1 (X): Left Caster Angle

deg

The magnitude is the global side view angle between the left wheel kingpin axis and global vertical.  The sign is positive when the kingpin axis goes towards the front of the vehicle at the bottom and towards the rear of the vehicle at the top.  See Figure 3 (below).

2 (Y): Right Caster Angle

deg

The magnitude is the global side view angle between the right wheel kingpin axis and global vertical.  The sign is positive when the kingpin axis goes towards the front of the vehicle at the bottom and towards the rear of the vehicle at the top.  See Figure 3 (below).

3 (Z): Average Caster Angle

deg

The mean of components 1 and 2.

4 (RX): Left Kingpin Inclination Angle

deg

The magnitude is the global front view angle between the left wheel kingpin axis and global vertical.  The sign is positive when the kingpin axis goes outboard at the bottom and inboard at the top.  See Figure 4 (below).

5 (RY): Right Kingpin Inclination Angle

deg

The magnitude is the global front view angle between the right wheel kingpin axis and global vertical.  The sign is positive when the kingpin axis goes outboard at the bottom and inboard at the top.  See Figure 4 (below).

6 (RZ): Average Kingpin Inclination Angle

deg

The mean of components 4 and 5.
