DAF Components unveils new more efficient rear axle

DAF Components has launched a new driven rear axle for coaches and buses that has lower fuel consumption, low kerb weight and long service intervals.

In addition, DAF Components is launching new Euro 3 and Euro 5 PACCAR engines, which run up to 12% more efficiently than their predecessors, according to the company.

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.

DAF Components’ new rear axle – with a total gear reduction of 2.05 – fits into the manufacturers’ 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 about 2%, according to the company. DAF Components says 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 new axle is up to 70 kg lighter than any other driven rear axles for coaches and buses. In addition, 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.

Meanwhile, the range of newly developed Euro 3 and Euro 5 PACCAR engines for coaches and buses are up to 12% more efficient than the engines it is replacing and is based on the reliable and efficient Euro 6 powertrain launched in 2017. They also boast excellent output at incredibly low rpms, reaching maximum torque at speeds as low as 900rpm. This allows for cruising speed to be achieved at just over 1,000rpm, increasing comfort inside the vehicle.

The new Euro 5 PACCAR MX-11 engine is available with power ratings of 300kW/408hp and 330kW/449hp, with torques of 2,100Nm and 2,300Nm respectively. The new Euro 3 and Euro 5 PACCAR MX-13 engines are available with 315kW/428hp with 2,300Nm torque, 355kW/483hp with 2,500Nm, and 390kW/530hp with 2,600Nm.
