如前所述，图2-图6是本申请混合动力系统第一实施例发动机1驱动模式不同挡位的动力流示意图，本申请通过多个换挡元件可以实现发动机1驱动模式下一挡至五挡的挡位切换。本申请通过多个换挡元件还可以实现发动机1驱动、电机驱动等模式的自由切换。请参阅图7和图8，图7是本发明混合动力系统第一实施例第一电机驱动模式动力流示意图，图8是本发明混合动力系统第一实施例第二电机驱动模式动力流示意图，如图7所示，第三换挡元件35通过换挡动作将第一行星架312与固定齿座33连接，即将第一行星架312固定，第一换挡元件315通过换挡动作将第一行星架312与第一太阳轮313断开，第一电机的动力通过第一外齿圈311、第一行星轮314将动力传至第一太阳轮313，进而传至第一输入轴41，第一输入轴41再将动力传递至变速箱内的第一输入齿轮411，第一输入齿轮411和第一减速齿轮431啮合，以将第一输入轴41的动力传递到第一中间轴43上，一三挡换挡元件435与三挡空套齿轮432相连，三挡空套齿轮432和三四挡固连齿轮453啮合，以将第一中间轴43的动力传递至第一输出轴45输出。同理，当一三挡换挡元件435与一挡空套齿轮433相连，一挡空套齿轮433和一二挡固连齿轮454啮合，以将第一中间轴43的动力传递至第一输出轴45输出。同理，当五挡换挡元件455将第一输入齿轮411和第一输出轴45连接，第一输入轴41的动力传递至第一输出轴45输出。本申请通过多个换挡元件可以实现第一电机驱动模式下一挡、三挡、五挡的挡位切换。

本申请还通过将发动机1驱动模式和电机驱动模式任意排列组合，可以实现多种混合驱动模式。例如，第一换挡元件315连接，第三换挡元件35断开，第一太阳轮313和第一行星架312共同旋转，此时，发动机1的动力和第一电机的动力在第一太阳轮313处混合，混合后的动力再共同输入至第一输入轴41，同理，可以实现发动机1的动力和第二电机的动力混合模式及发动机1的动力和第一电机、第二电机的动力混合模式，上述设计，使得发动机1能够与电机混合驱动，具有更好的混动效果。
本申请还通过将电机驱动的动力流改变传递方向，即车辆动力经变速器4的输出轴传递到中间轴，经行星减速机构最终传递到电机内发电，实现再生制动。
在一些实施例中，如图1所示，一三挡换挡元件435、二四挡换挡元件445、五挡换挡元件455均采用滑动齿套结构，三挡空套齿轮432与四挡空套齿轮442结构和尺寸均相同，一挡空套齿轮433与二挡空套齿轮443结构和尺寸均相同。
可以理解的是，将变速器4的多个换挡元件分别采用相同零部件，可以减少零部件品种，降低生产成本，变速器4的两个中间轴上，一挡空套齿轮433与二挡空套齿轮443采用相同零部件，三挡空套齿轮432与四挡空套齿轮442采用相同零部件，尺寸和结构一致的空套齿轮均与同一固连齿轮相啮合，即可实现多挡位速比，可降低变速器4内齿轮副的总数量，缩短混合动力系统的轴向长度，降低重量和成本。
在一些实施例中，第一电机和第二电机为油冷电机，以降低电机重量、满足电机轻量化的需求。
在一些实施例中，如图1所示，混合动力系统还包括减震器2，减震器2设置于发动机1和功率分流系统3之间，以将发动机1输出扭矩减震，进而防止扭矩冲击或波动带来的传动系统可靠性问题或驾驶舒适性问题。
在另一些实施例中，如图9所示，图9是本发明混合动力系统第二实施例的结构示意图，本实施例的混合动力系统包括发动机1、减震器2、功率分流系统3、变速器4，与第一实施例不同的是，本实施例还包括第一副箱5，可进一步减速增扭，提升整车重载适应能力，具体地，第一副箱5包括第一副箱太阳轮51、第一副箱外齿圈52、第一副箱行星架53、第一副箱行星轮54、第一副箱换挡机构55、第二输出轴64，第一副箱太阳轮51与第一输出轴45相连，第一副箱行星轮54分别与第一副箱太阳轮51和第一副箱外齿圈52啮合连接，第一副箱行星轮54转动连接于第一副箱行星架53，第一副箱5换挡元件可滑动地设置于第一副箱外齿圈52和第一副箱行星架53之间，以使第二输出轴64借助于第一副箱换挡机构55择一地与第一副箱外齿圈52和第一副箱行星架53中的其中之一连接。
