在这些附图中，在贯穿附图的多幅图形中，附图标记指代本发明的相同的或等效的部分。
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。
下面将参考附图对本发明的优选实施方案进行详细描述。
参照图1，根据本发明的示例性实施方案的用于车辆的混合动力系包括：输入轴IN、发动机侧驱动齿轮1、输出轴OUT、发动机侧从动齿轮3、电动机侧驱动齿轮5、电动机侧从动齿轮7、输出齿轮9、单向离合器25、离合器单元CL以及行星齿轮机构PG，其中，安装输入轴IN以接收发动机E的动力；发动机侧驱动齿轮1设置在输入轴IN上；输出轴OUT设置为平行于输入轴IN；所述发动机侧从动齿轮3可旋转地布置在输出轴OUT处以便与发动机侧驱动齿轮1啮合；电动机侧驱动齿轮5安装为与输入轴IN同轴并且通过电动机M旋转；电动机侧从动齿轮7固定地设置在输出轴OUT处以便与电动机侧驱动齿轮5啮合；输出齿轮9旋转地设置在输出轴OUT上；单向离合器25安装在输出齿轮9和输出轴OUT之间，以当车辆向前行驶时，仅在从输出轴OUT至输出齿轮9的方向上传递动力；设置离合器单元CL以便相对于输出轴OUT在固定状态和释放状态之间转换输出齿轮9的运行状态，并且以便相对于输出轴OUT在固定状态和释放状态之间转换发动机侧从动齿轮3的运行状态；安装行星齿轮机构PG以将输出轴OUT和输出齿轮9彼此相联接。
换言之，已通过输入轴IN从发动机E传递至输出轴OUT的发动机动力和已从电动机M传递至输出轴OUT的电动机动力通过输出齿轮9从输出轴OUT输出至正被驱动的机构。在此，单向离合器25和行星齿轮机构PG都设置在输出轴OUT和输出齿轮9之间，从而输出轴OUT的动力能够通过两个挡位中的任意一个而输出至输出齿轮9，因此本发明的混合齿轮系能够在每个驱动模式中形成两个挡位。因此，本发明可以使用简单的构造而使在每个驱动模式中的多个挡位成为可能，并且根据车辆的不同的行驶环境，通过优化利用各自驱动模式的多个挡位而能够有效地驱动车辆，所以本发明能够提高车辆的驱动效率并且能够增加车辆的里程。
在行星齿轮机构PG中，行星架C直接连接至输出轴OUT，内齿圈R直接连接至输出齿轮9，安装太阳轮S使得太阳轮S与输出轴OUT同轴并且可选择地固定至静止构件，并且设置制动器BK以可选择地将太阳轮S固定。
相应地，当车辆在制动器BK被释放的状态下向前行驶时，形成第一挡位，其中输出轴OUT的动力通过单向离合器25输出至输出齿轮9。但是，当车辆在制动器BK被接合的状态下向前行驶时，输出轴OUT的动力传递至行星架C，并且在输出至输出齿轮9之前通过内齿圈R增加动力的速度。当然，在这种情况下，单向离合器25允许输出齿轮9在比输出轴OUT的速度更高的速度下旋转。
离合器单元CL包括第一犬齿式离合器CL-D1以及第二犬齿式离合器CL-D2，第一犬齿式离合器CL-D1能够在固定状态(其中输出齿轮9固定至输出轴OUT)和释放状态(其中输出齿轮9从输出轴OUT释放)之间转换输出齿轮9的运行状态，第二犬齿式离合器CL-D2能够在固定状态(其中发动机侧从动齿轮3固定至输出轴OUT)和释放状态(其中发动机侧从动齿轮3从输出轴OUT上释放)之间转换发动机侧从动齿轮3的运行状态。
在此，通过离合器单元的第一犬齿式离合器CL-D1将输出齿轮9固定至输出轴OUT的固定状态需要形成倒车挡位，其中已由电动机M输出的倒车驱动动力从输出轴OUT传递至输出齿轮9，而不考虑齿轮系中单向离合器25的存在。
离合器单元的第二犬齿式离合器CL-D2用于将发动机侧从动齿轮3连接至输出轴OUT，以便将发动机动力传递至输出轴OUT。例如，在以仅使用电动机M的动力的EV模式来驱动车辆时，当需要将发动机动力传递至输出轴OUT时，在发动机E发动并且通过控制发动机和发电机G两者的运行将输出轴OUT和输出侧从动齿轮之间的相对速度最小化之后，使第二犬齿式离合器CL-D2进入到接合状态(本文中下面将会描述)，所以发动机动力能够传递至输出轴OUT。
在本发明的示例性实施方案中，离合器单元CL可以包括第一犬齿式离合器CL-D1以及同步啮合装置，其中，第一犬齿式离合器CL-D1能够在固定状态(其中输出齿轮9固定至输出轴OUT)和释放状态(其中输出齿轮9从输出轴OUT释放)之间转换输出齿轮9的运行状态，同步啮合装置能够在固定状态(其中发动机侧从动齿轮3固定至输出轴OUT)和释放状态(其中发动机侧从动齿轮3从输出轴OUT释放)之间转换发动机侧从动齿轮3的运行状态。
在另一种情况下，当需要如上所述将发动机侧从动齿轮3连接至输出轴OUT时，甚至当发动机侧从动齿轮3和输出轴OUT之间的速度差很高时，同步啮合装置也能够相比于第二犬齿式离合器CL-D2更加有效地将发动机侧从动齿轮3连接至输出轴OUT。
