具体实施方式
下面详细描述本实用新型的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本实用新型，而不能理解为对本实用新型的限制。
下面结合图1-图12对根据本实用新型实施例的动力驱动***100进行详细描述，该动力驱动***100适用于诸如混合动力汽车的车辆中，并作为车辆的动力***，为车辆正常行驶提供充足的动力和电能。
根据本实用新型实施例的动力驱动***100主要包括两大部分，其一可为动力源，动力源可以是发动机4、电动发电机等，其二可为变速器(包括多个输入轴、多个输出轴、挡位齿轮副等)，变速器用于实现对动力源输出动力的变速功能，满足车辆行驶要求或充电要求等。
例如，在一些实施例中，如图1-图12所示，动力驱动***100可以包括发动机4、第一电动发电机51、变速器和差速器，发动机4和第一电动发电机51通过变速器动力耦合连接，然后通过差速器向车轮输出动力以驱动车辆运动，但不限于此。
变速器具有用于输出动力的变速器动力输出部，差速器具有差速器动力输入部和两个差速器动力输出部，差速器动力输入部与变速器动力输出部联动，其中一个差速器动力输出部与同侧的车轮相连，而且另一个差速器动力输出部与同侧的车轮之间设置有动力接合装置7c。可以理解的是，当动力传递至差速器动力输入部时，差速器动力输入部可以将动力分别传递给两个差速器动力输出部，两个差速器动力输出部中的一个直接传递给车轮，另外一个差速器动力输出部在动力接合装置7c处于接合状态时将动力传递给车轮。其中，差速器动力输入部可以为差速器动力输入齿轮7，变速器动力输出部可以为变速器内的多个输出轴上的输出轴输出齿轮和倒挡轴3的倒挡输出齿轮39，输出轴输出齿轮分别与差速器动力输入部啮合，差速器动力输出部可以为差速器动力输出齿轮71，差速器动力输出齿轮71与差速器动力输入齿轮7啮合。
结合图1-12所示，在一些实施例中，变速器主要包括多个输入轴(例如，第一输入轴11、第二输入轴12)、多个输出轴(例如，第一输出轴21、第二输出轴22)、倒挡轴3、倒挡输出齿轮39和各轴上相关齿轮以及换挡元件(如，同步器)。
在发动机4与输入轴之间进行动力传递时，发动机4设置成可选择性地接合多个输入轴中的至少一个。换言之，例如，在发动机4向输入轴传输动力时，发动机4能够选择性地与多个输入轴中的一个接合以传输动力，或者发动机4还能够选择性地与多个输入轴中的两个或两个以上输入轴同时接合以传输动力。
例如，在图1-图12的示例中，多个输入轴可以包括第一输入轴11和第二输入轴12两根输入轴，发动机4能够选择性地与第一输入轴11和第二输入轴12之一接合以传输动力。或者，特别地，发动机4还能与第一输入轴11和第二输入轴12同时接合以传输动力。当然，应当理解的是，发动机4还可同时与第一输入轴11和第二输入轴12断开。
对于本领域的普通技术人员而言，发动机4与输入轴的接合状态与动力驱动***100的具体工况相关，这将在下面结合具体的实施例进行详述，这里不再详细说明。
输入轴与输出轴之间可以通过挡位齿轮副进行传动。例如，每个输入轴上均设置有挡位主动齿轮，每个输出轴上均设置有挡位从动齿轮，挡位从动齿轮与挡位主动齿轮对应地啮合，从而构成多对速比不同的齿轮副。
在本实用新型的一些实施例中，如图1-图12所示，动力驱动***100可以具有七个前进挡齿轮副，即具有一挡齿轮副、二挡齿轮副、三挡齿轮副、四挡齿轮副、五挡齿轮副、六挡齿轮副和七挡齿轮副，动力驱动***100还具有一个倒挡齿轮副。
