Technical could use search phrase help

i'd like to read up on something so the inmates don't think i'm lazy when i ask the inevitable questions, but i cannot seem to get the right wordsmithing to stike internet gold.

to wit: what term could i use to learn how & why stock car front axles/ wheels have an extended hub? ideally, i would like a cut away drawing so i could understand the gubbins and even an explanation why such a hub would be required.

inquiring minds wanna know!

thanks

 

The load on the wheel bearings is centered by locating the outer bearing there.

 

yes; Turn Left! and they had a pony wheel to compensate the banked track (i think that was why)

the hub was larger diameter and stuck out quite a bit further than a standard nut w/ dustcap style from the Factory.

like these (for 1:25 scale) Ron Coon Resins | Hubs & Brakes - Circle Track Resin Parts

i'd just like to know why & how when i build something.

thanks,

sid

 

BINGO!!!!

thanks guys.

takes a village, huh?

i appreciate the help.

Floating? Ie like a 3/4 ton axle?

 

i have no idea what the means. is that why some trucks have really extended wheels in the frontz/ like the center of the wheel which has a lot of lug nuts and sticks out way farkin' past the tire sidewall?

i'm lost here guys ....

 

thanks.

 

search for "full floating hub"

 

and "Wide Five" hubs

@s.e.charles
also search "wheel offset" , "hub offset" , "kingpin inclination" , and "scrub radius" [also use Google images]

full floating hubs are rear end.


The hubs support weight, and the axles are only subjected to torque

 

from the last picture, and maybe a thing of the past which has been superseded by a better technology,
where does the component which would make this a "safety hub" be installed?

i think i know it keeps a broken axle shaft from flying out of the housing w/ wheel attached, but from pictures in the for sale section of the forum, i cannot quite figure out how the pieces bolt together.

and thanks for the search keywords. i'm gonna be all over this!

s.e.

 

oh; You're the guy with the "typewriter" page!

i've checked that out before & even saved the Cragar catalog for reference.

thanks for the search prod, too.

 

Full float has a separate hub mounted to the axle housing drivin by an axle shaft.
The main benefit is it has double the bearings of a simi float axle and you can continue cruising with a busted shaft.

 

and you can flat tow it after removing the axle shafts

On the front, it gives way larger wheel bearings, and is much stronger, than a normal front spindle.

 

Round track rides experience some crazy loads on the wheels, hubs and spindles
Plus banging into walls and other cars

 

The axle is bolted to the end of the hub.
Take the 8 (I’m familiar with) nuts off, slide the axle out, the hub and bearings stay put.
The outer has a nut to adjust for the load, then a “tang” is bent over on that nut so it won’t back off.
Now this is just my experience with stock stuff, no idea if what’s used in racing is the same.

 

they were also built with splines at the end of the axle, and a cover over the hub, so you could pull the axle and put the cover back on. This was mostly bigger truck stuff, though.

 

Just how detailed of an explanation do you want?
What you see on the successful left turn cars pictured has taken years of experimentation, trial and error, and gained knowledge. These days its nearly all done on a computer for the initial set up, but then always adjusted at the race track for any given day of racing.

Consider this. If you are driving your street car down the road at a speed above 30 mph, and decide to turn left at the next cross street a block away. How is your car going to respond if you make that 90 degree turn at your current speed?

Ever make one of those highway curves that are marked as a 30 mph turn at 45 mph? Ever try the 30 mph curve at 60 mph? What if that curve was 180 degrees instead of 90, or 45 degrees?

The left turn race car running on a 1/2 mile track covering that track in a 30 second lap (really slow these days, my hobby class dirt cars were doing 27 second laps in the early 1980s), averages 60 mph for that lap. The car makes (4) 90 degree turns with 4 straights between, or it makes (2) 180 degree corners and has 2 straights (or some combination of the two choices). The simple math is 2 curves and 2 straights. To average 60 mph, the car has to do 90 the entire length of both straights and maintain 30 through both U turns. Now put those numbers into that 30 mph curve on the highway. You are probably going to want all the help for the front suspension, and the brakes. you can get. If you are always turning left, the right front is going to take all the abuse.

 

before the gas crunch (1973 one, when gas soared to $1 @ gallon and we waited in line on odd/ even days for $3 worth) i used to go to Seekonk Speedway [maasachusetts] with as many guys as would fit in the car and watch "the races." the women in the stands were ruthless; shouting at their favorite - or hated - drivers. parts flying only made them happier. good times for a kid who had just gotten his drivers license.

 

that's a pretty good perspective for what the car's doing for a lap. i probably won't try that on the street though!

 

Whenever something is 'different' on a car, consider what was the reason.
If it's a race car, it's probably going to be weight, strength or rules. In this case, it's a visibly bigger part, so strength.
If it's a modified street car, it's for looks, performance or just to follow the other mods OR to stand out as different. They often use race car parts to emulate the look, even if it doesn't work as well as normal parts.

For search terms, try to describe what you are looking for in the fewest, most direct words. If you don't get results you want, add another word or two. Look over the results and if you get close, use the name of that result to search.
For example, there is a new post about Route 66. Try "Route 66" not "America's First Major Highway" If you want more info for a specific state, add that. If you want history, add that. If you want lodging, add that.
If you are using one of the search sites instead of the HAMB search, they will usually have Images results, which can help you find things or refine your search. Most have ways to modify the search and you can search for tutorials on these. For example here is one result for Google search.
https://ahrefs.com/blog/google-advanced-search-operators/
These can often drill down much better, but most people don't remember all of these unless it's your job all the time.
I will mention that the search engines are not providing results as well as they did a few years ago. The ads and the companies that pay to be near the top have diluted the returned results. Where once you got a good variety of sites that applied, you now get the same top sponsor repeated 2 to 3 times on the first page.

To your exact question, search for "circle track front hub". You will get sites selling. Try adding "history" to the search. You will get sites covering the history. Open a couple and see if they answer your question. If not, go back and search for "Circle track front suspension" then add "Design" or "Theory". You may get some heavy in-depth lessons, but learning a bit or a bunch more isn't a bad thing.

 

thanks Rod. good information arrows for my search quiver. the Google link is awesome.

i get trapped by my own thinking sometimes and forget to investigate unfamiliar territory. for example: search engines. i used Ask Jeeves for years and now DuckDuckGo, but forget if i change around i can
get completely different responses.

never know how much or little to use for the initial search. paint with a broad brush or put a point in it?
after 3 tries my a.d.d kicks in, and, much like the squirrel in the road, i'm off on another topic.

thanks again,

s.e.

 

You got it.
Aside from Google and Bing plus the ones you mentioned, I occasionally use
https://www.ecosia.org/
Jeeves used to be my go-to, but it was not helping years back and it fell off my radar.

Just searching for Great Search Engines gets results too!

embarrassingly i cannot find my post on the Ford Barn forum, but "yes" i have had this difficulty in things more traditional, too. i wanted to extend and extended "thanks" to the member that turned me on to this search phrase (?):

flathead V8-60 site:fordbarn.com

i haven't had the opportunity to try it with other forums or & subjects, but the key seems to be the word, colon, and then the forum you want to search.

so i guess here it would be: subject site: jalopyjournal.com

oh; hot diggity - works like a charm. give all the responses on the specific site with no fluff
