Thread: Independent Suspension Design

Spent a large portion of the morning working out the location of the shocks, this was not as simple as first thought. Shock travel in both directions, ensure the shock is not topping out or bottoming out and max stroke length without hitting any other part of the suspension. Have to order a set of limiting straps.
With all that worked out we finished tacking on all the other bits that make up the suspension rib.

The trailer sat out side with its 700Kg static load over night with nothing changed or moved or broken this morning. As we removed the load I dumped air out of the air spring. The photo shows were the wheels were sitting with no load and only 5PSI of air in the springs.

hmmmmmm

Flash shocks for a trailer!

rover, the hmmmm worries me!

I was looking for a shock that would cop a flogging & would not give up. I run Billies on my trucks & love them, but for the some coin i got big buggers with remote canisters, should do the job + i love shinny bits

Cheers

Have you thought about any form of auto leveling for the airbags? Maybe a proportioning valve or something to reduce or increase the pressure via an arm attached to the swing arm? Just wondering how you are going to manage this so the tyres don't get destroyed?

Looking good though, keep the pics coming.

I promise you I love this build
I like the central spine - I like the tube you have used
I like the "ribs" supporting the outside structure
I like the overall vibe of the thing

I just couldnt be satisfied with that suspension geometry
I fear this thing as you show it will ride poorly (left to right load transfer) and it will wear tyres horribly

Is it possible to perhaps re design the swing arms to incorporate an upper link arm from your central pivot???
Still keep your centrally located geometry but using upper and lower links (think mcpherson strut) to ensure consistent alignment throughout wheel travel

Or alternatively make a solid axle and "one link" geometry from the central spine

I just think that NOW is the time to sort the geometry issue not in 100km when you realise you are not happy with it???

Hi Steve,

I really appreciate you honest input to my build.

My chassis design idea has come from the Tatra king frame suspension design.
It is not identical but very similar in operation.
Have a peek at this video, these guys have been using this design for many years. Time will tell if i have got it right or failed badly.

I am looking into an auto levelling kit for the future.

Auto leveling. An air compressor and two schrader valves, it is not like it is a luxury vehicle that needs to self level after putting a trailer behind it. I suspect the trailer will be used with a similar mass most of the time and self leveling would be an unnecessary complication. KISS.

But it would be cool to see it adjusting to compensate for 100 liters of water in the tank.
