Description

Die Erfindung betrifft ein Niederflur-Fahrwerksfahrzeug in Multigelenk-Bauweise und mit Fahrwerken mit üblichen Raddurchmessern, Achsabständen und Einstiegsbereichen mit einer niedrigen Einstiegshöhe von bis zu 250 mm sowie einer zwischen der Fahrerkabine und der ersten Achse des Niederflurfahrzeuges im vorderen ersten Einstiegsbereich angeordneten für Rollstuhlfahrer geeigneten und durch den ersten Einstieg zugänglichen sinnvoll nutzbaren Multifunktionsfläche nach dem Oberbegriff des Anspruchs 1, wobei die Multifunktionsfläche aus einem horizontalen Zwischenniveau gebildet wird.The invention relates to a low-floor undercarriage vehicle in a multi-articulated construction and with undercarriages with the usual wheel diameters, center distances and entry areas with a low entry height of up to 250 mm and one arranged between the driver's cab and the first axle of the low-entry vehicle in the front first entry area and suitable for wheelchair users accessible by the first entry usable multifunctional area according to the preamble of claim 1, wherein the multifunctional area is formed from a horizontal intermediate level.

Niederflurfahrzeuge sind aus dem Stand der Technik hinlänglich bekannt. Ein derartiges Fahrzeug wird beispielsweise in der WO 00/64721 A2 beschrieben. Darin geht es darum, trotz Verwendung von konventionellen Radsatzfahrwerken die Unterschiede im Niveau des Bodens (Flurs) im Bereich oberhalb der Fahrwerke und dem Niveau im Bereich der Einstiege durch in Fahrzeuglängsrichtung verlaufende Rampen auszugleichen. Außerdem können gegebenenfalls auch noch quer zur Fahrzeuglängsrichtung Rampen im Bereich der Türöffnungen angeordnet sein, die vor der Fahrzeuglängsachse enden. Eine rollstuhlfahrergerechte Fläche mit einem für Rollstuhlfahrer uneingeschränkt nutzbaren Multifunktionsbereich wird darin nicht offenbart.Low-floor vehicles are well known from the prior art. Such a vehicle is used, for example, in the WO 00/64721 A2 described. The aim is to compensate for the differences in the level of the floor (corridor) in the area above the chassis and the level in the area of the entrances by using ramps running in the longitudinal direction of the vehicle despite the use of conventional wheelset trolleys. In addition, ramps can optionally also be arranged transversely to the longitudinal direction of the vehicle in the region of the door openings which end in front of the longitudinal axis of the vehicle. It does not disclose an area suitable for wheelchair users with a multifunctional area that can be used by wheelchair users without restrictions.

Ein übliches Schienenfahrzeug in Form einer Straßenbahn wird in der US 1,130,296 beschreiben. Die hier beschriebenen Rampen dienen dazu, weitere Stufen im Fahrzeug zu verhindern. Das Fahrzeug selbst kann aber nur über eine relativ hohe Stufe erreicht werden und ist insofern für Rollstuhlfahrer völlig ungeeignet.A common rail vehicle in the form of a tram is in the US 1,130,296 describe. The ramps described here serve to prevent further steps in the vehicle. However, the vehicle itself can only be reached via a relatively high level and is therefore completely unsuitable for wheelchair users.

Seitens der Fahrgäste wird für 100% Niederflurfahrzeuge ein barrierefreier Einstieg gewünscht. Dazu gehört auch ein moderater vertikaler Spalt am Einstiegsbereich zwischen Einstiegskante am Fahrzeug und der Bahnsteigkante. Zusätzlich besteht der Anspruch, rollstuhlfahrergerechte Flächen mit möglichst breitem Zugang auf möglichst flachen Fahrwegen zu realisieren, die großzügige, lichte Platzverhältnisse und einen für diese Zwecke empfohlenen Wendebereich bieten.On the part of passengers, a barrier-free entry is desired for 100% low-floor vehicles. This also includes a moderate vertical gap at the boarding area between the boarding edge on the vehicle and the platform edge. There is also the requirement to realize wheelchair accessible areas with the widest possible access on the flatest possible routes, which offer generous, clear space and a recommended turning area for this purpose.

