Clarification on Camber
Clarification on Camber
(OP)
I drew up three different unequal length A-arm suspension on CAD and attempted to find out the differences and how each one of them gains camber. I write this post only because I wish to see if my observations were correct.
I'm guessing that the changing camber is based upon the ratio between upper and lower A-arms and how they affect the length of the swing arm.
I'm guessing, after having graphed it, that since the graph of swing arm vs. degrees of suspension travel turns out to be a hyperbola that the eccentricity of the hyperbola for a given suspension is a good judgement on how much camber a suspension will ultimately gain and how broad in a sense the camber peak will be.
I had to state from scratch on this one since my books are back in the states and I am currently overseas. Any help in setting me on the right path would be greatly appreciated

RE: Clarification on Camber
To be honest I can't really understand your terminology, I'm not sure that you can really describe a given camber curve as just a single figure, and I've not seen anyone attempt to do so before.
For a given lower arm length, assuming at design it starts parallel to the ground, then there are 4 unique properties of the upper arm to consider, all of which will affect the camber curve to some extent, so I would expect your results to need 4 numbers to quantify them. If you also want to change the lower arm then that adds another two parameters to the mix.

MarkEE,
I would also like to evaluate Racing by the numbers. Could you place it somewhere so it can be downloaded?
Thanks,

I have a Zip file 940 KB it is a dos based program. I can attach it to an e-mail or if you have any other suggestions?

MarkEE, I have no problem getting the file emailed to me. Here is a link to my address.

I tried accessing the above geocities link and received a this page is not viewable. Let me know and I'll send it.

therefore in order to see it we have to visit the geocities site directly.
The easiest way to do that is to right click on the red cross,look at properties, copy the address shown into 'open link' and bob's your uncle.
Nice diagram by the way, but there is a mistake in the third one down, the camber curve is inverted.
