Description
技术领域
本发明涉及一种用于车辆的空气弹簧的空气供应装置,其包括作为用于流入空气的处理器的空气过滤器、进气管路、排气管路、压缩机以及可选地包括空气干燥器。
此外,本发明还涉及一种用于给车辆的空气弹簧***供应压缩空气的方法。
背景技术
由EP 1 901 934 B1公知一种用于机动车辆的空气弹簧设施的空气供应装置。该空气弹簧设施具有彼此分开的进气管路和排气管路,其中,在进气管路中布置有空气过滤器并且在排气管路中布置有***。
文献DE 101 21 582 C2和EP 1 306 293 B1示出类似的具有压缩机和***的空气供应装置。
文献DE 102 23 405 B4、DE 103 01 119 A1、EP 1 608 521 B1和DE 10 2004 057 575 A1示出用于车辆的空气弹簧***或者说水平调整装置,其中,通过共同的管路导引输入空气和排出空气。然而,用于吸气和排气的共同的管路的缺点在于,空气在排出时散发湿气,所述湿气积聚在共同的管路中。之后,湿气被重新抽吸。
因此,在车辆中通常在车辆的一个位置抽吸用于产生压缩空气的空气,该位置不同于输出泄放空气(放气)的位置。由此,必须在到压缩机组件或者说到空气弹簧***的分开的管路中引导输入空气和排出空气。针对不同位置的使用的原因是有区别的。在例如从乘客车厢抽吸时,输入空气已经是相对干燥的,这减少了压缩后的干燥耗费。然而如下也被证实是有利的,即,例如直接在车辆冷却器的后方抽取输入空气。相反,泄放的排出空气可以在车辆的任意位置排出。这通常发生在压缩机或空气弹簧的组件的附近。
发明内容
本发明的任务在于提供一种可能性,即,成本低廉地实现车辆的空气弹簧的空气供应装置。
根据本发明,该任务通过根据权利要求1的特征的装置来解决。由从属权利要求得到本发明的其他设计方案。
根据本发明设置一种装置,其中,处理器布置在压缩机与第一止回阀和第二止回阀之间。由此,如下是可能的,即,用于抽吸空气和放出空气的共同的处理器与第一和第二止回阀连接,从而确保了空气能够流过独立的抽吸路径和放气路径。在此,用于流出空气的处理器构造成***而用于输入空气的处理器构造成空气过滤器和***。因为***和空气过滤器或者***现在不必作为分离的构件使用在车辆中,而是可以省掉其中一个构件,这使得制造成本和结构空间得到减少。同时,排出空气在流过处理器时能够对其进行清洁。
此外,如下是可能的,即,在排出空气流过在更新运行中工作的空气干燥器并且相应地负荷湿气之后,在用于输入空气和排出空气的共同管路的内部尽可能短地设计排出空气的路径。这样可以避免来自排出空气的湿气积聚及重新抽吸。为此,如下是有利的,即,进气管路和排气管路在共同的接合处与处理器连接。在接合处和大气之间,进气管路比排气管路长至少两倍。排气管路在结构上实施得尽可能短并且通常为15厘米长,然而不超过30厘米。
如下是有利的,即,设置在排气管路中的第二止回阀阻止水渗入排气管路。由此,如下是可能的,即,将排气管路的出口、第二止回阀和/或处理器布置在车辆的涉水深度区域中。
就作为***和空气过滤器的功能而言如下是有利的,即,处理器例如由多孔的泡沫材料组成。在过滤过程中,在空气体积流量为每分钟20至50升的情况下,这种泡沫材料吸附大小超过10微米的所有颗粒,其中,在最小空气体积流量的情况下,压力差小于或等于0.02bar。在排气时,排出空气以每分钟直至300升的体积流量沿相反的方向流过处理器的泡沫材料。
此外,如下被证实是有利的,即,处理器与第一和第二止回阀在共同的壳体中构造为模块。由此,如下是可能的,即,以理想方式实现尽可能短的共同的管路路径。因为模块具有较小的体积,所以在模块中不会积聚湿气。模块具有150至200立方厘米的体积。
