At Busworld Europe 2011 held in Belgium, ZF Friedrichshafen AG unveiled the new low-floor portal bus axle AV 133, improving on existing designs with higher torque resistance, ease of maintenance and lower weight.

The new generation axle will be introduced in two stages – the first in 2011, and the second stage in co-operation with manufacturers in 2014.

The AV 133 low-floor portal axle has been designed with the primary objective of saving weight, importantly compensating for the additional weight of new generation Euro 6 drivelines.

ZF says the AV 133 is suitable for heavy-weight applications, such as double-articulated buses, because it is designed to withstand higher torques, which is achieved by reinforcing the gearing, bearings and differential.

The new AV 133 can also be adapted for new alternative driveline designs such as trolley, electric and hybrid drives.

ZF say the new axle can easily integrate into existing vehicle platforms because it has the same axle connection points as the current portal axle model, the ZF AV 132.

The AV 132’s advantages in terms of low-floor capability will remain, meaning that extra low floor heights are possible with the AV 133, increasing passenger comfort by doing away with the need for steps and platforms.

This ease of access in turn pays dividends for public transport authorities, as there are shorter changeover times at stops for boarding and alighting passengers.

The new AV 133's design also reduces operating costs with its improved serviceability and maintenance access.
