Description

用于电动可变变速器的离合器装置
技术领域
本发明涉及电动可变变速器，更具体地涉及电动可变变速器中的高效的扭矩传递机构。
背景技术
电动可变变速器通常具有输入构件、输出构件和连接到行星齿轮组的不同构件的两个电动机/发电机。离合器允许一个或多个电动可变模式的操作、固定速比模式和纯电动(电池提供动力)模式。电动可变变速器可以多种方式改善车辆的燃料经济性，主要是通过将电动机/发电机中的一个或两个用于车辆制动并且使用再生能量来给车辆提供电动动力，同时关闭发动机。发动机可在怠速时、在减速和制动期间以及在低速或者轻载操作期间关闭以消除由于发动机阻滞产生的效率损失。通过再生制动收集的制动能量(或者在发动机工作期间内产生的电能)在这些发动机关闭期间被使用。用于发动机扭矩或动力的瞬时需求在发动机工作模式下的操作中通过电动机/发电机来补充，这允许在不降低车辆性能的情况下使用较小的发动机。此外，电动可变模式可允许发动机针对给定的动力需求在最优效率点或者附近进行工作。
封装获得期望的工作模式所需的两个电动机/发电机、行星齿轮组以及多个扭矩传递机构，同时满足其它可应用的尺寸限制并且获得相对简单的组装需求是具有挑战性的。
发明内容
本发明提供了电动可变变速器的多种实施方式，它们具有第一和第二电动机/发电机、第一和第二行星齿轮组以及包括转动型离合器和静止型离合器的两个扭矩传递机构。输入构件连接成用于与第一行星齿轮组的环形齿轮一起转动。两个行星齿轮组的行星架中的一个连接成用于与另一个以及与输出构件一起转动。第一电动机/发电机连接成用于与第一行星齿轮组的恒星齿轮一起转动。第二电动机/发电机连接成用于与第二行星齿轮组的恒星齿轮一起转动。
转动型扭矩传递机构是具有同步器的爪形离合器。静止型扭矩传递机构可以是具有同步器的爪形离合器或者可选择单向制动离合器(selectable one-way braking clutch，SOWBC)。这些扭矩传递机构降低部件的复杂性、重量、成本和旋转损失。包括这些离合器的电动可变变速器的部件布置成使变速器的尺寸最小化。

具体实施方式
参考附图，图中类似的附图标记指代类似的部件，图1示出了用于车辆11的动力系10。动力系10包括以驱动方式与电动可变变速器14相连的发动机12。发动机12的输出构件连接成用于驱动变速器14的输入构件16。输入构件16绕着转动轴线18转动并且构建了转动轴线18。
第一电动机/发电机20和第二电动机/发电机22封装在变速器壳体24内并且以可操作方式连接在输入构件16和三个可选变速器输出构件26、26A、26B之间。变速器壳体24仅示出了一部分，并且总体上为环形，环绕着整个变速器14，利用端壁封闭轴向端部，并且端壁上具有用于输入构件16和输出构件26、26A或26B延伸通过的出入口。如下所述，还提供了用作可选变速器输出构件26、26A、26B的可选位置。所有的潜在输出构件26、26A、26B相互连接从而一起转动(即以相同的速度)。变速器输出构件26、26A和26B中的任一个且仅有一个可利用驱动传递组件连接到主减速器(未示出)。与驱动传递组件连接的输出构件的选择取决于车辆内动力系10的封装需求。
第一电动机/发电机20包括固接到变速器壳体24的环形定子30A、支撑在可转动转子毂34A上并且与其一起转动的环形转子32A，转子32A与第一转动轴线18同心。电池(ESD)36、功率变换器(INV)38和电子控制器(CONT)39以可操作方式通过传输导线41A与定子30A相连接以便将电动机/发电机20的功能控制为电动机和发电机，当作为电动机时，存储的电能由电池36提供给定子30A，当作为发电机时，转动的转子32A的扭矩转化为存储于电池36中的电能。控制电动机/发电机而将其作为电动机或者作为发电机的能力是众所周知的。
