  • the current collector is moved from the roof of the bus upward against the rail, and an electric connection is thus formed for the duration of the planned stop of the electric bus at the stopping place so that rapid charging can take place during this period.
  • two mutually independent current collectors and corresponding contacting areas at the rail are required in order to be able to form a charging circuit.
  • a contact apparatus is arranged on a roof of an electric bus in such a manner that an arm that can be connected to a charging contact unit that is integrated in a superstructure of the stopping place or in a building can be extended perpendicularly to the direction of travel of the electric bus.
  • the electric bus has to be positioned by a driver in a particularly exact manner in a predefined position at such a stopping place in order to be able to form a connection at all between the electric bus and the charging station.
  • the electric bus may be positioned deeper or higher relative to the charging contact unit during a stop.
  • the contact apparatus or the used contact strips shift relative to a charging contact unit or rail, an electrical contact possibly being interrupted. If parallel rails are used, it is necessary in that case as well, by the way, to position the electric bus in a relatively exact manner in a designated area at the stopping place.
  • a position diverging from the designated position of the electric bus and a one-sided lateral lowering of the electric bus may prevent a successful contact or connection between the vehicle and the charging station and present a significant risk potential. For instance, conductors may be unintentionally contacted or connected and short circuits may occur, which may damage components of the rapid-charging system or harm people in the vicinity.
  • a drive by means of a positioning device is necessary.
  • a position of the electric bus diverging from a designated position and a lateral lowering of the electric bus have to be accommodated by a possible displacement of the contact apparatus or of the contact elements in a horizontal direction transversely to a direction of travel of the electric bus and relative to the charging contact unit and to the vehicle.
  • a drive for displacing the contact elements in the horizontal direction may be required.
  • additional means for detecting the actual positions and the target positions of the contact elements and for controlling the respective drive are required.
  • the object of the present invention is to provide a mounting device and a contact apparatus and a method for mounting a contact apparatus on a mounting device that allow safely forming a contact while keeping the operation of the means of transport cost-effective.
  • This object is attained by a mounting device having the features of claim 1 , by a contact apparatus having the features of claim 7 , by a rapid-charging system having the features of claim 16 and by a method having the features of claim 17 .
  • the mounting device for mounting a contact apparatus of a rapid-charging system for electrically driven vehicles, in particular electric buses or the like, the contact apparatus serves to form an electrically conductive connection between a vehicle and a stationary charging station comprising a charging contact unit, wherein the contact apparatus can be arranged on a vehicle, wherein the contact apparatus comprises a contact device, wherein the contact device can make contact with the charging contact unit, wherein the contact apparatus comprises a positioning device, wherein the contact device can be positioned relative to the charging contact unit and to the vehicle in the vertical and horizontal direction and can be brought from a contact position on the charging contact unit into a mounting position on the mounting device on the vehicle by means of the positioning device, wherein the mounting device forms a receiving opening comprising a guiding device, by means of which the contact device can be position in the mounting position in the horizontal direction, wherein the guiding device is designed to guide the contact device into the mounting position.
  • the contact device when an electric bus, for example, stops at a stopping place, the contact device can be moved by means of the positioning device and can be moved toward the charging contact unit in a vertical and horizontal direction and can be joined with said charging contact unit.
  • a charging contact formed in this manner between the charging station and the vehicle comprises at least two contact pairs, each consisting of a contact element and an associated charging contact element of the charging contact unit.
  • the charging contact unit can form a receiving opening for the contact device, wherein the contact device can be inserted into the receiving opening of the charging contact unit.
  • the receiving opening can preferably be V-shaped. In case the contact element support shifts relative to the receiving opening when the contact device and the charging contact unit are being joined, the V-shape of the receiving opening causes the contact element support to be centered.
  • the receiving opening can form a guide for the contact device when the contact device and the charging contact unit are joined. Potential positional deviations of the vehicle stopping at a stopping place from a designated stopping position can thus be easily compensated in that the contact element support is guided into a contact position at the charging contact unit by the receiving opening.
  • the mounting device is used for mounting the contact apparatus and that the mounting device allows the contact device to be positioned in the horizontal direction transversely to the direction of travel, motor-driven positioning in the horizontal direction is unnecessary.
  • the mounting device forms the receiving opening comprising the guiding device.
  • the contact device which is moved toward the mounting device in the vertical direction by means of the positioning device, enters the receiving opening and is guided into the mounting position by means of the guiding device during the vertical downward movement.
  • the mounting of the contact apparatus or contact device in the mounting position leads to the contact device being positioned for contact formation at subsequent stopping places in such a manner that the contact devices is always positioned below a charging contact unit.
  • the mounting device and the contact apparatus mountable in the mounting device thus represent a solution for horizontal positioning or alignment of the contact unit relative to the charging contact unit that is cost-effective and hardly prone to failure compared to a horizontal drive.
  • the contact device can be centered relative to the guiding device by means of the guiding device. Accordingly, the guiding device can be designed in such a manner that the contact device is centrally aligned or centered on the guiding device transversely to the direction of travel of the vehicle when the contact device is lowered into the mounting device. Consequently, the guiding device can also be of an axially symmetrical design.
