The invention relates to an automotive double-cone pulley continuously variable transmission and belongs to the field of power transmission of motor vehicles. A main body comprises an input shaft, an input roller, a double-cone pulley bracket, a double-cone pulley, a rolling ring, a planet wheel, a sun wheel, an output planet carrier, a shell, an infinitely variable speed mechanism, a gear ring, an output shaft and a self-loading rolling body, wherein the input shaft, the input roller and the sun wheel are connected; the rolling ring is connected with the gear ring; the output planet carrier is connected with the output shaft; the double-cone pulley is arranged on the double-cone pulley bracket; and the double-cone pulley bracket can move along an axis direction of the input shaft. Parameters are reasonably designed, so that a transmission ratio range of the automotive double-cone pulley continuously variable transmission can meet the requirement of an automotive power transmission system. By the transmission, the infinitely variable speed can be realized, the whole transmission is compact in structure, members have a good stress state, an infinitely variable speed structure is simple, and is easy and convenient to control, the transmission efficiency is high, and the service life is long.
