附图说明
包含于说明书中并且形成说明书的一部分的附图示例说明本发明的优选实施例,并且与描述一起用来解释说明本发明的原理。
图1为图2的泵的横截面A-A。
图2为泵的平面图。
图3为泵的平面图。
图4为示意性的冷却系统。
图5为分解图。
图6为转子磁体和框架的立体图。
具体实施方式
图1为图2的泵的横截面A-A。水泵包括驱动叶轮的电动马达。电动马达包括轴向磁通马达。在轴向磁通马达中,由于极和定子绕组的取向,磁通量沿轴向方向在马达的空气间隙中延伸。本发明的水泵通常被用于发动机冷却系统中。所述水泵通过发动机冷却系统使冷却剂加压并且循环。
水泵1000包括壳体10和盖50。叶轮150附接至转子轴100的端部。定子200设置于壳体内。多个定子极201以环的形式设置于壳体10的内部部分11内。与轴向磁通马达的情况一样,每个极201的轴线B-B平行于轴100的旋转轴线D-D。马达包括三相九线圈架构。定子极201包括软金属复合材料。磁性材料也可以被用于定子极201。
电线绕组202围绕每个极201缠绕。绕组202在横截面上可以包括扁平线或圆线。扁平线可以具有正方形或长方形横截面。扁平线或圆线可以包括铜或铝。绕组202的绕组平面C-C正交于轴的轴线D-D延伸,因此磁通量平行于轴线D-D沿轴向方向延伸。本发明的马达具有200W并且最高至12kW的额定功率。
多个永磁体110在框架115上安装至轴100的另一个端部。磁体110还可以包括具有多个极的单个环形磁体。框架115固定至轴100的端部并且从而与轴100一起旋转。磁体110与极201径向地对准。在极201与磁体110之间维持空气间隙“G”,从而在操作期间防止它们之间的接触。空气间隙在0.2mm至1.5mm的范围内。间隙“G”优选地尽可能小以实现最大的磁效率。
机械密封件250防止加压的液体冷却剂进入内部部分11并且由此与定子200和转子磁体110接触,因此,定子200和磁体110处于干区域中。所述干区域通常处于环境大气压。密封件250设置于轴100与壳体10之间。密封件250可以包括本领域中已知的任何合适的机械密封件,比如波纹管、筒、平衡筒与O形环、非平衡筒与O形环、推进器、以及常规类型的密封件。为定子和磁体维持干燥的空间通过减少风阻和粘滞损失而提高了泵的效率,所述风阻和粘滞损失在内部部分11包含冷却剂并且冷却剂由此存在于定子极与转子磁体之间的间隙“G”时出现。
冷凝室和储存器301包括通气孔302和排放孔303。室301收集可能泄漏通过密封件250的任何流体。通气孔302和排放孔303向外界打开。
热灌封12用在壳体10中以包裹定子200。热灌封通过提供从定子和壳体的可靠的热传递方式而使泵更冷地运行。通常由于铁和铜损耗以及由变化的磁场在定子和绕组中感应的涡电流所引起的电阻加热而发生泵加热,所述电阻加热从被泵送的冷却流体以及从发动机机体(未示出)传导至壳体。热灌封在电气领域中是已知的。
转子轴100在单个轴承120中旋转。轴承120还可以包括整体式轴承,其中轴100包括轴承内圈。旋转的组件包括轴100、框架115、磁体110以及叶轮150。单个轴承120可以包括双列滚珠轴承或双列滚珠-滚柱轴承。滚柱轴承可以包括圆柱形滚柱或锥形滚柱。由于轴向磁通马达构造所提供的泵轴的长度较短,所以可以使用单个轴承。轴承包括密封轴承。由于泵轴100的总长度较短,所以叶轮150悬臂安装至轴100。
当叶轮旋转时,冷却剂流动至叶轮入口151中并且被从出口152排出。叶轮在水泵领域中是已知的。通常的工作排出压力可以高达大约1.5巴,但是可以根据发动机的热负荷而变化为超过5巴。根据应用,流量可以高达每分钟220升、或更高地高达每分钟500升。
动力电子设备设置于盖50中的电子设备壳体51中。动力电子设备控制轴的旋转速度并且还可以检测故障。轴向磁通马达动力电子设备在本领域中为已知的。盖50充当散热器以冷却动力电子设备。马达为变速的,这容许根据发动机的热负荷要求来调节冷却流体流量。控制方法包括PWM、LIN协议/总线或CAN协议/总线。LIN总线为基于串行通信协议的子总线系统。总线为使用单个线来传输数据的单个主总线/多个从总线。控制器局域网或CAN协议为各种电子装置之间的通信方法,所述各种电子装置如发动机管理系统、水泵、油泵、主动悬架、ABS、传动控制装置(gear control)、照明控制装置、空调、安全气囊、嵌入于汽车中的中控锁。PWM或脉冲宽度调制为一种数字信号,所述数字信号被用于包含控制电路的各种应用中。
图2为泵的平面图。排放蜗壳13与发动机机体(未示出)中的配合通道接合。壳体10被直接地安装至发动机机体。抽吸侧或吸入侧150配合地接合发动机中的流体导管(未示出)。
图3为泵的平面图。紧固件(未示出)与安装孔14接合以将泵附接至安装表面,所述安装表面比如为发动机机体(未示出)。
图4为示意性的冷却系统。泵1000被安装至发动机(E)。发动机(E)包括三个气缸(1)、(2)、(3)。发动机(E)可以根据需要包括任何数量的气缸。水套(J)包围气缸。所述系统进一步包括散热器(R)、发动机变速器油热交换器(OC)、辅助热交换器(AUX)以及排气歧管热交换器(EM)。
热管理模块2000被安装至泵1000的吸入侧。模块2000包括多个阀2001、2002、2003、2004、2005以及2006。每个阀控制系统部件的冷却剂流量。阀2001控制至散热器R的流量。阀2002控制至热交换器OC的流量。阀2003控制至热交换器AUX的流量。阀2004控制来自R、OC、AUX以及EM的返回流量。阀2005控制来自泵1000的再循环流量以及至EM的流量。阀2006控制来自E、EM、AUX、OC以及R的返回流量。发动机ECU通过多个传感器和输入信号(3001)检测发动机和系统的状况、环境状况以及系统和驾驶员的请求以将每个阀设定在所需的位置中以调节冷却剂流量,并且由此控制发动机和系统的热性能。每个阀都与泵入口151流体连通。
图5为分解图。马达为三相马达。绕组202(a)为第一相。绕组202(b)为第二相。绕组202(c)为第三相。在该实施例中,每个相包括三个定子极。然而,也可以使用连接至单个相或多个相的各个极的绕组。垫圈15在壳体10与发动机E之间密封。
图6为转子磁体和框架的立体图。磁体220安装至框架115。框架115被压至轴100上。框架115还可以包括叶片部以使冷却空气循环。
磁体110可以包括具有围绕圆周的极的环形磁体,或者可以包括具有在交替位置中的极的多个单独的磁体。磁体可以包括铁氧体、稀土或其它已知的材料。使用已知的方法将磁体附接至框架。
