Specific embodiment
The technical solution of the utility model is further illustrated below in conjunction with the accompanying drawings and by specific embodiment.
Refer to shown in Fig. 1 to Fig. 5, in the present embodiment, a kind of arrangement of clutch for motor-operating mechanism includes clutch
Device gear 1, ratchet 2, pull-fork assembly, clutch shaft 3 and manual shaft 4, the assembling of the clutch gear 1, ratchet 2 and pull-fork assembly
On the clutch shaft 3, the pull-fork assembly includes the shift fork gear 5 being structure as a whole and two shift forks 6, the manual shaft
The manual actuation gear 7 being meshed with the shift fork gear 5 is provided with 4, the shift fork gear 5 is arranged at described two shift forks
5 side, the shift fork gear 5 are rotationally assemblied on the clutch shaft 3 by bearing 8, and the side of the bearing 8 leads to
Cross shaft block ring carry out it is spacing.
The ratchet 2 is arranged in the clutch gear 1, and which includes ratchet body 20, and the ratchet body 20 passes through
Centre bore 21 is fixed on the clutch shaft 3 using keyway, and the side of the ratchet body 20 is limited by shaft block ring
Position, and the outer rim of the ratchet body 20 is symmetrically arranged with two secter pats 22, the ratchet sheet of 22 both sides of described two secter pats
20 outer rim of body offers wedge surface 23, and the wedge surface 23, the side wall of secter pat 22 form wedge with the inwall of the clutch gear 1
Groove 24, the wedge groove 24 amounts to four, respectively positioned at the both sides of two secter pats 22, is movably disposed in the wedge groove 24
There is needle roller 9, and the needle roller 9 is limited by the wedge groove 24 and cannot roll out wedge groove 24, the needle roller 9 and the secter pat 22
Spring 10 is provided between the wall of side, described two shift forks 6 are inserted between the ratchet body 20 and clutch gear 1, and are located at
Between two wedge grooves 24 of homonymy, the clutch gear 1 is meshed with driven gear 11, the driven gear 11 and motor shaft
Gear 12 is meshed.
The ratchet body 20 is circular configuration, and described two shift forks 6 are the circle for coordinating the ratchet body 20 to arrange
