附图说明
下面结合附图对本发明技术方案作进一步说明：
图1：本发明第一实施例的结构示意图；
图2：本发明第二实施例的结构示意图。
具体实施方式
以下将结合附图所示的具体实施方式对本发明进行详细描述。但这些实施方式并不限于本发明，本领域的普通技术人员根据这些实施方式所做出的结构、方法、或功能上的变换均包含在本发明的保护范围内。
如图1所示，本发明揭示了一种基于混合动力的四挡变速器驱动系统，包括设置在变速器壳体内相互平行且可自转地输入轴1和第一输出轴2，所述第一输入轴1和第一输出轴2均没有相互嵌套，安装方便。所述输入轴1和第一输出轴2之间通过第一齿轮组件传动连接。进一步的，所述第一齿轮组件至少包括空套在所述第一输出轴2上的一挡主动齿轮21和二挡主动齿轮22，以及固设在所述输入轴1上与所述一挡主动齿轮21相啮合的第一联动齿轮11和与所述二挡主动齿轮22相啮合的第二联动齿轮12；所述第一齿轮组件还包括设置在所述第一输出轴2上位于所述一挡主动齿轮21和二挡主动齿轮22之间的一二同步器23，所述一二同步器23可选择地与所述一挡主动齿轮21或二挡主动齿轮22传动连接。
本发明中，所述输入轴1的一端通过离合器3与发动机4连接，所述离合器3与发动机4之间还设有设置在所述发动机4机轴上的飞轮41，所述飞轮41的设置可为发动机提供惯性及稳定输出。另一端与驱动源5连接，本发明的第一实施例中，所述驱动源5为固设在所述输入轴1上的辅助电机51。下面简单阐述一下所述辅助电机31，所述辅助电机31是汽车起动发电一体机，直接集成在输入轴上，就是直接以某种瞬态功率较大的电机替代传统的电机，在起步阶段短时替代发动机驱动汽车，并同时起到启动发动机的作用，减少发动机的怠速损耗和污染，正常行使时，发动机驱动车辆，所述辅助电机31断开或者起到发电机的作用，刹车时，所述辅助电机31还可以起到再生发电，回收制动能量的节能效果。总之这是一种介于混合动力和传统汽车之间的一种成本低廉的节能和环保方案。
本发明中，所述第一输出轴2的一端上固设有驱动其转动的驱动组件6，其中，所述驱动组件6包括固设在所述第一输出轴2任一一端的第一相连齿轮61，所述第一相连齿轮61通过第二相连齿轮62与所述第三相连齿轮63传动连接，所述第三相连齿轮63固设在所述主驱动电机64的电机轴上。
本发明还包括设置在变速器壳体内与所述第一输出轴2平行的第二输出轴7，所述第二输出轴7和第一输出轴2之间通过传动组件8与差速器9的连接齿轮91直接连接，所述差速器9的连接齿轮91连接于车辆的轮毂。所述传动组件8包括固设在所述第一输出轴2上的第三传动齿轮81和固设在所述第二输出轴7上的第四传动齿轮82。
进一步的，所述第二输出轴7还通过第二齿轮组件与所述输入轴1传动连接，具体的，所述第二齿轮组件包括空套在所述第二输出轴7上与所述第一联动齿轮11相啮合的三挡主动齿轮71和与所述第二联动齿轮12相啮合的四挡主动齿轮72，所述三挡主动齿轮71和四挡主动齿轮72之间还设有设置在所述第二输出轴7上的三四同步器73，所述三四同步器73可选择地与所述三挡主动齿轮71或四挡主动齿轮72传动连接。所述第二输出轴7的一端上还设有驻车棘轮 79，所述驻车棘轮 79与所述第四传动齿轮82贴近。
下面简单阐述一下本发明的工作过程：
当车辆处于倒挡状态时，所述离合器3处于分离状态，所述主驱动电机64启动并反转，所述主驱动电机64转动通过所述第三相连齿轮63、第二相连齿轮62和第一相连齿轮61带动所述第一输出轴2转动，所述第一输出轴2转动通过所述第三传动齿轮81驱动所述差速器9的连接齿轮91转动，实现倒挡。
