摘要
针对制动拖滞会降低制动器的使用寿命,增加整车油耗的问题。以盘式浮动制动器为研究对象,对拖滞因素进行了概述,并对断面跳动和零部件刚度两方面的因素作了深入分析。理论上,得出了端面跳动与制动器工作间隙的关系;通过对制动器进行受力变形分析,得出了零部件变形量与拖滞参量的关系。建立了考虑两方面影响因素的仿真模型,并通过试验结果验证了模型的可行性,由仿真得出了制动器主要部件的刚度及制动盘的端面跳动对拖滞的影响规律。此仿真方法可以用于分析拖滞因素及在设计阶段评估拖滞。
Due to brake drag shortening service life of brake and increasing vehicle fuel consumption, the drag factors were summarized, with floating disc brake as the research object. The factors lateral runout and stiffness of brake partswere analyzed deeply. Theoretically,the relationship between lateral runout and brake working clearance was obtained. Through analyzing deformation and force of brake parts, the relationship between deformation and drag parameter was obtained. A simulation model of two main influence drag factors was established, and its feasibility was verified by the test results. Through the simulation, the influence laws of main components stiffness and lateral runout on brake drag were obtained. This simulation method can be used to analyze the drag factors and evaluate the drag in design phase.
