【踭趾 heel & toe】技術分享(轉載)

踭趾有兩種方法:

第一種叫:一腳極力子(single clutch),另一種是2腳極力子(double clutch)
一腳極力子的用法:右腳踩迫力同一時間下左腳踩極力子右腳 踩油波棍落波, 放油,放極力子,最後放迫力. 迫力=brake 波棍=shifter 極力子=clutch
兩腳極力子的用法:右腳踩迫力,左腳踩極力子,落空波,放極力子,右腳踩油及放油,踩極力子,由空波轉低一個波,放極力子,最後放迫力.
所有趾都應該在直線進行,嘗試在入彎前的最後一秒進行.每落一個波做一次,落兩個波做兩次,


轉波(shifting) 般在高性能駕駛時,上波(upshift)通常會比落波(downshift)容易,因為上波時只需讓轉數在紅線或之前以較快的速度換波便可.但轉低波通常是為了在出彎時能讓汽車有較大的馬力及扭力輸出.所以轉低波是在入彎前的直線進行.但因為車在那時候正在減速,所以換波過程同殺車(braking)是同時進行的.但因為引擎速度要配合汽車速度,所以在換波過程中要讓引擎轉數升高,這也是踭趾(heel & toe)的目的.

我都係呀...但其實我到家下都唔明,兩下極力子有咩用???

Double clutching is more important in the old days because
1) there's no synchros between gear cogs
2) synchros at the time were very weak and fragile

Nowadays however it doesn't really matter due to advances in synchro technology.
You can still think that double clutching saves the synchros but sometimes it's just darn more fun to do it.

主要係落低波段(減速) +強扭力& 同時保持引擎轉數

新出的DSG (Direct-Shift Gearbox) 係新一代自動波箱
歐洲同日本車都用, 可能可能會快過手波添

DSG, PDK, DCT, dual-clutch gearbox is bound to overshadow both traditional manual boxes and automatic slushbox in near future. However, nothing beats the rush of good old fashion downshifting with fancy pedal dancing. Ever tried a 4-2 double clutching through a street corner?
