Description

机动车真空泵装置
本发明涉及一种电气式机动车真空泵装置,其具有带有进气口装置和排气口装置的复合壳体,所述复合壳体具有泵机组和驱动马达,其中,所述泵机组具有由进气侧和排气侧的端壁和布置在其间的泵转子壳体件构成的泵转子壳体,所述端壁和泵转子壳体件包围泵转子室,在所述泵转子室中设有泵转子,其中,所述驱动马达具有马达转子和马达定子,其中,设有用于降低噪音的消声件,其中,所述消声件具有至少两个依次连接的消声空间,其中,第一消声空间通过第一连接装置与所述泵转子室流体连接并且通过第二连接装置与第二消声空间流体连接,并且其中,第二消声空间与排气口装置流体连接。
电气驱动的机动车真空泵与内燃机的运行状态无关地在机动车中产生例如100毫巴的绝对负压,该负压例如需要用于运行气动的制动助力器和/或其它的气动运行的辅助设备。在电气式机动车真空泵装置中,驱动马达的电气功率在小真空泵的情况下典型地处于100W的范围内并且在大真空泵的情况下是几百瓦。根据泵机组的泵功率和转速,噪音可能大到,使得必须实施全面的措施用于消声和/或屏蔽声音。为此的一个例子在专利文献WO2014/135202 A1中描述。但该电气真空泵的构造由于所使用的消声件耗费非常大并且导致相对大的结构空间。
因此,本发明所要解决的技术问题在于,提供一种具有低噪音的电气式机动车真空泵装置,该机动车真空泵装置以简单且低成本的方式避免上述缺点。
所述技术问题按照本发明解决的方式是,设置至少一个穿孔装置形式的用于第二连接装置和/或排气口装置的消声件。业已证明,通过这种简单的措施可以显著减少出现的噪音。由此,真空泵需要更小的结构空间并且能够成本更低地制造。
在特别有利的实施方式中,第一消声空间集成在排气侧的端壁中。此外,第一连接装置由具有止回阀的第一泵出口和沿泵转子的转动方向观察错位布置的第二泵出口构成。
有利地,第一消声空间由布置在排气侧的端壁的背离泵转子的一侧上的盖元件建立,其中,第二连接装置设计为排气侧的端壁中的槽。
在特别有利的、有利于结构空间的实施方式中,复合壳体具有端盖元件,所述端盖元件抓握排气侧的端壁,使得构造有第二消声空间。
排气口装置作为连续的穿孔元件形式的穿孔装置设置在排气侧的端壁、泵转子壳体件和进气侧的端壁中,由此,已有的壳体部件可以被用于排气口并且通过穿孔装置的反射性质确保显著的减少噪音。噪音还可以通过如下方式改善,即,进气侧的端壁中的穿孔元件朝向排气侧扩宽。
有利地,泵机组与驱动马达同轴布置,其中,驱动转子的转子轴通过支承件支承在进气侧的端壁中。
此外,有利于结构空间的是,进气口装置设置在进气侧的端壁中。
原则上,旋转式泵机组的所有型号都适合。特别优选地,泵机组是叶片式泵机组。
以下根据附图详细阐述本发明。在附图中:
图1示出按照本发明的电气式机动车真空泵装置的立体视图,和
图2示出图1中的机动车真空泵装置的泵机组和驱动马达的部分的剖视图。
在图1和图2中示出电气式机动车真空泵装置2,其在机动车中用于提供具有例如100mbar和更小的绝对压力的真空。真空主要用作用于致动器、例如气动的制动助力器或其它气动的机动车致动器的潜在能量。用于机动车真空泵的电气驱动装置变得越来越多地需要,因为机动车内燃发动机在车辆运行期间不持续运转。
机动车真空泵装置2基本上由复合壳体4构成,复合壳体4具有驱动马达6和泵机组8。驱动马达6在此设置在罐形的马达壳体10中并且以已知的方式具有驱动转子12(为此参见图2)和未进一步示出的驱动马达定子。泵机组8具有泵转子壳体14,泵转子壳体14由进气侧和排气侧的端壁16、18和布置在进气侧和排气侧的端壁16、18之间的泵转子壳体件20构成(此处尤其参见图2)。复合壳体4此外具有端盖元件22,端盖元件22抓握排气侧的端壁18和泵转子壳体件20并且在进气侧的端壁16上形状接合地接合。具有端盖元件22的转子壳体14通过第一凸缘件24与罐形的驱动马达壳体10连接。第一凸缘件24又在中间连接有减震体26的情况下与第二凸缘件28连接,通过第二凸缘件28可以将机动车真空泵装置2与机动车的车身构件连接。
另外,图1示出塑料管元件形式的进气口装置30,该塑料管元件设置在进气侧的端壁16中,并且有待从机动车致动器排出的空气通过进气口装置30导引入泵机组8中。用32标注排气口装置,由泵机组8压缩的空气从排气口装置排入环境中。
在此,图2示出泵机组8以及驱动马达6的部分的剖视图。如前所示,驱动马达6具有抗扭地固定在驱动转子轴34上的驱动转子12,其中,驱动转子轴34同时用作用于设置在泵转子壳体14的泵转子室35中的泵转子36的转子轴。驱动转子轴34在此通过设计为滚动轴承的支承件38支承在进气侧的端壁16中。
为了良好的秩序应当注意的是,用40标注用于给驱动马达6供电的电气的连接电缆。通过进气口装置30吸入的并且在转子室35中由设计为叶片转子的泵转子36压缩的空气通过第一连接装置42从转子室35排出。第一连接装置42在此以已知的方式由为降低噪音具有止回阀46的第一泵出口44和沿泵转子36的转动方向错位布置的第二泵出口48构成。压缩空气经由第一连接装置42到达集成在排气侧的端壁18中的第一消声空间50中。为此,第一消声空间50在排气侧的端壁18的背离泵转子36的一侧上具有盖元件52。通过盖元件52也建立第二连接装置54,第二连接装置54基本上设计为排气侧的端壁18中的槽56。压缩的、在第一消声空间50中消声的空气经由第二连接装置54被输送至第二消声空间58中。第二消声空间58建立的方式基本上是,端盖元件22流体密封地抓握排气侧的端壁18。压缩空气则通过设计为穿孔装置60的排气口装置32被排放到环境中。在此,穿孔装置60由连续的穿孔元件62、64和66构造。穿孔元件62设置在排气侧的端壁18中,穿孔元件64设置在泵转子壳体件20中,并且穿孔元件66设置在进气侧的端壁16中。以此方式,穿孔装置60形成长条形的管元件,由此又可以实现附加地减弱空气声。此外,穿孔元件66朝向排气侧扩宽,由此,基于压力变化再次降低噪音。
应当清楚的是,视电气式机动车真空泵装置2的结构形式而定,第二连接装置54也可以附加或单独地设计为穿孔装置。
