现如今的摩托车基本都用液压刹车,但有些车友对液压的理解有疑惑,本篇就液压刹车作些浅显的解析。&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;液压刹车有上泵和下泵,其实就是一个力量放大器,上泵苗条,下泵粗壮。</p><p style="clear: none;white-space:

style="clear: none;white-space: normal;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;有得必有失,上泵力量虽小但行程大,下泵力量大但行程小。</p><p style="clear: none;white-space: normal;"></p><p style="clear:

powered-by="xiumi.us"><p style="white-space: normal;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;其实这是一个初中物理问题,简言之,下泵活塞面积是上泵多少倍就是力量大多少倍(对向活塞计算单边),通常放大10~17倍为宜。</p><p style="white-space:

style="clear: none;white-space: normal;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;这里要指出一点,刹车泵上标明的14RCS、17RCS、19RCS是什么意思呢?某些车友称之为磅数,有些网店标的是压力,这明显是误导!这数字是活塞直径,分别是14、17、19mm,据上述原理,上泵数字越小,下泵及卡钳的压力越大,要增加卡钳力度,通常把下泵换大即可,如果上下一起换大要看活塞面积比的变化结果,比如上泵大1.5倍,下泵也大1.5倍,那就等于没换,如果上泵换大那还不如不换,如果单碟改双碟,那上泵是要加大的,毕竟上下泵的力不能无限放大,下泵过短的行程是无法夹紧刹车盘的。</p></section></section><section

powered-by="xiumi.us"><p style="white-space: normal;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;说下直推泵和侧推泵,据帕斯卡原理,液压力的传导是各个方向均等,如下图所示。</p></section></section><section style="width:

powered-by="xiumi.us"><p style="clear: none;white-space: normal;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;当然,还有一点就是刹车手把的杠杆比例也会影响上泵的推力,这跟动力臂和阻力臂的比例有关,不同的杠杆比例选用不同的上泵,杠杆越大上泵也越大,反之亦然。</p></section></section><section style="width: 0px;margin-right:

轮胎作用>刹车,换个好胎还是很有必要的。
