Air Suspension Calibration Machine

This calibration machine detects and calibrates air suspension height to keep the vehicle body level, with automatic wheelbase adjustment based on vehicle model data. Tires are clamped pneumatically with a positioning error below 2 mm while the vehicle stays in normal contact with the ground, so ride height and attitude are unaffected. At least two photoelectric switches verify vehicle positioning, and a calibration frame measures the Z-direction wheel-arch height relative to the tire support surface with ±1 mm accuracy and ±0.2 mm repeatability.