当车辆处于一挡纯电驱动状态时，所述离合器3处于分离状态，所述主驱动电机64启动并转动，所述主驱动电机64转动通过所述第三相连齿轮63、第二相连齿轮62和第一相连齿轮61带动所述第一输出轴2转动，所述第一输出轴2转动通过所述第三传动齿轮81驱动所述差速器9的连接齿轮91转动，实现一挡驱动。
当车辆处于二挡、三挡、四挡纯电驱动状态时，其动力传递路线与一挡动力传递路线一致，就不过过多赘述，仅需改变所述主驱动电机64的转速即可。
当车辆处于一挡混合驱动状态时，所述主驱动电机64启动并转动，所述主驱动电机64转动通过所述第三相连齿轮63、第二相连齿轮62和第一相连齿轮61带动所述第一输出轴2转动，所述第一输出轴2转动通过所述第三传动齿轮81驱动所述差速器9的连接齿轮91转动。同时，所述离合器3处于闭合状态，所述发动机4通过离合器3驱动所述输入轴1以及固设在所述输入轴1上的第一联动齿轮11转动，又因所述第一联动齿轮11与所述一挡主动齿轮21相啮合，所以所述一挡主动齿轮21开始转动。所述一挡主动齿轮21转动通过第一输出轴2和第三传动齿轮81驱动所述差速器9的连接齿轮91转动，，实现一挡混动模式驱动。
当车辆处于二挡、三挡、四挡混合动力驱动状态时，其动力传递路线与一挡动力传递路线雷同，就不过过多赘述。
另外，车辆在由所述主驱动电机单独驱动时，可将车辆驱动至高效经济器，待车辆进入高效经济区工作的车速时，所述辅助电机预先启动所述发动机并使其在高效经济区车速中介入驱动，实现并联混动，并可逐渐代替电机驱动，可极大地降低油耗，大大地节省成本。同时，所述发动机在换挡过程中，所述主驱动电机可补充动力差值保证系统换挡时动力不中断，提升驾驶的舒适性。
本发明中的另一设计要点在于：通过该设计，在混动过程中实现所述输入轴1和第一输出轴2上的两个功率相加。又因为功率是衡量汽车最高速度的物理量，功率越大的汽车的最高速度也越大，其爬坡性能以及加速性能也愈好。同时，所述输入轴1和第一输出轴2均有单独的驱动装置驱动，可以彼此独立的输出贡献扭矩。
如图2所示，为本发明的第二实施例，其是在第一实施例的基础上作相应的修改，其修改如下：所述驱动源5至少包括辅助电机51，所述辅助电机51的电机轴上固设有一第一传动齿轮59，所述第一传动齿轮59与固设在所述输入轴1上的第二传动齿轮19相啮合。进一步的，所述差速器9上设有一驻车棘轮 79。
本发明的有益效果主要体现在：
1、结构简单，设计巧妙，本系统中电机均与输入轴直接连接，减小力臂，可以减小扭矩，避免输入轴承受过大扭矩所导致的输入轴断裂情况的发生，同时，三轴式布置，数比匹配更简单，且变型容易；
2、车辆启动时，离合器处于分离状态，以主驱动电机进行驱动，驱动车辆至发动机可在高效经济区工作的车速时，辅助电机预先启动发动机并使其在高效经济区车速中介入驱动，实现并联混动，并可逐渐代替电机驱动，可极大地降低油耗，大大地节省成本；
3、在发动机换挡过程中主驱动电机补充动力差值保证系统换挡时动力不中断，提升驾驶的舒适性；
4、将传统意义上的倒挡去掉，通过主驱动电机倒转即可实现倒挡；
5、在主驱动电机单独工作的情况下，如电池包电量低于一定的设定值，辅助电机启动发动机，发动机启动至高效经济区通过辅助电机发电直接驱动主动电机或为电池包充电，当停车状态下发动为电池包补充电量；
6、车辆制动时，通过主驱动电机进行回收能量，避免能量的浪费；
7、发动机可在任一挡位上均可工作，实现较大范围的介入，适用于更多复杂的工况；
8、在特殊工况，如急加速、大坡度启动等需求大扭矩输入时，主驱动电机输出不足的情况下，辅助电机可通过轴系与主驱动电机协同工作；
9、辅助电机在发动机并联介入系统工作时，可产生负载使发动机尽量逼近高校区工作，且产生的负载可用于发电，更节能。
