The invention discloses a planetary intelligent self-adaptive two-gear multi-cam automatic speed change driver which comprises a power device, a box body, a transmission shaft, a planetary transmission mechanism, a circular ring body axial outer conical sleeve and a circular ring body axial inner conical sleeve, wherein the transmission shaft is sleeved by the circular ring body axial outer conical sleeve which is transmitted by a helical cam pair; and the planetary transmission mechanism adopts a slow gear transmission mode and has a multi-end-face-cam transmission structure. The planetary intelligent self-adaptive two-gear multi-cam automatic speed change driver has all the advantages of existing cam self-adaptive automatic speed change devices and outputs slow gear power through the planetary transmission mechanism; by adopting the multi-end-face-cam slow gear transmission structure, the transmission efficiency is improved, the sensitivity during gear shifting can be guaranteed, sudden jerk and clamping stagnation which are caused by gear shifting can be eliminated, and the driving and riding comfortableness is improved; and furthermore, energy is saved, consumption is reduced, and the dynamic property, the economical property, the driving safety and the comfortableness of vehicles are greatly improved.
