摘要
利用离合器踏板特性分析系统,测试了某轿车冷车、热车及离合器生命周期末期时不同发动机工作转速下离合器的踏板特性。结果表明,随发动机转速的增加,离合器分离过程的踏板特性曲线呈整体下移趋势,离合器的最大分离力降低,同时离合器回位过程的踏板特性呈整体上移趋势,离合器踏板的迟滞力减小,回馈效果变好;与热车状态相比,离合器冷车状态时的最大分离力较高,且迟滞力略高;与新离合器相比,处于生命周期末期的离合器的最大分离力和迟滞力均增加约50%。
Using clutch pedal analysis system,clutch pedal characteristics at different engine speed are tested under cold and warm condition as well as clutch in its end of life cycle.The results show that： with the increase of engine speed,the disengage curve of clutch pedal characteristic moves downward,the maximum disengagement force decreases,at the same time,engage curve moves upward and hysteresis of clutch pedal is decreasing,feedback effect becomes better;compared with warm vehicle condition,the maximum disengagement force and hysteresis force in cold vehicle are bigger.Compared with new clutch,there are about 50% increases in maximum disengagement force and hysteresis force of clutch pedal at the end of clutch life cycle.
