical field of clutch covers, and in particular relates to a motorcycle clutch cover. Background Art

[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. While the car is driving, the driver can step on or release the clutch pedal as needed to temporarily separate and gradually engage the engine and gearbox, so as to cut off or transfer the power input from the engine to the transmission. The clutch is a commonly used component in mechanical transmission, which can separate or engage the transmission system at any time. The basic requirements for it are: smooth engagement, quick and complete separation; easy adjustment and repair; small overall dimensions; small mass; good wear resistance and sufficient heat dissipation capacity; easy and labor-saving operation. Commonly used types are divided into two categories: tooth type and friction type.

[0003] Patent publication number CN215673274U discloses a loose-proof end cover for a motorcycle clutch, comprising an end cover body and a shell, a plurality of first ears being provided on the peripheral side of the shell, an outer edge being provided between the first ears and the shell, a shaft being rotatably connected to the outer edge, a reinforcing plate being fixed to one end of the shaft away from the outer edge, a plurality of second ears being provided on the peripheral side of the end cover body, the plurality of second ears being respectively positioned opposite to the plurality of first ears, and the structural features of the first ears being consistent with those of the second ears.

[0004] The above patent prevents the displacement and falling off of the first screw by setting a rotatable reinforcement plate and a limiting member for limiting, thereby improving the stability and tightness between the end cover body and the shell. However, its structure is relatively complex and occupies a large space on the outside, and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a motorcycle clutch cover that can solve the above problems.

[0006] The purpose of this application is to provide a motorcycle clutch cover, including a housing, including:

[0007] A clutch end cover is provided on the housing;

[0008] A first lug is provided on the edge of the shell;

[0009] The second lug is provided on the edge of the clutch end cover;

[0010] A lug locking structure is provided on the first lug and the second lug and is used to fix the first lug and the second lug;

[0011] There are multiple first ears and multiple second ears, and the overall diameter of the ear locking structure is smaller than that of the first ears and the second ears.

[0012] The aforementioned motorcycle clutch cover, comprising a clutch end cover, a first lug, a second lug, and a lug-to-lug locking structure, achieves a simpler structure than conventional designs requiring complex reinforcement plates and stoppers, reducing production costs and facilitating manufacturing and maintenance. Because the lug-to-lug locking structure has a smaller overall diameter than the first and second lugs, the outer side of the clutch cover does not occupy excessive space during installation and use, enhancing the overall layout and aesthetics of the motorcycle.

[0013] At the same time, although the structure is simplified, by setting multiple first support ears and second support ears, and corresponding support ear locking structures, the clutch end cover and the housing can be effectively fixed to avoid displacement and falling off problems, thereby ensuring the stability and reliability of the clutch cover during operation.

[0014] Furthermore, the lug locking structure includes:

[0015] A first mounting hole is provided on the second support ear;

[0016] A second mounting hole is provided on the first ear;

[0017] A threaded hole is provided on the first support ear and is connected to the second mounting hole;

[0018] A fastening bolt passes through the first mounting hole and the second mounting hole and then fits into the threaded hole;

[0019] Wherein, the diameter of the threaded hole is smaller than the diameter of the second mounting hole.

[0020] The lug-locking structure achieves precise locking through the coordination of the first and second mounting holes and the threaded holes. After passing the fastening bolts through the first and second mounting holes, they mate with the threaded holes, ensuring a secure connection between the clutch cover and the housing. The design of the lug-locking structure also makes the installation process simpler and more intuitive. Simply pass the fastening bolts through the first and second mounting holes and then screw them into the threaded holes, reducing installation effort and improving efficiency. Furthermore, due to its relatively simple and universal design, the lug-locking structure can accommodate clutch cover and housings of varying sizes and shapes, increasing its practicality and application range. When the clutch cover needs to be removed or repaired, simply unscrew the fastening bolts, eliminating the need for a complex disassembly process and reducing maintenance costs and time.

[0021] Further: the lug locking structure further includes:

[0022] Hidden slot, set on the second lug;

[0023] An isolation protrusion is disposed in the second hidden groove, and a third mounting hole communicating with the first mounting hole is provided on the isolation protrusion;

[0024] a cover cap, which is disposed on the isolation protrusion and connected to the isolation protrusion, and is provided with a limiting hole connected to the third mounting hole;

[0025] The diameter of the limiting hole is the same as the diameter of the rod of the fastening bolt.

