The invention relates to a dual-motor speed control system. A first output shaft is arranged on the periphery of a second output shaft in a sleeving manner and is coaxial with the second output shaft; the first output shaft is selectively connected with the second output shaft through the output gear pair and the output gear shifting device; the intermediate gear pair at least comprises a first gear pair, a second gear pair, a third gear pair and a fourth gear pair; a first intermediate shaft of the first motor and a first intermediate shaft of the second motor are connected with a second output shaft through a first gear pair or a second gear pair; a first intermediate shaft of the first motor and a first intermediate shaft of the second motor are connected with a first output shaft through a third gear pair or a fourth gear pair, the two motors are independently or jointly used as a power source to provide power, and a plurality of gear shifting devices are connected with different intermediate gear pairs and output gear pairs. The speed change system can achieve switching among 15 different working modes, the requirement for multi-gear working of a conventional speed changer can be met, and transition gears can be provided to achieve unpowered gear shifting.

    本发明涉及一种双电机变速系统,第一输出轴套设于第二输出轴的外周且与其同轴设置;第一输出轴通过输出齿轮副及输出换挡装置与第二输出轴以可选择方式连接;中间齿轮副至少包括有第一齿轮副、第二齿轮副、第三齿轮副和第四齿轮副;第一电机第一中间轴和第二电机第一中间轴通过第一齿轮副或第二齿轮副连接第二输出轴;第一电机第一中间轴和第二电机第一中间轴通过第三齿轮副或第四齿轮副连接第一输出轴,双电机单独或共同作为动力源提供动力,通过多个换挡装置与不同中间齿轮副和输出齿轮副的接合,变速系统可以实现在15种不同工作模式之间的切换,既能满足常规变速器多挡位工作的需求,又能够提供过渡挡位以实现无动力换挡。
