不過內盤材質 我知道某些國內是用鋁合金 這跟 使用中碳鋼 有和差別
用鋁合金 ,
BREMBO 的說法
Why use a two-piece "floating" disc assembly?
There are several reasons that a two-piece floating disc assembly is of benefit.
First, by using an aluminum bell for the hub section of the disc saves a great deal of weight
. Since this is both rotating and unsprung, it benefits the acceleration, braking, and handling of the vehicle.
Secondly, it is better able to handle the large temperature changes that a brake disc experiences.
During severe use, temperature variances become present in a one-piece disc and generally cause warping of the disc. This not only results in vibration of the vehicle, and pulsing of the brake pedal, but also pushes the pistons farther away from the disc. In a two-piece floating disc assembly, the iron disc heats up more uniformly, and the controlled float which is present allows for the differential expansion of the very hot brake disc, and the relatively cool aluminum bell. This allows the disc to be used under severe conditions without having a detrimental effect.
可用CHROME翻下
個人看多國內的浮動盤...
不是很不耐用 (偷工減料)
就是貴到爆...
6061 VS 7075 VS 7075-T/T6 價位和加工本來就差很大 (都鋁合金喔)
光鋁合金就能寫很多了
浮動的紐扣我更不敢多說... 有些不會動,有些動太大... ![[觀念]碟盤的材質、硬度與實際應用的概略講解4925](static/image/smiley/jorsindo/em39.gif) |
