Description

具有机械反转功能的混合动力车辆传动系统
技术领域
本发明涉及一种用于具有电动-机械反向驱动动力流路径的混合动力电动车辆的动力系统。
背景技术
已知的具有所谓的动力分配特征的混合动力电动车辆，有时被称为动力分配“混合动力电动车辆(HEV)”的动力系统，包含自内燃机和电动牵引马达至车辆牵引轮建立动力流路径的齿轮装置，该齿轮装置包括行星齿轮单元。这类动力系统的一个示例在美国专利6,991,053以及美国专利RE38017中被公开，美国专利6,991,053已转让给本发明的受让人。
在这些参考文献中公开的动力系统包括行星齿轮单元和直接连接到行星齿轮架上的内燃机。行星齿轮单元的恒星齿轮可驱动地连接到发电机。行星齿轮单元的环齿轮作为动力输出部件，通过扭矩传动齿轮装置将驱动动力传递到牵引轮上。马达也通过该传动齿轮装置将动力传递到车辆的牵引轮上。发电机和马达以及高压蓄电池电连接在一起。
在发动车辆时，发电机可被指令向动力系统提供动力辅助。然后，电力被供给到蓄电池，蓄电池再驱动马达。
在反向驱动期间，马达可以反向运转从而为车辆的牵引轮提供反向扭矩。在反向驱动期间，发电机不能像马达一样运转以提供动力辅助，因为除了可以使发动机曲轴旋转的很小的扭矩外，没有反扭矩将发电机扭矩传送到环齿轮。
此前已经作出了通过在马达的扭矩流路中提供额外的齿轮装置来提高反向驱动性能的尝试。该类动力系统的一个示例可以从已被转让给本发明的受让人的美国专利7,128,677中看到。由于需要空间来容纳所需的额外齿轮装置，该种类型的动力系统将会变得较长。它将难以被安装到现有的机动车辆环境中。因此，这也就是本发明的目的所在，即：通过在提供机械的反向动力流路径的同时，提供无需增加动力系统的长度且能够被安装到常规的机动车辆环境的增强的反向驱动扭矩功能，克服公知的混合动力电动车辆动力系统的缺陷。
发明内容
本发明的一个实施例包含具有位于公共轴线上的动力分配行星齿轮单元和内燃机的动力系统。第二齿轮单元可被设置于发动机和动力分配齿轮组的公共轴线上。该第二齿轮组是位于动力分配齿轮组和发动机之间的扭矩反转行星齿轮组。扭矩反转行星齿轮组的动力输出元件连接到扭矩传动齿轮总成，该扭矩传动齿轮总成处于从马达到车辆牵引轮的扭矩流路径中。扭矩传动齿轮的齿轮元件可驱动地连接到将扭矩分配到车辆牵引轮的主减速器上。
在设计思想上，扭矩反转齿轮组包括位于动力分配齿轮组和发动机的公共轴线上的正向和反向耦合离合器。当马达以正向驱动模式运行时，正向驱动扭矩可以被分配到主减速器齿轮装置以补充马达扭矩。耦合离合器被设置为，当动力系统以反向驱动模式运行时，将反向驱动扭矩从动力分配齿轮组分配到扭矩传动齿轮总成，以补充马达的反向驱动扭矩。
附图说明

图3是用于选择性地将正向、反向耦合离合器转换为反向驱动状态和正向驱动状态的起动元件总成的局部横截面视图；以及
图4是图2所示的动力系统的局部横截面视图，其中发电机和马达与扭矩反转齿轮装置及正向和反向耦合离合器一起安装到动力系统中，以减小动力系统的尺寸。
具体实施方式
图1以10示意性表示发动机。发动机10的曲轴通过减震器12连接到一对行星齿轮组的中间轴14上。第一行星齿轮组为动力分配齿轮组，总体上以16表示。其包括环齿轮18，恒星齿轮20和齿轮架22。该齿轮架可驱动地连接到中间轴14上。连接到恒星齿轮20的齿轮元件24与齿轮元件28相啮合，该齿轮元件28又与用于以34标记的发电机的轴32的轴线上的齿轮元件30相啮合。轴32与中间轴14相平行。
发电机34包括固定到传动系统壳体上的定子36。发电机转子38连接到轴32上。
齿轮架22可旋转地支承与环齿轮18和恒星齿轮20驱动啮合的行星小齿轮。环齿轮18通过套轴40连接到扭矩反转行星齿轮组44的恒星齿轮42上。齿轮组44的环齿轮46通过套轴可驱动地连接到传动齿轮48上。扭矩反转行星齿轮组44的齿轮架50支承可与环齿轮46和恒星齿轮42相啮合的行星小齿轮。其直接连接到套轴52上。
正向和反向耦合离合器总成54包括可移动的离合器元件56，其可沿中间轴14的中心轴线向左或向右移动到其花键联接处。离合器元件56是具有内花键和外花键的套筒。离合器元件56的外花键与标记60所示的直接连接到环齿轮46的离合器内齿58相啮合。
