本申请要求2013年12月18日提交的韩国专利申请第10-2013-0158820号的优先权，该申请的全部内容结合于此用于通过该引用的所有目的。
技术领域
本发明涉及一种混合电动车辆的传动系统。更具体而言，本发明涉及这样一种混合电动车辆的传动系统，其可以实现电动车辆(EV)模式、动力拼合模式以及超速传动(OD)模式。
背景技术
通常而言，混合车辆是有效地应用两种不同的动力源的车辆。
这样的混合电动车辆典型地使用发动机和电动机/发电机。混合电动车辆使用具有相对更好的低速扭矩特性的电动机/发电机作为低速下的主动力源，并且使用具有相对更好的高速扭矩特性的发动机作为高速下的主动力源。
由于混合电动车辆停止利用化石燃料的发动机的操作，并且在低速区域处使用电动机/发电机，所以可以改进燃料消耗并且可以减少废气。
混合电动车辆的动力传动系统分为单模式类型和多模式类型。
用于换挡控制的诸如离合器和制动器的扭矩传递装置是不必要的，但是燃料消耗由于高速区域处的效率变差而较高，并且需要额外的扭矩倍增设备来应用于根据单模式类型的大型车辆。
由于多模式类型在高速区域效率高，并且能够自发地倍增扭矩，所以多模式类型能够应用于全尺寸车辆。
因此，采用多模式类型而非单模式类型作为混合电动车辆的动力传动系统，并且多模式类型也处于持续的研究之中。
多模式类型的动力传动系统包括多个行星齿轮组、作为电动机和/或发电机操作的多个电动机/发电机、控制行星齿轮组的旋转元件的多个扭矩传递装置、以及用作电动机/发电机的动力源的电池。
多模式类型的动力传动系统根据行星齿轮组、电动机/发电机以及扭矩传递装置的连接而具有不同的操作机构。
此外，多模式类型的动力传动系统根据行星齿轮组、电动机/发电机以及扭矩传递装置的连接而具有不同的特征，例如耐用性、动力传递效率和尺寸。因此，用于混合电动车辆的动力传动系统的连接结构的设计也处于持续的研究中，以便实现没有动力损失的稳健并紧凑的动力传动系统。

具体实施方式
下面将详细说明本发明的不同实施方案，在附图中和以下的描述中示出了这些实施方案的实例。虽然本发明与示例性实施方案相结合进行描述，但是应当了解，本说明书并非旨在将本发明限制为那些示例性实施方案。相反，本发明旨在不但覆盖这些示例性实施方案，而且覆盖可以被包括在由所附权利要求所限定的本发明的精神和范围之内的各种替换、修改、等效形式以及其它实施方案。
图1为根据本发明的第一示例性实施方案的混合电动车辆的传动系统的示意图。
参考图1，根据本发明的各个实施方案的混合电动车辆的传动系统包括输入轴IS、行星齿轮组PG、第一电动机/发电机MG1和第二电动机/发电机MG2、制动器BK、为旋转限制构件的单向离合器OWC以及减速装置CGU。
输入轴IS连接到发动机ENG的输出侧并且接收发动机ENG的扭矩。
行星齿轮组PG设置在输入轴IS上并且为单小齿轮行星齿轮组。行星齿轮组PG包括作为行星齿轮组PG的旋转元件的太阳齿轮S、行星架PC以及环形齿轮R，行星架PC可旋转地支撑与太阳齿轮S外啮合的小齿轮P，环形齿轮R与小齿轮P内啮合。
太阳齿轮S为输出元件并且直接连接到第一中间输出齿轮MOG1，行星架PC直接连接到输入轴IS并且通过单向离合器OWC连接到变速器壳体H，而环形齿轮R为输出元件并且直接连接到第二中间输出齿轮MOG2。
在本说明书中描述的是，行星架PC通过单向离合器OWC连接到变速器壳体H，但是单向离合器OWC可以设置在输入轴IS和变速器壳体H之间。
第一中间输出齿轮MOG1设置在行星齿轮组的PG一侧，而第二中间输出齿轮MOG2设置在第一中间输出齿轮MOG1和行星齿轮组PG之间。
