并且，电机200、变速器400和控制器500集成化设置，相比相关技术中的动力总成，可以避免电机总成、变速器总成和控制器总成单独设置浪费空间，便于缩短电动总成1的轴向距离，使电动总成1的结构紧凑合理，提高电动总成1的空间利用率，便于电动总成1的设置。同时便于电动总成1的安装和维修，便于提高电动总成1的适用范围，便于提高电动总成1的可靠性和稳定性。
此外，通过电机200和变速器400共用一个箱体总成100，便于减轻电动总成1的重量，例如当电动总成1应用于车辆11中，可以降低所述车辆11的整体重量，便于降低所述车辆11的成本，降低所述车辆11的能量损耗，提高所述车辆11的工作效率，提高所述车辆11的续航能力。

同时，控制器500安装在箱体总成100上，电机200、变速器400和控制器500集成度高，相比相关技术中的电机总成，可以省去在控制器500与电机200之间设置外接三相线，便于优化电动总成1的结构，降低电动总成1的成本，避免安装外接三相线影响电动总成1的密封效果，防止电动总成1发生漏电，便于提高电动总成1的工作效率，提高电动总成1的抗干扰能力，降低电动总成1的故障率。
因此，根据本申请实施例的电动总成1具有结构紧凑、适用性强等优点。
下面参考附图描述根据本申请具体实施例的电动总成1。
在本申请的一些具体实施例中，如图1-图32所示，根据本申请实施例的电动总成1包括箱体总成100、电机200、变速器400和控制器500。
根据本申请的一个实施例，控制器500与电机200直接电连接。这样便于简化电动总成1的结构，提高电动总成1的集成度水平。
根据本申请的另一个实施例，如图9所示，控制器500位于箱体总成的上方(上下方向如图10中的箭头A所示)。这样便于控制器500的设置。
具体地，如图9所示，控制器500位于电机200和变速器400的上方。具体而言，控制器500可以是位于电机200的上方也可以是位于变速器400的上方，可以是电机200与 控制器500直接接触，也可以不接触。例如，控制器500同时安装在电机200和变速器400的上方，变速器400位于电机200的水平方向的一侧，变速器400位于电机200的后侧，控制器500位于变速器400和电机200构成的整体的上方。
更为具体地，电动总成1的高度与宽度之比的范围为0.6-0.9(电动总成1的长度方向、宽度方向和高度方向如图11所示)。这样在电动总成1的高度与宽度之比最大值时，可以降低电动总成1的高度，在整车总成高度限制的情况下进行布置。最小值时，可以减小横向尺寸，在整车总成横向尺寸要求小的情况下进行布置。
具体地，电机200的额定输出功率为70KW，电机200的额定转速为14000r/min,变速器400的速比为10.7，电动总成1的高度范围为350mm至370mm,电动总成1的长度范围为410mm至430mm,电动总成1的宽度范围为440mm至460mm，箱体总成100的高度范围为250mm至270mm。
具体地，电机200的额定输出功率为70KW，电机200的额定转速为14000r/min,变速器400的速比为8.5，电动总成1的高度范围为350mm至370mm,电动总成1的长度范围为410mm至430mm,电动总成1的宽度范围为440mm至460mm，箱体总成100的高度范围为250mm至270mm。
更为具体地，电机200的额定输出功率为120KW，电机200的额定转速为14000至15000r/min,变速器400的速比为9.3，电动总成1的高度范围为320mm至340mm,电动总成1的长度范围为470mm至490mm,电动总成1的宽度范围为470mm至490mm，箱体总成100的高度范围为230mm至250mm。
可选地，箱体总成100的上表面与控制器500的下表面接触，控制器500的下表面通过螺栓固定在箱体总成100上。这样便于控制器500的设置，便于提高控制器500的结构稳定性。
根据本申请的另一个实施例，如图10所示，变速器500与电机200共同限定出折角空间40，变速器400的半轴伸出至折角空间40，控制器500安装于所述半轴的上方。具体地，电机200安装在变速器400水平方向的一侧，变速器400的传动轴(附图未示出)与电机200连接，变速器400的半轴安装在电机200位于变速器400的同一侧，变速器400的半轴与电机200的轴向平行，折角空间40由电机200和变速器400限定出，折角空间40位于电机200朝向变速器400的半轴的一侧，并且折角空间40位于变速器400朝向电机200的一侧。