类似地，第二电动机/发电机22包括固接到变速器壳体24的环形定子30B、支撑在可转动的转子毂34B上的环形转子32B，转子32B与第一转动轴线18同心。电池36、功率变换器38和电子控制器39以可操作方式通过传输导线41B与定子30B相连接以便将电动机/发电机22的功能控制为电动机和发电机。
变速器14还包括第一和第二行星齿轮组40、50。行星齿轮组40具有作为恒星齿轮42的第一构件、作为行星架44的第二构件和作为环形齿轮48的第三构件，行星架44以可旋转方式支撑多个与恒星齿轮42啮合的小齿轮46，环形齿轮48也与小齿轮46啮合。转子毂34A连接成通过环形套筒轴62与恒星齿轮42一起转动。可选的输出构件26连接到行星架44用于与其一起转动。
行星齿轮组50具有作为恒星齿轮52的第一构件、作为行星架54的第二构件和作为环形齿轮58的第三构件，行星架54以可旋转方式支撑多个与恒星齿轮52啮合的小齿轮56，环形齿轮58也与小齿轮56啮合。可选的输出构件26A连接到行星架54用于与其一起转动。转子毂34B连接成通过套筒轴64与恒星齿轮52一起转动。
变速器14包括两个扭矩传递机构。静止型离合器C1，也称为制动器，能够选择性地接合以将环形齿轮58固接到变速器壳体24。离合器C1是可选择单向制动离合器，这将在下面进一步讨论。转动型离合器C2能够选择性地接合以连接恒星齿轮42与环形齿轮58以便使其一起转动。离合器C2是具有同步器的爪形离合器，将参考图6-7对其进行更详细的讨论。本领域普通技术人员将会认识到，仅示意性地示出了在输入构件16之上的一部分变速器14；没有示出行星齿轮组40、50、离合器C1、C2以及其他部件的大致关于输入构件16对称的部分。
形成输出构件26B的环形套筒轴60与输入构件16同心，并且毂构件66和68连接行星架44、54与轴60以及所有的可选输出构件26、26A、26B以便一起转动。毂构件70从输入构件16延伸从而通过轴向延伸部72连接环形齿轮48，用于与其一起转动。
变速器14构造成使得行星齿轮组40沿轴向位于壳体24的径向延伸的端壁(未示出)和电动机/发电机20之间。在图1所示的变速器14中，端壁位于行星齿轮组40的左侧。行星齿轮组50沿着轴向位于电动机/发电机20、22之间。离合器C1沿径向与行星齿轮组50的环形齿轮58对齐并且设置在外侧。离合器C2沿轴向位于电动机/发电机20和行星齿轮组50之间。离合器C2的一部分(即环状部86，在下面进行讨论)连接成通过套筒轴62与恒星齿轮42和转子32A一起转动。离合器C2的另一部分(即齿轮80，在下面进行讨论)连接成通过毂74和轴向延伸部78与环形齿轮58一起转动。
第一前进工作模式通过选择用于离合器C1的反向制动位置并且释放离合器C2而构建。在反向制动位置，离合器C1在转动的两个方向上对转动进行制动。第一前进工作模式是输入分流操作模式，其中行星齿轮组40在差动模式下工作而行星齿轮组50在扭矩倍增模式下工作，发动机12提供扭矩并且电动机/发电机20沿前进方向提供动力。反向的电动可变工作模式以同样的离合器接合方式构建，但是电动机/发电机20沿反向方向提供动力。
第二前进工作模式通过接合离合器C2并且脱开离合器C 1而构建(即选择前进制动位置，由此使得可在前进方向上自由转动但是在转动的反向方向上制动)。离合器C1的前进制动位置在图4中示出。当转子32A的速度为零并且环形齿轮58的速度也是零(由于离合器C1的接合)时发生模式切换，从而切换可在没有扭矩扰动的情况下发生。固定的前进速比通过选择用于离合器C 1的前进制动模式并且接合离合器C2而构建。
