摘要/Abstract

摘要： 采用盘-盘型摩擦试验机（WAZAU）评测了丁基三苯基硫代磷酸酯（IR 232）含量对自动传动液（ATF）抗颤性的影响；针对JASO M349标准摩擦因数-转速（μ-v）曲线分析方法的不足，创建了摩擦因数-长磨耐久时间的（μ-t）分析方法。结果显示：IR 232对ATF抗颤性有较大影响；虽然采用JASO M349标准的μ-v曲线分析方法可以判断出IR 232添加量的优化范围，但无法准确判定油品抗颤性失效的具体时间；而采用μ-t曲线分析方法，可以准确判断出ATF油品失去抗颤性的时间；对于不同IR 232添加量的ATF A~F共6个油品，ATF C的抗颤性最优，在长磨耐久测试后65.7 h开始失去抗颤性，说明IR 232的最优添加量（w）为0.3%。

Abstract: The effect of the content of butyl triphenyl thiophosphate (IR 232) on the anti-shudder performance of the automatic transmission fluid (ATF) was evaluated by the disc-on-disc tribo-test-rig (WAZAU). In view of the deficiency of the friction coefficient-velocity (μ-v) curve analysis method JASO M349 standard, the friction coefficient-friction endurance time (μ-t) curve analysis method was developed. The results showed that IR 232 had a great effect on the anti-shudder performance of ATF. Although the optimal range of IR 232 addition could be determined by using JASO standard μ-v curve analysis method, the exact time of anti-shudder performance failure could not be determined accurately. By using the method of μ-t, the precise time when ATF lost its anti-shudder performance could be accurately determined. Among the samples ATF A~F with different dosage of IR 232, ATF C showed the best anti-shudder performance and begun to lose anti-shudder performance at 65.7 h after the durability test, which indicated that the optimal dosage of IR 232 was 0.3%.
