  • an arm 12 is pivotally connected as a current collector bar. More specifically, this pantograph rod (arm) 12 is pivotally provided at a hinge portion 14 fixed to the roof portion 10 such that the arm 12 fully rotates around the fixing portion 14 having a rotation axis formed thereon in the figure plane of FIG. 2 - can be led.
  • the arm 12 carries at the other end, ie opposite the pivot bearing 14, a pantograph head 16 (shown only schematically in the figure), which in an otherwise known manner grinder or electrodes for co-operation with a suitable current-carrying driving voltage line 18 (contact wire, also in the other "Overhead line”).
  • a pantograph head 16 is pressed in the manner shown schematically in Fig. 2 from below against the contact wire 18, for which purpose a corresponding force is exerted on the (pivotally mounted) arm 12 with a spring unit 20 shown schematically as elevation means.
  • the spring unit 20 is designed so that a reliable contact-forming contact pressure of the pantograph head 16 against the contact wire 18 acts for usual driving conditions (including typical tolerance situations).
  • the spring solution schematically illustrated with reference to FIG. 2 has the disadvantage in the realization of the elevation means that an optimization of this spring (ie setting the spring travel, the spring force by means of a predetermined spring constant, etc.) to a suitable average operating condition must: If the spring force is too strong, there are adverse effects on the contact wire 18 and its suspension; on the other hand, if the spring force is set too weak, it can lead to unintentional detachment (and thus to arcing or sparking), not least by dynamic effects in the relative movement between the Pantograph head and overhead contact line.
  • pantograph device according to the preamble of the main claim; advantageous developments of the invention are described in the subclaims. Independent protection in the The invention is further claimed for advantageous use of this pantograph device for an electrically powered bus with more preferred orientation to public transit. It has been found in the context of the preferred application according to the invention that in particular road-bound overhead line vehicles such as such trolleybuses are subject to a particular extent the problem of the invention and, accordingly, can profitably use the present invention.

  • the elevation means In order to realize, in particular, a constant pressure force of the current collector head on the contact wire, it is advantageous for the elevation means to associate sensor means for determining an elevation angle of the arm relative to the roof section (support), such an angle sensor then being characterized by conventional, optical, (electro) mechanical, Piezoelectric or other measuring principles can be realized. Such angle information can then be processed together with the desired value by the control according to the invention in order to keep the pressure constant.
  • a particularly advantageous embodiment of the invention in practical operation is, in addition to the pneumatic or hydraulic elevation according to the invention, the lifting or lowering of the current Receiver rod (including ansitzendem pantograph head) to realize by electric motor acting means.
  • a spindle (stroke) drive it is possible to use the control precision and precision of such an electromotive lifting / lowering operation for part of the stroke ("path section"), more preferably without that along this electromotive path section through the pantograph head already the contact wire would be reached.
  • This remaining path section would then be hydraulically or pneumatically effected in the context of this preferred variant of the invention, in particular with the aim of then there to effect the advantageous force balance or the homogenization.
  • the technology according to the invention permits the setting or adjustment of almost any pressure conditions, for example as a function of a current relative contact wire height.
  • the control functions already available for this purpose now offer further training the possibility of being able to react in a predetermined manner or situationally to further conditions occurring during driving and / or in the environment.
  • an increased driving speed require an increased pressure force, which can then be easily adjusted or adjusted.
  • the detection (alternatively also the electronic card-based readout) of a location with a large contact wire pitch can lead to the pressure force then being increased again (and then reduced equally on a gradient). The same applies to a centrifugal force influence in curves.
  • the invention also makes it possible to detect environmental parameters independently of the driving or contact wire situation and to take them into account appropriately.
  • the present invention allows, in a surprisingly simple and elegant manner, to overcome the disadvantages of existing, generic pantograph devices in the contact wire system by replacing previously rigid mechanical spring behavior in contact pressure with precisely controllable spring behavior by the hydraulic or pneumatic technology of the invention, aided by associated ones Positioning, control and detector functionalities.

  • a rotary bearing 14 At the other end of the arm 12 is mounted in a rotary bearing 14, which is fixedly mounted on a support 10 (here: roof section of a trolleybus not shown in detail as a means of transport in public transport).
  • Fig. 1 further shows a pneumatic cylinder 22 as elevation means, which in turn is supported at one end on the support 10, the other end is articulated on the arm 12 so that in response to an operation of this Pneumatic unit engages a cylinder tappet 24 of the pneumatic unit on the arm 12 and exerts a force on this and then presses it with the head 16 against the contact wire 18.

  • a sensor 40 coupled to the arm 12 as a rotary encoder detects a current elevation angle of the arm 12 (to that extent corresponding to a height of the current collector head relative to the support 10) and supplies this signal as an actual value 38 to the control unit 34.
  • the elevation height, the contact wire height and the contact pressure are in a functional or control-compatible relationship with each other, for example, from the sensor 40 (via a suitable characteristic) a pressure setpoint could be derived, and then to allow a constant contact pressure.
