摘　　要：目前评价湿式桥齿轮油摩擦特性的实验方法主要采用高转速、小惯量、低制动压力的实验条件,不能反映湿式桥低转速、大惯量和高制动压力的实际工况。基于湿式桥实际制动工况,开发一种齿轮油摩擦特性评价方法,该方法以摩擦片表面的能量密度表征制动工况的苛刻度,可考察典型工况下制动油压和不同能量密度对油品摩擦特性的影响。采用该评价方法在湿式制动器台架上对普通GL-5齿轮油和湿式桥专用油的摩擦特性进行考察,结果表明,该评价方法对具有不同摩擦特性的齿轮油具有良好的区分性。The experimental conditions that adopt to evaluate the friction characteristics of the wet brake axel gear oils at present are commonly high rotary speed,small inertia and low brake pressure,which can not reflect the actual conditions of the wet brake axel,such as low speed,large inertia and high brake pressure.Based on the actual brake conditions of the brake axel,a test method of evaluating the friction characteristics of wet brake gear oils was established.The test method uses the energy flux of friction plate surface to represent the severity of braking condition,which can investigate the influence of brake pressure and different energy flux on the friction characteristics of wet brake gear oils under typical working conditions.The test method was used to study the friction characteristics of common GL-5 gear oil and specific wet brake axel oil on a wet brake bench tester.The results show that the test method has a good ability to distinguish the gear oils with different friction characteristics.
