: 標題: [影片] Model S P100D上馬力機測試
: 時間: Wed Feb 22 14:23:22 2017
: → DYE: 一般的車內燃機用的變速箱 一兩檔的減速比也很大 02/22 15:44
: → DYE: 輪上的扭力要到一百多也不是難事 (四輪總和) 02/22 15:45
:
: 別搞笑了好嗎?
:
: 要是要這樣說的話Tesla加個變速箱扭力也可以放的更大啊
:
: 況且就以實測來講,連488GTB這種等級的車子實測扭力連P100D的車尾燈都看不到
:
: P100D扭力實測最高127.51 kg.m,488GTB扭力實測最高才86.29 kg.m
:
: 你的"不是難事"說的還真輕鬆
:
: 哪台市售車扭力實測可以簡單的像你說的那樣一百多kg.m的?
我想你沒弄清楚我說的輪上扭力
因為一般人對扭力數值的概念都是曲軸扭力
輪上扭力是經過變速箱放大的
就拿我一台很老的車 手排檔
終傳齒輪是 32/8 一檔齒比是 34/10
所以一檔的總減速比是 13.6 倍
也就是說 一檔的時候 輪上的扭力是曲軸的13.6倍
這台老車有 220nm的扭力
所以在一檔的時候 瞬間輪上能有兩百多公斤的扭力
扭力是可以被放大的 功率才是真的
你或許有疑問
一般的車輪上扭力這麼大
為什麼加速這麼慢
因為輪上扭力這麼高的範圍不長
所以總加速(0-100)並沒有很快
但是瞬間要能打滑輪子還是可以的
當然電動車也可以改齒比來放大輪上扭力
沒有什麼意義而已
因為他不需要
或是說 如果定齒比會減少極速

網路上打筆戰真的要謹言慎行 免得一句話出錯被笑一輩子
