Description
Technical Field
[0001] The present invention relates to the technical field of motorcycle driven disc accessories, and specifically relates to a connection structure of a driven disc for a motorcycle. Background Technique
[0002] The driven disc for a motorcycle is a key power transmission component, mainly used in the clutch system of a motorcycle. Its main function is to effectively transmit the power of the engine to the rear drive wheel, so as to achieve smooth acceleration and shifting. Usually, the driven disc is made of wear-resistant materials and has high strength and heat resistance to cope with the high temperature and friction generated during the operation of the motorcycle. The driven disc usually consists of multiple parts, including a driven disc body, a compression spring, a compression disc, and a connection structure, etc.
[0003] The existing connection structure of the driven disc for a motorcycle usually refers to the connection component between the driven disc and the compression disc. The compression disc is threadedly connected with the connection cylinder inside the driven disc by screws distributed in a ring shape, and the compression disc is slidably sleeved outside the connection cylinder. The setting of the screws can connect the compression disc and the driven disc while not hindering the elastic sliding of the compression disc. However, when installing and disassembling multiple screws, tools need to be used multiple times, which increases the operation time and it is impossible to install all the screws successfully at one time. Moreover, only using the screw installation method, the overall rigidity and stability are not good. For this reason, we propose a connection structure of a driven disc for a motorcycle. Summary of the Invention
[0004] The purpose of the present invention is to provide a connection structure of a driven disc for a motorcycle to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A connection structure of a driven disc for a motorcycle, including a driven disc body and a toothed disc. One side of the driven disc body is provided with a compression disc, and a connection disc is provided on the side of the compression disc away from the driven disc body. The toothed disc is arranged on the side of the connection disc away from the compression disc. An annularly distributed second through groove is opened inside the connection disc, and an installation mechanism is arranged inside the second through groove. Annularly distributed positioning cylinders are fixed on the inner wall of the driven disc body. The installation mechanism includes a sliding shaft that is threadedly sleeved with the second through groove. One end of the sliding shaft is fixedly connected with a gear, and the gear is meshed with the toothed disc. The end of the sliding shaft away from the gear is fixedly connected with an installation rod. A threaded portion is arranged on the outer side of one end of the installation rod. A rotating shaft is fixedly connected to the middle of the toothed disc, and a locking mechanism is connected to the end of the rotating shaft away from the toothed disc. The locking mechanism includes a turntable fixedly connected with the rotating shaft.
[0006] Preferably, the installation mechanism is connected to the positioning cylinder. An installation groove is opened inside the positioning cylinder, and thread strips are arranged on the inner wall of the installation groove close to the threaded portion.
[0007] Preferably, an annularly distributed chute is provided inside the turntable, and the rotating shaft passes through the middle of the connecting plate through a bearing.
[0008] Preferably, a fixing block is connected to the inner wall of the connecting plate close to the turntable, and a locking rod is slidably sleeved inside the fixing block.
[0009] Preferably, one end of the locking rod is fixedly connected to a slider, and the other end of the locking rod is fixedly connected to a lock block, and the slider is slidably sleeved with the chute.
[0010] Preferably, annularly distributed first through grooves are provided inside the pressing disc, and both the first through grooves and the pressing disc are slidably sleeved with the positioning cylinder, and a support spring is movably sleeved outside the positioning cylinder close to the first through grooves.
[0011] Preferably, a fixing plate is welded to the middle of the driven disc body, annularly distributed square blocks are connected to the outside of the fixing plate, and locking grooves are provided inside the square blocks.
[0012] Preferably, a main shaft connection hole is provided in the middle of the fixing plate and the driven disc body, a limiting rod is slidably sleeved inside the toothed disc, and a return spring is sleeved outside the limiting rod.

