SAF-Holland’s Neway ADZ Series Drive Axle Air-Ride Suspension for vocational trucks and tractors has been engineered for applications including construction, mixers, logging, mining, oilfield, refuse, fire apparatus and heavy haul. The ADZ, which is approved for 100 percent offroad duty cycles, is a non-torque reactive suspension with a parallelogram trailing arm design. The suspension is offered in 23,000- and 26,000-pound capacities and is engineered for independent single suspension mounting that allows for single, tandem or tridem axle truck or tractor applications.
The streamlined ADZ eliminates components to reduce maintenance, improve durability and lower weight, increasing load capacity and reducing fuel consumption for improved operational efficiency. The Integral Lower Module, a one-piece assembly, 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 crossmember, the ADZ’s V-Rod Upper Control Arm directs lateral forces towards the crossmember and frame rail junction, resulting in improved bushing life, uniform roll rate and a lighter weight crossmember.
Other ADZ features include EZ-Align Non-Welded axle realignment, simplified pinion angle setting capability, Bolt-on or Weld-on axle adapters and multifunctional pivot bushings to facilitate improved ride comfort and handling. The ADZ Series also is designed to provide a linear roll rate through the permanent connection of the trailing arms and transverse beam; the suspension’s linear roll rate characteristics not only are designed to improve handling and steering characteristics, but also to enhance driver comfort and confidence.
The ADZ 23K series is available through select specialty vehicle manufacturers and is being introduced to major truck OEMs for data book consideration, while the ADZ 26K series is expected to launch in mid-to-late 2010. The ADZ eventually will replace the company’s Neway AD 23K and 26K series suspensions.
