Description

包括具有多种不同操作模式的变速器的驱动系统
技术领域
本发明涉及包括用于电动车辆和混合电动车辆的变速器的驱动系统或动力传动系。
背景技术
电池电动车辆(BEV)是一种使用存储在充电电池组中的化学能的电动车辆(EV)。BEV使用电动马达和马达控制器代替内燃机(ICE)进行推进。
如美国专利第8,167,754、8,226,515、8,246,501、8,251,850和8,398,514号中所述，为了生产更高效的车辆，通用的混合动力车辆动力传动系将电动马达和常规发动机结合起来。来自发动机和电动马达的扭矩通常通过变速器传递到车辆的从动轮。混合动力车辆动力传动系的效率通常与时间百分比以及除了电动马达之外或代替电动马达必须运行发动机为车辆提供动力期间的行驶条件的类型相关。
一些混合动力传动系采用单个电动马达与发动机相结合。在这样的动力传动系中，变速器的输出、因此车辆速度与发动机和电动马达的速度和扭矩直接相关。其他混合动力传动系采用两个电动马达与发动机结合来为车辆提供动力。
利用发动机和两个电动马达的混合动力传动系可将发动机和电动马达连接到变速器，使得可独立于车辆速度和期望的加速度之外来选择发动机的扭矩和速度。发动机的这种控制通常通过改变来自两个电动马达的单独的扭矩贡献来实现。因此，利用与两个电动马达结合的发动机的混合动力传动系可提供来自发动机和两个马达中的每一个的合适的扭矩贡献并提供改进的总体车辆效率。
描述混合动力变速器或动力传动系的其他美国专利包括：美国专利第5,847,469、5,856,709、5,934,395、6,019,699、6,306,057、6,344,008、7,201,690、7,223,200、7,237,634、7,255,186、7,393,296、7,397,296、7,426,971、7,614,466、7,621,359、7,633,247和7,690,455号。
被转让给与本申请相同的受让人并与本申请相关的美国专利文件包括美国专利第8,813,929、8,888,637、9,109,636、9,186,977、9,303,699和9,441,708号以及美国公开申请第2014/0100071、2015/0000442、2015/0014116、2018/0106304、2018/0231105和2017/0313173号。所有上述共同转让的专利文献的公开内容全部引入本文作为参考。
转让给本申请受让人的一些上述相关专利文献公开了一种2位线性马达eCMD(电可控机械二极管)。当两个座圈(即，凹口板和槽板)旋转时，该设备是动态单向离合器。线性马达或致动器通过定子产生的磁场移动，进而使与支柱耦合的柱塞移动。致动器具有永磁体环，其将离合器锁定在打开和关闭两种状态。功率仅在从一个状态到另一个状态的转换期间被消耗。一旦进入所需状态，磁体就会锁住并且电源切断。
美国专利文献2015/0000442和美国专利第9,441,708号公开了三位的、线性马达的、磁锁的双向CMD。
插电式混合动力电动车辆(PHEV)、插电式混合动力车辆(PHV)或插电式混合动力是利用充电电池或另一种能量存储设备的混合动力车辆，其可通过将插头连接到外部电源(通常为普通壁式电插座)而恢复到完全充电。PHEV与具有电动马达和内燃机(ICE)的传统混合动力电动车辆以及具有连接到电网的插头的全电动车辆具有相同的特征。如今，道路上的大多数PHEV都是乘用车，但也有PHEV版本的商用车和厢式货车、多用途卡车、公共汽车、火车、摩托车、滑板车和军用车辆。
机动车辆动力传动系中的多比(即阶梯比)自动变速器调节扭矩源和驱动轴之间的传动比以满足在动态变化的驾驶条件下的驾驶性能要求。通过在所谓的“待分离离合器(off-going clutch)”(“OGC”)释放时接合所谓的“待接合离合器(on-coming clutch)”(“OCC”)来实现传动比变化。可以称为变速器摩擦元件或制动器的这些离合器建立和解除从内燃机到车辆牵引轮的功率流路径。在车辆加速期间，对于指定的发动机节气门沉降，总速比(即变速器输入轴速度与变速器输出轴速度之比)会随着车速的增加而减小。这是一种升档。
