所述离合器120可以是干式离合器120也可以为湿式离合器120，所述离合器120用于结合或者分离第一输入轴160与第二电机140的电机轴，由上述内容可知，本申请的第二电机140位于第一输入轴160远离发动机110的一端，因此离合器120也设置在第一输入轴160远离发动机110的一端，其中离合器120的离合毂固定在第二电机140的电机轴上。
所述同步器210包括第一同步器211和第二同步器212，所述第一同步器211用于选 择性连接第二电机140的电机轴和第二输入轴170，第二同步器212用于选择性连接所述第一齿轮副220中的第一从动齿轮222和输出轴180。
本申请在发动机110的飞轮输出端处设置行星齿轮机构150，并将第一电机130与行星齿轮机构150传动连接于行星齿轮机构150的齿圈154，由此第一电机130的设置方式构成P1结构，第二电机140连接在第一输入轴160的末端并能直接驱动输出轴180，由此第二电机140的设置方式构成P3结构，第一齿轮副220和第二齿轮副230在第一输入轴160上间隔排布并位于第一电机130和第二电机140之间，由此本申请的多档位混合动力变速器采用P1+P3结构，并且通过第一同步器211选择性连接第二电机140的电机轴和第二输入轴170，以及第二同步器212选择性连接第一齿轮副220中的第一从动齿轮222和输出轴180，使得第二电机140和发动机110的档位可以互相利用，从而在极短的轴向空间内，利用第一齿轮副220、第二齿轮副230、行星齿轮机构150、离合器120、制动器190的组合，使得发动机110有3个档位，第二电机140按照需要实现1档和按需组合3个档位，可实现串联驾驶(第二电机140电机驱动，第一电机130发电)，可实现并联驾驶(发动机110和第二电机140并联驾驶)，同时通过以上设置，可以降低第二电机140的工作转速，第二电机140损失小，档位传递链短效率高，且变速器结构简单，空间布置紧凑，离合器120和制动器190在换挡过程可以滑摩控制，可以实现动力换挡，模式切换和档位切换均可以实现无动力中断，兼顾低中高车速和各种负载情况下的高效率输出以及良好的驾驶感觉。
进一步地，本实施例中，多档位混合动力变速器还包括电池包(未示出)，其中第一电机130和电池包连接，第二电机140也和电池包连接，第一齿轮副220为形成一档的低档齿轮副，而第二齿轮副230则为形成二档三档共用齿轮副，本申请的多档位混合动力变速器具有多种驱动模式，其中，主要工作模式如下表所示：