尽管所公开的正向和反向耦合离合器54是爪形离合器，其也可以是不同的设计，例如公知设计中的同步器型离合器。此外，套筒56上的离合器外齿可用来代替离合器外齿，离合器内齿58和62可被离合器外齿代替。
正向和反向耦合器总成54还包括离合器内齿62，如标记64所示，其可固定或锚定接地到标记66示意性所示的传动系统壳体上。
当套筒56向右移动时，套筒56的外齿可驱动地与锚定轴52和齿轮架50的离合器内齿62啮合。
传动齿轮48形成标记68所示的传动齿轮总成的一部分。齿轮48啮合包括齿轮元件72的副轴齿轮装置的齿轮元件70。主减速器动力输入齿轮74啮合齿轮元件72。主减速器通过差动总成以惯常的方式连接到车辆的牵引轮。传动齿轮元件70与直接连接到牵引马达80的转子78上的传动齿轮76啮合。该牵引马达包括连接到传动系统壳体的固定定子82。
标记90所示的高压蓄电池利用高压总线86与发电机和马达电连接。控制局域网络(CAN)将传动系统连接到蓄电池90与标记92所示的车辆系统控制器和动力系统控制模块。传动系统包含马达80、行星齿轮组16和44及发电机34，以及传动齿轮装置。如标记94所示，车辆系统控制器和动力系统控制模块将适当的指令传递到发动机10。
在图1所示的动力系统运转期间，发动机扭矩通过减震器12从发动机10传递到中间轴14和行星齿轮组16的齿轮架22上。齿轮组16的恒星齿轮20在分离动力驱动模式期间通过传动齿轮24、28和30将扭矩传送到发电机转子轴32。在分离动力运行模式运行期间，电能从蓄电池90分配到马达80的定子82上，电荷能量从发电机34分配到蓄电池90上。
在分离动力模式下运行期间，当发电机34被驱动时，恒星齿轮20为行星齿轮组16提供反扭矩。行星齿轮组16的环齿轮18作为用于行星齿轮组16的动力输出元件。环齿轮扭矩通过环绕主轴14的套轴40分配到扭矩反转行星齿轮组44的恒星齿轮42。
如前所述，齿轮组44的齿轮架50直接连接到套轴52上。用于耦合离合器总成54的离合器套筒56可滑动地与套轴52相啮合。套筒56具有可滑动地与套轴52上的外花键啮合的内花键。当套筒56向左移动时，套筒56上的外齿与离合器元件58的内齿啮合。离合器元件58被扭矩反转行星齿轮组44的元件60承载。因此，齿轮组44的齿轮架50和环齿轮46被锁定在一起，这就提供了统一的传动比。标记18处的环齿轮扭矩因而通过套轴40、通过锁定的齿轮组44被直接传送到传动齿轮48。因而，主减速器差速齿轮74被副轴齿轮元件70和72驱动。在该通过机械扭矩流路径将扭矩从发动机分配到主减速器差速齿轮装置的同时，来自马达80的马达扭矩被传递到传动齿轮76上。当马达80在正向驱动方向被驱动时，马达扭矩即与从发动机传递的机械扭矩相结合。
当耦合离合器总成54的套筒56向右移动时，套筒56的外齿啮合接地的内齿62，如标记64和66所示。这将导致正向和反向耦合器的齿轮架50被制动，从而提供反作用扭矩。当用于环齿轮18的扭矩被传递到恒星齿轮42时，环齿轮46被反向驱动。从而，反向驱动扭矩被传递到传动齿轮48和副轴齿轮元件70和72。该反向驱动扭矩被添加到从马达80传递到传动齿轮76的扭矩中，从而提供增强的反向驱动性能。此时马达受车辆系统控制器和动力系统控制模块92指令，响应车辆系统控制器和动力系统控制模块接收的操作者的输入，从正向驱动模式转换为反向驱动模式。
在设计思想上，扭矩反转行星齿轮组44相对于发电机34、马达80、行星齿轮组16以及传动齿轮定位，使得在发动机曲轴的轴线方向和垂直于发动机轴线的横向方向上的总尺寸不会增加。从而，动力系统的整个总成可以与例如前述的′053专利和′017专利所示类型的动力系统一样容易地安装到车辆环境中。
图2表示本发明的可选实施例。其具有与图1实施例的元件相应的元件。用于这些相应元件的相同标记已表示在图1和图2中，尽管图2中所用的数字增加了撇。
在图2中的实施例中，来自动力分配行星齿轮组16’的环齿轮18’的扭矩输出被传递到套轴94。扭矩反转行星齿轮组44’的环齿轮96连接到耦合离合器齿98。
如图所示，齿轮组44’的齿轮架100锚定在传动系统壳体上。齿轮组44’的恒星齿轮102连接到套轴94。
