Hendrickson has announced the launch of the Softek NXT integrated monoleaf suspension and steer axle system as an available option on both Peterbilt Model 579 and 567 set-forward-axle trucks. It’s the “next generation” of Hendrickson’s  proven, weight-saving monoleaf suspension and steer-axle system.

As well, the Bendix Wingman Fusion driver assistance system can now be ordered as a factory-installed option on Models 579 and 567 highway tractors and vocational trucks. Production has started.

Softek NXT combines the Steertek NXT axle and monoleaf spring technology with an advanced integrated clamp group design. Hendrickson says it saves over 100 lb compared to a traditional two-leaf spring and I-beam axle system. The integrated system is specifically designed for Peterbilt vehicles to help improve ride quality and durability with ease of maintenance. 

The new integrated — and patented — clamp group and monoleaf spring design are said to provide enhanced ride and handling characteristics.

The Steertek NXT axle’s patented two-piece knuckle assembly simplifies kingpin bushing serviceability and includes a new double lip seal to further improve bushing life. In addition, integrated steering-arm and tie-rod attachments increase strength and further reduce weight, improving durability.

Available now in a 12,500-lb rating, Softek NXT is approved for on-highway applications and will soon be available in a 13,200-lb capacity.

Bendix first made Wingman Fusion available in 2015. The system integrates and advances a proven, road-tested suite of Bendix safety technologies – radar, camera, and the vehicle’s brake system – into a comprehensive driver assistance system.

Unlike radar-only systems, says Bendix, Wingman Fusion combines and cross-checks information from multiple sources to deliver enhanced rear-end collision mitigation, alerts when speeding, and braking on stationary vehicles. It also helps drivers avoid additional crash situations, including rollovers, loss of control, and sideswipe crashes while prioritizing alerts to help reduce driver distraction.

Built on the Bendix ESP Electronic Stability Program full-stability system, Wingman Fusion gathers input through radar, video, and the vehicle’s brakes and creates a highly detailed and accurate data picture. With video, radar, and other sensors working together, and not just in parallel, the system is aid to ‘see’ events sooner – alerting the driver and decreasing the vehicle’s speed up to twice as much – to help the driver mitigate potential collisions or lessen their severity. This potent combination results in near zero false alerts or interventions, Bendix claims.

Peterbilt dealers can order the Fusion system with the stand-alone Bendix BlindSpotter side-object detection system with a single option code.
