Description
Technical Field
[0001] This utility model relates to the technical field of motorcycle engine drive shaft components, specifically a motorcycle engine drive shaft component. Background Technology
[0002] The driveshaft is the most important structure connecting the engine and the gearbox. When the engine is running, the output shaft transmits the force generated by the engine to the gearbox through the driveshaft. Then, through the cooperation of the engine, gearbox and constant velocity joint, the wheels are driven to rotate, thereby driving the entire vehicle to move. The driveshaft plays the role of energy transmission.
[0003] According to a novel motorcycle engine drive shaft component with application number 202323343776.7, an anti-loosening mechanism is provided. The mounting component is installed on the surfaces of the fixing component and the fixing screw cylinder through threaded engagement. Subsequently, the mounting component drives a positioning block to engage with the positioning slot. The engagement between the positioning block and the positioning slot prevents the mounting component from detaching from the surface of the fixing component. At this point, the mounting component moves a second magnet to contact the surface of the first magnet, ensuring stability during installation between the mounting component and the fixing screw cylinder. This achieves the anti-loosening function of the drive shaft component, resulting in higher stability during installation and preventing loosening during use, thus improving the performance of the drive shaft component.
[0004] However, although the aforementioned motorcycle engine drive shaft components are equipped with a release mechanism to prevent the drive shaft from detaching from the mounting component, their structural stability is poor. The mounting component and the fixing screw are only connected by threads, allowing the positioning block to engage in the positioning slot. This engagement method does not provide strong anti-torsional force during the operation of the drive shaft, so detachment is inevitable during the rotation of the drive shaft. Therefore, it still has certain shortcomings. In addition, the existing drive shaft outer gear generates a lot of heat during long-term transmission. Once the gear overheats, it will affect its strength and accelerate its wear rate, affecting its service life. The aforementioned drive shaft components do not have a function for cooling the drive gears, which is also a certain shortcoming. Therefore, we propose a motorcycle engine drive shaft component. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a motorcycle engine drive shaft component, which solves the problems mentioned in the background section.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a motorcycle engine drive shaft component, comprising a drive shaft body and a mounting connecting shaft, wherein the drive shaft body is mounted on one end of the mounting connecting shaft, and the top of the drive shaft body and the bottom of the mounting connecting shaft are provided with mutually cooperating anti-loosening mechanisms.
[0007] Furthermore, the anti-loosening mechanism includes a connecting threaded rod, a connecting threaded hole, a sliding ring, and several sliding pins. The connecting threaded rod is fixedly installed at one end of the drive shaft body. The connecting threaded hole is opened inside the end of the drive shaft body and is threadedly connected to the connecting threaded rod. Several sliding grooves are opened inside the outer side of the drive shaft body. Sliding rods are fixedly installed inside each of the sliding grooves. Springs are provided on the outer side of each of the sliding rods. The sliding ring is slidably sleeved on the outer side of the drive shaft body. Several sliding pins are fixedly installed inside the sliding ring. Several pin grooves are opened inside the outer side of the drive shaft body. The sliding pins cooperate with the pin grooves, and the sliding pins cooperate with the sliding rods and springs.
[0008] Furthermore, a number of transmission gears are provided on the outer side of the transmission shaft body, and each of the transmission gears is provided with a heat dissipation mechanism.
[0009] Furthermore, the heat dissipation mechanism includes a plurality of heat dissipation holes and heat dissipation guide plates, wherein the plurality of heat dissipation holes are opened inside the transmission gear, and the plurality of heat dissipation guide plates are fixedly installed inside the heat dissipation holes.
[0010] Furthermore, several of the aforementioned grooves are equally spaced inside the outer side of the drive shaft body, and several of the aforementioned pin grooves are equally spaced inside the outer side of the mounting connecting shaft.
[0011] Furthermore, the sliding pin has a hole inside that mates with the sliding rod.
[0012] Furthermore, several of the aforementioned heat dissipation holes are equally spaced inside the transmission gear.
[0013] Furthermore, several of the aforementioned heat dissipation guide plates are installed inside the heat dissipation holes at a 10° angle.
[0014] This utility model provides a motorcycle engine drive shaft component, which has the following advantages: 1. This motorcycle engine drive shaft component, through the setting of an anti-loosening mechanism, allows the drive shaft body to be connected to the mounting shaft during the process of connecting the drive shaft body. Only by pulling the sliding ring to move the sliding pin a certain distance from the outside of the sliding rod into the sliding groove, and then allowing the sliding pin to be fully moved into the sliding groove, the drive shaft body can be connected to the connecting threaded hole at one end of the mounting shaft through the connecting threaded rod. After the drive shaft body and the mounting shaft are threadedly connected through the connecting threaded rod and the connecting threaded hole, releasing the sliding ring allows the spring to return and push the sliding pin back to its original position, inserting the sliding pin into the pin groove. This allows the drive shaft body and the mounting shaft to be connected through the sliding pin, increasing its torsional resistance and connection stability, and making the connection convenient and quick.
[0015] 2. The motorcycle engine drive shaft component, through the setting of the heat dissipation mechanism, allows outside air to flow through the heat dissipation fins when the drive shaft body rotates and the drive gear rotates. This allows the air to flow through the heat dissipation holes, thereby dissipating the heat in the drive gear, reducing its temperature, slowing down its wear, and thus extending its service life.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0019] Please see Figures 1 to 7This utility model provides a technical solution: a motorcycle engine drive shaft component, including a drive shaft body 1 and a mounting connecting shaft 2. The drive shaft body 1 is installed at one end of the mounting connecting shaft 2. The top of the drive shaft body 1 and the bottom of the mounting connecting shaft 2 are provided with mutually cooperating anti-loosening mechanisms. By setting the anti-loosening mechanism, the torsional resistance of the connection between the drive shaft body 1 and the mounting connecting shaft 2 can be increased, and the connection can also be prevented from loosening. The installation is convenient and quick, and the stability after installation is better.
