Just use it in place of the ball joint:

Here's a nifty trick I found. You can use the click hinge part 57360 as the drive CV joint for geared and ungeared hubs: They can work up to some 25-30-ish degrees and will not slip easy. Using this part, you can reduce independent suspension width by as much as 4 studs!

Lubrication...

Of course now with the upcoming 3L suspension arm, smaller suspension setups will open up even more.

It does not colide, because the bottom arm moves away from the CV joint.

Because a 5L suspension arm would colide with the CV joint. Thanks to everyone for the praise.

As someone who also miniaturized a set full of functions, I can see you put a lot of effort not only in miniaturizing, but also finding alternatives for pneumatic functions. Well done!

Good find! I think this is officially the model with the lowest placed shock absorbers Also notice, that the ?KERS? is only engaged in one of the gears.

Hope everyone had nice holidays and wish you all the best in the upcoming year! I found some time today to record and edit another model I built for the 2024 Rolug Challenge. Basically the rules stated to build a pickup truck using 62.4 tires powered by a maximum of 2 L motors. After thinking of many different brands including Toyota Hilux, Suzuki Jimny and Hummer H1, I decided on a Hummer EV for the following reasons: The real car is big... Like seriously massive, which gave me well needed space, especially the width Real deal uses independent suspension on all wheels, which i really wanted to replicate at this scale All wheel steering which is a rare, yet really useful feature It's electric, so I didn't have to cram in a fake engine Next I calculated the scale by dividing the size of the wheels to the 62.4 LEGO ones and rounding it to 1:14. Afterwards I took some time to find a 3D model online, modify it in Blender to remove doors one one side and importing it to LDD. While the import was not perfect due to some random flipped nromals, it was good enough to be used as a reference. Agter a ew days of building in LDD, I came up with the following features and functions: Accurate 1:14 representation of a Hummer EV Pickup All wheel drive- Drive powered by 2 Power Functions L motors All wheel steering powered by a Powered Up L motor with different steering angles Powered and controlled by a BuWizz 3.0 Independent suspension on all wheels Working steering wheel Openable doors, tailgate and bonnet Detailed interior with seats, bench and center console Very stiff and robust chassis design Final version is built out of 1431 parts Measures 39 x 16 x 14,5 cm Weight of just over 1 kg Here's how the finished digital model looks like using the 3D reference: And without the reference: I am really proud of the suspension system which uses the 5 studded double headed CV joints, 5L and 6L suspension arms and old, hubs: Finally it was time to build the real one, and isn't she a beauty: I'm really proud how spacious and clean the bed is in the back, you can fit a lot of stuff there: Photo with everything opened up: And the underside. Notice the 16L drive axle going through a 5x11 panel, powering the FWD: And of course here's a video showinf the model in action: Finally you can download the LDD file here: https://bricksafe.com/files/Zblj/114-lego-hummer-ev/Hummer EV.lxf LDD upgrade guide: To wrap it up, I'm really happy how well it turned out. Even though it's a big, chonky boy, the performance is really good due to the simple driveline and thanks to AWS it's actually quite nimble. The only bad side I'd say is the use of no longer used parts and the slightly exposed drive gears. P.S. Would this post be better as a standalone topic?

I think I just figured out what those gear assembly is! A coaxial drive for a helicopter or such, both gears are driven in opposite directions by a third, smaller gear or maybe even the small yellow one from Daytona diff!

Look what i also found: https://euipo.europa.eu/eSearch/#details/designs/015085679-0004

Indeed, they are both used in both new F1 cars!

Could these form a longitudual assembly like a differential? Maybe something like a Tatra uses?

Yes, they are half a stud thick, but very, very flexible. Not only do they use less material than normal half beams, they also seem to be made out of a softer plastic.

What an amazing find! Seems like it's a version they use for building the 3D models and instructions?

Some brilliant ideas right there, can't wait to see what you come up with next.

Well done, Aurora. I can't wait to see it in real life. Only thing I would recommend is switching the drive gears to gain more torque at expense of top speed.

Axle width is 2 studs wider than zetros, so yes, 15 studs. Yes, the servo can steer all of them with ease thanks to the very long steering arms, you can see it steer under very high load at 9:30.

No worries. As stated in video, I plan to upgrade motors to BuWizz ones and thereby get rid of at least 9 gears, reduce weight and increase power. Also, found some time to create a picture of the driveline: And the steering system:

Yes, because it can output 7A max, comapred to 800mA limit of normal battery boxes.

No, a single BuWizz 3.0.

The rules stated maximum of 4 motors for driving and L motors were the best compromise. Thank you for the praise.
