這個帖話明是 2011年新 F1 賽季, 季前試車我只打算 post 2011年新車相, 有份參與試車的2010舊車變得冇乜意思. 所以本來唔想 post 威廉士車隊的 FW33 住, 因為它講明今次試車只是拿架 interim car, 兼未有新車花 (只噴上全深藍的所謂車隊傳統色). 不過佢肯公開自己架車的新轉變播. 就即本睇睇 :-
Williams has revealed that creating the smallest gearbox in its Formula 1 history was one of the key factors that helped it create such a unique rear end to its new FW33.
Williams has produced a very aggressive design at the back of its car - with the sidepods and engine cover narrowed down to the minimum to help airflow at the back of the car.
Williams technical director Sam Michael said,
"The main changes revolve around the gearbox casing and location of the differential.
The target is to have as much clear air flow to the rear wing assembly as possible by clearing all the area to the rear lower wing because it is a performance differentiator now.
You've got to have the underside of the rear lower wing completely free, so we took the decision to lift the top wishbone and the track rod and go to a Z-bone layout – which was commonly used in the early 90's – to get that all above the underside.
It means that all the weight is in line with the trailing edge of the legality box, so you are nowhere near the underside of the rear lower wing, and it's completely free airflow.
The push to get the airflow tidied up at the rear of the car meant that a pull-rod suspension configuration was a must. As it means there's less blockage to the rear
It doesn't matter what you do with a pushrod, even if it is swept forwards or backwards, you've got a load going into the rear lower wing, whereas a pull rod is completely out of the rear lower wing. That was an easy decision.
擺明同法拉利打對台喎
The other thing was to clear the centre of it by lowering the gearbox. We dropped the top section as much as we could and it is the smallest box we've ever made with the most extreme driveshaft design --- quite a big driveshaft angle.
大家可留意圖片中的金啡色的驅動軸 (driveshaft) 的確幾大角度. 其缺點是令萬向節 (和尚頭) 承受好大壓力.....要注意 reliability 喎!
再爆 Williams 的.....
昨天首日試車架 FW33 的 KERS 出了毛病. 當時我已好好奇, 它用乜 KERS 系統呢?
今日受訪時確認了它是用 battery pack 即是主流設計的 KERS, 還記得威廉士在2009年吹到恆話研發用 fly wheel 的 KERS 嗎??? 結果2009成年都冇到 KERS, 兩年後.....提都唔提....我就叫它做八萬五飛輪KERS罷
