Description

集成式启动发电一体化电机及一种混合动力动力系统 技术领域
本发明涉及一种集成式启动发电一体化电机，具体涉及电机中转子和定子的安装结构。本发明还涉及一种混合动力动力系统。
发明背景
启动发电一体化电机是车辆电气化、混合动力化方案里的一种重要部件。主要分为皮带传动启动发电一体化电机(BSG:Belt-driven Starter Generator)和集成式启动发电一体化电机(ISG:Integrated Starter Generator)两种。
ISG直接安装在内燃机曲轴输出端，取代了原本分开的内燃机启动机和发电机，同时也可以作为车辆的辅助动力源使用。作为车辆电气化、混合动力化解决方案，ISG电机具有内燃机启停、发电、制动和动力辅助等功能，帮助车辆节约燃油消耗、降低排气碳污染。而相比于BSG，ISG不使用皮带，也就省去了皮带的维护负担。
现有使用ISG的混合动力系统中，ISG、离合器和驱动电机在传动轴方向上一般采用串式布置。其优点是结构简单，而缺点是轴向占用空间大、有较大的质量，同时也需要较高的制造成本。
例如在中国发明专利“一种电磁齿嵌式离合器和双电机混联系统”(CN103758889A)中，说明书附图4公开了一种双电机混联系统，其中包括ISG电机，电磁齿嵌式离合器和驱动电机，这些部件均是串式布置。
此外在现有技术中，涉及内燃机和驱动电机的混合动力系统，通常都是采用串式布置。
例如在中国发明专利“一种起动发电一体电机的转子装置和转子工作系统”(CN101964556B)中，说明书附图8公开了一种混合动力系统，其中包括发动机，曲轴，与曲轴连接并一起转动的转子装置，与转子装置连接的离合器，与离合器连接的变速箱，这些部件依次串式布置。
在中国发明专利“一种混合动力系统”(CN104315090A)中，说明书附图1公开了一种混合动力系统，其中包括动力源A内燃机，离合器和动力源B电机，这些部件均是串式布置。

进一步，所述转子的铁芯在面向定子的一侧设置齿槽安装所述鼠笼导体，所述鼠笼导体设置有两个同心的短路环，分为内环和外环，两个短路环之间均布有若干根导条。
进一步，所述转子的铁芯在面向定子的一侧设置有若干凹槽安装所述永磁体，每块所述永磁体呈扇形。
一种混合动力系统，设置有内燃机和驱动电机，所述内燃机连接曲轴，所述曲轴输出端连接离合器，所述离合器连接驱动电机主轴，所述驱动电机主轴连接变速箱，所述变速箱连接驱动轴；所述离合器包括动端面齿轮和定端面齿轮；所述混合动力动力系统还设置有上述的集成式启动发电一体化电机，所述离合器嵌套在所述集成式启动发电一体化电机的内环之中。
进一步，所述集成式启动发电一体化电机的转子安装固定在所述离合器的定端面齿轮上；所述集成式启动发电一体化电机的定子安装固定在所述驱动电机的外壳上。
进一步，所述转子的铁芯和定子的铁芯上均设置有座板，所述座板上设置有安装孔，通过螺栓安装固定；所述驱动电机内的降温系统同时对所述定子进行冷却。
进一步，所述离合器采用电磁齿嵌式离合器，围绕所述离合器的定端面齿轮设置有环形或扇形电磁铁。
采用上述结构设置的集成式启动发电一体化电机构具有以下优点：

