Introduction

JJF 1154-2014 "wheel alignment calibration norms" (hereinafter referred to as "the Rules") is four Locator school Accurate measurement specifications. Wheel alignment automotive manufacturing and maintenance business for detecting a vehicle wheel alignment parameters, and Compared with the design parameters to guide the user to adjust the wheel alignment parameters of the instrument. JJF 1071-2010 "National Calibration Specifications writing rules", JJF 1059.1-2012 "Measurement Uncertainty Evaluation and Expression "and JJF 1001-2011" common measurement terms and definitions of "together constitute the support base of the code revision The foundation of the series specifications. This specification is based on JT/T 505-2004 "wheel alignment" as the main reference standard edition JJF 1154-2006 Subject to revisions. Compared with JJF 1154-2006 "wheel alignment", in addition to editorial changes, the major technological change as follows. --- Increased 3D image four-wheel locator and online non-contact wheel alignment in the scope, as well as Corresponding schematic. --- The technical requirements for wheel alignment calibration device, calibration device simulation clearly defined and simulated axes Tread Distance requirements, and other requirements indication error. --- Increasing the toe angle single round in the calibration project, camber zero error and Kingpin Inclination indication error calibration. --- On a single round before toe angle, camber, caster (inner) angle measurement range, showing error and repeat Sex has been modified. --- Increasing the wheel alignment calibration method calibration apparatus in Appendix B. The previous versions of this specification published case. --- JJF 1154-2006. Wheel alignment calibration specification
