It would wear out in hours and break completely... Besides for cars you can get much smoother gear based transitions that allow free hanging suspension.
Seconded. That one shot of you rotating the joint at the 90 degree angle was the best part of the video, and, as mentioned above, the most satisfying. You get a subscription from me.
I'm glad to see I'm not the only one with cracks in my legos like on the end of those joints. Really makes me sad when they do that and replacing just that piece or even a set of those pieces doesn't work out too well.
A simple concept demonstrated generates a flood of ideas. I wouldn't have been able to come up with this. Then again, I haven't built any LEGO sets for years.
So satisfying to watch... if you made a gizmo that just spins one end while the other end just revolves around in a circle, that would be so fun to watch.
Oh, I managed to get new ones since... Still, LEGO will have to carve out a bit more metal from their plastic injection molds in order to reinforce the parts a bit ;)
Lego Technic Mastery that gives me an idea. What if I were to somehow reverse engineer it as an axle instead of a bush? That way it's less likely to crack. And I am aware that cv joints exist in Lego, but they don't have as much free movement.
Yes, I believe you could reverse engineer it, and then 3D print it to test it out ! On the other side, just reinforcing the bush section of the U-joint like conventionnal 2L axle connectors (part #6538), would work fine, as I have never seen these crack under load, with the advantage of being extendable without an extra axle connector, perhaps.
The real issue to solve with this type of joint would be somewhat high amount of torque applied to where the rods telescope from the rotors. Adding more rods could solve this issue for a given application. Your design is really cool!
Very cool! I really like the design of them; I'm always worried about breaking the ones that are pre-built (the part you have three of in one of them). I have a socket tool that is pretty much a 90 degree version of your fixed angle CV axle.
This is ingenious, it fixes the one main drawback of the standard universal joints: they get stuck at 90 degree angles. These could theoretically also be expanded to monstrous size for really heavy loads.
If you can some how add actuators to the little rods sticking out of the ends that can adjust it's hight, you can have it be controlled remotely, that's too cool!
That is amazing I thought about the speed of the joint as a kid and later understood it wasn't constant. I wish so had those red joints when I was younger.
wouldn't these have an issue maintaining a specific distance between the two arms of the joint? because of the mechanism that allows for flexing, you are also introducing a load of slide into the system.
That's probably a good thing! Usually drive trains do not want the added responsibility of wheel location for example. That's a job for suspension systems.
Quick question for ya (if I had the parts I'd be able to answer this myself but unfortunately I can't rotate this in Lego Digital Designer!) Is there a reason you use two wheels on each side? I need to make a more compact fixed angle version and I'm wondering how plausible it would be to use a single wheel and maybe a 3m or even 2m axle for each angle joint
Lego... CV... Axle... Joints. That is freaking hilarious and AWESOME!!! Now on to the torture test. How fast can they go, and how much load can they handle before self-destruction? :-)
On rear wheel drive vehicles or vehicles built for off-road conditions, it's common to see them used at the ends of axle halfshafts and driveshafts. Those are generally called a tracta or rzeppa joint. Steering columns also implement CV joints fairly commonly, but are a different type, usually a double cardan joint. Another famous and genius design implemented into lots of agricultural and industrial machinery is the Thompson CVJ, or the Thompson coupling. Apart from these uses, you can find CV joints in use in some tools, such as a jointed or swivel socket extension, allowing use of a socket at weird and unusual angles, but requiring the equal distribution of force that even a simple CV provides.
Nice, BUT... I am curious about an actual RPM test to see if they're really constant speed and not, say, three/six speed oscillations per revolution or so (as opposed to one or two for a normal joint)?
I did indeed come up with this concept on my own ^^. After uploading those, I've seen almost the same as the "Fixed Angle Joint", by another youtuber. Great minds think together ;)
I used to work at a parts store. CV axles are such a pain. They wear out so fast. Seems like every day I sold at least 1 of them. Thankfully they aren't too expensive, relatively.
@@hedgeearthridge6807 Next time that CV goes bad on my Jeep, it's Tom Woods time. No more braking the drive shaft when putting that 5.7 hemi power to the ground :D