在同步升档的情况下，OCC接合，以减小传动比(即，总速比)和扭矩比(输出扭矩与输入扭矩之比)。同步升档事件可以分为三个阶段，它们可以被称为准备阶段、扭矩阶段和惯性阶段。扭矩阶段是控制OCC的扭矩将其减小到不显著的水平以使其分离的时间段。同时，在扭矩阶段期间，控制OCC从不显著的水平开始增大，从而根据传统的升档控制使OCC开始接合。
离合器的接合和分离时刻使得穿过齿轮系的两条扭矩流路径被瞬时激活，从而使变速器输出轴处的扭矩输送瞬间降低。这种情况(可以称为“扭矩洞”)会发生在OGC分离之前。车辆乘员会将较大的扭矩洞感知为令人不愉快的换档冲击。准备阶段是扭矩阶段之前的时间段。惯性阶段是扭矩阶段之后的、OGC由于保持能力大大降低而开始滑动的时间段。
自动手动变速器(AMT)是一种用于机动车辆的自动换档变速器，其通过移除变矩器而提高了机械效率。这种自动手动变速器通常包括多个动力操作的致动器，它们由变速器控制器或某种类型的电子控制单元(ECU)来控制，以自动地切换对啮合的齿轮的接合进行控制的同步的离合器，这在传统的手动变速器中是常见的。在AMT的换档过程中，发动机扭矩通过离合器与车辆断开连接。在变速器改变传动比的同时扭矩中断。改变传动比后，重新应用离合器将发动机再次连接至传动系。这种方法的问题是，在扭矩中断期间驾驶员在驾驶室中被向前猛推，然后在发动机再次与传动系连接时被向后猛推。这种换档事件可以长达一秒。这是一种不受欢迎的“换档感觉”。此外，在这种过渡期间车辆没有加速，产生不期望的驾驶状况(拉出进入车流、汇流等)。
美国专利第7,942,781号公开了一种高效的车辆变速器。该变速器包括变速器壳体、包括被支撑为在壳体内进行旋转的第一元件和第二元件的一组扭矩传递元件以及用于在换档期间响应于电信号而改变至少一个元件的角速度以获得所需的传动比的电动马达。至少一个非摩擦式可控耦合器组件分别具有用于将第一元件耦合至第二元件或壳体的耦合状态以及用于将第一元件与第二元件或壳体解耦的解耦状态。至少一个耦合器组件进行非液压式控制以改变状态，从而维持期望的传动比。
针对本申请的目的，术语“耦合器”应解释为包括离合器或制动器，其中一个板可驱动地连接至变速器的扭矩传递元件，而另一个板可驱动地连接至另一扭矩传递元件或者相对于变速器壳体被锚固且保持静止。术语“耦合器”、“离合器”和“制动器”可以互换使用。
美国公开专利申请第2018/0156332号公开了包括用于电动车辆和混合动力电动车辆的变速器在内的驱动系统或动力传动系。3位线性马达、2路离合器(即CMD)包括在该变速器中。公开了一种电动3速AMT。
线性马达是一种电动马达，其定子和转子“展开”，使得其不会产生扭矩(旋转)而是在其长度上产生线性力。最常见的工作模式是作为洛伦兹型致动器，其中施加的力与电流和磁场成线性比例。美国公开申请2003/0102196公开了一种双向线性马达。
线性步进马达用于需要在低质量有效载荷的情况下快速加速和高速移动的定位应用。机械简单和精确的开环操作是步进线性马达系统的附加特征。
线性步进马达通过与旋转步进马达相同的电磁原理工作。固定部件或压板是在所需行程长度上延伸的被动有齿钢条。永磁体、有齿的电磁体和轴承都包含在移动元件或活塞中。活塞沿压板双向移动，确保响应于励磁绕组中电流状态的离散位置。一般来说，马达是两相位的，但是可以采用更多数量的相位。
线性步进马达在现有技术中是公知的，并且根据已建立的磁理论原理工作。线性步进马达的定子或压板部件由细长的矩形钢条构成，其具有在待横移的距离上延伸的多个平行的齿并且以用于马达的所谓活塞部件的轨道的方式起作用。
压板在马达的操作期间是完全被动的，并且所有磁体和电磁体都被结合到活塞或电枢部件中。活塞响应于其励磁绕组中的电流状态而沿着呈现离散位置的压板双向移动。