如图11所示的实施例中，电机200同时安装在电机200和变速器400上，控制器500与电机200电连接，控制器500用于控制电机200的启动、停止、转速等，控制器主体设置在折角空间40内。可以理解地是，控制器主体是指控制器500的功能承载部分，即实现 控制功能的部分，而不包括安装的支架等部分。控制器500设置在变速器400的与电机200相同的一侧，同时控制器500设置在电机200的与变速器400的半轴相同的一侧，控制器500、变速器400和电机200集成于一体，指的是控制器500、变速器400和电机200三者在结构空间上构成一个整体。可以理解的是，控制器500不仅仅可以安装在电机200和变速器400集成的箱体总成100上，也可以只安装在电机200的箱体上，或者只安装在变速器400的箱体上。
根据本申请实施例的电动总成1，通过在变速器400和电机200之间限定出折角空间40，控制器主体控制器500、变速器400和电机200集成于一体，使得电动总成1结构紧凑，控制器500安装在变速器400和电机200上，无需在控制器500和电机200之间设置较长的三相线等线束，节省了安装空间，使电动总成1的整体简洁美观。再者，减少了控制器500在车架上的安装点，简化了整车结构，减少了装配工序，降低生产成本和开发成本，电动总成1重心降低，以及整体的高度降低，因此对整车的安装空间要求降低，可以同时适用前驱和后驱车辆，对电动总成1的振动和整车重心都有益处。
此外，由于控制器主体设置在折角空间40内，可以利用折角空间40的空间，从而将控制器500向下移动至折角空间40内，进而降低电动汽车的动力总成100的整体高度。
具体地，所述半轴端部设置有球笼，控制器500位于所述球笼上方，控制器500与所述球笼不接触。由于所述球笼在各种变形下都可以将动力传送出去，这样便于动力的传递，控制器500安装于球笼上方，避免控制器500与球笼接触由于球笼振动损坏控制器500。
根据本申请的另一个实施例，如图12和图13所示，控制器500与电机200分别安装于变速器400的同侧或者两侧。
如图12所示，电机200位于变速器400的前侧，控制器500位于变速器400的后侧，此时电机200和控制器500可以在水平方向上分别位于变速器400的前后两侧。当然，可以理解的是，控制器500也可以位于变速器400的前侧，电机200也可以位于变速器400的后侧。
如图13所示，控制器500安装于电机200的前端，电机200安装于变速器400的前侧，此时控制器500和电机200均位于变速器400的前侧。如图6所示，控制器500也可以安装于电机200的右侧，电机200安装于变速器400的前侧，此时控制器500和电机200均位于变速器400的前侧。当然，可以理解的是，控制器500和电机200也可以均位于变速器400的后侧。
根据本申请的另一个实施例，如图14所示，电动总成1还包括导电片20，导电片20用于连接控制器500和电机200。例如，导电片20具有控制器接线端和电机接线端，所述控制器接线端用于连接控制器500，例如连接控制器500的三相线，所述电机接线端用于 连接电机200，例如连接电机200的三相线，导电片20通过螺栓固定于控制器500。这样可以省去外接三相线和接线座，三相线长度减小，省去接线座结构，成本降低。
具体地，电机200包括电机主体203和接线装置204，接线装置204安装于电机主体203上，电机主体203具有多条引线2031，接线装置204包括多个导电片20，多个导电片20分别与对应的引线2031相连，其中，导电片20具有控制器连接端，导电片20的所述控制器连接端用于直接连接控制器500。
换言之，控制器500直接连接导电片20一端的所述控制器连接端，导电片20的另一端连接电机主体203的引线2031(引线可以是电机绕组的引线)，这样，控制器500可以控制电机主体203，并且通过导电片20连接电机控制器100和电机主体203可以使电机200的整体结构更加紧凑。