其中，动力接合装置7c的类型和布置形式有多种，下面详细描述一下。如图1-图8所示，动力接合装置7c可以设置在左车轮和左侧的差速器动力输出齿轮71之间，如图9-图12所示，动力接合装置7c可以设置在右车轮和右侧的差速器动力输出齿轮71之间。如图1-图4、图9和图10所示，动力接合装置7c可以为离合器，如图5-图8、图11和图12所示，动力接合装置7c为同步器。
其中，电动发电机的布置形式和数量也有多种，例如，如图1所示，动力驱动***100内仅具有第一电动发电机51，如图2所示，动力驱动***100内具有第一电动发电机51和第二电动发电机52。
如图1-图12所示，第一电动发电机51与差速器动力输入部联动。第一电动发电机51和差速器动力输入齿轮7(即差速器动力输入部)之间的联动布置方式有多种，下面结合附图详细描述。
第一电动发电机51与车辆的差速器动力输入齿轮7联动。换言之，第一电动发电机51和车辆的差速器动力输入齿轮7之间可以进行动力传递，当第一电动发电机51作为电动机使用时，第一电动发电机51的动力可以通过差速器动力输入齿轮7传递给车轮以驱动车辆运动，当第一电动发电机51作为发电机使用时，车轮传递的能量可以通过差速器动力输入齿轮7传递给第一电动发电机51以使得第一电动发电机51发电。
例如在图1-图2、图5-图6、图9-图12的实施例中，第一电动发电机51的动力通过变速器输出至差速器动力输入齿轮7，也就是说，在这些实施例中，第一电动发电机51与变速器直接动力耦合连接，同时第一电动发电机51通过变速器与差速器动力输入齿轮7间接联动。
但本实用新型并不限于此，又如在图3-图4、图7-图8的实施例中，第一电动发电机51通过齿轮组与差速器动力输入齿轮7联动，也就是说，在这些实施例中，第一电动发电机51与差速器动力输入齿轮7直接联动(不经过变速器)，同时第一电动发电机51通过差速器动力输入齿轮7与变速器与间接动力耦合连接。
多个输出轴与车辆的差速器动力输入齿轮7联动。其中，每个输出轴上均固定设置有输出齿轮，输出齿轮与差速器动力输入齿轮7啮合，例如，如图1所示，输出轴包括：第一输出轴21和第二输出轴22，第一输出轴21上固定设置有第一输出轴输出齿轮211，第二输出轴22上固定设置有第二输出轴输出齿轮221，第一输出轴输出齿轮211和第二输出轴输出齿轮221分别与车辆的差速器动力输入齿轮7啮合，第一输出轴输出齿轮211、第二输出轴输出齿轮221构成变速器动力输出部。由此，发动机4传递出的动力可以经过第一输出轴21上的第一输出轴输出齿轮211传递给差速器动力输入齿轮7，发动机4传递出的动力还可以经过第二输出轴输出齿轮221传递给差速器动力输入齿轮7，或者发动机4传递出的动力还可以通过上述两个输出轴的输出齿轮传递给差速器动力输入齿轮7。
如图1所示，第一电动发电机51与倒挡轴3联动，倒挡轴3通过倒挡输出齿轮39与第二输出轴22联动，从而第一电动发电机51和差速器动力输入齿轮7之间可以联动。具体地，倒挡轴3上还固定设置有第一电机齿轮33，第一电动发电机51通过第一传动齿轮511和第二传动齿轮512与第一电机齿轮33传动，其中第一传动齿轮511固定在第一电动发电机51的电机轴上，第二传动齿轮512啮合在第一传动齿轮511和第一电机齿轮33之间。
