摘要
针对汽车鼓式制动器在制动过程中产生的噪声问题,进行了故障再现试验,结合制动鼓工作面的纹理特征进行噪声机理分析,确定制动器制动蹄片的轴向运动干涉是制动噪声形成的内在机制;基于螺纹原理建立了制动器蹄片轴向力学模型,得到整车制动系统参数与张制动蹄片轴向轴向力的关系,揭示制动鼓工作面粗糙度及机加工进给量对轴向力的影响规律,在此基础上提出鼓式制动器参数设计控制模型,为制动鼓结构设计及制造工艺参数设计提供依据。
For the brake noise on brake drum,the issue reappearing test was conducted,and the axial movement of the brake shoe forcing the intrinsic reason of this noise formation was determined according to analyzing the effect characteristic of the texture distribution on the brake drum surface. Base on the thread principle,the axial mechanic model of brake shoe was established. The relationship of vehicle brake parameters and axial force of brake shoe was received,and the influence of drum surface roughness and feed rate for this axial force was revealed,and putting forward the control model of brake drum design parameters,which providing the deign reference for the structure and process parameter design of brake drum to avoiding this noise.
