3 link with a Y upper

[BillyShope]

It would be the last problem after you locked up your wheels. After all - you don't have very much control over the vehicle with four wheel lockup. ;)

I was thinking here more of rear wheel lockup, which is just as undesirable. I'm certain the driver of the C-Type never locked up his rear wheels during the 24 hours of Le Mans.

I don't have any practical experience of it since I've never had any track time with a three link suspension, but I imagine that it rather has with unegual deflection in the axle. This would probably give different toe changes on right and left wheel, which will pull the car to the left.

Leave that defenseless little nit alone and stop picking at it! Yes, the asymmetry would leave the left side a bit weaker, but, again, the C-Type indicates deflections can be successfully controlled.

Where on that site can I find that info? I'm currently building a dedion-suspension for my Firebird and it would be interesting to see how much it should be offset.

You don't need asymmetry on a De Dion; driveshaft torque has no effect on rear wheel loading during forward acceleration.

I haven't found any info on how to find the offset in Milliken&Milliken.

I just checked and "asymmetry" is not mentioned in the index of Race Car Vehicle Dynamics. I used RCVD as a text when I was teaching and I don't recall a discussion of asymmetry, though I could be mistaken. [Yes, I am mistaken. It's found in the last paragraph of page 653. The last sentence says, "Under braking there would be a slight tendency to roll to the right, however." It should be understood that the preceding sentence was addressing the fact that, with full cancellation of the driveshaft torque, there would be NO body roll. In other words, the subject of the sentence is body roll and NOT a "pulling" of the car during braking.] I did supply a problem involving asymmetry which is a part of the student workbook which accompanies RCVD and the results of my derivation are there. It's also briefly mentioned in the Millikens' Chassis Design.
