DAF is introducing a new air-suspended single reduction double-drive bogie, which has been specially developed for heavy duty applications requiring additional traction that don’t involve the most arduous off-road driving. The new SR1360T double-drive bogie is 375 kilograms lighter than the existing hub reduction tandem for off-road applications and the heaviest loads, and it reduces fuel consumption by more than 5%. The new SR1360T is perfectly aligned with the aims of the DAF ATe programme (Advanced Transport Efficiency) — to further reduce fuel consumption and emissions and improve truck efficiency.
The SR1360T air-sprung tandem axle is available on 6×4 and 8×4 models of DAF CF85 and XF105 vehicles. There are two variants, with technical load capacities of either 21 or 26 tonnes for a total train weight of up to 70 tonnes. For special applications, the GCW can be as high as 120 tonnes. Alongside reductions in fuel consumption and weight, maintenance costs for the new tandem are also lower, as the rear axle oil only requires replacement once every three years or every 450,000 kilometres.
The SR1360T double-drive bogie is especially useful in heavy applications, where additional traction is required due to the high gross combination weights involved. The axle is particularly suited for use in longer distance special types transport and for other applications which are mainly used on-road, but need additional traction to cope with slippery conditions, such as forestry and waste transfer to landfill.
The introduction of the new tandem axle for 6×4 and 8×4 vehicles is perfectly aligned with the aims of DAF ATe, a complete range of solutions to further reduce fuel consumption and emissions and improve truck efficiency. The programme also includes the innovations introduced on the 12.9 litre PACCAR MX engine, such as new pistons and a fully encapsulated exhaust manifold, which on its own is capable of reducing fuel consumption by 3%. In addition, the engine is switched off automatically once it has been idling for five minutes, and the maximum speed ex-factory is limited to 85 instead of 89 km/h, making it possible to achieve a further 2 to 3% reduction in fuel consumption and CO2 emissions. In order to raise the driver’s awareness of the importance of low fuel consumption, information on the current and achieved fuel consumption is provided on the central display on the dashboard as standard.
