TENNECO UNVEILS ADVANCED HYDRAULIC REBOUND STOP SYSTEM FOR MONROE OE SOLUTIONS PASSIVE DAMPERS

Tenneco has unveiled an innovative, highly tunable hydraulic rebound stop (HRS) system that minimizes damper rebound topping energy and noise encountered in BEVs and other comparatively heavy passenger vehicles ensuring optimal energy absorption. The new system, Monroe^® Ride Refine Advanced HRS, also eliminates the need for chassis reinforcements commonly added to resist high-energy impacts. Now available in Monroe OE Solutions double-tube shock absorbers and struts, the system can also be custom-tuned to increase body control empowering OEMs to deliver outstanding ride comfort in all driving situations.

Engineered to provide high damping force and best-in-class noise performance, the Ride Refine™ Advanced HRS system features an innovative grooved and swaged pressure tube and high-resistance sealing ring that provide a virtually imperceptible, highly progressive transition to HRS activation. The system’s broad tuning curve is defined by the pressure tube swage length and bleeds on the side of the sealing ring. By eliminating a mechanical spring, Tenneco engineers also reduced damper weight and packaging requirements.



With the introduction of the new system, Tenneco now offers three highly effective, differentiated hydraulic stop technologies covering virtually all passenger vehicle use cases. Other Monroe designs include spring-equipped standard HRS and Performance HRS.
