Small suspension

[Stephen Provoost]

Hello,

I'm trying to make a MOC of the 8258 crane truck. But now i'm looking for a small suspension method for the back wheels. It has double wheels on each axle and a differential in the middle, so there's not much space left. Does anyone of you had ideas of how I can make it very compact?

I've been looking around on brickshelf and I found this, but I think it's to hard to get a smooth suspenion.

Thank you in advance for your time

You could use a rubber band,making it slack enough but still tight for it to stay in place should do the trick.

Hello,

I've made an example as on the link but it is to hard, and I don't actually know what kind of rubber band he is using on the picture.... Do you have a clue?

It looks like a rubber washer,a pumbing shop or a diy shop should have them,i don't know if you could use a lego tyre instead of a washer?

did you that about the rear axle in the 8081

maybe this double axle is something for you. it is not spring damped, but makes a good ground contact for trucks with 19 studs width

It looks to me like it could be a Lego tyre turned inside out

this is very well made. But he uses a couple of special pieces.... I will try to make it without the special pieces.

Thank you for you time to search it.

yes I have the 8081 but the rear axle-suspension is 'to simple' to use in my moc.

Yes, it is. The author himself said this on our forum.

You can click the button "go buy it" which will redirect you to the seller's page. once there you can add items to your cart and when you "checkout", the seller will send you an email with his Paypal address (assuming you selected paypal as your billing method) to which you can send the money to.

hope this helps!

i have ordered the pieces I need. I've been looking around on your brickshelf account, I must say it's very impressing :)

the most effective way ive seen is to attach the wishbones to the hole tha rotetes, there is spring so when you twist the axle in the hole it returns back to the center

the part is this:

I used these on my current project which is a car that has working suspention, steering, braking,, engine and diffs, etc while driving upside down and right side up

This means the suspention needs to have negative and positive stroke, the part shown above can achive +90 degres max of travel and 9 degres max of travel, it is set to 0 degree as dafault.