Dude this just fucking blew my mind. This is incredible, I could watch these things turn all day...
the music and the hand moving fits together too perfect. Its just too funny but at the same time it really blows your mind
I’d love to see this used in a car to connect the drivetrain to the wheels
It would wear out in hours and break completely... Besides for cars you can get much smoother gear based transitions that allow free hanging suspension.
Some Guy yeah I know but just thought it would look cool even if it wasn’t too functional
@@DansanTutorials I'm trying to use It in my car. Video will be up hopefully in a couple weeks
I indeed am waiting for it !
The sliding of the shafts induces wear and tear. It will drastically reduce the life of the vehicle
Nice! I like how you can get 90 degree angles, also, it quite satisfying to watch! 😂👍
All About Lego This is one of the reasons I uploaded it ^^ satisfying to watch 😊
Seconded. That one shot of you rotating the joint at the 90 degree angle was the best part of the video, and, as mentioned above, the most satisfying. You get a subscription from me.
Wow thank You ! So you're a Piano improvisator too :O
More classical, but working on the improv part. That's what my channel is for. It's a slow work in progress. And yes, I was and still am a Lego guy.
Lovely ! I'd love to see more from you on YT some day ^^ Waiting for this definitely !
This is so elegant, wow
the fixed angle one really blew me away, what an unexpectedly perfect cv joint!!
I'm glad to see I'm not the only one with cracks in my legos like on the end of those joints. Really makes me sad when they do that and replacing just that piece or even a set of those pieces doesn't work out too well.
This guy is over a lego builder,he is an ENGINEER!
Its so...mesmerizing...
A simple concept demonstrated generates a flood of ideas. I wouldn't have been able to come up with this. Then again, I haven't built any LEGO sets for years.
As usual, that’s smooth and clean as perfection, very satisfying to watch and useful 😌
Great work !
You are simply genius, i got so much ideas after watching the video , too put this in very huge constructions. Thanks, all the best to you.
I never knew what these were called, but I always found them super satisfying, thank you
Ball joints: Finaly, a worthy opponent!
Ball joint got no torque though.
This might achieve a cv joint that can attach to a buggy motor without destroying it.
Best channel on TH-cam much appreciated
So satisfying to watch... if you made a gizmo that just spins one end while the other end just revolves around in a circle, that would be so fun to watch.
back here cause im bored only to notice one thing: your u joints are cracked.
Oh, I managed to get new ones since... Still, LEGO will have to carve out a bit more metal from their plastic injection molds in order to reinforce the parts a bit ;)

Is it just me or is that really satisfying.
Pure poetic art.
I love these videos. It also helps to visualize how the these things work in real life on cars and stuff.
I’m definitely going to be using the heavy duty one, it will help my designs not rip apart joints
This is mesmerizing to watch.
It’s satisfying when it’s turning because when it’s turning the rods go forwards and backwards
You've made Lego Technic dance. Impressive!
Yo that's trippy
You usually don't think of lego pieces as something that is very loose and versatile but dang!
This looks like perfect thing i ever see
This is ingenious, it fixes the one main drawback of the standard universal joints: they get stuck at 90 degree angles. These could theoretically also be expanded to monstrous size for really heavy loads.
You never fail to satisfy.
If you can some how add actuators to the little rods sticking out of the ends that can adjust it's hight, you can have it be controlled remotely, that's too cool!

