第一次见到这样的刹车盘 

[img]file:///C:\Users\nessus\Documents\Tencent Files\54654937\Image\%NB27ZM9Z@0%2]NOH{][LCQ.jpg[/img][attachment=410923] 首先有两个卡钳，而且盘还不是圆的？为什么要设计成这个形状？

看看热闹，具体原理不懂

我猜rotor不是圆的原因是因为毕竟它是旋转部件。我的initial prediction是这种设计不但轻量化，而且把重量越靠近圆心的话越有利。

ya but the additional caliper is sprung weight... hahah

The caliper doesn't spin. The rotor, meanwhile, experiences "centrifugal" (very shaky term) force as it spins. The physical interpretation is similar to swinging a bucket full of water with a rope where when exceeding a certain threshold of tangential velocity, the water doesn't spill out. (omitting all the physics and math here) The odd shape of the rotor is probably for: 1) weight reduction - skimping bits and pieces of metal off the rotor 2) cooling purposes with a new geometric setup. edit: oh i found this article on Modi-Auto. Although the force analysis is very basic, I think it still gives a fair explanation. [url]http://modify.modi-auto.com.cn/planning/1084/7150.html[/url]

I'll take 15" slotted discs with 6 pots single caliper instead, thank you very much.

都是高手啊！！ 这车确实是drift用的。

這種叫floating rotor, 機車上比較常見
