下面将参考附图并结合实施例来详细说明本公开。
本实施例涉及一种双电机混合动力系统，如图1所示的，其包括有发动机1、发电机3、驱动电机2、差速器18以及输入轴10和输出轴11，且其中， 发动机1通过离合器6传动连接输入轴10，差速器18则与输出轴11传动相连。
此外，在输入轴10上则设置有可控通断的多个发动机主动齿轮，在输出轴11上设置有可控通断的多个从动齿轮，在驱动电机2的输出端也设置有多个驱动电机主动齿轮。而上述的发动机主动齿轮、从动齿轮和驱动电机主动齿轮的数量相同，并被配置为并排布置的多列，并且各列中的发动机主动齿轮和驱动电机主动齿轮分别啮合连接于从动齿轮的两侧。
本实施例中，作为一种优选的示例性实施形式，仍参考图1中所示的，上述的发动机主动齿轮包括有设于输入轴10上的发动机一挡主动齿轮7和发动机二挡主动齿轮9，并且在输入轴10上也设置有用于可控导通发动机一挡主动齿轮7或发动机二挡主动齿轮9的第一同步器单元。而在具体实施时，该第一同步器单元则优选地可为采用位于发动机一挡主动齿轮7和发动机二挡主动齿轮9之间的第一同步器8。
此时，在第一同步器8的作用下，便可使得发动机一挡主动齿轮7和发动机二挡主动齿轮9择一与输入轴10联接，以被输入轴10所带动。
与上述发动机主动齿轮的构成类似的，本实施例的从动齿轮具体包括设置于输出轴11上的一挡从动齿轮12和二挡从动齿轮14，并且在输出轴11上亦设置有用于可控导通一挡从动齿轮12或二挡从动齿轮14的第二同步器单元。而第二同步器单元则优选可采用位于一挡从动齿轮12和二挡从动齿轮14之间的第二同步器13。
此时，在第二同步器13的作用下，也可使得一挡从动齿轮12和二挡从动齿轮14择一与输出轴11联接，以能够带动输出轴11转动。
本实施例的驱动电机主动齿轮则具体包括驱动电机一挡主动齿轮16和驱 动电机二挡主动齿轮17。与此同时，以上的发动机一挡主动齿轮7、一挡从动齿轮12和驱动电机一挡主动齿轮16布置成一列，而发动机二挡主动齿轮9、二挡从动齿轮14和驱动电机二挡主动齿轮17则布置成另一列。
本实施例中，发电机3和发动机1之间传动相连，且作为一种优选实施形式，发动机1和发电机3也具体通过啮合相连的第一传动齿轮19与发电机传动齿轮4传动相连。而同样作为优选实施形式，在发动机1和离合器2之间也设置有扭转减震器5，在输出轴11上设置有驻车齿轮15，并且输出轴11和差速器18之间也为通过啮合相连的输出齿轮21和第二传动齿轮20实现传动相连。
另外，本实施例中，特别的，发电机3和驱动电机2之间也设置为使得该两者的转轴平行布置。如此，结合于图1中所示，通过发电机3与驱动电机2转轴的平行，便可大大减小整套系统的尺寸，有利于降低系统体积，且也能够使得系统有着更好的兼容性。
本实施例的双电机混合动力系统，通过发动机1、发电机3、驱动电机2，以及输入轴10上的多个发动机主动齿轮，输出轴11上的多个从动齿轮，和驱动电机2输出端上的多个驱动电机主动齿轮的设置，并通过各列中的发动机主动齿轮和驱动电机主动齿轮分别与从动齿轮的啮合连接，由此通过控制不同发动机主动齿轮及从动齿轮的通断，即能够实现系统多模式及多挡位驱动。
而基于此，本实施例的双电机混合动力系统可实现的驱动挡位及驱动模式包括有：
(1)纯电驱动一挡
此时，如图2中所示，在纯电驱动一挡中，驱动电机2上电，离合器6断开，第一同步器8处于空挡位置，第二同步器13与一挡从动齿轮12啮合。 动力由驱动电机2经驱动电机一挡主动齿轮16传输到输出轴11上，输出轴11再通过输出齿轮21和第二传动齿轮20将动力传输到差速器18，差速器18连接驱动轴，最终将动力传输至车轮。

(6)发动机驱动四挡
