kingpin inclination and camber change
(OP)
hi,
i am currently learning suspension geometry and i am really having a hard time understanding the relationship between kinpin inclination and camber change. from what i read, a positive kingpin inclination (upper balljoint closer to the center line of the car) will cause a positive camber change upon steering of the wheels and vice versa.
i am really having a hard time visualizing this because if the kingpin axis is positive wouldnt that increase negative camber upon steering of the wheels?. i have tried modeling an SLA suspension with wooden sticks but with no luck because i cant get an accurate measurement. is there a simple program i can use to simulate this? or am i completely misunderstanding this relationship?
thanks in advance

As far as your question is concerned, the suspension should be left out of the picture. The ball joints are simply two points representing a single line, just like a king pin. This should be very easy to model.
Once you get that visualized, you can move one point back or forward and see the effects of castor.

Blame the SAE!

that visualization helped alot and yes blame SAE for the confusion lol.
thanks again
