技术领域
本发明涉及无级变速混合动力汽车，具体涉及一种无级变速混合动力汽车动力成。
背景技术
混合动力汽车是为适应节能减排发展趋势的一种汽车，能够实现无级变速的无级变速混合动力汽车动力系统不仅满足节能减排这一要求，而且换挡过程平顺无冲击、工作效率较高。目前，常见的一种无级变速混合动力汽车动力总成，包括发动机、驱动电机和第一行星排，能够实现无级变速,所存在的问题是；仅仅通过一个行星排实现变速，其传动比较小，发动机不能常在高效区域工作，同时驱动电机工作效率低下、易高温发热、成本较高；在驱动发电模式下，没有发电功能，汽车行驶里程较短。
发明内容
本发明要解决的技术问题是提供一种无级变速混合动力汽车动力总成，其传动比较大，能够使发动机常在高效区域工作，同时驱动电机工作效率较高、避免高温发热、成本较低，效率较高，且在驱动发电模式下，具有发电功能，使汽车行驶里程较长。

在本发明中，优选离合器3为干式离合器。
在本发明中，优选发动机1为阿特森发动机。
本发明工作原理如下：
纯电模式；发动机1不工作，ISG电机17不工作，驱动电机4工作，离合器3断开，制动器16制动。驱动电机4通过驱动电机4的电机转子41将动力传递给外圈5后，其动力分两条路径进行传递，第一条动力由外圈5传递给第二行星排的第二齿圈14；第二条动力由外圈5传递给第一行星排的第一齿圈9，在制动器16将连接轴10、第一行星排的第一太阳轮6制动的情况下，动力由第一行星排的第一行星架8传递给第二行星排的第二太阳轮11，两条动力分别传给第二行星排的第二太阳轮11和第二齿圈14并在第二行星排上进行耦合，最终由第二行星排的第二行星架13传递给输出轴15。
混动模式；发动机1工作，ISG电机17不工作，驱动电机4工作，离合器3结合，制动器16松开。发动机1通过曲轴2将动力依次传递给离合器3、连接轴10、第一行星排的第一太阳轮6，驱动电机4通过其电机转子41将动力传递给外圈5后，其动力分别传递给第一行星排的第一齿圈9和第二行星排的第二齿圈14，发动机1和驱动电机4的动力传给第一行星排和第二行星排后进行耦合，最终由第二行星排的第二行星架13传递给输出轴15。
能量回收；发动机1不工作，ISG电机17不工作，驱动电机4处于发电状态，离合器3断开，制动器16制动。整车动力由车轮传递到输出轴15后，在制动器16将连接轴10、第一行星排的第一太阳轮6制动的情况下，动力在第一行星排和第二行星排上进行耦合，然后分别通过第一行星排的第一齿圈9和第二行星排的第二齿圈14共同传递给外圈5，最后传递给驱动电机1的电机转子41，并由电机转子41带动处于发电状态的驱动电机1发电。
驱动发电模式；发动机1工作并带动ISG电机17处于发电状态，驱动电机4工作，离合器3断开，制动器16制动。在制动器16将连接轴10、第一行星排的第一太阳轮6制动的情况下，驱动电机4通过其电机转子41将动力传递给外圈5后，其动力分别传递给第一行星排的第一齿圈9和第二行星排的第二齿圈14，由第一行星排和第二行星排进行耦合并通过第二行星排的第二行星架13传递给输出轴15。在驱动电机1驱动汽车运行的同时发动机1将动力传递给处于发电状态的ISG电机17进行发电。
启动发动机模式；发动机1待启动，ISG电机17工作，驱动电机4不工作，离合器3断开，制动器16松开。ISG电机17通过其ISG电机转子171将动力通过曲轴2传递给发动机1，启动发动机1。
上面结合附图对本发明的优选实施方式做了详细说明，但是本发明并不限于上述实施方式，在所属技术领域普通技术人员所具备的知识范围内，还可以在不脱离本发明宗旨的前提下作出各种变化。
