Relationship between camber link length and angle?

[Monkeysmate]

Can any one either explain or point me to a good (and simple) explanation of the relationship between camber link length and angle?
I short of understand the angle, but am somewhat confused by the affect of the length...
Anyone able to help please? Ta.

Very briefly; longer link means more roll which means slower change of direction and for instance on the rear slower for the rear to snap away but still generates rotation due to the shift in weight. Shorter link rolls less, so again as an example on the rear it will make the car change direction quicker.

Thanks chaps.
So then am I right in assuming that the angle of the camber link changes the amount by which the camber changes under shock compression?

Ok. I'm getting there...
I understand the image below, but can any one please tell me what happens to the roll centre if the upper link effectively is angled upwards compared to the lower arm, and hence the two red lines never intersect?



And, does having a longer upper camber link have the same effect as putting washers under the inner ball connection? i.e. raising the roll centre = less roll?

One of the best things to do is to go to your local track and try things on the car..

Just guessing but if you raise the inner camber link mount until it makes the two lines parallel then they intersect at infinity(or not at all) and your roll centre is at track level.

If you raise it still further then the two lines will intersect on the other side and your roll centre will be below track level.

Neither of these sounds good.

In addition, I think that it would make the tyres lean out a lot! If they are a rounded profile then that probably won't have much effect but if they are a flat profile then you would probably run out of tread.