在图1中示意性示出了离合器C1，其中切换构件69被选择为前进制动位置。该位置在第一前进模式中选择，并且导致变速器壳体24提供反作用扭矩并且防止环形齿轮58沿前进方向转动。第一前进位置在图4中示意性示出并且参照图4进行更详细的讨论。切换构件69可选择性地移动到反向制动位置，该位置以虚线示出为69A。反向制动位置在第二电动可变模式中选择，并且在图5中示出并且参照图5进行更详细的讨论。在前进制动位置，离合器C1将自由转动以允许环形齿轮58沿前进方向转动。表示离合器C1的外部滚环的第一构件110键接到变速器壳体24上的花键上。第二构件105是离合器C1的内部滚环，其键接到环形齿轮58。可使用卡合环来将离合器C1保持在合适位置。
可用于离合器C1的可选择单向制动离合器的可选实施方式包括可控制机械二极离合器或者可选择滚柱离合器设计或者其他可选择(可逆)单向离合器。离合器C1可通过活塞和阀门以液压方式致动。可设想能够用作SOWBC的多个离合器设计，而本发明不限于这里描述的特定示例实施方式。
已知有多个方法来实施SOWBC。支柱、摇杆、滚柱或撑杆是能够用于选择性接合或脱开离合器的构件的不同特征。图4和5以截面图示出了根据本发明的离合器C1，其选择为前进锁定和反向锁定操作(图5)，以及反向锁定、前进自由转动操作(图4)。在图4和5中，示出离合器C1相对于图3的位置沿逆时针方向旋转了90度。在描述图4和5时，左、右、上和下应当理解为仅仅是相对于图4和5的视图的方向。
离合器C1包括第一构件105、第二构件110、选择器板115、选择器板致动部件120、第一接合构件130、第二接合构件135、两个回复弹簧140和两个接合部件150。第一构件105可以是以公共转动轴线(未示出，但是由图1的输入构件16构建)为中心的可旋转部件。构件105和110可以是环形平板。选择器板115夹持在两个构件之间并且保持与第二构件110相固定。选择器板115包括选择器板致动部件120。选择器板115能够相对于第二构件110移动小的转角，从而提供选择器板致动部件120的校准运动。
在此实施方式中示出为支柱的接合构件130和135以可旋转方式定位到第二构件110，其取向基本上与构件110的半径正交，并且提供离合器C1所承担的联接和脱开功能。每个接合构件130、135当处于向上位置时以固定方式与第一构件105中的接合部件150相配合并且防止第一构件105相对于第二构件110沿一个方向转动。由于通过回复弹簧140施加的力，接合构件130、135通常处于向上为主。选择器板115能够相对于接合构件130、135被致动，从而选择器板致动部件可用来将其中一个接合构件下压到下方位置。停止相对转动的接合作用依赖于相互作用的部件的几何构造。如果其中一个接合构件130、135处于下方位置，那么离合器C1可沿着通常通过现在处于下方位置的接合部件被禁止的方向自由转动。选择器板120可以液压或者电动方式被致动。
图4示出离合器C1的一个接合构件处于下方位置，一个接合构件处于上方位置。接合构件135处于上方位置并且与接合部件150相配合。由此，第一构件105不能相对于第二构件110转动到左侧。然而，接合构件130处于下方位置。对于第一构件105相对于第二构件110的向右转动，接合构件135提供的阻力基本上为零。当相对转动发生并且第一构件105接触接合构件135时，在接合构件135的上部接近水平的表面上的压力造成接合构件135向下转动。接合构件135的此棘轮式运动可在接合部件150转动过随后的接合构件135时持续进行。图4中的离合器C1的状态与切换构件69选择前进制动位置、阻止第一构件105乃至环形齿轮58的反向转动但允许第一构件105乃至环形齿轮58在向前的转动方向上自由转动相一致。