美国公开专利申请第2019/0225073号公开了一种用于车辆的动力传动系组件，其包括第一马达和第二马达。具有功率输出轴的功率分流组件将第一马达和第二马达连接到功率输出轴。功率分流组件选择性地接收来自第一马达和第二马达的功率输出，其中功率分流组件限定向功率输出轴提供扭矩的多种操作模式。动力传动系组件还包括旁路功率轴，其操作性地连接在第二马达和功率输出轴之间，使得第二马达使用旁路功率轴向功率输出轴提供扭矩。
eCVT功能提高了变速器效率，并且通常由专用混合动力变速器(DHT)而不是AMT提供。由于成本原因，AMT通常是优选的，因为美国专利文献2018/0156332的AMT具有单个致动器(即，三位线性致动器)。

变速器10还包括采用三位DCC的形式的(即，用于模式选择的动态可控离合器，见图9的图表)总体上以20表示的非摩擦式、可电控的第一耦合器组件，其包括对两个离合器进行控制的三位线性致动器(即，步进马达)。这种DCC通常可从密歇根州萨吉诺的MeansIndustries获得。在美国公开专利申请第2018/0156332号中描述了一种优选的3位线性步进马达，该专利申请的全部内容通过引用并入本文。
线性马达的第一位置由标记为“EV”的节点表示，线性马达的第二位置由标记为“HEV”的节点表示，线性马达的第三位置由标记为“GAS”的节点表示。在图1中，节点“HEV”接地到变速器10的固定构件22，例如变速器壳体。
总体上用24表示的可选的非摩擦式、可电控的制动器组件(即图9的图表中的可选制动器)允许停车和坡道驻车(HH)，如图9的图表所示。优选地，制动器组件24包括一对可电控的螺线管。优选的制动器组件24被描述在本文提及的许多专利文献中并且通常可从Means Industries获得。
变速器10还包括一组齿轮，其包括分别与变速器输出轴32连接的第四元件、第五元件、第六元件和第七元件，例如齿轮25、26、28和30。齿轮25、26、28和30被安装为用于与输入轴18一起旋转。

马达A通过齿轮46和48驱动输出轴32。使用两个电动马达而不是单个电动马达在不对牵引和性能造成任何损害的情况下对于指定的电动马达实现更小的电动马达和更低的功率要求。
根据本发明构造的驱动系统或动力传动系的每个实施方式可利用主控制器或TECU(变速器电子控制单元)(未示出)和一个以上的控制器(未示出)。
总体上，TECU通过一个以上的控制器提供和调节功率，以驱动各种旋转式和线性式马达。每个控制器通常具有包括电路的微控制器(即MCU)。每个控制器通常在基于车辆的总线上或通过该总线从远程电子控制单元(TECU)接收指令信号。
优选地，由TECU和/或控制器使用的控制逻辑主要在通过基于微处理器的控制器或微控制器(即MCU)执行的软件中实现。当然，控制逻辑可以根据具体应用通过软件、硬件或软件和硬件的组合来实现。当通过软件实现时，控制逻辑优选地设置在具有表示由计算机执行的指令的存储数据的计算机可读存储介质中。一个或多个计算机可读存储介质可以是利用电子设备、磁性设备和/或光学设备临时地或永久地存储可执行的指令和相关联的校准信息、操作变量等的多种已知物理设备中的任何一种。
TECU和一个以上的控制器经由诸如本地互连网络(LIN或CAN)线的车辆总线或能够双向通信的总线进行连接。LIN是多种可行的车载局域网(LAN)通信协议之一。可以在TECU和每个控制器之间设置电源线和接地线。每个控制器通常包括MCU内的收发器接口、MCU内的微处理器及其控制逻辑、马达驱动或驱动器以及电源。每个控制器可以集成或物理地耦合在变速器壳体内，同时将TECU设置成与壳体相距一定距离。
每个马达控制器的MCU通常包括存储器，并且可以被配置为包括CPU、ROM、RAM等的常规微型计算机或者被配置为硬连线逻辑电路。
虽然以上描述了示例性实施方式，但这些实施方式并不意味着描述了本发明的所有可能形式。相反，说明书中使用的词语是描述性词语而不是限制性词语，并且应当理解的是在不脱离本发明的精神和范围的情况下可以进行各种改变。另外，可将各种实现的实施方式的特征组合以形成本发明的其他实施方式。
