Provided is a drive axle system driven by a single motor, comprising: a single motor power unit for transmitting power of the single motor to a first-gear driven gear and a second-gear driven gear; the first-gear driven gear is used for receiving power from the single-motor power unit; the second-gear driven gear is used for receiving power from the single-motor power unit; a joint gear sleeve is arranged in the middle of the gear shifting gear sleeve connecting shaft in a sliding mode, and the first-gear driven gear and the second-gear driven gear are arranged on the gear shifting gear sleeve connecting shaft in a relatively rotating and sleeving mode; the differential mechanism is connected to one end of the gear shifting gear sleeve connecting shaft through a differential mechanism shell so as to be used for receiving power from the gear shifting gear sleeve connecting shaft and outputting the power to a first power output half shaft and a second power output half shaft, the first power output half shaft is arranged in the gear shifting gear sleeve connecting shaft in a penetrating mode and extends to be connected to the first planet row, and the second power output half shaft is connected to the second planet row. The second power output half shaft is connected to the second planet row. The drive axle is compact in structure, gear shifting impact can be reduced, and driving control comfort is improved.

    提供了一种由单电机驱动的驱动桥系统,包括:单电机动力单元,用于将单电机的动力传递至一挡从动齿轮和二挡从动齿轮;一挡从动齿轮,用于接收来自单电机动力单元的动力;二挡从动齿轮,用于接收来自单电机动力单元的动力;换挡齿套连接轴,中部可滑动地设置有接合齿套,所述一挡从动齿轮和二挡从动齿轮可相对转动地套设于该换挡齿套连接轴;以及差速器,通过差速器壳体连接于换挡齿套连接轴的一端以用于接收来自换挡齿套连接轴的动力,并将该动力输出至第一动力输出半轴和第二动力输出半轴,第一动力输出半轴穿设于换挡齿套连接轴内并延伸连接至第一行星排,第二动力输出半轴连接至第二行星排。该驱动桥结构紧凑,可降低换挡冲击,提高驾驶操控舒适性。
