A suspension rail for guiding a nacelle of a passenger transport gondola system is presented, the suspension rail having the following features:

• a track member having a tread passable by at least one roller of the nacelle and a cable receiving section for receiving a portion of a carrying cable; and
• a busbar part having a conductor section for conducting an electric current and a further cable receiving section for receiving a further section of the carrying cable, wherein the rail part and the busbar part are combined or combined with one another to form a rail profile surrounding the carrying cable, that the carrying cable between the cable receiving section and the other Rope receiving portion is arranged, wherein the cable receiving portion and / or the further wire receiving portion is non-positively and / or positively connected to the supporting cable.

Under a hanging rail can be understood a rail for hanging a nacelle, along which the nacelle can be moved hanging. In contrast to a revolving hoisting rope, a carrying rope can be understood to mean a fixed rope which can be stretched over one or more pylons or fixed to other structural elements such as buildings, secondary suspension ropes or bridges. Under a role, for example, a vertically, horizontally or obliquely oriented guide or drive roller can be understood. Under a drive or busbar part, for example, an elongated, rail-like profile, such as a steel profile can be understood. Under a cable receiving portion may for example be adapted to a diameter of the support cable groove in the driving or busbar part or any other suitable constructive feature for generating a positive or positive connection between the supporting cable and the driving or busbar part understood. Under a running surface can be understood by a navigable by the role of the nacelle surface of the rail part. The tread may be curved in a U-shape, for example, or comprise a plurality of angularly offset partial surfaces. In particular, the running surface or the cable receiving portion may be arranged at a bottom of the running rail part. A rail profile can be understood to mean a hollow profile in the form of a rail composed of two partial profiles. In this case, the rail profile, for example, have one or more, in particular lateral recesses as expansion joints. The conductor section may, for example, be arranged outside a cavity bounded by the rail profile, so that it can be contacted from outside by a current collector of the nacelle. In particular, depending on the embodiment, the conductor section can have one or more sliding contacts which are electrically insulated from the rest of the rail profile for electrical contacting of the current collector.

The approach presented here is based on the recognition that a hanger rail for guiding a nacelle can be realized as a torsionally rigid composite that rests against a fixed point such as a pylon and maintains its alignment along the entire free-hanging part. The suspension rail can be realized for this purpose as an at least two-part rail profile, which is torsionally rigid in the longitudinal direction and flexible in the vertical direction.

Due to the flexibility in the vertical direction, the structure together with the busbar can follow the deflection of the carrying cable. Due to the torsional rigidity in the longitudinal direction can be achieved, for example, that a pantograph of the nacelle and a passable top of the hanger rail are always aligned vertically to each other. For example, the vertical orientation may be fixed to pylons at the ends of a free-hanging portion and may remain the same regardless of the sag of the support rope over the entire length of the section. Such a suspension rail can be used to provide suitable mechanical contact surfaces for the rollers of the nacelle, which can be permanently correctly aligned with the rail profile. On the other hand, this also makes it possible to provide the electrical contacts for the current collector. The contact surfaces may, for example, have a friction-optimized surface.

According to one embodiment, the runner part can be designed hook-shaped. Additionally or alternatively, the busbar part can be designed plate-shaped. For example, while the tread surface forming an outer surface of the hook-shaped rail part while the cable receiving portion forms an inner surface of the hook-shaped rail part. As a result, the rail profile can be combined with the supporting cable with relatively little effort.

It is advantageous if the rail profile has at least one expansion joint for enabling a longitudinal expansion of the lower profile part upon deflection of the suspension rail.

According to one embodiment, the expansion joint can be formed by a recess extending transversely to a longitudinal axis of the suspension rail in the busbar part or the running rail part or both parts.

The recess may divide the busbar part into a first section and a second section. In this case, the first section and the second section may be slidable in the direction of the longitudinal axis. The displacement in the longitudinal direction can be realized for example by means of a correspondingly oriented tongue and groove connection.

Advantageously, the first subsection and the second subsection can interengage in a form-fitting manner at least in sections transversely to the longitudinal axis. As a result, a lateral deflection of the first or second section under bending stress can be prevented.

According to a further embodiment, a conductor section of the first section and a conductor section of the second section may overlap each other in the region of the recess. As a result, in spite of the expansion joint, a continuous power line and a continuous plane electrical contact surface along the conductor section are made possible.