可以理解的是，第一副箱行星架53为第一副箱5的动力输出端，当第一副箱5在低速挡工作时，第一副箱换挡机构55将第一副箱外齿圈52固定，第一副箱太阳轮51的动力经第一副箱行星轮54减速增扭从第一副箱行星架53输出。当第一副箱5在高速挡工作时，第一副箱换挡机构55将第一副箱外齿圈52与第一副箱行星架53相连，第一副箱太阳轮51带动第一副箱行星轮54整体转动输出。
在另一些实施例中，如图10所示，图10是本发明混合动力系统第三实施例的结构示意图，本实施例的混合动力系统包括发动机1、减震器2、功率分流系统3、变速器4，与第一实施例不同的是，本实施例还包括第二副箱6，可进一步减速增扭，提升整车重载适应能力，具体地，第二副箱6包括第三输入齿轮61、第三中间轴62、第四中间轴63、第二输出轴64，第一输入轴41上固设有第三输入齿轮61，第三中间轴62上依次设置有第三减速齿轮621、第一固连齿轮622，第四中间轴63上依次设置有第四减速齿轮631、第二固连齿轮632，第二输出轴64上依次设置有第二副箱换挡机构642、第二副箱空套齿轮641，第二副箱空套齿轮641相对于第二输出轴64空转，第三减速齿轮621和第四减速齿轮631均与第三输入齿轮61啮合连接，第一固连齿轮622和第二固连齿轮632均与第二副箱空套齿轮641啮合连接，第二副箱换挡机构642可滑动地设置于第三输入齿轮61与第二副箱空套齿轮641之间，以使第二输出轴64借助于第二副箱空套齿轮641择一地与第三输入齿轮61和第二副箱空套齿轮641中的其中之一连接。
可以理解的是，当第二副箱6在低速挡工作时，第二副箱换挡机构642换到低挡位置，第二副箱空套齿轮641与第二输出轴64相连，第三输入齿轮61动力经第三中间轴62上的第三减速齿轮621、第四中间轴63上的第四减速齿轮631分别和第一固连齿轮622、第二固连齿轮632啮合，最后从第二副箱空套齿轮641减速增扭输出。当第二副箱6在高速挡工作时，第二副箱换挡机构642将第三输入齿轮61与第二输出轴64相连，第三输入齿轮61带动第二输出轴64整体转动输出。
本发明的混合动力系统，通过采用双电机功率分流系统3调整挡位，两个输入轴与对应的中间轴减速比不同，实现不同速比，变速器4的两个中间轴分别集成一个高速电机加行星减速机构，实现与发动机1并联、串联动力耦合，同时，降低了电机的扭矩需求，实现了电机的低成本、轻量化。
本发明的混合动力系统，齿轮的传动比可根据整车工况和发动机1、电机特性进行匹配和设置，由于发动机1可使用全部挡位，单个电机可使用部分挡位，从而得到一种可以使发动机1和电机并联、串联动力耦合，实现发动机1和电机全工况下工作在高效区间的混合动力系统，提升了整车燃油经济性。
本发明的混合动力系统，具有电机驱动、发动机1驱动、混合驱动、再生制动等多种重要混动功能模式。商用车在实际运行中，一般为空载、满载等多种行驶质量状态，高速、低速等多种行驶速度状态，例如，某车辆空载时与满载时，质量相差很大，低速工况和高速工况对动力的需求差异很大。应用本发明的混合动力系统，当重载起步或爬坡、需求大扭矩，或中高速巡航、需求大功率时，采用双电机或发动机1电机并联驱动模式，中低速平路行驶、扭矩和功率需求不大时，采用纯电机驱动模式，本发明不同功能模式可以满足多种工况策略下的整车行驶需要，进一步提升了整车燃油经济性。而且，匹配双电机使系统具备串联驱动功能，使某一电机驱动车辆起步及低速或中速行驶，发动机1驱动另一电机发电给蓄电装置充电或者给驱动电机供电，可以满足车辆在市区或其他低速工况下长期行驶的需求。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
