Abstract
液力弹簧的流体容积(4a,4b)一方面通过一个弹簧元件(6)加以封闭,该弹簧元件硫化在一个外环(8)中;另一方面,流体容积(4a,4b)通过一个补偿膜片(10)加以限定。流体容积(4a,4b)通过一个具有至少一个连接通道(28)的分隔壁(26)而分成为两个灌满了一种液压流体的并可交替地改变容积的腔室(4a,4b)。为了提供一种只需要很小结构高度的减振元件,将分隔壁(26)设计成平的,为此,分隔壁平面横交于弹簧轴线加以定向。在平的分隔壁(26)内实现定向的,在平的分隔壁(26)内部延伸着至少一个平的连接通道(28)。最好将至少一个连接通道(28)设计呈螺旋形的。也可设计多个螺旋形的通道。在此可将多个设计成螺旋形的连接通道(28)彼此错开地布置在分隔壁(26)中。
Description
本发明涉及一种配有减振器的液力弹簧,特别是作为初级弹簧用在轨行车上,如在专利文件DE 44 46 800 C1中所公开的名称也叫“液力减振弹性支承体”的液力弹簧。
该专利文件中参照其中所含图1a所描述的支承体具有“一个弹簧元件(1)”,该弹簧元件一方面同一个连接部件(11)、另一方面同一个筒形外壳(3)牢固地相连,特别是彼此共同硫化在一起。对置的连接部件(12)螺纹连接在外壳(3)上,具有杯形空气补偿孔(13.1)的支承盖(13)是与该连接部件连成一体的。支承体的液力减振系统包含:工作腔室(6)和向外通过高挠性的弹性补偿膜片(2)所封闭的补偿腔室(7)以及一个在分隔壁(5)中成形的连接通道(4),通过该连接通道,被封闭的液压流体可以受节制地在上述两个腔室之间来回流动。
根据这一现有技术,被安置在该弹性支承体内的分隔壁(5)具有一个筒状边缘,在此边缘上开出了一个螺旋状的槽。与外壳(3)相结合,在筒形边缘上所开出的槽形成一个通道(4),该通道将两个流体腔室(6和7)彼此连通起来。
在筒形边缘上开出的槽,其加工成本是相当昂贵的。由于其轴向膨胀之故,筒形边缘需要一定的结构高度,该高度是不能作为弹簧行程利用的。利用已知的连接通道(减振通道4)不可能将减振作用调节到待被赋予弹性的物质上。
本发明的任务在于将已知的液力弹簧加以进一步发展。特别是应提供一种价廉的、要求一很小结构高度的减振元件。
按权利要求1,根据本发明的一种减振通道处在一个唯一的横交于弹簧轴线布置的平面中。从而得出一个很小的结构高度。这就是说:要么是可将通常为减振通道所需的结构高度用于一个扩大的弹簧行程,要么是在相同的弹簧行程条件下可将弹簧总体设计得结构较小。
通过刚才所述及的引导液压流体的减振通道(连接通道)的螺旋状结构,就能达到足够的流通长度,从而根本不须对减振效应折中。
不仅就通道长度而言是如此,而且还有足够的间隙空间。也可以设计出多个连接通道,将它们彼此错开地布置在一个平面中,其中,各个流动路线是彼此并联的。由于将节流阀分配到多个单独的通道上,所以这些通道可以设计成不同长度和具有不同横断面。这样,可以实现更加宽带式的减振,而不使减振最大值下降。
此外,也可考虑在多个平面内布置多个连接通道。这样就可实现任意大的减振效应。
这些连接通道最好借助于两个彼此上下相叠的且各自带有相对取向的槽的圆盘(节流阀上部和节流阀下部)构成,这些圆盘共同形成一个分隔壁。
如果这两个形成液力通道的圆盘可以彼此逆向扭转的话,便可改变有效的横断面。这样,就可调节减振特性。
最后可通过对通道表面的粗结构和细结构的选择而进一步调节减振特性。
下面将参照一个实施例对根据本发明的液力弹簧做详细说明。附图所示为:
图1以纵剖面示出了根据本发明的液力弹簧,
图2示出了安置在液力弹簧内部的分隔壁,亦即:
图2a以纵剖面示出了根据本发明的分隔壁;
图2b示出了从下看去的分隔壁的上部(节流阀上部);
图2c示出了从上看去的分隔壁的下部(节流阀下部);
图2d以纵剖面图示出了上部;和
图2e同样以纵剖面图示出了该下部。
图1所示液力弹簧2的流体容积4a、4b向“下”由一个弹簧元件6加以封闭,该弹簧元件被硫化在一个外环8中。流体容积4a,4b向“上”通过一个膜片10加以限定。
膜片10利用一个盖12压力密封地固定在外环8上。为此目的,外环8和盖12都分别具有一个平的密封面14及16。在这两个平的密封面14、16之间延伸着膜片10的外边缘18。将盖12和外环8彼此连接起来的螺钉20用于将盖12压力密封地固定在外环8上。
为了达到弹簧效应的减振,流体容积4a、4b是通过一个配有至少一个连接通道28的分隔壁26而分成为两个部分容积(工作腔室4a、补偿腔室4b)的。
分隔壁(节流阀)26由节流阀上部26a和节流阀下部26b组成。这两个部分26a、26b配有彼此相应的螺旋状的槽30a、30b(图2),这两个槽共同形成连接通道(补偿通道)28,其中,补偿通道28的一端汇入到一个腔室4a或4b中,补偿通道28的另一端则汇入到另一个腔室4b或4a中。
在实现弹性的过程中,腔室4a、4b可以交替地改变容积,其中,液压流体流过连接通道28。基于液压流体的粘度之故,在其流过连接通道28时可以产生或多或少有力的减振作用。
按所示的实施例,分隔盘26的上部26a和下部26b是可以彼此逆向地扭转的,因此可改变有效的通道横断面。减振效应除了与液压流体的粘度有关之外,还与通道28的长度和有效横断面及表面结构有关。