图5示出离合器C1的两个接合构件130和135均处于上方位置。选择器板115被相对于接合构件致动，使得接合构件130和接合构件135均不被致动部件120压下。由此，第一构件105相对于第二构件110在任一方向的转动都不可能发生。图4中的离合器C1的状态与切换构件69A选择反向制动位置、阻止第二构件110乃至环形齿轮58的前进或反向转动相一致。可选地，离合器C 1可配置有允许沿着两个方向自由转动的额外选择状态。
离合器C1的SOWBC设计可比摩擦型静止离合器更节约能量，因为构件105、110的机械接合使得离合器C1的接合能够以较小的液压力完成和维持，或者在选择器板120为电致动的情况下不使用液压力。这可允许变速器14使用较小的、更具有能量效率的液压泵。
可以理解，用于离合器C1的SOWBC的任何可选型号的构件可能要具有多个类似于离合器C 1的特征，每一个都以类似方式致动以允许或阻止在任一方向上的转动，并且全部扭矩通过在SOWBC的特征之间布置的离合器传递。类似的SOWBC特征在摇杆机构领域中是已知的，具有一对位于摇杆的远端的接合构件，能够基于摇杆的摇摆致动并结合在相对构件上的接合部件而类似地阻止或者促成相对转动。滚柱或者撑杆能够可选地在其中一个构件沿径向位于另一个构件内部、并且在构件之间有间隙的构件中使用。滚柱或撑杆可被致动从而在间隙内相互作用以选择性地在一个或两个转动方向上联接构件。
如上所述，作为SOWBC的离合器C 1若应用于自动变速器可减少部件并且增加燃料效率。当离合器C1需要接合时，越过离合器的滑动必须基本上为零。在构件105、110之间可没有相对转动(即滑动)；即离合器C1的两个构件105、110需要静止，或者在其中任何一个均未被固接的实施方式中，需要以相同速度并且沿同一方向转动。
图1的离合器C2是具有同步器的爪形离合器，这在图7中显示得最清楚。离合器C2是典型的具有同步器的三元圆锥型爪形离合器，这对于本领域技术人员是容易理解的。离合器C2包括齿轮80，齿轮80具有键式外部凸缘81和环形部86，环形部86在外部键接在活塞88内并且构造有内部键槽以便在凸缘81和阻断环82的外部花键上滑动。离合器C2还包括形成在齿轮80上的圆锥84。齿轮80连接成与毂74一起转动。毂79连接成与轴62一起转动。毂79上的滚珠和弹簧机构接合在形成于环形部86上的凹穴内。
离合器C2还包括内圆锥环77和外圆锥环85。外圆锥环85具有接合进凸缘81的窗口75内的间隔开的柄脚83。内圆锥环77包括延伸进形成于毂79内的开口的锁定指部73。
离合器C2由供给到施加腔87的液体的液压致动以移动活塞88。通过施加C2，在阻断环82的内表面和外圆锥环83之间产生扭矩，导致外圆锥环83被朝向阻断环82拖动并且旋转，从而每个柄脚83接合各开口75内的凸缘81的侧壁。这又导致内圆锥环77和外圆锥环83的相对表面以及内圆锥环77和圆锥80拖动部件而进行接合。环形部86随后在阻断环82和凸缘81的花键上移动，完成同步过程。当施加腔87充分清空时，回复弹簧89将离合器C2偏置到脱开位置。离合器C2的具有同步器设计的爪形离合器可比摩擦型静止离合器更节约能量，因为环形部86与凸缘81的机械接合使得离合器C2的接合以较小的液压力完成和维持。这可允许使用较小的、更具能量效率的液压泵。可使用其他类型的具有同步器的爪形离合器代替上述三元圆锥型爪形离合器，这取决于离合器上的潜在速度差。
