Abstract: A power supply device for a vehicle includes at least one contact head which can be connected to a vehicle and can be brought in contact with a docking station, wherein a contact head roll mechanism is rotatably connected to the at least one contact head and connected so as to be able to be brought in contact with the docking station, where the contact head roll mechanism includes at least two rolls or at least two rollers, via which a rolling contact can be established between the at least one contact head and the docking station, and where a first roll or a first roller is arranged on a first flank of the at least one contact head, and a second roll or a second roller is arranged on a second flank, located across the first flank, of the at least one contact head.

Abstract: A power supply device for a vehicle, in particular for a utility vehicle such as an electric bus or an electric heavy goods vehicle, wherein the power supply device includes at least one contact head that can be brought in contact with a docking station to establish an electrical connection, and includes at least a first pivot arm that is connected to the at least one contact head, where the at least first pivot arm is connectable to a vehicle so as to be rotatable about a first axis and a second axis that extend at an angle from one another, where the first axis extends parallel to a transverse vehicle axis, and the second axis extends parallel to a longitudinal vehicle axis so as to allow for more flexible movability of the contact head.

Abstract: A device and method for controlling a pneumatically actuated current collector for a vehicle, wherein the device includes a controlled system having a first pressure controller, a second pressure controller, and an actuation device, where at least one sensor, which is connected for signal conduction to a contact force controller of the controlled system, can be advantageously arranged on the current collector, the first pressure controller is coupled to the contact force controller, the second pressure controller and a pressure supply for signal conduction, the second pressure controller having a connection point for an actual pilot pressure from the first pressure controller, and signal-conducting connections are provided between the second pressure controller and the pressure supply and between the second pressure controller and the actuation device such that rapid adaptation of a contact force to variable operating conditions is enabled.

Abstract: An electrical contacting apparatus for the current collector of a vehicle, includes at least an electrical first contact body that is coupled via at least a first spring apparatus to at least a first bearing apparatus, wherein the at least first bearing apparatus is connectable to a current collector linkage or to a current collector holder and where the at least first contact body is electrically connectable to the vehicle, where the at least first contact body and the at least first bearing apparatus are electrically insulated from each other such that it becomes possible to dispense with separate insulators for electrically insulating a current collector from its environment.

Abstract: A rocker for a current collector of a vehicle includes at least one first contact strip connected to a first lever arrangement which is coupled to a first bearing device, and connected to a second lever arrangement which is coupled to a second bearing device, wherein the first bearing device and the second bearing device are connectable in an articulated manner to a current collector linkage, where a first torsion spring is fixedly connected to a lever of the first lever arrangement and non-rotatably via a displaceable bearing to the first bearing device or is connected non-rotatably via a displaceable bearing to a lever of the first lever arrangement and fixedly to the first bearing device, where the first torsion spring simultaneously forms a torque transmission device and a spring device such that a lightweight, compact and nevertheless robust arrangement for collecting current is thereby obtained.
