Hi,
First of all sorry, not about machining this topic. Every now and then I need to transfer delicate goods and my current trailer has leaf springs so depending on load it could give quite harsh ride. So what I was planning is to convert it to use air suspension. I see there are affordable air bags so it wouldn’t break a bank. I was planning to have very minimalistic design (read cheap). Bags, tank and valve. No fancy electronics or pump. So having fairly big tank with Schrader valve I’d just fill it with as much as the compressor at home can produce (< 10bar / 145 psi) before the trip. When trailer is loaded, manually from valve adjust the pressure for correct drive height. That tank should be plenty for few adjustments and in emergency can fill it from gas station. I’m assuming if no leaks and load is static, pressure can maintain static as well. Am I right?
I’ve tried to google how these systems work with little luck. My hesitation is on the air volume for suspension. So I was thinking that is the air volume inside the bags enough for super smooth ride? It gets progressive but does it get too progressive with small bags? So I was planning to have two tanks. One which is at max pressure and another which is at the same atmosphere as the bags. This way the progressivity would be reduced drastically as the air volume under load is considerable larger. However air line diameter restricts the airflow somewhat and that brings progressivity, but is it considerable amount? Or would this second tank idea just ruin it and have the suspension bottom out? Thoughts?
Thanks for help.
