DAF launched the first long distance versions of the New CF and New XF at the beginning of the summer and has now introduced a new series of multi-axle and rigid vehicles. The new vehicles are available with common as well as some unique new features.
Up to 7% higher fuel efficiency
All the new DAF vehicles include up to 7% better fuel efficiency as a result of the seamlessly integrated and completely new and innovative down-speeding powertrains.
New ultra-compact EAS: extra chassis layout options and extra payload
The new rigid chassis benefits from the ultra-compact EAS of the New CF and New XF. The EAS now fits completely (i.e. as one single unit) between the first and second front axles (in the 8×4 FAD). This makes it possible to use the free space for the addition of crane legs, toolboxes or extra (fuel) tanks and results in increased frame layout options and extra payload, thanks to its 50 kg lower weight
Higher payloads from 100 up to 250 kilogrammes
Similarly, the latest range of multi-axle tractors and rigids are equipped with powertrain and exhaust configurations that are up to 100 kg lighter in total on average, resulting in higher payload capacity for DAF customers. New axles and optional disc brakes contribute to total weight savings of up to 250 kg for the CF FAD 8×4 for construction applications.
New electro-hydraulic steered trailing axles
One of the most important innovations within the New CF and New XF program is the new steered trailing axle for both tractors and rigids that facilitates maximum manoeuvrability.
The new trailing axle incorporates a newly developed EHS (Electric Hydraulic Steering) system which is 30 kg lighter, resulting in extra payload. The steering is very precise because the EHS continuously calculates the optimal steering angle for the rear axle wheels on the basis of speed and wheelbase. The resulting benefits are most noticeable when driving through urban areas and manoeuvring the truck. The minimisation of frictional losses and the fact that the steering pump is only activated while steering results in an additional 1% reduction in fuel consumption.
At speeds of over 40 km/h, the axle is locked in the straight ahead position and guarantees maximum vehicle stability and supports excellent fuel efficiency. In addition, the trailing axle steering system contains significantly fewer components, which supports first class robustness and reliability.
The new steered trailing axle can be fitted on 6×2 rigids and tractors as well as 8×2 rigids.
The EHS is complimented on 6×2 CF and XF FAN vehicles by a new air suspension that can be quickly lowered 90 mm and lifted 185 mm for fast and reliable loading and unloading of swap bodies.
New dual-mounted trailing axles
DAF is also introducing a new dual-mounted 10 tonne trailing axle, which has a static load capacity of no less than 34 tons. This is can be important when loading and unloading heavy containers. The new axle has reduced kerb weight by 25 kg. When combined with the other New CF and New XF weight reductions, this results in an overall 125 kg of additional payload.
DAF’s new dual-mounted trailing axle can be fitted on 6×2 tractors and rigids, as well as 8×2 rigids.
250kg Weight Reduction for the FAD CF 8×4
This range includes the CF FAD 8×4 rigid with both Construction CF (N3G) and haulage CF (N3) variants. On these models the compact EAS (exhaust after treatment system) incorporates the SCR into the single unit which can fit neatly between the two front axles with a vertical tailpipe, or further down the chassis with a low discharge, to facilitate fitment of heavy cranes. This redesign results in a 115 kg reduction in weight with more chassis space and layout flexibility. The TraXon gearbox is now standard across New CF and New XF models whilst the 16 speed manual gearbox is available as an option, and can be specified on the CF FAD chassis with the single reduction tandem SR1132T and the MX-11 engine up to the maximum 330 kW (450hp) and 2300 Nm. The SR1132T double drive tandem is also now offered with either drum or disc brakes with the later offering a weight reduction of 100kg. In total the New CF FAD 8×4 models can deliver an extra 250 kg payload.
New dedicated lightweight 8×4 mixer chassis throughout Europe
A new dedicated lightweight CF FAD 8×4 mixer chassis is now available with the single reduction (SR1132T) tandem and two 7.1 tonne front axles. This cost effective high performing chassis which is popular in the United Kingdom is now available throughout Europe. As a result of the optimisation of the steering system and the suspension, the use of disc brakes and the new compact EAS unit with vertical tail pipe, the kerb weight of this lightweight truck is a mere 9,150 kg, which sets the benchmark for its class. The unique mixer chassis comes with the new PACCAR
MX-11 engine, in power ratings from 270 to 330 kW (370 to 450 hp).
