hydraulic steering question

Hey guys and gals. I was thinking of playing with some cylinders i have laying around. Both cylinders are exactly the same and this will be for offroad only. If i was to take 1 cylinder and hook it to the pitman arm and hook the other to the link on the axle cross the hoses i should get the same force out from the axle cylinder as i put into the cylinder on the pitman arm. Would this be correct? Ofcourse im not factoring in cylinder drag but, would this work?

You would not want to cross the hoses as the push and pull piston area's are different and it would move faster/farther one way and slower/less the other. If you are 100% air free, then they should equalize movement.

So your trying to make a hydro assist? Why not just run a simple cylinder off your tie rod. Two cylinders running together will need to be filled at the with same amounts of fluids, another words You can't have one Cyl fill up the boby side while the other fills the chrome or rod side.
Plus your asking alot from a steering box ( which is not a metering or orbital valve ) to direct all this fluid. What volume loss will you get? Can you time or phase the fluid to your speed of steering?

Kiss, ( keep it simple stupid) is what is needed for a hydro assist or a full hydro set up. To many hoses and Cyl create fluid heat and volume loss which will drag or slow steering speeds.

Very true im just experimenting with some stuff i have laying around. I have read that i will loose the steering feel aswell if i do it. Just want to see what it would do. Im not putting it on the road just for playing around.
