The animations are amazing and a great video in general. Keep em coming
One thing that should be mentioned:
Under Breaking and acceleration the car front and back tend to move.
With negative a (breaking), the back of the car will tend to move up, while the nose tends to move down. In the past Push Rods were used at the front, because they allowed this behaviour more then Pull Rods, and everybody loves a lower nose. Pull Rods on the other hand tend to allow an upwoards movement more, which was wanted at the back to get even more rake and thus the nose even lower.
The ground effect cars dont like this behaviour, rising back and diving nose can seriously compromise the ground effect generating aero. Red Bulls config keeps them stable under breaking, allowing Max Verstappen to not only trust his car, doing his corner rotations with more confidence and trust at the end of the brake phase.
Note that one factor that makes the nose of the RB not go low is the "anti-dive" suspension designed by Newey. Which he basically changed the mounting points of the upper wish bone, placing them at different heights and use the torsion created by these to control how much the nose moves. Then the suspension does the rest.
@@The_Curious_Cat Important note is that all cars have some "anti-dive" (and also many other "antis", including "anti-lift" of the front and "anti-squat"on the rear on acceleration, etc.) AND this isn't designed by 1 person only, there is a whole engineering team behind all these decisions, probably hundreds of engineers.
The biggest importance on a ground effects aero car is in maintaining the relationship of the floor to the ground as close, consistent and stable as is possible. An example of this is where Hamilton secured 2nd place but was then disqualified because his floor ran too close to the ground upon inspection of the wear on the metal wear blocks. .... "But it worked so much better!" Even 1mm (40 thousandths) can make a HUGE difference
So, it comes down to driver choice as well.
What a breakthrough concept!!! This will bring about world peace!!!
Really cool video! The animations were great and it was put together concisely, so not to unnecessarily drag it out.
I'm loving the new content. Many would have given up when the radio videos started to get blocked but the way you've steered the channel to what it is now is incredible!
By far, the best illustration of F1 suspension set up! Thanks
Clear. Precise and to the point. Great animations and graphics. Easy to understand. Great work!
I like that both major f1 adjacent channels are moving into more details videos with greater animation and narration. Great work and awesome for us fans!
Thank you for a succinct & easily consumable concept no one has been able to demonstrate to me prior.
Super clear! Looking forward to more of these. Awesome job
Finally! Never understood what the difference was and what they actually do. Thanks to that I understand it much better!
Top notch animation and explanation. Please keep these coming, they're extremely helpfull to the community.
Perfection. Couldn't have been presented better!
Thank you this is the information I have been looking for so glad I subscribed to your channel.😊
Great video, and awesome explanation! Very well done!
A picture or in this case a video is worth a thousand words. A dry subject made easy to understand.
Great video! Beautiful animation and presentation
Amazing video. Top notch quality
thank you for really nice animation keep up the good work.
Very well put together n explained thank u
Excellent animation and explanation. IIRC, Gordon Murray introduced the first pull rod suspension on the front end of his BT-44 design for Brabham. Though in that car's case the front shocks were partly exposed, it wasnt an aerodynamic issue due to the front bodywork aerodynamics. It also allowed them to adjust the linkage and rockers to create one of the first rising-rate suspensions. At least one designer experimented with a mixed front end where one side had a pull rod and the other a push rod...might have been an oval specific car (late 80s early 90s...AAR, Coyote, Chaparral??).
This is so relaxing, not only did it educate me but also helped me get to sleep
Outstanding video! Can you make something about the anti squat and anti dive suspensions?
Great video and a great demonstration of both designs - thank you! Just one thing, the tethers are designed to prevent the wheels from falling off, not the tyres. My OCD is back in check. 😊
AMAZING ANIMATIONS
awesome job dude
Great quality video 👍
The animation is crazy good. If your team draw from scratch, it is a mighty effort altogether. I highly doubt the Redbull gave the drawing.
This is great.. more Tech stuff please
Whats impressive is the complete different suspension set ups that the new car will need. Darring, but also shows the rescoirces that Redbull has at thejr disposal in order to over come the obstacle.
that was great, thank you
That is possibly the best technical video I have ever seen on so many levels. Thank you. If you ever cover motorcycle suspension set up, I will be there. Sub 🙏🏻🙏🏻🙏🏻
Sooooooooooooooooo, THAT'S how it works...! Thanks, that was very helpful!
Extreme High Quality Video.
Wow. So good. Thank you. 😊
Animations are next level
please do more of these i just subscribed
really nice information
The VO is perfect for a paranormal investigation channel.
👏🏾👏🏾👏🏾👏🏾 good vid
Fantastic video! Could you explain the anti-dive and anti-squat suspensions geometry.?
Amazing video, love the animations with proper and clear narration! Keep up the good work!!
One suggestion, you can work on the timing and pauses in your narration. Between sections, it felt like (as a viewer) there wasn't enough pause for us to register the previous section.
I think we will see more pull rods at the front this year as teams really want to grab just a smidge of better anti-dive capabilities. Mercedes tried to retrofit an RB appropach last year without building a new chassis which also meant that the front pushrod stayed for the season.
Anti dive comes from the angle of the lower and upper control arms relative to the horizontal, not the suspension rod type.