第一电动机/发电机MG1和第二电动机/发电机MG2的每一个作为电动机或发电机操作，并且设置成远离输入轴IS。
第一电动机/发电机MG1用于产生电能并且包括固定到变速器壳体H的第一定子ST1，以及在第一定子ST1中可旋转的第一转子R1。
第一转子RT1直接连接到平行于输入轴IS设置的第一电动机轴MS1。第一电动机轴MS1是空心轴，其中第一电动机轴MS1的一个端部设置有第一电动机轴齿轮MSG1，并且第一电动机轴MS1的另一个端部通过在其之间插置制动器BK而连接到变速器壳体H，第一电动机轴齿轮MSG1固定地设置在一个端部上并且与第一中间输出齿轮MOG1接合。
第二电动机/发电机MG2用于供应驱动扭矩，并且包括固定到变速器壳体H的第二定子ST2，以及在第二定子ST2中可旋转的第二转子RT2。
第二转子RT2直接连接到与输入轴IS平行设置的第二电动机轴MS2，并且第二电动机轴MS2设置在第一电动机轴MS1中，并且在第一电动机轴MS1与第二电动机轴MS2之间没有旋转干扰。
第二电动机轴齿轮MSG2固定地设置在第二电动机轴MS2的一个端部上，并且与第二中间输出齿轮MOG2接合。
此处，第一电动机/发电机MG1设置在第一电动机轴MS1的一个端部部分上，第二电动机/发电机MG2设置在第二电动机轴MS2的另一个端部上，并且制动器BK设置在第一电动机/发电机MG1和第二电动机/发电机MG2之间。
减速装置CGU包括输出轴OS以及输出轴输入齿轮OIG和输出轴输出齿轮OOG，输出轴OS与输入轴IS和第一电动机轴MS1及第二电动机轴MS2平行地设置，输出轴输入齿轮OIG和输出轴输出齿轮OOG分别固定地设置在输出轴OS的两端部部分上。
输出轴输入齿轮OIG与第二电动机轴齿轮MSG2接合，而输出轴输出齿轮OOG与差动装置DIFF的最终减速齿轮FG接合。
制动器BK可以为湿式常规多碟摩擦元件，而旋转限制构件可以为单向离合器OWC，但是并不限于此。可以使用双向离合器或制动器作为旋转限制构件。
图2为根据本发明的第一示例性实施方案的混合电动车辆的传动系统在每个模式下的操作图表。
参考图2，根据本发明的各个实施方案的混合电动车辆的传动系统可以实现电动车辆(EV)模式、动力拼合模式以及超速传动(OD)模式。
在EV模式下操作单向离合器OWC，在OD模式下操作制动器BK，而在动力拼合模式下既不操作单向离合器OWC也不操作制动器(BK)，当车辆在城市道路上行驶时经常使用动力拼合模式。
参考图3至图5，下面将详细描述在根据本发明的第一示例性实施方案的混合电动车辆的传动系统中在每个模式下的动力流。
图3为用于示出在根据本发明的各个实施方案的混合电动车辆的传动系统中在电动车辆(EV)模式下的动力流的示意图。
参考图3，在EV模式下，通过单向离合器OWC的操作而限制输入轴IS的旋转，并且发动机ENG保持在停止状态下。
在该状态下，操作第二电动机/发电机MG2，并且第二电动机/发电机MG2的扭矩通过第二电动机轴MS2、第二电动机轴齿轮MSG2、输出轴输入齿轮OIG、输出轴OS以及输出轴输出齿轮OOG而传输到差动装置DIFF的最终减速齿轮FG。
图4为用于示出在根据本发明的各个实施方案的混合电动车辆的传动系统中在动力拼合模式下的动力流的示意图。
参考图4，当车辆在城市道路上行驶时经常使用动力拼合模式，而在动力拼合模式下不操作制动器BK和单向离合器OWC。
在动力拼合模式下，操作发动机ENG和第二电动机/发电机MG2，并且发动机ENG和第二电动机/发电机MG2的扭矩被传输到差动装置DIFF的最终减速齿轮FG。