[0014] Preferably, one end of the limiting rod matches the size of the limiting hole, the locking groove and the lock block are in an insertion structure, and the lock block matches the size of the square groove.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. For the connection structure of the driven disc for motorcycles, by rotating the toothed disc to drive four gears to rotate simultaneously, the four gears drive the connection between the installation mechanism and the positioning cylinder, so that the pressing disc and the driven disc body can be quickly connected without installing screws one by one. The setting of the installation mechanism can facilitate quick disassembly and installation, save time and labor costs, and ensure that the force applied to the pressing disc is more evenly distributed, avoiding uneven force caused by individual installation, thereby reducing the risk of local stress concentration; 2. For the connection structure of the driven disc for motorcycles, while the installation mechanism is operating, the locking mechanism can be driven to operate.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0019] Please refer to Figures 1 - 10 , the present invention provides a technical solution: a connection structure of a driven disk for a motorcycle, including a driven disk body 1 and a gear disk 4. A pressing disk 2 is provided on one side of the driven disk body 1. An annularly distributed first through groove 9 is formed inside the pressing disk 2. Both the first through groove 9 and the pressing disk 2 are slidably sleeved with a positioning cylinder 7. A support spring 5 is movably sleeved outside the positioning cylinder 7 near the first through groove 9. A main shaft connection hole 18 is formed in the middle of the fixing plate 13 and the driven disk body 1.
[0020] For this connection structure of the driven disk for a motorcycle, when the pressing disk 2 is installed outside the driven disk body 1, the first through groove 9 is sleeved outside the positioning cylinder 7, and then the support spring 5 is placed into the first through groove 9 and sleeved outside the positioning cylinder 7. The support spring 5 is provided to ensure that the pressing disk 2 has the function of elastic sliding. The main shaft connection hole 18 is for connecting the power output shaft of the motorcycle engine and the driven disk body 1. This is the content of the prior art.
[0021] Please refer to Figure 1 、 Figure 3 and Figures 5 - 10 , a connection disk 3 is provided on the side of the pressing disk 2 away from the driven disk body 1. The gear disk 4 is arranged on the side of the connection disk 3 away from the pressing disk 2. An annularly distributed second through groove 19 is formed inside the connection disk 3. An installation mechanism 6 is provided inside the second through groove 19.
[0022] For this connection structure of the driven disk for a motorcycle, the connection disk 3 provides a supporting carrier for the installation mechanism 6, and the installation mechanism 6 is used for the connection between the pressing disk 2 and the driven disk body 1.
[0023] Please refer to Figure 1 、 Figure 3 and Figures 4 - 10, a positioning cylinder 7 distributed in a ring shape is fixed on the inner wall of the driven disk body 1. The installation mechanism 6 includes a sliding shaft 605 that is threadedly sleeved with the second through groove 19. One end of the sliding shaft 605 is fixedly connected with a gear 604, and the gear 604 is meshed with the tooth disk 4. The end of the sliding shaft 605 away from the gear 604 is fixedly connected with an installation rod 603. A threaded portion 602 is arranged on the outer side of one end of the installation rod 603. The installation mechanism 6 is connected to the positioning cylinder 7. An installation groove 601 is opened inside the positioning cylinder 7, and thread strips are arranged on the inner wall of the installation groove 601 close to the threaded portion 602.
[0024] For the connection structure of the driven disk for a motorcycle, after sleeving the first through groove 9 of the pressing disk 2 on the outer side of the positioning cylinder 7, then drive the installation rod 603 to insert into the installation groove 601 of the positioning cylinder 7 by the connection disk 3. Subsequently, rotate the tooth disk 4 to make the tooth disk 4 and the gear 604 meshed with each other. Then, the tooth disk 4 drives the four gears 604 to rotate simultaneously. The gear 604 drives the sliding shaft 605 to rotate, making the sliding shaft 605 and the second through groove 19 threadedly meshed. Subsequently, the sliding shaft 605 moves to one side in the second through groove 19. The sliding shaft 605 drives the installation rod 603 to rotate, so that the installation rod 603 drives the threaded portion 602 to rotate. The threaded portion 602 and the thread strips on the inner wall of the installation groove 601 are threadedly meshed. Subsequently, the installation rod 603 is connected to the installation groove 601. The installation rod 603 can limit the position of the pressing disk 2. The setting of the installation mechanism 6 can drive the four installation rods 603 to rotate simultaneously only by one rotational force, which is convenient for quick disassembly and installation, saves time and labor costs, and can ensure that the force applied on the pressing disk 2 is more evenly distributed, avoiding uneven force caused by individual installation, thereby reducing the risk of local stress concentration.
[0025] Please refer to Figures 6 - 9 and Figure 11 , a rotating shaft 12 is fixedly connected to the middle of the tooth disk 4. One end of the rotating shaft 12 away from the tooth disk 4 is connected with a locking mechanism 8. The locking mechanism 8 includes a turntable 804 fixedly connected with the rotating shaft 12. The rotating shaft 12 passes through the middle of the connection disk 3 through a bearing.