Great video and explanation. I would like to know how the electric motor and the combustion engine work together. Where in the drive train does the electric motor go? E.g. Does it connect to the drive shaft or flywheel or neither?
My guess is that Visa will run the RB suspension config this season and a few other teams will also run the Pull / Push suspension setup.
Nice
Can you make a video on anti-squad and anti-dive in the suspension of F1 cars?
Can you make an animation to show how the air move under the car? I’m really curious about how it works, does it move like a vortex or straight.
bruh this is animation what ive benn searching for quite a time.i would like to see more detailed animation of explaining stuff about f1 cars like this😅, but also i have been wondering for how exactly mechanism looks like are used in f1 cars steering that able to achieve anti-ackerman steering geometry. and for more: what the mechanism in mclaren speedtail's front wheel cover
cool! Can you explain other parts of the machine too?
Rel Ball nice ✅
F1 off season I Un sub from everything that has to do with F1 ( even on twitter ), it’s annoying & so unnecessary. But we’re gearing back up again, you’ve gained a follower my friend.
Nice video, short sweet & it gets to the point.
Cool

Where are you getting these incredible 3d models
Like !
What happened to the team radios after every race? :(
Im gussing teams have tried both or did they have to choose ?
Will there be any pull/pull configuration?
What would be the disadvantage for pull-pull config?😬😬
Another advantage of pull-rod suspensions is that because the pull-rod is acting in tension, the cross section of the pull-rod could be much smaller, and rigidity is less important (in theory a flexible cable would work just fine).
With a push-rod suspension, the member is working in compression and must be bigger and beefier to prevent it from buckling or collapsing under load. Compared to a pull-rod, the push-rod by necessity is both bigger (less aerodynamic) and heavier than a pull-rod. Both qualities anathema to modern F1 car design.
They both have to work in tension and compression. Wheels move both up and down on cars. Just pull rods typically experience more tension than compression and vice versa for push. A pull rod couldn't be a cable as it would go loose after bumps and then snap in tension. You would get a peak load in that scenario
Is redbull using front pull and rear push to make the car tip front-ward? This can increase oversteer hence suit Max's driving style
The suspension is so stiff with both push and pull rods that it is more of an aero choice than anything.
What about twist rod suspension?
Script sounds like ChatGPT
Would you like to talk about vortices?
you sound like the guy from disaster breakdown
Its weird yet cool to see Redbull and Alpha not sharing their car setups. They could've just copy pasta
Will Be interesting to see if Visa switches to Pull / Push this season.

What is restricting teams using Front Pull Rod and Rear Pull Rod?
The locations where the rods connect to the car. At the back you have the gearbox, floor and diffuser so its harder to have a pull rod, but looks more streamline if you can fit it down lower. As mentioned in the video, pull rod at the front means the components are under they front if they need to make adjustments or swap parts it's a little more difficult. Its mostly an aero choice of where you want those rods as they cover them with carbon fibre winglets to direct the airflow as desired
Pulls of names or 7 taught by G forces
i wonder why no one uses F: Pull R: Pull, yet double Push has been.
I only know push/pull/legs configuration
I could be wrong but I was sure that F1 cars use heave springs and not coils?
They have several springs in all forms. The wishbones are not on bearings (rod ends or spherical bearings normally in other Motorsport) they use solid titanium flex joints to bond the wishbone to the chassis tub (adds a spring rate in all modes), torsion bars for the base springs (has an advance over coil spring as it’s a double acting spring, better for control), heave springs for pitch control (either as a coil or belvil washer spring), and torsion tube again in the roll bar spring (mainly for roll rate control), in the form of a T bar or U bar depending on the layout but I think they mostly run U bars at the front now for roll. I may be wrong I haven’t been in an F1 garage yet or seen any recent photos from this years cars.
@@apt962 Yes, I think he used a compression shock absorber for simplicity's sake. He would then have to explain all of the different facets of the suspension beyond push vs pull rod otherwise.
F1 suspension uses torsion bars, not springs
I still don't understand how it actually translates on the road. Where would it make a difference between the two, when it comes to real life racing?
the kind of people who can explain the on track differences are working for F1 teams and not youtube channels, haha
Its mainly aero and packaging the components with the other parts of the car such as the front wing to suspension arms to the side pods and floor and air flow to the back of the car passing over the rear suspension to all work together
Animation last part not accurate, the tyre spinning in real life are more stable, tyre in f1 is super stable
That explains why McLaren is nearly as good as Mercedes
Or in other words: the difference between winning and losing 😂
Im not a engineer but the way you show how pullrods are working is false.
There is no force really "pulling" on the dampers its ether mostly also pushing on the dampers but with a revised rocker alignment
When wheels move up relative to the car one arrangement pushes and the other pulls. It's literally why the call them push rods or pull rods
They animation isn't of an actual F1 car. They use different torsion rod springs and the dampers are now also mechanical springs instead of air or hydraulic dampers they used in the past. If he used those then it would be difficult to explain in the simplest of terms. What we see as far as the effects between the push and pull rod assemblies is correct even if the spring damper assembly is not what is used.
Couldn't have made a poor quality video. Nothing is clear or understandable
Maybe proofread yourself? You mean he couldn't have made a poorer quality video? I understood the video a lot more than your comment