[0026] The design of the hidden groove and isolation protrusion conceals some components of the lug-locking mechanism, not only improving the clutch cover's aesthetics but also helping to reduce the impact of external factors such as dust and moisture on the lug-locking mechanism. Furthermore, the design of the cap connected to the isolation protrusion and the provision of a stopper hole ensure that the fastening bolt will not accidentally fall off during the tightening process. The stopper hole has the same diameter as the fastening bolt shank, further enhancing the reliability and safety of the lug-locking mechanism.

[0027] Although the lug locking structure incorporates hidden slots, isolation protrusions, and a cap, the design of these components remains relatively simple for installation and maintenance. Installation requires simply inserting the fastening bolt through the stopper hole, the third mounting hole, the first mounting hole, and the second mounting hole, and then threading it into the threaded hole. Maintenance requires simply unscrewing the fastening bolt and removing the cap for necessary inspection and repair. Furthermore, the cap's connection to the isolation protrusion and the provision of a limit hole prevent the fastening bolt from loosening due to vibration or external forces during use, ensuring a tight connection and stability between the clutch cover and housing.

[0028] Furthermore, the diameters of the first mounting hole, the second mounting hole and the third mounting hole are the same, and gaps are provided between the three and the fastening bolts.

[0029] Because the diameters of the first, second, and third mounting holes are identical to the shank diameter of the fastening bolts, and a gap is provided between them, this helps reduce wear caused by threaded fit. The gaps also allow the bolts to move freely during installation and removal, thus preventing wear and damage caused by excessive friction. The presence of the gaps also simplifies the installation process, allowing the fastening bolts to pass more easily through the various mounting holes without becoming stuck or becoming difficult to rotate due to the tight threaded fit. This improves installation efficiency and reduces potential damage caused by installation difficulties. Reduced wear and improved installation efficiency both help extend the life of the clutch cover and reduce maintenance costs and replacement frequency by reducing damage and the need for replacement due to wear.

[0030] Furthermore, an abutting inner ring is provided in the gap, an abutting outer ring is provided on the fastening bolt, a spring is provided between the abutting inner ring and the abutting outer ring, and the spring is located in the gap and sleeved outside the fastening bolt.

[0031] The preload generated by the compressed spring significantly improves the locking effect between the clutch cover and the housing, helping to prevent the clutch cover from loosening due to vibration or external forces during use, thereby enhancing overall stability and reliability. Furthermore, the spring's elastic force not only provides additional locking force during installation but also assists during removal. When the fastening bolts need to be removed, the spring's elastic force helps the bolts to be pulled out of the mounting holes more easily, thereby improving removal efficiency. The presence of the spring also effectively mitigates friction and impact forces on the fastening bolts during installation and removal, helping to reduce wear between the bolts and the mounting holes and extending their service life.

[0032] Furthermore, both the abutting inner ring and the abutting outer ring are provided with limiting protrusions, and both ends of the spring are connected to the limiting protrusions.

[0033] By providing limiting protrusions on the inner and outer abutment rings and connecting both ends of the spring to these protrusions, the position of the spring within the mounting hole can be effectively limited. This ensures that the spring does not deviate from its predetermined path during expansion and contraction, thereby preventing accidental contact between the spring and the fastening bolts or other components. At the same time, limiting the spring position helps prevent the spring from being damaged during installation, use, or removal. If the spring is able to move freely or deviate from its predetermined path, it may rub or collide with surrounding components, causing damage. By fixing the spring's position, this risk can be significantly reduced.

[0034] Although the design of the limit protrusion has been added, this design does not increase the complexity of installation and maintenance. On the contrary, since the position of the spring is fixed, the installation and maintenance process becomes simpler and more intuitive. The design of limiting the position of the spring also helps to improve the safety of the clutch cover. If the spring can move freely during the expansion and contraction process, it may interfere with surrounding components, resulting in potential safety hazards. By fixing the position of the spring, this risk can be significantly reduced.

[0035] The beneficial effects of this application are:

[0036] 1. By designing a clutch cover including a clutch end cover, a first support ear, a second support ear, and a support ear locking structure, the structure of the present application is simpler than the traditional design that requires complex reinforcement plates and limiters, which not only reduces production costs but also facilitates manufacturing and maintenance;

[0037] 2. Since the overall diameter of the lug locking structure is smaller than that of the first and second lugs, the outer side of the clutch cover will not take up too much space during installation and use, which is beneficial to the overall layout and aesthetics of the motorcycle;

[0038] 3. Although the structure is simplified, the clutch cover and the housing can be effectively fixed by providing multiple first and second ears and corresponding ear locking structures, avoiding displacement and falling off problems, and ensuring the stability and reliability of the clutch cover during operation.

