所述换档齿轮1从左倒退档切换齿轮32脱齿后滑动至换档齿轮运动段211的右端与右边齿轮413齿合连接时输出传动前进档；所述换档齿轮1滑动到换档齿轮运动段211中间既不与左倒退档切换齿轮32齿合连接，也不与右边齿轮413齿合连接为空档。
所述差速器A连接有左右后桥7，左右后桥7包括左右半轴管71及左右半轴72，左右半轴72穿接固定于左右半轴管71内，所述左右半轴管71的两端分别固定有轮毂73；所述左右半轴管71的左半轴管与基壳件A12的左侧固定连接，右半轴管与右壳盖A12右侧固定连接；所述动力输出传动齿轮5的左侧端头穿接固定在基壳件A12通孔上、右侧端头穿接固定在右壳盖A13的通孔上，左右半轴72穿接固定于左右半轴管71内与对应的动力输出传动齿轮5的左右侧端头固定连接；所述电机动力输入连接端21连接有变频电机211；所述机动动力输入连接端22与发动机传动机构连接，发动机传动机构为离合器组件201或传动带或传动链或传动轴组件；所述电机动力输入连接端21穿过基壳件A12伸出在发动机传动机构布置腔A2上，机动动力输入连接端22穿出右壳盖A13外与变频电机211的电机轴连接，变频电机211固定在右壳盖A13外壁。
所述换档传动机构6包括动力输入旋转轴61及滑动换档架62；所述齿轮腔A1的顶部设有旋转轴孔63(旋转轴孔63设于基壳件A12顶部)，动力输入旋转轴61穿接在旋转轴孔63上，轴头穿出在基壳件A12外顶部；所述齿轮腔A1内设有滑动换档架穿接杆64，滑动换档架穿接杆64横向固定于齿轮腔A1内壁(滑动换档架穿接杆64横向固定连接于基壳件A12)；所述动力输入旋转轴61的底端连接有旋转摆动横杆611，旋转摆动横杆611的尾端向下延伸有换档架拨动杆612；所述滑动换 档架62包括横杆621，横杆621的一端设有换档架连接杆穿接孔622，另一端连接有换档齿轮连接件623，换档齿轮连接件623卡入在换档传动机构连接件12的环绕凹槽121上与其活动连接，滑动换档架62通过换档架连接杆穿接孔622穿接在滑动换档架穿接杆64上，横杆621的顶部设有用于换档架拨动杆612穿入的长方形的矩形孔624，换档架拨动杆612插入在矩形孔624内接触性连接，动力输入旋转轴61旋转拨动滑动换档架62整体沿滑动换档架穿接杆64左右滑动行走而拉动换档齿轮1左右滑动实施前进档、空档、倒退档切换，矩形孔624提供换档架拨动杆612行程所需要的活动距离空间；换档时，外部的换档杆(换档脚踏)换档时会拉动动力输入旋转轴旋转，旋转摆动横杆随之左右摆动旋转，旋转摆动横杆通过换档架拨动杆拉动滑动换档架左右滑动，滑动换档架通过移动位置带动换档齿轮左右滑动，使换档齿轮在前进档、倒退档、空档之间切换实现换档齿轮的换档工作。
前进档的换档过程：
变频电机及发动机传动机构工作时都是驱动混合动力输入传动轴2正转(顺时针旋转)，在差速器处于空档状态下：换档齿轮1整体布置在空齿轴体段34上方为既不与左倒退档切换齿轮32齿合连接，也不与右倒退档切换齿轮33齿合连接为空档；入前进档时，外部的入档机构通过手动或脚踏形式拉动动力输入旋转轴61逆时针旋转，旋转摆动横杆611通过换档架拨动杆612拨动滑动换档架62沿滑动换档架穿接杆64向右滑行，拉动滑动换档架62同步拨动换档齿轮1沿换档齿轮运动段211向右滑行，使前进档换档齿轮13与右边齿轮413齿合，混合动力输入传动轴2处于正转状态，所以换档齿轮1的前进档换档齿轮13也处于正转状态，由于前进档换档齿轮13是与右边齿轮413齿合连接，所以进退档切换共享齿轮轴41的左边齿轮412及右边齿轮413会变为反转状态(由于倒退档切换齿轮组件3的右倒 退档切换齿轮33是与右边齿轮413齿合的连接，所以倒退档切换齿轮组件3整体处于空转状态)，由于左边齿轮412是与动力输出传动齿轮5齿合连接，所以动力输出传动齿轮5又变为正转状态，所以输出的动力为正转，车轮正转向前行驶。
