Title:
APPARATUS FOR MEASURING WHEEL ALIGNMENT
Document Type and Number:
Japanese Patent JPH04177116
Kind Code:
A
Abstract:
PURPOSE:To carry out accurate measurement by providing a light emitting means to the peripheral surface of a wheel and providing a position sensor capable of measuring the two-dimensional position of the light emitting means to a displacement measuring apparatus to make it possible to measure the three-dimensional position of the rotary locus of the light emitting means. CONSTITUTION:Wheel mounting rollers 1, 2 are provided on a horizontal surface in a rotatable manner and light emitting means 8 are provided to the peripheral surfaces of wheels and at least position sensors 16, 17, 18 capable of measuring the two-dimensional positions of the light emitting means 8 are provided to wheel displacement measuring apparatuses 10, 11 in pairs to measure the three- dimensional positions of the rotary loci of the light emitting means 8. A computer 20 operates the three-dimensional coordinates thereof and, on the basis of the coordinates, a camber value and the total toe value of front and rear wheels 5, 6 are operated to be outputted to a display screen 21. By this method, data near to actual running can be accurately and rapidly obtained.