实施本发明的方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
实施例1
如图3、图4、图5所示为本发明实施例之一，在该实施例中，集成式启动发电一体化电机(ISG电机)，包括定子和转子，定子和转子相对设置，定子和转子均设置有环形铁芯，定子的铁芯120在面向转子的一侧设置有线圈绕组121，转子的铁芯122在面向定子的一侧设置有鼠笼导体123。
在本实施例中，转子与定子间隔预定距离形成气隙平面。该气隙平面是垂直于转子和定子的轴向的。
线圈绕组121的磁极沿定子的轴向分布。
如图4、图5所示，定子的铁芯120在面向转子的一侧设置有齿槽1201安装线圈绕组121，线圈绕组121采用集中式绕组。
定子中漆包线的绕组方式为分数槽集中绕组(Fractional Slot Concentrated Winding)，即定子的槽数比上级数和相数的乘积(Number of Slots per Pole per Phase)是小于一的分数。这样的绕组好处是绕组端部尺寸较小，节约漆包线的使用，因此降低成本。
当然，线圈绕组121也可以采用分布式绕组。
转子的铁芯122在面向定子的一侧设置齿槽1221安装鼠笼导体123。
为了提高电机效率，定子和转子的相对面积是基本相等的。
如图4、图8所示，鼠笼导体123设置有两个同心的短路环，分为内环和外环，两个短路环之间均布有若干根导条。该结构的鼠笼导体是为了适应磁极轴向分布的定子而设计的。
实施例2
在该实施例中，如图11、图12所示，转子的铁芯132在面向定子的一侧设置有若干块永磁体133。
永磁体133的磁极沿转子的轴向分布。
采用永磁体相比于鼠笼导体，能够降低转子损耗。
转子的铁芯132在面向定子的一侧设置有若干凹槽安装永磁体133，每块永磁体133呈扇形。
定子仍然采用和实施例1类似的结构，定子的铁芯130在面向转子的一侧设置有齿槽1301安装线圈绕组131，线圈绕组131采用集中式绕组。
实施例3
在该实施例中，如图1、图2所示，一种混合动力系统，设置有内燃机110和驱动电机112，内燃机110连接曲轴117，曲轴117输出端连接离合器，离合器连接驱动电机112主轴，驱动电机112主轴连接变速箱113，变速箱113连接驱动轴114，驱动轴114连接差速器115，差速器115设置在驱动轮116的主轴上；离合器包括定端面齿轮2和动端面齿轮6；混合动力动力系统还设置有集成式启动发电一体化电机，离合器嵌套在集成式启动发电一体化电机的内环之中，包括定端面齿轮2和动端面齿轮6均位于集成式启动发电一体化电机的内环之中。
在该实施例中，离合器采用电磁齿嵌式离合器，围绕离合器的定端面齿轮2设置有环形或扇形电磁铁，相应地动端面齿轮6上可以设置衔铁。
集成式启动发电一体化电机采用实施例1或实施例2中的结构。驱动电机112是驱动轴114的驱动电机，驱动电机112的主轴与离合器之间还设置有从动轴5。
集成式启动发电一体化电机的转子3安装固定在离合器的定端面齿轮2上；集成式启动发电一体化电机的定子4安装固定在驱动电机112的外壳上。
由于定子4安装固定在驱动电机112的外壳上，驱动电机112内的降温系统可以同时对定子4进行冷却，从而优化了定子结构。
转子3和动端面齿轮2的转速始终是相同的。
集成式启动发电一体化电机的安装需要满足：在离合器的定端面齿轮2和动端面齿轮6啮合和分离过程中，转子3和定子4之间存在适当的间隙。
为了安装转子3和定子4，可以采用这样的结构，在转子3的铁芯和定子4的铁芯上均设置有座板，座板上设置有安装孔，通过螺栓安装固定(未图示)。
座板可以是耳板，以铁芯为基础向内环或者外环延伸。座板也可以是座圈，以铁芯为基础向内环或者外环延伸。
也可以在转子3的铁芯和定子4的铁芯上均设置多个螺纹孔，直接将固定螺栓安装在铁芯上，再分别与动端面齿轮2、驱动电机112的外壳连接。
以上所述仅为本发明的较佳实施例而已，并非用于限定本发明的保护范围。凡在本发明的精神和原则之内所作的任何修改、等同替换、改进等，均包含在本发明的保护范围内。
