BS AU 259 is a British Standard on the specification for components for commercial vehicles and buses. The main aim of BS AU 259 is to provide the best industry specifications that ensure the shaft flanges play a positive role in the overall performance of commercial vehicles and buses.
BS AU 259 specifies the nominal dimensions and tolerances which affect interchangeability between cross-tooth propeller shaft flanges, type T, used on commercial vehicles and buses.
Dimensions and tolerances of the mating parts, i.e. type T cross-tooth gearbox flanges, are specified in ISO 8667.
BS AU 259 on cross-tooth propeller shaft flanges, type T is useful for:
The propeller shaft flanges are used for automotive purposes to connect the driveshaft to the transmission, transfer case, and differential. The flanges are also used to connect driveshafts to power take-offs, hydraulic pumps, and a variety of accessories. Henceforth, the components must be built while keeping the best industry design considerations in mind so that the overall performance and operational efficiency of commercial buses and vehicles are not in any way compromised.
BS AU 259 specifies the nominal dimensions and tolerances of the type T propeller shaft flanges used on commercial vehicles and buses.
BS AU 259 specifies the designation of type T propeller shaft flanges that includes the size and type code.
As a result, if you are a type T propeller shaft flange manufacturer, complying with BS AU 259 can ensure your products are fit for purpose and meet the desired performance requirements of the gearbox. Moreover, these dimensions and tolerances can also enhance the interoperability of flanges, which can improve your business’s reach to a wider market.
