the arguments about ferrari's front pull rods have been going on for so long, that i decided to do my own analysis on the subject...you'll be surprised
below are the angles of the top and lower wishbones (yellow) and of the pull rod (red) of the front suspension on the F2012:
below, i gave the suspension 5 degrees of travel and the measured the length change on the pull rod...there was a +5% change...so the pull rod would be pulled at about 5% of its length...and if we assume that its length is 1 unit the extension would be 0.05 units....
now..when i come to last years suspension, the suspension on the 150 Italia..here are the angles again:
then i also gave the suspension on the Italia 5 degrees of travel and measured the length change of the pushrod....and there was only 3% decrease in its length (it should decrease because it is getting pushed inside) ...BUT....the pushrod is 36% longer so if we consider the pull rod as 1 unit of length as above...the length of the pushrod is 1.36 units....despite it being longer though the length of the pushrod being pushed inside is only 0.04 units...
so based on my results not only do the pullrods function as they should..but they might even be functioning just a tiny little bit better..giving better damping assuming the rockers are the same...so what i found is what Scarbs said from the beginning...it is not the angle of the push/pull rod compared to the horizontal that matters but the angle compared to the wishbones... in addition there is also the aerodynamic gain that Fry has been saying the pullrods give...
i know that the matter is not as simple as i made it...but my results are interesting none the less...is that right X??
