Description

具有用于冷却剂泄漏的储存器的电机
技术领域
本发明涉及一种电机，该电机包括：壳体，其中容纳有定子和可相对于定子旋转的转子；带有冷却通道的冷却装置，冷却剂可以流过该冷却通道且该冷却通道从入口延伸穿过壳体和转子到达出口；以及用于相对于壳体的内部空间密封转子的密封装置。
背景技术
这种类型的电机越来越多地用于电驱动车辆或混合动力车辆。这里，电机主要用作驱动车辆车轮或车轴的电动机。电动机尤其可以配置为同步电动机或异步电动机。
电动机通常机械地联接到齿轮箱，以适应转速。电动机另外通常连接到逆变器，该逆变器根据由电池提供的DC电压产生AC电压，特别是多相AC电压，用于电机的运行。
电机也可以作为发电机运行，用于回收车辆的动能，其中动能首先转化为电能，然后转化为电池的化学能。
电机的转子通常具有由圆柱形转子体包围的转子轴。除了层叠金属板堆叠之外，转子体尤其还可以具有永磁体或带有电导体的绕组。
由于在电机运行期间产生的热量，电机具有用于散热的冷却装置，该冷却装置包括液体冷却剂可流过的冷却通道。冷却通道从入口延伸，穿过电机的壳体并向前穿过转子，到达形成在壳体中的出口。冷却剂例如水-乙二醇混合物在回路中输送。
密封装置相对于壳体密封转子，例如在转子的轴向方向和径向方向上。特别地，穿过转子的填充有冷却剂的冷却通道相对于壳体的内部空间被密封，使得没有冷却剂能够从冷却通道进入内部空间并导致那里的损坏，例如由于腐蚀。内部空间尤其可以容纳定子，或者可以填充有空气。
温度引起的壳体内部空气体积的变化需要提供通风和/或换气，以防止在壳体中产生负压或正压。为此，可以设置从密封装置延伸到壳体开口的通风通道。
已经发现，尽管有密封装置，但在电机运行期间，通过密封装置会发生至少少量的冷却剂技术泄漏。这种技术泄漏(冷却剂泄漏)尤其在电机以特定旋转方向运行时发生。在电力驱动车辆的情况下，泄漏可能发生在例如倒车行驶期间。
为了解决这个问题，已经提出在单独的储存器中收集技术泄漏，也就是说在为此目的提供的容器中。然而，在车辆维护过程中，该容器必须以一定的时间间隔清空。
发明内容
本发明的目的是提供一种能够以较少的费用运行的电机。
为了实现所述目的，在引言中所述类型的电机的情况下，根据本发明规定，在密封装置和壳体之间形成用于在转子旋转期间发生的冷却剂泄漏的储存器。
本发明基于的认识在于，用于收集冷却剂泄漏的单独容器可以省略，因为该功能由形成在密封装置和壳体之间的储存器来执行。这首先节省了结构空间，但更重要的是，可以省略在车辆维护过程中排空冷却剂泄漏。因此，根据本发明的电机可以在无需维护的情况下运行，从而节省成本。
密封装置优选地构造成在径向方向和轴向方向上密封转子。这防止了冷却剂从冷却通道中逸出，并进入例如转子轴的轴承中。径向方向上的密封可以通过径向轴密封环来实现。轴向方向上的密封可以通过机械混合密封来实现，例如用滑环密封。
此外，根据本发明的电机可以配置成使得在转子沿第一旋转方向旋转期间，由于少量的冷却剂经过密封装置而发生冷却剂泄漏。因此，少量的冷却剂从冷却剂回路中逸出，并作为泄漏收集在电机的壳体中。
由于密封装置的结构，冷却剂泄漏仅在转子沿第一旋转方向旋转期间发生。在使用电机驱动的车辆的情况下，第一旋转方向可被分配给车辆的反向行驶。冷却剂泄漏在重力的作用下聚集在腔的下部区域，即布置在密封装置和壳体之间的储存器中。储存器可以特别形成为围绕密封装置的自由空间的下部区域。
在根据本发明的电机中，特别有利的是，在转子沿与第一旋转方向相反的第二旋转方向旋转的过程中，冷却剂泄漏被再次输送出储存器。这意味着在车辆向前行驶期间，填充有冷却剂泄漏的储液器会自动排空。
因此，当车辆向前行驶时，会自动排空来自储存器的冷却剂泄漏。这里重要的是，冷却剂泄漏通过密封装置被供应回冷却回路。因此，冷却剂泄漏不需要收集在单独容器中，也不会进入环境中。
本发明的改进规定，转子或密封装置的可随转子旋转的部件具有导致冷却剂泄漏被输送出储存器的表面结构。因此，储存器可以特别容易地调节。表面结构尤其可以使得在转子沿第二旋转方向旋转期间，已经收集在储存器中的液体冷却剂被输送出储存器，并返回到冷却通道中。
为此目的，可旋转部件可以配置为滑环密封件的设置有表面结构的环，特别是作为上述滑环密封件的环，用于在轴向方向上密封转子。表面结构可以例如通过激光雕刻在环上。
