ZF AV 133
The ZF AV 133 is portal drive axle for low floor buses. The drop centre design allows for a full low floor throughout the vehicle which ZF touts as a benefit to improve passenger flow and safety. The AV 133 was launched at the 2015 Busworld Kortrijk trade show and is the successor to the ZF AV 132. The AV 133 weighs less than its predecessor and is also available in a low-weight version that features aluminum spring carriers—lowering the weight by 5 percent.
