The invention discloses a transmission, a drive axle system and a vehicle. The transmission comprises a first gear and a second gear which are arranged on a first output shaft in an empty sleeving mode, and a first motor is used for driving the first output shaft to rotate; the first synchronizer is selectively in transmission connection with the first gear or the second gear; the third gear and the fourth gear are hollowly sleeved on the second output shaft; the second motor is used for driving the second output shaft to rotate; the second synchronizer is selectively in transmission connection with the third gear or the fourth gear; the third output shaft is used for driving the differential mechanism to rotate. The axis of the third output shaft coincides with the rotating axis of the differential mechanism. The fifth gear is meshed with the first gear and the third gear, and the sixth gear is meshed with the second gear and the fourth gear. According to the transmission, various different speed ratios can be switched to transmit the rotating speed and the torque, meanwhile, the problem of gear shifting power interruption is avoided, the use experience of a user is improved, the structure is compact, the occupied space is small, the fault rate is reduced, and the overall performance is effectively improved.

    本发明公开了一种变速器、驱动桥系统和车辆,变速器包括:第一齿轮和第二齿轮空套于第一输出轴上,第一电机用于驱动第一输出轴转动;第一同步器可选择地与第一齿轮或第二齿轮传动连接;第三齿轮和第四齿轮空套于第二输出轴上,第二电机用于驱动第二输出轴转动;第二同步器可选择地与第三齿轮或第四齿轮传动连接;第三输出轴用于驱动差速器转动,第三输出轴的轴线与差速器的转动轴线重合;第五齿轮与第一齿轮和第三齿轮啮合,第六齿轮与第二齿轮和第四齿轮啮合。根据本发明的变速器,能够切换多种不同的速比以传递转速与扭矩,同时避免换挡动力中断的问题,提高用户的使用体验,且结构紧凑,占用空间小,降低了故障率,有效提高整体性能。
