  "textContent": "A transmission device for a power system, comprising a first electric motor (EM), a second electric motor (EM), a single planetary gear train (PG), and a reduction gear transmission mechanism. The transmission device is provided with a brake (B) and two clutches (C C) and is capable of achieving the electric motor driving mode of two gears and satisfying low-speed high-torque and high-speed usage requirements of electric motor driving. During hybrid power driving, an input power splitting and fixed speed ratio mode is adopted to achieve high-efficient operation of the power system. By removing components such as clutches connected to an engine, the transmission device can also be used as a dual-motor two-gear electric motor drive transmission.",
