Technical Field
[0001] This utility model relates to the field of motorcycle technology, and in particular to a novel transmission structure for widening the rear wheel of a motorcycle. Background Technology
[0002] When a motorcycle is in motion, assuming the pressure on the wheels and the roughness of the tire contact surface remain constant, the size of the contact area affects the amount of tire deformation, thus affecting grip. By appropriately widening the rear tire, the center of gravity of the entire vehicle is shifted above the rear wheel, which can improve the vehicle's load-bearing capacity and acceleration performance, and reduce the braking distance.
[0003] In existing motorcycles, the rear wheel support structure is a single-sided swingarm. Because its structural design differs from traditional motorcycles with double wishbones, an ABS system is incorporated into the rear wheel structure for safety during emergency braking. However, this design limits the space available in the single-sided swingarm support, preventing the tire from being widened. Consequently, the braking performance of the rear wheel and the vehicle's braking distance do not meet practical requirements. Therefore, those skilled in the art have provided a novel transmission structure for widening the rear wheel of a motorcycle to address the problems mentioned in the background. Utility Model Content

[0029] Specifically, the secondary transmission design significantly improves the compactness of the transmission system and effectively reduces space occupation. Within a limited space, through reasonable layout and structural design, efficient power transmission is achieved, providing strong support for the miniaturization and lightweighting of mechanical equipment. Secondly, the compact structural design does not sacrifice transmission efficiency; on the contrary, by optimizing the transmission path and reducing unnecessary energy loss, the secondary transmission makes power transmission smoother and improves overall transmission efficiency. This not only helps improve the working performance of mechanical equipment but also reduces energy consumption to a certain extent, achieving energy conservation and emission reduction. However, the compact structural design also brings some challenges. To ensure transmission stability, the front axle needs to tighten the chain. To address this issue, the designers cleverly used an eccentric worm gear to adjust the tension of the front drive chain. This innovative design allows the chain tension to be adjusted according to actual needs, thereby ensuring the stability and reliability of the transmission. In addition, an eccentric structure is also used at the rear wheel center to tighten the gap caused by the rearward movement of the front axle. This design, while widening the rear wheel, avoids the problem of ABS function loss. Widening the rear wheel not only improves the stability of the entire system but also... This design helps improve the smoothness and comfort of driving; it fully considers the needs of actual use, enabling mechanical equipment to meet performance requirements while also possessing higher reliability and durability. In summary, the design and application of secondary transmission plays a crucial role in mechanical equipment. Through reasonable structural design and optimization, the compactness, stability, and efficiency of the transmission system can be achieved. At the same time, this transmission method also has high flexibility and adjustability, which can meet the needs of different usage scenarios. In practical applications, by adopting technologies such as eccentric spiral plates and widened rear wheels, the performance and reliability of the transmission system can be further improved, providing a strong guarantee for the efficient operation of mechanical equipment.
[0030] Working Principle: By moving the power output wheel to the left side of the pulley aligned with the rear wheel, secondary transmission is achieved. This design makes the entire transmission system more compact, reducing space occupation and improving transmission efficiency. However, the compact structural design also brings some challenges, such as the need to tighten the chain on the front axle to ensure transmission stability. To solve this problem, the designers cleverly used an eccentric worm gear to adjust the tension of the front drive chain. The eccentric worm gear design allows the chain tension to be adjusted as needed, thus ensuring transmission stability and reliability. At the same time, an eccentric structure is also used at the center of the rear wheel to tighten the gap caused by the rearward movement of the front axle. This widens the rear wheel while avoiding the loss of ABS function. In addition, this design also fully considers… Practical application demands; widening the rear wheels not only improves the stability of the entire system but also contributes to enhanced ride smoothness and comfort. Simultaneously, by optimizing the transmission system design, mechanical equipment achieves higher reliability and durability while meeting performance requirements. In summary, the design and application of secondary transmissions play a crucial role in mechanical equipment. Through reasonable structural design and optimization, the compactness, stability, and efficiency of the transmission system can be achieved. Furthermore, this transmission method offers high flexibility and adjustability, meeting the needs of various application scenarios. In practical applications, employing techniques such as eccentric spiral plates and widened rear wheels can further improve the performance and reliability of the transmission system, providing strong support for the efficient operation of mechanical equipment.
