Description

Technical Field

[0001] This utility model relates to the field of motorcycle gear shift drum sealing and protection technology, specifically a self-lubricating motorcycle gear shift drum sealing and protection device. Background Technology

[0002] The motorcycle shift drum is a crucial component of the motorcycle's transmission system, primarily used to enable gear changes. It's a transmission device installed between the motorcycle engine and the drive wheels, adjusting the engine's power output by changing the meshing position of the gears, thereby achieving different speeds and torque outputs. It typically works in conjunction with components such as the clutch and gearbox to facilitate gear shifting. During use, due to frequent gear changes, the shift drum is prone to deterioration in sealing performance and lubricant leakage, thus affecting its normal operation and reducing its lifespan.

[0003] Traditional motorcycle gearshift drum seals are prone to wear, deformation, and even aging due to frequent gear changes and environmental factors. More seriously, dust, impurities, and moisture can enter the gearshift drum through poorly sealed areas. These impurities mix with the lubricating oil, further accelerating wear on internal parts and reducing the drum's performance and lifespan. Secondly, insufficient lubrication is a major drawback of existing seals and protective devices. Current lubrication systems are often poorly designed, resulting in uneven and unstable lubricant supply. During high-speed operation of the gearshift drum, the demand for lubricating oil at various friction points is significant, but existing lubrication systems cannot deliver lubricating oil to these areas in a timely and effective manner. Therefore, self-lubricating motorcycle gearshift drum seals and protective devices are needed to address these issues. Utility Model Content

[0004] To address the issues that traditional motorcycle gearshift drum sealing devices are prone to wear, deformation, and even aging due to frequent gear shifting and environmental factors, this invention aims to provide a self-lubricating motorcycle gearshift drum sealing and protection device to solve the problems mentioned in the background. More seriously, external dust, impurities, and moisture can enter the gearshift drum through poorly sealed areas. These impurities mix with the lubricating oil, further accelerating the wear of internal parts and reducing the gearshift drum's performance and lifespan. Secondly, insufficient lubrication is a major deficiency in existing sealing and protection devices. Existing lubrication systems are often poorly designed, resulting in uneven and unstable lubricating oil supply. During the high-speed operation of the gearshift drum, the friction points require a large amount of lubricating oil, but existing lubrication systems cannot deliver lubricating oil to these points in a timely and effective manner.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model adopts a multi-layer sealing structure, including an outer sealing ring, an inner sealing ring, and an intermediate sealing layer. Microgrooves are provided on the inner and outer sealing rings to store lubricating oil, reduce friction, and improve seal life. The lubricating oil stored in the oil reservoir is evenly delivered to various friction points of the transmission drum through lubrication channels. The lubrication channels adopt a labyrinth design, which effectively prevents lubricating oil leakage while ensuring a continuous supply of lubricating oil, improving the sealing performance of the transmission drum. This effectively prevents lubricating oil leakage, reduces environmental pollution, and the self-lubricating system continuously provides lubricating oil, reducing friction, lowering energy consumption, and extending the service life of the transmission drum.