就车辆中的简化安装和避免其他密封部位而言,如下是有利的,即,压缩机和空气干燥器实施为组件,该组件具有用于进气管路和排气管路的共同的接口。由此,如下是可能的,即,将组合在模块中的处理器、第一和第二止回阀简单并快速地与压缩机和原有的空气干燥器连接。
如下是有利的,即,压缩机和空气干燥器与处理器或者与模块一同构造为组件。由此,如下是可能的,即,针对在车辆中快速和简单的安装而在最小结构空间上高度一体化地预制产生压缩空气的整个功能性组件。较少数量的交接处提高了空气供应装置的质量和耐久度。
根据本发明,该任务还通过根据权利要求10的特征的方法来解决。
根据本发明设置一种方法,其中,为了给车辆的空气弹簧供应压缩空气,经由进气管路抽吸待输入空气弹簧的空气,然后输入给作用为空气过滤器的处理器,随后由压缩机压缩并且最后在空气干燥器中去湿,并且其中,首先使待从空气弹簧中输出的空气流过能在更新运行下工作的空气干燥器,随后经由旁路绕过压缩机并通过作用为***的处理器经由排气管路中的第二止回阀泄放到周边环境中。
伴随着方法步骤“压缩机产生负压,通过负压打开布置在输入管路中的第一止回阀并且通过弹簧力和负压关闭布置在排气管路中的第二止回阀”而实现了将大气中的输入空气输送至压缩机以及在此发生的处理器中的过滤。
为了泄放压缩空气,来自空气弹簧的排出空气为了绕过压缩机而经由旁路导引,此后,排出空气流过处理器,布置在进气管路中的第一止回阀通过排出空气的压力和弹簧力而关闭并且布置在排气管路中的第二止回阀通过排出空气的压力而打开。
附图说明
本发明允许不同的实施方式。为了进一步阐释其基本原理,在附图中示出其中一种实施方式并在下面进行说明。其中:
图1示出了空气供应装置的线路图;
图2示出了模块的截面图,该模块具有图1中所示的空气供应装置的处理器与第一和第二止回阀;
图3示出了图1中所示的空气供应装置的组件的分解图。具体实施方式
图1示出用于这里未示出的车辆的空气弹簧***9的空气供应装置1。空气供应装置1包括处理器2,该处理器过滤通过进气管路3流入的空气。此外,空气供应装置1包括排气管路4、压缩机5以及可选地包括空气干燥器6。进气管路3和排气管路4通过第一止回阀7和第二止回阀8彼此分离。处理器2布置在压缩机5与第一止回阀7和第二止回阀8之间。进气管路3和排气管路4在共同的接合处10与处理器2连接。
为了从大气输送输入空气至空气弹簧***9,压缩机5抽吸输入空气并且在空气干燥器6中将其干燥。在输入空气到达压缩机5之前,在处理器2中对其进行过滤。通过由压缩机5产生的负压来打开布置在进气管路3中的第一止回阀7而通过弹簧力和负压来关闭布置在排气管路4中的第二止回阀8。在泄放处于空气弹簧9中的压缩空气时,压缩空气流过空气干燥器6并且将其更新。为了绕过压缩机5,排出空气通过旁路13导引。可控阀门17处于旁路13中,该阀门仅在放气的情况下打开。之后,排出空气流过处理器2。布置在进气管路3中的第一止回阀7通过排出空气的压力和弹簧力关闭而布置在排气管路4中的第二止回阀8通过排出空气的压力打开。
在所示实施方式的变型方案中,处理器5与第一和第二止回阀7、8在共同的壳体14中构造为模块11。压缩机5和空气干燥器6与模块11一同构造为组件12。
图2在剖面图中示出图1所描述的模块11。第一和第二止回阀7、8以及处理器2处于模块11的共同壳体14中。壳体14具有用于进气管路的接口16和用于到压缩机或者说到组件的管路的另一接口15。可选地,放气管路可以联接在放气端口18处。
图3示出图1中所描述的组件12,其由空气干燥器6、模块11和这里未示出的压缩机5组成,所述组件12具有带封闭盖22的壳体20,该壳体容纳空气干燥器6的干燥剂19、处理器2、阀门17、节流阀21与第一和第二止回阀7、8。
