Embodiment 1
[0091] Working principle of embodiment one:
[0092] When the disengagement mechanism 4 is locked and positioned, the locking ring gear 32 cannot rotate circumferentially; when the drive pinion 37 drives the long planetary gear 353 to rotate, the long planetary gear 353 meshes and rotates against the locking inner tooth 323, because the long planetary gear 353 and the locking inner tooth Teeth 323 mesh with transmission ratio internal teeth 332 at the same time, and the number of teeth of long planetary gear 353, the number of teeth of locking ring gear 32, and the number of teeth of transmission ratio ring gear 33 are all fixed numbers and the axis center of long planetary gear 353 will not occur. change, so when the long planetary gear 353 rotates one circle along the locking ring gear 32 and returns to its original position, the number of teeth that the long planetary gear 353 has rotated on the locking ring gear 32 is the same as the number of teeth that the long planetary ...
