Instrument for measuring angles and for determining vehicle wheel alignment characteristics

摘要

An instrument for measuring angles between relatively movable references, and for use in determining vehicle wheel alignment characteristics. The instrument for measuring angles embodies transducer means having magnetic torque characteristics for sensitivity and simplicity of construction of the mechanical elements used to energize electrical circuit means for driving display means calibrated to read representative values such as angular relationships which can be translated into useful information such as vehicle wheel toe, for example.
