Description

用于动力分流混合动力传动装置的锁止离合器
技术领域
本公开涉及用于机动车辆的自动传动装置的领域。更具体地讲，本公开关于动力传动装置中的齿轮、离合器、马达的布置以及它们之间的相互连接。
背景技术
许多车辆在宽范围的车速(包括前进运动和倒车运动两者)下使用。然而，某些类型的发动机只能在窄的速度范围内高效运转。所以，能够以多个传动比(speed ratio)高效地传递动力的传动装置被频繁地使用。当车辆处于低速时，传动装置通常以高传动比运转，使得传动装置使发动机扭矩倍增，用于改善加速。在高车速时，使传动装置以低传动比运转允许与安静、燃料高效的巡航相关联的发动机转速。通常，传动装置具有安装至车辆结构的壳体、由发动机曲轴(通常，经由起步装置，诸如变矩器)驱动的输入和通常经由差速器组件驱动车轮的输出，在车辆转弯时，差速器组件允许左车轮和右车轮以稍微不同的转速旋转。在具有横向安装的发动机的前轮驱动车辆中，发动机曲轴轴线通常从车轴轴线偏移。
混合动力电动传动装置通过包括一个或更多个可逆电机和一些类型的电能储存器(诸如电池)进一步降低燃料消耗。混合动力电动传动装置以多种方式改善燃料效率。大多数的内燃发动机在以相对高的动力设置操作时最高效。混合动力电动传动装置允许发动机在比推进所需的动力更高的电力水平下运转部分时间，同时将多余电力储存在电池中。随后，在其它时间，发动机关闭，并使用储存的能量推进车辆。尽管发动机产生相同数量的总能量，但它以更高的平均效率运转。此外，在施加制动时，可逆电机可捕获车辆动能并将其储存在电池中，以在之后用于推进。当车辆静止并且因此不需要推进时，可关闭发动机以省去否则可被用于保持怠速的燃料。电动马达提供了在发动机关闭的情况下推进车辆和在必要时迅速重启发动机的能力。

