The Formula 1 Car with INFINITE GEARS

The Formula 1 Car with INFINITE GEARS | The Blueprint

2 роки тому

This 1993 Williams has one of the most unusual gearboxes ever in F1. Rather than 8 gears like modern F1 cars, it had an ingenious mechanism that could smoothly change through an infinite number of gear ratios.
It promised to make the car easier to drive, more efficient and much, much faster.
It's called a Continuously Variable Transmission, a CVT. It’s not a new thing but was new to something as powerful as a 90s F1 car.
It meant the car was always in the right gear and could make the best use of the engine's power, delivering all 850 horsepower, all the time.

So how do they work?
There are many different types of CVT - with more clever ones being trialled in cars all the time. They’re not new though and are often used on anything from a Pillar Drill to a Scooter.
But this is the one that was used in the Williams car, it’s essentially two pulleys, with a belt connecting them. One pulley is connected to the engine, the other to the wheels.
Each pulley has one side fixed in place, whilst the other side can move.
When the pulley is squeezed together, it forces the belt up the cone, the same as shifting to the largest cog on the back of your bike.
The same happens in reverse, pull the two sides apart and the belt moves to the bottom, similar to the smallest cog on a bike.
If you were to hold the pulley somewhere in the middle, you can have any gear ratio you like, as the belt can deliver power anywhere on the surface of the pulleys.

One of the weird things is that in cars sold today, they usually make the CVT behave like a regular automatic, mimicking gear shifts, because people didn't like it. The CVT I drive now is definitely the smoothest ride I've ever had, and works great, and you don't "feel" the transmission shifting like it would in an automatic, but it still mimicks the behavior. I drive a 2017 Civic. It also wants the transmission fluid changed every 30k miles, but only half the fluid gets swapped each time with how it's setup.

While the high revs of a formula 1 car is its own challenge, so is 40 tonnes of box bouncing on terrain that's impossible to drive over with wheeled vehicles. The mostly guaranteed reliability distance of a modern tank is closer to the full formula 1 race season than a single GP.

@emi2047 2 роки тому

Well explained, but I think there is a little misconception at 5:50. If you want to maximize acceleration, you want to maximize the wheel torque. In order to achieve that, the engine must be at its maximum power regime, not at its maximum torque regime. The reason is that power =torque*rotational speed. This equation can be applied to the engine, but also to the wheel. So, for a given wheel speed, the more power, the more torque at the wheel, and this is achieved with the engine at the maximum power regime and a shorter gear, instead of the engine at the maximum torque regime and a longer gear.

@progDes 2 роки тому

Exactly. I was surprised to see this inaccuracy in such a well informed video

@emi2047 2 роки тому

@Andrew H at maximum torque. The torque at the wheel is proportional to the engine torque at a given gear ratio. So the maximum force at any gear will be at the maximum torque. However, if you can switch gears, at a given speed, you will get more force at the wheel if the engine is at its maximum power regime, using a shorter gear, than using a longer gear with the engine at its maximum torque regime.

@emi2047 2 роки тому

@Andrew H I don't understand your question. Power (i.e. HP) has a physical meaning: is the amount of work per unit of time. You can calculate that as force*velocity, or as torque*angular rate. An ideal gearbox with no energy loss at all, would keep the input power equal to the output power. So the power provided by the engine would be the same that the power at the wheels. In that scenario, you could have different torque levels at the wheel at different speeds, but the product wheel torque * wheel angular rate will be always equal to the product engine torque * engine angular rate. So, what actually moves a car is the torque at the wheels. But how much torque you can have at the wheels at a given speed, is limited by the power available. Does this make sense to you?