  • the guiding device can form a V-shaped receiving opening for guiding the contact device into the mounting position.
  • the contact device is guided in a central area of the receiving opening and into the mounting position by means of the guiding device when being lowered into the V-shaped receiving opening independently of a position above the receiving opening.
  • the receiving opening can also have a different shape that is suitable for the purpose of positioning the contact device and that can guide the contact device into the mounting position.
  • the guiding device can form a linear guide in the vertical direction in the mounting position.
  • the linear guide can be part of the receiving opening.
  • the linear guide can ensure that the contact device is lowered once more in the vertical direction after horizontal positioning, whereby a potentially unintentional horizontal displacement of the contact device due to movements of the vehicle or the like can be safely avoided. Accordingly, the linear guide fixes the contact device in the horizontal direction in the mounting position in a form-fitting manner.
  • the guiding device can be made of plastic or metal and can be formed in a particularly simple and cost-effective manner by one or more sheets, profiles or the like, such as pipe profiles, for example.
  • the mounting device has a cleaning device for the contact device, wherein said cleaning device can be arranged and designed in such a manner that contact elements of the contact device can to come into contact with the cleaning device prior to or after a movement of the contact device into the mounting position.
  • contact elements of the contact device can be cleaned at least during each lowering or placement of the contact device in the mounting position. The same is possible during a vertical movement of the contact device from the mounting position into a contact position. Potential dirt on the contact elements, which might adversely affect the formation of an electric contact connection, can thus be regularly removed from the contact elements without much effort, which substantially increases the operational reliability of the contact device.
  • the cleaning device can be a brush and/or a wiper. It may be envisaged, among other things, that the brush and/or the wiper has an abrasive effect on the contact elements.
  • the wiper can be made of a rubber-like material comprising abrasive particles.
  • the surface of the contact elements can be cleaned and, additionally, an oxide layer present on the surfaces can be at least partially removed, for example.
  • the contact apparatus serves to form an electrically conductive connection between a vehicle and a stationary charging station comprising a charging contact unit, wherein the contact apparatus can be arranged on a vehicle, wherein the contact apparatus comprises a contact device, wherein the contact device can make contact with the charging contact unit, wherein the contact apparatus comprises a positioning device, wherein the contact device can be positioned relative to the charging contact unit and to the vehicle in the vertical and horizontal direction and can be brought from a contact position on the charging contact unit into a mounting position on the mounting device on the vehicle by means of the positioning device, to wherein the mounting device forms a receiving opening comprising a guiding device, by means of which the contact device can be positioned in the mounting position in the horizontal direction, wherein the contact device is designed to be guided the into the mounting position by means of the guiding device.
  • the substantial aspect of the contact apparatus according to the invention is that it has the contact device, which is designed to be guided by the guiding device of the mounting device.
  • the contact device has a shape or elements that can come into contact with the guiding device so that the contact device can be guided into the mounting position by the guiding device.
  • the positioning device can have a pantograph or a swing arm, by means of which the contact device can be positioned relative to the charging contact unit or to the vehicle in the vertical direction.
  • a swing arm an additional linkage may be provided, which stabilizes the contact device relative to the charging contact unit and aligns it in the appropriate direction.
  • a pantograph or a swing arm or a corresponding mechanical drive can be produced in a particularly simple and cost-effective way.
  • the positioning device can further have a transverse guide, by means of which the contact element support can be positioned transversely relative to the charging contact unit or to the direction of travel of the vehicle.
  • the transverse guide can be arranged on the pantograph or on the swing arm of the positioning device. In both cases, the contact device arranged on the transverse guide can thus be displaced transversely to the direction of travel of the vehicle. For example, this displaceability allows an incorrect positioning of the vehicle at a stopping place to be compensated transversely to the direction of travel.
  • potential movements of the vehicle due to a one-sided lowering of the vehicle for entry and exit of passengers can be compensated in such a manner that the contact element support does not shift relative to the charging contact unit in the transverse direction.
  • the transverse guide can be arranged at a distal end of the pantograph or of the swing arm.
  • the transverse guide can be permanently mounted directly to the distal upper end of the pantograph or of the swing arm so that the contact device can be easily moved on the transverse guide.
  • the transverse guide can be realized as a straight linear guide or as a curved linear guide.
  • the curved linear guide can then have a radius of a curve that corresponds to a height of the transverse guide above a roadway.
  • the contact device is arranged on the transverse guide in a freely displaceable manner.
  • This freely displaceable arrangement of the contact device significantly simplifies compensation in case of tilting of the vehicle transversely to the direction of travel due to one-sided lowering.
  • the positioning device is inclined laterally, i.e. transversely to the direction of travel, the contact device staying connected to the charging contact unit and being displaced on the transverse guide.
  • the transverse guide may be designed in such a manner that it is formed as a guide rail or comprises guide profiles for the contact element support.
  • the contact device has a contact element support comprising contact elements.
