Abstract—

The article suggests a disc brake design with carbon friction materials (CFMs). The principle of the method is to create two friction units in the disc brake with materials placed in them that have different frictional properties. The two friction units are created by separating the brake disc with a thermally insulating screen. One friction unit (friction unit A) has CFMs installed having a low friction coefficient in the initial temperature mode and a high friction coefficient at a temperature of 300°C or higher. The other friction unit has a premium-class car block (CB) and a steel disk (35GS steel) the friction coefficient of which does not depend on temperature (friction unit B). The experiment conducted justifies the creation of a disc brake based on the described principle. The experiment was carried out on a testing bench that simulates the interaction of the disc brake as per the load-speed criteria. The testing bench creates conditions for a constructive separation of the brake disc into friction units A and B. As an example of two friction units: CFM–CFM (friction unit A) and CB–steel 35GS (friction unit B). The experimental performance of the friction coefficient versus temperature obtained on the testing bench in relation to friction units containing friction materials CFM–CFM and CB–steel 35GS showed that the friction coefficient of the disc brake takes high values in the entire range of temperatures tested during braking. The article offers a promising design of a disc brake with thermally insulated friction units. The design consists of two brake discs and a central part, which is thermally insulating. All parts are glued together.

碳摩擦材料盘式制动器设计

摘要:提出了一种碳摩擦材料盘式制动器的设计方案。该方法的原理是在盘式制动器中创建两个摩擦单元，其中放置具有不同摩擦特性的材料。这两个摩擦单元是通过将制动盘与隔热屏分开而产生的。一个摩擦单元(摩擦单元A)安装了cfm，在初始温度模式下摩擦系数低，在300°C或更高的温度下摩擦系数高。另一个摩擦单元为高档车块(CB)和摩擦系数不随温度变化的钢盘(35GS钢)(摩擦单元B)。实验证明基于上述原理制造盘式制动器是合理的。实验是在一个试验台上进行的，该试验台按照载荷-速度准则模拟盘式制动器的相互作用。试验台为制动盘建设性地分离为摩擦单元a和b创造了条件。作为两个摩擦单元的例子:CFM-CFM(摩擦单元A)和cb -钢35GS(摩擦单元B)在试验台上获得的摩擦系数随温度变化的实验性能表明，在制动过程中，包含CFM-CFM和cb -钢35GS的摩擦单元的摩擦系数在整个测试温度范围内都有较高的值。文章提供了一个有前途的设计与隔热摩擦单元盘式制动器。该设计包括两个制动盘和一个中心部分，它是隔热的。所有的部件都粘在一起了。