It is also advantageous if the conductor section has an electrically conductive first sliding contact track and an electrically conductive second sliding contact track for contacting a current collector of the nacelle. For example, a sliding contact track can be understood to be a conductor track routed along the conductor section. The two sliding contact tracks can represent different voltage potentials. As a result, a two-pole electrical contacting of the pantograph of the nacelle can be realized. For example, one of the sliding contact tracks can also function as a data line.

It is particularly favorable if the first sliding contact track is arranged on a first side of the conductor section and the second sliding contact track is arranged on a second side of the conductor section opposite the first side. The two sides can be oriented vertically, for example. Accordingly, the first side may be a side of the conductor section on the left in the direction of travel of the nacelle, and the second side may be a side of the conductor section on the right in the direction of travel of the nacelle. This ensures easy accessibility of the conductor section for the pantograph of the nacelle.

Under a chassis frame can be a load-bearing frame structure for carrying the gondola be understood. Under a support arm can be understood a hingedly connected to the chassis frame or the cabin rod or tubular component. By way of example, the cabin can have at least one window section whose transparency can be changed by applying an electrical voltage in order to make the window section opaque. Under a drive unit can be understood at least one electric motor. The drive unit may optionally include a transmission. The current collector can be designed, for example, as a pivotable arm.

According to one embodiment, the undercarriage frame may have a coupling element, which can be lowered beyond an outer contour of the roller, for coupling the nacelle to a conveyor cable. The coupling element can be, for example, a rail-shaped component. Under a hoisting rope can be understood a moving, circulating rope. This allows the nacelle to be used in a circulating cableway system.

The central server device may in particular be a cloud server. By a mobile terminal, for example, a smartphone, tablet or laptop can be understood.

The approach described in more detail below brings together two concepts for public transport systems in a novel way. The first concept is the application of detachable circulating cable cars from urban areas in urban areas as a public transport system. The second concept is the so-called pod transportation, also called personal rapid transport or PRT for short. Here public transport is not grouped into the largest possible units such as trams or local trains, but handled in small, automatically moving cabins. Typically, these cabs operate on closed lanes or rails. Advantages include high flexibility, timetable-independent trips on request, trips without stops, the possibility of reserving individual cabins at an additional cost, and direct access to or between otherwise restricted zones such as transit areas in airports or company premises. In a sense, fleets of self-driving vehicles are a special case of PRT operating on public roads, ie without their own infrastructure.

PRT systems are not common in their classic form (automatic cabs on wheels) apart from local campus systems or mini-networks in airports. The reason for this is that they should have an inaccessible roadway for safe operation. Typically these are rail or asphalt lines that are elevated or run in tunnels. As a result, the infrastructure is expensive (there are no attractive widespread networks possible) and there is a low acceptance of the sometimes massive interventions in the cityscape.

Urbane cable cars are limited by the widespread design as circulating cable cars principle on a straight line course. A change of direction at an intermediate station is possible in principle, but then due to the second drive system associated with high costs. Therefore, urban ropeways can only be used if the city layout has very dominant straight axes or if flying over buildings is an option. For legal reasons and reasons of citizen acceptance, the latter is not an option in many regions, especially in the European market. In addition, today's stations are complex, relatively expensive and very space-intensive or mean in the case of an elevated construction a major intervention in the cityscape. For this reason, stations in urban cable cars are typically not very dense, which limits the usability of such systems.

The approach presented here thus enables the implementation of a local passenger transport with electrically driven, autonomously driving gondolas on a cable car infrastructure in a corresponding operating concept. The core of the approach presented here is, among other things, the combination of a PRT system consisting of individual, autonomously moving cabins with the structure of an urban cable car. The cabins are primarily by a moved electrical drive unit. The conversion to classic circulating ropeways is an optional variant. The ropes or even partially rigid rail sections are not moved, but connect statically the distances between the pylons. As a result, the following advantages are realized.

The low infrastructure costs of the urban cable car are maintained, so that the main disadvantage for classical PRT implementations is eliminated. Cornering is easily possible. Branching through points, over-cornering or multi-lane sections are easily possible. This makes one of the main obstacles to the success of urban cable cars obsolete. In addition, completely new network infrastructures are possible, such as branched "capillary networks" instead of linear routes. All advantages of PRT system are preserved. Stations can be used much more flexibly and can be scaled almost arbitrarily, in order to be able to react to different demands. In the minimal version, stations have about the space required by a hoistway.

