Developed by Schaeffler and Siemens Mobility, the intelligent axlebox generator aims to help customers who wish to digitally monitor their freight train fleets in an easy and efficient manner. This project combines the knowledge of both companies in the fields of axlebox generators (Schaeffler) and telematic systems (Siemens Mobility), to create a digital system for improving transparency and increasing efficiency in rail freight transport. Using an integrated generator into the axlebox bearing housing cover, Schaeffler offers an independent power supply for freight cars that is then used for Siemens’ telematics units. These units record information about the train during operation and make the data available via a mobile network.
Independent power supply to replace the supply of power from the locomotive or batteries
The wear-free generator supplies one watt of power starting from around 40 km/h. Through the combination of a continuous supply of power and the Controlguide CTmobile telematic system, services such as condition-based monitoring and immediate data availability can be available. The “wireless” system can easily be retrofitted or replaced and is maintenance-free. In addition, sensors for monitoring the wheelset regarding temperature, vibration, wear, and flat spots on the wheels can optionally be integrated. These components are currently being developed.