倒退档的换档过程：
变频电机及发动机传动机构工作时都是驱动混合动力输入传动轴2正转(顺时针旋转)，在差速器处于空档状态下：换档齿轮1整体布置在空齿轴体段34上方为既不与左倒退档切换齿轮32齿合连接，也不与右倒退档切换齿轮33齿合连接为空档；入倒退档时，外部的入档机构通过手动或脚踏形式拉动动力输入旋转轴61顺时针旋转，旋转摆动横杆611通过换档架拨动杆612拨动滑动换档架62沿滑动换档架穿接杆64向左滑行，拉动滑动换档架62同步拨动换档齿轮1沿换档齿轮运动段211向左滑行，使倒退档换档齿轮11与左倒退档切换齿轮32齿合，混合动力输入传动轴2处于正转状态，所以换档齿轮1的前进档换档齿轮13也处于正转状态，而倒退档切换齿轮组件3整体会变为逆转状态，由于右倒退档切换齿轮33是与右边齿轮413齿合的连接，所以进退档切换共享齿轮轴41的左边齿轮412及右边齿轮413会变为正转状态，由于左边齿轮412是与动力输出传动齿轮5齿合连接，所以动力输出传动齿轮5又变为逆转状态，所以输的动力为逆转，车轮逆转倒退行驶。
混合动力输入传动轴、传动轴穿接通孔结构替代方案：
所述传动轴穿接通孔结构不限于前述的定向滑动槽、凸条结构，本技术方案只能作为较佳的技术方案说明；替代方案例如1：传动轴穿接通孔为方形(正方形或长方形)，对应的油电混合动力输入传动轴的换档齿轮运动段也为方形，方形传动轴穿接通孔的换档齿轮穿入油电混合动力输入传动轴的方形换档齿轮运动段也可以实现换档齿轮沿混合动力输入传动轴轴向运动；替代方案例如2：传动轴穿接通孔为 菱形，对应的油电混合动力输入传动轴的换档齿轮运动段也为菱形，菱形传动轴穿接通孔的换档齿轮穿入油电混合动力输入传动轴的菱形换档齿轮运动段也可以实现换档齿轮沿混合动力输入传动轴轴向运动；替代方案例如3：传动轴穿接通孔为椭圆形，对应的油电混合动力输入传动轴的换档齿轮运动段也为椭圆形，椭圆形传动轴穿接通孔的换档齿轮穿入油电混合动力输入传动轴的椭圆形换档齿轮运动段也可以实现换档齿轮沿混合动力输入传动轴轴向运动；总之，换档齿轮的传动轴穿接通孔的形状要与混合动力输入传动轴的换档齿轮运动段形状相同(除圆形或接近圆形外)，即：工作时，换档齿轮是不能单独沿混合动力输入传动轴周向旋转及径向运动的；必须是混合动力输入传动轴驱动换档齿轮旋转，且换档齿轮可通过换档传动机构调节换档齿轮沿混合动力输入传动轴轴向运动(左右滑动)调节档位，档位包括空档、前进档、倒退档。
进退档切换共享转动齿轮组件结构替代方案：
所述进退档切换共享齿轮轴、左边齿轮、右边齿轮可以一体成型，也可以是各自单独部件固定在一起；左边齿轮、右边齿轮并非一定为两个齿轮，也可以用一个齿轮代替，利用齿轮体齿不同角度的侧面分别与前进档换档齿轮、右倒退档切换齿轮、动力输出传动齿轮齿合连接也是可以的。
以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围；在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。