1 shows a schematic representation of a gondola cableway system 100 with a hanging rail 102 according to an embodiment. Shown is a basic principle of a cable car with a rigid suspension cable 104 and cabin-individual electric drive, wherein the support cable 104 a supporting element of the hanging rail 102 represents. In the hanging rail 102 is a gondola 106 with one over a support arm 108 with a chassis 110 connected cabin 112 hooked. The structure of the route is over pylons 114 realized that over the fixed suspension cable 104 are connected. The carrying rope 104 is extended by suitable modifications so that there is at least one electrically insulated from the rest of the structure conductor section 116 a busbar of the suspension rail 102 can absorb, so that the conductor section 116 is accessible for a pantograph with sliding contacts. The chassis 110 is equipped with suitable rollers, so that the gondola 106 safe on the suspension rope 104 can move. For example, on the chassis 110 mounted electric drive unit, powered by the pantograph drives at least one of these roles.

2 shows a schematic representation of a cross section through a suspension rail 102 out 1 , Shown is a principle of the suspension rope 104 with mounted driving and guide rails as well as busbar. The hanging rail 102 includes an exemplary hook-shaped rail part here 200 with a tread passable by one or more rollers of the nacelle 202 , which has, for example, a friction- or wear-optimized surface. The track part 200 also has a cable receiving section 204 for receiving a portion of the support rope 104 on. According to this embodiment, the wire receiving portion 204 as a rounded groove in a floor of the track part 200 executed.

The track part 200 is with a busbar part 206 combined into a hollow rail profile, the suspension cable 104 runs within the rail profile and thus of the two rail parts 200 . 206 at least for the most part enclosed. The busbar part 206 includes the ladder section 116 according to this embodiment, having a first sliding contact track 208 and a second sliding contact track 210 is designed for contacting by the pantograph of the nacelle. The two sliding contact tracks 208 . 210 are ever through an insulator 212 from the ladder section 116 electrically isolated. Exemplary are the two sliding contact tracks 208 . 210 on opposite sides of the conductor section 116 arranged. One through the two sliding contact tracks 208 . 210 realized power line can also be referred to as a busbar.

Similar to the track part 200 is also the busbar part 206 with another rope receiving section 214 for receiving a further portion of the support rope 104 executed. According to this embodiment, the busbar part is 206 designed plate-shaped, wherein the further cable receiving portion 214 exemplified by a negative rounding of the support cable 104 facing and the ladder section 116 opposite longitudinal edge of the busbar part 206 is realized. In the assembled state of the suspension rail 102 is the carrying rope 104 between the two cable receiving sections 204 . 214 arranged. For rope fixing or torsional reinforcement, it is advantageous if the support cable 104 between the two cable receiving sections 204 . 214 is trapped.

The 3 to 5 show a schematic structure of a route in the form of the necessary functions of the suspension rail 102 extended suspension rope 104 in cross section and in side view.

3 shows a schematic representation of a suspension rail 102 out 2 in the side view. The hanging rail 102 has an expansion joint in the form of a transverse to a longitudinal axis 300 the hanging rail 102 extending recess 302 both in the busbar part 206 as well as in the track section 200 on. The expansion joint allows a longitudinal expansion of the hanging rail 102 with sagging suspension rope 104 ,

The recess 302 splits the busbar part 206 in a first section 304 and a second subsection 306 that exemplifies by means of a suitable tongue and groove connection 308 with longitudinal expansion of the hanging rail 102 in the direction of the longitudinal axis 300 are mutually displaceable.

In the arrangement shown, for example, a classical steel cable with a round cross-section is assumed. On this carrying rope 104 is a profile with hook-shaped cross section laid, which is the track part 200 forms and via a suitable contact surface on the inside, preceding the cable receiving portion 204 called evenly on the suspension rope 104 rests. The track part 200 is about another profile, which is the busbar part 206 forms, shear-resistant closed, such as by screwing or other suitable connection technology to ensure the torsional stiffness and by another surface, which is attached to the support cable 104 applies to achieve a connection through terminals. Alternatively, the closing of the rail profile takes place without clamping.

At the lower end of the busbar part 206 is mounted on a suitable insulating layer at least one electrical conductor with a suitable sliding contact surface. By way of example, two opposing conductors in the form of the sliding contact tracks 208 . 210 shown. Also possible are any other combinations. Thus, for example, two conductors can be arranged on one and the same side. Also possible are other functionally relevant lines such as data lines.

