Abstract: Due to the large cumulative error of parts and components, after the bus vehicle production is completed, the propulsion lines are out of tolerance, thus resulting in the vehicle driving deviation. In order to solve this problem, the cause analysis and accuracy improvement are carried out to provide references for the vehicle refinement design.
Key words: bus; propulsion line; four-wheel alignment; precision improvement