在EP3190317A1中描述了这种环，并且该环可以具有螺旋形凹槽，借助于该凹槽，冷却剂可以从储存器泵送回冷却通道中。该环还可以具有所谓的瑞利台阶，其提高滑环密封件的滑动能力。
密封装置还可以具有径向轴密封环，其界定用于冷却剂泄漏的储存器。因此，储存器在径向轴密封件和电机壳体的内侧之间延伸。
上述目的还通过用于车辆的传动系来实现，该传动系具有根据本发明的电机。传动系可以另外具有联接到电机的齿轮箱和/或连接到电机的逆变器，通过该逆变器可以提供电机运行所需的多相AC电压。
该目的还通过具有所述类型的传动系的车辆来实现。
此外，本发明涉及一种用于运行电机的方法，该电机具有壳体，定子和相对于定子可旋转的转子容纳在该壳体中，具有包括冷却通道的冷却装置，冷却剂可以流过该冷却通道，该冷却通道从入口延伸穿过壳体和转子到达出口，还具有用于相对于壳体的内部空间密封转子的密封装置。
根据本发明的方法的特征在于，在密封装置和壳体之间形成用于在转子沿第一旋转方向旋转期间发生的冷却剂泄漏的储存器，其中在转子沿与第一旋转方向相反的第二旋转方向旋转期间，冷却剂泄漏再次被输送出储存器。
结合电机的描述所讨论的优点和细节不言而喻地同样适用于根据本发明的方法。
附图说明
下面将参照附图基于示例性实施例来讨论本发明。附图是示意图，其中：
图1示出了根据本发明的电机的透视截面图；
图2示出了图1中转子右端的放大图；
图3示出了密封装置的细节；以及
图4示出了根据本发明的车辆。
具体实施方式
图1的透视截面图中所示的电机1属于车辆的传动系。
电机1包括壳体2，定子3和转子4容纳在壳体2中，转子4可相对于定子3旋转并且具有转子轴23。转子轴23被圆柱形转子体24包围。电机1还包括具有冷却通道5的冷却装置，冷却剂可以流过该冷却通道，该冷却通道从入口7穿过壳体2延伸到出口6。
入口7和出口6经由冷却剂管线(未示出)连接到泵，使得冷却剂在回路中输送。冷却剂消散电机1运行期间产生的热量。
从图1中可以看出，冷却通道5从入口7开始延伸穿过壳体2。冷却剂通过冷却管25流入转子4的中空转子轴23。在冷却管25的端部，冷却剂的流动方向反向，随后冷却剂流出转子轴23，经过密封装置21(见图2),并向前流到出口6。
在壳体2的外部，布置有逆变器8，其提供电机1运行所需的AC电压。
图2示出了图1所示的转子轴23的右端的剖视图。密封装置21用于相对于壳体2在径向方向和轴向方向上密封转子轴23。特别地，密封装置21用于相对于容纳定子3的壳体2的内部空间22密封转子轴23。该密封防止冷却剂进入内部空间22并导致其中定子3的绕组腐蚀。
密封装置21包括滑环密封件9和径向轴密封环11。滑环密封件9沿轴向方向布置在转子轴23的自由端(在图2中的右侧)和壳体2的一部分之间。滑环密封件9轴向密封转子轴23。
转子轴23的所述端部被由硬化的高级钢构成的套筒10包围。套筒10又被径向轴密封环11包围，径向轴密封环11相对于壳体2的内部空间22径向密封转子轴23。
密封装置21具有这样的特性，即在被分配给电驱动车辆的反向行驶的电机的特定旋转方向上，发生上述技术泄漏。然而，所述技术泄漏仅涉及几毫升范围内的小体积。
在图2的截面图和图3的放大图中，示出了密封装置21的细节，可以看出，在滑环密封件9、径向轴密封环11和壳体2内部围绕密封件的部分之间形成环绕的自由空间。所述自由空间，更具体地说是其在电机1的安装状态下的下部区域，用作冷却剂泄漏的储存器12。如果由于电机1的运行而发生技术泄漏，特别是在反向行驶期间，所述泄漏收集在储存器12中。
在旋转方向反转的情况下，所述冷却剂泄漏经由密封装置21被供应回冷却剂回路。因此，如果转子4在与第一旋转方向相反的第二旋转方向上旋转，储存器12再次被排空。
滑环密封件9包括静态密封件13和环14，环14可与转子轴23一起旋转，并且具有特殊的表面结构。特别地，滑环密封件9可以配置为机械混合密封件。
已经收集在储存器12中的冷却剂泄漏借助于环14的表面结构经由密封装置21被再次输送或传导回到冷却剂回路中。
因此，在用于运行电机1的方法中，在转子4沿第一旋转方向旋转期间发生的冷却剂泄漏被收集在储存器12中，并且在转子4沿与第一旋转方向相反的第二旋转方向旋转期间，所述泄漏被再次输送出储存器12。
图4示出了具有包括电机1的传动系的车辆17。电机1经由齿轮箱18联接到车辆17的车轮19。电机1另外连接到逆变器8。存储在电池20中的能量被逆变器8转换成用于电机1运行的AC电压。
