本申请要求于2020年5月27日提交的美国非临时专利申请No.16/884,208的权益，该美国非临时专利申请的公开内容通过参引整体并入本文中。
技术领域
本公开涉及用于模块化混合传动装置的驱动装置。
背景技术
汽车的OEM和OEM的一级供应商已经考虑了用于MHEV(微混电动车辆)的不同的主动力系结构。在这些结构中，电动马达可以相对于其他动力系部件定位在被称为P0至P4的五个主要的点处。如图3中所示出的，P0位于ICE(内燃发动机)的前端部处，并且通常是经由带向曲轴提供动力的前端辅助驱动部。P1提供至电动马达的曲轴的直接连接。P0结构和P1结构不允许电动马达与ICE机械断开连接。P2结构提供了ICE与能够从ICE断开连接的传动装置之间的侧面附接的马达。P3结构提供了由相互啮合的齿轮连接至传动装置的电动马达。最后，P4结构提供经由相互啮合的齿轮连接至驱动轴的电动马达。P2至P4结构都允许电动马达从ICE断开连接。
在汽车行业中已经使用了P1结构并且在一些小客车中可以发现P1结构，在该结构中，电动马达在车辆传动装置与下游传动系之前直接连接至曲轴。这种布置结构提供了安装至输入轴的混合电动马达的转子，该输入轴支撑在曲轴的先导部中，其中，该转子居中在定子中。然而，可能会由于支撑不足而在电动马达的转子与定子之间发生过早接触，这导致功能丧失。例如在MHT(模块化混合传动装置)中，轴承进一步远离转子的中央轴向位置，由于在MHT的情况下轴承更接近发动机侧，因此径向滚珠轴承的倾斜公差也可能导致转子与定子之间的过早接触。
在许多车辆应用中，也不能将车载电动驱动系统封装成使得常规车辆动力系结构可以与电动驱动装置一起应用。离轴解决方案经常消耗车辆地板驻留的空间，从而需要高成本地毁坏现有的工具和压模。P0应用具有的问题在于经由蛇形带进行扭矩传递并且因此不能用于高的扭矩收集或高的车辆增压，从而限制了马达位置的有效性。
已知的P1结构中的另一问题是定子的冷却。在许多这样的应用中，定子用单独的专用冷却系统来进行冷却。然而，这根据负载可能是不充分的。一个已知的解决方案使用两个不同的冷却路径来将油/传动装置流体传递至定子。油向下传递至传动装置侧的焊接板中的孔口，该孔口将油在多个位置喷洒到定子绕组上。在发动机侧，外壳凹穴具有填充通道的冷却油，并且油穿过在壳体中钻出的多个孔口喷洒到定子绕组上。
期望为主要用于增压目的的平台提供电气化并且不需要复杂的P2结构。还期望以紧凑且简单的方式提供这种布置结构，同时还提供对定子线圈进行附加冷却的可能性。
发明内容
本公开提供了具有旋转组件和壳体组件的模块化混合传动装置。旋转组件包括适用于连接至变矩器的转子组件、支撑转子的转子承载毂、以及输入轴。转子承载毂旋转地固定在输入轴上，并且输入轴具有构造成由曲轴支撑的前端部。输入轴构造成由曲轴驱动。壳体组件容纳旋转组件，并且包括具有外壁的壳体、定子组件和径向延伸的固定壁，定子组件连接至外壁、适于驱动转子，径向延伸的固定壁从外壁朝向输入轴延伸。固定壁包括平行于输入轴的外表面延伸的轴向延伸的壁部分，径向滚珠轴承将输入轴支撑在该轴向延伸的壁部分上。径向滚珠轴承优选地定位成与转子轴向对准。
在另一方面中，密封件设置在固定壁与输入轴之间，该密封件将固定壁的一侧的湿区域与固定壁的相对侧的干区域分开。
在一个布置结构中，阻尼器组件将输入轴驱动地连接至曲轴。滚子轴承可以位于输入轴的前端部上，该前端部支撑在曲轴的先导部中。
在一个布置结构中，旋转变压器转子连接至转子承载毂，并且对旋转变压器转子的位置进行感测的旋转变压器定子连接至固定壁。旋转变压器转子可以通过压入环连接至转子承载毂的内周径(ID)。
在一个布置结构中，保持器环连接至输入轴，保持器环将径向滚珠轴承保持就位。
为了允许进行扭矩传递，P1模块转接器板和P1模块挠曲板连接至输入轴并且构造成用于连接至变矩器。P1模块挠曲板连接至带花键凸缘，带花键凸缘通过保持环保持至输入轴。
在一个布置结构中，端部环将转子组件保持在转子承载毂上。
这种新的P1构型减少了电动马达的转子与定子之间的过早接触的发生。这种构型还使用了转子承载毂内周径下方的轴向空间，其中，固定壁在两个旋转组件之间向下延伸以连接至轴承，这对于封装外延型旋转变压器转子和旋转变压器定子而言减小了任何轴向长度的增加。
这种轴承布局结构允许将转子更好地定位至定子。这种轴承布局结构防止了电动马达的转子与定子之间的导致功能丧失的过早接触的发生。轴承的关于转子堆叠件的轴向位置还允许改善马达的功能，因为在操作期间轴承将倾斜以对未对准进行补偿。这种布局结构还通过将支撑固定部件置于旋转组件之下而利用了较少的轴向空间并且因此不需要增加动力系的轴向长度来包括该模块。
关于解决针对定子线圈的已知的冷却问题，本公开提供了包括旋转组件和壳体组件的模块化混合传动装置。旋转组件具有适用于连接至变矩器的转子组件、支撑转子的转子承载毂、以及输入轴。转子承载毂旋转地固定在输入轴上，并且输入轴具有构造成由曲轴支撑的前端部。输入轴构造成由曲轴驱动。壳体组件容纳旋转组件并且具有带有外壁的壳体。定子组件连接至外壁并且适于驱动转子。径向延伸的固定壁从外壁朝向输入轴延伸。冷却水端口设置在壳体外壁中，并且冷却水端口连接至邻近定子组件延伸的壳体凹穴。
在一个方面中，在壳体外壁中设置有冷却油端口，板连接至固定壁以限定与冷却油端口连通的冷却油通道，并且在固定壁中邻近定子组件的绕组限定有孔口，孔口构造成将冷却油在传动装置侧喷洒在定子绕组上。
在另一方面中，在壳体外壁中在与固定壁轴向相反的一侧限定有凹穴，并且壳体外壁中的前部孔口与该凹穴流体连通并且构造成将冷却油在发动机侧引导到定子绕组上。前部板可以用于密封凹穴。
这种冷却布局结构通过具有用于电动马达的附加专用冷却而增加了电动马达的工作能力。这是通过既对定子钢质层压件进行水套冷却又将油喷洒到定子绕组上来完成的。用于定子绕组的油冷却是通过孔口和壳体中的交叉钻孔以及密封至壳体的板来完成的。这些板可以被焊接上。
轴承布置结构和冷却布局结构可以分开地使用或者一起使用。
