Description

用于减振器的阻尼阀
技术领域
本发明涉及一种按照权利要求1的前序部分所述的阻尼阀。
背景技术
文献DE 10 2014 223 085 A1说明了一种具有环形沟槽的阻尼阀,所述阻尼阀径向向内并且径向向外地由阀座面限定。在阀座面上存在至少一个阀盘,所述阀盘根据压力在均匀深度的环形沟槽内部实施提升运动。为了避免振动噪音对于阀盘来说争取达到尽可能唯一一个提升点。在文献DE 10 2014 223 085 A1中充分利用阀座面的粘合作用并且因此在阀座面的整个周面上使用月牙轮廓。在阀座面的最小径向宽度的区域中首先提升阀盘。
备选地,能以径向不同的宽度确定环形沟槽的尺寸或者相对于环形沟槽偏心地设置阀盘,比如像在文献DE 21 09 398 A1中公开的那样。
发明内容
本发明的任务在于,以尽可能简单的方式实现一种阻尼阀,该阻尼阀中至少一个阀盘尽可能在阀座面的唯一一点处开始提升。
该任务通过如下方式解决,即环形沟槽的底面在一圆周区域上具有相对于阀座面的最大间距,并且在另一圆周区域中具有相对于阀座面的最小轴向间距。
在经由环形沟槽流入阀盘时设置不均匀的压力水平。所述压力水平在底面相对于阀座面具有较大间距的区域中大于在底面相对于阀座面具有较小间距、亦即较平坦的环形沟槽的区域中。为此,起决定性作用的是不同的环形沟槽横截面,所述环形沟槽横截面为节流阀,所述节流阀于是在环形沟槽中导致压力差。通过有针对性的压力利用能够鉴于噪音特性有利地影响阀盘的打开特性。另一个优点在于,还能够使用均匀圆形的阀盘。
阻尼阀体通常以烧结技术制造。为了有利地影响制造过程,环形沟槽在具有最大间距的圆周区域与邻接的、具有较小间距的圆周区域之间具有倾斜的过渡区域。利用该过渡区域将突兀的横截面变化最小化。
在另一种有利的设计方案中,由于在所述环形沟槽中的间距差而形成的材料体积的至少一部分相对于所述阻尼阀体的功能面隔开地设置。在烧结技术制造的情况下争取达到在构件中的对称性。环形沟槽的深度不同会干扰该对称性。因此,为了平衡进行材料堆积,该材料堆积发生在功能面、比如像阀座面或者张紧面的外部。
按照一项有利的从属权利要求,在环形沟槽中设置材料体积。所述环形沟槽首先用于在阀盘上提供大的压力加载的面。当利用材料体积填满环形沟槽的一部分时,那么其仅仅显示环形沟槽的几乎不可测量的功能损坏。
于是规定,在材料体积的上侧面与阀座面之间存在轴向凹部。通过该措施会阻止材料体积对于阀座面的支撑功能。
附加地,所述材料体积能够设置在环形沟槽的具有最大间距圆周区域中。该措施的意义在于,将为了加深环形沟槽而挤压的材料体积放置在尽可能短的路径上。由此能够有利地影响烧结过程。
在另一种设计方案中,材料体积是锥体。利用所述锥体形状会避免突兀的横截面变化,所述横截面变化例如能够用于在环形沟槽中流动中的涡流。
试验已经证明特别有利的是,环形沟槽在最大间距的圆周区域中具有至少两个相邻的流入开口并且所述材料体积设置在所述两个流入开口之间。特别是结合材料体积的锥形形状有利地影响在环形沟槽中的流动横截面。
可选地,阻尼阀体在背离环形沟槽的侧面上在整个周面上具有与阻尼阀体的纵轴线成直角的平面。其优点在于,还能够使用常规的阀盘。
结合不同的环形沟槽深度被证实为非常有利的是,所述阀座面中的至少一个阀座面具有月牙形状,其中,所述阀座面的具有最大径向宽度的圆周区域设置在所述底面相对于所述阀座面的间距最小的圆周区域中。通过组合两个单个效果、亦即在环形沟槽中的不同的压力分布以及阀座面粘合到阀盘上的不同粘合效果的作用,还能够更强地影响阀盘的提升性能,其中,能够无需特别定向地沿周面方向安装所述阀盘本身。
附图说明
根据以下对附图的说明更详细地阐述本发明。图中:
图1示出了减振器的截取区段;
图2示出了阻尼阀体的透视图;
图3示出了阻尼阀体的俯视图;
图4示出了阻尼阀体的剖视图;
图5A、5B示出了阀座面的阀视图。
具体实施方式
图1示例性地示出了结构型式为双管阻尼器的减振器1的截取区段,该双管阻尼器在利用阻尼介质填充的工作空间3与补偿空间5之间具有结构型式为底阀的阻尼阀7。原则上,阻尼阀7也能够应用在活塞杆上或者用作相对于可调整的阻尼阀的先导阀(Vorventil)。这种应用可能性既不局限于示图也不局限于前面所提到的情况。
阻尼阀7包括多个针对不同的穿流方向的、穿透阻尼阀体9的、单独的穿通通道11、13。针对各一个穿流方向的穿通通道11、13构造在一个共同的分度圆上。穿通通道11将补偿空间5与工作空间3连接,其中,阻尼介质的流入开口15(见图2)由至少一个阀盘17覆盖。
