SITRAK T7H SITRAK C7H Auman GTL Cab front and rear Air Spring Shock AbsorberWG1664440201
It is installed in the lower section behind the front grille, bridging the front chassis crossmember and the front cab suspension bracket; it is also located beneath the rear sleeper berth and inside the air deflector, directly connecting the main chassis side rail to the rear cab mounting bracket.
Product Features
1. Superior Shock Absorption and Vibration Damping: External air bellows absorb severe road impacts, while internal hydraulic dampers rapidly suppress residual vibrations, preventing excessive cab oscillation.
2. Automatic Vehicle Attitude Maintenance: Linked to a height control valve for inflation and deflation, the system automatically adjusts suspension height during braking, cornering, or varying load conditions to keep the cab level and stable.
3. Noise Reduction, Structural Protection, and Fatigue Mitigation: Effectively isolates high-frequency road noise and vibrations transmitted from the chassis, protecting sensitive onboard electronics and bodywork, while significantly reducing driver fatigue during long-haul journeys.
Common Faults and Inspection Methods
1. Air Bellows Cracking or Air Leaks: These typically occur at the base of the bellows' folds. Spray soapy water on the surface of the bellows to check for bubbles; air leaks can cause the cab to sag on one side and lead to frequent air compressor cycling.
2. Internal Shock Absorber Oil Leakage: Visible oil residue on the exterior of the damping cylinder indicates a failed oil seal. This results in a loss of damping function, causing the cab to experience continuous residual vibration and swaying when driving over rough roads.
3. Height Control Valve Malfunction: The inflation and deflation of the air bellows are regulated by the height control valve. If the cab tilts or fails to inflate, in addition to inspecting the bellows themselves, check the air lines and the four-circuit protection valve for blockages.