  • the contact elements can be designed in such a manner that they can make contact with charging contact elements of the charging contact unit so as to form contact pairs.
  • the contact element support can be centered again on the transverse guide in that it is aligned on the transverse guide or centered in a rest position in the mounting position by means of the guiding device.
  • the charging contact unit can be composed of a charging contact element support and of the charging contact elements, wherein the charging contact element support can be made of a plastic material.
  • the charging contact element support can also be made of plastic in one piece.
  • the charging contact elements can be inserted into the charging contact element support or into designated mounts or recesses.
  • the charging contact unit can be realized as a roof-shaped longitudinal rail that can be arranged in a direction of travel of the vehicle.
  • the charging contact elements can be arranged on an underside of the roof-shaped longitudinal rail so that the charging contact elements are not directly exposed to the effects of the weather.
  • the roof-shaped longitudinal rail can have a relatively long shape, making an exact positioning of the vehicle at a stopping place unnecessary.
  • the roof-shaped longitudinal rail can preferably be open at its ends so that the contact element support can also be inserted into and pulled out of the roof-shaped longitudinal rail in the direction of travel.
  • the contact device can be arranged on a roof of a vehicle, which may be the roof of an electric bus or of a tramway car, for example. It may also be envisaged, for example, to position the contact device on the roof of the vehicle in such a manner that it is arranged on a driver side of the roof of the vehicle in the direction of travel. In this way, it is substantially easier for a driver of the vehicle to position the contact apparatus below a charging contact unit because it or its position is in the driver's line of sight.
  • the contact element support can form two, preferably three or more positioning surfaces, which are designed to match guiding surfaces of the guiding device for guiding the contact element support.
  • the positioning surfaces of the contact element support can then come to fit closely to the guiding surfaces of the guiding device so that the contact element support can be accurately positioned into its designated position in the mounting device when the contact device and the mounting device are joined.
  • the guiding surfaces may in particular have a geometry or relative arrangement to one another that matches the positioning surfaces in such a manner that a secure introduction of the contact device into the mounting device into a defined mounting position is ensured.
  • the contact element support can also have two rolling bodies, which are designed to come into contact with a guide track of the guiding device.
  • the rolling bodies can each be realized as a wheel or in the manner of a roller, for example.
  • the contact element support does no longer have to slide along guiding surfaces but can simply roll along the guide tracks without large frictional resistance. Abrasion on the guide track is thus minimized and damage to the contact element support is avoided to the largest extent. Also, the rolling bodies on the contact element support can be easily replaced if they are worn.
  • the positioning device of the contact apparatus has a pivot mechanism, by means of which the contact element support can be inclined relative to a vertical axis of the contact element support.
  • a height of the contact element support is greater than its width or depth, it is advantageous if the contact element support can be inclined relative to the vertical axis of the contact element support and thus also relative to a horizontal roof of the vehicle. In this way, the contact element support can protrude above the vehicle roof far enough for a height of the respective vehicle to substantially increase. In principle, however, this is undesirable because passages of bridges, underpasses and the like might no longer be usable. Furthermore, the aerodynamic properties of the vehicle might possibly be impaired by the contact element support.
  • the mentioned disadvantages are compensated at least in part or completely.
  • the pivot mechanism employed for this purpose can be realized as a linkage of the positioning device.
  • the linkage can translate a movement of the positioning device during lowering of the contact element support into the mounting position into a pivoting movement.
  • an additional drive for pivoting or inclining the contact apparatus can be omitted.
  • the linkage can also be realized as a cam mechanism comprising a lever and a cam disk.
  • the contact element support can be aligned orthogonally relative to the charging contact unit in the contact position and at an inclination relative to a horizontal roof of the vehicle in the mounting position. In connection with the mounting device, the contact element support can thus be inclined during contact formation with the guiding device.
  • the rapid-charging system comprises a mounting device according to any one of claims 1 to 6 and/or a contact apparatus according to any one of claims 7 to 15 . Furthermore, the rapid-charging system can also comprise a charging station and a charging contact unit.
  • the contact apparatus and the mounting device are arranged on a vehicle, wherein the contact apparatus comprises a contact device, wherein the contact device is brought into contact with a charging contact unit, wherein the contact apparatus comprises a positioning device, wherein the contact device is positioned relative to the charging contact unit and to the vehicle in the vertical and horizontal direction and is brought from a contact position on the charging contact unit into a mounting position on the mounting device on the vehicle by means of the positioning device, wherein the mounting device forms a receiving opening comprising a guiding device, wherein the contact device is guided and positioned into the mounting position in the horizontal direction by means of the guiding device.
  • the method provides that after the contact apparatus has been displaced in the horizontal direction relative to a direction of travel of the vehicle because of a contact formation or joining with the charging contact unit, the contact device is returned into the mounting position or original position upon separation of the contact with the charging contact unit and upon return into the receiving opening of the mounting position prior to a vertical movement or positioning of the contact device.
  • the alignment or positioning of the contact device always takes place during a return into the mounting device when the contact device has been moved in the horizontal direction because of the formation of a contact with the charging contact unit.