阻尼介质沿相反方向经过穿通通道13流到补偿空间5中,其中,在这里流入开口15也由至少一个阀盘21(见图1)覆盖。由针对朝向工作空间的流动方向的阀盘17、阻尼阀体9和针对朝向补偿空间的流动方向的阀盘21组成的整个组合体由紧固器件23、多个铆钉组装在一起并且形成一可操作的结构单元。
在图2中透视地并且在图3中以常规的俯视图示出了阻尼阀7的阻尼阀体9的实施例。穿通通道11优选具有弧形的排出开口,该用于环形沟槽的排出开口是在底面27中的流入开口15。环形沟槽25通过环状的、关于阻尼阀7的中轴线位于径向内部的连接片29和环状的、关于阻尼阀7的中轴线位于径向外部的连接片31限定(见图4)。这两个连接片29、31分别构成用于在图1中所示出的阀盘17的阀座面33、35。
外部的连接片31具有两个功能区域。在第一圆周区域37中,连接片31的阀座面35包括用于阀盘17的径向宽的平坦的面支承部,该面支承部在连接片31的至少60%上延伸。在这里外部的连接片31具有梯形的横截面。在这里示出的实施变型方案中第一区域在连接片的大约75%上延伸。外部的连接片31的第二圆周区域39具有在横截面中倒圆的阀座面,由此该第二圆周区域不提供用于阀盘的面支承部,而是线支承部。用于线支承部的边界由用于阻尼阀体的制造方法和不可避免的磨损确定。由此针对第一圆周区域产生月牙形状的接触区。
当然,所述第二圆周区域39也能够以其它横截面形状、比如在横截面中锐角地或者类似地构造,然而已经证明,具有半径的支承部在阻尼阀的使用寿命期间是特别稳固的并且在制造方面是特别简单的。此外,在此可以通过半径R的大小限定阀盘的支承部并且确定减小粘合作用。
此外,由图2和图4的总览可看到,环形沟槽25的底面27在圆周区域41上具有相对于阀座面35的最大间距(见图4剖视图的左半部分)并且在另一圆周区域上具有相对于阀座面35的最小轴向间距(见右半部分)。
阀座面35的具有月牙形状的区域这样沿圆周方向相对于环形沟槽25定向,从而阀座面的具有最大径向宽度的圆周区域设置在底面27相对于所述阀座面35的间距最小的圆周区域中。
在具有最大间距的圆周区域43与邻接的、具有较小的间距的圆周区域41之间环形沟槽25具有过渡区域45。在所述实施例中阻尼阀体9具有环形沟槽的仅两个深度区域,从而具有较小的间距的圆周区域是具有最小间距的圆周区域。
在图2中示出的阻尼阀体9优选以成型方法制造,例如烧结方法、注塑方法、压铸方法。在所有提到的方法中争取达到在工件上均匀的材料分布。特别是针对烧结方法规定,由于环形沟槽25中的间距差而产生的材料体积47的至少一部分相对于阻尼阀体9的功能面33、35隔开地设置。由此即使在所述结构形式中也已经能够应用针对常规的阻尼阀体的上述阀盘。
如图2和图3进一步示出的那样,在环形沟槽25中设置通过针对不同的环形沟槽深度的材料堆积而产生的材料体积47,从而针对材料体积47仅产生小的堆积路径,特别是当材料体积47设置在环形沟槽25的具有最大间距的圆周区域43中时。
在此注意,在材料体积47的上侧面49与阀座面33、35之间存在轴向凹部。能由阻尼介质加压的面的大小不应该由于材料体积47而减少。该细节在图5A中放大地示出。
环形沟槽25在最大间距的圆周区域43中具有两个相邻的流入开口15,其中,材料体积47设置在所述两个流入开口15之间。在此,所述材料体积构造为锥体,从而每个流入开口15存在各一个漏斗半部(见图2)。
如由图4可看到的那样,阻尼阀体9在背离环形沟槽25的侧面上在整个周面上具有与阻尼阀体的纵轴线成直角的平面。特别是在阻尼阀体的下侧面上具有针对阀盘21的排出开口的环形沟槽51不受在上侧面上在环形沟槽25中积聚的材料体积47的影响。
在流入阻尼阀7进而将阻尼介质输送到环形沟槽25中时,持久地存在已填充的环形沟槽,因为工作空间3基本上以阻尼介质填充。因此,存在动态的流入状态,基于该流入状态对环形沟槽25中的不同的横截面产生作用。在环形沟槽的具有较大间距的圆周区域43中在底面27与阀座面35之间横截面更大并且因此通流阻力较小。因此,在那里能够使阻尼介质更轻易地经过环形沟槽25。通过阀盘19在阀座面35上的线接触支持提升运动,或者说通过基于在底面27与阀座面35之间具有最小间距的圆周区域41中的在阀盘17与阀座面35之间的、径向相对宽的阀座面的期望的粘合效果支持提升运动。