参考图2，具有电动可变变速器14A的动力系10A与动力系10和电动可变变速器14相同，但是SOWBC型的离合器C1替换以爪形离合器和同步器，该离合器称为离合器C1A。如图6中最清楚示出，离合器C1A的爪形离合器部分包括齿轮80A，其具有外部有键的凸缘81A和阻断环82A和套筒86A。环形部86A固定到壳体24。齿轮80A形成圆锥84A。齿轮80A和圆锥84A连接成用于与环形齿轮58和毂74一起转动。圆锥84A构造成配合在阻断环82A内的圆锥型空腔85A内。当环形齿轮58转动时，圆锥84A和阻断环85A之间的摩擦同步阻断环85A和圆锥84A的转速。环形部86A随后滑动，从而阻断环82A和凸缘81A将齿轮80A固接到壳体24上。离合器C1A由供给到施加腔87A的液体液压致动而移动活塞88A。活塞88A迫使环形部86A朝向齿轮80A。当施加腔87A充分清空时，回复弹簧89A移动环形部86A而使其远离齿轮80A，到达脱开位置。离合器C 1A的具有同步器设计的爪形离合器可比摩擦型静止离合器更节约能量，因为环形部86A与凸缘81A的机械接合使得离合器C1A的接合以较小的液压力完成和维持。这可允许在变速器14A中使用较小的、更具能量效率的液压泵。
参考图8，动力系210包括发动机12和电动可变变速器214，电动可变变速器214具有多个同样的部件，这些部件标以相同的附图标记，并且以与图1的变速器14和动力系10及图2的变速器14A和动力系10A所示和所述相同的方式发挥作用。尽管没有在图8中市示出，但是电池36、功率变换器38和控制器39如图1所示和所述那样与定子30A、30B连接。变速器214与变速器14A的相同之处在于，离合器C1A和C2均为具有同步器的爪形离合器。然而，变速器214的其他部件以不同方式设置。
特别是，变速器214构造成电动机/发电机20沿轴向位于壳体24的径向延伸的端壁(未示出)和行星齿轮组50之间。离合器C1A沿径向向外设置并且与行星齿轮组50的环形齿轮58对齐。离合器C2沿径向位于电动机/发电机20内侧，并且沿轴向位于端壁和电动机/发电机20之间。行星齿轮组50沿轴向位于电动机/发电机20和电动机/发电机22之间。电动机/发电机22沿轴向位于行星齿轮组50和行星齿轮组40之间。行星齿轮组40位于电动机/发电机22和壳体24的相对的径向延伸的端壁(未示出)之间。
变速器214具有输入构件216，输入构件216沿轴向与轴260隔开并且与轴260不同心，轴260连接到可选的输出构件226、226A。轴262与输入构件216同轴，并且与其共用相同的旋转轴线218。输入构件216连接到毂构件270和轴向延伸部272以将输入构件216连接成与环形齿轮48一起转动。轴262通过毂构件234C和轴向延伸部234D连接转子毂234A和恒星齿轮42。离合器C2设置在轴向延伸部234D、毂234C和轴262之间。毂构件274与离合器C2连接。套筒轴260与轴262同心并且将行星架构件54和毂构件268和269连接到行星架构件44和输出构件226。套筒轴264连接转子毂234B和恒星齿轮52。可选的输出构件226A从行星架构件54延伸。轴向延伸构件278、毂277和作为环形轴的轴向延伸构件279连接离合器C2和离合器C1及环形齿轮58。轴线延伸构件278限定在行星齿轮组50周围。变速器214可在封装限制要求输出位置(例如输出构件226或226A)需更加朝向中心设置时使用，当输出构件(例如图1中变速器14的输出构件26B)设置成朝向变速器端部时则不使用。
虽然已经详细描述了实施本发明的最佳模式，然而熟悉本发明所涉及领域的技术人员将会认识到所附权利要求范围内的用于实施本发明的多种可选设计和实施方式。