一些具体实施例中，接线装置204还包括支撑板2042，支撑板2042相对固定地安装于电机主体203上，支撑板2042上设有定位嵌件20421，定位嵌件20421的两端分别伸出支撑板2042上相对的两侧表面，且导电片20的一部分嵌入于定位嵌件20421内，导电片20的所述控制器连接端伸出定位嵌件20421。换句话说，支撑板2042固定安装于电机主体203上，定位嵌件20421伸出支撑板2042的两侧，导电片20嵌入定位嵌件20421内且两端伸出定位嵌件20421一部分用于分别与引线2031和所述控制器连接端相连，其中，定位嵌件20421对导电片20提供支撑定位。
进一步地，多个导电片20并排设置且相互间隔开。可以理解的是，相互间隔开的多个导电片20可以避免发生短路或者连接混乱的情况出现。
也就是说，导电件10的电机接线端与导电片20一一对应连接，导电件10与导电片20电导通，导电件10与导电片20直接连接，不需要导线或其它连接装置，这样，可以使电机总成1的线路变短，提高了抗干扰能力，且极大的节省了空间。
一个具体实施例中，导电件10与导电片20螺钉连接。螺钉连接为自锁连接，连接稳定不易松动，且拆装方便。当然，上述实施例仅是示意性的，并不能理解为对本申请保护范围的限制，例如，导电件10与导电片20之间可以是插接、卡接、焊接或铆接等。
根据本申请的另一个实施例，如图17所示，电动总成1还包括导电片20，导电片20卡接在控制器500或导电片20通过螺栓固定于控制器500。导电片20具有控制器接线端和电机接线端，所述控制器接线端用于连接控制器500，例如连接控制器500的三相线，所述电机接线端用于连接电机200，例如电机200的三相线，导电片20卡接在控制器500。这样便于导电片20的拆卸和安装，并且可以省去外接三相线和接线座，三相线长度减小，省去接线座结构，成本降低。
具体地，电机总成1包括电机200和控制器500。电机200包括电机主体203和接线 装置204，接线装置204安装于电机主体203上，所述电机主体203具有多条引线2031，所述接线装置204包括多个导电片20，多个所述导电片20分别与对应的所述引线2031相连，所述导电片20具有控制器连接端。所述电机控制器100安装于所述电机200上，所述电机控制器100具有导电件10，所述导电件10具有用于连接电源的电源连接端和用于直接连接电机200的电机连接端2212，其中，所述导电件10的电机连接端2212和所述电极片的控制器连接端中的一个具有插接结构且另一个与所述插接结构插接连接。
换言之，导电件10的电源连接端连接电源，导电件10的电机连接端2212与导电片20的控制器连接端相连，也即电机控制器100直接连接导电片20一端的所述控制器连接端，导电片20的另一端连接电机主体203的引线2031(引线2031可以是电机绕组的引线)，这样，电机控制器100可以控制电机主体203，并且通过导电片20连接电机控制器100和电机主体203可以使电机200的整体结构更加紧凑。
此外，导电件10的电机连接端2212与电机200的导电片20之间通过插接结构相连，可以理解的是，相较于绝缘线路走线的方式，插接连接方式简单，简化了工序，节省时间。而且遇到磕碰情况时可以保证电机导电片20完整，减少折弯、折断导电片20等情况的出现。
也就是说，导电件10的电机连接端2212与导电片20一一对应连接，导电件10与导电片20电导通，导电件10与导电片20直接连接，不需要导线或其它连接装置，这样，可以使电机总成1的线路变短，提高了抗干扰能力，且极大的节省了空间。
一些实施例中，导电片20上设有限位槽，所述插接结构的上设有限位凸部，所述限位凸部适于扣入所述限位槽内。所述插接结构与导电片20连接时，所述限位凸部与限位凹槽配合，这样，可以增大插接片2211与电导电片20之间的接触面积，且可以防止插接片2211在震动的过程中与导电片20之间出现短暂脱离，防止接触不良的情况出现。
根据本申请的另一个实施例，控制器500具有控制器冷却水路且控制器500设有分别与所述控制器冷却水路连通的控制器水路进口接头和控制器水路出口接头，电机200具有电机冷却水路且电机200设有分别与所述电机冷却水路连通的电机水路进口接头和电机水路出口接头，所述控制器水路出口接头与所述电机水路进口接头通过螺栓相连。
