Air shocks

rollnhvy · Jan 20, 2008

does anybody happen to have any pictures of what they look like on the inside. I am going to be building 4 from scratch for my samurai and was wondering what the pistons look like and used for valving.

really:eeek:

damn you must really be able to fab.

Your going to build your own but you have no idea of what is in them?

That sounds like a winner of an idea :haha: :haha: :haha: :haha:

You must have access to a pretty sweet Mill...

seriously, If your time is worth anything at all, it is cheaper to just buy them. Not only for the initial setup, but for all the experimentation of getting things just right. I could buy 50 sets for what my time is worth.

You do not value yourself enough.

Do you guys have any pictures of the inside of a nuclier reactor? I'm tired of paying my power bill, so I thought I'd just fab my own from scratch...:fawkdancesmiley:

well since i can make hydraulic cylinders and air cylinders all day long i figured i give making my own shocks a try....... And yes we have 4 lathes and 2 mills :beer:

Lets see if you can get all the theory that goes into those valves even close... My dynamics prof. is in awe of the ones we run, and his career specialty is Vehicle dynamics...

So, in other words, just buy some...

buy them for the parts availability and tuning guides that already exist

Only one I have, from a post about the negative springs in them

CHOP SHOP · Jan 21, 2008

I have seen hydraulic cylinders used as shocks. the owner used a valve between the two ports to control motion the same in each direction (kinda like a bypass). I have also seen hydro cylinders attatched to a lever to raise and lower each corner independently. when the lever for each wheel is in the middle position it allows the cylinder to float on compressed nitrogen, and having a valve inline to adjust how fast the fluid can flow (dampning).

start making some **** man. all the companies that make the **** are run by humans like everybody. hell if they work, maybe Ill buy some!:awesomework:

its not brain surgery, nobody is going to get hurt if it dont work right?:beer:

fawk the doubters and burn the haters:fawkdancesmiley: :fawkdancesmiley:

as far as i know hydraulic rams are used as springs, not as absorbers, there is no valving inside them just a piston.

rollnhvy · Jan 21, 2008

hey brad the hydraulic cylinder you mentioned is comonly used on tilt deck trailers..... they use a hose from the rod port to the base port with a common needle valve in between so you can choke down the orifice and control the rate the fluid can transfer from port to port

Ok looks like i am really gonna try this from scratch was just looking for some design info for a place to start......:beer:

CHOP SHOP · Jan 21, 2008

this as simple as I can explain it. I wasnt talking about internal valving.

if used as a spring you only need a single acting ram then and just put a valve inline with the hose to quicken or slow flow.

lowriders have used slow down valve to control how fast or slow the car drops.:awesomework:

rollnhvy · Jan 21, 2008

hehehe that is so farm tractor.... I really need a internal flow control machined into the piston that is pressure compinsated to vary with the load. That way it will auto adjust to the load rate applied at the time..... I was thinking the high end shocks like king and fox ran a similier system in them. Just wanted to see one a part to give me some design idea's. I am not real big in springs in cylinders if they brake they scratch the cylinder bore beyond re-honing

CHOP SHOP · Jan 22, 2008

when i was referring to springs I was thinking of a setup like this. I seen this truck drive into the luxor and wait for valet parking. it has rams connected to bags so when aired up it lifts. the other setup i do not have pics of, it uses a ram with a hose connected to a tank with pressurized nitrogen for spring pressure.

your right on with the trailer comparison, i couldnt explain it better. looks like your going to build yours a little cooler though.:awesomework:
