Description

压力变化阻尼器和带有该阻尼器的车辆液压制动设备
技术领域
本发明涉及一种带有权利要求1的前序部分所述特征的用于受制动力调节的车辆液压制动设备的压力变化阻尼器以及根据权利要求7所述的带有这种压力变化阻尼器的受制动力调节的车辆液压制动设备。
背景技术
“受制动力调节”意指，在车轮制动器中的车轮制动压力和因此车辆液压制动设备的车轮制动器的制动力优选地可针对单个车轮地进行调节，例如以用于防抱死制动调节、驱动防滑调节和/或行驶动力学调节(其通俗地讲还被称为防滑调节)、自动制动或自动地间距调节，对于它们例如使用缩写ABS、ASR、FDR、ESP、ACC。列举是示例性的并且不是决定性的。这种制动力调节原则上是已知的，并且在此不应对其进行详细探讨。
受制动力调节的车辆液压制动设备通常具有液压泵，在大多数情况下在每个制动回路中具有一个液压泵，液压泵还被称为回流泵并且通常为活塞泵。活塞泵由于其振荡的输送方式引起在车辆液压制动设备的制动液体中的压力波动。用于车轮制动压力调节的电磁阀在切换时引起在制动液体中的压力冲击。为了衰减在车辆液压制动设备的制动液体中的这种压力变化，已知压力变化阻尼器，其应如作用到主制动缸上的反作用一样降低噪声生成。
国际专利申请WO2011/028376A2公开了一种受制动力调节的车辆液压制动设备，该车辆液压制动设备带有串列式或双回路主制动缸，在其处联接有两个制动回路。为了进行制动力调节，已知的车辆制动设备具有电磁阀、止回阀，并且在每个制动回路中具有高压存储器、活塞泵和压力变化阻尼器，压力变化阻尼器联接在活塞泵的泵出口处，即联接在活塞泵的压力侧处。在一种实施方式中，已知的压力变化阻尼器具有穹顶状的硬的阻尼器壳体，在其中布置有软管状的、由弹性体制成的阻尼器元件。穹顶状意指在一端部处闭合的并且在相对而置的端部处敞开的管状。阻尼器元件同样具有闭合的端部，其布置在阻尼器壳体的闭合的端部中。阻尼器元件的敞开的端部布置在阻尼器壳体的敞开的端部处或中。压力变化阻尼器布置在车辆液压制动设备的制动力调节***的液压块中的容纳孔中，其中，阻尼器壳体和阻尼器元件的闭合的端部面向容纳孔的底部。在液压块中的容纳孔的入口中压入塞状的保持器(Halter)，其耐压且流体不可透过地闭锁容纳孔并且将在阻尼器元件的敞开的端部处的向外伸的边缘固定在在阻尼器壳体的敞开的端部处的法兰和保持器的环形梯级之间。塞状的保持器以所谓的自紧技术(Self-Clinch-Technik)固定在液压块中的容纳孔的入口中。自紧意指环形地填缝，在其中在压入保持器时液压块的材料塑性地变形到保持器的环形槽口中并且流体不可穿透且耐压地在容纳孔和保持器之间进行密封。为了变形，保持器具有环形凸肩，其尤其带有比保持器更大的直径，该环形凸肩在压入方向上位于环形的槽口之后。
发明内容
具有权利要求1所述特征的根据本发明的压力变化阻尼器设置成用于受制动力调节的车辆液压制动设备。压力变化阻尼器具有管状的阻尼器壳体，在其中布置有可弹性变形的软管状的阻尼器元件。“管状”不一定意指是圆柱状，而是例如还可是多边形的和/或逐渐变细和/或逐渐扩张。阻尼器壳体尤其为穹顶状，对此意指单侧闭合的管状形状，其中，闭合的端部例如可是平坦的或拱顶状的。软管状的阻尼器元件同样优选地在一端部处闭合并且尤其由弹性体(例如EPDM)构成。