New double-drive hub reduction tandem axles
For heavy haulage and arduous off-road applications, DAF presents a new double-drive tandem with hub reduction (HR1670T). This axle set boasts a completely new cast-iron axle housing that provides an extra weight reduction of 60 kg.
In order to achieve the highest possible fuel efficiency, even faster final drive ratios (3.46, 3.61, 3.76:1) are available. These ratios allow the engine to operate at even lower revs. To ensure the lowest possible operational costs, oil-change intervals for the new tandem set have been raised to 3 years or 450,000 kilometres.
The new dual driven tandem with hub reduction is available on 6×4 and 8×4 tractors and rigids for heavy duty applications.
Highest body builder friendliness for New CF and XF rigids
DAF has introduced important enhancements to the chassis for industry-leading body builder friendliness. The new Body Attachment Modules (BAM) play an important role in the speedy fitting of a box body, a heavy crane, tipper or hook lift system.
The new and extended hole pattern in the rear-end of the chassis facilitates easy fitment of tail lifts, cranes and boxed bodies and also makes it easy to relocate components or mount a drawbar installation or underrun protection. As a result, the new hole pattern saves body builder costs while shortening vehicle lead-times.
New and innovative Battery Energy Monitoring System
Another new feature is the innovative Battery Energy Monitoring system – BEM for short. This optional system uses a newly developed sensor to measure the exact charging conditions of the battery, and is even able to take environmental conditions into account to ensure the vehicles are ready to work and have the highest availability.
New PACCAR MX-11 and MX-13 engines
In line with the DAF Transport Efficiency philosophy, every effort has been made to obtain the maximum performance from every drop of fuel. The PACCAR MX-11 and MX-13 engines have been given a complete makeover. An important objective during the development of the new powertrains was the reduction of engine revs commonly referred to as ‘down speeding’ as lower revs results in lower fuel consumption. At the same time, the maximum torque of the PACCAR engines was increased significantly, with the maximum torque now available at an amazing 900 revs per minute.
The power of almost every powertrain rose by 7 kW/10 hp to 14 kW/20 hp, while the torque for all of the new engines was increased by 50 to 200 Nm. Furthermore, DAF applies ‘Multi Torque’ on the New CF and New XF, which results in the release of an additional 100 to 150 Nm in the highest gear. This allows driving for longer periods in the highest gear, which in turn optimises fuel consumption and maximises performance.
The newest TraXon: faster and less friction
The new PACCAR MX-11 and MX-13 engines come standard with the latest generation TraXon automated gearboxes. These transmissions have lower friction loss and are characterised by an extremely smooth gear shifting behaviour. Specific shifting strategies are available for Standard Transport, Liquid Transport, Heavy Haulage and Eco Combi’s. In the Construction models of the DAF CF FAD, FAT (rigids) and FTT (tractor) the TraXon transmission comes with off-road software for optimal transmission performance and clutch actuation. When activated, the TraXon shifts extremely fast and at higher revs to ensure maximum traction.
Advanced software functionality for the driveline
As with the first New CF and New XF configurations introduced, the new DAF
multi-axle models boast a completely new electrical and electronic architecture, featuring a new control unit to manage all powertrain components in an integrated fashion. Functionalities such as EcoRoll and Cruise Control have been expanded to further improve their contribution to optimal fuel economy.
Highly efficient rear axles
An important component of the new, faster powertrains are the rear axles designed and manufactured by DAF. Faster reductions of2.05:1 are now available, allowing to cruise at 85 km/h at 1,000 rpm, depending on the driveline specifications. For the new generation of rear axle differentials, the crown wheel and pinion were redesigned in order to ensure optimal longevity and efficiency as well as extremely low noise levels..
With the introduction of eight 2-, 3- and 4-axle rigids and three 3- and 4-axle tractors, Pure Excellence is now the standard throughout DAF’s entirely new range of trucks. Pure Excellence expresses the DAF Transport Efficiency philosophy for achieving the lowest operational costs and highest vehicle availability. At the same time, it is synonymous for the impeccable manufacturing quality and the unmatched driver comfort of the New CF, New XF – and also the New LF.
