  • Four sensor system for wheel alignment
    Patent number: 6327785
    Abstract: A four sensor wheel aligner has a single omnidirectional angle sensor mounted on each of four vehicle support wheels. Each sensor is in optical communication with the other sensors. Data is produced from which toe, camber, caster and steering axis inclination angles are computed. No reference is made to vertical. Redundant data sets are produced which provide system reliability and error tracking features and maximum accuracy from available data sets. Frame distortion measurements are made to facilitate collision repair in coordination with wheel alignment.
    Type: Grant
    Filed: February 24, 2000
    Date of Patent: December 11, 2001
    Assignee: Snap-On Technologies, Inc.
