Description

多模式混合可变驱动单元
技术领域
本公开涉及混合驱动单元，更具体地，涉及多模式混合可变驱动单元。
背景技术
很多现代汽车都使用混合传动***，在该混合传动***中，内燃发动机、电机或二者的组合为车辆提供推进力。在典型的混合传动***中，来自发动机和电机的转矩供给到多个齿轮，以驱动车辆的车轮。很多典型的混合传动装置仅提供单个运行模式。此单个运行模式造成了整个***的折中。必须在在低速运行期间提供最佳转矩的传动或为在高速下运行提供最佳效率的传动装置之间作出决定。很多典型的混合传动装置不能够同时提供最佳低速转矩和最佳高速效率。典型地，在尝试纠正此问题时，必须使用大型的大功率电机。然而，大型的大功率电机较昂贵且在混合传动装置内占据更多的空间。
可替换地，一些混合传动装置提供多个运行模式，借此可以实现不同的传动齿轮比。然而，典型的现有技术的多模式混合传动装置包括很多齿轮和离合器，并且非常低效。例如，很多现有技术的混合传动装置以必须一直旋转的多个行星齿轮组为特征。这对车辆的燃料经济性有负面影响。此外，很多现有技术的混合传动装置是复杂的且尺寸较大。这增加了制造成本并且使得将混合传动装置装配在车辆内较困难。因此，期望本领域中的改进。

附图说明
图1是根据所公开的原理构造的示例性混合驱动单元的示意性图示；以及
图2是根据所公开的原理构造的另一个示例性混合驱动单元的示意性图示。
具体实施方式
图1是对根据本文所公开的实施方式的混合驱动单元10的示范性的示意性图示。发动机1联接到扭振减震器2。发动机1可以是任何类型的动力源，包括内燃发动机、涡轮发动机、电机或任何其他期望的动力源。扭振减震器2通过混合输入轴6联接到混合驱动单元10。混合输入轴6将扭振减震器2联接到第一行星齿轮组20的托架24。多个行星齿轮22旋转地安装在托架24上，并且与太阳齿轮21和环形齿轮23连续地啮合。太阳齿轮21通过轴41联接到第一电机11(“EMA”)。环形齿轮23通过轴7联接到第二电机12(“EMB”)。第一电机11和第二电机12可以为电马达、发电机或任何其他类型的期望的动力源。
轴41还联接到第二离合器机构52，该第二离合器机构52将轴41选择性地联接到第二行星齿轮组30的托架34。多个行星齿轮32旋转地安装在托架34上并且与太阳齿轮31和环形齿轮33连续地啮合。环形齿轮33还联接到第三离合器机构53。第三离合器机构53将环形齿轮33选择性地联接到混合组件壳体16。太阳齿轮31联接到轴7。托架34还联接到第一驱动齿轮35，该第一驱动齿轮35与第一从动齿轮36连续地啮合。第一从动齿轮36通过轴8联接到第二驱动齿轮37。第二驱动齿轮37与联接到输出轴9的第二从动齿轮38连续地啮合。轴7还联接到第一离合器机构51，该第一离合器机构51将轴7选择性地联接到第二从动齿轮38。
图1的混合驱动单元10可以在三种不同的模式中运行，该三种不同的模式在本文中称为模式1、模式2和模式3。为使混合驱动单元10在模式1中运行，启动第三离合器机构53，从而将环形齿轮33联接到混合组件壳体16。停用第一离合器机构51和第二离合器机构52。由此，轴7以与第二从动齿轮38不同的每分钟转数(RPM)自由地旋转，并且轴41以与托架34不同的每分钟转数自由地旋转。输出到输出轴9的扭矩可以由发动机1结合第二电机12提供。第一电机11可以用于在车辆刹车期间或根据其他需要而生成电力。在一个实施方式中，当在模式1中运行时，混合驱动单元10实现大致4.5:1的混合驱动单元齿轮比。