DETAILED DESCRIPTION

[0044] The following will be combined with the accompanying drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0045] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. 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.

[0046] The motorcycle clutch cover provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0047] Example 1:

[0048] like Figures 1 to 4 As shown, the embodiment of the present application provides a motorcycle clutch cover, including a housing 100, including:

[0049] The clutch end cover 200 is provided on the housing 100;

[0050] The first ear 110 is provided on the edge of the housing 100;

[0051] The second lug 210 is provided on the edge of the clutch end cover 200;

[0052] The ear locking structure 300 is provided on the first ear 110 and the second ear 210 and is used to fix the first ear 110 and the second ear 210;

[0053] There are multiple first lugs 110 and multiple second lugs 210 , and the overall diameter of the lug locking structure 300 is smaller than that of the first lug 110 and the second lug 210 .

[0054] In some implementations of the embodiments of this application, Figure 1 As shown, the clutch cover of a motorcycle, comprising a clutch end cover 200, a first lug 110, a second lug 210, and a lug locking structure 300, is designed. Compared to conventional designs requiring complex reinforcement plates and stoppers, the present invention offers a more concise structure, reducing production costs and facilitating manufacturing and maintenance. Because the overall diameter of the lug locking structure 300 is smaller than that of the first lug 110 and the second lug 210, the outer side of the clutch cover does not occupy excessive space during installation and use, improving the overall layout and aesthetics of the motorcycle.

[0055] At the same time, although the structure is simplified, by providing multiple first ears 110 and second ears 210, and corresponding ear locking structures 300, the clutch end cover 200 and the housing 100 can be effectively fixed to avoid displacement and falling off problems, thereby ensuring the stability and reliability of the clutch cover during operation.

[0056] Example 2:

[0057] An embodiment of the present application provides a motorcycle clutch cover. In addition to the above-mentioned technical features, the motorcycle clutch cover of the embodiment of the present application also includes the following technical features.

[0058] like Figure 4 As shown, the ear locking structure 300 includes:

[0059] A first mounting hole 310 is provided on the second ear 210;

[0060] The second mounting hole 320 is provided on the first ear 110;

[0061] A threaded hole 330 is provided on the first support ear 110 and communicates with the second mounting hole 320;

[0062] A fastening bolt 340 passes through the first mounting hole 310 and the second mounting hole 320 and then fits into the threaded hole 330;

[0063] The diameter of the threaded hole 330 is smaller than the diameter of the second mounting hole 320 .

[0064] In the embodiment of the present application, the lug locking structure 300 achieves a precise locking function through the coordination of the first mounting hole 310, the second mounting hole 320, and the threaded hole 330. After the fastening bolt 340 passes through the first and second mounting holes 310, 320, it mates with the threaded hole 330, ensuring a secure connection between the clutch cover 200 and the housing 100. Furthermore, the design of the lug locking structure 300 makes the installation process simpler and more intuitive. Simply insert the fastening bolt 340 through the first and second mounting holes 310, 320, and then screw it into the threaded hole 330. This not only reduces installation difficulty but also improves installation efficiency. Furthermore, due to its relatively simple and universal design, the lug locking structure 300 can be adapted to clutch cover 200 and housing 100 of varying sizes and shapes, increasing its practicality and application range. When the clutch cover needs to be disassembled or repaired, simply unscrewing the fastening bolt 340 eliminates the need for a complex disassembly process, reducing maintenance costs and time.

[0065] Example 3:

[0066] An embodiment of the present application provides a motorcycle clutch cover. In addition to the above-mentioned technical features, the motorcycle clutch cover of the embodiment of the present application also includes the following technical features.

[0067] like Figure 4 As shown, the ear locking structure 300 further includes:

[0068] Hidden groove 350, provided on the second ear 210;

[0069] The isolation protrusion 360 is disposed in the second hidden groove 350 , and a third mounting hole 370 communicating with the first mounting hole 310 is provided on the isolation protrusion 360 ;

[0070] The cover cap 380 is disposed on the isolation protrusion 360 and connected to the isolation protrusion 360 , and the cover cap 380 is provided with a limiting hole 381 communicating with the third mounting hole 370 ;

[0071] The diameter of the limiting hole 381 is the same as the diameter of the rod of the fastening bolt 340 .

[0072] In this embodiment of the present application, the design of the hidden groove 350 and the isolation protrusion 360 conceals some components of the lug locking structure 300, not only improving the clutch cover's aesthetics but also helping to reduce the impact of external factors on the lug locking structure 300, such as dust and moisture. Furthermore, the design of the cap 380 connected to the isolation protrusion 360 and the provision of a retaining hole 381 ensure that the fastening bolt 340 will not accidentally fall off during the tightening process. The diameter of the retaining hole 381 is the same as the diameter of the shank of the fastening bolt 340, further enhancing the reliability and safety of the lug locking structure 300.

