Volvo Bus Australia has unveiled a new hydraulically steered tag axle that promises enhanced drivability, efficiency and comfort.

The steerable tag axle is intended for use on Volvo’s three-axle coaches and inter-city buses. These vehicles feature a third axle that is responsive to steering and enables the back wheels to rotate as the bus turns.

"The release of the steerable tag axle to the Australian market has been made possible with the National Transport Commission (NTC) recently approving the Volvo unit under their Performance Based Standards (PBS) regime and will not only increase the comfort and drivability of our buses for operators, but will also increase the profitability of their businesses," says David Mead, General Manger, Volvo Bus.

The steerability of the axle and subsequent rotation of the back wheels reduces the bus’s drag and resistance on the road surface. As a result, the wear and tear on the tyres is reduced while fuel efficiency is enhanced, thus lowering operation costs.

The steerable tag axle also offers enhanced navigability and driving power. It makes tight turns, reversing and manoeuvrability in narrow spaces easier and is ideal for driving in city traffic.

Like the fixed tag axle on current Volvo models, the steerable axle is equipped with air-bag suspension and a bogie lift function. This enables weight to be transferred onto the second axle if needed to prevent wheel slippage on unstable surfaces.

It also ensures a smooth and comfortable ride regardless of whether the bus is empty or crowded. Both the drive and tag axles are equipped with shock absorbers and heavy duty stabilisers which add to the overall comfort and stability of the Volvo bus.

"The steerable tag axle was designed by Volvo to enhance our buses’ drivability and comfort while keeping safety a priority. It’s pleasing to see the approval now for our Australian customers who can benefit like their counterparts globally have for many years," Mead says.