In the upper part of the hook-shaped slide rail part 200 three flats are formed. A flattening on the top realizes the contact surface for the roller (s) on which the weight of the cabin rests. To optimize the surface may have different shapes and be realized, for example, convex or completely flat cross-section with respect to the actual support cable significantly widened contact zone. By way of example, a surface modified by a coating or modified roughness for friction coefficient optimization is shown. In addition, depending on the embodiment, lateral guide rollers are used whose axis is at an angle to the vertical main rollers, for example at an angle of 90 degrees. For these guide rollers, the rail profile has corresponding lateral contact surfaces.

The rail profile has, as sketched in cross section through the closed shell on a high torsional strength. Without further measures, this would also be accompanied by a certain flexural rigidity, for reasons of flexibility of the load-bearing suspension cable 104 not desired. In the in 4 shown side view, a measure is shown, which is suitable to solve this conflict of goals. For this purpose, for example, the busbar part forming the lower part of the rail profile 206 recessed in regular sections, so that the busbar part 206 sufficient lengths and so the sagging of the support rope 104 can follow. To secure the torsional stiffness from one section to the next, the sections are 304 . 306 of the conductor rail part 206 so intertwined that they can dodge each other in the longitudinal direction, but not in the transverse direction.

The busbar in the form of the conductor section 116 with the two sliding contact tracks 208 . 210 should also be designed so that a longitudinal strain in the course of deflection of the support cable 104 is recorded. Structurally, this is achieved for example by separate and overlapping portions of the busbar, which are both swept by the width of the pantograph, as in 5 is shown.

4 shows a section through a ladder section 116 out 3 along an in 3 shown section line A - A ,

5 shows a schematic representation of a conductor section 116 out 4 , Shown are the two subsections 304 . 306 with overlapping electrical contact surfaces 500 in the region of the recess or the tongue and groove connection. A width of the pantograph is marked by a double arrow.

6 shows a schematic representation of a chassis 110 according to an embodiment, such as one above based on 1 described suspension. The chassis 110 includes a chassis frame 600 , To which according to this embodiment, successively arranged support and drive rollers 602 and lateral guide rollers 604 whose axis of rotation is here for example perpendicular to a rotation axis of the support and drive rollers 602 is aligned, are rotatably mounted. The chassis frame 600 is about a joint 606 with the support arm 108 connected. A cabin-side drive unit 608 , here an electric motor, is with the carrying and driving rollers 602 mechanically coupled and via a pantograph 610 with swivel mechanism with the ladder section 116 the hanging rail 102 coupled electrically conductive. The pantograph 610 For example, has flexible pantograph loop contacts 612 for contacting the sliding contact tracks on the conductor section 116 on.

For example, the cabin 112 via a suspension arm hinged in the direction of travel 108 with the chassis frame 600 connected. The length of the support arm 108 can be shorter than in classic circulating cable car cabins, as the start-up and Abbremsvorgang is electronically controlled and thus less passive "evasion" of the gondola is necessary. The joint 606 then serves primarily to compensate for slopes in the track to keep the load distribution evenly on the main rollers.

Depending on the embodiment, the following variants are possible:

• - At least two successively arranged, vertical support and drive rollers 602 with concave tread and lateral flanges (analogous to rail vehicles) without guide rollers.

Also in 6 an embodiment of the pantograph is shown 610 , Preferably, the current collector 610 on the chassis frame 600 attached, since he receives such an optimal alignment and as few compensating elements in the form of springs or joints are used. The pantograph 610 For example, it is pivotable so that it covers the entire underside of the chassis 110 enabling the transfer of the nacelle, the maintenance or generally the disconnection from the circuit for safety reasons. Depending on the variant of the arrangement of the busbars, the current collector 610 a suitable number of sliding contacts 612 on. In addition, depending on the embodiment, electrical, optical or other interfaces for data exchange with the infrastructure available, for example, detectors for passive optical, mechanical or electrical markers on the route, with certain commands such as holding commands to locked track parts to the control of the cabin 112 are linked.

The electrical energy is from the pantograph 610 to the electric drive unit 608 which is sketched here only schematically. The drive unit 608 generally includes a suitable control unit with power electronics, an electric motor and elements for transmitting power to the driven rollers 602 such as shafts, chains and belt drives and their combination with corresponding gears.

Also part of the drive unit 608 For example, it is a suitable brake system, either directly on the driven rollers 602 or acts on a part of the power transmission. The actuation takes place approximately hydraulically or electrically on brakes or drums analogous to known systems of motor vehicles.

