Have the shaft shoulder on the described power output shaft, described jaw clutch pushes against away from the end face of the field of conjugate action and the step surface of the shaft shoulder; Described top is dialled mechanism and is comprised location fork, backing pin and ball; Described ball quantity is at least three; And all be positioned at the contact-making surface place of the jaw clutch and the shaft shoulder, all have the groove supporting on the jaw clutch end face at this contact-making surface place and the shaft shoulder step surface with ball; One end of described location fork is embedded on the outer circumference surface of jaw clutch, and the other end is enclosed within outside the backing pin, and described backing pin is connected on the reduction gearing.
The quantity of described ball is four, along the circumferential direction evenly distributes.
Described stopping means comprises stop collar and nut, and described nut thread is connected the end of power output shaft, and described stop collar is socketed on the power output shaft and between clutch gear and nut.
After adopting above structure, the utility model compared with prior art has the following advantages:
1) owing to realizes manual and electronic operation switching device shifter; Promptly top group mechanism is mounted on the jaw clutch, does not increase original volume, and simple in structure; Therefore; Compact overall structure, the quantity of part of having reduced, thus failure rate reduced, finally can reach the purpose of miniaturization;
2) in addition, replace original shifting fork mechanism, can realize the automatic operation of two-way clutch with the structure of jaw clutch and clutch gear and spring and ball; Need not other design operation mechanism comes manpower to push the motor deceleration gear aside; Therefore, simple to operate, simultaneously manual operating physical force is less.
