Reyco Granning is introducing the next-generation IFS suspension family branded ComfortMaster. The first two platform variants will be based on 17,000 lb. GAWR and 20,000 lb. GAWR systems available for shipment Nov. 26, 2018. Additional capacities are in development and new configurations will follow, according to an announcement.
ComfortMaster is the latest generation IFS and will be the direct replacement for the IFS17S3, IFS18S3 and IFS20S3 product families. After a brief overlap period, these existing transit bus and motorhome IFS products will be phased out to make way for production of the new ComfortMaster series.
The system comes as a complete module without any loose parts. It includes sub-frame/cradle, power steering gear, steering linkage and all components to make it a unitized bolt-in system.
ComfortMaster uses nitrogen charged and sealed McPherson-style strut architecture. The nitrogen strut integrates the functions of: spring, shock absorber, king-pin and upper control arm into one component making the construction light-weight and efficient.
“The tidy packaging of the strut affords the highest possible wheel-cut angle allowed by today’s tire manufacturers — at a true 60-degrees vehicle maneuverability is simply unprecedented,” says John Stuart, president.
Reyco Granning completed subjective and instrumented performance evaluation comparing the ComfortMaster to both legacy Reyco Granning products and the leading competitor product. The on-vehicle evaluation clearly demonstrated a best-in-class ride and handling performance. For example, on a key handling metric the lane change lateral acceleration was improved by 29 percent. On a key ride metric, the vertical acceleration was improved by 32 percent, according to the company.
“With some iterative tuning we were able to achieve the Holy Grail, improving handling without compromising ride,” says Raoul Steenekamp, vice president, engineering.
