石棉摩擦材料(以下简称摩擦材料)广泛应用于工程、石油、铁道、飞机、汽车和拖拉机等各类机械的摩擦离合器和制动器上。由于其应用范围很广,特别是各类机械的结构不断发展,其使用工况十分复杂,对摩擦材料的要求也越来越高。本文就摩擦材料的重要特性——摩擦特性加以论述。一、制动效率制动效率就是指在各种速度下,各制动压力(气压或油压)下的制动能力(即制动力矩)的大小。通俗讲,刹车灵就是指制动效率高。而且在同一个制动压力下,不同速度下的制动力
Asbestos friction materials (hereinafter referred to as friction materials) are widely used in engineering, petroleum, railway, aircraft, automobiles and tractors and other types of machinery friction clutches and brakes. Due to its wide range of applications, especially the continuous development of the structure of various types of machinery, the operating conditions are very complicated and the requirements for friction materials are also getting higher and higher. In this paper, the important characteristics of friction materials - friction characteristics are discussed. First, the brake efficiency Braking efficiency refers to the speed at various speeds, the brake pressure (pressure or hydraulic) under the braking capacity (ie, braking torque) size. Popular speaking, Brake Ling refers to the braking efficiency. And in the same brake pressure, braking force at different speeds
