Multi Link Suspension
Multi Link Suspension
(OP)
We are designing and fabricating a circle track race car to be run on dirt. It is going to be mid/rear engine and rear wheel drive, therefore requiring independent rear suspension. We've normally dealt with a live axle rear suspension with a 4 link design, so we don't know exactly how an independent rear suspension works. The basics aren't hard to understand, and we believe that it has several advantages over a live axle, since each wheel acts on its own, and not affecting the opposite wheel as it travels over bumps and such. What we need to know, is what creates traction on a multi link suspension as far as forward/side bite in the turns while on the throttle? Are there better designs than others? We are open to any and all ideas.
Thank you very much!
Thank you very much!

BUT I wouldn't say double wishbone is necessarily what you want. The most important thing with your car is to react the traction forces reliably, and a typical double wishbone struggles a bit there. You might be better off using a long trailing arm, and then whatever choice of lateral links take your fancy. Look at a Lotus Esprit for a simple, robust if not especially tunable example.
Does Mark Ortiz discuss IRS for circle racing at all?
Once you go to an IRS you'll probably want to soften off your wheel rates to take advantage of it.

RE: Multi Link Suspension
What I'm most confused about, is that in a dirt late model, the rear end is actually rotating, which makes it bite. On an independent suspension with a rear/mid engine, it doesn't have that. The only thing that rotates is the CV joints. That's why I was wondering if anitsquat geometry bites no matter what type of suspension it was.
