المزايا الأساسية للمنتج
1.Original factory mold opening, non-destructive direct installation
Strictly align with the original factory data of CNHTC, theinstallation bore diameters at both ends, and the centerdistance fully match the rear bracket of the cab. Nomodification is required, easy disassembly and assembly,and the repair shop offers higher maintenance efficiency.
2. Hydraulic damping + thickened roller spring dual vibration damping
The built-in high-pressure hydraulic damper isequipped with a thickened helical spring, providingdual cushioning for bumpy road impacts, filteringgravel roads and bumpy road vibrations, andreducing left-right swaying of the cab.
3. Fatigue corrosion resistance, long service life
Electrophoretic rust prevention treatment inside and outsidethe cylinder, high-temperature quenching of the roller spring,making it less prone to deformation and fracture. Thethickened rubber bushings at both ends arecompressive-resistant, aging-resistant, and stable and durableunder long-distance and heavy-load conditions.
4. Resolve various abnormal noise jitter faults in the cab.
Curb the vehicle’s cab vibration, abnormalnoise when passing speed bump orbits,long-distance cab resonance, and weaksprings, and enhance ride comfort.
5. Abundant stock, supporting domestic wholesaleand foreign trade exports. The Jinan warehousemaintains a large inventory, supplying auto repairshops and parts wholesalers nationwide; prodj己customs declaration documents and overseasheavy truck repair markets. One FOB delivery fromQingdao and Tianjin ports.
It is recommended to replace the fault scenario.
1. The cab is severely swaying, and there is an extreme sensation when passing over potholes.
2. The shock-absorbing spring has soft collapse, and the cab side is relatively low.
3. Shock absorber oil leakage, Damping failure,ffrequentabnoma noises fom vehicles
4. Cracking of the rubber bushings at both ends, Abnormal noise from falling off or metal impact
5. Major driving overhaul, Complete vehicle maintenance set replacement suspension parts
