For even better fuel efficiency, higher payloads and enhanced manoeuvrability, DAF Trucks is introducing an Electric Hydraulic Steering (EHS) system on 6×2 tractor and rigid vehicles with a steered pusher axle.
The new system is available across the New Generation DAF truck range, including XF, XG and XG⁺ models, plus the latest XD ‘International Truck of the Year 2023’.
Heavy agricultural and construction-related operations will benefit especially from the advantages of a steered pusher axle. Precise manoeuvrability in combination with an even higher payload makes the steered pusher axle also an excellent solution for waste collection and bulk operations.
DAF’s new Electric Hydraulic Steering system replaces its previous mechanical variant. The two steering arms and the auxiliary drop arm are replaced by an electronically-controlled steering pump unit, which results in a 30kg weight reduction. Thanks to reduced friction, the new EHS system also results in a 0.3% fuel efficiency gain.
In addition, the new system’s components use less space on the chassis, allowing up to 40% larger fuel tanks on the tractor model. The900-litre fuel carrying capacity on the XD, XF, XG and XG⁺ allows for a further reduction in operational costs by refuelling where fuel prices are lowest.
Precise steering
The newly developed Electric Hydraulic Steering system continuously calculates the optimal steering angle for the steered pusher axle based on speed and wheelbase, guaranteeing precise steering. The turning circle of the tractor and rigid chassis models has been further reduced by 12%, resulting in optimal manoeuvrability.
At speeds of over 45 km/h, the new electric hydraulic steered pusher axle locks itself in the straight-ahead position, ensuring maximum vehicle stability. The completely redesigned suspension, guide and lift of the new electric-hydraulicly steered pusher axle add to highest driver comfort.