Seitens der Betreiber wird hinsichtlich Verschleißarmut und Wartungsfreundlichkeit von Fahrzeugen eine möglichst einfache Fahrwerkstechnologie gefordert. Dazu besteht der Wunsch nach für die Fahrgäste möglichst harmonischer Abstimmung zwischen der Fahrwegsinfrastruktur an den Haltestellen, hauptsächlich den Bahnsteigen, und der Einstiegssituation am Fahrzeug mittels einfacher Technologie, idealer Weise ohne die Verwendung von zusätzlichen Hilfsmitteln wie Niveauregulierung am Fahrzeug, Hubliften oder Klapprampen für den Einstieg von Rollstuhlfahrern an den Bahnsteigen.The operator demands that the chassis technology be as simple as possible with regard to low wear and ease of maintenance of vehicles. To there is a desire for the passengers to coordinate the route infrastructure at the stops, primarily the platforms, as harmoniously as possible and the entry situation on the vehicle using simple technology, ideally without the use of additional aids such as level control on the vehicle, lifting lifts or folding ramps for boarding Wheelchair users at the platforms.

Weiter wird von Betreibern die angebotene Fahrzeuggestaltung immer vom nominalen Zustand, also mit neuem Rad (maximaler Raddurchmesser), gesehen.Furthermore, operators always see the vehicle design offered from the nominal condition, i.e. with a new wheel (maximum wheel diameter).

Aus dem Stand der Technik sind Schienenfahrzeuge mit unmittelbar hinter der Fahrerkabine angeordneten Mehrzweckabteilen bekannt, die über zusätzliche Hilfsmittel wie Hubplattformen oder Klapprampen für Rollstuhlfahrer zugänglich sind. Ebenso sind Mehrzweckabteile bekannt, die zwar ohne Hilfsmittel erreichbar sind, aber nicht uneingeschränkt rollstuhlfahrergerecht gestaltet sind. Allerdings sind bisher keine Lösungen bekannt, nach welchen bei entsprechend niedrigem Einstieg ohne zusätzliche Hilfsmittel ein rollstuhlfahrergerecht dimensionierter Mehrzweckbereich erreichbar ist.Rail vehicles with multipurpose compartments arranged directly behind the driver's cabin are known from the prior art and are accessible to wheelchair users via additional aids such as lifting platforms or folding ramps. Multipurpose compartments are also known, which are accessible without aids, but are not designed to be wheelchair accessible without restrictions. However, no solutions are known so far according to which a multipurpose area suitable for wheelchair users can be reached with a correspondingly low entry without additional aids.

Der Begriff "rollstuhlfahrergerecht" charakterisiert dabei die Zugänglichkeit des Multifunktionsbereiches unmittelbar angrenzend an die Fahrerkabine mittels breiter Einstiegs- und Durchgangsbereiche am vorderen ersten Einstieg sowie die Flächen und die Fahrwege, die zu diesem Bereich führen, die besonders geringen Neigungen mit Steigungen weniger als 7% aufweisen und eine lichte Weite, die dem Rollstuhlfahrer ein freies Wenden des Rollstuhles ermöglicht.The term "suitable for wheelchair users" characterizes the accessibility of the multifunctional area directly adjacent to the driver's cab by means of wide entry and passage areas at the front first entrance, as well as the areas and routes leading to this area, which have particularly low inclinations with gradients of less than 7% and a clear width that enables the wheelchair user to turn the wheelchair freely.

