Alright time for the weekend update.
I have been playing around with the rear suspension some, because my shocks are short 12 inch I really wanted to take advantage of the extra travel the springs. Could provide, there is a few ways to do this.
One would be mounting them to the axle at a perpendicular angle like this
But the issue is that I loose out on the extra travel.. There really isn't many bad things about this besides the space it can take up inside.
One other way is to leverage the shock somehow.
Mezzanine style suspension is basically a reverse trailing arm.
As you can see this consumes a huge amount of space.. Now if I was going to use this arrangement I would change a lot of this but for mockup I threw it together. Kind of like a proof of concept.
Another way to leverage the shock is cantilevered. A lot of the time the issues with this are much worse than mounting the shock at a steep angle.. It's very hard to tune a suspension that has a rate falling and rising as it moves..
But my good buddy Scott better known as secutright helped me figure out (actually did the math) (he's the brains behind this) how to properly design one that is linear. I sought this because I have a bypass shock so I don't need a rising rate, I can create the progression with the shock.
Here you can see the lever. It's 1.3:1 ratio, the goal was simple, create the lever to provide 16 inches of travel from a 12 inch shock.
I napped out the motion ratio, this will show you visually the curve of the cantilever. It also confirms it is perfectly linear. This is important for the performance.

We are in the process of designing a plate style cantilever that fits under the bed. More to come stay tuned!