也即，发动机ENG的扭矩通过输入轴IS输入到行星齿轮组PG的行星架PC中，通过环形齿轮R传输到第二中间输出齿轮MOG2作为主动力，并且通过太阳齿轮S传输到第一中间输出齿轮MOG1。
传输到第二中间输出齿轮MOG2的扭矩在第二电动机轴齿轮MSG2处与第二电动机/发电机MG2的扭矩相加，并且经相加的扭矩通过输出轴输入齿轮OIG、输出轴OS以及输出轴输出齿轮OOG而传输到差动装置DIFF的最终减速齿轮FG。
传输到第一中间输出齿轮MOG1的扭矩通过第一电动机轴齿轮MSG1和第一电动机轴MS1而传输到第一转子RT1，并且使得第一电动机/发电机MG1产生电能。由第一电动机/发电机MG1产生的电能用于为电池充电或供应到第二电动机/发电机MG2。
图5为用于示出在根据本发明的第一示例性实施方案的混合电动车辆的传动系统中在OD模式下的动力流的示意图。
参考图5，在OD模式下操作制动器BK。
在OD模式下，发动机ENG的扭矩用作主动力，而第二电动机/发电机MG2的扭矩用作辅助动力。
也即，如果发动机ENG的扭矩通过输入轴IS输入到行星齿轮组PG的行星架PC，则太阳齿轮S通过制动器BK的操作而操作作为固定元件。因此，通过环形齿轮R输出具有增加的旋转速度的扭矩。具有增加的旋转速度的扭矩通过第二中间输出齿轮MOG2而传输到第二电动机轴齿轮MSG2，并且在第二电动机轴齿轮MSG2处与第二电动机/发电机MG2的扭矩相加。因此，经相加的扭矩通过输出轴输入齿轮OIG、输出轴OS以及输出轴输出齿轮OOG而传输到差动装置DIFF的最终减速齿轮FG。
通过结合两个电动机/发电机MG1和MG2、制动器BK以及单向离合器OWC，根据本发明的各个实施方案的混合电动车辆的传动系统可以实现EV模式、动力拼合模式以及OD模式。
由于液压在当车辆在城市道路上行驶时经常使用的动力拼合模式下不提供到制动器BK，因此可以提高燃料经济性。
由于通过使用行星齿轮组PG而实现OD模式，因此可以提高燃料经济性并且可以减少第一电动机/发电机MG1的容量。
由于通过使用行星齿轮组PG而实现OD模式，因此可以移除用于实现OD模式的输出齿轮组并且可以缩短变速器的长度。
图6为用于示出在根据本发明的各个实施方案的混合电动车辆的传动系统中在发动机直接联接模式下的动力流的示意图。
参考图6，本发明的各个实施方案进一步包括用于直接联接行星齿轮组PG的离合器CL。
也即，离合器CL连接行星齿轮组PG的三个旋转元件之中的两个旋转元件并且直接联接行星齿轮组PG。离合器CL设置在行星架PC和环形齿轮R之间。
如果操作离合器CL，则行星齿轮组PG成为直接联接状态并且可以实现发动机直接联接模式。
通过结合两个电动机/发电机、制动器以及旋转限制构件，根据本发明的各个实施方案的混合电动车辆的传动系统可以实现EV模式、动力拼合模式以及OD模式。
由于液压在当车辆在城市道路上行驶时经常使用的动力拼合模式下不提供到制动器，因此可以提高燃料经济性。
由于实现了OD模式，因此可以通过减少机械动力损失而提高燃料经济性并且可以减少第一电动机/发电机的容量。
由于输入轴的旋转速度通过在输入轴上的行星齿轮组而得以增加并且之后被供应到电动机/发电机，因此可以减少电动机/发电机的容量并且可以缩短变速器的长度。
前面对本发明具体示例性实施方案所呈现的描述是出于说明和描述的目的。前面的描述并不想要成为毫无遗漏的，也不是想要把本发明限制为所公开的精确形式，显然，根据上述教导很多改变和变化都是可能的。选择示例性实施方案并进行描述是为了解释本发明的特定原理及其实际应用，从而使得本领域的其它技术人员能够实现并利用本发明的各种示例性实施方案及其不同选择形式和修改形式。本发明的范围意在由所附权利要求书及其等价形式所限定。
