Description

The invention relates to a wiring device and a pantograph designed for this purpose for vehicles powered by contact wires, in particular trolleybuses (0 buses), which can also run independently of the contact wire system. Such vehicles have either an additional internal combustion engine or a corresponding accumulator, from which the electric drive is then fed at times.

The connection and disconnection of rod pantographs with their current shoes to or from the two parallel contact wires can be done either by hand, using the existing safety ropes or an auxiliary rod carried along, or from the driver's seat using existing technology on the vehicle. To facilitate the wire-on process, it is known to use wire-on aids. Such connection aids can, as after the DE 26 04 535 B1 is claimed to be arranged at the ends of the rod pantograph or can, as well as after DE 32 44 945 C1 is described, be attached to the contact wires in pairs. Relevant publications on this are also DE 912 232 B and U.S. 3,162,673 A .

The arranged on the rod pantographs Wiring aids have not proven themselves because of this, as already after the DE 32 44 945 C1 it was found that the dynamic behavior of the pantographs is adversely affected.

In practice, funnel-shaped or roof-shaped hoods made of metal or plastic that overlap the respective contact wire have hitherto been used as wiring aids. The rod pantographs with their current shoes no longer have to be placed exactly on the contact wires, but can be attached to the hoods that are slanted downwards on both sides of the respective contact wire. The current shoes then slide along the slope of the hood on the underside into their current pick-up position on the contact wires. The wiring process always takes place when the vehicles are at a standstill, in which case they must be at a specified location.

Wiring aids of this kind are used at the points where the vehicles are planned to be disconnected from and connected to the contact wires. Above all, the parking spaces for the vehicles come into consideration or also those places where the vehicles have to pause or stop on their course so that other vehicles can pass.

For the wiring process, the exact position in which the vehicles must stand under the wiring aid is marked accordingly. The wiring is particularly cumbersome when there are frequent breaks in the routing of the contact wires. The vehicles then have to drive through such interruption points under their own power.

Taking the precisely specified position and wiring it up is time-consuming, especially for trolleybus operation, and usually hinders the flow of traffic. An interruption in the route of the contact wires often occurs at such points as level crossings and other crossing points of contact wires (catenary wires), mainly when the voltage of the crossing wires is different. With single-track contact wire systems, vehicles must always be disconnected and connected when they meet on the route.

In order to allow wiring of the rod pantographs with their current shoes to the contact wires in the driving movement of the vehicles, after the DE 10 2011 121 229 A1 proposed to form the wiring device as a hood-shaped guide that covers the two contact wires of a two-pole catenary from below over a large area.

The hood-shaped guide consists of an insulating material and has bands on the underside on both longitudinal sides of the contact wires. The bands run conically from the inlet for the current shoes of the pantograph rods in the direction of travel to the contact wires. When wiring, the two current shoes of the rod current collectors slide along the hood-shaped guide along the boards up to the contact wires and are aligned for the wiring. In order to prevent the current shoes from jumping over onto the respective adjacent contact wire, the middle barriers can be designed higher than the outer barriers.

The wiring device can be designed for both directions of travel. The inlets for the two current shoes are positioned on the underside of the hood-shaped guide, in the middle, from where the bands run conically to the longitudinal sides of the contact wires in both directions towards the contact wires.

Such an embodiment variant is intended for single-lane contact wire systems that are used in both directions. Sensors can be attached to the hood-shaped guide, which signals the position of the vehicle relative to the guide. Additional sensors monitor that the current shoes of the rod pantographs are inserted in the correct inlet.

For wiring, the vehicles drive into a predetermined area under the wiring device, in which they receive a signal for wiring from the sensors on the hood-shaped guide. Wiring is done while driving, without the vehicles having to stop.

When driving, the rod pantographs can be automatically removed from the contact wires at the end of each contact wire run by a corresponding signal. In the case of single-track contact wire systems, such a signal can also be triggered by an oncoming vehicle. A logic can be used to determine which vehicle has to pull its pantograph rods from the contact wires. The rewiring then takes place in a predetermined stretch of road with a rewiring device that is intended for two driving directions.

