Lake Forest, Illinois.And December 1, 2021 /PRNewswire/ – Tenneco (NYSE: TEN) has expanded its portfolio of Monroe® RideRefine™ additional technologies for passive dampers include a new adjustable terminal stop technology that supports global automakers’ electrification and vehicle lightweight strategies.
The Monroe RideRefine Hydraulic Compression System (HCS) improves ride comfort and body control by enabling a better trade-off between ride height and damping with stroke pressure.
The RideRefine HCS sub-assembly is one of many add-on units that can be easily combined with standard Tenneco piston valves and twin-tube retarder assemblies.
The new Monroe RideRefine Hydraulic Compression System (HCS) improves ride comfort and body control by enabling a better trade-off between ride height and damping with stroke pressure. It significantly reduces the shock forces transmitted to the bodywork near the end of the damper’s crunch stroke. By controlling peak final stopping power, this technology helps manufacturers reduce the structural requirements for vehicles that typically carry heavier loads – including battery packs – and/or have limited ground clearance. It is also ideal for vehicles equipped with larger tires, such as Sport Utility (SUV) and Crossover models, which can generate higher final stopping loads.
The RideRefine HCS subunit is one of many add-on units that can be easily combined with standard Tenneco piston valves and twin-tube damper assemblies. Operating quickly and smoothly, the HCS dramatically reduces bottoming load and filters out the noise and harshness of high-impact road events that can occur when driving over pavements and potholes. Testing on a leading luxury SUV platform showed a lower load reduction of up to 30% compared to dampers without HCS.
This technology increases damping force within the “HCS zone” near the end of the compression stroke and allows damping force to be reduced near the middle of the stroke, improving overall ride comfort and refinement. The HCS area can be precisely tuned to the unique requirements of each vehicle model.
“RideRefine HCS builds on our heritage of innovation in passive suspension technology,” said Nick Underwood, vice president and general manager, Ride Control, Tenneco. “The introduction of HCS technology is timed to support our OEM customers’ emissions and electrification efforts, providing value through better ride quality and lighter structural requirements.
“This cost-effective, modular solution expands the performance capabilities of best-in-class passive dampers. Innovations like this extend our offerings to global platforms and allow our customers to improve performance and reduce complexity.”
In addition to the new HCS valve, the Monroe RideRefine range includes patented additional valves that use stroke-dependent damping (SDD) and frequency-dependent damping (RC1). These technologies provide more precise and capable riding dynamics.
