Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Fig. 1 ~ 9, the utility model mainly comprises manual clutch handle 2 and clutch mainboard 3, and bearing bore through before and after clutch mainboard 3 is provided with, is provided with clutch shaft bearing 4 in bearing bore.
Clutch shaft bearing 4 center is provided with clutch block installation cavity, is provided with clutch block 6 in clutch block installation cavity, and clutch block 6 both sides are provided with clutch block gear pin 7.Clutch shaft bearing 4 dorsad clutch mainboard 3 side is provided with two bearing grooves 5.The clutch block gear pin 7 of clutch block 6 both sides is positioned at two bearing grooves 5, and clutch block gear pin 7 stops by clutch shaft bearing 4 cannot to clutch mainboard 3 one lateral movement, can to clutch mainboard 3 one lateral movement dorsad.
Clutch shaft bearing 4 is provided with cam 9 in clutch mainboard 3 side dorsad, cam 9 median plane is provided with cam sleeve 10 to clutch shaft bearing 4 side, be provided with spring 8 in cam sleeve 10, spring 8 end thereof contacts cam 9, clutch block 6 is pressed in the clutch block installation cavity of clutch shaft bearing 4 by the other end.Described cam sleeve 10 both sides are provided with the sleeve clutch groove 11 that clutch block gear pin 7 can be allowed to enter smoothly.
Under electric clutch state, clutch shaft bearing 4 connects drive by the electric driving mechanism 1 be arranged on clutch mainboard 3, and cam 9 is rotated with clutch shaft bearing 4 by clutch block 6.Described electric driving mechanism 1 comprises motor 1.1, and motor 1.1 output is provided with drive sprocket 1.2, and drive sprocket 1.2 connects the driven sprocket 1.4 driving and be arranged on clutch shaft bearing 4 outer ring by driving chain 1.3.
Under manual clutch state, manual clutch handle 2 stretches in the clutch block installation cavity of clutch shaft bearing 4 through clutch mainboard 3, overcomes spring 8 pressure and is pressed in the cam sleeve 10 of cam 9 by clutch block 6.Manual clutch handle 2 front end is provided with manual clutch fixture block 13, and while pressure clutch block 6, manual clutch fixture block 13 enters sleeve clutch groove 11, thus manually clutch handle 2 is with moving cam 9 to rotate.Manual clutch handle 2 rear end is provided with the handle 12 vertical with manual clutch handle 2, is convenient for people to rotate dynamic clutch handle 2 and carries out manual clutch.
