Why Formula 1 Uses DOUBLE WISHBONE Suspension

In case one breaks

Confirmed, my Miata is basically an F1 car.

Seems like "independent suspension" is not a suspension type in itself, but a category that includes trailing arm, multi-link, double wishbone, and McPherson strut, isn't it?

Isn't "Independent suspension" just umbrella term for almost all of these?
Double wishbone, multilink, MacPherson , trailing arm and many more like swing axle are independent designs

Bro, love your videos but this one needs some serious corrections/additions.

The trailing arm, MacPherson strut, multi-link, and double-wishbone suspension types presented here are all types of independent suspension. "Independent" just means movement at one wheel doesn't directly disturb the other wheel (barring the anti-roll bar). In other words, "independent" just means "not a solid axle".

The "trailing arm" animations don't actually show the trailing arms.

Double-wishbone suspensions are not more complicated than multilink. Very often it's the other way around.

MacPherson struts aren't just ruled out of open wheelers by the lack of mounting points. They're also (mainly?) ruled out by their terrible camber curves, the fact that they put a lot of mass out near the corners of the car, the side forces on the dampers, etc.

Besides aero, another factor in how everything is packaged in a single-seater is to keep mounting points centralized, both to minimize polar moment of inertia and to make it easier to ensure that the structure is stiff around all the mounting points.

Being independent is more of a perk a suspension setup can have. Like Double wishbone is by nature independent, whereas an axle is not.

1:57 - discusses independend suspension. Shows solid axle.

Guys... Your information is off. First, everything outside of solid axle is independent suspension, including formula one. Multi-link is ALWAYS going to be the most adjustable and in theory is the superior suspension. The thing is, formula 1 works a bit different. They can make a new control arm for each race and the mounting allows enough adjustment to suit the packaging.

A multi link system is an "install once and tune as needed" system, vs changing the lengths of parts every time. Great for any vehicle that doesn't require aero. That's why you see a lot of SAE formula cars with that setup. They can also have pull rod or push rod. Basically, you take the wishbones and split the point they connect on the upright. With multi link, you can also have a trailing arm.

Long story short, you've got some decent information, but I think this is overall one of the most incorrect videos y'all have put together.

Scott, you've just sent me into a vortex down a rabbit hole, due to one simple torsion bar...
I couldn't understand how that bar worked, so I searched it, found 2-3 old videos of yours, from your dad's workshop, then continued to some more suspension related videos...
And just got back to report that I've covered over 2 hours of technical reviews and explanations (on x2 speed), to come full circle to your latest vid here!
Great work! Also really enjoy your driving course online!
Keep up the great work! amazing content!

It's a little strange braking down. I'd say we've got two different categories: dependent and independent. Obviously rigid axle is dependent where Macpherson, multi link and double wishbone are independent (you did show footage of double wishbone suspension when started independent section). Where it comes to trailing arms, it depends whether it uses a solid axle or not.

RedBull is actually multilink front for few years.

Double wishbone suspensions were mandatory a couple of years ago - defined by the formula one rulebook until the 2021/22 cars.
Some of the teams actually use multi link layouts (sauber, mercedes and eedbull to name a couple of them).
You have additional degrees of freedom in the kinematics, elastokinmatics and also it might bring one or the other benefit in terms of aero
So no, not all teams use double wishbone suspensions right now...

The script seems like it was ChatGPT as it has glaring mistakes which make no sense. It was said that you want double wishbone suspension rather than independent suspension, McPherson, trailing arm, etc. However double wishbone suspension IS independent suspension. As is the McPhereson strut, multilink, trailing arm, and so on. Independent is the rough classification whilst double wishbone is the specific classification. It's like saying you don't want an animal as a pet you want a dog - a dog IS an animal. I'd assume a human writing the script would have easily picked up on huge issues like that.

RB15 and RB16 used multi link front suspension

Doesn't every bird have 2 wishbones? A single wishbone wouldn't work.

I think you need to mention that independent is not different than all the other types except ridgid, they are sub-types of independent. According to your explanation and video clips shown, independent and double wishbone are the exact same thing, not different types...

Multilink rear suspension gives an advantage over dual wishbones as you can control toe during bump/rebound. So you can have the car gain or lose rear traction during braking or acceleration.

But F1 cars suspension layouts generally have more to do with the control of air flow than suspension.

As Chapman said any suspension system will work in a race car if you just stop it moving. 😂

My car has double wishbone. It makes such a difference in driving through corners, perfect.

I'm not a gear head, but I love the technical videos! Please keep these coming :)

love that Benltey and the sound it makes