@emi2047 2 роки тому

@Andrew H Yes, I think it is becoming a little existential. But I think you are not completely right. For example, measuring a torque is no easy. It is usually measured indirectly. For instance, you can measure the deformation of a material with known properties (using strain gages, for instance), and deduce the torque from it. Looking at the question from another point of view, the fundamental physical magnitudes related to torque are time, mass, and distance. A torque is force*distance. But force=mass*acceleration. Moreover, acceleration =distance/time². So, if we want to express the torque as a decomposition of the fundamental physical units, torque = mass*distance ²/time². If we do the same for power, which is force*velocity, and velocity is distance/time, then the power = mass*distance ³/time³. I am typing this on the phone, I hope I am not making any mistake with the math. My point is that both are derivated magnitudes, which can be expressed as a combination of three fundamental magnitudes, but this does not imply that they have an useful meaning. For instance, you can use the power to predict the maximum speed of a vehicle, but you will need the torque to calculate the resistance of the gears of the gearbox.

@progDes 2 роки тому

Emi explained it well from perspective of the gearbox. I would suggest to look at it from the different angle. Here is the equation for kinetic energy of moving object: E = 1/2*m*v^2 From this you can quickly derive: V = sqrt(2 * E / m) V = sqrt(2 * Power * t / m) Which clearly shows that it's the Power of the engine that is a key factor to acceleration.

@Brinta3 8 днів тому

Yes, the FIA holds back some advances. This is no secret. Main reasons: 1. Safety. You don’t want cars going through the corners at 400 kmph. 2. To keep the cost down. If certain teams that are rich or have huge companies behind them get to spend endless amounts of millions, then it just isn’t attractive anymore for small teams to stay in F1. According to Wikipedia: “CVTs were prohibited from Formula One in 1994 (along with several other electronic systems and driving aids) due to concerns over escalating research and development costs and maintaining a specific level of driver involvement with the vehicles.” 3. The individual skills of the driver must remain important. As mentioned in the quote above, you don’t want the cars to do all the work for the drivers. The first CVT was invented in 1879 and is still used in cars, e-bikes, tractors, and other vehicles. You needn’t worry about its development.

@mrsiersciu 2 роки тому

I don't to think you're right about picking the top torque of the engine for best acceleration - you always want to maximize engine power. Here is why: at any given speed you want to maximize the torque at the wheels, which means that you want to maximize the engine torque multiplied by the gearing ratio. When you do the maths, you'll see that this is essentially engine power divided by rpm at the wheels, so if you want this number to be maximal you need to pick such a gearing that the engine is at its power peak, not torque. To put it differently, if you make your gear longer so that you can have peak torque in the engine (instead of peak power), the extra torque will be consumed by less aggressive gearing, yielding lower torque at the wheels.

CVTs would also gain a traction advantage since the car is much less likely to be upset by gear changes (brief spikes in wheel force) since it all happens continuously. This would make the car easier to control on throttle in corners and push harder because you are not limited to a single gear. This would be especially true following corners with changing radii. Driving in rain would also be easier since drivers have better fine control over managing wheel force with a CVT. The smoothness of power delivery is pretty important to maintaining control and a CVT really makes that easier to accomplish. So yes, I believe it was banned mainly because had it been done reliably back then, it would've had a huge advantage over geared cars.

1 issue - The maximum torque point around 6:00. HP is a torque rate and the reason you go faster and accelerate faster is due to torque....because it increases the HP. So the sweet spot for the CVT is still the HP peak of the engine, no matter whether it's a slow corner or a high-speed straight

5:50 I think You might be wrong here. For max acceleration the engine will always need to be at highest power, not highest torque rpms. Gearbox will always provide the max torque at the wheels when the engine works at highest power revs. Gearbox ratio (high reduction) will take care of this.

The Williams F1 car in question is on display at the DAF museum in Eindhoven (NL). For anybody interested in cars and trucks a great museum to visit by the way. Also the famous Turbo-Twin Dakar racing trucks are there. The CVT steel belts are actually still being made in Tilburg at Bosch Transmission Technologies, previously known as Van Doorne Transmissions.

The vid posted years ago showing the design of the hd gear driven cvt seems to have been scrubed from u tube. The origanal designer is an electronic engineer, and the design was acquiesced by the military for drive systems, and to maintain rpm for alternators. Ive yet to have a chance to look inside john deere tractors, but i assume they have been given righs for their drive systems seeing as they are superior to hydraulic systems.

