Description

安装有涡轮的P2前轮驱动变速器结构
技术领域
本公开涉及机动车辆动力传动***，其包括被称为P2混合动力变速器的发动机-电动机联合变速器组件。
背景技术
根据本公开的混合动力机动车辆包括小汽车、运动型多用途车、货车、轻型卡车包括小型敞篷货车等，通常设置有与变速器耦接的汽油或柴油动力发动机，且电动机与电池源相连并由其供电，该电池源为汽车提供了备用的驱动装置。电动机在电池提供能量时运转，以提高行驶经济性，而发动机在需要最大功率时运行，例如在高速公路车辆运行期间，以及在用于运转电动机的电池功率不足时。
用于在混合动力电动车辆中连接电动机的各种动力总成架构包括P0、P1、P2、P3和P4设计。P0架构通过前端附件驱动器上的皮带将电动机与内燃机相连。P1架构的电动机直接与发动机的曲轴连接。P2体系结构设置有电动机，可通过使用皮带实现侧面连接，也可以集成在发动机和变速器之间，电动机与发动机分离。P3架构设有通过齿轮啮合固定在变速器上的电动机，电动机的速度是车轮速度的倍数。P4架构设有通过齿轮啮合安装在后轴驱动器或轮毂上的电动机。变矩器连同包括P2混合动力变速器的自动变速器一起使用以改善车辆的发动和换挡是有优势的。变矩器通常会使变速器组件的长度增加100mm以上，从而在机动车辆的发动机舱内引入了组装限制。
由于发动机舱的这些组装限制，已知的P2混合动力变速器的电动机通常位于发动机和变速器之间的钟形壳体内。此电动机位置延长了发动机-变速器组件的总体长度，并且通常需要去除变矩器以适应布置限制。变矩器由滑动离合器代替，以启动车辆。与具有变矩器的动力传动***相比，在带滑动离合器的前轮驱动(FWD)车辆中使用的已知P2混合动力变速器和发动机组件可能会出现变速不佳的情况。
因此，在实现当前的P2混合动力变速器和发动机组件的预期目的的同时，需要一种新的和改进的包括变矩器和电动机的P2混合动力变速器和发动机组件。

根据本文提供的描述，其他应用领域将变得显而易见。应该理解的是，描述和具体示例仅旨在用于说明的目的，并不旨在限制本公开的范围。
附图说明
本文描述的附图仅用于说明目的，并且不旨在以任何方式限制本公开的范围。
图1是根据一个示例性方面的P2变速器和发动机组件的一部分的横截面正视图；以及
图2是由图1的P2变速器和发动机组件限定的六速变速器的修改的杠杆图。
具体实施方式
以下描述本质上仅是示例性的，并且无意于限制本发明的公开、应用或用途。
参照图1，用于机动车辆的前轮驱动(FWD)横向安装的P2变速器和发动机组件10包括发动机安装或变速器第一端12，以连接到例如汽油机或柴油机之类的内燃机14(大概地示出)。本文所定义的横向安装使发动机14和变速器16对准，变速器16具有一条中心线，该中心线定向成横向对准汽车前轮。P2变速器和发动机组件10还包括位于变速器16的第一端12处的变矩器18。变矩器18提供用于将动力从发动机14传递至齿轮组20的液压旋转驱动连接。在图示的示例中包括三个行星齿轮组的齿轮组20具有太阳齿轮、圈齿轮、行星齿轮和正如所知的用于每个行星齿轮组的行星齿轮架。在所示的非限制性示例中，齿轮组20限定了六速齿轮组，该六速齿轮组与变矩器18一起连接至涡轮轴22并由涡轮轴22旋转。在本公开的范围内还可以提供其它多速齿轮组。涡轮轴22相对于旋转轴24旋转，旋转轴24在FWD构造中横向于汽车的中心轴布置。
变速器齿轮箱部26包括变速器第二端28，其相对于变速器第一端12相对地定位。变速器齿轮箱部26还包括定位在变速器齿轮箱部26的第一腔室32内的电动机30，第一腔室32位于变速器第二端28处。位于变速器第二端28处的电动机30因此相对于位于变速器第一端12处的变矩器18相对地定位。电动机30包括转子34和定子36，定子36具有多个绕定子36的周长定位的绕线匝38。电动机30通电时使连接件40旋转，连接件40例如通过花键齿轮与涡轮轴22相连，并且连接件40在变速器齿轮箱部26内相对于旋转轴24旋转。
第一离合器组件42和第二离合器组件44定位在变速器齿轮箱部26的第二腔46中。使用第一穿通轴承50通过第一固定活塞48致动第一离合器组件42。在变速器第二端28处第一固定活塞48受到支撑。使用第二穿通轴承54通过第二固定活塞52致动第二离合器组件44。在变速器第二端28处第二固定活塞52受到支撑。固定活塞与穿通轴承的配合使用淘汰了旋转离合器，从而降低了对变速器操作的液压需求。在变速器齿轮箱部26内还设置第三离合器组件56。还设有第四离合器组件58和第五离合器组件60，与齿轮组20的各个构件接合。
还设有单向离合器62，实现发动机14与变速器16的机械断开，因此允许仅使用电动机30运行。根据多个方面，在变矩器18的壳体或主体内设置单向离合器62。单向离合器62例如通过花键与涡轮轴22相连，并且允许变矩器18与涡轮轴22分离。当单向离合器62分离时，变矩器18与涡轮轴22断开，允许电动机30在不转动发动机14的情形下运转。通过将电动机30并入变速器齿轮箱部26中，P2变速器和发动机组件10在变速器第一端12和变速器第二端28之间提供了一个总长度64，与将电动机定位在钟形壳体内并且省略了变矩器18的P2变速器的传统变型相比，该总长度增加了不到25毫米。
参照图2并且再到图1，根据几个方面，发动机14与变矩器18的定子66相连，并且涡轮轴22与变矩器18的涡轮68相连。根据几个方面，齿轮组20包括第一行星齿轮组70，第二行星齿轮组72和第三行星齿轮组74。变速器输出76与第一行星齿轮组70互连。
P2变速器和发动机组件10的结构为容纳电动机30的第一腔室32提供了最小容积，以优化封装。P2变速器和发动机组件10在支撑电动机30的结构的空间内设置有第一离合器组件42和第二离合器组件44，该电动机30连接到第一固定活塞48和第二活塞52，并且设置了第一穿通轴承50和第二穿通轴承54以减少摩擦损失，同时可以改善封装尺寸。电动机30限定了安装有涡轮机的电动机，该电动机通过第一离合器组件42和第二离合器组件44直接连接至输出76，这不同于需要额外的分离离合器的传统的前置P2发动机和变速器组件。
本公开的P2变速器和发动机组件10提供了多个优势。这些优势包括P2 FWD变速器布置和电动机30位置的提供，这相对于钟形壳体内的传统电动机位置提供了封装优势。定位在变速器16的变速器第二端28处的第一腔室32中的电动机30从与旋转离合器耦合改变成用第一穿通轴承50和第二穿通轴承54耦合到坚实的第一离合器组件42和第二离合器组件44，使得变速器16内没有旋转离合器。本布置提供了封装上的优势，并使发动机能够通过位于变矩器18中的单向离合器62进行传动分离。
本公开的描述本质上仅是示例性的，并且不脱离本公开的主旨的变型旨在落入本公开的范围内。这样的变化不应被视为背离本公开的精神和范围。
