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

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.

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.

@@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.

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.

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 ?

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.

F1 gearbox is simpler than the 4-speed manual one on the Pinto that I took apart to fix during high school. They got rid of the synchomashs as F1 mechanics can't wrap their head around how they work.

That was a great vid. I didn't expect the pitch of the gears to be that coarse in F1. Also you can definitely tell how 3d printing is revolutionizing machines, casting that housing, or machining it from a billet would be incredibly difficult by comparison.

Love it! It is way more simple than thought

I almost didn't watch this but I LOVED it! Thanks man, only the most intelligent & knowledgeable can learn and teach simultaneously. Big ups

I love the level of detail you go to in your videos. Keep it up!

This is somewhat different than the gearbox on the Tyrrell 022 that I worked on. The cases were made of magnesium and there was only one selector barrel.

I'm so glad you mentioned indeterminate design, his videos where he makes an aerodynamic beast of a remote controlled car are brilliant

And in the first lap out of the pit's you need to program these two rotating bars. That's why Max had to go to all the gears in Hungary on a wet track and made a mistake going to the grid. Thus making everything going in sync. So, it's pretty precise how they to that. Precise enough to change overnight or temprature cycle.

Never knew F1 gearboxes were this full of tech and precision. This video was incredibly informative and well put together. The seamless shift technology seems like a game-changer in the sport.

What can be salvaged, and how often do teams truly build a new car from the ground up and not rely on reclaimed parts? Thanks❣️

Great video Scott!

Anybody who has stripped and rebuilt an old motorcycle gearbox (e.g. the AMC/Norton box from my 1966 Norton 650SS) would recognise much of that box, selector cam (although on the AMC it's a slotted plate) with multiplate clutch, but without dog rings (they're directly on the gears), reverse, and the dual selector cam.

At first I was a bit surprised that F1 cars still have an actual reverse gear. After all, why not just use the hybrid system for that, and reverse on electric power alone. But then I realized where the MGU-K is placed in the whole power unit......yeah, that's not gonna work... But impressive piece of angineering, and very cool to see!

brilliant video. thanks for the insight.

Just like a bike gearbox, where it's called a positive stop mechanism and has been in use since the 1930's in basically the same form. A bike gearbox, well, a modern type anyway, can be shifted without using the clutch, by slightly rolling off the throttle. Although there are now quick shifts where the ignition is momentarily killed by the ecu to allow almost instant shifts. I remember discovering that F1 used the same system as bikes in the late 80's and wondering whether it was influenced by a biker F1 designer! That double selector system is very ingenious though! Most impressive thing for me here is the 3d printed Ti gearcase, wow!

This is awesome, thank you!

Love this video. More of these please!

As software developper, I'm always fascinated to see mechanical parts working. I'm used to see things working moved 'only' by logic.

Thanks for the excellent video! It is difficult to picture how a titanium 3D printed part works. Awesome tech!

Good, well explained video ,Thanks.

This video was great, thanks! Also the 1924 Type 35 Bugatti used the engine as stressed member :)

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. East to see how just a brush of a barrier in practice makes the mechanics see stars knowing how big a job it is if that housing is cracked.

This is good content Scott. keep them coming.

The dual barrel setup is ingenious, and it's basically a more hardcore version of a DCT in a car, just with two selector barrels instead of two clutches. Makes me think if it's ever going to be implemented on a high-performance motorcycle with a mechanical linkage instead of a hydraulic valve.

what an amazing idea for a business, kudos to TDF

F1 tech is always so alien. Very cool video

It's amazing that the dogs can transmit all that power, being as small as they are. Unless I got it wrong - they are a very high stress part in the system.

Awesome! Please sir, more 🤘

Motorcycle was the first thing that came to mind.

Pretty much looks like a motorcycle gearbox very cool. Long live the dog box 📦 ❤

That is SO cool!! One thing I've wondered about is ... does the driver, or a computer, decrease the throttle during a shift to avoid breaking the tires loose?

Fantastic video.

They also put ref and sync sensors on the shafts (same sensors used for engine cam shaft timing for fuel and ignition) to know when the dogs won’t line up for the next gear to be able to seamless shift with a single clutch. That’s why when you hear the engineers say “we have lost gear box ref or gear box sync” they can still shift but not as quickly and also not advised to shift until it comes back online if at all as it can result in box damage if you bash dogs.

Can you also do a vid on the F1 electronics and engine mapping ? Thus what are the boxes from the FIA and what are there own. And what is all allowed from the electronics side. Like what can you do on track and what in the pits or driving through the pits.

I know a man who machines selector forks for F1 gearboxes, their gearbox was used for years successfully. They then put a camera in the gearbox and he said the shafts and forks were visibly bending😮.

Its old style F1 & LMP1 gearbox. From about 2013-2014 F1 and LMP1 use cassette type gearbox, where there are the stressed casing from CF and unstressed gearbox inside. More efficient because you can change the suspension arm points without changing the whole gearbox case
