Tough Axles.LXF I just wanted to share these! @effermandid 90% of the work. I did some small modifications like the servo and CV joint frame. These axles are pretty tough and can take abuse. You can also take the 5x7 frame out of the middle and replace it with a H frame if you need more connection points.

Can't wait for the video!

It's amazing how close it is to the real thing.. Are you using a model scaler? scaler <--

This is the reason why EB needs a period of time where new members can't post till a timer goes up. Let's say 1 week of lurking before posting.

LDD complete for both axles.. Still need a suspension.. EDIT: i might make the front drive shaft a couple of studs shorter for better steering radius.

How's the steering? Can you get the angles the real thing can? Also is it possible to change the cables into chains instead? @Thirdwiggmade a moc like this before and he used chains. https://thirdwigg.com/2016/03/14/kalmar-dcg180-9/ No idea how much weight the chains can handle though.

This is what i could come up with.. It works well going up and down and there were good bit of options how to attach it.. But when i want the axle to tilt side to side, it moves diagonally. It refuses to go properly sideways. It wants to tilt the other wheel backwards and other wheel forwards. Somebody said that it's very simple and easy because there are many mounting options but i can't figure out how.

That's pretty amazing. If this tilt mechanism would be larger, could it be made driven?

Lego has really improved on their designs over the years. That truck looks amazing. Wish it was a little bit bigger scale so it could be RC'd easily.

Here is my current progress: The piece of chassis and springs are just a placeholder and not the finished thing. But yeah that's a finished rear axle. I will be having a short drive shaft for the rear and very long drive shaft going to the front like the SISU has in real life. I kinda don't want to have the drive shafts obstructed by suspension links. So i need to figure out a way to attach the axles from the top. Suggestions are welcome.

@Zerobricks Yeah i make a lot of help threads.. Most of the time i need something very specific for a moc. Build it. Figure out that the moc doesn't end up how i wanted it to be and i end up disassembling it. Rinse and repeat. 90% of the time it's a "i don't have parts for this" issue. Now that i have lots of parts. It's becoming more of a: "i want it to look a certain way and to function a certain way" type of a deal. The help threads are just a tip of an iceberg. I've been tinkering with a project for longer and when i get stuck for too long, i make a help thread. If the issue is resolved then i'll continue with the moc. If i actually finish the thing, i'll post a moc in my own projects thread. I never intended posting the finished moc in the help thread. But don't get fooled. I read every single thing on the help thread. I have them bookmarked. I do test things that people show me. But in the end it's my call if it looks the way i want it on my moc. I've been sending PM's to @efferman a lot and he has been a massive help coming up with specific scaled specific purpose axles. God bless hes soul. I'm still working on the current SISU project. I haven't given up on it. I copied and modified the axle efferman suggested and now i have a functioning rear axle that's durable and looks good. Now i'm going to tackle the front axle next. Back on topic: @howitzer Any progress on the axle?

I didn't claim tractors don't have suspensions. Since you're going to be a nitpicker and act like you do not understand sayings like for example: "beat around the bush" or "break a leg" Then let me tell you. There is a saying that "The only suspension a tractor has is the seat" Meaning old timy tractors that had large springs under the driver seat. They usually were very rough to drive and the help from that seat was pretty much better than nothing. If you're trying to build a tractor for your kid to play with, the only "suspension" it would need would be a swing axle in the front. That way you get maximum durability and at least some offroad capability. But i know you knew what my point was and just wanted to feel better about yourself that you made a person over the internet "learn a fact". Thank you i guess?

Don't nitpick son. We all know the point i meant.

Guess it could be "inspired by".. Going with solid axles using legos would pretty much make the axle so low that it would drag dirt as it moves. So portal axles is a must..

Hmm.. I kinda want to preserve that distinctive long drive shaft that goes to the front axle. I need to rethink this..

Only suspensions tractors have is on the drivers chair. They usually have a swing axle on the front.

I think the boom needs to be just 1 stud closer.

Those image links look like deep web sites

There is a difference in saying: Oh there are so many errors on your design. Let me point out how this and this part doesn't work because the parts would be fighting each other and stressing parts to breaking. instead of saying Your stuff hurts my eyes. Please be kind and disassemble it. It's nothing about saying huff you're just a snowflake and can't take criticism. It's just being mean. But i guess being famous on the community and being one of the "big builders" out there means that you can't possibly do anything wrong yourself. howitzer is a newbie to this forum, let's be honest. It's very discouraging to be chewed on by saying your build literally hurts my eyes, it's that bad. Yes he is an adult and actually can take it. But what if it was a 10 year old posting hes first ever moc and thinking he was actually innovative and creating something new that nobody else though of. Then being told off by one of the biggest community members to pretty much not even try.

Man @Sariel is toxic. So much criticism but no actual solutions offered. Basically pointless comment. If it takes no effort then why not post a solution.

@filsawgood's rock rod front axle looks very promising. I wonder if it can be widened by 2 studs. I think i'll give it a shot and see how it works. EDIT: After some tinkering, this is what i built!

I like that axle andy posted. However i still want it to be servo steered. But it sure gives ideas.

I built it in real life. It does work as suspension geometry but the drive shaft is the next problem. Also the servo would interfere with that top ball joint cup part.

Ehh.. I wish i had some reference to copy from. So far i haven't found any axles like this. Almost every one of the axles that use the H frame use the ball joint fork part. EDIT: I guess this method would keep the H frame going up and down horizontally.. Ahh.. i'm so bad at making axles.

Yeah i guess using a linkage is a better idea to have the axle look less cluttered. Servo sitting on top would make it very bulky. I also though how using the mercedes benz type of deal where the linkage moves front to back for steering. But then i'd have to mount the servo sideways. Not sure how it would interfere with the suspension linkages tho.
