Boasting 2% lower fuel consumption thanks to minimised internal friction and a high-speed total reduction, an unmatched low kerb weight and an extremely long service interval, with the highest durability and greatest passenger comfort that DAF Components has offered to date: the new, driven rear axle for coaches and buses is raising the bar in just about every way. DAF Components will also be unveiling the new Euro 3 and Euro 5 PACCAR engines, which run up to 12% more efficiently than their predecessors.
The new, driven rear axle – including a new suspension system – and the new engines will make their debut at Busworld 2019, which will be held from 18–23 October in Brussels.
New axles: Minimum consumption, maximum comfort
Just like the completely new range of engines, the new rear axle – with a total gear reduction of 2.05 – fits seamlessly into DAF Components’ down-speeding philosophy: maximum performance at unprecedented lowest rpms ever, which minimises fuel consumption and reduces noise for maximum passenger comfort. The new rear axle allows fuel consumption to be reduced by approximately 2%. This is partly due to the newly developed crown wheel and pinion set, which ensures that as little energy as possible is lost to friction. The axle also sets a new standard for weight reduction, without sacrificing robustness. The new axle of DAF Components is up to 70 kg lighter than any other driven rear axles for coaches and buses. An additional bonus is that the oil in the axle body only needs to be changed once every 540,000 kilometres, leading to even greater levels of uptime for the coach or bus.
New engines: Maximum performance with minimum RPMs
The range of newly developed Euro 3 and Euro 5 PACCAR engines for coaches and buses is up to 12% more efficient than the engines it is replacing and is based on the equally reliable and efficient Euro 6 powertrain launched in 2017. The power sources are unparalleled in their efficiency and quiet operation, and boast an excellent output at incredibly low rpms, reaching maximum torque at speeds as low as 900 revolutions per minute. This allows for cruising speed to be achieved at just over 1,000 rpm, increasing comfort inside the vehicle.