@JessSimpson1313 Рік тому

CVT + Blown Defuser would have been world beater. Having the engine just always redlining while the acceleration peddle only adjusting the CVT so that the blown Defuser was always hot but the car was only accelerating via increasing the CVT ratio.

Seeing things like this make me wish that there was a "open time trial" event during the week-end where each constructor were allowed to send in cars with new technology to get the best lap time. Current FIA rules makes it quite complex to try to innovate, and there would be so much more interesting technology coming from F1 if there was room to experiment.

7:40 It was Dutch, DAF which usually makes lorries. They had a small lineup of cars though and their cars also used a variometic gearbox which makes them fairly unique compared to other cars. One feature of the variometic also is that you have a gear for reverse which means the car can go almost as fast backwards as it can go forwards which is what the DAF 600 became famous for.

The last image in this video is from a Williams (showcar?) in the DAF museum in Eindhoven (note all trucks in the background), not the Williams museum in the UK. I imagine Williams have the original car in their museum. DAF was the Dutch company assisting Williams with the development of the F1 CVT. The DAF museum does have an original Williams Van Doorne CVT-unit on display. DAF developed the first ever CVT, calling it Variomatic, for their first passenger car. All successive DAF passenger car models used it.

They could do system where the car is always at max throttle, and the pedal varies the rpm in order to mediate power. Below idling rpm, the throttle would be lowered as normal. That would save the engines lifespan (which by extension increases the power teams could put through it), it would maintain an optimal rpm and power level at all times for the driver’s exact needs, and it would quiet the engine down more for the audience.

A drawback of that could be the braking, without downshift it's a different thing. When I test (I'm a tire test driver) with cvt cars (Toyota f.e.) I always have a "weird" feeling, especially in hard brake, if the car is not stable during braking. Sometimes, especially with rwd cars, downshift is essential. But I test on road car, they are not built to be pushed on the limit on track, so maybe that's why.

@RDMracer 2 роки тому

That may just be because it's a Toyota. My RWD Volvo 340 does have hard engine braking when fully off throttle, but I recon it makes things easier, especially in a situation without ABS.

@GiorgioLupi 2 роки тому

@@RDMracer I have a 2017 V60 cross country automatic, and when I do emergency braking on road it actually downshift quite hard(more than the e92 I had before even when in sport mode) so I think it's a Volvo feature support hard braking with some gearbox setting

@GiorgioLupi 2 роки тому

@@RDMracer also as an insider in automotive r&d I know that Volvo develop cars for Sweden without adapting to the rest of the world. Considering how slippery are the road there (due to snow,ice etc) I can easily understand why they develop the gearbox in this way

@Wouldpkr 2 роки тому

it all depends on how its setup to operate really. My Honda Hobbit (Camino in the UK)"downshifts" with the starter clutches installed, remove them and make it a pull start or push start with a one way bearing and you lose the downshift. Funny that the system above was designed in Belgium as the Camino is kind of popular there still to this day.

@mikewheeler9011 2 роки тому

The great thing about CVT is you can program it how you like. When the driver is on the throttle, you can have the engine in peak power, and then on braking you can program 'Down shifts' into the CVT that the driver can control like a conventional gearbox. I think this is the best of both worlds. With development they could be strong and fast enough for F1

@Sleepydwagonman 2 роки тому

I'd be curious to see what Toyota/Lexus's eCVT hybrid system could do in a race car. The batteries are an additional weight but the 2 motor generators that make up that eCVT replace both alternator and starter motors, so it's not actually that much weight especially considering that they are the gearbox. The cooling and air con systems are powered electronically as well, so you don't have that loading coming off the crankshaft and sapping top speed. That said, they're tuned to get the vehicle to a cruise speed and then they'll up the gear ratio so that the engine goes to not far above idle, so the steady state of the engine is a low rpm and the opposite of the F1 CVT steady state. There's a curious motor lag though when using kickdown as the engine speeds up after you floor it (mostly goes away in the sport mode).

I knew Peter Weismann in Costa Mesa Ca a Smart Man but if you had a Weismann gearbox good luck in getting a replacement part that was to the same Dimension as the original parts. That way the boxes never caught on. March used Weismann boxes in the Indy car one year and switch the next year.
