46,000 lb Raydan Rear Suspension

Suspension:	Raydan Airlink at 46,000lb rear GAWR
Suspension Ride Height:	13.5" from centerline of axle to bottom of frame
Rear Axle:	Meritor RT-50-160 with wide spread barpin brackets
Vocation:	Military on / offroad, sand, snow, rough asphalt road surface. NATO Compliant.

Design Criteria

• The standard 46k Raydan Airlink suspension comes in a ride height of 10.0" from the center of axle to the lower surface of the frame rail. To meet the 13.5" ride height that we needed Raydan developed equalizing beams with a 3.5" offset so that the rest of the standard parts could be used.
• The suspension component drawings were only available in 2D format so ProE 3D models were created and assembled using datum curve skeletons to allow articulation. The suspension could be studied throughout it's range of movement to determine necessary clearances for bumpstops, fenders and crossmembers.

Additional Information:

Steel full fenders were required to cover the rear suspension wheels with a minimum clearance of 2.0" during full suspension articulation. It was important to minimize this clearance to keep the fenders low enough to mount the paletized loading system that was eventually installed on this truck.

Final Documentation:

Full 3D model assemblies and articulation layouts were produced in addition to installation diagrams for all of the suspension related components.