As has been found in practice, the wiring device is too bulky and thus spoils the appearance of the street. Significant snow loads can occur in winter, which require a robust suspension. This means that the attachment of such wiring devices is only possible to a limited extent.

The task is to create a wiring device in conjunction with an associated pantograph for vehicles powered by contact wire, in particular trolleybuses, which enables the wiring process to be carried out during the driving movement and the wiring device is designed in a light and simple design so that it can be used at any point in the Section can be used.

The object is achieved according to the invention by the characterizing features of claim 1. The features of the dependent claims describe advantageous configurations of the wiring devices with the associated current collectors.
The solutions relate to catenary wire-fed vehicles, in particular trolleybuses, which can also drive independently of the catenary wire system with their own drive in the unwired position.

In order to ensure uninterrupted driving operation, a wiring device according to the invention is attached at those points at which the course of the catenary is interrupted at the beginning of the further course of the catenary. In the case of single-track contact wire systems, contact wire points can also be installed to allow oncoming vehicles to pass. As has also proven to be advantageous, the wiring devices can be installed on any section of track. On sections of track where the known pantographs often derail, the wiring device according to the invention with the associated pantograph according to the invention ensures protection against derailment. According to the solution of claim 1 and the features of its subclaims, the vehicles drive up to the wiring with their spacer element designed as a v-shaped traverse to the wire or rail-shaped guide, which is positioned centrally between the two contact wires. The spacer element designed as a v-shaped traverse is attached to the upper end of a one- or two-rod pantograph and fixes the current shoes at the distance between the contact wires.

When the vehicles are moving, the spacer element slides with one of its inner sliding surfaces along the guide into its guide groove for wiring, in which the spacer element is then guided on the upwardly inclined guide with the current shoes up to the two contact wires and thus the Wiring done. In other solutions not claimed here, the wiring device consists of two guide plates, which are attached opposite one another on the outer sides of the two contact wires, at a slope from bottom to top towards the contact wires. A spacer element made of an electrical insulating material is arranged at the upper end of the associated rod pantograph, which spacer element fixes the current shoes at the distance between the contact wires. The pantograph can in turn be a single or double pantograph. In the case of the single-rod current collector, the spacer element is designed as a V- or U-shaped traverse on which the current shoes are arranged.

For wiring, the vehicles can drive up to one side of the guide plates with their rod pantograph, whereby this then slides with one of its current shoes along one of the guide plates up to the contact wires by lateral pressure during the driving movement of the vehicles and is wired in this way. Compared to the known single-wire funnels, the guide plates have a lower mass and offer a smaller surface for the snow load in winter. The guide plates can also be arranged for additional security to the wire or rail-shaped guide, according to claim 1.

The spacer element, designed as a V- or U-shaped traverse, can preferably be resiliently rotatably mounted on the single-rod current collector in order to compensate for possible differences in height and lateral position of the two contact wires. Such differences in height of the contact wires to the vehicle kings particularly occur when driving through curves due to the inclination of the vehicles.

The current shoes are fastened to spring elements on the V-shaped or U-shaped traverse, the spring elements being designed to be resilient at least on both sides of the contact wire. Such an arrangement is with the utility model DE 20 2012 011 387 U1 claimed. Here the spring elements for damping are connected in or with a block made of a rubber-like mass.

Any differences in the distance between the contact wires can be compensated for by means of the spring elements.

By connecting the two current shoes to one another by means of a spacer element, lateral and horizontal forces acting on the current shoes are halved. The running of the current shoes on the contact wires is more stable despite the higher mass on the single-rod pantograph, due to the horizontal and vertical springing and the mutual support of the current shoes. Unwiring occurs significantly less.

