FRONT AXLE with Disk Brakes- LEGO Technic (MOC)
Вставка
- Опубліковано 31 бер 2018
- Hi guys, this is my idea for pretty advanced front axle. Except authentic steering geometry and others bits and bobs, the most interesting function is brake system.
Rear axle can be easy built, using the same system with small changes to make it even more robust.
I also invented custem hubs for Porsche's wheels. The biggest advantage of them is that, they are smaller than official ones.
This enabled me to design this axle with steering pivot, relatively close to authentic one.
I hope you like it and find this concept helpful in your MOCs.

this moc is more advanced than my actual cars suspension
Sean Whatstone then be a mechanic
Spiderman - What about a multilink suspension? (Source: en.m.wikipedia.org/wiki/Multi-link_suspension)
@ ChronoGXay
He said simple and practical. A multi link is actually more complex than a double wishbone.
It was interesting that back in the 80s and 90s.. magazines like Car and Driver and Consumer Reports hounded the US domestic auto manufacturers for having “medieval” MacPherson struts while most Japanese imports used double wishbone suspension.
The truth was the Japanese car makers like Honda wanted to use MacPherson struts but it would make the engine bays on their cars like the Civic and Prelude too small. So they used double wishbone suspension and sold their cars on superior handling.
Then quietly in the early 2000s they installed MacPherson struts on their now larger cars and everyone except die hard fan boys didn’t care.
Looking at the parts used here and how it relates to real car suspension it's basically the same thing but just looks advanced because its smaller and has more components for strengthening the plastic rather than just using metal that's already stronger with less support
Oof
Because you have the brake system, I’d recommend using a security gear to connect the motor to the driveshaft
You mean the white clutch gear?
@@MoonIyght yes
How long until someone combines all the moc’s for the functioning engine, suspension, and makes a full custom car? That functions and drives?
2nd year of mechanical engineering here 🖐️😃
They have actually made a Bugatti Chiron out of technic that drives. I’m not sure what it was powered by though.
It was driven by a lot of pf L-motors, but it had steel frame, so definitely not 100% lego
Exttero's Lego Technic Creations yeah I didn’t think it was totally made of Lego. It was still quite a cool build though.
MushyMonkey 20 with a top speed of 12 mph lol, still very impressive and intriguing
I will never be unimpressed. This work is so amazing, it is a masterpiece. It's the Mona Lisa of LEGO Technic, and you are the Leonardo Da Vinci who made it. I can't tell you enough how amazing this is.
I am amazed you were able to add caster angle with Lego. I have never seen that in a lego moc before.
I've seen caster angle in MOC before but not this nicely done. The previous version I saw had whole front suspension angled as a big module.
Maybe you will find newer version even more interesting 😊

Wow! So many working mechanisms! Magnificent!
This is an axle that can be modified to not use the brakes, which is extremely beneficial for me, as I have looked for an AWD, suspension, and steering axle. The only result I got was not what I wanted, this is much, much simpler.
So I hope that my idea will be helpful
YES, THE MOST HELPFUL!!! : D
Nice design!
This Thing literally got everything a Front-Axle could have. Nice Design.
and my new version has even more ua-cam.com/video/TyOA9fpBFQs/v-deo.html
Great design! Love the use of pneumatics for the brakes. And probably the best Lego implementation of disc brakes I have seen yet.
I think it would be fine to apply the brakes to diff input similar to RC racers. It's very rare that scale models actually need wheel independant brakes. That would also allow using direct servo input for the brake which will result in less latency for remote control.
The problem with this solution is that, the U-joints will be extremely stressed and can easily brake
Imagine using Lego's RC controller and receiver to power two identical motors for the two axles, making the car all-wheel drive. Also (just a thought), we could add an electric motor to turn the steering column at the point demonstrated in this video, and control it using a controller specifically made for not continuous turning, but only for short bursts, to turn the axles. Great video.
Latest gen Lego motors ("Control+") with bluetooth control module can run all motors as electric motors or servos as needed. Of course, it's not compatible with older power functions parts so you need to get all new motors in addition to the controller.
Use Controlz Android app to configure servo angles and motor speeds. Cheapest set to get two motors and the controller is Lego 42109. If you also want suspension parts, get Lego 42099. The Controlz app can control multiple control modules and each module can control up to 4 motor units (each configured as servo or motor).
Lego 42124 (Off-Road Buggy) is supposed to be introduced soon and if it's priced low it might be the cheapest way to get Control+ parts.
If you have compatible controller (e.g. PS4 controller), BrickController 2 is also a good way to control new Lego parts. You still need an Android phone as a proxy, though. I think BrickController 2 can also work with iPhone.