根据本申请实施例的电动总成1，通过将电动总成和电机200直接对接相连，缩短水路，不用外接橡胶水管，该电动总成1的结构紧凑，集成度较高，因此空间利用率较高。
具体而言，如图19结合图20所示，电机200具有第一冷却流道11，第一冷却流道11具有第一接口111和第二接口112。控制器500具有第二冷却流道21，第二冷却流道21具有第三接口211和第四接口212，控制器500安装于电机200上。其中，第二接口112与第三接口211对接，且第二接口112与第三接口211对接处的周围具有第一密封结构31。
也就是说，电机200和控制器500之间的冷却水道采用直接对接达到冷却水循环的目的，冷却水的循环步骤如下：水箱冷却水从控制器500的第四接口212位置进入第二冷却流道21，冷却控制器500内的相关元器件后从第三接口211位置流出，由于第三接口211与第二接口112对接，水流通过电机200上的第二接口112位置进入电机200，冷却电机200内的相关元器件后从第一接口111位置回到水箱，实现冷却水循环，完成冷却系统的功能。
其中，如图20所示，第二接口112与第三接口211直接对接，中间不需要管道的连接，电机200与控制器500的结构更加紧凑，集成度较高，可以提高空间利用率。需要说明的是，第三接口211与第二接口112对接中的所述对接指第三接口211与第二接口112同轴的对接，换言之，第二接口112与第三接口211对接之后，第二接口112与第三接口211同轴，这样，第二接口112与第三接口211连接稳定、合理，冷却水从第二冷却流道21进入第一冷却流道11的流速以及流动方向较为稳定。
此外，第一密封结构31起到了密封作用，可以防止冷却水通过第二接口112和第三接口211的连接处时发生泄露，从而引发安全隐患。
其中，第一密封结构31优选地为密封圈，密封圈的来源广泛，且价格较低，也便于安装，密封圈可以根据接口的形状设计，也可以起到平衡误差的作用。当然，上述实施例仅是示意性的，密封圈第一密封结构31并不限于为密封圈，第一密封结构31也可以通过过盈配合、液压或气压等结构来实现密封效果。
根据本申请的另一个实施例，如图21所示，控制器500具有控制器冷却水路且控制器500设有分别与所述控制器冷却水路连通的控制器水路进口接头和控制器水路出口接头，电机200具有电机冷却水路且电机200设有分别与所述电机冷却水路连通的电机水路进口接头和电机水路出口接头，所述控制器水路出口接头与所述电机水路进口接头插接相连。具体而言，电机水路进口接头13可以设在电机200邻近控制器500的一侧，控制器水路出口接头32可以设在控制器500邻近电机200的一侧，冷却水由控制器水路进口接头33进入控制器500的内部水路，冷却水由控制器水路出口接头32流出，经由电机水路进口接头13进入电机200内部水路，最后冷却水由电机水路出口接头14流出。由此，电机200和控制器500共用一套水冷系统，省略了连接控制器水路出口接头32和电机水路进口接头13的水管，从而缩短了冷却水循环路径和时间，增强了冷却效果，节约了成本。
具体地，箱体总成100内具有相互连通的电机容纳腔103和变速器容纳腔104，电机200设在电机容纳腔103内，变速器400设在变速器容纳腔104内。这样便于电机200和变速器400的设置，进一步便于提高电动总成1的空间利用率，便于使电动总成1的结构更加紧凑合理。
更为具体地，电机容纳腔103和变速器容纳腔104沿电机轴210的轴向排列，箱体总成100内具有连通电机容纳腔103和变速器容纳腔104的轴过孔130，电机轴210和主轴300中的至少一个穿过轴过孔130与另一个相连。这样便于电机轴210和主轴300相互连接，便于电机200将动力顺畅地传递到变速器400，便于提高电动总成1的传动可靠性。
可选地，如图1所示，电动总成1还包括密封腔体600，密封腔体600一体形成在箱体总成100靠近电机容纳腔103的一端的端面上且与电机容纳腔103和控制器500连通，电机200具有端子，所述端子穿过密封腔体600与控制器500直接电连接。这样便于电机200与控制器500直接电连接，便于提高电动总成1的密封性。
