当动力选择装置处于中间位置时，第一输入轴的动力无法传递到输出轴、第二空心输入轴的动力通过变速箱第一级传动装置传递到中间轴、再通过第二级传动装置传递至输出轴；
当动力选择装置处于左侧位置、啮合第一啮合连接装置时，第一输入轴和变速箱第二空心输入轴通过动力选择装置耦合，两个变速箱输入轴的动力耦合后通过第一级传动装置传递到中间轴、再通过第二级传动装置传递至输出轴；
当动力选择装置处于右侧位置、啮合第二啮合连接装置时，第一输入轴和输出轴通过动力选择装置连接，第一输入轴的动力直接传递到输出轴上；第二空心输入轴的动力通过变速箱第一级传动装置传递到中间轴、再通过第二级传动装置传递至输出轴，两个动力在输出轴上耦合后输出。