如图3所示，第一电动发电机51设置成直接通过多个齿轮与差速器动力输入齿轮7联动，第一电动发电机51和差速器动力输入齿轮7之间设置有第一传动齿轮511、第二传动齿轮512、第三传动齿轮和第四传动齿轮，第一传动齿轮511固定在第一电动发电机51的电机轴上，第二传动齿轮512啮合在第一传动齿轮511和第三传动齿轮之间，其中第三传动齿轮和第四传动齿轮同轴固定布置，第四传动齿轮与差速器动力输入齿轮7啮合。
下面结合图2详细描述第二电动发电机52的布置形式，如图2所示，第二电动发电机52设置成与发动机4联动。当第二电动发电机52作为电动机使用时，第二电动发电机52可以用于启动发动机4，或者第二电动发电机52可以用于驱动车轮转动。当第二电动发电机52作为发电机使用时，发动机4可以驱动第二电动发电机52发电，从车辆传递出的能量可以通过输出轴驱动第二电动发电机52发电。
如图1-图12所示，动力驱动***100还可以包括：双离合器2d，双离合器2d具有输入端23d、第一输出端21d和第二输出端22d，输入端23d可选择性地接合第一输出端21d和第二输出端22d的至少一个，发动机4与输入端23d相连。其中第一输出端21d与第一输出轴21相连，第二输出端22d与第二输出轴22相连。其中，输入端23d上设置有输入端23d外齿，第二电动发电机52与输入端23d外齿联动。由于输入端23d与发动机4相连，这样第二电动发电机52和发动机4之间可以通过输入端23d联动。第二电动发电机52的电机轴上可以固定设置有一个与输入端23d外齿相连的传动齿轮。
应当理解，双离合器2d的具体接合状态受到控制策略的影响，对于本领域的技术人员而言，可以根据实际所需的传动模式而适应性设定控制策略，从而可以在输入端23d与两个输出端全部断开以及输入端23d与两个输出端至少之一接合的多种模式中进行切换。
对于倒挡轴3和倒挡输出齿轮39主要有以下两种布置形式，如图1-图2所示，倒挡轴3上空套设置有能够接合倒挡轴3的倒挡轴第一齿轮31，换言之，倒挡轴3和倒挡轴第一齿轮31之间可以传动，如图1-图2所示，倒挡轴3上还可以设置有倒挡轴第一同步器3c，倒挡轴第一同步器3c用于接合倒挡轴3与倒挡轴第一齿轮31。当倒挡轴第一同步器3c用于接合倒挡轴3和倒挡轴第一齿轮31时，倒挡轴3和倒挡轴第一齿轮31之间传动，倒挡输出齿轮39与倒挡轴3联动，如图1-图2所示，倒挡轴3上可以固定设置有倒挡轴第二齿轮32，倒挡轴第二齿轮32与倒挡输出齿轮39啮合。倒挡输出齿轮39可以固定在其中一个输出轴上。如图1-图2所示，倒挡输出齿轮39固定在第二输出轴22上，这样可以使得倒挡输出齿轮39布置位置合理，可以进一步地降低动力驱动***100的体积。
如图3-图4所示，倒挡轴第一齿轮31还可以固定设置在倒挡轴3上，此时，倒挡输出齿轮39可以空套设置在输出轴中的一个(例如第二输出轴22)上，并且倒挡输出齿轮39设置成可接合该输出轴。具体地，该输出轴上还设置有用于接合倒挡输出齿轮39的倒挡同步器(例如六挡同步器6c)，换言之，倒挡同步器同步对应的倒挡输出齿轮39和该输出轴，从而使得输出轴与倒挡输出齿轮39能够同步转动，进而倒挡动力能够从该输出轴输出。优选地，如图3-图4所示，倒挡输出齿轮39与相邻的一个挡位从动齿轮(例如六挡从动齿轮6b)共用倒挡同步器。由此，可以减少动力驱动***100的零部件，可以使得动力驱动***100轴向长度较小，可以降低动力驱动***100的体积。
倒挡轴第一齿轮31与其中一个挡位主动齿轮啮合，例如，如图1所示，倒挡轴第一齿轮31与一挡主动齿轮1a啮合，这样倒挡轴第一齿轮31与一挡主动齿轮1a共同构成倒挡齿轮副，倒挡轴3和输入轴之间可以动力传递。