此时，如图7中所示，发动机1启动，离合器6结合，第一同步器8与发动机一挡主动齿轮9啮合，第二同步器13与二挡从动齿轮14啮合。动力由发动机1经发动机二挡主动齿轮9、二挡从动齿轮14将动力传输到输出轴11上，输出轴11再通过输出齿轮21和第二传动齿轮20将动力传输到差速器18，差速器18连接驱动轴，最终将动力传输至车轮。
(7)能量回收模式一
此时，如图8中所示，当车辆减速时，第二同步器13与二挡从动齿轮14啮合，车轮的动能通过驱动轴传递到差速器18，差速器18再通过第二传动齿轮20和输出齿轮21传递到输出轴11，并最后通过驱动电机二挡主动齿轮17传递到驱动电机2，以进行发电，将能量回收到动力电池。
(8)能量回收模式二
此时，如图9中所示，当车辆减速时，第二同步器13与一挡从动齿轮12啮合，车轮的动能通过驱动轴传递到差速器18，在由差速器18通过第二传动齿轮20和输出齿轮21传递到输出轴11，并再通过驱动电机一挡主动齿轮16传递到驱动电机2，以进行发电，将能量回收到动力电池。
(9)充电模式
此时，如图10中所示，离合器6断开，发动机1运行带动发电机3发电，为动力电池提供充电。
(10)增程模式一
此时，如图11中所示，驱动电机2上电，离合器6断开，发动机1运行带动发电机3发电，而为驱动电机2提供电能，同时，驱动电机2进入纯电一挡驱动，实现增程模式。
(11)增程模式二
此时，如图12中所示，驱动电机2上电，离合器6断开，发动机1运行带动发电机3发电，而为驱动电机2提供电能，同时，驱动电机2进入纯电二挡驱动，实现增程模式。

(13)混合驱动模式二
此时，如图14中所示，发动机1进入发动机二挡驱动模式，同时，驱动电机2上电输出动力，发动机1输出动力与驱动电机2输出动力在驱动电机2的输出端完成耦合，动力再通过驱动电机一挡主动齿轮16传输到输出轴11，并再传输至差速器18，进而传输至车轮。
(14)混合驱动模式三
此时，如图15中所示，发动机1进入发动机三挡驱动模式，同时，驱动 电机2上电输出动力，发动机1输出动力与驱动电机2输出动力在驱动电机2的输出端完成耦合，动力再通过驱动电机二挡主动齿轮17传输到输出轴11，并再传输至差速器18，进而传输至车轮。
(15)混合驱动模式四
此时，如图16中所示，发动机1进入发动机四挡驱动模式，同时，驱动电机2上电输出动力，其动力通过驱动电机二挡主动齿轮17传输到输出轴11，发动机1输出动力与驱动电机2输出动力在输出轴11上完成耦合，并传输至差速器18，进而传输至车轮。
由以上各驱动挡位及驱动模式可以看出，本实施例的双电机混合动力系统能够实现发动机直驱4个档位，纯电驱动2个档位，以及混合驱动多个档位的驱动，同时，也能够实现纯电驱动、发动机直接驱动、增程驱动、多种混合驱动、能量回收和怠速发电等多种驱动模式。
而且本实施例的发动机1和驱动电机2通过多档位调节输出动力，也可使发动机1始终保持在高效区，以能够降低整车油耗。
此外，还需要注意的是，在前述的四种混合驱动模式下，本实施例通过加入发电机3驱动，以及由发电机3代替驱动电机2与发动机1混合驱动，如此还能够获得其它多种混合驱动模式，而使得本混合动力系统的驱动模式更为丰富。
最后，本实施例也进一步涉及一种混合动力汽车，该混合动力汽车中即搭载有如上所述的双电机混合动力系统。
而本实施例的混合动力汽车，通过搭载如上的双电机混合动力系统，可实现系统多模式及多挡位驱动，能够降低油耗，而可具有较好的实用性。
以上所述仅为本公开的较佳实施例而已，并不用以限制本公开，凡在本公 开的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
