1 (X): Left Wheel Roll Steer |
% (deg/100 deg) |
The left wheel steer angle change due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or: track = abs((right wheel center y) - (left wheel center y)) deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness) roll steer = (C(6,3) - C(6,9))*track/deltaz*100 |
2 (Y): Left Roll Caster |
% (deg/100 deg) |
The left caster angle change due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or: track = abs((right wheel center y) - (left wheel center y)) deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness) Orientation A: roll caster = (C(5,3)-C(5,9))*track/deltaz*100 Orientation B: roll caster = (-C(5,3)+C(5,9))*track/deltaz*100 |
3 (Z): Left Wheel Roll Camber |
% (deg/100 deg) |
The left wheel camber angle change due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or: track = abs((right wheel center y) - (left wheel center y)) deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness) Orientation A: roll camber = -(-C(4,3)+C(4,9))*track/deltaz*100 Orientation B: roll camber = (-C(4,3)+C(4,9))*track/deltaz*100 |
4 (RX): Right Wheel Roll Steer |
% (deg/100 deg) |
The right wheel steer angle change due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or: track = abs((right wheel center y) - (left wheel center y)) deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness) roll steer = (C(12,3) - C(12,9))*track/deltaz*100 |
5 (RY): Right Roll Caster |
% (deg/100 deg) |
The right caster angle change due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or: track = abs((right wheel center y) - (left wheel center y)) deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness) Orientation A: roll caster = -(C(11,3)-C(11,9))*track/deltaz*100 Orientation B: roll caster = (C(11,3)-C(11,9))*track/deltaz*100 |
6 (RZ): Right Wheel Roll Camber |
% (deg/100 deg) |
The right wheel camber angle change due to out-of-phase vertical deflections of the left and right tire patch points expressed in degrees of axle roll or: track = abs((right wheel center y) - (left wheel center y)) deltaz = C(3,3)-C(3,9)-C(9,3)+C(9,9)+2/(tire stiffness) Orientation A: roll camber = -(-C(10,3)+C(10,9))*track/deltaz*100 Orientation B: roll camber = (-C(10,3)+C(10,9))*track/deltaz*100 |
