hello-

this is NOT for my honda. However, if I were to make one of these air aprings...



What could I make the rubber bellow part out of? Does anyone know a tiresize that I could cut the top and bottom off to fit that?

I dont feel like paying 200 bucks at mcmaster, or 100 or so for the one i found.

Before you <FONT COLOR="red">flame</FONT> this is NOT for a car... but since this is the suspension forum, i figured i would ask here.

Any insight you can give me would be greatly appreciated...

 

dude get air struts or cans/cylinders... and you could get 1 bag for $65 at the least. look around more

hmm.. this is interesting... what is it for?

a smaller tire.. u could try something like a forklift tire or some kind of go-cart tire.

those type of airbags are also found on 18-wheelers.

 

Zvic- its for my senior physics project. I need something to collapse relatively small, and 'inflate' or expand upwards (and NOT radially outwards) when pressure is introduced.

I have several limiting factors (pressure, voltage, etc). I already have plans for an 'air spring' made out of aluminum and rubber, but the one I require is a bit different than the above pictured.

Picture, if you will... a tall stretched donut. I need an 'air spring' but with a hole in the middle... So its just an annulus that expands upwards. I was going to make something like the one pictured above, and just put another set of bellows on the ID of the annulus.


Sooo... any ideas? feel free to PM me or anything

 

strut bags

 

most of the airbags are going to xpand radially when pressure is introduced to it.. I know the firestone bags do.. The only bags that dont expand radially and only expand vertically are going to be slam specialties bags... They are good bags the only problem with them is they are so thick that you can actually stand on a unaired bag and it will barely collapse. firestone bags will compress alot more but thats why they give when air is introduced...

 

slam specialties (sp) rock if you wanna spend up to $85 a bag..lol, but they do rock, a buddy of mine had em on his dually

 

Lawn tractor tire or inner tube
bicycle inner tube wrapped in a coil

If it doesn't have to lift much weight make something out of leather like vinyl.

**** i didnt see this.

Well the radial expansion wil be limited by the ID of a cylinder...

If I put the firestone bag in a cylinder, when it was inflated.. do you think the edge would bind up on the ID of the cylinder it was in?

thanks

If you mean bind up to the point wherre it wont move anywhere except out, i dont think so just because even though it is a firestone bag it is still pretty thick rubber but with enough pressure im sure you could get it to.. at some point either the bag will give or the cylinder will unless the cylinder is metla of course, but it depends on what size bag you get.. Like firestone 2600 are only made for 2600 pounds of weight put on the bag im not sure what that calculates out to as far as psi but something will give but i do not know for a fact that the lip wil turn outwards..
