I got to see something really cool. I got to open up a modern F1 gearbox and see how it works -- and these things cost upwards of £250,000 each, with the F1 teams spending about £7 million a year on them.
So, of course, I wanted to see and touch the materials and understand exactly how a Formula One car changes gears - from when the driver pulls the paddle through to the gearbox selecting the next gear.
And how they work is actually pretty simple, and, incredibly clever all at the same time.
So, a few weeks ago, I was invited to TDF - a company that restores old F1 cars for private owners - and gives old F1 cars a new lease of life.

I’m always amazed at the narrowness of the gears, considering the power they have to transmit ❤

@SocietyUnplugged 22 күн бұрын

I would disagree if those gears were designed for the V10/V8 era because low torque engines. The hybrid engines have 3 times more torque but it seems that the gears aren't any wider which amazes me as well.

@bertram-raven 22 күн бұрын

This is why they are straight cut. Road car gear are not straight cut to drastically reduce noise but as a result need to be thicker and heavier to prevent skipping and the inherent sideways torque of angle cut gears. Even in multi-thousand Nm industrial engines the straight cut gears are thin - this predates anything similar in F1. Indeed, 1920s busses had them, but they were not seamless and in a "crash" configuration with no synchro drive dogs.

@ramosel 22 күн бұрын

@@SocietyUnplugged But, the gear width is still based on the torque the gear transmits... for strength and durability. 1st gear must transmit much more torque and is wider than say 5th gear which sees less torque (due to gear ratios). I believe beryllium is still banned (health issues) but there are some OMG alloys out there that have taken gear strength to new heights... as well as costs... material and machining. Grumman holds the patents on some very exotic alloys. My contact won't say who is using which ones, only that they are being used. This is where the FIA's stupidity on "cost cutting" becomes painfully obvious. Ideally, in racing, you want just enough strength to last the race and 50 more feet. But the FIA saw that as wasteful and threw in the multi-race engine and gearbox rules. So now the gearboxes (and motors) have to last longer... but to get there they had to go to more expensive materials and machining costs. So no money was saved but the FIA can put on their addlepated "Green" smile.

@bobolulu7615 22 күн бұрын

The shaft spacing, when wider apart, means the chord line of power introduced to the gear teeth, is flatter and the force is therefore along a thicker part of the gear tooth. Also there are several teeth always in engagement, lowering the amount of torque loading on each gear tooth.

Considering the amount of power transmitted, I'm most impressed by those drive dogs which take as much force as anything in there and are the smallest part. Impressive stack of friction discs in the clutch of such small diameter.

My first career many years ago was as a heavy equipment mechanic....I used to remove these massive transmissions from time to time for repair. Its very surprising to me to see how simple and light the F1 transmissions are and that they can withstand the shifting at such high revs and not blow apart. I wonder, how long do they actually last ?

@chiefdenis 21 күн бұрын

They can last 6 races (p3 to quali, to race) or more, ~400km per weekend = ~2400 high stress kms.

@ScottDukesRealEstate 17 күн бұрын

You may remember they pointed out an oil pump early in the program which helps cool the transmission and insure better oil distribution/volume compared to similar transmissions that just have the gears sitting in the oil to distribute it. Most likely helping longevity of the trans. Something I didn't realize was the two shift drums. I thought they had two separate clutches and gear systems that were independent of each other. One for odd and one for even gears. This way they could shift independently. Shifting delay between the two could then be determined electronically and easily tuned. With the approach used in the video requires just another drum like a self playing piano. Less complicated and less weight. Very cool.

Gears used to be heavy and clunky. Today they are much lighter and have better torque. The manufacture of gears is a brilliant world in itself. Just by using much better quality controls and technology, you can improve the weight, service life and efficiency immensely! I love this job!

Thank you for the video and thank you for speaking a clear and understandable english and thank you for not playing "music" in the background. As a german guy I´m grateful for that. The gear box looks relatively simple and reminds me on the gear boxes of my motor bikes. However, sitting on my motorbike I try to change the gears as soft as possible. Accelerating, than reducing power . . . an in just the moment, the gear forces relax, changing the gear. After some training it works perfectly without "clutch". When I look at the formular 1 gearbox I can imagine that besides the clever engineering of the system also much shock load will happen when the gears change within some milliseconds. So not only the design but the selection of high tech materials will be needed - I think.
