摘　　要：针对汽车厂家和用户对离合器操纵系统性能的要求越来越高,通过分析离合器分离轴承的压紧力和行程变化,结合离合器操纵系统传递特性,建立了离合器液压操纵系统准静力学模型,得到了离合器操纵过程中踏板力和踏板行程变化曲线。通过离合器液压操纵系统性能试验台对理论模型进行了试验验证。结果表明:在踩下踏板开始和松开踏板结束的小段过程中,理论值略高于试验结果,在其他踏板运动过程中,理论值略低于试验结果,但两者的曲线变化趋势基本一致,从而为优化离合器和研究离合器操纵系统特性奠定了理论基础。Aiming at the high requirement of the improvement on the clutch actuation system characteristics,the release load and release travel on the clutch release bearing are analyzed and the clutch actuation system transfer characteristics is combined,the statics model of clutch hydraulic actuation system is established,then the characteristic curve of the pedal force and the pedal stroke is obtained.And the theoretical model is verified by clutch hydraulic actuation system characteristic test bed.The results show that the theoretical value is slightly higher than the test results at the start of pedaling and the end of releasing pedal.At other moments,the theoretical value is slightly lower than the test results.But the two curve change trends are basically similar.So,it provides some theoretical knowledge about the clutch structure optimizing and clutch actuation system characteristic study.
