Sensors detect actual trailer inclination and feed back to a control unit that automatically adjusts the suspension, eliminating manual leveling time.
Relocating damper pivot to vehicle body and adding lower arm bulge reduces sliding friction while maintaining road clearance.
A traction bar uses a pivoting shackle to limit axle rotation during acceleration.
Dual tolerance ranges in vehicle level control filter minor deviations to reduce air consumption while triggering rapid adjustments for large irregular changes.
A single shell spring link uses inwardly formed flanks to create a C-profile cross-section that increases structural rigidity.
Composite longitudinal link eliminates separate resilient bearings by integrating transverse rigidity and longitudinal flexibility, reducing device complexity.