Ein Einstiegsniveau kleiner als 250 mm bei neuem Rad (maximaler Raddurchmesser) wird derzeit weltweit nur durch ein Fahrzeugkonzept erreicht, welches nicht als Multigelenks-Architektur mit herkömmlicher Fahrwerkstechnologie ausgeführt ist, wobei der hohe Komplexitätsgrad der Rad- und Antriebsanordnung betriebsbedingte Verschleißnachteile sowie einen höheren Instandhaltungsaufwand bewirkt.An entry level of less than 250 mm for a new wheel (maximum wheel diameter) is currently only achieved worldwide by a vehicle concept that is not designed as a multi-joint architecture with conventional chassis technology, whereby the high degree of complexity of the wheel and drive arrangement results in operational wear and tear as well as higher maintenance costs ,

Bisher ist es nicht gelungen, einen für Rollstuhlfahrer uneingeschränkt nutzbaren Multifunktionsbereich, unmittelbar angrenzend an die Fahrerkabine und dem vorderen ersten Einstieg, bei Einstiegshöhen < 250 mm, vorzugsweise 200 mm, zu Verfügung zu stellen, welcher den Einstieg ohne zusätzliche Hilfsmittel wie Hublifte oder Klapprampen ermöglicht. Insbesondere Einstiegshöhen < 250 mm, vorzugsweise 200 mm, können bislang nur durch besonders aufwendige und extrem komplexe Sonderkonstruktionen der Räder und Radsteuerungen bei neuem Raddurchmesser realisiert werden, die jedoch im Lebenszyklus enorme Nachteile durch hohen Verschleiß an der Rad-Schiene-Schnittstelle und dadurch bedingte hohe Wartungs- und Instandhaltungskosten hervorrufen.So far, it has not been possible to open a multifunctional area that is fully usable for wheelchair users, directly adjacent to the driver's cab and the front entrance, at entry heights <250 mm, preferably 200 mm To make available, which enables entry without additional aids such as lifting lifts or folding ramps. In particular, entry heights <250 mm, preferably 200 mm, have so far only been possible through particularly complex and extremely complex special constructions of the wheels and wheel controls with a new wheel diameter, which, however, have enormous disadvantages in the life cycle due to high wear at the wheel-rail interface and consequently high ones Cause maintenance and repair costs.

Zur Zeit werden bei Fahrzeugkonzepten mit konventioneller Fahrwerkstechnologie mit üblichen Achsabständen und kleinsten Raddurchmessern von 500 mm im verschlissenen, minimal zulässigen Raddurchmesser zur Erreichung von niedrigen Einstiegshöhen in Kombination mit rollstuhlfahrergerechten Multifunktionsflächen drei Lösungsvarianten verwendet:

  • Zum einen wird versucht, die Einstiegshöhen am Fahrzeug größer oder gleich 250 mm auszuführen, wodurch eine gute Abstimmung an Bahnsteigshöhen um die 250 mm erreicht wird, sodass der Niveauausgleich zwischen Fußbodenhöhe unmittelbar am Einstieg und Multifunktionsbereichen zur Fußbodenhöhe über den Fahrwerken durch Rampen mit kleinen, maximal 8% betragenden Neigungen, erfolgt.
  • Zum anderen wird ein vom Beladungszustand unabhängiges, weitestgehend konstantes Einstiegsniveau mittels Niveauregulierung erreicht, womit ein Wegfall oder zumindest eine deutliche Reduktion der Rampenlandschaft im Fahrzeuginnenraum ermöglicht wird.
At present, three solution variants are used in vehicle concepts with conventional chassis technology with usual wheelbase and smallest wheel diameters of 500 mm in the worn, minimum permissible wheel diameter to achieve low entry heights in combination with wheelchair-friendly multifunctional surfaces:
  • On the one hand, an attempt is made to make the boarding heights on the vehicle greater or equal to 250 mm, which means that platform heights of around 250 mm are well coordinated so that the level compensation between the floor height directly at the entrance and the multi-functional areas to the floor height above the trolleys is achieved by means of ramps with small, maximum Inclinations of 8%.
  • On the other hand, a largely constant entry level that is independent of the loading condition is achieved by means of level regulation, which means that the ramp landscape in the Vehicle interior is made possible.

