I’ve been working on this truck concept for a few years and finally got to the point where I want to start sharing it.
Introduction:
It’s a spring-based design that doesn’t use a traditional kingpin or pivot bolt.
Originally I was envisioning this as a way to make an All-Terrain mountainboard type truck, with suspension. But I decided that the easiest and cheapest way for me to design and prototype it was making the smallest version I could, and I had just gotten my first 3D printer. And so the AT-Mini was born.
Here is the first video I made, with the original proof of concept:
For years even prior to this, I’d been playing around with torsion trucks, and had been completely stumped on how to make torsion springs trucks work without breaking.
Designs like this have been around since the 70’s, and I’d been fascinated by them for a while.
But they never took off for several reasons, but the biggest is because they break.
This proof of concept video was the big “Aha!” moment, where I realized what was actually going on to cause this style to never work out. And with a fresh new lead, I started out making.
I’ll be updating this thread as we go along