为了将混合驱动单元10从在模式1中运行转变到在模式2中运行，为第一电机11供电，以使轴41的每分钟转数与托架34的每分钟转数大致匹配。在一个实施方式中，可使用发动机1、第二电机12、第一电机11或三者的任何组合来使轴41的每分钟转数与托架34的每分钟转数大致匹配。一旦轴41的每分钟转数与托架34的每分钟转数大致匹配，则启动第二离合器机构52，随后停用第三离合器机构53。在一个实施方式中，换档过程包括启动第二离合器机构52和停用第三离合器机构53，并且占用大致500毫秒的时间。在一个实施方式中，换档占用多于500毫秒的时间。在另一个实施方式中，换档占用少于500毫秒的时间。从模式2到模式1的换档会以类似于从模式1到模式2的换档的方式进行，除了会使用发动机1、第二电机12、第一电机11中的一个或其任何组合，以使环形齿轮33的每分钟转数与混合组件壳体16的每分钟转数大致相同。然后，会启动第一离合器机构51，随后停用第二离合器机构52。
为使混合驱动单元10在模式2中运行，启动第二离合器机构52，从而将轴41联接到托架34。停用第一离合器机构51和第三离合器机构53。由此，轴7以与第二从动齿轮38不同的每分钟转数自由地旋转，并且环形齿轮33以与混合组件壳体16不同的每分钟转数自由地旋转。输出到输出轴9的扭矩可以由发动机1结合第一电机11提供。第二电机12可以用于在车辆刹车期间或根据其他需要而生成电力。当混合驱动单元10在模式2中运行时，第二行星齿轮组30被锁定，从而卸载。锁定第二行星齿轮组30及使其卸载减少了混合驱动单元10内的摩擦损失。在一个实施方式中，当在模式2中运行时，混合驱动单元10实现在大致4.5:1与1:1之间的混合驱动单元齿轮比。
为了将混合驱动单元10从在模式2中运行转变到在模式3中运行，为发动机1和第二电机12供电，以使轴7的每分钟转数与第二从动齿轮38的每分钟转数大致匹配。同时，使第一电机11以大致恒定的每分钟转数运行。一旦轴7的每分钟转数与第二从动齿轮38的每分钟转数大致匹配，则启动第一离合器机构51。在一个实施方式中，换档过程包括启动第一离合器机构51，并且占用大致500毫秒的时间。在一个实施方式中，换档占用多于500毫秒的时间。在另一个实施方式中，换档占用少于500毫秒的时间。从模式3到模式2的换档会通过简单地停用第一离合器机构51而进行。
为使混合驱动单元10在模式3中运行，启动第一离合器机构51和第二离合器机构52。由此，使轴7联接到第二从动齿轮38并且使轴41联接到托架34。停用第三离合器机构53，从而允许环形齿轮33以与混合组件壳体16不同的每分钟转数旋转。输出到输出轴9的扭矩可以由发动机1结合第二电机12提供。第一电机11可以用于在车辆刹车期间或根据其他需要而生成电力。在一个实施方式中，当在模式3中运行时，混合驱动单元10实现大致1:1的混合驱动单元齿轮比。
图2图示根据本文所公开的另一个实施方式的混合驱动单元210的示例。发动机201联接到扭振减震器202。发动机201可以是任何类型的动力源，包括内燃发动机、涡轮发动机、电机或任何其他期望的动力源。扭振减震器202通过混合输入轴206联接到混合驱动单元210。混合输入轴206将扭振减震器202联接到第一行星齿轮组220的托架224。多个行星齿轮222旋转地安装在托架224上，并且与太阳齿轮221和环形齿轮223连续地啮合。太阳齿轮221通过轴207联接到第一电机211(“EMA”)。环形齿轮223联接到第二电机212(“EMB”)。第一电机211和第二电机212可以为电马达、发电机或任何其他类型的期望的动力源。
轴207还联接到第二离合器机构252，该第二离合器机构252将轴207选择性地联接到第一驱动齿轮239。第一驱动齿轮239通过链条驱动件260联接到第一从动齿轮240。链条驱动件260可以是链条、皮带或任何其他适当的链接件。第一从动齿轮240通过轴242联接到第二行星齿轮组230的环形齿轮233。环形齿轮与旋转地安装在托架234上的多个行星齿轮232连续地啮合。多个行星齿轮232与太阳齿轮231连续地啮合。太阳齿轮231通过轴208联接到第二从动齿轮236。第一离合器机构251将轴242选择性地联接到混合组件壳体216。第三离合器机构253将轴242选择性地联接到轴208，从而联接到太阳齿轮231。