Nach einem weiteren bekannten Konzept werden Rampenlandschaften in das Fahrzeug eingeführt, die 8% bei weitem übersteigen, um die Höhendifferenz des Fußbodenniveaus im Fahrwerksmodul zu Multifunktionsflächen, unmittelbar angrenzend an die Fahrerkabine und von dort zur Einstiegskante, zu überwinden.According to another known concept, ramp landscapes are introduced into the vehicle, which exceed 8% by far in order to overcome the height difference of the floor level in the chassis module to multifunctional areas, immediately adjacent to the driver's cab and from there to the entrance edge.

Die Aufgabe der vorliegenden Erfindung besteht darin, die aus dem Stand der Technik bekannten Einstiegssituationen in 100% niederflurigen Multigelenksfahrzeugen insbesondere für Rollstuhlfahrer zu verbessern sowie einen rollstuhlfahrergerechten Multifunktionsbereich zur Verfügung zu stellen. Durch den erfindungsgemäßen Einzug eines Zwischenniveaus in herkömmlichen Multigelenksfahrzeugen wird eine rollstuhlfahrergerechte Multifunktionsfläche im Bereich hinter der Fahrerkabine zur Verfügung gestellt, welche durch ein niedrige Einstiegshöhe und einem breiten Einstiegsbereich charakterisiert ist.The object of the present invention is to improve the entry-level situations known from the prior art in 100% low-floor multi-articulated vehicles, in particular for wheelchair users, and to provide a multifunctional area suitable for wheelchair users. By moving an intermediate level into conventional multi-articulated vehicles according to the invention, a multifunctional area in the area behind the driver's cab that is suitable for wheelchair users is provided, which is characterized by a low entry height and a wide entry area.

Das horizontale Zwischenniveau weist dabei eine horizontale Fläche von rund 1,1 m2 auf und verfügt über Quer- und Längsrampen und einen Zwickelbereich, wobei die Rampen und der Zwickelbereich über Neigungen vom Niveau über den physischen Achsen in Richtung Zwischenniveau bzw. vom Zwischenniveau in Richtung Einstieg verfügen. Vorteilhaft weist das Zwischenniveau eine Fläche für einen überwiegend horizontalen Rollstuhlwendekreis von mindestens 1500 mm auf, wobei der Einstieg sowie der Zugangsweg zum Zwischenniveau über eine Breite von mindestens 1000 mm verfügen. Der überwiegende, horizontale Anteil der Fläche des Rollstuhlwendekreises an der Gesamtfläche des Wendekreises von 1500 mm Durchmesser beträgt 55,6%. Nach einem besonderen Merkmal der Erfindung ist vorgesehen, dass die maximale Rampenneigung des Zugangsweges vom Einstieg aus, quer zur Fahrtrichtung, d.h. der Querrampe, und in Fahrzeuglängsachse, d.h. der Längsrampe, maximal 7% bzw. 4° beträgt. Nach einem weiteren Merkmal ist vorgesehen, dass die maximale Rampenneigung des Zugangsweges vom Einstieg aus, quer zur Fahrtrichtung, d.h. der Querrampe, 7% bzw. 4° und in Fahrzeuglängsachse, d.h. der Längsrampe, maximal 5% bzw. 3° beträgt. Zusammen betragen die beiden Rampen, kleiner als 7% bzw. 4° Neigung betragend, 43,8% des Rollstuhlwendekreises von 1500 mm Durchmesser.The horizontal intermediate level has a horizontal area of approximately 1.1 m 2 and has transverse and longitudinal ramps and a gusset area, the ramps and the gusset area being inclined from the level above the physical axes in the direction of the intermediate level or from the intermediate level in the direction To get started. The intermediate level advantageously has a surface for a predominantly horizontal wheelchair turning circle of at least 1500 mm, the entrance and the access path to the intermediate level having a width of at least 1000 mm. The predominant, horizontal share of the area of the wheelchair turning circle of the total area of the turning circle of 1500 mm diameter is 55.6%. According to a special feature of the invention, it is provided that the maximum ramp inclination of the access path from the entrance, transversely to the direction of travel, ie the transverse ramp, and in the vehicle longitudinal axis, ie the longitudinal ramp, is a maximum of 7% or 4 °. According to a further feature, it is provided that the maximum ramp inclination of the access path from the entrance, transversely to the direction of travel, ie the transverse ramp, is 7% or 4 ° and in the vehicle longitudinal axis, ie the longitudinal ramp, is a maximum of 5% or 3 °. Together, the two ramps, less than 7% or 4 ° inclination, are 43.8% of the wheelchair turning circle of 1500 mm in diameter.

