The invention discloses a hybrid-power transmission which comprises an input shaft assembly, an output shaft assembly, a reverse gear shaft assembly and a differential, wherein the input shaft assembly comprises an input shaft and a plurality of driving gears which are arranged on the input shaft; the output shaft assembly comprises an output shaft; a plurality of driven gears are arranged on the output shaft; corresponding driving gears and driven gears are in meshing transmission, so that gear sets at different gears are formed; the reverse gear shaft assembly comprises a first reverse gear shaft and a second reverse gear shaft; an E-gear synchronizer which can separate or combine two reverse gear shafts is arranged between the first reverse gear shaft and the second reverse gear shaft; the first reverse gear shaft and the output shaft are in constant mesh transmission with the differential respectively; the second reverse gear shaft is in meshing transmission connection with the output shaft optionally; the hybrid-power transmission further comprises a motor transmission mechanism; and the second reverse gear shaft is in constant mesh transmission with the motor transmission mechanism. The invention aims to provide the hybrid-power transmission which can achieve single-motor parking charge; when an engine drives the hybrid-power transmission independently, the motor transmission mechanism can be separated; and at the same time, the cost is low.