进一步地，控制器500安装在箱体总成100的周面上且支撑在密封腔体600上。这里需要理解的是，箱体总成100的周面是指电机轴210的轴向上的端面以外的面。这样密封腔体600可以起到支撑控制器500的作用，可以使电动总成1的结构更加合理紧凑，便于节省控制器500的安装空间，便于提高电动总成1的空间利用率。
具体地，如图4所示，密封腔体600包括腔体本体610和腔体盖板620，腔体本体610一体形成在箱体总成100上，腔体盖板620可拆卸地安装在腔体本体610上。具体而言，腔体盖板620拆卸后可以敞开腔体本体610。这样便于密封腔体600的拆卸和安装，便于对密封腔体600内的结构进行维护，便于提高电动总成1的维护效率。
更为具体地，如图4所示，箱体总成100包括电机段110和变速段120，电机段110的两端分别与密封腔体600和变速段120相连，控制器500的两端分别支撑在变速段120和密封腔体600上。这样便于电机200、变速器400和控制器500的设置，便于箱体总成100对电动总成1进行保护，便于提高电动总成1的结构稳定性。
进一步地，如图3所示，控制器500大体为长方体形且在水平面上具有相互平行的两个横边510和相互平行的两个纵边520，变速段120和密封腔体600分别邻近两个横边510设置，电机段110的轴向与纵边520平行且邻近两个纵边520中的一个且纵边520支撑在电机段110上。具体而言，控制器500的两个横边510分别支撑在变速段120和密封腔体600上，控制器500的一个纵边520支撑在电机段110上。这样控制器500的三条边分别支撑在箱体总成100和密封腔体600上，便于提高控制器500的稳定性和可靠性。
具体地，控制器500上设有直流母线550，直流母线550邻近一个横边510设置。这样便于实现控制器500的控制功能。
可选地，如图5和图6所示，电动总成1还包括水冷连接管700，控制器500上设有与冷却水源连通的水冷进口530，箱体总成100上设有与电机容纳腔103连通的水冷出口140，控制器500通过水冷连接管700与电机容纳腔103连通。具体而言，箱体总成100端面设有电机进水口170，控制器500靠近密封腔体600的一端端面设有控制器出水口540， 电机进水口170位于密封腔体600下方，电机进水口170和水冷出口140分别位于电机容纳腔103的两个端面上。由于电机200和控制器500共用一套水冷系统，冷却水由水冷进口530进入控制器500的内部水路，冷却水由控制器出水口540流出，经由水冷连接管700和电机进水口170进入电机200内部水路，最后冷却水由水冷出口140流出，这样便于缩短冷却水的循环路径和冷却水的循环时间，便于提高冷却水的冷却效果，便于保证电机200和控制器500的使用性能。同时可以提高电动总成1的集成度，进一步简化电动总成1的结构。
具体地，如图23所示，箱体总成100内设有安装板160，安装板160将箱体总成100内的空间分隔出沿电机轴210的轴向排列的电机容纳腔103和变速器容纳腔104，安装板160上具有连通电机容纳腔103和变速器容纳腔104的轴过孔130。电机200与变速器400动力耦合连接。
根据本申请实施例的电动总成1，通过将电机200和变速器400设在箱体总成100内，相比相关技术中变速器的前箱体与电机的前端盖连接的电机总成，电机200和变速器400共用一个箱体总成100，实现电动总成1的一体化设计，不仅可以省去设置多个箱体总成100结构，而且可以省去连接电机总成和变速器总成所需的螺栓，便于简化电动总成1的结构，减少电动总成1的零件数量，提高电动总成1的集成度，提高电动总成1的生产效率。
并且，电机200和变速器400共用一个箱体总成100，相比相关技术中的电机总成，可以避免电机总成和变速器总成单独设置浪费空间，便于缩短电动总成1的轴向距离，使电动总成1的结构紧凑合理，提高电动总成1的空间利用率，便于电动总成1的设置。同时便于电动总成1的安装和维修，便于提高电动总成1的可靠性和稳定性。
此外，通过电机200和变速器400共用一个箱体总成100，便于减轻电动总成1的重量，例如当电动总成1应用于车辆11中，可以降低所述车辆11的整体重量，便于降低所述车辆11的成本，降低所述车辆11的能量损耗，提高所述车辆11的工作效率，提高所述车辆11的续航能力。
