making it look period somehow you know when you reverse the eye on a spring, do the spring people simply turn the spring around - if you like flip it and re arch in the other way
I've traced the triangulated 4-link to 1961, when Oldsmobile used it. Visually, though, and the way it is commonly done, it seems to me very much the language of '50s circuit racing ch***is tech.
Not a '35 to '40 but a '32 that I'm building. I'm using a triangulated four bar and a '40 leaf spring on a 9". Before I installed the spring and after setting the pinion angle I raised and lowered the rear axle checking for any change in the pinion angle there was no deviation. If the four bar is installed correctly there is no variation in the angle. There will be no side loading on the shackle bushings. You should be able to attain the same results.
I did the triangulated rear 4 bar under a deuce sedan with 40 spring back in the late 80's and drove it over 40,000 miles before a friend bought the sedan which he rebuilt with a new ch***is and put the old sedan ch***is under a 29 roadster body which he drove for many miles.
Not your years, but I built my roadster back in the 80’s with triangulated four bar and a Model A transverse spring. Worked and rode great, and is still on the road with new owner in NH.
what I kind of meant I think was.... using original radius rods hiding on the lower arms and hiding the fatter end at the axle in the link somehow maybe going so far as to do some king of rubber ball in a spherical cap or something like that i dunno
I can appreciate the vison of money well spent almost as much as parts used up. In my case the vision was to make a roller as quickly as possible, spending very little cash and using what was extra in parts. I'm not sure if this is along the lines of what was being asked, but it goes to show what was made to work with the spares I had around.
Like this style? (not my frame, picture from another post). There's a bunch of posts on here, some people run top bars to the end (either heim or tie rod), some used an original front wishbone section with the ball and made the rear a wishbone and others used an off road "johnny joint". https://www.jalopyjournal.com/forum/threads/rear-radius-rods.659939/ https://www.jalopyjournal.com/forum/threads/the-modified-gets-an-update.654440/ https://www.jalopyjournal.com/forum/threads/rear-suspension-ladder-bar-question.1083237/
This is a good read........ https://www.motortrend.com/how-to/1...ible to reverse,sag in relatively short order.
Yeah man, it is. Could you please ask your question again, I am confused. You asked for triangulated bars, with a transverse spring. You were shown some excellent examples of that, but you sort of indicated that isn't what you mean. You didn't actually say "thanks, but that is not what I meant." Then you mentioned original radius rods and a totally unclear application. Now guys are showing ladder bar setups. Is that what you mean? There is nothing unusal about various versions of converging ladder bars and a transverse spring. Signed, Confused.
Sorry, should have stated it's not mine, I just pulled it off a post here for a visual........mine's waaay lamer.
Combining the front pivots of the ladder bars into a single point certainly is the "pure" way to do it. "Johnny joint" was my own first reaction looking at that pic. That would be basically the setup on the transaxle Alfa Romeo Alfettas etc. of the '70s and '80s, which handled very well indeed with the lateral location controlled by a Watts linkage. That brings up another point: a ladder bar setup like this needs a lateral locating device, in addition.
You mean lateral location? I don't see anything in the pics in Post #8. The two bushes on top of the rearend seem to have been intended for a triangulated 4-link, and apparently not used (which raises the question, why not go for a triangulated 4-link, then?) But in theory, the possibilities are endless: Panhard bar, Watts linkage, WOBlink, Mumford linkage, and a few more. A Mumford can be inverted if you want to play with high roll centres — not to be undertaken rashly. And the spring shackles can perform a lateral-locating function, though not at the angle shown in Post #8. It's a lot more complex than is seems: I tried to explain it here.
