The variable-speed transmission system comprises an engine, a first motor, a second motor, an input shaft, an output shaft, a first synchronizer and a second synchronizer, the input shaft is connected with the engine, a first gear and a second gear are sleeved on the input shaft, the first synchronizer is connected with the input shaft, and the second synchronizer is connected with the output shaft. The input shaft is connected or disconnected with the first gear or the second gear through the first synchronizer. The output shaft is sleeved with a third gear and a fourth gear, the second synchronizer is connected with the output shaft, and the output shaft is connected or disconnected with the third gear or the fourth gear through the second synchronizer. A first motor shaft is connected with a fifth gear and a sixth gear, the fifth gear, the first gear and the third gear are in mutual transmission, and the sixth gear, the second gear and the fourth gear are in mutual transmission; the second motor shaft is connected with the output shaft through a transmission mechanism. The structure is simple and compact, gear shifting control devices are few, and the use cost is low; under the EV working condition, the two motors can simultaneously drive the output shaft; power gear shifting can be achieved under the EV working condition and the HEV working condition.

    本发明公开一种混合动力汽车的变速传动系统,包括发动机、第一电机、第二电机、输入轴、输出轴、第一同步器和第二同步器,输入轴连接发动机,输入轴上套有第一、第二齿轮,第一同步器连接输入轴,输入轴通过第一同步器分别与第一齿轮或第二齿轮形成连接或不连接;输出轴上套有第三、第四齿轮,第二同步器连接输出轴,输出轴通过第二同步器分别与第三齿轮或第四齿轮形成连接或不连接;第一电机轴与第五齿轮和第六齿轮连接,第五、第一、第三齿轮相互传动,第六、第二、第四齿轮相互传动;第二电机轴通过传动机构连接输出轴。本发明结构简单紧凑、换挡控制器件少,使用成本低;EV工况二电机可同时驱动输出轴;EV和HEV工况均可实现动力换挡。