如图1-图12所示，第二输入轴12套设在第一输入轴11上，这样可以使得动力驱动***100结构紧凑，而且可以有效减小动力驱动***100的轴向长度，可以使得动力驱动***100的体积较小，可以便于动力驱动***100在车辆上的布置。
下面结合图1-图8详述一种变速器的各齿轮副布置形式。
如图1-图8所示，第一输入轴11上可以布置有一挡主动齿轮1a、三五挡主动齿轮35a和七挡主动齿轮7a，第二输入轴12上可以布置有二挡主动齿轮2a和四六挡主动齿轮46a，每个挡位主动齿轮均随对应的输入轴同步转动。
对应地，如图1-图8所示，第一输出轴21上设置有一挡从动齿轮1b、二挡从动齿轮2b、三挡从动齿轮3b和四挡从动齿轮4b，第二输出轴22上设置有五挡从动齿轮5b、六挡从动齿轮6b和七挡从动齿轮7b，每个挡位从动齿轮均空套在对应的输出轴上，即每个挡位从动齿轮相对于对应的输出轴能够差速转动。
其中，一挡从动齿轮1b与一挡主动齿轮1a啮合从而构成一挡齿轮副，二挡从动齿轮2b与二挡主动齿轮2a啮合从而构成二挡齿轮副，三挡从动齿轮3b与三五挡主动齿轮35a啮合从而构成三挡齿轮副，四挡从动齿轮4b与四六挡主动齿轮46a啮合从而构成四挡齿轮副，五挡从动齿轮5b与三五挡主动齿轮35a啮合从而构成五挡齿轮副，六挡从动齿轮6b与四六挡主动齿轮46a啮合从而构成六挡齿轮副、七挡从动齿轮7b与七挡主动齿轮7a啮合从而构成七挡齿轮副，一挡从动齿轮1b与倒挡轴第一齿轮31啮合从而构成倒挡齿轮副。
其中四挡齿轮副和六挡齿轮副共用四六挡主动齿轮46a，三挡齿轮副和五挡齿轮副共用三五挡主动齿轮35a，从而可以减少两个挡位主动齿轮，使得动力驱动***100的结构更加紧凑，轴向尺寸更小。
由于从动齿轮与输出轴之间为空套结构，因此需要设置同步器对相应的从动齿轮与输出轴进行同步，以实现动力的输出。
在一些实施例中，结合图1-图8所示，动力驱动***100包括一三挡同步器13c、二四挡同步器24c、五七挡同步器57c和六挡同步器6c。
如图1所示，一三挡同步器13c设置在第一输出轴21上且位于一挡从动齿轮1b与三挡从动齿轮3b之间，一三挡同步器13c可将一挡从动齿轮1b或三挡从动齿轮3b与第一输出轴21进行接合，从而使该从动齿轮与输出轴能够同步转动。
例如，结合图1所示，一三挡同步器13c的接合套向左移动可将三挡从动齿轮3b与第一输出轴21接合，从而三挡从动齿轮3b与第一输出轴21能够同步转动。一三挡同步器13c的接合套向右移动可将一挡从动齿轮1b与第一输出轴21接合，从而一挡从动齿轮1b与第一输出轴21能够同步转动。
如图1所示，类似地，二四挡同步器24c设置在第一输出轴21上且位于二挡从动齿轮2b与四挡从动齿轮4b之间，二四挡同步器24c可将二挡从动齿轮2b或四挡从动齿轮4b与第一输出轴21进行接合，从而使该从动齿轮与输出轴能够同步转动。
例如，结合图1所示，二四挡同步器24c的接合套向左移动可将二挡从动齿轮2b与第一输出轴21接合，从而二挡从动齿轮2b与第一输出轴21同步转动。二四挡同步器24c的接合套向右移动可将四挡从动齿轮4b与第一输出轴21接合，从而四挡从动齿轮4b与第一输出轴21同步转动。