Marcus M You can still be a child again for a few minutes, building those ;)
Lego Technic Mastery I just don't have time for it and all my lego is in the attic.
Simple and elegant
That is so satisfying
wouldn't these have an issue maintaining a specific distance between the two arms of the joint? because of the mechanism that allows for flexing, you are also introducing a load of slide into the system.
A big load?
That's probably a good thing! Usually drive trains do not want the added responsibility of wheel location for example. That's a job for suspension systems.
imagine using this in a bionicle moc
Super classy! Congrats!
great tune, genius joints
My brain has been blown within the first 5 seconds
God damn, so simply, but effective!
Putting springs on one side of the piston pieces may make a smoother motion -- or at least prevent them from slamming open or closed.
I think it's funny it uses actual CV joints to make a more complex CV joint.
Very nice! A fixed 90* would be cool
So cool! Thanks for showing how it's done!
great joint
Very very nice creation!!!
Thank you very much for your generous support on this one ^^
The first one blows my mind
The pink orb In my head hurts
Love it. simple and useful
Amazing idea
Just discovered your channel. Excellent stuff you've got here! Love it all!
This is cool stuff, I hope to return to building with Lego Technic some day, for now I'll keep up with your work.
As soon as I get these pieces ima use the heavy duty one for robot arms
Elegant indeed!
So satisfying.
I am here because,... actually because!
Might make use of this in robotics
This is so cool
Satisfying
Very creative!
Oh hello there recommendations!
So simple if u know how , but so genius!!!!
How do they perform under load? Do they still flow freely enough to rotate or do they bind up?
Quick question for ya (if I had the parts I'd be able to answer this myself but unfortunately I can't rotate this in Lego Digital Designer!)
Is there a reason you use two wheels on each side? I need to make a more compact fixed angle version and I'm wondering how plausible it would be to use a single wheel and maybe a 3m or even 2m axle for each angle joint
These joints would be perfect to get more angle out of a front-wheel drive or an All-wheel drive car.
am intrigued
That is crazy
Where did you get the red loose hinge pieces? I've never seen those before, what are they called?
These are awesome! Could these also be used as extendable driveshafts?
Oh yes ! I guess so !
Is this a CV joint or a just a U joint? It seems like it might not actual transmit the velocity perfectly, more like a u-joint, but it's hard to tell
Could this be done with only 2 middle piece connectors or 1 with the right joint?, or is 3 the lowest limit?
Quality design👌👌
This is nice
Can I just know if there is a practical purpose or is it just to look cool
Very nice
Smooth
Lego... CV... Axle... Joints.
That is freaking hilarious and AWESOME!!!
Now on to the torture test. How fast can they go, and how much load can they handle before self-destruction? :-)
What is that red piece for the heavy duty CV joint?
I need to know this!
And this is what they use for front wheel drive cars
No it's not they use universal joints which would only be one of those joint
Nope, universal/cross-joints only
nope just a regular ol U joint
They use U joints for RWD drive trains, CV joints for FWD combined with a Tripod joint.
@@Sav-. My jeeps got a U joint in the front
Music is based on the "in the desert you can't remember your name..." right? Can't remember the name of the song. Or is it just plagiarism?
RCmies The composer must've been ispired by "A Horse with no name" the similarities are there ^^
I definitely hear it too!
PERFECTION!!!
The builds u can do with this, tht can be used to make a base skeleton for a robot model, just gotta replace some parts for pistons
Is the velocity truly constant, or is it a sine wave, as in a u-joint?
Yes, the velocity is truly constant ! The angular distance between connection points stays constant.
So, what’s this kind of thing used for in real life?
On rear wheel drive vehicles or vehicles built for off-road conditions, it's common to see them used at the ends of axle halfshafts and driveshafts.

Not constant speed, constant velocity.
It's funny because it's not technically constant, thanks friction, killjoy
very nice!
This made me Suscribe, Keep it up!👍😃
Thank you then !
Let's use 3 pre-made CV joints to make a bigger CV joint.
Those pre-made universal joints are not constant-velocity joints.
This is Big Brain time
Those are cool, but I wonder about drive train bosses from them
Can you make a close figure out of these joints ?
I’m gonna try implementing this in my Scrap Mechanic controller powered car
The fixed axle? Did it work?
Omg so cool
Trippy
this is also called a hobson coupling I think
Brilliant!
i dont know if you invented this system but that's pretty smart !
I did indeed come up with this concept on my own ^^.

I need this to my Jeep Grand Cherokee WK. For front drive shaft CV replacement. At least this Lego version would last longer =)
