The invention discloses a hybrid four-gear transmission adopting double long-wheelbase motors. The transmission comprises a solid input shaft, a hollow input shaft, double clutches, an output shaft, adifferential, a first transmission mechanism and a second transmission mechanism, wherein the first transmission mechanism is arranged between the solid input shaft and the output shaft; and the second transmission mechanism is arranged between the hollow input shaft and the output shaft. The transmission further comprises a first motor and a second motor, wherein the first motor is connected with the differential through the second transmission mechanism, the second motor is directly connected with the differential, and the first motor and the second motor adopt high-speed high-efficiency long-wheelbase motors with the same wheelbase. According to the transmission, the two motors are arranged between the two ends of the solid input shaft in the axial direction, and the first motor is asclose to the input shafts as possible in the radial direction, so that the position of the differential is approximate to the position of a traditional transmission, the space change of an auxiliary frame of the whole vehicle is avoided as much as possible, and the length of a short half shaft of the differential is ensured to ensure the design and configuration of the included angle of a ball cage.

    本发明揭示了一种采用双长轴距电机的混动四挡变速器,包括实心输入轴、空心输入轴、双离合器、输出轴、差速器、第一传动机构以及第二传动机构,第一传动机构设置在所述实心输入轴和输出轴之间;第二传动机构设置在所述空心输入轴和输出轴之间;还包括第一电机和第二电机,第一电机通过所述第二传动机构与差速器连接;第二电机直连差速器,第一电机和第二电机采用具有相同轴距的高速高效长轴距电机。本发明通过两个电机在轴向方向上设置在实心输入轴的两端之间,第一电机在径向方向上尽可能紧邻输入轴,可以保证差速器位置与传统变速器位置近似,尽量避免整车副车架的空间更改,并确保差速器短半轴的长度以确保的球笼夹角的设计与配置。
