Description
技术领域
本发明涉及一种具有权利要求1的前序部分所述的特征的内齿轮泵。代替通常使用的活塞泵,这种内齿轮泵应用在防滑调节的和/或外力辅助的车辆制动设备中,并且常常并非绝对准确地也被称为回油泵。
背景技术
内齿轮泵是已知的。其具有小齿轮,即外啮合的齿轮,该外啮合的齿轮偏心地布置在内啮合的齿圈中并且在圆周的部位上或者在圆周区段中与齿圈啮合。小齿轮和齿圈也可理解成内齿轮泵的齿轮。通过两个齿轮中的一个、通常是小齿轮的旋转驱动,也旋转地带动驱动另一齿轮、即通常为齿圈,并且内齿轮泵以已知的方式输送流体,其在车辆液压制动设备中输送制动液。
与小齿轮与齿圈在其中啮合的圆周区段相对地,内齿轮泵在小齿轮和齿圈之间具有镰刀形的自由空间,该自由空间在此被称为泵腔。在泵腔中设有分隔件,该分隔件将泵腔分成吸入区域和压力区域。分隔件由于其典型的形状也被称为镰刀部或镰刀形件,另一名称是填充件。分隔件的典型的空心圆形的内侧贴靠在小齿轮的齿的齿顶上并且分隔件的典型的向外弯曲的外侧贴靠在齿圈的齿的齿顶上,从而分隔件包围在内齿轮泵的齿轮的齿之间的齿隙中的流体体积。通过旋转驱动,齿轮将齿隙中的流体从吸入侧输送到压力侧。
公开文献DE 10 2009 047 643 A1公开了这种类型的内齿轮泵,其分隔件是多件式的并且具有其内侧贴靠在小齿轮的齿的齿顶上的内侧件以及其外侧贴靠在齿圈的齿的齿顶上的外侧件。以克服在压力区域中的压力的方式,已知的内齿轮泵的分隔件的内侧件和外侧件在周向上支撑在栓上,该栓形成支座。形成支座的栓布置在分隔件的吸入侧上并且横向地或轴线平行地穿过泵腔。
发明内容
根据本发明的具有权利要求1所述的特征的内齿轮泵具有多件式的分隔件,该分隔件具有贴靠在小齿轮的齿的齿顶上的内侧件以及贴靠在齿圈的齿的齿顶上的外侧件。根据本发明,分隔件的内侧件和外侧件以在径向方向上可运动的方式相互连接。“径向”与以下使用的术语“圆周侧”、“周向”和“轴向”同样地针对内齿轮泵和部件的规定的安装位置。不排除内侧件和外侧件在与径向方向不同的方向上的可运动性。内侧件和外侧件在内齿轮泵的径向方向上的可运动性可实现内侧件和外侧件规定地贴靠在内齿轮泵的齿轮的齿的齿顶上。内侧件与外侧件的连接实现了将多件式的分隔件作为一个部件操作并且简化了内齿轮泵的装配。
从属权利要求的对象包括在权利要求1中给出的本发明技术方案的有利的设计方案和改进方案。
权利要求2规定,为了在径向方向上可运动的连接,内侧件和外侧件在径向方向上以具有间隙的方式彼此在后部接合。根据权利要求3的改进方案规定,外侧件在圆周侧的端部上包围内侧件,或者相反。本发明的这些设计方案在没有附加构件的情况下实现了分隔件的内侧件和外侧件的简单的在径向方向上可运动的连接。
权利要求4规定,内侧件在周向上支撑在外侧件上。这意味着,内侧件贴靠在外侧件上,这简化了在内侧件和外侧件之间的密封。权利要求4也包括相反的情况,也就是说,外侧件在周向上支撑在内侧件上。优选地,分隔件的两个部件中的仅仅一个部件在周向上直接支撑在内齿轮泵的支座上,另一部件间接地通过所述一个部件支撑在支座上。
权利要求7规定了分隔件的构件作为可预装配的组件的构造方案,该组件在其预装配之后如一个构件那样可被***在内齿轮泵的齿轮之间的泵腔中。
根据本发明的内齿轮泵特别是设置成用于液压的防滑调节的和/或外力辅助的车辆制动设备的液压泵。在防滑调节的车辆制动设备中,液压泵也被称为回油泵并且目前主要实施成活塞泵。
附图说明
下面根据在附图中示出的实施方式详细解释本发明。唯一的附图以正视图示出了根据本发明的内齿轮泵。
具体实施方式
在附图中示出的根据本发明的内齿轮泵1具有外啮合的在此被称为小齿轮2的齿轮和内啮合的在此被称为齿圈3的齿轮。小齿轮2轴线平行地且偏心地布置在齿圈3中,使得小齿轮2与齿圈3啮合。小齿轮2以防止相对旋转的方式布置在泵轴4上,通过该泵轴4能够旋转地驱动小齿轮2并且通过小齿轮2旋转地驱动与其啮合的齿圈3。以箭头P指出旋转方向。齿圈3可旋转地滑动支承在轴承环5中。
