下面参考图1-图6描述根据本申请实施例的动力传动系统1000，动力传动系统1000可以安装于车辆6000上。
如图1-图5所示，根据本申请实施例的车辆6000的动力传动系统1000包括：转换装置10、第一电机200、第二电机5000和发动机300。第一电机200和发动机300中的至少一个通过转换装置10用于选择性地输出动力至第一行驶端，第一行驶端可以为车辆6000的前车轮2000或者后车轮3000，本申请以第一行驶端为前车轮2000为例进行说明，也就是说，第一电机200可以通过转换装置10选择性地输出动力至第一行驶端，发动机300可以通过转换装置10选择性地输出动力至第一行驶端，第一电机200和发动机300可以同时通过转换装置10选择性地输出动力至第一行驶端，动力输出至第一行驶端后，车轮可以转动，实现车辆6000的行驶。发动机300用于通过转换装置10选择性地输出动力至第一电机200，也可以理解为，发动机300可以通过转换装置10输出动力至第一电机200，发动机300也可以不向第一电机200输出动力，发动机300通过转换装置10输出动力至第一电机200时，发动机300可以带动第一电机200发电。第一电机200可以用于通过转换装置10选择性地输出动力至发动机300，以带动发动机300起动点火。
当发动机300设置在转换装置10左侧时，在发动机300输出动力至第一行驶端时，发动机300的发动机输出轴301的转动方向与前车轮2000的转动方向相反，如图1所示，当发动机300设置在转换装置10右侧时，在发动机300输出动力至第一行驶端时，发动机300的发动机输出轴301的转动方向与前车轮2000的转动方向相同。第一电机200和发动机300中的至少一个通过转换装置10选择性地输出动力至行驶端的前车轮2000或后车轮3000时，例如：第一电机200和发动机300中的至少一个通过转换装置10选择性地输出动力至前车轮2000时，发动机300的发动机输出轴301的转动方向与前车轮2000的转动方向相同。作为一个实施例，在车辆6000的由后向前的方向上，发动机300设置在转换装置10的左侧，转换装置10与前轴车轮的前差速器600传动连接。通过将发动机300设置在转换装置10的左侧，能够使发动机300的发动机输出轴301的转动方向与前车轮2000的转动方向相反，由于发动机300的发动机输出轴301的转动方向与前车轮2000的转动方向相反，转换装置10与前差速器600之间不需要设置换向齿轮700，即可实现驱动前车轮2000转动效果，实现车辆6000的行驶，并且，通过切换第一电机200和/或发动机300通过同一个转换装置10选择性地输出动力至第一行驶端，且发动机300通过转换装置10选择性地输出动力至第一电机200，能够使车辆6000切换至不同的驾驶模式，提升车辆6000驾驶性能，同时，也能够简化动力传动系统1000结构，使动力传动系统1000结构紧凑。
并且，第二电机5000与发动机300传动连接以使得动力传动系统1000具有第一边驱动边发电模式，其中，在第一边驱动边发电模式情况下，第一电机200通过转换装置10将动力输出至第一行驶端，第二电机5000在发动机300驱动下发电。第二电机5000产生的电能可以供给第一电机200，节省动力传动系统1000的储能单元800内放电输出，并且，第二电机5000产生的电能可以供给储能单元800内存储，达到对储能单元800充电效果，从而提升动力传动系统1000保电能力，能够使车辆6000的电量得到补充，防止车辆6000发生电量不足的情况发生，有效避免影响车辆6000纯电驱动模式的使用。
由此，通过转换装置10、第一电机200和发动机300配合工作，第一电机200和发动机300通过同一个转换装置10选择性地输出动力至行驶端，动力传动系统1000不需要设置换向齿轮，可以简化动力传动系统1000结构，使动力传动系统1000结构紧凑，并且，通过切换第一电机200和/或发动机300通过同一个转换装置10选择性地输出动力至行驶端，且发动机300通过转换装置10选择性地输出动力至第一电机200，能够使车辆6000切换至不同的驾驶模式，提升车辆6000驾驶性能。另外，通过第二电机5000发电，能够使车辆6000的电量得到补充，防止车辆6000发生电量不足的情况发生，有效避免影响车辆6000纯电驱动模式的使用。
在本申请的一些实施例中，如图1所示，第二电机5000设置发动机300上，如此设置能够使第二电机5000和发动机300整体结构紧凑，便于第二电机5000和发动机300传动连接。
在本申请的一些实施例中，如图1所示，发动机300的发动机输出轴301与第二电机5000的第二电机输出轴2031平行，这样设置便于发动机300和第二电机5000传动连接。
