Wide angle vehicle wheel alignment system

摘要

The system includes beam emitters mounted on each supporting wheel for directing a beam toward the same side and one diagonally opposite wheel. Beam receivers mounted on each supporting wheel in known orietation receive the beam from one same side and one diagnally opposite wheel mounted beam emitter and provide angle output indicative of angle between the beam receiver mounting wheel and each received beam. Cross beam emitters are included mounted on each of two laterally opposed wheels, and cross beam receiver means is mounted on each of the two laterally opposed wheels in known orientation for receiving the cross beam from the laterally opposed wheels mounted cross beam emitter and for providing angle output indicative of angle between the wheels.
