The invention provides a hybrid power transmission and an automobile. The hybrid power transmission includes a first countershaft assembly including a first countershaft constant mesh gear, a second countershaft assembly comprising a second countershaft constant mesh gear meshed with the first countershaft constant mesh gear and a driving gear used for outputting two gears by motor power, a thirdcountershaft assembly comprising a driven gear meshed with the two driving gears on the second countershaft assembly, and further comprising a third countershaft ring gear, a reverse gear shaft assembly including a reverse gear and a reverse gear shaft ring gear, and a differential assembly comprising a differential ring gear. A synchronizer is arranged between two driven gears on the third countershaft assembly; the differential ring gear is meshed with the output shaft ring gear, the reverse gear shaft ring gear and the third countershaft ring gear at the same time. According to the scheme,the transmission ratio is increased, torque output is increased, and model selection of the motor is facilitated; by lengthening the transmission path, the arrangement of the motor is facilitated.

    本发明提供了一种混合动力变速器及汽车。该混合动力变速器包括:第一中间轴总成,包括第一中间轴常啮合齿轮;第二中间轴总成,包括第二中间轴常啮合齿轮、用于电机动力输出两个档位的主动齿轮;其中第二中间轴常啮合齿轮与第一中间轴常啮合齿轮相啮合;第三中间轴总成,包括与第二中间轴总成上的两个主动齿轮相啮合的从动齿轮,还包括第三中间轴环齿;第三中间轴总成上的两个从动齿轮之间设有同步器;倒档轴总成,包括倒档齿轮和倒档轴环齿;差速器总成,包括差速器环齿;其中差速器环齿同时与输出轴环齿、倒档轴环齿和第三中间轴环齿相啮合。上述方案,通过增大传递比,增大扭矩输出,便于电机的选型;通过增长传递路径,便于电机的布置。
