i was thinking about this at work today, you dont want a spring inline in the cable. what you need is a pulley somewhere in the middle of the cable where it is slack that is pulled out by a spring. that way the tension from the cable never travels through the spring. anybody understand what i'm saying? it will work like an idler pulley, it has to be inline with the other pulleys though. i have also seen somewhere (magazine im sure but i dont remember where) that people had used small atv winches attached to the frame to pull on the axle, compressing the suspension. this could also be adapted to the ttb, my first thought would be by mounting the winch to one axle beam in the same spot where the cable would normally be teathered. with this setup the axle could still articulate but the length of cable could be changed...if you really want to get technical you could use one winch for each side so you could adjust them individually....So what rate spring would you use and rated for what strength? They have to hold a serious amount of "bouncing" weight. 4x4junkie said he has 3-4" slack for each wheel.
The cable is completely contained within the tubing, it has no place to go but the pulley groove when it pulls tight.Now I got to thinking. How do you keep the cable in the pulley? what happens to the slack in the cable?
Now if you were to add a nice heavy spring between the cable ends. you could use it to pull the slack but the spring will allow some slack in the cable.
Ideas are floating now.
There is a link in the Suspensions FAQ to a page containing a link to this thread, however it's not a direct link from the FAQ. I'll see what I can do.BTW is this setup in the tech library? If not, it would be another great thing for it or added to the TTB sticky.
