Table 5
Acceleration (m/s2) on both sides of cab suspension near 65 km/h.
| | Cab shock absorber | Front suspension body side | Front suspension frame side | Front suspension vibration isolation rate | Rear suspension body side | Rear suspension frame side | Rear suspension vibration isolation rate |
| | Original air spring | 3.05 | 1.78 | −4.68 dB | 2.05 | 3.11 | 3.62 dB | | Ex-brand 1, post-brand 2 | 1.39 | 2.37 | 4.63 dB | 1.29 | 2.01 | 3.85 dB | | Both are brand one | 1.96 | 3.30 | 4.53 dB | 1.61 | 2.55 | 3.99 dB |
