SAF-Holland said it is releasing the Neway ADZ series drive axle air-ride suspension for vocational trucks and tractors. The new suspension has been engineered for vocational applications including construction, mixers, logging, mining, oilfield, refuse, fire apparatus and heavy-haul. The suspension, which is approved for 100% off-road duty cycles, is a non-torque reactive suspension with a parallelogram trailing arm design. The suspension is offered in 23,000 lb. and 26,000 lb. capacities and is engineered for independent single suspension mounting that allows for single, tandem or tridem axle truck or tractor applications, according to the company. 
 


The suspension eliminates components to significantly lower weight, reduce maintenance and improve durability, the company said. The integral lower module, for example, is the industry’s first one-piece assembly that includes cast-equalizing beams permanently assembled to the transverse beam with no fasteners. As compared to traditional torque rod and track bar arrangements that transmit forces to the center of the cross-member, the ADZ’s V-rod upper control arm directs lateral forces towards the cross-member and frame rail junction. This new high-strength V-rod design results in improved bushing life, uniform roll rate and allows for a lighter weight cross-member, the maker added. 
 


Other features include: EZ-Align non-welded axle re-alignment, simplified pinion angle setting capability, bolt-on or weld-on axle adapters and multi-functional pivot bushings for improved ride comfort and handling. As a result, the lighter weight ADZ provides increased load capacity and reduced fuel consumption for improved operational efficiency.
