因為跟我上一篇沒啥關係
所以另外發一篇來問...
之前曾經想過,FZR原廠配備雙小碟,NSR原廠配備單大碟 (我指前煞)
學過物理都知道,ff = k * N (摩擦力 = 係數 * 正向力)
而碟煞又是力矩的概念,力臂越長(碟盤越大)力矩越大
問題來了:
1.單一卡鉗跟對二卡鉗,不用說是對二效果較好
但是以物理的看法是因為正向力變大(雙卡鉗施力)所以摩擦力增加?
因為磨擦力跟接觸面積無關...所以是正向力增加,對吧?
2.以FZR跟NSR來做比較,誰的煞車制動能力比較好呢?
(記得看過人家說FZR制動力不是很好,所以FZR制動比較弱??)
3.雙碟會不會因為煞車力量比較均勻(左碟右碟)所以比單碟好?(左單或者右單)
第二部分我想問的是冷卻
CBR150原廠17ps,改管後21ps
酷龍150 14ps
兩台都是150的車,CBR動力高,基本上不意外(畢竟是Honda比Kymco)
不過我想了想,150的車,動力基本上不會相差太多才對
即便Honda技術領先,也不至於換了一根管動力就比酷龍動力高5成
所以我想,跟水冷系統是否有關?
NSR也是150cc,一樣配備水冷,也是20ps起跳的車(雖然2T比4T這樣看不準)
但是我看到他們的共通點就是水冷
許多的大型重型機車也有配備水冷
所以我想問,水冷對於動力是否有幫助?
謝謝