如图1所示，类似地，五七挡同步器57c设置在第二输出轴22上，五七挡同步器57c位于五挡从动齿轮5b和七挡从动齿轮7b之间，五七挡同步器57c用于将五挡从动齿轮5b或七挡从动齿轮7b与第二输出轴22接合，例如五七挡同步器57c的接合套向右移动，则可将七挡从动齿轮7b与第二输出轴22接合，从而七挡从动齿轮7b与第二输出轴22同步转动。又如，五七挡同步器57c的接合套向左移动，则可将五挡从动齿轮5b与第二输出轴22接合，从而五挡从动齿轮5b与第二输出轴22同步转动。
如图1所示，类似地，六挡同步器6c设置在第二输出轴22上，六挡同步器6c位于六挡从动齿轮6b的一侧，例如左侧，六挡同步器6c用于将六挡从动齿轮6b与第二输出轴22接合，例如六挡同步器6c的接合套向右移动，则可将六挡从动齿轮6b与第二输出轴22接合，从而六挡从动齿轮6b与第二输出轴22同步转动。
如图3、图4、图7-图8所示，倒挡输出齿轮39与六挡从动齿轮6b相邻设置以共用六挡同步器6c，从而六挡同步器6c构成倒挡同步器。结合图3、图4、图7-图8所示，六挡同步器6c的接合套向左移动可接合倒挡输出齿轮39、而向右移动可接合六挡从动齿轮6b。
在一些实施例中，如图1所示，二挡主动齿轮2a、四六挡主动齿轮46a、三五挡主动齿轮35a、一挡主动齿轮1a、七挡主动齿轮7a与发动机4的距离递增。由此，挡位布置更加合理，动力驱动***100更加紧凑，径向及轴向尺寸相对更小。
对于倒挡输出齿轮39固定设置在第二输出轴22上的动力驱动***100，倒挡轴第一齿轮31空套在倒挡轴3上，而且倒挡轴3上设置有用于接合倒挡轴第一齿轮31的倒挡轴第一同步器3c，其中六挡同步器6c位于六挡从齿轮的左侧，倒挡轴第一同步器3c位于倒挡轴第一齿轮31的右侧，这样倒挡轴第一同步器3c与六挡同步器6c可以共用同一拨叉机构，在拨叉机构驱动倒挡轴第一同步器3c接合倒挡轴第一齿轮31时、六挡同步器6c与六挡从动齿轮6b分离，在拨叉机构驱动六挡同步器6c接合六挡从动齿轮6b时、倒挡轴第一同步器3c与倒挡轴第一齿轮31分离。具体地，当拨叉机构带动接合套向左移动时，倒挡轴第一同步器3c接合倒挡轴第一齿轮31且六挡同步器6c与六挡从动齿轮6b分离，当拨叉机构带动接合套向右移动时，六挡同步器6c接合六挡从动齿轮6b且倒挡轴第一同步器3c与倒挡轴第一齿轮31分离。由此，动力驱动***100可以省去一个拨叉机构，从而可以使得动力驱动***100结构简单，重量轻。
下面结合图9-图12详述另一种变速器的各齿轮副布置形式.
如图9-图12所示，第一输入轴11上可以布置有一挡主动齿轮1a、三挡主动齿轮3a、五挡主动齿轮5a和七挡主动齿轮7a，第二输入轴12上可以布置有二挡主动齿轮2a和四六挡主动齿轮46a，每个挡位主动齿轮均随对应的输入轴同步转动。

其中，一挡从动齿轮1b与一挡主动齿轮1a啮合从而构成一挡齿轮副，二挡从动齿轮2b与二挡主动齿轮2a啮合从而构成二挡齿轮副，三挡从动齿轮3b与三挡主动齿轮3a啮合从而构成三挡齿轮副，四挡从动齿轮4b与四六挡主动齿轮46a啮合从而构成四挡齿轮副，五挡从动齿轮5b与五挡主动齿轮5a啮合从而构成五挡齿轮副，六挡从动齿轮6b与四六挡主动齿轮46a啮合从而构成六挡齿轮副、七挡从动齿轮7b与七挡主动齿轮7a啮合从而构成七挡齿轮副，一挡从动齿轮1b与倒挡轴第一齿轮31啮合从而构成倒挡齿轮副。
其中四挡齿轮副和六挡齿轮副共用四六挡主动齿轮46a，从而可以减少一个挡位主动齿轮，使得动力驱动***100的结构更加紧凑，轴向尺寸更小。
由于从动齿轮与输出轴之间为空套结构，因此需要设置同步器对相应的从动齿轮与输出轴进行同步，以实现动力的输出。
在一些实施例中，结合图9-图12所示，动力驱动***100包括一三挡同步器13c、二四挡同步器24c、五七挡同步器57c和六挡同步器6c。
