General Information And Definitions
Toe-difference angle
a Toe-difference angle
D Centre point of operating circle
The toe-difference angle is the angle adjustment of the inner cornering wheel relative to the outer cornering wheel when negotiating a curve. Steering is
designed in such a way that angular position of wheels changes as steering lock progresses.
A correctly adjusted toe-difference angle produces equal values for left and right lock and consideration of factory tolerances.
Toe-difference angle provides information on corresponding operation of steering trapezoid for left or right steering lock from centre position.
Camber
Inclination of the wheel from perpendicular.
Toe
Reduction in distance of front of front wheels to rear of front wheels. Toe prevents wheels from running apart while driving and consequently wheel
shimmy and grinding, excessive tire wear, excessive loads on steering linkage and joints as well as hard steering of vehicle. Measurement is performed in
"straight-ahead mode"
