Technical An Argument for Dropped Spindles on Beam Axles

Thanks for bumping this. I was reminded of posts by @RodStRace and @pprather who mentioned the LM ('65-'69) Corvair LF wheel speedo cable drive setup:

Probably not ideal for an open wheel car (unless one can figure out a tidy cable route, or use angle adapters in some way), as @dirt car mentioned, but might save some headache when going from an electric to a mechanical speedo cable drive, at least in some situations.

 

what did the 4th one say about you?

 

She has a different outlook on things and still thinks I'm entertaining. God blessed that woman with the patience of Jobe. She certainly has reasons to throw in the Towel.

 

My Corvair front did not have the speedo cable hookup thing.

 

A lot of the stuff I post is pure what-if. I do it because it's interesting to me, an end in itself rather than a means of dealing with an immediate problem on the workbench. That's why "pick a different puzzle to solve" is so unsatisfactory an answer. I'm hoping the results of my puzzles become kind of catalogue of loose solutions which perhaps somebody finds useful.

But the weird-brain stuff is for real, and I reached almost 60 before I really understood how much of a struggle it's caused all my life. I got my diagnosis two years ago. It's fatigue issues and sensory issues and executive-function issues and more. So if you'd like to see some end results, imagine how much I'd like to see some end results!

(I did marry a good'un, though. She's been a help with all this.)

You and Pete are both missing that the forces are applied at the tyre contact patch, not at the centre of the wheel. Yes, I'd be introducing a bending moment in the spindle assembly between the kingpin bushes and the spindle, but the net moment at the kingpin bushings is actually reduced compared to stock. The force model consists of lateral forces at the upper kingpin bush, lower kingpin bush, and tyre contact patch. The nearer the kingpin to the ground, the shorter the moment arm.

There's an idea. But it'd probably involve 3D-printing a pinion, in which case you might as well 3D-print the rest of the parts too.

 

Kingpin forces are weight down and tire movement over surface up multiplied by distance from kingpin centerline and spindle, plus twist of decel from brakes acting on tire contact (amplified) plus twist of steering of spindle using the kingpin axis (amplified). The distance from KP centerline to spindle is additional leverage acting on the KP bushings in each case. Lowering the KP shortens this for the first and second as you say, provided the spindle can handle the increased load. The third should be covered by this same strength, but will add additional twist force to the KP bushings since it's not centered within it's upper and lower positions. At least, that's how it plays in my head.
I get the 'what if' thoughts, we all have them to some extent. But I am amused by the wild out there discussions you start. You want to do it different than what has been done before, but still remain in most of them to a traditional look, feel, style or mechanics. The analogy that comes to mind is traditional music with new new notes or time signatures.
I respond to your posts not to sway you away from the changes, but to explain why it's not been done that way before and interact. I hope you don't take it as that's stupid or wrong, but to explain why it seems not to have been done before. Devil's advocate, not naysayer.

In common parlance, the phrase "playing devil's advocate" describes a situation where someone, given a certain point of view, takes a position they do not necessarily agree with (or simply an alternative position from the accepted norm), for the sake of debate or to explore the thought further using valid reasoning that both disagrees with the subject at hand and proves their own point valid. Despite being medieval in origin, this idiomatic expression is one of the most popular present-day English idioms used to express the concept of arguing against something without actually being committed to the contrary view. Playing devil's advocate is considered a form of the Socratic method.

 

Ned; not picking on ya for sure. At 77 years young and growing up with what today is A.D.H.D. as well as Dyslexic the Teachers categorized as unteachable. The kids my age were mercy less even before the term Bullys was used. Thank God I was a lot tougher than the most of them. I have learned to just do it my way and not worry about others. It really helped when I decided I didn't need instructions, just figure it out on my own and move on. The last 40 years have been smooth sailing. Now if I can get a couple more of my unfinished projects done (much like you) before my ticket gets punched the Journey will have been a Good One.
