Vehicle wheel turning angle gauge

摘要

A vehicle wheel turning angle gauge having a base to support a wheel engaging turnable plate which supports an optical encoder device mounted in non-rotary position so an operating shaft can engage and turn with the turnable plate to generate signals of the degree of turn and the direction of that turn. The base provides a structure for limiting the maximum displacement of the turnable plate without restricting its direction of motion so it will accommodate the range of vehicle wheel movement as required for alignment purposes.
