Description

内置双离合器的用于电力驱动汽车的牵引装置
技术领域
本发明涉及有永久磁体的同步电动机领域，具体为一种内置双离合器的用于电力驱动汽车的牵引装置。
背景技术
目前新能源电机正得到日益广泛的应用，尤其在混合动力汽车领域应用更多。新能源电机为永磁同步电机，配备有电机控制器，既能由外部机械拖动作为发电机使用以输出电能，又能够作为电动机使用从外部输入电能以驱动其他机械。永磁同步电机使用于汽车，按照在汽车上的作用不同可分为混合动力型（即Integrated Started Generator，简称ISG）、驱动型（简称TM）等类型。ISG电机和发动机连接，由发动机驱动ISG电机用于生成驱动汽车所需要的电能；TM电机为驱动电机用于驱动汽车行驶，根据整车动力传动分配的需要不同，TM电机的输出端多与变速箱串联，或通过传动轴直接驱动后桥。ISG电机和TM电机各自独立，ISG功率功率较小，而TM电机功率较大。但是，目前混合动力汽车所使用的电机，大多还处于“各自为阵”的地步，不能很好的整合以发挥综合优势，这就限制了永磁同步电机优势的发挥，也限制了混合动力汽车的发展。
对于新能源电机来说ISG与TM都能作为发电机和电动机来使用。ISG、TM串联起来后，可以有效的动力叠加，拆分开来使用又能独立发挥各自的功能。
发明内容
为了克服现有技术的缺陷，提供一种效率高、适应性强的混合动力车辆牵引装置，本发明公开了一种内置双离合器的用于电力驱动汽车的牵引装置。
本发明通过如下技术方案达到发明目的：
一种内置双离合器的用于电力驱动汽车的牵引装置，包括发动机、同步电机和变速箱，发动机的输出轴和同步电机的输入轴连接，同步电机的输出轴和变速箱的输入轴连接，其特征是：还包括一级离合器、二级离合器和蓄电池，发动机的输出轴和一级离合器的输入轴连接，一级离合器的输出轴和同步电机的输入轴连接，同步电机的输出轴和二级离合器的输入轴连接，二级离合器的输出轴和变速箱的输入轴连接，同步电机的电极分别用导线连接蓄电池的正电极和负电极。
所述的内置双离合器的用于电力驱动汽车的牵引装置，其特征是：同步电机由花键输入轴、前端盖、机壳、后端盖、电枢和飞轮盘输出轴组成，前端盖和后端盖分别盖于机壳的前端面和后端面，电枢设于前端盖、机壳和后端盖构成的空腔内，花键输入轴的一端和电枢的转子刚性连接，花键输入轴的另一端和一级离合器中离合片的内孔配合，飞轮盘输出轴的一端和电枢的转子刚性连接，飞轮盘输出轴的另一端和二级离合器中离合片的内孔配合。
所述的内置双离合器的用于电力驱动汽车的牵引装置，其特征是同步电机选用永磁同步电机。
本发明使用时，首先启动发动机并使发动机运行在高效区，同时闭合一级离合器和同步电机，发动机带动同步电机运行，同步电机处于发电机状态，同步电机输出的电能向蓄电池充电。当蓄电池电能充满后，断开一级离合器和同步电机，发动机停机，由蓄电池向同步电机提供电能，同步电机处于电动机状态，闭合二级离合器和变速箱，此时汽车处于纯电动模式运行。当汽车需要大功率输出时，此时闭合一级离合器和同步电机，也闭合二级离合器和变速箱，发动机和同步电机串联向外输出功率，此时汽车处于混合模式运行。二级离合器的闭合和断开可以灵活地实现汽车换挡的功能需要。
本发明的有益效果是：工作效率高，工作模式选择灵活，适应性强，能使汽车始终运行高效区，实现节能减排。
