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
--- 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.