与小齿轮2与齿圈3在其中啮合的圆周区段相对地,内齿轮泵1具有镰刀形的自由空间,该自由空间在此被称为泵腔6。在泵腔6中布置有同样为镰刀形的或半镰刀形的多件式的分隔件7,该分隔件将泵腔6分成吸入区域8和压力区域9。吸入区域8与泵进口10相通,该泵进口10实施成孔并且横向地、也就是说相对于内齿轮泵1轴线平行地从一侧通入泵腔6的吸入区域8中。压力区域9与泵出口11相通,在该实施方式中该泵出口11实施成弧形的槽并且从一侧通入泵腔6的压力区域9中。弧形的泵出口11部分地与分隔件7重叠并且在周向上一部分超过分隔件7的压力侧的端部伸入泵腔6的压力区域9中。
多件式的分隔件7具有弧形的内侧件12和同样弧形的且卡箍形的外侧件13。内侧件12的凹形的且圆筒形的内侧贴靠在小齿轮2的齿的齿顶上,并且外侧件13的凸形的圆柱形的外侧贴靠在齿圈3的齿的齿顶上。通过贴靠在小齿轮2和齿圈3的齿顶上,分隔件7的内侧件12和外侧件13包围在小齿轮2和齿圈3的齿之间的齿隙中的流体,由此,在小齿轮2和齿圈3被旋转驱动时,将流体从吸入区域8输送到压力区域9。在内齿轮泵1规定地用作车辆液压制动设备的液压泵的情况中,被输送的流体为制动液。
在圆周侧的端部上,外侧件13包围内侧件12,使得形成在后部接合部,其以在径向方向上的间隙使内侧件12与外侧件13相连接。通过在后部接合部相互连接的并且在端部上被外侧件13包围的内侧件12可在径向方向上彼此相对地运动。
在内侧件12和外侧件13之间的间隙中设有板簧14,该板簧使内侧件12和外侧件13彼此压开并且由此如所设计的那样压靠到小齿轮2和齿圈3的齿的齿顶上。为了引起弹簧力,板簧14在未变形的状态中可以是平的,以与内侧件12和外侧件13不同的曲率弯曲的或者是波形的。所例举的并不是穷举的。
在压力区域侧的端部上,内侧件12和外侧件13之间的间隙(板簧14布置在该间隙中)与压力区域9相通,从而在内侧件12和外侧件13之间的间隙中存在与在压力区域9中相同的压力。该压力同样将分隔件7的内侧件12和外侧件13彼此压开并且压靠在小齿轮2和齿圈3的齿的齿顶上。
在吸入区域侧的端部上,密封元件15布置在分隔件7的内侧件12和外侧件13之间,该密封元件在内侧件12和外侧件13之间密封并且轴向地在泵壳体的未绘出的端壁或侧壁上或在内齿轮泵1的侧向限定泵腔6的所谓的轴向盘上密封。在所示出的实施方式中,密封元件15在未变形的状态中是圆柱形的。密封元件的其它形状也是可行的。
分隔件7的外侧件13在周向上以克服在压力区域9中存在的压力的方式支撑在支座16上,该支座16布置在分隔件7的吸入区域侧的端部上。在所示出的实施方式中,支座16是带有削平部17的柱形栓,分隔件7的外侧件13的吸入区域侧的端部贴靠在该削平部17上。形成支座16的栓在吸入区域6中横向地、也就是说轴线平行地穿过内齿轮泵1的泵腔6。
分隔件7的内侧件12不是直接支撑在支座16上,而是间接地通过外侧件13支撑。内侧件12的吸入区域侧的端部贴靠在外侧件13的包围所述端部的吸入区域侧的端部上。内侧件12在外侧件13上的贴靠简化了在内侧件12和外侧件13之间的密封,为此,简单的密封件、例如圆柱形的密封元件15是足够的。不需要高成本的、复杂的或多件式的密封。
外侧件13的包围内侧件12的端部的端部引起所描述的具有间隙的在后部接合部,该在后部接合部使内侧件12在内齿轮泵1的径向方向上可运动地与外侧件13相连接。布置在内侧件12和外侧件13之间的将内侧件12和外侧件13彼此压开的板簧14引起摩擦,该摩擦在轴向上或在侧向方向上将内侧件12保持在外侧件13中。分隔件7的部件,即内侧件12、外侧件13、板簧14和密封元件15形成组件,该组件可在内齿轮泵1之外进行预装配。在装配内齿轮泵1时,构造成组件的分隔件7作为一个构件被***在小齿轮2和齿圈3之间的泵腔6中,为此,只须径向地将内侧件12和外侧件13彼此压在一起,使得其间距不大于在小齿轮2和齿圈3的齿的齿顶之间的间隙。由此简化了在内齿轮泵1中的分隔件7的装配,这在小的构件中具有明显的优点,如在内齿轮泵1用作车辆液压制动设备的液压泵时是这种情况。
根据本发明的内齿轮泵1设置成未示出的液压的防滑调节的和/或外力辅助的车辆制动设备的液压泵,在此,其用于防滑调节、例如制动防抱死、驱动防滑和/或行驶动态调节和/或用于在液压的外力辅助车辆制动设备中产生制动压力。这种液压泵并非绝对准确地也被称为回油泵。对于所述防滑调节,其通常缩写成ABS、ASR、FDR和ESP。行驶动态调节在口头上也被称为防滑保护调节。
