Quarter- Eliptic, Composite, Mono Leaf Springs

[ag1234]

Front straight axle with about 400lbs, static corner weight. Urethane bushing at axle end, {compliance}. Spring is inverted for better rising-rate and ro[l-caster gain, as an upper, leading link. Question is, mounting diagonally, to handle lateral loads ? Not likely to exceed 1G lateral. Using metal lower leading link. Anti-roll bar may attach to ether link. Second design is "pickle fork", with roller bearing mounted on real side of axle,( slides up/down in slot).   Thoughts ? Thanks,  Art.

KISS?

I think I need a sketch... and some context: What car would you put this under?

First to JB., KISS, not helpful. Why bother ?
  To Curtis, thanks for answering.  No skill to upload sketch, but this is the Rover V16, all aluminum roadster, cept' f-glass body.
   Entire drive train is stress-mounted which makes 1/8" wall aluminum frame, workable. Since aluminum engine girdle direct receives
 . input load from quarted-eliptic monoleaf, loads are acceptable. About 1.5" squash and 2,5"dangle, travel , at wheel, should be
   enough( straight axle).
                                                             Thanks,  Art.

Front straight axle and leaf springs sounds like pre-war stuff, or a truck. The guys that make "cyclekarts" (HF predator motor, Honda 90 bike tires, homemade chassis...) are big into the pre-war examples for their half-size "replicas". The site is at least a decent repository of example cars/chassis/suspensions that aren't difficult to copy.

I did a composite transverse 1/4 leaf design with lower A-arm for an Auto Union Type C I spent a week deciding whether to build...

"Question is, mounting diagonally, to handle lateral loads ?"

Do you still plan to use a panhard rod, Art?

Straight axle street rod stuff is before my time.  Maybe something in here may help:

I enjoyed this little history lesson on straight axle street rods.

Chad and Carl, Thanks. No panhard bar, Maybe pickle fork/roller bearing(tunable roll center).
