In this video, I open up an F1 gearbox to find out what's inside and explain a little about how it works.
I used to work on race cars many years ago, but it's been a while since I worked on any part of any car, let alone a Formula One car gearbox - as you can probably see in this video.
Anyway, it was a lot of fun to take this apart and see what's inside.
Thanks to Mansell Motorsport for allowing me to take this apart (and for them to put it back together!)

The violent impact each gear shift produces when gears are engaged on such small pieces of metal at such high RPM is unfathomable! Thanks for the vid, it makes me truly appreciate the sophistication of F1 engineering.

@MrWarhead16 Жыл бұрын

My thoughts too. I thought they have synchronizers attached on these

@bertram-raven 9 ай бұрын

@@MrWarhead16 As you increase the number of dog "teeth" you require less in the way of synchronisation; as this is also a sequential gearbox, the need for synchronisation is reduced. Another method is the piston which moves the gear selection shaft (which in turn moves the drive dogs) has electronics to synchronise the shifting of the dog at just the right time. "Consumer grade" manual H-pattern gearboxes usually have just three drive dogs, hence the need for synchromesh systems and rev matching. Modern sequential gearboxes now engage both the current with the next gear pre-selected. Manual pre-selector gearboxes used to be a thing on old Volvo's (change gear, then push in the clutch, release the clutch, and "bingo" the gear is selected. Fun fact. At Monaco, a Red-Bull engineer was looking at the Super Aguri car when his eyebrows went up and he asked "How in the hell have you got our gearbox?!" (At the time, Red Bull was one of the few teams with seamless shift and the SA gearbox was identical!) Aguri san was not phased at all. He replies "Actually, you have ours." This was technically true. The gearbox run by SA was the first seamless gearbox on the grid when it was originally in an Orange Arrows. SA bought the entire OA equipment and intellectual property. However, the gearbox was also licensed by Red Bull (well the original team did) when OA folded. I loved the access I had in those years.

This example is really a good one because it's actually cleaner and more simple than a gearbox from a road car : no reverse, just two shafts and two sets of gears, the shifting mecanism is also beautiful by its simplicity (vs the complex forks on a H pattern shifter). I just wonder how it manages to shift smoothly, even if it's not the main concern for a F1 it's still important for reliability and predictability, but I guess it works perfectly !

Brings back memories, I worked on the gearbox and traction control unit for the 193 and 194. Shift times were 10 to 25ms as I recall, coordinated with a momentary ignition cut using the same interface to the engine management as the traction control. It would automatically retry shifts if the dogs hit face-to-face as happened occasionally and inhibit shifts that would over-rev the engine. TC and over-rev protection banned in '94, the FIA came in to audit our software. Happy days but extremely hard work!

I believe that what you call a layshaft is, in fact, the input shaft. A layshaft is defined as: A layshaft is an intermediate shaft within a gearbox that carries gears but does not transfer the primary drive of the gearbox either in or out of the gearbox. A layshaft in a car is used almost the same, but the input and output shafts are in line. The power is transferred with an extra gearwheel from the input shaft to the layshaft. The principle of this gearbox is very much like a motorcycle gearbox: straight gears and dogs. Motorcycles also have a separate input and output shaft, but on most the moving parts are on both shaft. But a really nice video!

@immikeurnot 5 жыл бұрын

Yep, that's the input shaft. A layshaft is also called a counter-shaft in some manuals. Straight spur gears like that are louder but stronger than helical gears, which is why one is used in motorcycles and race cars and the other is used in passenger cars.

It's actually interesting to consider that on a mechanical complexity level this F1 gearbox is very simple and is more comparable to a car gearbox from the 50s.

Some good info' in the video - and a lot of 'less good' in the comments. You may have noticed a shaft coming out the back of the gearbox, near the bottom - that is a starter shaft - an external strater is engaded there to start the engine. The input shaft isn't connected 'directly' to the engine, but via a clutch assembly about the size of a large man's fist - worth a separate story just on the clutches, perhaps? most performance and race gearboxes are gas operated, but the speed demands of F1 means that is too slow and hydraulics are used. That isn't a layshaft, it is an input shaft. Some of you who have some experience in race gearboxes may have noticed that the input gears are machined as part of the shaft, rather than splined on - this is because F1 gear ratios are fixed (one change allowed mid year, if that still applies) and it is stronger and lighter to build them that way.

@taratownsley668 5 жыл бұрын

I’ve worked on many formula car gearboxes in my previous employment. The reason the gears are “paired” as you say on the shaft is because the shafts are only supported by bearings on the ends so you want your highest loaded gears closest to the ends of the shafts where there is support. 1st and 2nd gears are next to each other on one end of the shaft and then you switch to the other end of the shaft for 3rd and 4th. As you shift gears higher there is less torque produced so there is less spreading force between the gears. If you placed 1st gear right in the middle of the shaft the spreading forces because of the amount of torque involved will flex/bend the shafts. By putting the higher loaded gears at the ends of the shafts you are putting them where the shafts have the most support from the bearings. That is the only reason the gears skip around on the shaft. The groove in the barrel that moves the shift forks through the shift pins is machined to operate in this order.

They have neutral and a crew to service the car, that crew can push the car backwards. Reverse is a waste of space and materials in a vehicle that is built to only go one direction 99.99% of its life.

@@oldleatherhandsfriends4053 Thats not the case anymore. Todays F1 cars do have a reverse gear and you better use it because If you need someone elses push to get out of a deadlock, your race is over.

@@Chuckiele interestingly, modern F1 cars shouldn't necessarily need a reverse gear, they could pull the clutch and reverse the polarity of the electric motor. Of course that would only be the case if the motor is after the clutch, which, after reading the technical regulations, turns out to be illegal. I tell you, the engine regs fucking suck, they leave almost 0 room for imagination. And it's not like they do it to keep "road relevance", variable geometry turbos, twin scroll turbos, VVT and VVL are all very common among modern roadcars, yet they are forbidden by the FIA. The regs are so tight that they might as well make the entire PU a standard component, I could write a massive paragraph explaining why having such tight regulations is stupid but it's late and I'm tired, maybe tomorrow. Here are said regs btw, I'm linking the 2022 ones because the PU will remain mostly unchanged and they show were the future is headed www.fia.com/regulation/category/110
