The invention discloses a gearbox for hybrid power. The gearbox for hybrid power comprises an input shaft, an output shaft, a first transmission mechanism connected with a motor and the output shaft, a second transmission mechanism connected with the input shaft and the output shaft, and a third transmission mechanism connected with a generator and the output shaft, wherein the input shaft is connected with a first clutch, the generator is connected with a second clutch, and the first clutch and the second clutch are connected with an engine. The gearbox for hybrid power is simple in structure and clear in gear shifting logic. Under the condition of sufficient electric quantity, dual-motor driving can be realized; common driving of the engine and the motor can be realized; under the condition of insufficient electric quantity, range extending mode driving can be achieved, namely, the engine drives the generator to generate electricity, and the generated electric quantity is input into the motor to drive the vehicle; in the pure engine driving mode, whether the generator is driven to generate electricity or not can be judged according to the electric quantity; and meanwhile, the parking power generation function is achieved.
本发明公开了一种用于混合动力的变速箱,包括输入轴、输出轴、与电动机和所述输出轴连接的第一传动机构、与所述输入轴和输出轴连接的第二传动机构以及与所述发电机和输出轴连接的第三传动机构,输入轴与第一离合器连接,发电机与第二离合器连接,第一离合器和第二离合器与发动机连接。本发明用于混合动力的变速箱,结构简单,换挡逻辑清晰。在电量充足的情况下可以实现双电机驱动;还可以实现发动机和电动机共同驱动;在电量不足的情况下还可以实现增程模式驱动,即发动机驱动发电机发电,产生的电量输入电动机进而驱动车辆;在纯发动机驱动的模式下可以根据电量的多少判断是否驱动发电机发电;同时具备驻车发电功能。