[0073] Although the lug locking structure 300 includes components such as the hidden slot 350, the isolation protrusion 360, and the cap 380, the design of these components makes installation and maintenance relatively simple. During installation, the fastening bolt 340 simply needs to be passed through the limiting hole 381, the third mounting hole 370, the first mounting hole 310, and the second mounting hole 320, and then screwed into the threaded hole 330. During maintenance, the fastening bolt 340 can be removed and the cap 380 can be removed for necessary inspection and repair. Furthermore, because the cap 380 is connected to the isolation protrusion 360 and provided with the limiting hole 381, it helps prevent the fastening bolt 340 from loosening due to vibration or external forces during use, ensuring a tight connection and stability between the clutch end cover 200 and the housing 100.

[0074] Furthermore, the diameters of the first mounting hole 310 , the second mounting hole 320 and the third mounting hole 370 are the same, and gaps 390 are provided between the three and the fastening bolts 340 .

[0075] Because the diameters of first, second, and third mounting holes 310, 320, and 370 are identical to the shank diameter of fastening bolt 340, and a gap 390 is provided between them, wear caused by threaded fit is reduced. The presence of gap 390 also allows the bolts to move freely during installation and removal, thereby preventing wear and damage caused by excessive friction. The presence of gap 390 also simplifies the installation process. During installation, fastening bolt 340 can be more easily passed through the various mounting holes without becoming stuck or becoming difficult to rotate due to the tight threaded fit, improving installation efficiency and reducing potential damage caused by installation difficulties. Reduced wear and improved installation efficiency both help extend the life of the clutch cover and reduce maintenance costs and replacement frequency by reducing damage and the need for replacement due to wear.

[0076] Example 4:

[0077] An embodiment of the present application provides a motorcycle clutch cover. In addition to the above-mentioned technical features, the motorcycle clutch cover of the embodiment of the present application also includes the following technical features.

[0078] like Figure 4 As shown, an abutting inner ring 391 is provided in the gap 390 , an abutting outer ring 392 is provided on the fastening bolt 340 , and a spring 393 is provided between the abutting inner ring 391 and the abutting outer ring 392 . The spring 393 is located in the gap 390 and is sleeved outside the fastening bolt 340 .

[0079] In the embodiment of the present application, the preload force generated by the compression of spring 393 can significantly improve the locking effect between the clutch end cover 200 and the housing 100, helping to prevent the clutch cover from loosening due to vibration or external forces during use, thereby enhancing overall stability and reliability. Furthermore, the elastic force of spring 393 not only helps provide additional locking force during installation, but also assists during removal. When the fastening bolt 340 needs to be removed, the elastic force of spring 393 can help the bolt be more easily pulled out of the mounting hole, thereby improving removal efficiency. Furthermore, due to the presence of spring 393, the friction and impact forces experienced by the fastening bolt 340 during installation and removal are effectively alleviated, helping to reduce wear between the bolt and the mounting hole and extending its service life.

[0080] Furthermore, a limiting protrusion 394 is provided on the abutting inner ring 391 and the abutting outer ring 392 , and both ends of the spring 393 are connected to the limiting protrusion 394 .

[0081] In some embodiments of the present application, by providing limiting protrusions 394 on the abutting inner ring 391 and the abutting outer ring 392, and connecting the two ends of the spring 393 to these protrusions, the position of the spring 393 in the mounting hole can be effectively limited. This ensures that the spring 393 does not deviate from its predetermined path during the expansion and contraction process, thereby avoiding accidental contact between the spring 393 and the fastening bolt 340 or other components. At the same time, limiting the position of the spring 393 helps prevent the spring 393 from being damaged during installation, use, or disassembly. If the spring 393 is able to move freely or deviate from its predetermined path, it may rub or collide with surrounding components, causing damage. By fixing the position of the spring 393, this risk can be significantly reduced.

[0082] Although the design of limiting protrusion 394 has been added, this design does not increase the complexity of installation and maintenance. On the contrary, since the position of spring 393 is fixed, the installation and maintenance process is simpler and more intuitive. The design of limiting the position of spring 393 also helps to improve the safety of the clutch cover. If spring 393 can move freely during the extension and retraction process, it may interfere with surrounding components, causing potential safety hazards. By fixing the position of spring 393, this risk can be significantly reduced.

[0083] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved.