同时，通过设置箱体总成100箱体总成100内设有安装板160，装配过程仅需要进行一次装夹，便于电动总成1的装配成型，便于减小电动总成1的误差，便于电机200和变速器400的安装和设置，便于提高电机200和变速器400的同轴度和径向上安装的准确性，便于提高电动总成1的工作性能。
具体地，如图27和图28所示，安装板160朝向电机200的一侧设有筋条。由于所述筋条使得箱体总成100的刚度增强，固有频率提高，可以避免电动总成1发生共振，便于降低电动总成1的噪声。
更为具体地，所述筋条将安装板160与电机200之间的空间分隔为多个空腔。这样便于空腔162的形成，便于利用通过空腔162的空气对电机200进行冷却。
可选地，电机200与安装板160之间的最大距离小于预设距离。这里需要理解的是，所述预设距离为使安装板160对电机200进行冷却的最大距离。例如，电机200与安装板160之间的最大距离可以小于10毫米，优选为7.5毫米。由于预设值可以设置为一个较小的值，以使电机200和安装板160之间的距离很小，这样可以使得电机200和安装板160之间相互近距离冷却，在安装板160冷却后，电机200能快速得到冷却。
根据本申请的一个实施例，安装板160构造为前箱体180的一部分，因为变速器润滑液对前箱体180进行冷却，使安装板160和箱体总成100，例如电机壳体105和变速器箱体101也可以受到冷却。安装板160的所述筋条之间形成空腔162，因此，流过空腔162的空气也会随之冷却，利用流过空腔162的空气使得电机200可以冷却，便于提高电动总成1的散热性能。总之，通过变速器400内的润滑液可以同时对电机壳体105和变速器400的壳体进行冷却。
根据本申请的另一个实施例，安装板160构造为电机壳体105的一部分，因为电机润滑液对电机壳体105进行冷却，这样也可以对安装板160进行冷却，并通过安装板160传递热量，使变速器箱体101也可以受到冷却，从而使箱体总成100得到冷却，提高电动总成1的整体冷却效果。总之，通过电机200内的润滑液也可以同时对电机壳体105和变速器400进行冷却。
具体地，电机200转动过程中，应力通过轴承传递到箱体总成100，在箱体总成100上增加所述筋条，有利于增加箱体总成100的刚性和强度，避免箱体总成100与电机200的线圈接触，防止电机200的元器件发生损坏，进一步提高电机200的工作可靠性和稳定性。
根据本申请的一个实施例，如图31所示，所述筋条包括沿电机200的周向延伸的环形筋条163。这样可以提高箱体总成100的刚性和强度，提高箱体总成100的结构稳定性，提高箱体总成100的散热能力和冷却效果。

根据本申请的另一个实施例，所述筋条包括沿电机200的周向延伸的环形筋条163和沿电机200的径向延伸的条状筋条161，条状筋条161为多个且多个条状筋条161沿安装板160的周向间隔设置。这样可以同时提高箱体总成100沿电机200的周向和径向的刚性 和强度，提高箱体总成100的结构可靠性，进一步提高箱体总成100的散热面积，提高电动总成1的散热冷却性能。
具体地，条状筋条161距离安装板160的高度由内至外逐渐减小。这样可以减小条状筋条161的设置空间，避免条状筋条161占用箱体总成100内过多的空间，进一步便于电机200和变速器400的安装和设置。另一方面，条状筋条161距离安装板160高度由内至外逐渐减小，中心最高，可以承受轴承对箱体总成100形成的高强度载荷。

根据本申请的另一个实施例，电机壳体105和电机前端盖106通过螺栓连接，电机前端盖106和前箱体180通过螺栓连接，电机壳体105和电机后端盖150通过螺栓连接。这样便于电机壳体105、电机前端盖106、前箱体180和后箱体190的加工成型，便于简化成型工艺。电机壳体105前箱体180后箱体190电机后端盖150电机壳体105前箱体180后箱体190电机后端盖150电机壳体105前箱体180电机壳体105。由于电机前端盖106、电机壳体105和电机后端盖150均可拆卸，这样可以调节电机200的长度，例如电机壳体105可作为一个标准件单独调节长度，提高电机200的结构灵活性和应用范围。