如图9所示，一三挡同步器13c设置在第一输出轴21上且位于一挡从动齿轮1b与三挡从动齿轮3b之间，一三挡同步器13c可将一挡从动齿轮1b或三挡从动齿轮3b与第一输出轴21进行接合，从而使该从动齿轮与输出轴能够同步转动。
例如，结合图9所示，一三挡同步器13c的接合套向左移动可将三挡从动齿轮3b与第一输出轴21接合，从而三挡从动齿轮3b与第一输出轴21能够同步转动。一三挡同步器13c的接合套向右移动可将一挡从动齿轮1b与第一输出轴21接合，从而一挡从动齿轮1b与第一输出轴21能够同步转动。

如图9所示，类似地，五七挡同步器57c设置在第二输出轴22上，五七挡同步器57c位于五挡从动齿轮5b和七挡从动齿轮7b之间，五七挡同步器57c用于将五挡从动齿轮5b或七挡从动齿轮7b与第二输出轴22接合，例如五七挡同步器57c的接合套向右移动，则可将七挡从动齿轮7b与第二输出轴22接合，从而七挡从动齿轮7b与第二输出轴22同步转动。又如，五七挡同步器57c的接合套向左移动，则可将五挡从动齿轮5b与第二输出轴22接合，从而五挡从动齿轮5b与第二输出轴22同步转动。
如图9所示，类似地，六挡同步器6c设置在第二输出轴22上，六挡同步器6c位于六挡从动齿轮6b的一侧，例如左侧，六挡同步器6c用于将六挡从动齿轮6b与第二输出轴22接合，例如六挡同步器6c的接合套向右移动，则可将六挡从动齿轮6b与第二输出轴22接合，从而六挡从动齿轮6b与第二输出轴22同步转动。
在一些实施例中，如图9所示，二挡主动齿轮2a、四六挡主动齿轮46a、三挡主动齿轮3a、五挡主动齿轮5a、一挡主动齿轮1a、七挡主动齿轮7a与发动机4的距离递增。由此，挡位布置更加合理，动力驱动***100更加紧凑，径向及轴向尺寸相对更小。
倒挡轴第一齿轮31空套在倒挡轴3上，而且倒挡轴3上设置有用于接合倒挡轴第一齿轮31的倒挡轴第一同步器3c，其中六挡同步器6c位于六挡从齿轮的左侧，倒挡轴第一同步器3c位于倒挡轴第一齿轮31的右侧，这样倒挡轴第一同步器3c与六挡同步器6c可以共用同一拨叉机构，在拨叉机构驱动倒挡轴第一同步器3c接合倒挡轴第一齿轮31时、六挡同步器6c与六挡从动齿轮6b分离，在拨叉机构驱动六挡同步器6c接合六挡从动齿轮6b时、倒挡轴第一同步器3c与倒挡轴第一齿轮31分离。具体地，当拨叉机构带动接合套向左移动时，倒挡轴第一同步器3c接合倒挡轴第一齿轮31且六挡同步器6c与六挡从动齿轮6b分离，当拨叉机构带动接合套向右移动时，六挡同步器6c接合六挡从动齿轮6b且倒挡轴第一同步器3c与倒挡轴第一齿轮31分离。由此，动力驱动***100可以省去一个拨叉机构，从而可以使得动力驱动***100结构简单，重量轻。

具体地，如图9-图12所示，倒挡轴3上还固定设置有第一电机齿轮33，第一电动发电机51通过第一传动齿轮511和第二传动齿轮512与第一电机齿轮33传动，其中第一传动齿轮511固定在第一电动发电机51的电机轴上，第二传动齿轮512啮合在第一传动齿轮511和第一电机齿轮33之间。
如图9-图12所示，多个输出轴、倒挡轴3分别与差速器动力输入部(即差速器动力输入齿轮7)联动。倒挡轴3上固定设置有倒挡轴输出齿轮38，当倒挡轴第一同步器3c用于接合倒挡轴3和倒挡轴第一齿轮31时，倒挡轴3通过倒挡轴输出齿轮38与差速器动力输入齿轮7传动。这样输出轴输出齿轮和倒挡轴输出齿轮38共同构成变速器动力输出部。