第二从动齿轮236与通过轴241联接到第一电机212和环形齿轮223的第二驱动齿轮235连续地啮合。托架234通过轴244联接到输出驱动齿轮237，该输出驱动齿轮237与输出从动齿轮238连续地啮合。在一个实施方式中，输出从动齿轮238可以直接地或以其他方式连接到车辆的车轮(未示出)。
图2的混合驱动单元210可以在两种不同的模式：模式1和模式2中运行。为使混合驱动单元210在模式1中运行，启动第一离合器机构251，从而将轴242联接到混合组件壳体216。停用第二离合器机构252和第三离合器机构253。由此，轴207以与第一驱动齿轮239不同的每分钟转数自由地旋转，并且轴242以与太阳齿轮231不同的每分钟转数自由地旋转。因为第一离合器机构251启动，所以第二行星齿轮组230被有效地锁定，从而卸载。锁定第二行星齿轮组230及使其卸载减少了混合驱动单元210内的摩擦损失。输出到输出从动齿轮238的扭矩可以由发动机201结合第二电机212提供。第一电机211可以用于在车辆刹车期间或根据其他需要而生成电力。
为将混合驱动单元210从在模式1中运行转变到在模式2中运行，启动第二离合器机构252。一旦第二离合器机构252完全启动，停用第一离合器机构251。在此转变期间，第一电机211用于提供扭矩，并且第二电机212用于生成电力。发动机201、第一电机211、第二电机212或三者的任何组合用于使轴242的每分钟转数与太阳齿轮231的每分钟转数大致相同。一旦轴242的每分钟转数与太阳齿轮231的每分钟转数大致相同，则启动第三离合器机构252，随后停用第二离合器机构252。在一个实施方式中，换档过程包括启动第二离合器机构252、停用第一离合器机构251、启动第三离合器机构253、停用第二离合器机构252并且占用大致500毫秒的时间。在一个实施方式中，换档占用多于500毫秒的时间。在另一个实施方式中，换档占用少于500毫秒的时间。
从模式2到模式1的换档会以类似的方式进行，除了会使用发动机201、第二电机212、第一电机211中的一个或其任何组合，以使轴207的每分钟转数与第一驱动齿轮239的每分钟转数大致相同以外。然后，会启动第二离合器机构252，随后停用第三离合器机构253。接下来，会启动第一离合器机构251，随后停用第二离合器机构252。
为使混合驱动单元210在模式2中运行，启动第三离合器机构253，将轴242联接到太阳齿轮231。停用第一离合器机构251和第二离合器机构252。由此，轴242以与混合组件壳体216不同的每分钟转数自由地旋转，并且轴207以与第一驱动齿轮239不同的每分钟转数自由地旋转。输出到输出从动齿轮238的扭矩可以由发动机201结合第二电机212提供。第一电机211可以用于在车辆刹车期间或根据其他需要而生成电力。
在一个实施方式中，第一离合器机构51、第二离合器机构52和第三离合器机构53可以为任何期望类型的联接装置，包括湿式离合器、干式离合器、爪式离合器或多片式离合器。在一个实施方式中，当两个部件在彼此的预定每分钟转数内旋转时，离合器机构51、52、53可以将该两个部件联接在一起。例如，一旦两个部件在彼此的大致50的每分钟转数内旋转时，离合器机构51、52、53可以将该两个部件联接在一起。在另一个实施方式中，一旦两个部件在彼此的大于或小于50的每分钟转数内旋转时，离合器51、52、53可以将两个部件联接在一起。作为一个示例，湿式离合器、干式离合器或多片式离合器可以用于将在彼此的大致50的每分钟转数内旋转的两个部件联接在一起。在另一个实施方式中，只有在两个部件以大致相同的每分钟转数旋转时，离合器机构51、52、53才可将两个部件联接在一起。作为一个示例，爪式离合器可以用于将以大致相同的每分钟转数旋转的两个部件联接在一起。
由此，本文公开了在紧凑装置中提供多个运行模式的混合传动装置。此外，该混合传动装置包括较小的或较紧凑的电机。因为混合传动装置使用较少的零件，因而其还以比现有技术设计更简单的构造为特征。。
