Description
技术领域
本发明基于具有电驱动器的泵,其中电驱动器安装在泵的法兰上并且沿电动机轴的方向具有电接触部。
背景技术
辅助设备真空泵在机动车中用于用例如绝对100毫巴和更低的负压和/或过压供给其他的设备、例如制动力放大器。为了在提供过压或负压时是与机动车驱动电动机的、例如内燃机的转速无关的,使用电动机驱动的真空泵,所述真空泵通常构成为具有至少三个转子叶片的叶片泵。
为了节省润滑剂供应并且为了避免离开真空泵的空气的污染,使用干式叶片泵。由于取消干式真空泵的润滑,对真空泵的材料配对即转子叶片/冲程环提出高的要求。
从EP2570673中已知一种电的机动车真空泵,所述机动车真空泵具有电动机模块和上面装有法兰的泵模块。电动机模块具有定子侧的电动机线圈和承载电动机转子的电动机轴。电动机轴通过固定滚动轴承和浮动滚动轴承支承在电动机模块的壳体上。在此,泵模块是具有能活动地支承的泵转子轴的干式旋转滑阀泵模块。因此,泵转子轴不具有自身的轴承,而是作为电动机轴的刚性的延长部伸入泵模块中。泵转子轴间接地或直接地保持多个旋转滑阀,其将旋转的泵室沿环周方向限界并且彼此分离。
电动机必须接触。接触部径向于电动机/泵轴的引出在多个可从市场中购买的电动机中实现。在此,与电动机的插接必须经受持续60秒时间的160N的力而不被损坏。
发明内容
因此,本发明的目的是,安装一种泵,其电接触部是抗拉的并且还能相对于大气密封。
所述目的借助于具有电动机的泵来实现,其中电动机借助于法兰安装在泵上并且在电动机的端侧上具有电接触部并且电动机用引导盖覆盖,所述引导盖具有从电接触部直至输出开口的槽以铺设线缆,并且其中槽进行至少一次径向的方向变换并且引导盖的环绕的边缘借助于输出开口的密封件将电动机相对于泵的法兰盖密封。
根据本发明的引导盖的优点是,不仅线缆的应力消除还有电动机相对于外部影响的密封是可能的。由此,节省耗费的密封***。
在此,还有利的是,引导盖由塑料材料构成。通过适当地选择塑料材料,得到在电动机和泵壳体之间的充分的密封作用。此外,能够以简单的方式和方法并且成本低地制造构件。
在此,有利的是,引导盖具有用于电动机的电接触部以及电动机轴的至少一个留空部。
对于安装泵有利的是,将引导盖由泵的法兰盖包围。由此,确保两个组件相对于彼此的简单的检查,并且结构高度保持为小。在此,引导盖有利地具有至少对应于当前的线缆的厚度的结构高度。
一个有利的实施方式应用关于穿过接触部和输出开口的中轴线镜面对称的槽伸展部。然而,不具有镜面对称性的实施方式也是可能的。
附图说明
在下文中,示例地参照附图描述本发明。
图1示出示例的实施方式的示意图。
图2示出根据本发明的应力消除装置的俯视图。
图3示出一个替选的实施方式。
具体实施方式
图1示意地示出电动机1的根据本发明的解决方案的构造。所应用的电动机具有极叉2,所述极叉从其端侧的覆盖件平行于在图中未示出的电动机轴伸出。此外,电动机具有安装在固定螺栓孔4中的环绕的法兰3。电动机1经由法兰盖5与同样未示出的泵壳体连接。在此,在电动机1和法兰盖5之间应当没有气体或气体混合物如空气或液体渗入到组件中。法兰盖具有能够将法兰盖借助于螺栓连接件固定在上面的设备。在现有技术中,两个构件相对于彼此的密封借助于环绕的密封条或模制密封件实现。
在图1中示出具有引导盖6的根据本发明的解决方案。引导盖6是塑料压铸构件,所述塑料压铸构件在其外直径上匹配于电动机1和具有法兰盖5的泵壳体。法兰盖构成为搭接盖并且包围引导盖,其中在边缘上设有槽,线缆从所述槽中引出。
引导盖6具有第一留空部7,所述第一留空部容纳发电机1的极叉2。在中心设有第二留空部9,所述第二留空部包围电动机的轴。在引导盖的由此构成为平坦的宽的环的结构之内引入槽10,所述槽具有垂直于极叉2的第一伸展区域11和随后的第二伸展区域12,在第二伸展区域中槽10从外直径向内折弯地伸展,以及向外直径靠近的第三伸展区域13。在第四伸展区域14中,槽通到输出开口15,所述输出开口构成为在引导盖6的环绕的边缘16中的穿通部。
在安装和接触电动机时,将极叉2与线缆的端部17连接,这有利地借助于焊接,然而也借助于机械的卷曲(Verkrimpen)或拧紧进行。
紧接着,将线缆铺设在槽中并且穿过输出开口15向外引导。在输出开口中引入适合的密封剂,或者将输出开口用硅树脂密封地封闭。施加并且拧紧法兰盖。由此,密封电动机1。
焊接或其他在电动机的极叉上的连接不受到负荷直至达到断裂极限,因为在引导盖6的槽10中的曲折引导部的几何形状用于,将牵引力转换为表面压力和静摩擦。在图2中还标出示出槽的和引导盖的支撑功能的箭头。
电动机的密封经由引导盖的边缘16和用于线缆的输出开口15的密封来进行。
在此,能够任意地构成槽的形状,以便接收在线缆上的牵引力。在图3中示出一个替选的实施方式。
引导盖同样具有带有不同区域的槽。以用于极叉的留空部17为出发点,第一区域11从左侧随着凹部从引导盖的边缘向内伸展。
随后,第二区域近似平行于引导盖的外半径,在此之后是第三区域中的另一凹部。
在此,在所述示例中,装置不是关于具有极叉的留空部7对称的。仅考虑的是,通过在槽的伸展中的方向变换将力传输到引导盖上并且将与极叉的连接部位消除应力。
在引导盖6中的留空部的位置通过总是设置在中心的电动机轴给出。电接触部例如极靴2优选设置在电动机的边缘上。为了确保最优地消除接触部的牵引力有意义的是,选择电接触部与线缆的输出开口在直径上相对置的设置方式。
