Abstract
一种混合制动组件，它既装有一树脂粘合的金属摩擦垫件，又装有一树脂粘合的非石棉、非金属摩擦垫件以及车辆制动时同时促动两摩擦垫件的液压缸/活塞部件。
Description
本发明概括地讲涉及一种属用于国内道路交通工具类型的制动装置，特别涉及一种应用两种不同类型摩擦垫件以获得制动装置及制动系统性能改善的制动系统装置，还涉及制动装置中所采用的摩擦垫件。
美国有关道路交通工具设计及制造的要求极大地受到美国交通部颁布的规则的影响。因此，改进的制动装置的研制已有相当长的时期。制动器设计者更多地注意满足政府对交通工具制动系统的操作要求，特别是交通工具刹车距离技术要求的规定。这导致公布了至少一种已知的应用由不同摩擦材料制成之两相对制动器摩擦垫的制动装置结构。特别是，美国No.3,856,120专利公布了一种由我本人和PatrickA.Thesier共同创造的道路交通工具盘状制动装置发明，该装置既包含一半金属摩擦垫，也包含一有机物摩擦垫，有机物摩擦垫包含占体积20～60％的石棉纤维。
但是，为了避免制动装置摩擦垫制造和使用中含有石棉成分，有必要设计新的摩擦材料组成。在此过程中我发现，使用新的特殊摩擦垫材料组合可实现如增强冷制动和减少噪音产生的新的制动装置和制动装置操作性能。
因此，本发明的目的在于提供一种车轮制动装置，该车轮制动装置中不含有石棉摩擦垫件，而是包含一半树脂粘合金属摩擦垫件和一半非石棉、非金属摩擦垫件。
本发明的另一目的在于提供一种可提高制动性能的树脂粘合金属摩擦垫件。
本发明的又一目的在于提供一种非石棉、非金属摩擦垫件。
根据本发明的一个方面，提供一种车轮制动装置，它包括：具有一金属背板件和一连在背板件上的树脂粘合金属摩擦垫件的第一产生摩擦摩擦垫组件；具有一金属背板件和一连在背板件上的树脂粘合非石棉、非金属摩擦垫件的第二产生摩擦摩擦垫组件，其中所述树脂粘合非石棉、非金属摩擦垫件由约10～25份除石棉纤维颗粒外的纤维颗粒、约8～20份树脂粘合剂颗粒、约2～18份碳质颗粒、约2～20份磨料颗粒、约20～40份填充物颗粒及约5～20份摩擦颗粒组成，上述所有份比例为重量百分比；用于同时驱动上述第一及第二摩擦垫组件以在上述树脂粘合金属垫件和上述树脂粘合非石棉、非金属摩擦垫件的表面产生摩擦的装置。
根据本发明的另一方面，其中，树脂粘合金属摩擦垫件由约25～60份金属颗粒、约5～15份树脂粘合剂颗粒、约10～25份碳质颗粒、约0～8份磨料颗粒、约3～25份填充物颗粒及约0～10份摩擦颗粒组成，所有上述份比例为重量百分比。
根据本发明的又一方面，提供一种树脂粘合制动摩擦垫件，由约25～60份金属颗粒、约5～15份树脂粘合剂颗粒、约10～25份碳质颗粒、约0～8份磨料颗粒、约3～25份填充物颗粒及约1～10份摩擦颗粒组成，所有上述份比例为重量百分比。
根据本发明的又一方面，提供一种制动摩擦垫件，由约10～25份除石棉纤维颗粒外的纤维颗粒、约8～20份树脂粘合剂颗粒、约2～18份碳质颗粒、约2～20份磨料颗粒、约20～40份填充物颗粒及约5～20份摩擦颗粒组成，所有上述份比例为重量百分比。
通过使用我的发明还能实现其它制动装置优点。
为了改进制动装置冷制动并使其具有降低噪音的操作性能，我设计了一种盘状制动装置，该装置既包括一半金属摩擦垫，又包括一相对的非石棉、非金属摩擦垫，每个垫组成部分是由用普通方法由树脂粘合成一整体的半金属摩擦垫包含重量比为25～60％的金属颗粒/纤维。非石棉、非金属摩擦垫包含重量比为10～25％的纤维颗粒，纤维颗粒来自玻璃纤维、陶瓷纤维、耐热纤维(thermalfibers)、聚丙烯腈纤维、芳族聚酰胺纤维及钢纤维的族系，钢纤维在非石棉组成总纤维含量中占较小比例。
制动装置工作时，相对的半金属摩擦垫和非石棉摩擦垫基本上同时与协同操作的制动装置转子接触，以在制动系统宽的环境温度范围内体现上述的操作优点。
图1为车轮制动装置局部立剖面示意图，表示与制动装置转子件相配合的本发明的装置摩擦垫元件。
