A well-designed suspension system can significantly enhance the fuel efficiency of a truck

Firstly, the adjustment and condition of the suspension system directly impact tire-ground contact. Inadequate stiffness or wear in suspension components such as springs and shock absorbers can lead to increased rolling resistance, necessitating more energy for propulsion and resulting in higher fuel consumption.

Secondly, an effective suspension system contributes to vehicle stability, particularly when encountering load variations or abnormal road conditions. Insufficient shock absorption or load stabilization may cause unnecessary wobbling or bumping, leading to additional drag and energy consumption while potentially damaging cargo.

Thirdly, a high-quality suspension system ensures consistent tire-ground contact throughout driving, promoting better fuel economy by preventing uneven pressure that would otherwise require extra power for tire rotation.

Lastly, during braking maneuvers, the suspension system aids in controlling body attitude to minimize nodding effects. Poor suspension performance increases long-term fuel consumption due to heightened braking force requirements from frequent acceleration and deceleration cycles. Therefore, maintaining a well-functioning suspension not only enhances driving comfort and safety but also indirectly saves fuel by reducing unnecessary drag and improving overall efficiency.