具体实施方式
在此描述本公开的实施例。然而，应理解，公开的实施例仅为示例，其他实施例可采取各种和替代的形式。附图无需按比例绘制；可夸大或最小化一些特征以显示特定部件的细节。因此，在此公开的具体结构和功能细节不应解释为限制，而仅作为用于教导本领域技术人员以多种形式利用本发明的代表性基础。如本领域的普通技术人员将理解的，参考任一附图示出和描述的各种特征可与在一个或更多个其他附图中示出的特征组合，以产生未明确示出或描述的实施例。示出的特征的组合为典型应用提供代表性实施例。然而，与本公开的教导一致的特征的各种组合和变型可以期望用于特定应用或实施方式。
如果一组旋转元件被约束为在所有工况下以相同的转速围绕相同的轴线旋转，则这组旋转元件彼此固定地结合。可通过花键连接、焊接、压装、对同一固体进行机加工或其它方式固定地结合旋转元件。可以出现固定结合的元件之间的旋转位移的轻微变化(例如，由于冲击或轴柔量(shaft compliance)导致的位移)。彼此完全固定结合的一个或更多个旋转元件可以称为轴。相比之下，每当换挡元件完全接合并且它们在至少一些其它工况下具有不同的转速，换挡元件约束两个旋转元件以相同的速度围绕相同轴线旋转时，两个旋转元件通过换挡元件选择性地结合。如果在两个可旋转元件之间存在固定的成比例的转速关系，则两个可旋转元件被可驱动地连接或结合。
通过选择性地将旋转元件结合到固定的壳体而保持旋转元件不旋转的换挡元件称为制动器。选择性地将两个或更多个可旋转元件彼此结合的换挡元件称为离合器。换挡元件可以是主动控制的装置(诸如，液压或电动驱动的离合器或制动器)或者可以是被动装置(诸如，单向离合器或制动器)。换挡元件可以是主动接合装置(诸如，齿式离合器)或者可以是能够在存在相对旋转的元件之间传递扭矩的摩擦装置。如果两个元件固定地结合或者选择性地结合，则这两个元件结合。
齿轮传动布置是齿轮传动元件和换挡元件的集合，被构造为在一组轴之间施加特定的转速关系。如果施加转速关系与任何的换挡元件的状态无关，则该转速关系是被齿轮传动布置固定施加的。如果仅当齿轮传动布置的特定换挡元件完全接合时施加转速关系，则该转速关系是被齿轮传动布置选择性施加的。当轴沿着一个方向旋转时，轴的转速为正，当轴沿着相反的方向旋转时，轴的转速为负。当第一轴与第二轴的转速比率被约束为预定值时，第一轴和第二轴之间存在成比例的转速关系。如果第二轴的转速与第一轴的转速的比率在零和一之间，则第一轴与第二轴之间的成比例的转速关系是低速(underdrive)关系。类似地，如果第二轴转速与第一轴转速之间的比率大于一，则第一轴和第二轴之间的成比例的转速关系是超速关系。当在下列情况时，在有序排列的轴中存在线性转速关系：i)在有序排列的轴中的第一个轴和最后一个轴被约束为具有最极端的转速，ii)其余轴的转速分别利用预定加权被约束为第一个轴和最后一个轴的转速的加权平均，以及iii)当轴的转速不同时，轴的转速被约束为以所列顺序增大或减小。
参照图1，混合动力电动车辆(HEV)包括动力分流动力传动系统10。车辆可包括用于控制电牵引电池14的车辆系统控制器(VSC)和动力传动系统控制模块(PCM)12。电池14可具有双向电连接，从而电池14接收和储存电能，并且还将电能供应到电牵引马达16。控制器12还可控制内燃发动机(ICE)18的操作。马达16和发动机18两者均能够给传动装置20提供动力，传动装置20最终将扭矩传递给车辆的车轮。
发动机18将动力传递到扭矩输入轴(诸如，曲轴22)，扭矩输入轴通过(例如)单向离合器连接到行星齿轮组24。曲轴22对行星齿轮组24提供动力，行星齿轮组24包括环形齿轮26、中心齿轮28和行星齿轮架组件30。曲轴22可驱动地连接到齿轮架组件30以对行星齿轮组24提供动力。行星齿轮组24可将扭矩分配到中间轴34。
中心齿轮28可驱动地连接到发电机32。发电机32可与中心齿轮28接合，使得发电机32可随中心齿轮28旋转或不随中心齿轮28旋转。在单向离合器将发动机18结合到行星齿轮组24时，发电机32作为对行星齿轮组24的操作的反作用元件而产生能量。从发电机32产生的电能可通过电连接件36传递到电池14。电池14还以公知的方式通过再生制动接收并存储电能。电池14将储存的电能供应到马达16，以用于操作。从发动机18输送到发电机32的动力的一部分还可直接传递到马达16。电池14、马达16和发电机32均通过电连接件36以双向电力流动路径互相连接。
车辆可仅由发动机18提供动力，仅由电池14和马达16提供动力，或者由发动机18与电池14和马达16的组合提供动力。在第一操作模式下，发动机18被启用，以通过行星齿轮组24输送扭矩。环形齿轮26可通过中间轴34将扭矩分配给阶梯比齿轮38，阶梯比齿轮38可(例如)包括啮合的齿轮元件40、42、44和46。齿轮42、44和46安装在副轴上，齿轮46将扭矩分配给齿轮48。然后，齿轮48将扭矩分配给扭矩输出轴或副轴50。在第一操作模式下，马达16也可被启用，以辅助发动机18。在马达16用于辅助时，齿轮52将扭矩分配给齿轮44和副轴。
在第二操作模式或EV模式下，发动机18被停用或以其它方式被防止将扭矩分配给扭矩输出轴50。在第二操作模式下，电池14为马达16供电，以通过阶梯比齿轮38分配扭矩并将扭矩分配给扭矩输出轴50。
扭矩输出轴50连接到差速器和车轴机构56，差速器和车轴机构56将扭矩分配给牵引车轮58。控制器12控制电池14、发动机18、马达16和发电机32，以在第一操作模式或第二操作模式下将扭矩分配给车轮58。
如前所述，存在用于传动系的两个动力源。第一动力源是发动机18，发动机18将扭矩输送到行星齿轮组24。另一动力源仅涉及电驱动系统，该电驱动系统包括马达16、发电机32和电池14，其中，电池14用作用于发电机32和马达16的能量储存介质。发电机32可由行星齿轮组24驱动，并且可以可选地用作马达并将动力输送到行星齿轮组24。
现参照图2至图4，动力传动系统10还可包括锁止离合器60。锁止离合器60可适于锁止传动装置20的行星齿轮组24。在图2中示出的至少一个方案中，锁止离合器60适于锁止环形齿轮26和行星齿轮架组件30。在图3中示出的至少一个其它方案中，锁止离合器60适于锁止中心齿轮28和行星齿轮架组件30。在图4中示出的至少一个其它方案中，锁止离合器60适于锁止环形齿轮26和中心齿轮28。
锁止离合器60对行星齿轮组24的锁止使环形齿轮26、中心齿轮28和行星齿轮架组件30的齿轮啮合并“锁止”，从而将扭矩从发动机18传递到传动装置20。通过这种方式，行星齿轮组24的元件以与1:1传动比一致的方式旋转。锁止离合器60对行星齿轮组24的锁止可减小或消除行星齿轮组24中的啮合损失，从而在处于锁止构造中时提高传动效率。
传动装置20可包括可设置在(例如)位置L1、位置L2和位置L3处的齿轮传动布置。
现参照图3，第一齿轮传动布置70可包括第一行星齿轮组72，第一行星齿轮组72包括环形齿轮74、中心齿轮76和行星齿轮架组件78。第一齿轮传动布置70可包括第二行星齿轮组80，第二行星齿轮组80包括环形齿轮82、中心齿轮84和行星齿轮架组件86。

在至少一个方案中，第一齿轮传动布置70不包括离合器94或制动器98。通过这种方式，第一齿轮传动布置70可在没有反向离合器的情况下提供三个前进速度。
通过第一齿轮传动布置70的离合器和制动器的选择性接合在输入轴62与输出轴50之间建立多个动力流动路径。如表1所示，接合两个或三个相组合的换挡元件在输入62与输出50之间建立四个前进传动比和一个倒车传动比。X指示该换挡元件需要用于建立动力传输路径。(X)指示该换挡元件可在该传动比下接合，但不需要用于建立动力传输路径。
