[0016] specific implementation plan
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0018] The present invention includes an input disc 14, an output disc 15, an axle speed regulating mechanism, a cone wheel speed change mechanism and a supporting guide device; the input disc 14 is connected with the sprocket drive mechanism, and the output disc 15 is connected with the output shell.
[0019] The axle speed regulating mechanism includes axle 1, gear speed regulating shaft 3, moving nut 2 and cone wheel slider 4; 3. Installed in the axle 1, the moving nut 2 passes through the through hole in the middle of the axle 1, and is installed on the gear speed regulating shaft 3 to form a spiral pair. When the driving gear speed regulating shaft 3 rotates, it drives the moving nut 2 in the middle of the axle 1 Axial movement in the through hole; the cone wheel slider 4 is divided into two parts, left and right, i...
