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 - http://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

Mar 10, 2012. 12:34 PMdanymw (author) says:

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

Mar 12, 2012. 6:28 AMdanymw (author) says:

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

Mar 12, 2012. 6:30 AMchevy62 says:

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

Mar 12, 2012. 6:34 AMdanymw (author) says:

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)

Mar 12, 2012. 6:37 AMchevy62 says:

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.

Mar 12, 2012. 6:40 AMdanymw (author) says:

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

Mar 12, 2012. 6:50 AMchevy62 says:

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

Mar 12, 2012. 6:54 AMdanymw (author) says:

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.

Mar 12, 2012. 7:06 AMchevy62 says:

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.

Mar 12, 2012. 7:14 AMdanymw (author) says:

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

Mar 12, 2012. 7:16 AMchevy62 says:

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.

Mar 12, 2012. 7:37 AMdanymw (author) says:

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.

Mar 17, 2012. 10:39 AMdanymw (author) says:

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.

this

Mar 19, 2012. 6:10 AMchevy62 says:

nice you should make a slide show on it.

Mar 12, 2012. 6:55 AMchevy62 says:

do you think your version would work well on it?

Mar 12, 2012. 7:02 AMdanymw (author) says:

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

Mar 12, 2012. 7:13 AMchevy62 says:

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

Aug 17, 2011. 9:08 AMjmoore11 says:

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?

Aug 17, 2011. 9:17 AMdanymw (author) says:

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 //

Aug 31, 2011. 1:33 PMjmoore11 says:

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! :)

Sep 3, 2011. 3:06 AMdanymw (author) says:

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...

Jun 14, 2011. 7:20 AMTigerNod says:

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

What is that Ackermann steering actually?

Jun 14, 2011. 10:02 AMdanymw (author) says:

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...

Jun 16, 2011. 1:29 AMTigerNod says:

Yes, that is understandable.

May 11, 2011. 4:42 AMdanymw (author) says:

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

Jul 25, 2009. 1:08 PMdanymw (author) says:

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

Mar 16, 2010. 1:25 PMAcepilot42 says:

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)!!!!!!!!!!!

Aug 20, 2009. 2:23 PMferrari484 says:

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.

Jul 25, 2009. 6:59 PMcoreyt says:

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

Aug 21, 2009. 2:42 AMdanymw (author) says:

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...

Sep 22, 2009. 8:05 AMdanymw (author) says:

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

Feb 4, 2010. 7:16 PMAcepilot42 says:

i made a four wheel drive truck with an automatic transmission, four wheel drive and four wheel indipendent suspension.