根据本发明，压力变化阻尼器具有阀组件，阀组件带有管状的阀壳体和同样管状的阀座部件，阀座部件具有阀座且压入到阀壳体中。阀壳体布置在阻尼器壳体的敞开的端部处，例如阻尼器壳体和阀壳体别在一起或压在一起。在阀壳体中布置有阀，例如进入阀或排出阀，其控制至压力变化阻尼器的流入或从压力变化阻尼器的流出。阀例如为止回阀或流量调节阀。
本发明具有的优点是简单且成本合适的可制造性。
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的设计方案和改进方案。
由于相比于成本密集地切削加工制造带有阀座的阀壳体成本合适且快速的可制造性，根据权利要求4通过变形、尤其深冲制造阀壳体和/或阀座部件是特别优选的。
此外，本发明涉及一种根据权利要求7所述类型的带有压力变化阻尼器的受制动力调节的车辆液压制动设备，其中，压力变化阻尼器尤其联接在泵出口处，即联接在车辆液压制动设备的制动力调节***的液压泵的压力侧处。如开头说明的那样，这种液压泵通常为活塞泵，其由于振荡的输送方式产生根据本发明的压力变化阻尼器衰减的压力波动。
附图说明
本发明的其他特征由本发明的实施方式的随后说明结合权利要求和附图得到。各特征可单独地或对多个特征以任意组合的方式在本发明的实施方式中实现。唯一的附图显示了根据本发明的压力变化阻尼器的轴向截面。
具体实施方式
在附图中示出的根据本发明的压力变化阻尼器1具有管状的阻尼器壳体2，其带有敞开的端部和闭合的端部，这还可理解为穹顶状。在阻尼器壳体2中布置有软管状的阻尼器元件3，其同样具有敞开的端部和闭合的端部。阻尼器元件3包含弹性材料，在该实施方式中包含弹性体，其可发泡。阻尼器元件可弹性变形并且还可压缩，即，可弹性地改变体积或壁厚。阻尼器元件3具有近似筒状的、微微渐细的空腔4，空腔从敞开的端部起在阻尼器元件的长度的约2/3内延伸。在纵向方向上大约在空腔4的端部的高度上，阻尼器元件3在其闭合的端部处在外部截锥状地以环形的波状部5逐渐变细。阻尼器元件3的外径小于阻尼器壳体2的内径，从而阻尼器元件3在阻尼器壳体2中被间隙6包围。阻尼器元件3在敞开的端部处具有环形的、斜向外伸出的***部7，该***部带有近似圆形的环截面。阻尼器元件3的壁厚在阻尼器元件3的敞开的端部处在从***部7到软管状部分的过渡部8处最薄。
阻尼器元件1具有阀组件9，其沿轴向布置在阻尼器壳体2的敞开的端部处。阀组件9具有管状的阀壳体10，该阀壳体带有比阻尼器壳体2更小的直径。在阻尼器壳体侧的端部处，阀壳体10具有直径扩展部作为用于阻尼器壳体2的敞开的端部的容纳部11。容纳部11具有管状颈圈的形状，在其中***或压入阻尼器壳体2的敞开的端部。阀壳体10的从管状颈圈11到管状的且直径更小的部分中的过渡部具有环形凹槽12的形状。尤其管状的阀壳体10的形成用于阻尼器壳体2的敞开的端部的容纳部11的颈圈和环形凹槽12通过变形制成，例如通过深冲制成，其中，在该实施方式中，阀壳体10整体通过变形、尤其深冲制成。阀壳体10的容纳部11(其具有管状颈圈的形状)和紧接的环形凹槽12与阻尼器壳体2的敞开的端部一起形成环形槽口，在其中放入在阻尼器元件3的敞开的端部处的***部7。槽口朝向内指向的槽口开口(8)的方向上缩小其横截面，其形成最窄的部位，从而***部7保持在在阻尼器壳体2的敞开的端部和容纳部11和环形凹槽12之间的环形槽口中。因此，阻尼器元件3的敞开的端部被保持在阻尼器壳体2的敞开的端部处或该敞开的端部中，并且封闭和密封在阻尼器壳体2中包围阻尼器元件3的间隙6。
