Lego Technic Realistic Pivot Point Steering with Drive / Instructions

[@dgustafsson13]

What a great axle. If I wouldn't have already designed a front wheel driven axle for my VW, I would have used this no doubt. I may use yours for something else in the future though😉 Nicely made video too btw👍🙂

[@allaboutlego1540]

Dgustafsson13 thank you very much!! That's great to hear! 😁👍

[@aiyawocao]

Dgustafsson13 i preferred your design over All About Lego’s. This was because your design was a much more compact one which i was using for a smaller scale build. All About Lego, i still love your design though 😉

[@calumm8466]

Really impressive and a diff won't be too hard to add on somewhere else down the drivetrain! Really good job

[@allaboutlego1540]

Thank you very much!

[@maxradke2189]

Name a more iconic duo than cool videos and crappy music.

[@allaboutlego1540]

max radke well... you can't please everyone😂👍

[@lildunn9704]

This is something not many people would use for steering, I haven't tried it my self but I would like to see this in a future moc, keep up the awesome builds😀😀

[@allaboutlego1540]

Thewheelspin 24 thank you very much! And I am already planning on using it in one of my future MOC's! 😉😀👍

[@lildunn9704]

All About Lego great😀😀can't wait

[@tmoneytechnic]

As usual great quality video! These types of videos are always cool to watch.

[@allaboutlego1540]

TmoneyTechnic thank you!! I am glad you think so!

[@2BitSlow]

Was gonna make a lego/technic car so this will help significantly

[@Plaj3r]

You should increase the speed of jiggling and manipulating with it in your hands that way we can all see everything clearly.

[@wiktorjaworski1710]

0:01 where did you buy this organizer?

[@UAF16]

Well probably in a shop where has organization stuff, im going to buy one too cuz mine sucks Edit: I know im late and ypu might have found something but a litlle help neverbis much😊

[@danielceaespejo4170]

Hello, one question, is it the Ackermann geometry?

[@lc-jrx]

Very good solution! Seems really useful for some later MOCs. Thanks a lot for sharing!

[@allaboutlego1540]

LC-jrx - Lego MOCs, MODs, Ideas and more by jrx thank you very much! No problem

[@legendsofleo]

Nice video! Maybe I could use the axle in a future MOC 🤔☺️

[@allaboutlego1540]

legends ofleo thank you! That would be awesome! 😉👍

[@sawyerklegr]

Cool! Really good design, I have never seen anyone build this type of axle out of lego with drive before :-)

[@allaboutlego1540]

sawyer thanks! Me neither!

[@Просточелна]

A good idea! But there are a lot of backlashes and a very large turning radius! But in general a very good idea!

[@allaboutlego1540]

LEGO Matthew Creations thanks! TBH, I didn't notice too much backlash when it is one the ground (as it shows in the video) and why is a large turning radius a bad thing? :D

[@TheFSXPilot]

What are the pieces connected to the little ball things called? The black ones that look like beams with out the holes in the middle.

[@kihyunltc2735]

So cool! I will use it for my future moc! And this music is great. I heard it from Peter sripol ;) totally, this is amazing!👍👍

[@allaboutlego1540]

Ki hyun's Lego Technic Creations thank you! Yes, I have also heard it from him too 😁👍

[@whoknows2742]

I have just come up with a way to make a virtual pivot steering with drive and suspension😄 it’s mainly based off yours so I’ll credit you when I’m done👍🏻

[@allaboutlego1540]

LEGO Technic Mastermind sound awesome! I am looking forward to seeing it! 😌👍

[@labounti]

Realistic pivot would have slight camber?

[@irushiro2119]

couse the inner wheel needs to turn more not the outer while steering, you have to turn the inputs to the other side. or was the plan to put the mechanics in front of the front axle ?

[@allaboutlego1540]

In the video, it said the inside turns more than the outside?

[@irushiro2119]

well in several spots of this video it looks the other way around to me, ( flimsiness ... fast truning left right ... bad eyes maybe ) and to be honest, i did not see the whole text on the top, couse i´ts inconvenient to look up and down. i based my opinion purely on what i believed i was seeing. the video and your solution are good.👍

[@AngoraWorks]

Nice Build! :D

[@allaboutlego1540]

The Lego Garage thank you!

[@Attika]

Nice job there. It seems to be at the limit what unmodified lego parts can do. One question though: Is the steering is limited by "the most important parts" and not the cv-joint? In other way: Do you see any (even non purist) way to improve the steering lock?

