Abstract
A cleaning means related to a vehicle-related system for driving an electrically propellable vehicle along a roadway. The vehicle has three sources of power: a vehicle-related power generator, a set of batteries and vehicle-external electric stations. The vehicle is provided with a current collector which is displaceable up and down and sideways in relation to the direction of transportation, in order to be brought into mechanical and electrical contact with elongated tracks positioned below the roadway and comprising a conductor adapted to be connected with an electric station. The cleaning means is rotatably fastened in an upper area thereof about a horizontally oriented axis of rotation and adapted to clean the track from loose obstacles and/or yield to solid obstacles. The cleaning means and the axis of rotation are movably disposed in vertical direction by means of a resilient member. The cleaning comprises a forwardly directed edge portion oriented in the direction of travel, the edge portion comprising a point which may be brought into contact with the track and the conductor.
