Apparatus comprising active alignment sensors mounted on the steerable wheel of a vehicle to follow the plane of rotation of these wheels, cooperating passive alignment means positionable selectively on the non-steerable wheels and on the adjacent vehicle body in view of the active sensors, and associated electronic equipment assembled in a console and responsive to signals generated by the active sensors for displaying alignment characteristics important to achieve motion balance in the vehicle for proper rolling response of the wheels and directional attitude of the vehicle body with steering wheel center-point position.

In vehicle wheel and wheel to body alignment diagnosing apparatus for a vehicle having an elongated body supported by first and second sets of wheels spaced longitudinally relative to the vehicle body and having alignment positions related selectively to wheel center line, body center line, and wheel thrust line references, wheel position sensing means carried by each of a first set of the vehicle wheels in position to represent the plane of wheel rotation, said sensing means having first photosensitive means positioned to face transversely between said first set of wheels, second photosensitive means positioned to face longitudinally toward said second set of wheels, and radiant energy projectors in position to direct separate radiant energy beams sweeping across paths generally perpendicular to and generally parallel with the plane of rotation of said first set of wheels such that the sweep of the perpendicular beams scan the positions of said first photosensitive means on said first wheel set, and the sweep of the beams parallel with the plane of rotation of said first set of wheels scans toward the positions of said second set of wheels; the improvement which comprises radiant energy reflective means adapted to be detachably carried by each of the second set of wheels, said detachable means including a mirror located to be substantially perpendicular to the plane of wheel rotation, means movable selectively to uncover and cover said mirror, and retro-reflector means selectively positionable on the vehicle body adjacent said second set of wheels and on said movable element, said radiant energy reflective means being scanned by the sweep of said radiant energy beams directed generally parallel with the plane of rotation of said first set of wheels; and signal generating means responsive to the scanning by said perpendicularly directed radiant energy beams of said first photosensitive means and the scanning of said radiant energy reflective means by said longitudinally directed radiant energy beams reflected back toward said second photosensitive means.
