Red Bull Racing seamless gearbox

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Double clutch gearboxes are not allowed. Constant variable transmissions are not allowed. Seamless automated manual gearboxes are allowed.

If you guys find technology more interesting than pumping up the other posters, then get on subject, and do tech talk. I have a few answers, do you have any real questions? If so, I'll talk back!

Or, you could just post wind-up BS?

Why do we have to guess the right questions? If you have useful info, why don't you just share it with us? That's what these forums are all about.

It´s been a while since I visited this topic... and damn, is this some sort of battlefield?
Let´s just stop occusing eachother and go back to the thing, let´s keep the good mood that the forum is known about :D

I knew that CVT is banned that´s why I was suprised :)
I have that Twitter -thingie now!

Current F1 transmission isn't CVT or DSG...

It is a AMT (Automated Manual Transmission), just like BMW SMG、Ferrari F1、Lamborghini E-Gear、Audi R-Tronic...etc


A few weeks ago, I found a video...it's BMW Sauber - Willy Ramph talking about the chassis and something else

You can see the video...http://0rz.tw/5b2CH

The lower shaft is input (from clutch), the upper shaft is output (to differential & final drive)


There is a servo-mechanism above the output shaft...

I don't know whether it is hydraulic controlled or use other methods ??

The servo-mechanism rotates itself, the groove on servo-mechanism allows "gear-select fork" to engage the appropriate gear.


Obviously, this transmission shown on video is not seamless...it use dog-gear synchronizer. http://0rz.tw/d32DJ

Seamless is a mechanism to take place of dog-gear synchronizer. http://www.zeroshift.com

Sorry my mother tongue isn't English, May you can understand. :D

Sorry, I didn't mean to insult anyone. Here's what I know, for what it's worth:


Two Clutch Systems - It has two geared shafts and one driven shaft. It also has two clutches. The gears on shaft "A" are 1, 3, 5 and the gears on shaft "B" are 2, 4, 6, and these shafts are parallel. The odd and even gears are matched. The chosen gear is powering the driven shaft while the other gear is along for the ride.

In first gear, clutch "A" is engaged on shaft "A" while clutch "B" is disengaged on shaft "B". So, shaft “A” is moving at its pace based on the ratio of gear one, and is powering the driven shaft.

Shaft “B” is moving at a faster pace than "A" based on the ratio of gear two, but is not driving anything. Shifting occurs, clutch “A” disengages and clutch “B” engages. Gear two is now powering the driven shaft.

Seamless shifting involves one gear shaft and one clutch. The earliest systems had 3 pairs of sliding bullets that moved out of the first gear dog and into the second gear dog. The "A" bullet would slide out of the first gear dog at precisely the same time that the "B" bullet would slide into the second gear dog. The shape of the bullets allowed one to disengage while the other positively engaged. The torque interruption necessary to facilitate this unloading and loading was milliseconds.

The newest systems are said to have rings rather than bullets..

On the other hand, constant velocity transmissions are similar to the derailleur on a multi-speed bicycle. A belt driven cone changes output speed as the belt moves down the cone through unlimited gear ratios. Banned!
