Description

滑动调节装置的液压总成
技术领域
本发明涉及一种具有权利要求1的前序部分所述特征的、液压的车辆制动设备的制动调节器的液压总成。滑动调节装置例如是制动防抱死装置，驱动防滑装置和行驶动力调节装置或电子稳定程序，其缩写分别是ABS、ASR、FDR和ESP。
背景技术
公开文献DE 10 2006 059 924 A1公开了一种液压的车辆制动设备的滑动调节装置的液压总成的液压块。已知的液压块是由金属制成的立方体状的闸块(Klotz)，该闸块设有用于电磁阀、液压泵、压力传感器的容纳部以及用于安装来自主制动缸的或通到液压的车轮制动器的制动管路的接头。已知的液压块的两个较大的侧面其中之一用于安装用于驱动液压泵的电动机。所述电动机的电连接线路从用于安装电动机的侧面出发穿过贯通孔到达液压块的对置的侧面并且在那里触点接通。
发明内容
根据本发明的、具有权利要求1所述的特征的液压总成用于液压的车辆制动设备的滑动调节。根据本发明的液压总成具有尤其是立方体状的液压块和电动机，所述电动机布置在液压块的一侧面上，该侧面在以下也被称为液压块的马达侧面。所述电动机用于驱动一个或多个液压泵，这些液压泵布置在液压块中以用于产生制动压力和/或输送制动液。液压块具有从马达侧面直到对置的侧面的贯通孔，在贯通孔中布置用于电动机的电连接线路。该连接线路用于供电以便驱动电动机、控制装置，例如电动机的电子换向器，以及供电以便将例如电动机的转速传感器或角度传感器的信号传输给滑动调节装置的电子控制器。优选地，电动机的多个或所有的连接线路被引导穿过液压块中的贯通孔。液压块也可具有多个用于电动机的连接线路的贯通孔，从而例如用于给电动机的供电的连接线路能够与数据线路、信号线路和/或控制线路分开地从马达侧面被引导穿过液压块直到对置的侧面。根据本发明，在液压块中的贯通孔中密封用于电动机的连接线路，以便防止意外地到达电动机中或到达液压块的马达侧面上的制动液穿过贯通孔到达液压块的对置的侧面，其中连接线路布置在所述贯通孔中。这种密封也防止了，例如电动机的机械换向器的磨粒或用于为电动机的转子供电的滑环的磨粒穿过液压块中的贯通孔到达液压块的对置的侧面，用于电动机的连接线路布置在所述贯通孔中。
根据本发明的液压总成也可以用作用于产生和/或调节制动压力的助力制动压力总成，和/或被用于助力制动器的车轮制动压力所使用，其中，制动压力由液压总成产生而并非通过车辆驾驶员的肌肉力产生。助力制动压力总成可具有或者不具有滑动调节装置。
液压块用于机械地固定并且液压地连接滑动调节装置的结构元件。这种结构元件例如是电动机，液压泵，电磁阀，止回阀，液压蓄能器、减振器和压力传感器。液压块具有用于固定结构元件的容纳部并且设有孔，该孔可被称为液压块的钻孔并且使滑动调节装置的结构元件根据滑动调节装置的液压线路图相连接。如果配备有滑动调节装置的结构元件，则液压块形成液压总成。
从属权利要求的主题是在独立权利要求中给出的本发明的改进方案和有利的设计方案。
权利要求2规定，用于电动机的连接线路布置在空心轴中，所述空心轴使连接线路电绝缘和/或保护其不受损坏。空心轴可布置在电动机上，并且在电动机安装在液压块上时被装入到液压块中的贯通孔中。连接线路被密封在空心轴中并且空心轴被密封在液压块的贯通孔中。
权利要求3规定了用于在空心轴中和/或液压块的贯通孔中密封连接线路的密封环，和/或用于在液压块的贯通孔中密封空心轴的密封环。
