CV axles articulation angles
Hi all, I'm an mechanical student in Baja SAE.
I want to choose 2 pairs of CV axles for the front and rear of my car for next year.
I read for a certain CV, it has an outboard angle minimum of 40° and an inboard Dual Offset Joint maximum angle of 30°. What does that mean exactly? I'm thinking outboard min angle means I can set the outboard angle to be greater than 40 degrees at all times (not sure about the maximum) and the inboard angle to be less than 30 degrees
Am I on the right track on this?
Thank you all.

You can use a greater outboard angle, but you can use a minor angle too. But you shouldn't use the maximum angle capacity of both.
In other words, i don't recommend you to reach the maximum angle capacity in operation.
I recommend you to sincronize the suspension pivots with your drive train design, focused in the cv joint mechanism (articulations and sliding shafts , without exceed the maximum angles). If you have the complete information of the cv joint configuration your job would be more easier.
If you ignore the movements of the suspension system, you may add undesirable axial forces against the drive train (depend of your train design), or an undesirable cv joint discoupling.
Maintain the axles aligned at the rear or front tracks, like Formula SAE's. it's not a must, but is better.
I hope that my advices would be useful to you. You have to sign in the Baja & Formula SAE forums to ask more questions related.
Baja SAE is fun as hell!