[0026] For the connection structure of the driven disk for a motorcycle, when the tooth disk 4 rotates, it will drive the turntable 804 to rotate through the rotating shaft 12, and the locking mechanism 8 can be driven to operate without setting an additional power structure.
[0027] Please refer to Figure 6 , Figure 7 , Figure 11 and Figure 12, an annularly distributed chute 805 is provided inside the turntable 804. A fixed block 801 is connected to the inner wall of one side of the connecting plate 3 close to the turntable 804. A locking rod 802 is slidably sleeved inside the fixed block 801. One end of the locking rod 802 is fixedly connected to a slider 803, and the other end of the locking rod 802 is fixedly connected to a locking block 20. The slider 803 is slidably sleeved with the chute 805. Annularly distributed square grooves 15 are provided on the inner wall of the pressing plate 2 close to the center. The chute 805 is arranged in an arc structure, and the locking rod 802 is arranged in an L shape.
[0028] For the connection structure of the driven disk for a motorcycle, first insert the locking block 20 into the square groove 15 of the pressing plate 2. When the turntable 804 rotates, it will drive the chute 805 to rotate. The arc surface of the chute 805 squeezes the slider 803, and the slider 803 slides along the chute 805. At the same time, the slider 803 drives the locking rods 802 to approach each other, and the locking rods 802 slide inside the fixed block 801. The fixed block 801 guides the sliding of the locking rods 802.
[0029] Please refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figures 10 - 12 , a fixing plate 13 is welded in the middle of the driven disk body 1. Annularly distributed square blocks 10 are connected to the outside of the fixing plate 13. Locking grooves 11 are provided inside the square blocks 10. The locking block 20 matches the size of the square groove 15, and the locking groove 11 and the locking block 20 are in an insertion structure.
[0030] For the connection structure of the driven disk for a motorcycle, the movement of the locking rod 802 will drive the locking block 20 to insert into the locking groove 11. While connecting the pressing plate 2 and the driven disk body 1 through the installation mechanism 6, the connecting plate 3 can be stably installed on the driven disk body 1. And the locking rod 802 passes through the square groove 15 of the pressing plate 2, which can guide the elastic sliding of the pressing plate 2, avoid the loosening and deviation of the pressing plate 2, and can strengthen the connection between the pressing plate 2 and the driven disk body 1, increase the rigidity of the entire driven disk structure, and improve the stability of the connection structure of the driven disk.
[0031] Please refer to Figure 1 , Figure 3 , Figure 8 and Figure 9 , a limiting rod 16 is slidably sleeved inside the inner side of the toothed disk 4. A return spring 17 is sleeved outside the limiting rod 16. Annularly distributed limiting holes 14 are provided on the surface of the connecting plate 3 around the rotating shaft 12. One end of the limiting rod 16 matches the size of the limiting hole 14, and the return spring 17 is made of alloy steel.
[0032] For the connection structure of the driven disc for a motorcycle, when it is necessary to rotate the toothed disc 4, an additional tool can be used to pull the limiting rod 16 outwards. The telescopic movement of the limiting rod 16 squeezes the return spring 17 against the inner wall of the toothed disc 4, causing the return spring 17 to contract. Then, one end of the limiting rod 16 disengages from the limiting hole 14, and then the toothed disc 4 is rotated, which can drive the installation mechanism 6 and the locking mechanism 8 to operate simultaneously. The axial elasticity of the return spring 17 can drive the limiting rod 16 to bounce back into the limiting hole 14. The return spring 17 is made of alloy steel, with relatively high strength and hardness. The annularly distributed limiting holes 14 facilitate the insertion of the limiting rod 16 and can limit the toothed disc 4, making the operation convenient.
[0033] In summary, when using the connection structure of the driven disc for a motorcycle, the pressing disc 2 is installed on one side of the driven disc body 1. First, the pressing disc 2 can be sleeved on the outside of the positioning cylinder 7, and then the connecting disc 3 drives the installation mechanism 6 to be connected to one side of the positioning cylinder 7. There is a certain distance between the connecting disc 3 and the pressing disc 2, which does not prevent the elastic movement of the pressing disc 2. At the same time, the locking mechanism 8 further strengthens the connection between the pressing disc 2 and the driven disc body 1, with convenient operation and time-saving installation. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
