Product Advantages
High-efficiency torsional vibration attenuation, protecting core components
Adopting silicone oil medium, the attenuation efficiency of crankshaft torsional vibration reaches more than 70%, which reduces the fatigue wear of crankshaft, bearing and other components and extends the B10 service life of the crankshaft (matching the 1.8 million km design standard of WP12 engine).
It suppresses the risk of resonance and avoids serious faults such as crankshaft fracture caused by torsional vibration, and is especially suitable for the high-torque working condition of WP12 (maximum 2200N·m).
Stable and reliable, adaptable to harsh working conditions
Equipped with a metal shell and high-precision sealing structure, it is resistant to high temperature and aging, prevents silicone oil leakage, and adapts to the working environment of -40℃~120℃ in the engine compartment.
The dynamic balance accuracy reaches G2.5 grade, with low vibration during high-speed operation, which improves the stability of the pulley and accessory drive system.
Improved NVH perforce and fuel economy
It effectively reduces the vibration and noise of the whole vehicle, optimizes driving comfort, and matches the WP12 design goal of "low noise and low vibration".
It reduces the power loss caused by torsional vibration, cuts fuel consumption by 5%-8%, and improves operational economy.
