Definitions
- the invention relates to a current collector and a method for energy transmission from a busbar to a vehicle by means of a current collector, wherein the current collector comprises a carrier device, a pressure device and a contact pad which forms a sliding contact surface, the carrier device for fastening the Current collector is formed on a vehicle, wherein the pressure device is designed so that by means of the pressure device, the contact strip can be moved relative to a busbar and can be pressed against the busbar to form a sliding contact with a pressure force in a sliding contact position, the pressure device being a rocker unit for Formation of the pressure force with a rocker and a spring device comprises, wherein the spring device is designed to be rotatable, such that the contact pad arranged on the rocker forms the contact pressure force is movable in one direction in the sliding contact layer, wherein the pressure device comprises a holding device that connects the Federeinrich device with the carrier device.
- Such current collectors are known from the prior art and are regularly used on rail vehicles for the transmission of electrical energy from a conductor rail to the vehicle.
- the busbar is usually arranged in the area of the running rails and is also referred to as a so-called third rail.
- a contact strip is attached to a rocker arm, the rocker arm pressing the contact strip with a defined pressing force on a sliding contact surface of the busbar.
- the contact strip is brought into contact with the contact rail by moving the contact strip onto the busbar via a ramp, the rocker then being pushed back over the contact strip and thus the required pressure is applied.
- the pressing force is applied by a spring device which is connected to the rocker arm and actuates it in the manner of a lever.
- the spring device Starting from an unloaded end position of the rocker, the spring device generates the pressure force with a movement of the contact strip as far as a stop or a maximum sliding contact position when the bus is driven onto the busbar. Without contact with a busbar, the contact strip is then deflected to an end position. As a result, any horizontal distance fluctuations in the busbar can be compensated for relative to the current collector or rail vehicle.
- the busbar can be designed for contact with the contact strip from above, below or to the side of the busbar.
- the current collector can then also be designed accordingly in such a way that the contact strip is pressed back in the corresponding direction via a ramp when the contact strip runs onto the busbar and a pressure force is applied in the opposite direction.
- Such current collectors are known, for example, from DE 10 2009 054 484 B4 and US 2013/0081915 A1.
- An extended use of rail networks with vehicles that have corresponding pantographs is often only possible with difficulty, since with cross-network traffic of rail vehicles, a change between energy supply systems must take place regularly.
- the rail vehicles in question are then to be equipped with further pantographs for different busbar systems or also partially with roof pantographs for a contact wire in order to make them usable for the respective rail routes.
- the railways themselves are each equipped with a power supply system, such as a busbar or contact wire, and designed accordingly.
- the pantograph required in each case can then be used with a vehicle.
- pantographs regularly enlarge a cross-section of the rail vehicle so that the pantograph arranged in the area of the rails can easily be damaged if energy is transmitted via a pantograph and a contact wire and there is no busbar.
- obstacles such as objects, structures, plants, etc. can be located in an effective area of the pantograph.
- the invention is therefore based on the object of proposing a pantograph, a vehicle with a pantograph and a method for transferring energy from a busbar to a vehicle, which enables a safe and flexible change between energy supply systems.
- the current collector according to the invention for power transmission from a busbar to a vehicle comprises a carrier device, a pressure device and a contact piece which forms a sliding contact surface, the carrier device for fastening the Current collector is formed on a vehicle, wherein the pressure device is designed so that by means of the pressure device, the contact pad can be moved relative to a busbar and can be pressed against the busbar to form a sliding contact with the pressure force in a sliding contact position, the pressure device being a rocker unit for training comprises the pressing force with a rocker and a spring device, the spring device being designed to be rotatable, such that the sliding piece arranged on the rocker can be moved in one direction into the sliding contact position with the formation of the pressing force, the pressing device comprising a holding device that holds the spring device connects to the carrier device, wherein the carrier device has a carrier device and a pivot device for positioning the pressure device on the vehicle, wherein by means of the pivot device at least the rocker unit together men can be moved with the contact strip between the sliding contact layer
- the rocker unit of the pressure device is accordingly designed to be rotatable so that the unloaded rocker unit with the attached contact strip can be brought from an end position to the sliding contact position on the busbar with the formation of a pressure force.
- the pressure force is applied solely by the spring device. Accordingly, the rocker unit alone enables the contact strip or rocker to move between the sliding contact position and the end position.
- the holding device serves to fasten the rocker unit to the carrier device of the current collector. Accordingly, an axis or axis of rotation for the rocker unit with the contact strip is formed between the rocker unit and the holding device.
- the holding device can preferably be attached to the carrier device in an electrically insulated manner.

- the current collector can be mounted on the vehicle via the carrier device in such a way that the pivot axis runs in the direction of travel of the vehicle. For example, the pressure device or the rocker unit with the contact strip can then be pivoted about the pivot axis in the direction of a floor of a car body or in the direction of a side wall of the car body below the floor.
- the pivoting device can comprise a pivoting drive, wherein the pivoting drive can be connected to a beam of the pivoting device and to the carrier device, such that a rotary movement of the pivoting drive causes pivoting of the beam and the holding device with the rocker unit between the sliding contact position and the custody situation.
