Air bag diagrams

[N2TRUX]

I have seen some pretty nice air bag diagrams posted her recently in various threads. Lets try to get them all on one thread. Be sure to post a link to where they came from in case there is more info available on the linked site.


Here are a couple I have found-

I understand the air diagram and the wireing diagram, But how do you regulate the pressure in the bags ? Is this done manually each time that you fill the bags keeping an eye on the pressure gauge ?

Or is there a way to hit one switch and have all the bags inflate to a predetermined pressure and another switch to dump ? I have seen the pictures of controllers that have 8 switches and that seems a little complex !

Well, there isnt 8 switches, for an independant wheel system like these diagrams show there is only 4. Up/Down for each wheel. You could rig something like you are talking about, but it would require lots of sensors and elecrical work.

Getting 4 wheels at a set PSI isnt hard. Just watch the gauge, air up or down and drive.

Yes, if you air it out every time you park, then you will have to set it to ride height every time you roll. Most of the mechanical gauges have dual needles so you only need two gauges on a way way system though. Digital gauges show the air pressure at each corner.

Yes you can wire an extra switch to raise or dump your sytem. You will have to have a seperate set of relays to do this though. It would require 4 per function, or one per function if you added diodes in the circuit.

It won't go to a predetermined pressure unless you put a seperate pressure regulator in that circuit though.


Here's a pic of the control panel on my 77. The switch in the center is used to dump the system.....