在本发明的混合齿轮系中，发动机侧驱动齿轮1的直径设计成大于发动机侧从动齿轮3的直径，并且电动机侧驱动齿轮5的直径设计成小于电动机侧从动齿轮7的直径。因此，当通过发动机E的动力驱动车辆时，发动机动力能够在超速状态下传递到驱动轮，从而车辆的高速行驶模式可以主要通过发动机动力来实现。然而，当通过电动机M的动力驱动车辆时，在通过降低电动机动力的速度而提高发动机扭矩之后才输出电动机动力，因此车辆低速行驶模式可以主要通过电动机M的动力来实现。因此，本发明的混合齿轮系能够有效并且互补地利用发动机扭矩特性和电动机扭矩特性，并且能够增加车辆的里程。
在本发明的示例性实施方案中，输入轴IN直接连接至发动机E，因此，当发动机E发动时，离合器单元CL将发动机侧从动齿轮3从输出轴OUT分开，从而将发动机侧从动齿轮3从输出轴OUT释放。
另外，本实施方案的混合齿轮系进一步包括发电驱动齿轮15、发电从动齿轮17以及空转轴23，其中，发电驱动齿轮15设置在输入轴IN上；发电从动齿轮17可旋转地安装在输入轴IN上以便与输入轴IN同轴并且旋转发电机G；空转轴23布置为平行于输入轴IN，并且具有与发电驱动齿轮15相啮合的第一中间齿轮19和与发电从动齿轮17相啮合的第二中间齿轮21，因此混合齿轮系能够通过使用发动机动力的发电机G而连续地产生电力。
发电机G产生的电力能够储存在电池中，并且储存在电池中的电力能够供应至电动机M。
图2和图3示出本发明发动机模式中的不同的挡位，其中通过释放制动器BK并且通过使用离合器单元CL将发动机侧从动齿轮3连接至输出轴OUT来实现图2中的发动机模式的第一挡位。
在发动机模式中的第一挡位中，发动机E的动力通过发动机侧驱动齿轮1、发动机侧从动齿轮3和离合器单元CL从输入轴IN传递至输出轴OUT，并且输出轴OUT的动力通过单向离合器25传递至输出齿轮9，从而用于实现发动机模式中的第一挡位的驱动动力能够从输出齿轮9输出至被驱动的机构。
图3显示了发动机模式中的第二挡位，其能够通过在发动机模式的第一挡位中，使制动器BK进入接合状态而实现。在发动机模式中的第二挡位中，行星齿轮机构PG提高输出轴OUT的动力的速度，并且通过输出轴OUT的动力驱动输出齿轮9。在上述的状态中，输出齿轮9以高于输出轴OUT的速度的速度旋转，并且单向离合器25允许输出齿轮9在比输出轴OUT更高的速度下旋转。
图4和图5示出了EV模式中的不同的挡位，其中图4示出了EV模式中第一挡位。在EV模式中的第一挡位中，电动机动力通过电动机侧驱动齿轮5和电动机侧从动齿轮7传递至输出轴OUT，并且输出轴OUT的动力通过单向离合器25输出至输出齿轮9。
图5示出了EV模式中的第二挡位。在EV模式中第二挡位中，制动器BK将太阳轮S固定，并且已从电动机M传递至输出轴OUT的电动机动力的速度通过行星齿轮机构PG而增加，并且输出轴OUT的动力输出至输出齿轮9。
图6和图7示出了混合模式之一的并行模式中的不同的挡位，其中图6示出了并行模式中的第一挡位。在并行模式的第一挡位中，发动机E和电动机M都运行，并且在输出轴OUT将发动机动力和电动机动力结合在一起，而且经结合的动力通过单向离合器25从输出轴OUT输出至输出齿轮9。
当然，在上述状态下，离合器单元CL将发动机侧从动齿轮3连接至输出轴OUT。
图7示出了并行模式中第二挡位。在图6的并行模式中的第一挡位中，可以通过使制动器BK进入接合状态而实现并行模式中的第二挡位。在并行模式中的第二挡位中，通过将发动机动力和电动机动力在输出轴OUT处结合在一起而形成的经结合的动力，在经过行星架C和内齿圈R时提高经结合的动力的速度之后，输出至输出齿轮9。
图8和图9示出了混合模式之一的串行模式中不同的挡位，其中
图8示出了串行模式中第一挡位。在串行模式中的第一挡位中，发电机G由发动机动力驱动并产生电力。将电力供应至电池以便储存在其中，并且电池的电力供应至电动机，因此电动机能够运行并且能够输出电动机动力。电动机动力传递至输出轴OUT，并且通过单向离合器25输出至输出齿轮9。
在串行模式中的第一挡位中，离合器单元CL从输出轴OUT释放发动机侧从动齿轮3，从而防止发动机动力传递至输出轴OUT。
图9示出了串行模式中的第二挡位。在图8的串行模式中的第一挡位中，可以通过使制动器BK进入接合状态而实现串行模式中的第二挡位。在串行模式中的第二挡位中，在电动机动力从输出轴OUT输出至输出齿轮9之前，通过行星齿轮机构PG提高已传递至输出轴OUT的电动机动力的速度。
作为参考，图2至图9的粗线表示用于发动机动力和电动机动力的传递线。
