    百米加减档

    百米加减档中几个技术问题-----写出来和大家共同探讨

    问题一:以前一直认为需要将汽车加速到一定的时速才能换档,所以每次换档我都会踩着油门提速,认为速度到了才换档,速度不够不敢换档。然而很多书上给出的档位于车速的对应关系是错误的。而且我问过教练和我的同事,车速多少时可以换档,他们的回答基本相同:不是依据车速来换档。特别是在做百米加减档时。

    问题二:在前面教我的教练不让我猛踩油门,但练习百米加减档时没有告诉我应该将油门踩到底,所以我一直不敢用力踩油门,为了提速只能延长踩油门的时间,结果很难完成百米加减档。

    问题三:压离合,汽车一档起步时不能马上松开离合要压在半离合状态等车走稳在完全抬起离合,从一档换二档时我也是要压离合,延长了换档时间。其实从起步以后基本上不用压离合了,可以比较快的抬起离合,前提就是一定要给足油门。我的同事也告诉过我,如果油门给的大离合就可以抬得快。

    问题四:就是换档的动作了。包括手的动作和脚的动作。只要做到快速,准确,连贯就可以了。

    把百米加减档的过程简单的叙述一下:

    第一:起步的时候当你放下手刹汽车走起来后就应该加大油门,这时你的左脚可能还压着离合,加大油门以后就可以迅速抬起左脚,将离合抬到顶,这时你的右脚继续踩着油门。

    第二:离合抬到顶之后左脚迅速踩下离合器到底同时放松油门,右手将变速杆从一档换到二档,接着抬左脚踩右脚(提示:右脚踩油门要用力),准备换三档。抬左脚时不要猛抬以步行的速度自然起就可。记住从一档换二档开始,以后左脚的动作都是迅速将离合踩到底,等右手将变速杆推到位后即自然抬起,在左脚抬起的同时右脚要用力踩下油门。左右脚的配合和手的动作要协调。

    第三,第四,第五重复第二的动作。在你作加档的动作时不用考虑车速,汽车的速度肯定可以保证你加到五档不会出现剧烈的抖动。要点就是首先保证给足油门,每次换档完成之后果断的做下一个换档动作,中间不要停顿。减档时就容易多了右脚不用做动作,左脚踩三次,抬三次就把档位减下来了。
