Catia V5 Kinematic suspension assembly help 1

Hi all,

I am new to the community and am looking for some help with a kinematic assembly I am simulating.

I have created the assembly using damper travel and rack travel as my 2 commands. It all works fine and dandy so far. I then needed to output toe angle vs wheel travel so managed to create a formula and use simulation with commands and sensors to measure the angle of a line in the wheel (depicting toe angle) against the ZX plane. I managed to then export this data into excel, great!

The issue is that the wheel tilts through it's travel as I have used a fix together joint between the wheel, hub and upright. This is then scewing the results.

Is there a way to allow the wheel to rotate so the toe angle line stays parallel with the ground plane? I dont know whther this might be achieved using another formula or just clever use of joints?

Any help would be very much appreciated. I'm stumped!
 
If you add a picture or video of the system it will help us understand the problem.