参照图1的示意说明，本发明混合制动装置的优选实施例一般标为10，它基本包括一卡规形定子件12、一转子件14及一对相向制动摩擦垫组件16、18。制动装置工作时，由操作者操作一般标为20的现有技术中的液压缸/活塞组件使组件16、18各自与转子14的相对面17、19构成摩擦的面-面接触。转子14由于和与其结合的车轮轮毂存在固定关系，因而随车轮绕轮轴转动；卡规形定子12由于与车框(未示出)的机械连接而在车辆刹车时不能随转子14转动。
在优选制动装置实施例10中，每个摩擦垫组件16、18都分别装有一金属背板件22、24，还分别装有一摩擦垫件26、28。按照这里的说明，摩擦垫件26、28由不同的产生摩擦材料制造，摩擦垫件26由树脂粘接的金属组分制造，而件28由树脂粘接的非石棉、非金属组分制造。垫件26、28一般由已有的硬粘合剂或由如铆钉或螺栓(未详述)的机械紧固装置分别与各自背板件22、24连接。
下面表1详细介绍的混合物1是一用于制造树脂粘接金属摩擦垫件26的颗粒组分的例子，而表2详细介绍的混合物2是一用于制造树脂粘接非石棉、非金属摩擦垫件28的颗粒组分的例子。表中给出的所有组成比例都是重量百分比。
表1
成分 混合物1配方 成分范围金属/颗粒/纤维 55 25-60树脂粘合剂颗粒 10 5-15碳质颗粒 18 10-25磨料颗粒 4 0-8填充物颗粒 8 3-25摩擦颗粒 5 0-10总计 100.0
表2成分 混合物2配方 成分范围纤维颗粒 12 10-25树脂粘合剂颗粒 12 8-20碳质颗粒 12 2-18磨料颗粒 15 2-20填充物颗粒 39 20-40摩擦颗粒 10 5-20总计 100.0
在制备用于模制本发明摩擦垫件的组合混合物过程中，我优选纯净的或改进的给定的树脂粘合剂酚醛树脂颗粒为给定的树脂粘合剂。所需的碳质颗粒优选石墨颗粒、焦炭颗粒或甚至是煤颗粒。对于磨料颗粒组分，我选氧化镁、氧化硅、氧化铝或硅酸铝及类似颗粒。对于填充物颗粒组分，我优先从重晶石颗粒、碳酸钙颗粒、磨石(硅酸石灰石)颗粒及类似材料的族中选择。如在用于模制摩擦垫件26或摩擦垫件28的混合物的制备中使用摩擦颗粒，一般为颗粒轮胎外皮或为制动器制造业中熟知的摩擦组分。另外，用于制造金属摩擦垫件26的混合物中的金属颗粒选自由氧化铁粉末、铁粉和钢纤维组成的族系。
摩擦垫件28的特征为非石棉、非金属摩擦垫。在混合物2配方中，我基本上使用纤维颗粒而不是石棉来在组合制动系统制动装置中帮助提高增加制动摩擦的能力，特别是在初次或第一次制动时以及当系统在环境温度低于大约华氏零度运行时。作为替代纤维颗粒，我一般从包括玻璃纤维颗粒、陶瓷纤维颗粒、热(如玻璃纤维和矿物纤维)纤维颗粒、聚丙烯腈纤维颗粒、芳族聚酰胺纤维颗粒及少量钢纤维颗粒(即少于5％)的族系中选择。虽然混合物2组分中可能含有一些钢纤维颗粒，但由于在总组成中少量的纤维颗粒成分与表1组分或其它已知的金属或半金属摩擦垫摩擦材料中含有的金属颗粒量相比仅占很小比例，所以该摩擦材料仍认为是非金属的。
在一种制造上述摩擦材料组分的方法中，我优选将称量过的所需量的颗粒混合物均匀分布于预热到大约华氏320度的摩擦垫模具的摩擦垫腔中。然后分散的材料在模具摩擦垫腔内被压制到等静压大约为2000磅/英寸2，且过1分钟、2分钟、3分钟使腔体排气。接下来模具压力最好增加至在被压混合物中产生强度为大约4000磅/英寸2静压力，并且这个强度的压力保持至少约2分钟。最后，将这样压制并部分加热的预成形件从模具中取出，按着传送到处理炉中，通过将摩擦垫材料温度在3小时内线性提高到约华氏300度，再将加热的预成形件在华氏300度保温另外4小时进行热处理。根据加工的混合物组成颗粒、工件形状、工件尺寸改变此处总结的摩擦垫件的制造方法是可行的。
其它材料、工件形状、工件尺寸，包括其它功能相当的成分，可用于进行权利要求保护的发明的实施。
由于在不背离以上所述发明范围情况下可对上述系统和装置作某些改动，所以说明中包含的或附图表示的所有内容都应理解为说明性的而没有限制之意。
