The invention discloses a multi-mode transmission special for hybrid power. The multi-mode transmission comprises an input shaft, a first planetary gear train, a second planetary gear train, an intermediate shaft, a differential mechanism, a first clutch, a second clutch, a first brake and a second brake. The input shaft is connected with an engine through a torque limiting shock absorber; the first planetary gear train comprises a sun gear A, a planet gear A, a planet carrier A and a gear ring A, the planet gear A is arranged between the sun gear A and the gear ring A and installed on the planet carrier A, and the planet gear A is meshed with the sun gear A and the gear ring A; the sun gear A is mounted on the input shaft; the second planetary gear train comprises a sun gear B, a planet gear B, a planet carrier B and a gear ring B. The invention has the beneficial effects that through the arrangement of the first clutch, the second clutch, the first brake and the second brake, the fixed connection mode of the first planetary gear train and the second planetary gear train is changed, static elements in the planetary gear trains are changed, and various transmission ratios are achieved under the condition that no extra gear pair is additionally arranged.
本发明公开了一种多模式混合动力专用变速器,包括输入轴、第一行星齿轮系、第二行星齿轮系、中间轴、差速器、第一离合器、第二离合器、第一制动器和第二制动器;所述输入轴通过限扭减振器与发动机相连;第一行星齿轮系包括太阳轮A、行星轮A、行星架A和齿圈A,行星轮A设于太阳轮A与齿圈A之间,且安装于行星架A上,行星轮A分别与太阳轮A和齿圈A啮合;太阳轮A安装于输入轴上;第二行星齿轮系包括太阳轮B、行星轮B、行星架B和齿圈B。本发明的有益效果为:设置第一离合器、第二离合器、第一制动器和第二制动器,通过改变第一行星齿轮系和第二行星齿轮系的固连模式,以及改变行星齿轮系中静止的元件,在不增设额外齿轮副的情况下实现多种传动比。