用于在液压块的贯通孔中和/或空心轴中密封用于电动机的连接线路的密封材料和/或在液压块的贯通孔中密封空心轴的密封材料优选地在与制动液接触时发生膨胀(权利要求4)。这意味着，密封材料通过与制动液接触增大其体积，从而密封材料更强地压靠密封面并且更好地密封。也可行的是，最初在密封材料和密封面之间存在间隙，当密封材料与制动液接触时，通过密封材料的膨胀封闭并密封该间隙。只要存在用于密封的密封环，在本发明的设计方案中，密封环由在与制动液接触时发生膨胀的密封材料制成。并未规定制动液到达液压块的贯通孔中或者空心轴中并且在那里与密封材料接触。这种密封用于制动液不期望地与密封材料接触的情况。
例如简称为NBR(Nitrile Butadiene Rubber)的丙烯腈丁二烯橡胶适合用作用于在液压块的贯通孔中和/或空心轴中密封用于电动机的连接线路的密封材料，和/或适合用作用于在液压块的贯通孔中密封空心轴的密封材料。
所有在说明书和附图中公开的特征可以单独地或者基本上以任意组合在本发明的实施例中实现。原则上，本发明的并非具有全部、而是仅仅具有权利要求的一个或多个特征的实施方式也是可行的。
附图说明
接下来根据在附图中示出的实施方式详细解释本发明。其中：
图1示出了根据本发明的液压总成的简化的并且示意性的侧视图；以及
图2示出了根据图1中的圆圈II的细节的放大示图。
具体实施方式
在图1中示出的根据本发明的液压总成1用于此外未示出的车辆制动设备的滑动调节装置。已知的滑动调节装置是防抱死装置、驱动防滑装置和行驶动力调节装置，其中，后者也被称为电子稳定程序并且在口语中也被称为侧滑保护调节装置(Schleuderschutzregelung)。这些滑动调节装置通常被简称为ABS、ASR和FDR/ESP。这些装置是已知的，并且在此不进行解释。利用根据本发明的液压总成1也能够实现助力制动以及在助力制动时的制动压力调节。以下列举仅是示例性的而非限定性的。
液压总成1具有液压块2，在本发明所示出的和所描述的实施方式中，液压块是由例如铝合金制成的平坦的、立方体状的金属闸块。液压块2用于机械地固定和液压地连接滑动调节装置的结构元件，例如电磁阀、止回阀、液压蓄能器，减振腔、液压泵4和用于驱动液压泵4的电动机5。液压块2设有在图中不可见的、在直径上部分呈台阶状的盲孔作为用于电磁阀、液压泵4、止回阀、液压蓄能器和减振腔的容纳部以及用于连接未示出的、从主制动缸直到液压的车轮制动器的制动管路的、具有螺旋式内接头或压入式内接头(“自锁”)的接头，它们通过在液压块2内部的孔根据滑动调节装置的液压线路图相互连接。
在液压块2的平坦侧面上此外安装有电动机5，电动机的在图中不可见的马达轴伸入到液压块2中的在图中同样不可见的偏心轮腔室中，并且在那里具有用于驱动液压泵4的偏心轮。平坦侧面是液压块2的彼此对置的较大的侧面。安装有电动机5的平坦侧面在此被称为马达侧面6。
两个液压泵4彼此同轴对置地布置在泵容纳部中，所述泵容纳部设置在液压块2的两个纵向侧面中并且径向地通到偏心轮腔室中。具有泵容纳部的液压块2的纵向侧面在此被称为泵侧面7。在所示出的且所描述的实施方式中，液压泵4是也可理解成泵元件的活塞泵。
电动机5具有圆柱管形的空心轴8，所述空心轴偏心地并且轴向平行地从电动机5的端侧上伸出，电动机5利用该端侧安装在液压块2上。电动机5的连接线路9穿过空心轴8。连接线路9用于给电动机5通电。附加地，只要电动机是电子换向的电动机5，那么用于电动机5的电子换向器的连接线路9和作为例如用于电动机5的角度传感器的信号线路、传感器线路和/或数据线路的连接线路9就穿过空心轴8。在图2的放大的细节示图中，以轴向截面示出了空心轴8，从而可看到连接线路9。