[@allaboutlego1540]

Thanks! And yeah, it is the 'most important part' which I causing the issue. The only way I could fix it (and make the turning radius bigger) is to have the drive train coming out of the top of the unit, rather than the sides - which as you can imagine, would not be ideal unless you were building a truck... 😁👍

[@tomasvotrel5461]

Looks wonderfull! Perfect made. I think it's great for lego mocs, maybe I'll sometimes use it 😉

[@allaboutlego1540]

Samot Lego thank you very much! That's great to hear! 😉😀👍

[@andremarques7907]

awsome work! I think you should try to put independent suspension. But it looks great!

[@allaboutlego1540]

André Marques thank you! That is quite hard to do with this kind of steering, but maybe I will try it at some point in the future!😁👍

[@andremarques7907]

All About Lego i know it is hard but im sure you can do it

[@allaboutlego1540]

André Marques I will try my best!👍

[@implayingrobloxandwht]

Can you tell the me name of the wheel and also the rim pls

[@functionalTechnic]

smart. well done

[@allaboutlego1540]

functional Technic thank you!

[@chesika968]

Nice solutions buddy! But now you should make it suspended :)))

[@Tremodua]

Just suspend the whole unit :)

[@GJBricks]

Smooth! Nice design. Suspension version next 😉

[@kenanfurcle786]

Have you tried to get more angle?

[@ianzalewsky3051]

You should use this on your honda civic type r that your working on

[@초초-l5g]

Is it possible to get more steering angle for offroading?

[@allaboutlego1540]

fourp4nts sadly it's not possible with this setup - mainly because of the gears touching each other🙁😉

[@afoxwithahat7846]

I thought the Inside wheel turning more leads to understeer and wheel lock

[@BlokeOnAMotorbike]

no it improves traction and helps prevent oversteer - which on a front wheel drive or 4WD can wear out the front tyres very quickly. The reason for this is simple: the inside wheel has a smaller turning radius than the outer one since they're both moving around the same focus - the inner one is closer.

[@afoxwithahat7846]

@@BlokeOnAMotorbike but differentials don't solve the issue?

[@berniethejet]

Maybe an Alvin and the Chipmunks song would match better...

[@muhammadamohsin]

Where is the instructions?

[@lFxdedl]

Cool

[@allaboutlego1540]

MafujuxTroll -_- thanks!

[@zionadam6425]

Hmmm I wonder if this is for the ford GT 🤔

[@allaboutlego1540]

Brick by Brick nope... but I have got something in mind which I will use it for

[@zionadam6425]

All About Lego ok can't wait :-)

[@lildunn9704]

Sorry for being late

[@djmiki3029]

dobre

[@91722854]

guys play besiege, u can build anything mechanical, and the under steering is one of the problems I learn about from making such on besiege

[@AadamSoomets]

Show how you build that

[@allaboutlego1540]

Aadam Soomets there is a link to the instructions In the description :D

[@legolost-world5624]

Wow...

[@allaboutlego1540]

LEGO Lost-World thanks

[@justinmw5113]

Unfortunately this isn't how real steering works. So not realistic l. But cool for a Lego build

[@anujmchitale]

Justin Woldridge By realistic, most mean close to realistic pivot points.

[@bugajek1111]

Not really realistic. Have You heard about Ackermann steering geometry?

[@chrismolenr]

Sariel Said this was imposeble

[@TheFSXPilot]

First!

[@derrickstorm6976]

Actually it's not realistic :/ Nice still :)

[@allaboutlego1540]

Jussi Raitoniemi thanks, oh, and just wondering, why? 😉👍

[@chriswright6068]

For one, if you look at an actual steering system on a car, it pivots around the knuckle, not the wheel. For another, steering systems have the inside wheel turn more than the outside wheel as the inside wheel has to make a tighter circle

[@chriswright6068]

Cool design,but not how real cars do it

[@allaboutlego1540]

Chris Wright thanks, yes, you are right, in a real car the wheel does pivot from the steering knuckle, although the wheel is usually placed over the knuckle (in other words, the knuckle is 'inside' the wheel) so the actual pivot point is close to the centre of the wheel. (That is what I have being trying to replicate here). Also, I did mention in the video that the inside wheel turns more than the outside one. 😁

[@Klikkitse]

Jussi The pivot point is realistic. The play in the system set aside looks like the scrub radius is almost zero, which means the pivot point, albeit virtual, is in the correct place. @Chris Wright @2:14 it says that the steering has Ackermann geometry. You can also see from the attachment points of the steering linkage that it has to have some degree of the correct geometry. You didn't watch the video, did you? The main reason why you would design a virtual pivot point like this with Lego is because 90% of Lego wheels don't have enough space inside to put the steering hardware where it belongs. Especially the smaller wheels (inch or smaller), where the axle hole may even protrude from the wheel, making the scrub radius enormous. And by enormous I mean the wheel well starts taking up space from other stuff and starts looking stupid.
