Tenneco has expanded its Monroe OE Solutions portfolio of passive valving technologies with the introduction of an advanced, highly tuneable stroke-dependent damping (SDD) add-on valve. Named the Monroe RideRefine SDD, the valve works in conjunction with Monroe’s main valve technologies to deliver comfort and control characteristics.
Stroke-dependent damping enhances comfort by reducing damping levels during short strokes of the unit’s internal piston. A bypass directs oil into the RideRefine SDD valve, which provides separate, tuneable damping of small strokes for reduced noise, vibration and harshness (NVH). At the end of the short piston stroke, the damper’s main valve resumes normal operation.
The tuneability of the SDD valve enables vehicle manufacturers to select the ideal comfort profile for short piston strokes, for each of their vehicle models.
“The RideRefine SDD valve brings new levels of versatility, tuneability and comfort to passive damper performance,” said Romain Nollet, group vice president and general manager, Monroe Ride Solutions. “Stroke-dependent damping helps to ensure that the dampers effectively filter out minor road inputs on highways and other smooth roads, thus providing a feeling of luxury and plushness to the ride experience.”
