Lateral effects

[ttmott]

The PHB article is in the August 2006 issue, which I do have. Around 50k in either Word or pdf, and since Mr. Ortiz actually encourages reproduction for free use I believe that I can e-mail any number of copies out as long as I don't request payment. I'd prefer to send the pdf, though.

I modeled my 4-link on ProE showing the PH bar skewed in one model and parallel on the "y" axis in the second model. Then moved the suspension both up and down and simulated 4-inches of total differential side to side. There was virtually no change in hub positions between the two models. The only difference is the skewed bar added some stress to the 4-link bars at the side of the axle where the PH bar is attached when side load is applied (in my case, compression on a left hand turn and tension on a right hand turn). The load is obviously proportional to the angle of the bar. For very small angles the effect will probably not be adverse. For larger angles depending on the configuration of the 4-link one side of the chassis (where the PH bar is attached) may want to rise or drop. I'm back to making it parallel......