By a suitable choice of the rope diameter or its vertical positioning come the roles 602 . 604 not in contact with the circulating cable during the coupling process. By this means are hybrid operating modes, such as for very steep sections or to extend existing systems, possible.

8th shows a schematic representation of a gondola cableway system 100 for use in a method according to an embodiment. Shown is the principle of sensor technology and wireless data exchange between autonomously operating gondolas 106 with own cabin sensors 800 , which are formed, for example, to wirelessly with a mobile phone mast 802 or with at the pylons 114 mounted communication devices 804 to communicate. For example, the cabin sensors transmit 800 one environment each of the respective gondola 106 representative sensor signal 805 to the mobile mast 802 or to other gondolas. In addition, the position of the gondolas is determined 106 for example, by satellite using a corresponding satellite navigation signal 806 ,

The communication devices 804 are for example with a server device 808 in the form of a cloud-based center for cabin routing and with a user interface for communication with a mobile terminal 810 coupled. The server device 808 For example, it is configured to use user data received via the user interface 812 a control signal 814 to generate and over the communication devices 804 to a control unit 816 the gondolas in question 106 to transfer, with the control unit 816 the control signal 814 used to control the drive unit of the respective nacelle.

10 shows a schematic representation of a gondola cableway system 100 for use in a method according to an embodiment. In contrast to 9 are the gondolas 106 according to this embodiment, using a sensor signal 805 that of trackside sensors 1000 on the hanging rail 102 is provided, controllable. The data transfer takes place as in 9 over the hanging rail 102 ,

• - Schnittstelleninformationen anderer Mobilitätssysteme, etwa ein ankommender S-Bahn-Zug an einer Umsteigestation, oder von nicht mobilitätsbezogenen Datenquellen, etwa das Ende eines Fußballspiels;
• - Positionsdaten von Smartphones regelmäßiger Systemnutzer oder von Fahrzeugen, die per Navigationssystem einen Pendlerparkplatz ansteuern;
• - historische Daten über typische Verkehrsaufkommen global oder auf Nutzerebene, etwa typische Fahrprofile wie „Weg zur Arbeit“ zu bestimmten Tageszeiten etc.

Basically, that includes in the 8th to 10 shown control system for the operation of the gondolas 106 three levels. A top-level service provides an Internet-based service to the end user, and includes destination entry, seat reservation or private cabin reservation, billing and networking with other mobility systems. A middle level converts the end-customer requirements into specific travel instructions to individual cabins, typically specifications for approaching specific destinations at specific times using certain sections of the route. This includes, for example, functions such as routing with route optimization, the load distribution between alternative routes for optimized network utilization and the predictive positioning of gondolas by:

• Interface information of other mobility systems, such as an incoming S-Bahn train at a transfer station, or non-mobility-related data sources, such as the end of a football game;
• - Position data from smartphones of regular system users or vehicles that control a commuter parking space via a navigation system;
• - historical data on typical traffic volumes globally or at the user level, such as typical driving profiles such as "way to work" at certain times of the day, etc.

A lowest level controls the actual movements of the gondolas 106 such as acceleration, braking but also the commands to actuated travel elements such as points or stations. For this level, different data and ways are needed for their exchange. 8th shows a variant in which the gondolas 106 move primarily autonomously and by means of suitable cabin sensors 800 such as ultrasonic, radar, Lidarsensoren or cameras or suitable combinations the distance to leading gondolas or, when approaching infrastructure objects such as switches or stations, the speed regulate. The cabins are equipped with wireless communication devices, which are part of the cabin sensors, for example 800 or the controllers 816 are. These can be used, for example, with the communication devices 804 at the pylons 114 that are always in direct line of sight communicate. As a result, commands to infrastructure elements such as switches or stations in a separate network with low latencies and high security can be transmitted. The communication with the middle level also takes place via the communication devices 804 or, additionally or alternatively, over a data network of a mobile service provider. Position determinations can be realized by locating nearest pylons or satellite navigation.

Alternatively or additionally, the communication takes place via the data line 900 on the hanging rail 102 , This avoids the uncertainties of wireless communication.

As a further variant, it is possible to use elements of the classic control of rail vehicles. These are in particular the track section sensors 1000 on the route, which divide the route into different sections, and by identifying the cabs determine their position relative to the section sensors 1000 allow. As a result, the functionality can be relocated to central control units and the need for sensors and computers in the individual cabins can be reduced. Combinations with the above-mentioned variants are possible, for example as a redundant additional system, in order to increase operating safety.
