The electrical contact system, consisting of a pantograph, a contact head and a roadside contact hood, was developed by Schunk Bahn- und Industrietechnik GmbH in collaboration with the Fraunhofer IVI.
The development aim was to safely transmit high electric capacities, and the currents associated with them, to a stationary vehicle via a compact and robust system. In order to enable the automation of the process, this system was developed as an alternative to plugin systems, which need to be connected manually.
This construction makes fast contact closure possible using only one actuator for positioning the contact head inside the roadside contact hood. No additional actuators (e. g. servo motors) are required.
The contact system developed grants the bus a generous positioning tolerance regarding the roadside contact hood, which will pose no problem for the driving staff. In addition, the contact system balances out sideway movements of the vehicle during the so-called kneeling.
