Providing improved balance in comfort and handling and a reduction of NVH
Tenneco’s Monroe Ride Solutions business, a global supplier of leading-edge suspension systems and components for light vehicles, commercial trucks, off-road equipment, and other applications, has achieved a breakthrough in passive damper valve technology that delivers an enhanced balance of optimised driving comfort and highly responsive, precise handling performance
The new, proprietary Monroe DCx (Double Comfort eXperience) piston valve, available in double-tube Monroe OE Solutions dampers, enables vehicle manufacturers to reduce noise, vibration, and harshness (NVH) in their latest models.
The DCx valve features dual-stage bleed technology, providing efficient, more intuitive tuning to meet the comfort, handling, and NVH characteristics desired for each vehicle. The dual-stage bleed design ensures minimal damping forces at low piston rod velocities, improving isolation of high-frequency road textures and micro-vibrations that contribute to NVH. This feature is independently tunable in rebound and compression, ensuring optimal damping force control.
The DCx valve is also compatible with Monroe Ride Refine secondary valve systems, which offer an array of additional tuning capabilities.
John Kinnick, vice president and general manager, Monroe Ride Solutions, said, “Monroe DCx is the first series production valve system for passive dampers that enables light-vehicle OEMs to eliminate the compromise between comfort and performance while ensuring outstanding NVH reduction. Our global engineering team continues to advance the science of ride control to serve the needs of the world’s leading vehicle manufacturers and their customers.”