具有连接线路9的空心轴8穿过贯通孔11，所述贯通孔垂直于马达侧面6穿过液压块2到达液压块2的对置的平坦侧面，该对置的平坦侧面在此被称为阀侧面12。在贯通孔11中，利用布置在空心轴8的环绕的槽中的密封环10密封空心轴8。密封环10由丙烯腈丁二烯橡胶(简称：丁腈橡胶；英文：Nitrile Butadiene Rubber；缩写：NBR)制成，即由在与制动液接触时发生膨胀的、也就是说增大其体积的密封材料制成。通常，密封环10由在与制动液接触时发生膨胀的密封材料制成，也就是说，具有电动机5的连接线路9的空心轴8利用在与制动液接触时发生膨胀的密封材料被密封在液压块2的贯通孔11中。示出了具有矩形的环形横截面的密封环10，然而，也可使用其它密封环，例如O型圈或方形圈。
利用包围连接线路9的密封材料在内部灌注空心轴8，从而也在内部密封空心轴8并且密封连接线路9。在空心轴8中的密封材料同样可以是在与制动液接触时发生膨胀的密封材料，即例如同样为丙烯腈丁二烯橡胶。
空心轴8在液压块2的贯通孔11中的密封以及空心轴8内部的密封以及在空心轴8中所穿过的连接线路9的密封的目的是：制动液不从液压块2的马达侧面6或者说从电动机5中通过贯通孔11到达液压块2的阀侧面12，具有用于电动机5的连接线路9的空心轴8穿过所述贯通孔11。
这种制动液不会意外地并且不期望地作为在渗漏时所谓的“泄漏液体”从液压泵4到达在泵容纳部之间的偏心轮腔室中，并且从偏心轮腔室中到达电动机5中。当电动机5例如机械地进行换向和/或具有用于为其转子供电的滑动触点时，电动机5的空心轴8在外部和内部的密封也会使得液压块2中的贯通孔11密封以防止颗粒通过，所述颗粒例如可能作为在电动机5中的电滑动触点的磨粒(“电刷磨粒(Bürstenabrieb)”)而产生。
当密封环10未发生膨胀时，用于使电动机5的连接线路9穿过的空心轴8的密封环10可以密封地贴靠在液压块2中的贯通孔11中。在这种情况下，当密封环通过与制动液接触而发生膨胀时，密封环10更强地向内压靠空心轴10并且更强地向外压靠贯通孔11，由此改善密封。在本发明所示出的并且所描述的实施方式中，当密封环10未发生膨胀时，在密封环10和贯通孔11之间存在间隙13。这简化了液压总成1的组装，因为在将电动机5安装在液压块2上时，空心轴8可更容易地穿过在液压块2中的贯通孔11，并且避免损坏密封环10。如果密封环10通过与制动液接触而发生膨胀，则密封环可靠地密封。
在远离电动机5的侧面上，连接线路9绝缘地从空心轴8中伸出，并且导电地与插接触点14相连接，所述插接触点布置在多重插头15中，例如布置在液压块2的阀侧面12上的插接板上。多重插头15不仅具有用于电动机5的插接触点14，而且具有另外的用于电磁阀和用于压力传感器的插接触点14。在图中不可见的电磁阀布置在液压块2的阀侧面12上。不排除布置在液压块2的其它部位上的电磁阀。此外，未示出的用于滑动调节装置的电子控制器布置在液压块2的阀侧面12上，多重插头15同样具有用于该电子控制器的插接触点14。插接触点14通常也可理解成连接触点。
根据本发明防止了制动液穿过在液压块2中用于液压总成1的电动机5的连接线路9的贯通孔11而从马达侧面6或者说从电动机5到达对置的阀侧面12，在所述阀侧面上布置有电动的构件、即电磁阀的磁性线圈，以及电子器件、即滑动调节装置的电子控制器，以及电接头、即具有插接触点14的多重插头15。