Figure PCTCN2021107470-appb-000002
也即：
纯电1档模式时，第二电机140通过电池包供电，第二电机140的电机轴通过第一齿轮副220向输出轴180方向传递动力，此时发动机110未启动，通过第二同步器212结合第一齿轮副220的第一从动齿轮222和输出轴180，实现以单独第二电机140进行驱动的纯电1档运行模式。
纯电3档模式时，发动机110未启动，第二电机140通过电池包供电，此时第一同步器211结合第二电机140的电机轴和第二输入轴170，则第二电机140的动力通过第二输入轴170、第二齿轮副230向输出轴180传递，从而实现纯电3档驱动模式。
串联1档模式时，发动机110启动并通过行星齿轮机构150驱动第一电机130发电而为第二电机140进行供电，此时离合器120未结合第一输入轴160和第二电机140的电机轴，第二电机140以再以纯电1档的动力传递路径实现向车轮的动力输出。
串联3档模式时，发动机110启动并通过行星齿轮机构150驱动第一电机130发电而为第二电机140进行供电，此时离合器120未结合第一输入轴160和第二电机140的电机轴，第二电机140以再以纯电3档的动力传递路径实现向车轮的动力输出。
并联1档模式时，发动机110启动，此时离合器120结合第一输入轴160和第二电机140的电机轴，并且第二同步器212连接第一齿轮副220中的第一从动齿轮222和输出轴180，如此实现发动机110和第二电机140同时实现一档的并联输出。
并联2档模式时，发动机110启动，此时离合器120结合第一输入轴160和第二电机140的电机轴，第一同步器211和第二同步器212均处于分离状态，而此时制动器190启动而锁止行星齿轮机构150的太阳轮151，则发动机110和第二电机140的动力将均通过第二齿轮副230实现向输出轴180方向传递，进而实现并联2档模式的动力输出。
并联3档模式时，发动机110启动，此时离合器120结合第一输入轴160和第二电机140的电机轴，制动器190未启动，第二同步器212处于分离状态，第一同步器211结合第二电机140的电机轴和第二输入轴170，则发动机110的动力以及第二电机140的动力均可以通过第二齿轮副230实现向的输出轴180方向传递，实现并联3档驱动模式。
请参照图3，图3为本申请多档位混合动力变速器的第二实施例，第二实施与第一实施例的区别在于第二齿轮副230中的第二主动齿轮231已经变为空套于第二输入轴170，并且同步器210设置为3个，分别为第一同步器211、第二同步器212以及第三同步器210，第一同步器211用于选择性连接第二电机140的电机轴和第二输入轴170，第二同步器212用于选择性连接第一齿轮副220中的第一从动齿轮222和输出轴180，第三同步器210用于选择性连接第二主动齿轮231和第二输入轴170，本实施例的方案，具备第一实施例的优点的情况下，还增加一个档位，使得车辆实际使用过程中，更能符合不同路况的驾驶需求。
请参照图4，图4为本申请多档位混合动力变速器的第三实施例，第三实施例相较于第一实施例而言，进行了以下结构调整，其中，第一齿轮副220中的第一主动齿轮221为空套在第二电机140的电机轴上，第一齿轮副220中的第一从动齿轮222为固套在输出轴180上，并且将同步器210由第一实施例的两个变成一个，该单独一个同步器210可以实现选择性连接第二电机140的电机轴和第一主动齿轮221以及选择性连接第二电机140的电机轴和第二输入轴170两个功能，本实施例可以使得整个多档位混合动力变速器的结构更为简化。
请参照图5，图5为本申请多档位混合动力变速器的第四实施例，第四实施例相较于第一实施例而言，取消了第一同步器211和第二同步器212，第一齿轮副220中的第一从动齿轮222固套于输出轴180，并且离合器120为两个，包括第一离合器121和第二离合器122，第一离合器121用于结合或者分离第一输入轴160与第二电机140的电机轴，第二离合器122用于结合或分离齿圈154和行星架153。本实施例通过增加第二离合器122，则当要挂3档的时候，将第二离合器122结合，则行星齿轮机构150的齿圈154和行星架153同速，此时行星机构的速比为1。这样整体结构也具有较为紧凑的优点。
请参照图6和图7，图6和图7为本申请多档位混合动力变速器的第五实施例，在第五实施例中，多档位混合动力变速器包括发动机110、离合器120、第一电机130、第二电机140、行星齿轮机构150、第一输入轴160、输出轴180、制动器190以及不同速比的第一齿轮副220和第二齿轮副230。

请参照图8和图9，图8和图9为本申请多档位混合动力变速器的第六实施例，在第六实施例中，多档位混合动力变速器包括发动机110、离合器120、第一电机130、第二电机140、行星齿轮机构150、第一输入轴160、输出轴180、制动器190以及不同速比的第一齿轮副220和第二齿轮副230。
所述行星齿轮机构150包括太阳轮151、行星轮组152、齿圈154以及行星架153，所述太阳轮151与所述第一输入轴160同轴设置，所述发动机110的飞轮输出端与所述齿圈154连接，所述第一电机130的转子与所述齿圈154传动连接，所述制动器190与所述太阳轮151连接。

本申请在以上任意中，所述多档位混合动力变速器还包括差速器240，所述差速器240安装有差速器齿圈241，所述输出轴180上安装有主减速齿轮250，所述主减速齿轮250与所述差速器齿圈241常啮合，其中，所述主减速齿轮250在所述输出轴180上位于所述第一齿轮副220和所述第二齿轮副230之间的位置，或者所述主减速齿轮250在所述输出轴180上位于所述第一齿轮副220背离所述第二齿轮副230的一侧位置，或者所述主减速齿轮250在所述输出轴180上位于所述第二齿轮副230背离所述第一齿轮副220的一侧位置，也即主减速齿轮250在输出轴180上的位置可以根据需要进行调整，如此使得本申请的多档位混合动力变速器更容易进行结构设置，使得其整体结构具有紧凑的优点。