The invention is explained in more detail below using exemplary embodiments. In the accompanying drawings show:

• 1 a side view in the direction of travel of a wiring device consisting of a wire or rail-shaped guide and an associated single-rod current collector with a spacer element designed as a v-shaped crossbar with current shoes at the upper end,
• 2 a view after 1 longitudinally on a contact wire with the wiring device,
• 3 a side view in the direction of travel of a wiring device, which consists of two guide plates, which are each attached opposite one another on the outside of the two contact wires in a slope from the outside in to the contact wires and an associated single-rod current collector with a U-shaped at the upper end Traverse designed spacer element with current shoes.

The wiring device 1 after 1 consists of a wire or rail-shaped guide 2, which is attached by means of a bracket 11 to spacers 3 between the contact wires 4 and 4'. The guide 2 runs in the direction of travel at an incline B upwards to the contact wires 4, 4' ( 2 ).

Arranged at the upper end of the associated, preferably single-rod current collector 5 is a spacer element 6, which consists of an electrically insulating material and is designed as a V-shaped traverse, with current shoes 7 and 7'. The current shoes 7 and 7' have the same distance A from one another as the contact wires 4, 4'. The spacer element 6 has sliding surfaces 8 and 8' on its inner sides, which run towards a guide groove 9 located in its apex.

The rod pantograph 5 is moved up to the guide 2 with one of the sliding surfaces 8 or 8 ′ of the spacer element 6 during the driving movement of the vehicles and then slides with its sliding surfaces 8 or 8 ′ along the guide 2 up to the guide groove 9 . The rod pantograph 5 is thus positioned with its current shoes 7 and 7' exactly under the two contact wires 4 and 4'. As the travel movement continues, the spacer element 6 then slides along the incline of the guide 2 up to the contact wires 4 and 4′, as a result of which the current shoes 7 are then wired. Since the current shoes 7, 7' have a distance of approx. 700 mm to one another, the rod current collector 5 only has to be roughly aligned with the guide 2.

Advantageously, the spacer element 6 is articulated and resiliently attached to the upper end of the rod current collector 5, whereby in addition to the resilience of the rod current collector 5 there is a vertical resilience of the current shoes 7, 7' and thus the sprung mass is lower.

The current shoes 7, 7' are also preferably arranged on spring elements 10a and 10a'. As per the utility model DE 20 2012 011 387 U1 has already been proposed, the spring elements for damping are connected in or with a block made of a rubber-like mass.

The spacer element 6 can also be arranged at the upper end of a two-rod pantograph between the rods.

This allows vehicles with two-rod pantographs to be retrofitted.

When solving 3 the wiring device 1a consists of two guide plates 12 and 12', which are attached opposite one another to spacers 3a on the outer sides of the two contact wires 4, 4' at a slope from the outside inwards to the contact wires 4, 4'. A spacer element 6a made of an electrically insulating material is arranged at the upper end of an associated pantograph. which fixes the current shoes 7a, 7a' at a distance (A) between the contact wires 4 and 4'.

The spacer 6a is after 3 designed as a cross member 13 and preferably arranged by means of springs 14 in an articulated, resilient manner at the upper end of a single-rod pantograph 5a. As a result, in addition to the springing of the rod current collector 5a, there is a vertical springing of the current shoes 7a and 7a'.

The power shoes 7a and 7a 'are also as after 1 preferably mounted on spring elements 10a and 10a'.

After the solution 1 as well as after 3 the spring elements 10, 10 'or 10a, 10a' on the spacer element 6 or 6a can be arranged at an angle opposite to the direction of travel to the contact wires 4, 4', whereby the pantograph 5 or 5a with the spacer element 6 and 6a and the spring elements 10, 10' or (10a, 10a') with the current shoes 7, 7' or 7a, 7a' has an offset shape. With such a design, vehicles can also be used on route sections with a low contact wire height.

After the solutions 1 as well as after 3 means known per se can be provided which signal the position of the vehicle with its rod current collector 5 or 5a to the wiring device 1 or 1a on the vehicle and the rod current collector with its spacer element 6 or 6a and the current shoes 7, 7' or 7a, 7a' align the correct inlet.
