GLOSSARY
Characteristic Angles
This term refers to all the angles that can be normally
measured on a wheel aligner (total front/rear toe,
left/right and front/rear half toe values, left/right
and front/rear camber, left/right caster, left/right
king-pin angle, and steering angle difference at 20°).
Equatorial plane
Ideal vertical plane that divides the wheel into
two equal parts.
Rotating platform
Base equipped with a disk on which the steered
wheels of a vehicle rest; it is used to reduce friction
between the wheel and the ground, in order to
favour the settling of the suspensions and cancel
the measuring errors during the steering.
It is highly important to keep the area between
the disk and the base clean at all times.
Oscillating footboard
The function is similar to that of the rotating plat-
form, but it is used for the non-steered wheels only.
Infrared rays (IR)
Electromagnetic waves that are invisible to the
naked eye.
Target
Measurement instruments that are applied to the
vehicle wheels to measure characteristic angles.
Clamp
Adapter between the wheel and the measuring
target.