[0020] The anti-loosening mechanism includes a connecting threaded rod 3, a connecting threaded hole 4, a sliding ring 8, and several sliding pins 9. The connecting threaded rod 3 is fixedly installed at one end of the drive shaft body 1. The connecting threaded hole 4 is opened inside the end where the connecting shaft 2 is installed, and the connecting threaded hole 4 is threadedly connected to the connecting threaded rod 3. Several sliding grooves 5 are opened inside the outer side of the drive shaft body 1, and sliding rods 6 are fixedly installed inside each of the sliding grooves 5. Springs 7 are provided on the outer side of each of the sliding rods 6. The sliding ring 8 is slidably sleeved on the outer side of the drive shaft body 1. Several sliding pins 9 are fixedly installed inside the sliding ring 8. Several pin grooves 10 are opened inside the outer side of the connecting shaft 2, and the sliding pins 9 and pin grooves 10 are connected. The sliding pin 9 engages with the sliding rod 6 and the spring 7. By pulling the sliding ring 8, the sliding pin 9 is moved entirely into the sliding groove 5. When the sliding pin 9 is displaced, it compresses the spring 7. Then, the drive shaft body 1 and the mounting connecting shaft 2 are threadedly connected to the connecting threaded hole 4 through the connecting threaded rod 3. After the connection is completed, the spring 7 will rebound after the sliding ring 8 is released, thereby pushing the sliding pin 9 to reset and inserting it into the pin groove 10. After the sliding pin 9 is inserted into the pin groove 10, part of it is still located in the sliding groove 5. Thus, by having several sliding pins 9 located in the sliding groove 5 and the pin groove 10 respectively, the torsional resistance can be increased and its stability can be ensured. When the drive shaft body 1 rotates, it will not become loose.
[0021] A number of transmission gears 11 are provided on the outer side of the transmission shaft body 1, and a heat dissipation mechanism is provided inside each of the transmission gears 11. As a prior art technology, the transmission gears 11 are provided on the outer side of the transmission shaft body 1 and can mesh with the driven shaft gear for transmission. The heat dissipation mechanism can dissipate the heat accumulated inside the transmission gears 11, so as to avoid the situation where heat accumulates inside the transmission gears 11 and affects their strength.
[0022] The heat dissipation mechanism includes several heat dissipation holes 12 and heat dissipation guide plates 13. The heat dissipation holes 12 are opened inside the transmission gear 11, and the heat dissipation guide plates 13 are fixedly installed inside the heat dissipation holes 12. By setting the heat dissipation holes 12, air can pass through the interior of the transmission gear 11 when it rotates, thereby exchanging heat with the transmission gear 11 and removing the heat inside the transmission gear 11. The heat dissipation guide plates 13 can guide the air flow, allowing the air to flow quickly from the heat dissipation holes 12. At the same time, the heat dissipation guide plates 13 can exchange heat with the transmission gear 11. The heat dissipation efficiency is increased by the air flowing in the heat dissipation holes 12 and carrying away the heat on the heat dissipation guide plates 13.
[0023] Several sliding grooves 5 are equally spaced inside the outer side of the drive shaft body 1, and several pin grooves 10 are equally spaced inside the outer side of the mounting connecting shaft 2; the sliding grooves 5 and pin grooves 10 are set at fixed angles and spacings.
[0024] The sliding pin 9 has a hole inside that mates with the slide rod 6. By having a hole inside the sliding pin 9 that mates with the slide rod 6, the sliding pin 9 can slide on the outside of the slide rod 6. The sliding pin 9 can be removed from the outside of the slide rod 6 to replace the spring 7 on the outside of the slide rod 6, thus avoiding the spring 7 from losing its elasticity due to metal fatigue.
[0025] Several heat dissipation holes 12 are equally spaced inside the transmission gear 11; the evenly spaced heat dissipation holes 12 can dissipate heat evenly inside the transmission gear 11.
[0026] Several heat dissipation guide fins 13 are installed at an angle of 10° inside the heat dissipation hole 12; the angled arrangement of the heat dissipation guide fins 13 facilitates airflow.
[0027] In summary, when using this motorcycle engine drive shaft component, pulling the sliding ring 8 causes the sliding pin 9 to move completely into the sliding groove 5. When the sliding pin 9 is displaced, it compresses the spring 7. Then, the drive shaft body 1 and the mounting connecting shaft 2 are threadedly connected to the connecting threaded hole 4 through the connecting threaded rod 3. After the connection is completed, the sliding ring 8 is released, and the spring 7 will rebound, thereby pushing the sliding pin 9 to reset and inserting the sliding pin 9 into the pin groove 10. After the sliding pin 9 is inserted into the pin groove 10, part of it is still located in the sliding groove 5. Thus, by having several sliding pins 9 located in the sliding groove 5 and the pin groove 10 respectively, its torsional resistance can be increased, and its stability can be ensured. When the drive shaft body 1 rotates, there will be no loosening. When the transmission gear 11 rotates, air passes through its interior to exchange heat with the transmission gear 11 and remove the heat inside the transmission gear 11. The heat dissipation guide 13 can guide the air flow, allowing the air to flow quickly through the heat dissipation hole 12. At the same time, the heat dissipation guide 13 can exchange heat with the transmission gear 11. The heat dissipation efficiency is increased by the air flowing through the heat dissipation hole 12 and carrying away the heat on the heat dissipation guide 13.
[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