在阀壳体10中压入管状的阀座部件13，阀座部件在其面向阻尼器元件3的端部处空心截锥状地逐渐变细并且以短的管状颈圈终止。截锥状的渐细部的内侧形成用于流量调节阀15的阀座14，流量调节阀布置在管状的阀座部件13中。形成阀座14的渐细部通过变形(例如深冲)制成，其中，在该实施方式中，阀座部件13总体通过变形、尤其深冲制成。相比于切削加工制成的阀座，通过变形制成的阀座14在制造成本为几分之一的情况下具有明显更高的质量和紧密性。
阀壳体10在外部在从管状部分至环形凹槽12的过渡部处具有加强筋16。加强筋16桥接在从阀壳体10的凹槽12至管状部分的过渡部处的环形沟槽并且加固阀壳体10和凹槽12。加强筋16布置在轴向平面中。
流量调节阀15具有空的阻塞体17，其由阀弹簧18以预紧力朝阀座14加载。在该实施方式中，阀弹簧18为螺旋压力弹簧，其支撑在管状的弹簧保持器19处，该弹簧保持器与阀座14相对地压到阀座部件13中。流量调节阀15的阻塞体17具有轴向的通孔，该通孔带有截锥状的渐细部，其形成止回阀21的阀座20。在流量调节阀15的阻塞体17的通孔中容纳有球体作为止回阀21的阻塞体22。在示出的实施方式中，止回阀21无弹簧，但还可实现用弹簧加载的止回阀(未示出)。
阻尼器壳体2在敞开的端部附近构造为用于自紧连接的插座(Stemmmuffe)23。为此，阻尼器壳体2在外部在其敞开的端部附近具有带有弄圆的槽口截面的环形槽口24，环形槽口的在压入方向上后部的槽口侧部25布置在阻尼器壳体2的径向平面中并且向外突出。在压入到液压块27的容纳部26中时，槽口侧部25使液压块27的包围容纳部26的材料塑性变形到插座23的槽口24中，从而阻尼器壳体22在机械上稳定地保持在液压块27中并且耐压地密封在容纳部26中。
在液压块27中的容纳部26为在直径上分级的盲孔，其中，在压入阻尼器壳体2时，布置在其敞开的端部处的阀壳体10被压入到容纳部26的直径更小的轴向的延伸部28中并且由此在周边处被密封。
液压块27(对于其，在附图中仅仅示出了包围用于压力变化阻尼器1的容纳部26的一部分)为未进一步示出的车辆液压制动设备的制动力调节***的部件。液压块27具有用于制动力调节***的液压的结构元件(例如液压储存器、电磁阀和液压泵)的其他容纳部以及用于通至主制动缸和车辆制动器的制动管路的接头(未示出)。液压的结构元件和用于制动管路的接头通过液压块27的钻孔液压地彼此连接。受制动力调节的车辆制动设备的这种液压块对于本领域技术人员是已知的并且在此不做进一步阐述。利用制动力调节可以已知的方式实现防抱死制动调节、驱动防滑调节、防滑调节或行驶动力学调节、自动制动和间距调节(adaptivecruisecontrol，自适应巡航控制)，对于它们例如使用简称ABS、ASR、FDR、ESP、ACC。列举是示例性的且并不是决定性的。
在用于压力变化阻尼器1的容纳部26的直径更小的延伸部28和容纳部26之间的环形梯级处通入作为斜孔实施在液压块27中的输入管路29，其通过阀壳体10中的径向孔洞30与阻尼器元件3的空腔4相连。孔洞30在周向上分布地在阀壳体10中设置在阀座14和环形凹槽12之间。压力变化阻尼器1通过输入管路29与制动力调节***的未示出的液压泵、尤其活塞泵相连。压力变化阻尼器1衰减在制动液体中的、由活塞泵基于振荡的输送方式产生的压力脉动。
在阻尼器元件3中的空腔4通过止回阀19和流量调节阀15与实施成与轴线平行的孔的出口31相连，该孔偏心地通到用于压力变化阻尼器1的容纳部26的延伸部28的底部中并且过渡到横向孔中。在本发明的示出的实施方式中，止回阀19和流量调节阀15为压力变化阻尼器1的排出阀。
