Abstract
本发明涉及起爆传感器，其属于内燃机并包括可被电子评价的震动传感器。本发明目的是提供一种具有简单结构并可被合理安装的起爆传感器。为达到此目的，该振动传感器具体化为压阻无定型碳层。
Description
技术领域
本发明涉及一种用于带电子测评振动传感器的内燃机的起爆传感器，这种公知起爆传感器的振动传感器是以例如压电陶瓷元件的形式实现的。
背景技术
该种类型的起爆传感器被例如EP0472219B1、EP0844470B1和DE19539919C2所公开。
发明内容
本发明是基于实现该种类型的电子测评振动传感器的目的，由此该振动传感器具有更加简单的设计，与目前相比，可更加合理地应用在起爆传感器内。另外，测量信号的传输更趋简化.
为达到本发明的目的，相应的振动传感器首先以压阻无定形碳层的形式实现，该压阻无定型碳层被刚硬地涂敷到基体的表面部分，并且可能最好由金刚石结构碳(Diamond Like Carbon)层组成。该碳层及其应用，例如，是通过物理气相沉积(PVD)或化学气相沉积(CVD)的方法，与传感器一起在DE19954164A1中被描述，该传感器是由该碳层制成，并用来确定机械元件的参数值.提供有测量碳层并用来控制非阳性连接的垫圈也公开在DE19831372A1中。
根据本发明的起爆传感器的实施例构成了从属权利要求对象。因此，传统的提供在起爆传感器中并作为拉紧装置的弹簧垫圈特别是可作为基体用，在其上加有测量碳层。
对比现有技术，本发明旨在删除通常由在该种类型起爆传感器中的振动传感器组成的附加元件，也就是说，直接将薄的测量层加到不仅仅是执行振动传感器功能的元件表面上。将测量层加到起爆传感器内提供的弹簧垫圈形式的拉紧元件上是特别有益的。弹簧垫圈可以实现，特别是以这样一种方式，以致依靠弹簧垫圈通常被支撑在起爆传感器内的振动传感器的地震块是弹簧垫圈的主要部分。
在根据本发明应用的压阻无定型碳层中，内燃机的振动在该碳层中产生电压变化，例如，当所述振动对弹簧垫圈产生影响时，其中这些电压变化可被传统地测定出。当利用带有压阻无定型碳层的弹簧垫圈时，弹簧垫圈的变形可以用来在碳层中产生电子可测量的电压变化。
如果所述碳层设置在地震块和用于刚性连接内燃机的地震块的邻接之间，在未利用弹簧垫圈的情况下，压阻无定型碳层中的压力负载变化可被测评出。
根据本发明的测量层的高测量敏感度特别适合遥感勘测的信号测评。关于为此目的需考虑的遥感勘测的信号评价方法的原理，我们参考现有技术，例如，根据DE4034019C1、EP0533709B1和DE3714195A1。
附图说明
本发明的优点和实施例在附图中阐明。
附图分别以纵断面形式示出。
图1是带有弹簧垫圈的起爆传感器的第一实施例，弹簧垫圈设置于地震块和与内燃机刚性连接的邻接之间。
图2是根据图1的起爆传感器，其带有的垫圈或弹簧垫圈在根据图1的平面状态。
图3是带有在地震块和邻接之间的金刚石结构碳层的起爆传感器，该邻接可被刚性安装在内燃机上。
图4是带有通过螺丝拉紧的地震快的起爆传感器，其中，所述金刚石结构碳层设置在螺丝头的下方以及安装本体上。
图5是根据图1的起爆传感器，其带有的弹簧垫圈通过一个特殊螺丝拉紧到一限定值。
图6是带有弹簧垫圈和特殊螺丝的起爆传感器，该螺丝用来拉紧弹簧垫圈并可直接螺接到内燃机上。
图7是带有夹置于两弹簧垫圈之间的地震块的起爆传感器。
具体实施方式
根据图1的起爆传感器包括安装本体1和螺丝2，安装本体1被刚性螺接至内燃机的外壳，该螺丝2被紧固在安装本体1中。通过设于中间的弹簧垫圈4，该螺丝头夹持地震块3抵于安装本体1。
指向螺丝2的头部的弹簧垫圈4的表面部分提供有以金刚石结构碳层形式的压阻无定型碳层。电线6从该碳层通向电子评价单元(图中未示出)。碳层厚度最好在1到10μm的范围内。
如果内燃机出现爆震，环行结构地震块3会通过弹簧垫圈起作用并从而受到刺激。这样致使地震块施加相应的负载到弹簧垫圈4，从而在加到弹簧垫圈4上的金刚石结构碳层5中出现相应的电压变化。该电压变化通过电线6传输给电子测评从而在其中得到评价。为了实现遥感勘测传输，来自碳层5中的测量信号可通过无线电发射接收机进行传输，该无线电发射接收机设置在与金刚石结构碳层5一同考虑的元件上。通过这种通常的传输原理，常规的传输电缆和它们的连接装置可以除去。
在根据图2的实施例中，弹簧垫圈可替换为垫圈7，如果需要，该垫圈7也可由平夹式弹簧垫圈4组成。
原则上，也可被想得到的事，将金刚石结构碳层5分别加到弹簧垫圈4或垫圈7的两侧上。
当使用垫圈7时，通过垫圈7内主要的切向拉力和/或压缩压力，在金刚石结构碳层8中产生电子评价电压。
根据图3的实施例既不包含弹簧垫圈也不包含垫圈7，但包含金刚石结构碳层8，其直接设置在地震块3和安装本体1之间设置。振动在金刚石结构碳层8内以压缩压力的形式传感。
在根据图4的实施例中，金刚石结构碳层9和10设置在地震块3的两个相对的夹紧区域，其中，所述的碳层一方面被刚性连接到安装本体1上，另一方面连接到螺丝2的头部。
图5示出一起爆传感器，其中使用了特殊螺丝11来拉紧弹簧垫圈4。与螺丝11一体的限位环12可较容易地借助于该特殊螺丝来调整弹簧垫圈4的限定张力。
当利用这样的特殊螺丝11时，如图6所示的相应旋上安装本体可以省去。
在根据图7所示的实施例中，地震块3’被夹持在两个弹簧垫圈4和4’之间。如果仍然需要，在本实施例中可以考虑取消地震块。
所有示出的起爆传感器都提供有一个保护罩13。
