Description
技术领域
本发明涉及一种用于内燃机的带电子测评振动传感器的起爆传感器。
背景技术
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。该种类型的起爆传感器被例如EP0472219B1、EP0844470B1和DE19539919C2所公开。
US 4,448,059A公开了一种用于内燃机的带压阻层形式的电子测评振动传感器的起爆传感器，该压阻层被刚硬地加到基体的表面部分。
DE 199 54 164公开了用于测定状态变量的传感器，特别是通过利用厚度在10nm到500μm之间的无定形碳层来确定由机械元件施加的力。这些无定形碳层可以特别由金刚石结构碳(Diamond-Like Carbon)层组成并具有压阻特性。这些碳层可用不同的几何形状施加到表面上。例如，这些碳层可通过物理气相沉积(PVD)或化学气相沉积(CVD)的方法施加。设置有该类碳层的传感器可被变化地应用，并易于适应一定应用的不同需求。该类型传感器也使以可靠和再现的形式来测量参数成为可能。
在其它方面，DE 19 831 372公开了提供有测量碳层并用来控制非阳性连接的垫圈。
发明内容
在本文开头提到类型的起爆传感器中，本发明旨在获得一种测量信号的简单可靠的采集以及它的同等简单可靠的传输。
上述目的的获得是通过本文开头提到的一种用于带有内燃机的电子测评振动传感器的起爆传感器，该振动传感器是以压阻无定型碳层的形式实现，该碳层厚度在10nm到500μm之间，特别在10nm到20μm之间，其中，该碳层被刚硬地加到基体的表面部分上，其特点在于：所述起爆传感器包括基体，所述基体至少包括一个弹簧垫圈，该弹簧垫圈被或可被相对内燃机拉紧，以及在至少一个弹簧垫圈的至少一个表面上涂敷所述压阻无定型碳层。
优点和实施例构成了从属权利要求对象。
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。根据本发明，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实际上形成了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，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。当利用根据本发明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。
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4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5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，使用的弹簧垫圈由垫圈7组成，该垫圈7实际上是以平夹式弹簧垫圈4的形式实现的。
原则上，也可被想得到的是，将金刚石结构碳层5分别加到弹簧垫圈4，7的两侧上。
图3示出一起爆传感器，其中使用了特殊螺丝8来拉紧弹簧垫圈4。与螺丝8一体的限位环9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8时，如图4所示的相应旋上安装本体可以省去。
在根据图5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10。
