Abstract
A vehicle suspension bump steer measurement apparatus and method of measuring bump steer in a vehicle suspension for productive management of toe change throughout compression and rebound of a vehicle suspension.
Claims14
An apparatus, comprising:
- a flat plate mounted to a hub of a vehicle suspension;
- a linear actuator positionable to engage said vehicle suspension,
- said linear actuator operable to move said vehicle suspension in successive incremented distances through a suspension stroke to obtain corresponding data points at each of said incremented distances, wherein said linear actuator has an accuracy over a suspension stroke of about two inches (about 50.8 mm) of about 0.015 inch (about 0.381 mm);
- a first linear potentiometer positionable to contact said flat plate mounted to said hub along a flat plate first vertical margin during movement of said vehicle suspension through said suspension stroke;
- and
- a second linear potentiometer positionable to contact said flat plate mounted to said vehicle hub along a flat plate second vertical margin during movement of said vehicle suspension through said suspension stroke.

An apparatus, comprising:
- a processor communicatively coupled to a non-transitory computer readable medium containing a program code, including:
- a linear actuator driver operable to drive a linear actuator to move a vehicle suspension through a suspension stroke;
- a first linear potentiometer data recorder operable to record first linear potentiometer data generated by a first linear potentiometer in contact with a first vertical margin of a flat plate mounted to a hub of said vehicle during movement of said vehicle suspension through said suspension stroke, said first linear potentiometer data varies based on movement of said plate first vertical margin around a hub vertical axis;
- a second linear potentiometer data recorder operable to record second linear potentiometer data generated by a second linear potentiometer in contact with a second vertical margin of said flat plate mounted to said hub of said vehicle during movement of said vehicle suspension through said suspension stroke, said second linear potentiometer data varies based on movement of said plate second vertical margin around said hub vertical axis;
- and
- a linear potentiometer data comparator operable to compare said first linear potentiometer data to said second linear potentiometer data during movement of said vehicle suspension through said suspension stroke.
