Abstract

本发明涉及作为液压泵用于滑动控制的车辆制动装置的内齿轮泵(1)。本发明提出的是，将内齿轮泵(1)设计为具有被装入车辆制动装置的液压块的容纳部中的作为壳体(2)的筒(3)的预装配的组件。

Description

内齿轮泵
技术领域
本发明涉及一种具有权利要求1前序部分的特征的用于车辆液压制动系统的内齿轮泵。这种内齿轮泵代替通常使用的活塞泵应用在防滑控制的和/或外力的车辆制动系统中，并且常常，即使不是绝对恰当的，称为回输泵。
背景技术
内齿轮泵是已知的。它们具有齿圈和偏心地设置在该齿圈中的小齿轮，该小齿轮在一圆周段上与齿圈啮合。齿圈是内啮合的齿轮，小齿轮是外啮合的齿轮，齿圈和小齿轮也可理解为内齿轮泵的齿轮。称呼为小齿轮和描述为齿圈用于区分它们。与齿轮啮合所在的圆周段相对地有在齿圈和小齿轮之间的镰刀状的、这里被称作泵腔的自由腔。在泵腔内设置了分隔件，两个齿轮的齿顶在外部和内部贴靠在该分隔件上并且该分隔件将泵腔分为吸入腔和压力腔。分隔件由于其典型的形状也经常称为镰刀或镰刀件。对于分隔件的另一种称呼是填充件。通过旋转驱动，齿轮将液体从吸入腔供给到压力腔中。也已知没有分隔件的内齿轮泵，为了区分可称为齿环泵。
专利DE 196 13 833 B4公开了这样的自身具有壳体的内齿轮泵，通过该壳体它例如可法兰连接在用于驱动它的电机上。该内齿轮泵不是为车辆液压制动系统而设置的。
公开文献DE 10 2009 047 626 A1公开了一种用于车辆液压制动系统的内齿轮泵，它自身没有壳体而是被安装进车辆液压制动系统的防滑控制装置的液压块中。该液压块可理解为内齿轮泵的壳体。
这种液压块是已知的，其用于防滑控制装置的液压元件的机械固定和液压连接。这种元件除内齿轮泵之外是用于防滑控制的电磁阀和液压蓄能器。液压块通常是由金属、尤其由铝制成的方形零件，在该方形零件中设有圆柱形的且经常直径呈阶梯变化的沉孔作为用于防滑控制装置液压元件的容纳部并且设有将所述容纳部和安装在容纳部中的元件液压连通的孔。
发明内容
根据本发明的具有权利要求1特征的内齿轮泵设计为可预装配的组件并且具有筒作为壳体，该筒能够装入用于特别是在车辆液压制动系统防滑控制装置的液压块中的内齿轮泵的容纳部中。通过设计为组件，根据本发明的内齿轮泵能够如同一体的零件那样操作，这简化了其组装并且尤其简化了装入容纳部中。本发明的另一个优点是，可以在内齿轮泵预装配为组件之后且尚在装入到容纳部之前来检验该内齿轮泵的功能优异性和(压力)密封性。在批量生产中通常使用不允许扩装和重装的压入程序和填密程序。在错误情况下内齿轮泵是废品。若已将内齿轮泵装入液压块中，则在错误情况下不仅内齿轮泵而且装入有液压结构元件的液压块作为整体是废品。
筒应理解为内齿轮泵的壳体，该壳体设计为在外部与容纳部相对应，从而其能够准确匹配地装进容纳部中。
从属权利要求的对象是在权利要求1中说明的发明的有利设计方案和改进方案。
权利要求6给出了本发明一种优选的设计方案，其对象是根据本发明的具有两个内齿轮泵的双内齿轮泵，其中每个内齿轮泵设置用于双回路车辆液压制动系统的一个制动回路。两个内齿轮泵互相分开地被设置在环绕壳体的两个容纳部中并且具有共同的例如借助于齿轮的驱动装置。为了与设计为可预装配组件的内齿轮泵的壳体相区分，将具有用于两个内齿轮泵的两个容纳部的壳体称为环绕壳体。尤其液压块构成用于两个内齿轮泵的壳体或者说环绕壳体。
根据本发明的内齿轮泵尤其设置为用于液压的、防滑控制的和/或外力的车辆制动系统的液压泵，代替了通常使用的活塞泵。在防滑控制的车辆制动系统中液压泵也称为回输泵。如所述地，作为根据本发明的双内齿轮泵的优选实施方式设置用于为每个制动回路设有一个齿轮泵的双回路车辆制动系统。
附图说明
下面借助于在附图中所示的实施方式来详细阐释本发明。附图中：
图1以立体图示出了在根据本发明的内齿轮泵；
图2以相反的视线方向示出了图1中的内齿轮泵；
图3以立体图示出了具有两个用于图1和图2的两个内齿轮泵的容纳部的液压块；以及
图4示出了图3中的装入了根据本发明的内齿轮泵的液压块。
具体实施方式
图1和图2示出了根据本发明的用于车辆液压制动系统的内齿轮泵1。该内齿轮泵具有圆柱形的单侧敞开的壳体2，该壳体被构造为用于被装进还要阐释的容纳部中的筒。所述筒3在纵向中心具有环绕的凹槽，在本实施例中为O型圈的密封圈4嵌入该凹槽中。
