Automatic variable speed control system for motorcycle

Abstract

The invention discloses an automatic variable speed control system for a motorcycle. The system comprises an automatic variable speed control unit, an electric gear shifting actuator and a throttle control and execution unit, wherein the electric gear shifting actuator comprises a gear shifting motor, a reducing gear and a variable-speed shaft, the gear shifting motor drives the variable-speed shaft to execute a gear shifting operation by virtue of transmission of a sector gear on the variable-speed shaft and the reducing gear; the throttle control and execution unit controls a throttle to close and open; the automatic variable-speed control unit controls the electric gear shifting actuator to execute a gear shifting operation, the throttle control and execution unit receives an oil return instruction before the gear shifting operation is executed, and the opening degree of a throttle is reduced, thus rotating speed of an engine is reduced to reduce gear shifting and speed changing impact; after the gear shifting operation is finished, the opening degree of the throttle is adjusted according to gear condition. The automatic variable speed control system disclosed by the invention has the advantages that the original structure of a common motorcycle engine is used effectively so that the motorcycle engine has an automatic gear shifting function, the overall structure is simple and compact, and arrangement is reasonable. The automatic variable speed control system disclosed by the invention keeps the advantages of high efficiency and low cost of the original motorcycle.

Description

technical field

[0001] The invention relates to an automatic variable speed control system of a motorcycle. Background technique

[0002] With the development of motorcycle technology, users have put forward higher requirements for the motorcycle itself, hoping that the motorcycle should not only be easy to drive and operate, but also energy-saving, environmentally friendly and fuel-efficient. At present, ordinary motorcycles (underbone bikes and knight bikes) on the market must manually shift gears when riding, so that the driving maneuverability needs to be judged subjectively by humans when shifting gears, and it requires considerable coordination of hands and feet to shift gears smoothly. , there are certain difficulties for most women or inexperienced drivers; the existing centrifugal continuously variable transmission (CVT) motorcycles do not require manual shifting when riding, but there are also low transmission efficiency and fuel consumption. High efficiency, high...
