Description

具有力传感器的机械的部件
技术领域
本发明涉及一种用于车辆的机械的部件，其包括具有表面的测量区域和分配给测量区域的力传感器，所述力传感器用于检测加载部件的力。本发明还涉及特别的力传感器的应用。
背景技术
在申请人的序号为10 2013 213 672.2的较早申请中公开了具有力传感器的机械的部件，其中，机械的部件在优选的实施方式中被构造为摆动支座并且力传感器被构造为弯曲弹性的变形元件，其在测量区域内与摆动支座形状配合地连接。在此，变形元件用作在被构造为杆形的摆动支座中的机械负荷的放大器，在其中尤其出现拉应力和压应力。由压应力和拉应力产生的摆动支座的压缩和伸展被传递到构造为弧形的变形元件上。由磁性材料制造而成的变形元件的机械变化伴随着磁场的变化，这可测量并且可转换为电信号。变形元件的变形由适合的传感器装置、优选地在执行磁场测量的情况下进行检测。
通过DE 10 2011 117 519 A1已知具有力传感器的挂车挂接装置，其中，力传感器优选地被构造为应变测量器并且设置在挂接钩的表面上。
发明内容
本发明的目的在于，充分利用机械的部件上的力测量的其它潜力。
根据本发明的机械的部件用于车辆，该机械的部件包括具有表面的测量区域和分配给所述测量区域的力传感器，所述力传感器用于检测加载所述部件的力，其中，所述力传感器包括施加到所述测量区域的表面上的由碳纳米管构成的层，下面称为CNT层，其特征在于，所述机械的部件为底盘的摆动支座，所述摆动支座通过球铰链与具有柄的球形销连接并且所述CNT层施加到所述球形销的柄上。
根据本发明，在所述CNT层和所述柄的表面之间布置绝缘层。
根据本发明，所述CNT层形成导电连接并且具有至少一个输入接触部以及至少一个输出接触部。
根据本发明，所述输入接触部和所述输出接触部通过电导体与评估电子装置和电源连接。
根据本发明，所述CNT层为附着在所述柄的表面上的漆层。
根据本发明的第一方面规定，力传感器被构造为施加到测量区域的表面上的、由碳纳米管(CNT)或碳纳米微管构成的层。材料碳纳米管(下面称为CNT)本身已知：其为由碳构成的微观上很小的管形的组织。根据本发明使用的CNT材料是导电的并且此外在机械负荷的情况下、例如由力作用引起的伸展和压缩的情况下其电阻改变。根据本发明，利用该效应，以将CNT材料用作力传感器的感测元件。在此，CNT材料作为层施加到受负荷的部件的表面上。这具有如下优点：感测元件直接位于部件的力流中，即，受负荷的部件的伸展或压缩直接被传递到附着在部件表面上的CNT层上。在此，获得准确的力测量。此外，有利的是，包含在适合的结合剂、优选呈漆的形式的结合剂中的CNT材料可简单地运用到部件上，优选地通过涂覆。
根据一种优选实施方式，在CNT层和部件的表面之间布置绝缘层，其使导电的CNT层相对于导电的部件绝缘。也可以在施加绝缘层之后涂覆CNT层。
只要机械的部件由不能导电的材料制成，优选地由塑料制成，绝缘层就是多余的。
根据另一优选实施方式，导电的CNT层具有至少一个输入接触部和至少一个输出接触部。如已经提及的，通过测量由部件的机械负荷引起的CNT层的电阻变化，进行力测量。在接触部之间，CNT层优选特别地被恒定的电流流经，其中，在电阻变化时产生电压变化，其作为信号可被测量且可被评估。替代地，即使在电流可变、不恒定的情况下也可进行测量。
根据另一优选实施方式，输入接触部和输出接触部通过电导体与评估电子装置和电流源连接。通过评估电子装置，电信号、特别是电压信号转换为代表所测量的部件负荷的信号。
根据另一优选实施方式，CNT层被构造为附着在表面上的漆层。CNT材料因此包含在漆中，其可以以简单的方式涂覆到部件的测量区域上，并且在此处形成持久的有抵抗能力的层。
