Abstract: The present invention discloses an electromechanical compound transmission device for a tracked vehicle. The electromechanical compound transmission device includes a front transmission mechanism, a power coupling mechanism, an independent drive mechanism, and convergent planetary gearsets arranged on both sides of the power coupling mechanism. The present invention can not only implement driving, steering, and other functions of a vehicle, but also provide sufficient electric energy for a vehicle-mounted device. In other words, a series mode can be adopted to satisfy a torque output requirement, and is mainly used for low and medium-low speed driving, as well as reverse driving and climbing steep slopes; and a series-parallel mode can also be adopted to satisfy requirements of high and medium-high speed driving, and can achieve relatively high transmission efficiency and fuel economy.
