Ever seen the rear suspension of Dave Eulbergs Goliath. It's similar to your diagram, and it works pretty good.

doood u spill soe gud eye kant b leev et :D :D


not a bad idea (well yea it is) but here's the deal...the spring mounted to the frame is required to twist in order to allow the "shackle" to let the botom spring travel.....now if the rear end was linked them you could have a shackle at both ends of the normal springs and make the frame mounted spring pivot on it's center pin region so when up travel happens there is no awkward rear wheel positioning or bind on the links.

You COULD do that or just put coils or something on and be done w/ it :D

long live cardboard engineering....

I've seen something alot like that in Fourwheeler Mag a couple of years ago. I don't think it had the 2 regular leaf springs, but I can't remember how it was set up. Maybe just a 4 link with the bigass leaf springs going side to side. They were bigass leafsprings too.

hmmm good points guys dam and I thought I came up with somthing new


way to be origanul Alexis:shaking:

That is pertty close design to the suspensions on Triumps. They use locating bars for the rear axle and a leaf that goes from drum to drum. The axle is an independent with u joints in the center of the axle shafts. I guess it works fine.

Search for a yellow buggy called "Twister" on the net. he has something similar and god dayum does it live up to it's name:eek: :eek: :eek: :eek:

Isnt that just a sideways goofy leaf? Should work. How would you mount the shocks? How many? Looks like it might need some serious dampening!

a friend of mine who knows the twister guy said he changed the suspension to something else quite a while back.

I don't see where the springs on the frame will do much without a shackle on them. They will flex to the point of bind and quit.

If it's just the long spring from side to side then how do you control body roll:confused:

what the hell are you talking about? seriously you lost me here. Are you trying to say that the Main spring needs something similar to a regular shackle that pivots front to back, unlike this setup that doesnt acomidate the expansion of the leafs because the upper mount of the shackle goes perpindicular to the axle.

Both springs lower and upper when compressed will lengthen right? Well the way it is right now, the lowers look to have a shacke. The tops need to spread out and have no way to do that from the drawing. So they would bind on compression. Right?

I got 1/2 done with my spring outboarding project last night. :D

Throw some 8" blocks in there and she'll be cherry. :rolleyes:

What was the reason for using 3 leaf springs instead of something simple/light like coils?

Ok what if you put the axel springs over the "other spring" so it pulled under compresion

have you ever looked at a ford model a or t?

they ran that same set up.

i think this is a very old idea and it has been thrown away with all the junk!:flipoff2:

thats is an old idea, we as wheelers will have a hard time thinking of 'new' suspensions from all the stuff done in the early days.
the biggest problem i see is unstable roll, otherwise its the same effect as buggies.

That lateral spring was something I was planning on doing quite some time back, but after really thinking about it, I finally figured it was idiotic to do. I say this because there is NO lateral control at all. The rig will flop all over the place, but travel like crazy. The older Corvettes had this suspension setup, as did the early Fords. I say forget it and go with a proven setup, but that is just my opinion.

look at the pics on more time. he's not even close to an old T suspension. were talking 3 springs not 1.It seems like it ought to work but if I were to build it Iwould use a thick monoleaf that would sit resting on the frame at rest. the third leaf would really only help with droop. if you ran a spring in the center that had any ac at rest you would get bind because as it flattened the springs would want to seperate. then again youmight have the same problem with droop as well. by the way nice drawings:D
