Motorcycle automatic shift actuator

Abstract

The invention relates to an automatic gear shifting executing mechanism of a motorcycle. The automatic gear shifting executing mechanism comprises an input shaft, a gear shifting shaft and a clutch arranged on the motorcycle, wherein the input shaft is connected with a gear shifting motor, a first gear drive pair is arranged between the input shaft and the gear shifting shaft, the input shaft is connected with a first ratchet shaft through a first ratchet mechanism, a reversing shaft is connected with a second ratchet wheel through a ratchet mechanism, the first ratchet mechanism or a second ratchet mechanism acts when the gear shifting is executed, and a fan-shaped gear is arranged on the reversing shaft and is meshed with a gear shifting shaft driven gear arranged on the gear shifting shaft to drive the gear shifting shaft to rotate so as to carry out a gear shifting action. According to the automatic gear shifting executing mechanism, the clutch and the gear shifting shaft are simultaneously controlled by adopting one motor, the delay (clutch separation-gear shifting action-clutch combination) required in a gear shifting process is ensured by installation positions of a cam profile of a transmission system and the fan-shaped gear, the control process is simplified, and the correct execution of the whole gear shifting process can be also ensured.

Description

technical field [0001] The invention relates to a motorcycle gear shifting device, in particular to an automatic gear shifting actuator for a motorcycle. Background technique [0002] In order to realize the automatic gear shifting of the motorcycle to reduce the difficulty of driving the motorcycle and achieve the purpose of energy saving and emission reduction, there are currently two technical solutions for realizing the automatic gear shifting of the motorcycle. 1. Tape-type CVT automatic transmission, this technical solution is generally applied to scooter motorcycles; 2, Gear-based automatic transmission, this technical solution is generally applied to heavy-duty motorcycles with large output power, and this technical solution is currently available Two technical branches, the first branch is the cooperation of traditional single clutch and shifting system to realize automatic shifting, the second branch is the mutual cooperation of dual clutch and shifting system to r...

AI Technical Summary

Problems solved by technology

[0003] Regarding the first technical branch of gear-based automatic transmissions, the gear transmissions that are widely used on motorcycles all adopt manual shifting, that is, through manual control of the clutch and shifting shaft, the two cooperate with each other to achieve shifting (mainly coordination of hands and feet), and the application of automobile automatic shifting technology to motorcycle transmissions, cost, volume / weight, layout, etc. will be insurmountable problems. The existing motorcycle automatic shifting technology basically uses two power components Control the clutch and the shift shaft separately. The disadvantage of this automatic shift technology is that when the clutch and the shift shaft are controlled separately through two power components, the system needs to detect whether the clutch is completely disengaged, whether the shift shaft action is completed, etc. And analyze and judge, and then through the control of the relevant power components to achieve the purpose of clutch and shift shaft action cooperation, this scheme requires the use of two prime movers, generally motors, and the timing of the clutch and shift shaft With control, the system is more complicated and the cost is higher
