Independent speed changing mechanism of motorcycle

Abstract

The invention discloses an independent speed changing mechanism of a motorcycle, which comprises a speed changer and a shift drive assembly. The speed changer is arranged in a cabinet of the independent speed changer, and a clutch and an engine of the motorcycle are arranged outside the cabinet. The speed changer, the engine and the clutch are arranged side by side along the longitudinal direction. The speed changer shifts gear through the shift drive assembly. The shift drive assembly comprises a shift drum, a shift fork and a shift drive rod which is driven by a motorcycle shift pedal. The shift drive rod and the shift drum are driving fitted by an interlaced shaft. The invention makes full use of other effective space of the motorcycle, and improves the lubricating condition of the speed changer, and also prolongs the service life of the speed changer even in large torque. The speed changer can be directly disassembled and the engine can directly drive other mechanism. The inventionis energy-saving, simple and shortcut to be operated, and can avoid long period running of the speed changer, thereby reducing the costs of usage and maintenance; simultaneously, the interlaced shaftdriving is adopted as a driving mode, so that the outside driving mode of speed changer shifting gear does not need to be changed.

Description

technical field [0001] The invention relates to a motorcycle power transmission device, in particular to an independent speed change mechanism of a motorcycle. Background technique [0002] Motorcycle is a relatively commonly used means of transportation and transportation. It is a two-wheeled or tricycle that steers the front wheels by the handle. Motorcycles have the advantages of being cheap, light, flexible, and fast-moving. They can reach mountainous areas and rural areas where large-scale vehicles cannot reach, and they are widely used. [0003] Motorcycles include wheels, frames and power and transmission systems. Power and transmission systems are important devices for motorcycles. The performance and operating status of the devices directly affect the overall performance of motorcycles. [0004] In the prior art, in order to adapt to its own advantages and characteristics, the manufacturing process of motorcycles focuses on portability and reduced volume. Therefore...

Problems solved by technology

[0005] However, the traditional motorcycle power and transmission system is integrated with the engine and the transmission, and the heat from the engine is transferred to the lubricating oil, resulting in poor lubrication of other operating mechanisms (such as the gear meshing pair of the transmission) and reducing the service life of the friction pair. ; At the same time, the same type of lubricating oil is used, but according to the principle of lubrication, the engine and transmission need different types of lubricating oil in order to achieve the purpose of good lubrication

Obviously, the traditional power and transmission structure cannot guarantee the good running state of the motorcycle power and transmission system only from the perspective of lubrication. Poor, greatly reducing the life of the transmission

Moreover, existing motorcycles have diversified uses, and the engine can also be used to drive other machines such as water pumps and rotary tillers. The existing motorcycle power and transmission system can only output power through the transmission, increase the transmission chain, and drive water pumps, etc. The transmission efficiency will be greatly reduced during mechanical operation, which not only wastes energy, but also makes the transmission run for a long period of time in a poor lubrication environment, reducing the service life of the transmission and increasing operating costs
