Abstract

A planetary gear train transmission device of a hybrid vehicle is provided, which belongs to the technical field of transmissions. A transmission device of a hybrid vehicle based on a planetary gear train, which has a simple structure and is convenient to maintain is provided. The transmission device is composed of two motors, two clutches, one simple planetary gear train, and one complex planetary gear train. One motor is mainly used for generating power, and the other motor is used for driving the vehicle to move forward and brake to recover energy. Selection of different speed ratios and different working modes can be achieved by means of different combinations of the clutches and the planetary gear trains and different working states of the engine and the two motors. The present disclosure is convenient to control, has a compact structure, and adopts a few of parts.