I'm not a huge fan of C+ system, you can't stack connections, those motors are huge in comparison to already not so small PF motors and they are quite pricey. The only C+ advantage is already mentioned by you encoder and ability to use them as servos, but this function still barely works with Lego apps as far as I know. So I'll stick with old good PF
I'm glad youtube recommended me this, awsome work, subbed
How come you only have 800 subs, you deserve much more, subscribed to support your great channel
This is pretty amazing.
Wow this is a very good idea! Maybe this will end up in some of my mocs ;)
Nice and very compact !
Amazing work!
really cool !
Build a Lego Technic Dodge Demon around this design...too perfect I'd say!

Looking forward to seeing more! Many thanks for sharing
Awesome job
Excellent! I don’t see many videos that have working disc brakes in axles, I’ve mainly seen sheepo cover it
Nice one
This is basically everything you could possibly want your front axle to do
new version is even better! ua-cam.com/video/TyOA9fpBFQs/v-deo.html
Wow. Good work. Very well done ;)
thank you sir, I'm a big fan of your work
Ur a genious!
You Are a genius!
total bonkers my dude
This is definitely on the 'If I Win a Million Dollars' list. This right here.
That’s crazy that this has break pads that’s kinda insane am I the only one that thinks that
Nice, correct disk for a disc btw
Cool 4 functions
This is a great design man, crazy the detail that's in it. There is only one thing I would change personally that being what your using for a brake pad. A softer material for the brake pads would make them work MUCH better. Alternatively you could change the design so more of the brake pads surface area touch the rotor. But anyways amazing design.
It's working surprisingly efficiently because the pad isn't pressed exactly parallely to disc surface (bigger force is applied to higher connecting point, so it twists a little bit up). Thanks to that, the pad catches stud-gaps on disk and stops it.
Do you know if you are using a leading brake system? ie does the disc rotate into side of the pad with the bigger force (leading) or away from that side (trailing)
This is just like the steering and suspension of my LEGO Porsche
can you show me your version?
Exttero's Lego Technic Creations I have a video of it on my channel a orange Porsche yet I can’t take out the suspension
it's a official version or your mod?
You should do a car and sent it to lego. I will definetly buy it. Good job bro
That’s awesome!!! I’d prefer RWD :P absolutely amazing work
Genius
If you only on the back axle build this by a very fast car, you can drift very nice!
you can now refresh this beautiful idea with de discs brakes for the new bugatti chiron set and it's gonna be perfect. ;)
I'm currently building Rimac Concept S, it's even more amazing than Bugatti
What an amazing model. I think you could improve the performance of the brakes but maybe the estectics are more important since it's a model. There are lego vinking shields and rubber axel holders. I think you could get the brakes to work better with that configuration. Hope you can utilize this in a lego car.
tried my best, but sadly those small pneumatics cylinders don't have enough strength
ua-cam.com/video/TyOA9fpBFQs/v-deo.html
Hey great video! You should try making a transmission with a working clutch based off of pneumatics!
Really good idea, definitely will think about this👍👌
This just showed me how brakes work!!! I always thought the discs pressed on the wheel hub but never knew what the calipers were
Shawn Julian The poor rims...
Seeing you use those ball joints gives me anxiety lol
great, now how do you build it
Genius!!!
This is really great, do you come up with all of the ideas yourself?
I've learned a lot by watching nicjasno's videos, but designed this one all by myself
I'm really impressed. I'll try to come up with something just as cool as this. Keep up the good work!
@Exttero's Lego Technic Creations I had this idea where you use the pneumatic cylinders in place of shocks for the suspension and then you can use them to adjust the ride height while still having the pop back of the shocks. If you see this and can create a moc of this that would be awesome.
Had very similar idea. I've put one custom shock absorber and one small pneumatic cylinder per wheel to make pneumatic system for adjustable ride height, and it works quite nicely. Video is coming someday hopefully 😁
That's really cool but I feel like you should of built a forward wheel drive car using this to test out the brakes
It's in the making 😉
Make a solid axle with a working panhard
I would like to build this myself. Do you have some instructions on how to build it? thanks
buy the finest sandpapaer you can get and cut out 2 circles with a hole in the middle and glue/teip it to the rotor and do the same to the pad, makes better friktion and easier barking
Nice work! Is the wear on the brake elements bad though?
Terence Tsang if there is that just makes it even cooler. But probably not unless it is used a crap ton.
He could’ve made a r6 drone lol regardless of that it’s sick as hell
Just gonna wait till someone builds a all lego awd rc rally car with brake discs.
As you wish! 😉
That remembers me of the 42110
how does this work, when the steering links and the connections of the wheels to the axle are not aligned? i can't manage to do that, without the wheels being offset when suspended.
This axleset works best when it's about half-way compressed. These are adventages of positive caster angle and king pin. Thanks to them, car stais driving straight without turning itself and has better grip while cornering.
Hm did you slightly base the steering component off of the rally car set?
i built it few months before release of 42077, so no I didn't😊
Wow, verry smart.
