Description

机动车中的阀装置
技术领域
本发明涉及一种用于机动车中的燃料电池系统的阀装置，具有：在壳体中延伸的流动通道；影响流动截面的阀瓣和驱动阀瓣的驱动装置，其中，阀瓣固定在轴上且该轴以可转动的方式支承在壳体中；布置在流动通道中的阀座和布置在阀瓣的径向环绕的边缘上的密封件，该密封件在阀瓣处于关闭位置时与阀座接触，从而轴以一角度穿过阀瓣。
背景技术
这类阀装置早已是已知的，因此是现有技术。由于是流动的介质、例如空气，所以调节元件必须能够在流动通道关闭时实现高度密封。此外还要确保流动通道的流动截面的以及进而流动介质的质量流量的良好调整性。尤其是在密封性方面，传统的例如作为节流阀调节器已知的阀装置是有缺陷的，这是因为由于实施类型不同，在燃料电池应用方案中的密封性要求高10倍至20倍。这结果是这种阀装置制造复杂且成本相对高。
为实现在流动通道关闭时的充分密封，基本前提条件是：在使用寿命中阀瓣紧密接合在轴上。为此公开了，将塑料制成的阀瓣与金属轴旋紧。如果在拧紧时将螺栓头压到阀瓣上，则结果是阀瓣的塑料材料由于长时间的压力屈服并由此使螺纹连接松弛，最严重时能够松脱。为了避免这点，在用于螺栓的阀瓣孔中装入金属套筒，从而螺栓的力被套筒吸收，而不会被阀瓣的塑料材料承受。在此缺陷是，套筒安装复杂，伴随有额外成本。
发明内容
因此本发明目的是，提供一种开头所述类型的阀装置，其构造更简单且同时确保阀装置在其使用寿命中的可靠的螺纹连接。
该任务根据本发明由此实现：具有凸缘，阀瓣轴具有带有凸肩部的螺纹孔，从而螺栓的凸缘与轴的凸肩部这样接触，使得在拉紧/拧紧螺栓时实现从凸缘经由凸肩部的力传递。
由于在此主要由螺栓直接向轴中实现力传递，所以明显减小了螺栓头对塑料阀瓣的压力。由于传入阀瓣中的力明显减小，所以可靠地阻止了阀瓣材料的屈服以及由此造成的螺纹连接松脱。螺栓头仅将塑料阀瓣微弱地压向轴，这对于可靠地将阀瓣固定在轴上而言就足够了。优点在于，根据本发明的连接不需要额外部件，这对装置是成本有利的。在轴上仅需要另一制造凸肩部的加工步骤，而螺栓则必须具有额外的凸缘。
为了进一步减小制造凸缘和凸肩部的成本，证明有利的是，选择到达凸肩部的深度小于轴半径。在此当凸肩部的深度为轴半径的0.2倍至0.5倍时，轴的弱化被降低至最小程度。
附图说明
借助实施例详述本发明。附图示出：
图1示出根据本发明的阀装置，和
图2示出螺纹连接的放大图示。
具体实施方式
机动车的阀装置在图1中包括壳体1，还具有布置在壳体1中供流体通流的流动通道2。在本实施例的情况下，通过阀装置调节空气流。流动通道2中布置有轴3，该轴在两侧支承在壳体1中。第一轴承4位于壳体1侧，传动机构5布置在该侧上。传动机构5在输出端与轴3连接并且在输入端与未示出的电机连接，该电动机布置在壳体1的单独的腔室6中。轴3的第二轴承7位于流动通道2的与传动机构5对置的一侧。在轴3上布置有阀瓣8，其具有孔9，轴3穿过该孔。为固定在轴3上，阀瓣8与轴3借助螺栓13旋紧。阀瓣8还具有径向环绕的边缘10，其上布置有密封件11。在该图示中，阀瓣8位于关闭位置，从而密封件11与流体通道的作为阀座12起作用的区域共同作用并且完全关闭流动通道2。
图2示出带有阀瓣8的一部分的轴3。轴3具有用于螺栓13的孔14，该孔14具有凸肩部15。螺栓13具有凸缘16，该凸缘在安装状态下贴靠在凸肩部15上。螺栓头17由此轻微地压向阀瓣8，使得阀瓣被可靠固持，但却避免塑料由于过高表面压力而屈服。凸肩部15从轴3的外表面起具有深度x，该深度约为轴半径r的0.3倍。
