Roller drive-type compound vehicle wheel alignment tester

摘要

A roller drive-type compound wheel alignment tester for simultaneous measurement of toe-in and camber angles of vehicle wheels having detection rollers adapted to rotate in contact with sides of the wheels, said tester comprising a pair of wheel alignment units each of which includes toe-in detection rollers and camber detection rollers supported on a cross-shaped support member with the projection of the axes of said toe-in detection rollers intersecting the projection of the axes of said camber detection rollers and with said projections of the axes of the toe-in and camber detection rollers intersecting the axis of one vehicle wheel, a horizontally movable frame supporting said detection roller support member for movement toward and away from said vehicle wheel together therewith so as to bring said detection rollers into contact with said wheel and separate the rollers from the wheel, means for indicating inclination of said roller support member with respect to said horizontally movable frame, and means for indicating horizontal rotation angle of said roller support member with respect to the horizontally movable frame.
