Solid leaf-springs

[Lipko]

Creep is important in certain metals, especially at extremely high temperatures, but it is not a factor in LEGO parts. If a LEGO torsion spring does not permanently deform immediately under load, it is unlikely to do so even after years of support.

Thanks for the info. I thought that most plastic materials as wood are likely to creep.

Some 5.5 axles with stop do creep immediatelly after exposed to torsion. They're really soft, and i have to test every one before it gets installed into an engine.

Just found this by George Staples: http://mocpages.com/moc.php/316153 scroll down for the leaf springs looks pretty realistic in my opinion (you may wish to comment differently, I'm no expert )

I built a moc with flex axles and it worked great. I fixed them on the axle different. If I can find the old pictures I'll post them or I'll rebuild the modules to show. I can't see bending plates. Most truck leaf springs are curved, I could be wrong though.

Flexcables work great for simulating leafsprings! Especially if you build vehicles that originally has supporting shock absorbers/coil springs. Then the flexcables only act as stabilizers, yet they simulate the excact movement of real leafsprings.

Ta da!

I am needing to build semi elliptic leaf spring suspension on my rear axle of my supercar, and I am impressed with the result.

I'm not sure if this is completely accurate and correct, but it seem to work

Looks nice! But this will not work on a heavy vehicle. You will need panhard rods though, to keep the axle in place and from swinging side to side.

I have bent the hose too far however, might want to use flex axles (and yes I have only built it on one side of the axle so far )

Very cool. Good job.

i like the updated one more, it is more compact!

That Looks Amazing. All you need is the Lego equivalent of a U-bolt and you have it. You could slip a metal rod on the inside of the tube to strengthen it some more.

Brilliant idea, i think i have some wire somewhere that will fit... *kicks self for not being a purist*

Clever idea, just needs some refining

In June of 2010 Nico made a Jeep with Flex Axles for Leaf Springs. I am surprised no one else mentioned his creation.

Didn't know about that one...

Also, Sheepo has made his version of leaf spring suspension (http://www.sheepo.es/2013/04/mps-rear-axle-iv-live-axle-with-leaf.html) after I suggested him to build it. I have built it and I must say it works very well
