A dual-motor hybrid gearbox comprises an input shaft suitable for being connected with an engine and a first motor; the output gear is mounted around the input shaft and is suitable for being connected with a second motor; the first planet row and the second planet row are arranged around the input shaft, compounded with each other and suitable for kinematic coupling and decoupling between the input shaft and the output gear. The first planet row comprises a first sun gear, a first gear ring, a first planet gear and a planet carrier bearing the first planet gear. The second planet row comprises a second sun gear, a second gear ring and a second planet gear. The second planet gear is also borne by the planet carrier, and the second sun gear is fixedly arranged on the first gear ring. The first planet row and the second planet row are provided with clutches and brakes, and the clutches and the brakes are configured to achieve at least two forward gear transmission ratios between the input shaft and the output gear through state combination of the clutches and the brakes. Various working modes of hybrid power can be realized through simple layout.
一种双电机混动变速箱包括:输入轴,适于与发动机和第一电机连接;围绕输入轴安装的输出齿轮,适于与第二电机连接;以及围绕输入轴布置且彼此复合的第一行星排和第二行星排,适于在输入轴与输出齿轮之间运动学耦合和脱离耦合。第一行星排包括:第一太阳轮、第一齿圈、第一行星轮、承载第一行星轮的行星架。第二行星排包括:第二太阳轮、第二齿圈、第二行星轮。第二行星轮也由行星架承载,第二太阳轮固定设置于第一齿圈上。第一行星排和第二行星排配备有离合器和制动器,离合器和制动器配置成通过它们的状态组合而实现输入轴与输出齿轮之间的至少两个前进挡传动比。能够以简单的布局实现混动各种工作模式。