Do you have the instructions to?
You need to balance that driver side wheel ! Lol
I used to make things like this out of legos a few years back. The reason I stopped is because of frustration. Sadly.
Nearby perfect ! But i would use dampers for the breaks, it's better!
How would you control those dampers?
@@extteroslegotechniccreatio4845
Pneumatic
You are the best Lego-engineer! Are you interested in RC cars too?
I was never really into it, but maybe i'll try. It looks like a lot of fun
Amazing. Now do hydropneumatic suspension
Great idea! If you want to see it please support me by buying my instructions so I can afford pneumatic cylinders, they are quite pricey 😟😅
Nicem but why don't you use a lego rubber piece to prevent wear?
they were too soft and
in addition to the functionality, I wanted to keep the autnetic look of brakes. I can ensure you, that rubber pices would be consumed much quicker than regular pieces
How meany miles before you have to change the brake pads?
Two yies later: I Built A Fully funkcional CAR
almost ;) progress going slowly, but you can check out new version of this axle ua-cam.com/video/TyOA9fpBFQs/v-deo.html
I'd like to see this on a lego car
*and i'm over here struggling to make a basic skyscraper*
Imprssive
You know you can add three modified pegs with studs
and use a flat 1x3 plate so the brake calliper looks better
I'm not really into modifying bricks, and in my opinion my solution is optimal, because real brake callipers ain't so flat
But you haven’t done an axle with:
Positive caster, udjustable ride hight, brakes,independent suspension,Ackerman steering with virtual pivot point,drive,automatically locking differential, toe angle and camber angle.
Lol wonder if that’s possible.
A lot of that is coming in my next MOC. ;)
Virtual pivot point is achievable only by using multilink setup suspension, which is very weak in lego.
Further, there is no such thing as automatically locking differential, maybe you mean limited slip differential?
All in all, I think I was really colse to your wish, with not containing only 3 out of 10 functions ;)
After watching this video the 4096 times i still can't figure out how to do a one one Bugatti Disc-brake.
Does this have any update?
I'm not sure if it is even possible, because you need to use standard lego hubs to mount Bugatti discs
Can u pls tell me wut piece number the tire rim and wheel was? Great video
These are wheels from Porsche, 23799 and 23800
YES thank u
I was lookin for race car wheels
I tried to build the same thing but had to make it twice the size.
Dual calipers please?
In the year 31589, when the scientists are finally done watching the entirety of UA-cam, they will come to no indisputable conclusions safe for one.
Every single human who was any good with Technic had an utterly obnoxious taste in music.
It' not so easy to find free-to use music and it's impossible to please everyone, but if you have any suggestions i'd like to hear them
Youll need to change the angle of your steering linkage to prevent bump steer
The breaking will stress the motor.But overall,good work
thank you I use brakes while motor was running only to show that breaks actually work and have some breaking power
you can also check out my 2nd verion of complex front axle here: ua-cam.com/video/TyOA9fpBFQs/v-deo.html
Try to make a full rc Lego car with working suspension and turning
а вам не кажется что из-за трения детали будут быстро портится, и точка изгиба карданов не соответствует точке изгиба рычага, из-за этого можно сломать карданы, безусловно это отличная идея, но что из-за этого портятся детали это большой минус

How you controled the breaks?
with pneumatic switch
using two small pneumatic cylinders
so no ones gonna mention how these look like r6 drones
what you talking about hubs? i made a front without hubs just axel and spacer then the thing to hold it in then end of axel
its also set up on suspension
YES THIS IS WHAT I WAN.. wait I'm missing parts to build this. Please don't think of me as a hater but can make a front axle with the suspension spring being a one with like a little knob at the end. I will find the piece's code and put it in replies
Its 95292c01
@@oliverssimanis8345 I'm working on a 2nd better version, so stay tuned!
so maybe it's not what you were asking for, but for sure new version is much better than this one. Check it out ua-cam.com/video/TyOA9fpBFQs/v-deo.html
How can i get this
Damn bro
Damn it's got air brakes you need a class c to drive it
Would this for onto the lego technic Porsche gt3 rd?
Sorry rs
All you have to do is add a camera in the middle and you have the drones from Rainbow 6 Seige
did you guys noticed that the video came on the 1st April?
This for you formula one
So this is basicaly a rainbow 6 drone?
idk, kinda looks like a six siege drone
How?
next up.
Fortnite borgar - LEGO Technic (MOC)
I saw the thumbnail and thought it was a seeker mine from black ops 4
Me: NO! You can't design breaks like that! That's now how that works!!!
Lego creator: Hah hah, lego brakes go brrrrt
Lol, on a more serious note. Brake pads go on against the disk. Not brake pad on the outside. It kind of just looks odd to me.
Like it a lot tho.
Better not to use metal drum or pads it will scratch the plastic
