The invention discloses a multi-gear dual-motor hybrid electric vehicle and a transmission system thereof, the transmission system comprises a planetary gear structure, a first variable speed transmission structure, a second variable speed transmission structure and a final power output mechanism, the input end of the planetary gear structure is selectively in transmission connection or disconnection with an engine and a second motor; the first variable transmission structure comprises a first-gear transmission structure and a second-gear transmission structure which are independent from each other, and the output end of the planetary gear structure is selectively in transmission connection or disconnection with the first-gear transmission structure and the second-gear transmission structure; the input end of the second variable-speed transmission structure is connected with the first motor, and the output end of the second variable-speed transmission structure is in transmission connection with one of the second-gear transmission structure and the first-gear transmission structure; and the input end of the final power output mechanism is in transmission connection with the first-gear transmission structure and the second-gear transmission structure at the same time. By means of the transmission system, the problems that when a full dead axle gear structure runs and shifts gears, a pause feeling exists, and a two-gear ECVT power dividing mode is difficult to achieve are solved.

    本发明公开了一种多档化双电机混合动力汽车及其传动系统,该传动系统包括行星齿轮结构、第一变速传动结构、第二变速传动结构及最终动力输出机构,行星齿轮结构的输入端选择性地与发动机、第二电机传动连接或断开连接;第一变速传动结构包括相互独立的一档传动结构和二档传动结构,行星齿轮结构的输出端选择性地与一档传动结构、二档传动结构传动连接或断开连接;第二变速传动结构的输入端连接第一电机,其输出端与二档传动结构、一档传动结构中的一个传动连接;最终动力输出机构的输入端同时与一档传动结构、二档传动结构传动连接。该传动系统解决了全定轴齿轮结构行驶换挡时存在顿挫感、且难以实现2档ECVT功率分流模式的问题。
