Introduction: Knex Buggy Independent Suspension and Steering

knex buggy with independent suspension and Ackermann steering. i can adjust it to have negative camber too.
*based on CRAZYCREATOR187 (ningana000 before) 's  buggy - https://www.instructables.com/id/knex-buggy-with-independent-suspension/ - .so because of him i had the spark to rebuild suspension+steering, i really liked those suspensions,hehe.
anyway,the instructable should be here soon if i manage to rebuild it and improve it, wohoo

how wide is the front end of it? meaning the front wheels including the suspension

author
danymw (author)speedbump142012-03-10

slightly narrower than the back end, but i can't tell much because i don't have it anymore.
aproximately 3 yellow rods put head to head

that we me on a friends account thanks i might make it do you think i could hook a motor to the steering and make it a rc knex car i have a drive system but i need a suspension and steering for the front and the back doesn't have suspension but i didn't want it to

i already build a full suspension rc car, but it breaks very fast and goes very slow.
it broke and i removed the suspension, it could go very fast for a knex car.
i have a compact one now but it doesn't go well enough

i am talking an rc car out of only knex parts and my car does so it is a rock crawler so it has a lot of torque. but would the suspension hold up to crawling not jump

author
danymw (author)chevy622012-03-12

if you can build it right
a knex rock crawler should be easier than what i tried ( put suspension and rear wheel drive on my buggy)

author
chevy62 (author)danymw2012-03-12

see i put a sold axle on the back but i want the front to give when i run something over so the back gets traction at all times. and do you have video or anything on your knex rc car.

author
danymw (author)chevy622012-03-12

i don't have any, but it wouldn't help anyway.
you either neet 2 motors, one on each axle, or make a gear box on the middle of the chassis and connect both.
you got pics of yours? i could help better

This is the steering set up i have now but i want to put your suspension and steering on it.

you can but it will be kinda big. try to make it less wider, it should work because i build it to be very strong, it was actually the model that i would have made rc after.

This is the back/gearing area. I design the car around the big gear i got from the Ferris wheel. and it has a lot of torque and i want to rock crawl with suspension on the front so when i am going up something the front gives little so the back gets traction at all times to the back wheels don't slip.

oh i get it now
but sadly it's almost impossible to make a front wheel drive with knex, unless we get special parts like in lego (shafts) or your car is really big. (this is why i never posted a knex full suspension rc)
that doesn't mean there aren't any solutions :) ,i don't know any yet

author
chevy62 (author)danymw2012-03-12

no, i am leaving it rear wheel drive for now but i want steering and suspension on the front and i will try to make it four wheel drive. but no i am leaving to rear wheel drive for now maybe we need to talk and find a four wheel drive suspension and steering desgin do you have skype.

author
danymw (author)chevy622012-03-12

i don't have much time now
i'll get back to cars as soon as i can and i'll try again four wheel drive.

author
danymw (author)danymw2012-03-17

sooo chevy made me do this: it's based on the buggy ^ , the rear is completely different but has a motor and suspension, it's fully rc but i can't test it because my (big yellow ) batteries are dead, for now.

nice you should make a slide show on it.

author
chevy62 (author)danymw2012-03-12

do you think your version would work well on it?

author
danymw (author)chevy622012-03-12

the best thing to do with knex is to try, modify, try again, if it doesn't work, you need another model or another mechanism (supposing you have enough parts)
it takes some time to build something, i think 3 days to make this buggy

author
chevy62 (author)danymw2012-03-12

i have plenty of parts but i am going to put a motor to your suspension and steering so it is more rc besides the fact there is a wire coming out of the car to control the steering but it was supose to be a all knex rc car and i can't find cyber knex

author
jmoore11 (author)2011-08-17

The front suspension doesn't look like it can take much abuse. Can you drop it from a foot in the air and have everything stay together?

author
danymw (author)jmoore112011-08-17

It's meant to be as strong as possible, because I wanted to attach RC motors to it.
I should be fine and hold together.
Now I have a knex car build for high speed RC. It doesn't have suspension but I need to find smaller RC parts and build a new one. I haven't found any way of making true real suspension RWD. Front suspension steering is too weak on knex to work good enough for RC. I need more development... and help //

author
jmoore11 (author)danymw2011-08-31

You need axles going through 2 or more connecters for it to be strong enough. I towed my car behind a bike and the wheels were fine it was just the linkages that were breaking. Good luck and be sure to post a video when your done! :)

author
danymw (author)jmoore112011-09-03

The big part was the back of a car, but it gets too big and starts braking. Suspension with RWD works but it's so hard to build properly and compact with knex TT.
Also by accident I found that a well cut white connector is fully usable with CVD shafts from nitro RC cars. I need a clutch, my motor is too powerfull...

That's a really nice car, sir. I like it.

What is that Ackermann steering actually?

author
danymw (author)TigerNod2011-06-14

An Ackermann steering is needed for precision.
I have a knex very fast RC, the Ackermann steering is critical, removing it causes major instability in steering.
I won't post it because...I used scrap RC parts that are somewhat custom so...

author
TigerNod (author)danymw2011-06-16

Yes, that is understandable.

coreyt (author)2009-07-24

now all thats needed is for someone to make a remotecontrol one

author
danymw (author)coreyt2009-07-25

i'm working on it,but i have a huge problem,well not that big,but still : engine,how to connect to the wheels? i tryed 3 ways,it's definitely not easy, i need some metal parts,or it will brake before catching speed. it's about keeping the suspension,otherwise it's easy

author
Acepilot42 (author)danymw2010-03-16

guess what guess what guess what!!!!!!!!!!! i made a slideshow and it shows a buggy i made with suspension and rear wheel drive!!!!! (shocks on the rear wheels too)!!!!!!!!!!!

author
coreyt (author)danymw2009-07-25

hmmmmmmm look at some different parts from rc cars and try and recreate them

author
danymw (author)coreyt2009-08-21

it's almost finished,beta stage. i made some sort of axel,i'll post it today, using ruber bands,which are a bad choise,but the only one.there is no motor that will power the car without breaking it...

author
danymw (author)danymw2009-09-22

pfff,i have to rebuild it from junk,using my own photos,lol

author
ferrari484 (author)danymw2009-08-20

If you want to make somekind of axle just forget it. You can't make sometihng like that so dam small out of knex. So i think you need to go for a other solution. Easy to say hard to do.