在筒3的在图1中可见的敞开端部上，可以看到同轴地设置在筒3中且可转动地支承在其中的齿圈5和内齿轮泵1的偏心地设置在齿圈5中的与齿圈5啮合的小齿轮6。该小齿轮6是外啮合的齿轮并且齿圈5是内啮合的齿轮，为了区分将它们称作小齿轮6和齿圈5。在小齿轮6与齿圈5啮合的周向段之外，在筒3的敞开端部中可以看到在小齿轮6和齿圈5之间的镰刀形的、这里被称作泵腔7的自由腔的端部。泵腔7的可见端部是吸入腔8，在该吸入腔中内齿轮泵1吸入制动液。设置在泵腔7中的将泵腔7分为吸入腔8和在泵腔7另一端处的不可见的压力腔的分隔件在附图中是不可见的。通过旋转驱动，小齿轮6和齿圈5以本身已知的方式将制动液从吸入腔8供给到压力腔。
小齿轮6是不可相对旋转地位于泵轴9上，该泵轴通过筒3(其构成内齿轮泵1的壳体2)的封闭端部实施成密封的。如同在图2中可见，内齿轮泵1具有作为驱动轮10的齿轮，其外部地设置在筒3的封闭侧并且在那里被不可相对旋转地安装在泵轴9上。
在小齿轮6、齿圈5和在附图中不可见的设置在泵腔7中的分隔件的两侧设有轴向垫片11，其贴靠在小齿轮6、齿圈5和分隔件上。轴向垫片11是轴向可动且不可相对旋转的，它们覆盖不可见的压力腔和不可见的分隔件并且在吸入腔8的区域内省去。这种轴向垫片也称作压垫片或控制垫片或者压板或控制板。在背离小齿轮6、齿圈5和分隔件的外侧面中，轴向垫片11具有所谓的压力区12，该压力区由压力区密封件13所包围。压力区12指的是平的、在所示的实施例中为肾形的凹部，该凹部基本上在压力腔和分隔件上延伸。压力区12的压力加载将轴向垫片11加载成密封地紧贴到小齿轮6、齿圈5和分隔件上。压力区12具有通孔14，压力区通过该通孔与内齿轮泵1的压力腔相通。在图1中朝向观察者的轴向垫片11外露，即，其背向小齿轮6、齿圈5和分隔件的外侧面未被覆盖，在该实施方式中它大约齐平地与构成内齿轮泵1壳体2的筒3的敞开端部位于一个平面中。
内齿轮泵1预装配为在构成内齿轮泵1壳体2的筒3中的组件。通过预装配为组件，内齿轮泵1能够如同一体的部件那样操作和装入，此外作为组件预装配的内齿轮泵1在其装入前的有效性检测和密封性检测是可能的。
图3示出了车辆液压制动系统的其余未示出的防滑控制装置的液压块15。液压块15是用铝制成的块状零件，在该块状零件中设置有沉孔作为防滑控制装置液压元件的容纳部。液压块15尤其具有用于两个在图1和图2中示出的内齿轮泵1及用于未示出的电磁阀和液压蓄能器的容纳部16。可见的是在图1中还有两个沉孔作为未示出的双回路主制动缸的接口17。其他的容纳部位于附图中液压块15的下侧并且因此是不可见的。
液压块15具有用于两个内齿轮泵1的两个容纳部16，所述容纳部被实施为与筒3相符的圆柱形沉孔，内齿轮泵1如在图4中可见地可准确匹配地插入到该沉孔中。在装入时，筒3的敞开侧与外露的轴向垫片11朝向容纳部16的底部，驱动轮10位于容纳部16的敞开侧中，从而如图4中可见地驱动轮是可触及的。在筒3的凹槽中的密封圈4将在液压块15的容纳部16中的内齿轮泵1密封。外露的轴向垫片11位于容纳部16的底部上，压力区密封件13密封地贴靠在容纳部16的底部上。在用于内齿轮泵1的容纳部16的底部中通入压力连接孔18和吸入连接孔19。压力连接孔18通入到在筒3(其构成内齿轮泵1的壳体2)的敞开侧中的外露轴向垫片11的压力区12中。通过压力区12和在轴向垫片11中的通孔14，内齿轮泵1的压力腔与相应的压力连接孔18相通，该压力连接孔与压力区12共同地通过压力区密封件13密封。
吸入连接孔19通入从轴向垫片11空出的区域中，从而吸入连接孔19与内齿轮泵1的吸入腔8相通。通过这种方式，内齿轮泵1的吸入接口和压力接口连同接口的密封在内通过将内齿轮泵1安装到液压块15的容纳部16中而实现。液压块15构成两个内齿轮泵1的壳体并且这里为了与同样构成内齿轮泵1的壳体2的筒3相区分而被称作环绕壳体。在构成环绕壳体的液压块15中容纳了两个作为组件预装配的内齿轮泵1以及它们的构成它们壳体2的筒3。例如通过填密将内齿轮泵1固定在容纳部16中。
两个内齿轮泵1共同地用电机20来驱动，在该电机上法兰连接有传动机构。电机20可放置到装入了两个内齿轮泵1的容纳部16上并且例如可与液压决15螺纹连接。电机20具有这里被称作主动轮21的齿轮，若电机20固定在液压块15上，则该主动轮位于两个内齿轮泵1的驱动轮10之间并且与两个驱动轮10啮合。为了定位，电机20在主动轮21两侧具有两个突起部，所述突起部相称于用于内齿轮泵1的容纳部16的通入口，并且在驱动轮10上方准确匹配地接合到容纳部16中。突起部22构造在用于将电机20固定在液压块15上的电机20的法兰盘23上。替代地，定位可以通过未示出的同轴地围绕主动轮21的或者位于主动轮21后方的直径来实现，该直径准确匹配地接合到液压块15的中心孔中。
