The invention discloses an internal contact conical ring type continuously-variable transmission. Two conical wheels are in internal contact with two conical rings respectively, the stress of a contact area is small, and the service life can be improved. Meanwhile, the reliability is high and the power transmission efficiency is high. The continuously-variable transmission comprises a shell, an input shaft, a planetary line, the input conical wheel, the conical rings, the output conical wheel, an output shaft, a differential mechanism, an output gear, a loading mechanism and a speed changing mechanism, wherein the input shaft, the planetary line, the input conical wheel, the conical rings, the output conical wheel, the output shaft, the differential mechanism, the output gear, the loading mechanism and the speed changing mechanism are located in the shell. Power is transmitted between the output conical wheel and the input conical wheel through the conical rings which are arranged outside the two conical wheels in a sleeved mode. The loading mechanism is a hydraulic-mechanical loading mechanism formed by coupling a hydraulic part and a mechanical part. The speed changing mechanism is of a structure similar to a bearing, and speed changing is realized by pushing an outer ring to drive the conical rings.