正向和反向耦合离合器总成104具有包括带离合器内齿108和110的滑动套筒的离合器元件。离合器内齿108可滑动地与套轴114上的离合器外齿112啮合。内花键齿110可移动至与外花键齿98和形成于套轴94上的外花键齿116不相啮合。
当发动机扭矩驱动齿轮架22’时，正向驱动扭矩被传递到套轴94。如果正向和反向耦合离合器套筒106移动到左方，驱动扭矩就会被传送到在正向驱动方向上驱动主减速器齿轮装置的传动齿轮46’上。该正向驱动扭矩被传递到传动齿轮79’的牵引马达扭矩扩大。在此运转模式下，图2所示的动力系统以与前述的′053专利和′017专利所公开的动力系统相同的正向驱动功能运转。
在反向驱动期间，耦合离合器套筒106向右移动。这就使离合器套筒106和耦合器齿98直接连接，从而使得扭矩从环齿轮96直接传递到套筒114上。由于齿轮架100被锚定在传动系统壳体上，环齿轮96和套筒114被反向驱动。当马达被车辆系统控制器设定以反向驱动模式运转时，从齿轮组44’传递到副轴齿轮元件70’的反向扭矩与从传动齿轮76’传递到副轴齿轮元件70’的反向驱动马达扭矩结合在一起。因此，当来自齿轮组44的扭矩加到通过牵引马达80’实现的反向驱动扭矩时，就会得到增强的反向驱动性能。
图3以示意性的方式表示用于图1中的正向和反向耦合器及用于图2中的正向和反向耦合器的正向和反向驱动移换装置。其包含标记118部分地表示的换档拨叉。该换档拨叉118具有通过轴衬124可滑动地安装到支承轴122的衬套120。支承轴122的端部被支承在传动系统壳体部分上，如标记126和128所示。
换档拨叉套承载凸轮随动件130，该凸轮随动件接收在形成于套筒134上的螺旋形凹槽132中。该套筒134被固定在可旋转的支承轴136上。支承轴136的右端被支承在传动系统壳体部分128上的支承套筒的开口上，如标记138所示。合适的支承轴承结构140可以被用来达到此目的。
电动可逆伺服马达142利用适当的附加装置(图中未示)安装在传动系统壳体上。该伺服马达具有安装于标记144所示的蜗轮轴上且被蜗轮轴驱动的蜗轮。被马达142驱动的蜗轮可驱动地与标记146所示的可驱动地连接到轴136上的蜗杆小齿轮啮合。因此，当马达142驱动轴136时，螺旋形套筒134将会旋转，从而导致换档拨叉套120上的随动件130根据伺服马达142的运动方向的向右或向左移动。这样，图1实施例中的离合器套筒56以及图2实施例中的离合器套筒106可以在轴122的轴线方向上向右或向左移动。
图2的实施例在图4中以更完整的形式表示。如图4中所见，扭矩反转行星齿轮组与正向和反向耦合离合器位于发电机34’和马达82’之间，这样就不需要增加动力系统的轴向尺寸。也不增加动力系统在轴向尺寸的横向上的尺寸。能够容纳例如′053专利中或′017专利中所公开的动力系统的混合动力电动车辆动力系统设备也能够容易地容纳本发明的动力系统。
图4以标记119表示未在图2中具体表示的发动机曲轴。曲轴119直接连接到传动系统扭矩限定离合器121。如果发动机扭矩超越校准的限度值，离合器121将滑脱。如前所述，通过扭矩限定离合器121传送的扭矩通过减震器12’分配到轴14’。
在图4中，与图2中的齿轮元件70’相应的副轴传动齿轮元件为串联式齿轮70a’和70b’。这些串联式齿轮以与图2所示的单独齿轮70’相同的方式运转。
串联式齿轮70a’和70b’分别由壳体部分127和66’中的锥形推力轴承123和125端承。如标记136所示，这两个壳体部分可以被栓接在一起，形成一体式壳体总成。
轴14’由轴承129及壳体部分66’中的轴承131端承。轴承131设置在轴14’和形成或承载恒星齿轮102与离合器齿116的套轴137之间。套轴137由壳体部分66’中的轴承139支承。套轴137也受轴承141支承。轴承143支承轴14’上的传动齿轮46’。
如标记133和135所示，由马达80’驱动的套轴111分别被端承在壳体部分127和66’中。传动齿轮76’形成在或者连接在套轴111上。如图4所示，用于发电机驱动传动齿轮总成26’的传动齿轮24’、28’以及30’在壳体部分66’中被端承。
本发明的实施例已被公开，然而，对本领域技术人员而言，不脱离本发明的范围对其做出修改将是显而易见的。所有这些修改和等同物应由本发明的权利要求书所覆盖。