根据另一优选实施方式，机械的部件被构造为底盘的摆动支座，其中，构造为杆形的摆动支座优选地通过球铰链与球形销连接。CNT层或漆层可以涂覆到摆动支座的表面上或优选地涂覆到构造为圆柱形或略微锥形的球形销上。在后一情况中，产生如下优点：在摆动支座中作用的轴向的拉力或压力引起在球形销中的弯曲应力，且因此被放大。因此，在施加于球形销上的CNT层中出现更强的伸展或压缩(变形)并且因此出现更强的信号，即可以更准确地测量。
根据本发明的另一方面，规定，CNT材料作为用于力传感器的感测元件来应用。因此，得到改善的和简化的用于测量在任意机械部件处的力测量的可行方案。
应理解的是，本发明的以上所述的特征不仅可以按照分别说明的组合，而且可以按照其他的组合或单独地应用，而不会脱离本发明的范围。同样处于本发明范围内的是，引起本发明的各个机械元件的功能的机械翻转。
附图说明
在附图中示出了本发明的实施例并且在下文中对其做详细描述，其中，从描述和/或附图中可得到其他的特征和/或优点。其中：
图1示出了在摆动支座处具有CNT层的根据本发明的力传感器，
图2示出了CNT层的示意图，以及
图3示出了图1中的细节(作为细节示出了图1中的力传感器)。
具体实施方式
图1示出了简化示出的构造为杆形的摆动支座1，摆动支座利用其未示出的自由端部与用于机动车辆的底盘的稳定器铰接地连接。为机械的部件的一种实施例的摆动支座1被加载以轴向力F轴向并且经由球铰链2与球形销3连接，其中，球形销3具有球头3a、柄3b和螺纹区段3c。通过螺纹区段3c，球形销3以未示出的方式与另一底盘部件、例如弹性支柱固定连接。即，静态地观察，球形销3在螺纹区段3c的区域中夹紧，而轴向力F轴向作用到球头3a上并因此对柄3b施加弯曲力矩以及沿径向作用于球铰链的球体的力。因此，在柄3b的区域中产生弯曲应力，其由压应力和拉应力组成。应测量到由拉应力和压应力产生的变形、即在柄3b的表面区域中一方面的伸展以及另一方面的压缩。在柄3b区域中的弯曲应力的值明显比在摆动支座1中的压应力的值高得多，从而产生放大效应。
根据本发明，在柄3b的表面上施加绝缘层4并且在绝缘层4上施加碳纳米管层。碳纳米管层(下文简称为CNT层)根据本发明用作力传感器的感测元件或传感元件，并且设有两个电接触部，输入接触部6和输出接触部7。接触部6、7通过电导体(没有附图标记)与评估电子装置8连接，并且它们通过电连接部(没有附图标记)与未示出的电源连接。在输入接触部6和输出接触部7之间的在球形销3轴向方向上的距离用x表示，即，该区域形成电流流经的CNT层5的测量区域。在该区域中，由于弯曲应力出现相对强的伸展和压缩，其直接传递到CNT层5上，这因而改变其电阻。
图2在示意图中示出了不同CNT结构9a、9b、9c的构造。如已知的，CNT材料由在纳米范围内的最精细的碳微管构成，如图所示，碳微管六边形地布置，即其形成蜂窝式的结构。CNT材料在机械负荷的情况下改变其导电性能。
图3示出了图1的细节，其用虚线的矩形框标记。细节示出了根据本发明的用于力传感器的感测元件的构造。相同的或类似的部件使用与在图1中相同的附图标记。首先绝缘层4、然后CNT层5涂覆到构造为圆柱形的部件(在实施例中为柄3b)上。绝缘层4用于使导电的CNT层5相对于导电的部件3b电绝缘。CNT层5在其轴向错开布置的两端处具有电接触部6、7，其与电导体6a、7a连接。电导体6a、7a与在图1中示出的评估电子装置8连接。CNT层5可以优选地构造为将CNT组成部分结合的漆层，其能够特别简单地涂覆到部件3b上。
根据本发明的具有构造为CNT层5的感测元件的力传感器作用方式如下：在摆动杆1被加载轴向力F轴向时，球形销3的被夹紧的柄3b承受弯曲负荷，使得在柄3b的区域x中出现放大的伸展(在拉纤维中)和压缩(在压纤维中)。这些变形直接被传递到与柄3b的表面固定连接的CNT层5上，使得CNT层5也经受这些变形。这引起CNT层5的电阻变化。CNT层由于接触部6、7优选地被恒定电流流经，使得在电阻变化时出现电压变化，该电压变化被输送给评估电子装置8并且作为信号进行评价。通过电信号，基于机械定律可以计算出在摆动杆1中作用的轴向力。计算出的轴向力的量用作用于车辆主动摆动稳定的初始参数。