Weiter ist vorgesehen, dass der Rollstuhlwendekreis zu einem geringen Teil von den Flächen für die Quer- und Längsrampen durchdrungen wird, wobei dieser Durchdringungsbereich überwiegend Rampenneigungen von maximal 7% bzw. 4° umfasst, wobei der Durchdringungsbereich zu einem geringen Teil Rampenneigungen von maximal 25% bzw. 14° umfasst. Der Anteil dieser, größer als 7% aber jedenfalls kleiner 25% betragenden Teilfläche des Wendkreises an der Gesamtfläche des Wendekreises von 1500 mm Durchmesser beträgt ca. 0,6%. Derartige Neigungen sind dabei vorzugsweise im Einstiegsbereich vorgesehen. Vorteilhaft ist auch vorgesehen, dass die Einstiegshöhe im Bereich des Einstiegs kleiner 250 mm, vorzugsweise 200 bis 220 mm bei neuem Rad (maximaler Raddurchmesser) beträgt.It is also envisaged that the wheelchair turning circle to a small extent from the Areas for the transverse and longitudinal ramps are penetrated, this penetration area predominantly comprising ramp inclinations of a maximum of 7% or 4 °, the penetration area comprising a small part of ramp inclinations of a maximum of 25% or 14 °. The proportion of this partial area of the turning circle, which is greater than 7% but in any case less than 25%, of the total area of the turning circle of 1500 mm diameter is approximately 0.6%. Such inclinations are preferably provided in the boarding area. It is also advantageously provided that the entry height in the area of the entry is less than 250 mm, preferably 200 to 220 mm for a new wheel (maximum wheel diameter).

Durch die vorliegende Erfindung wird die Einrichtung eines für Rollstuhlfahrer uneingeschränkt nutzbaren Multifunktionsbereiches, unmittelbar angrenzend an die Fahrerkabine in 100% niederflurigen Multigelenksfahrzeugen in modularer Bauweise, mit einem unüblich niedrigen Einstiegsniveau unter 250 mm, vorzugsweise 200 mm, ermöglicht. Dabei wird eine völlig neuartige Einstiegssituation für Rollstuhlfahrer in Form einer Multifunktionsfläche vorgeschlagen, die unmittelbar hinter der Fahrerkabine eines 100% niederflurigen Gelenksfahrzeuges mit herkömmlicher Fahrwerkstechnik mit besonders niedrigen Einstiegshöhen von kleiner 250 mm über Schienenoberkante ohne Verwendung weiterer Einstiegshilfen wie Klapprampen oder Hubliften auskommt.The present invention enables the establishment of a multifunctional area which can be used without restriction for wheelchair users, directly adjacent to the driver's cab in 100% low-floor multi-articulated vehicles in a modular design, with an unusually low entry level below 250 mm, preferably 200 mm. A completely new entry situation for wheelchair users in the form of a multifunctional area is proposed, which works directly behind the driver's cabin of a 100% low-floor articulated vehicle with conventional chassis technology with particularly low entry heights of less than 250 mm above the top edge of the rail without the use of further entry aids such as folding ramps or lifting lifts.

Die Fig. 1 zeigt ein 100% niederfluriges Multigelenksfahrzeug unter Verwendung von herkömmlichen Fahrwerken mit üblichen Achsabständen, von Achsradsätzen sowie Losrädern auf Portalachsen mit unterschiedlichen Antriebskonzepten und Losrädern in Einzelradaufhängungen in unterschiedlichen Antriebskonzepten, wobei die geringsten Raddurchmesser (z.B. abgefahrener Zustand) 500 mm nicht unterschreiten und wie aus Fig. 2 ersichtlich, eine rollstuhlfahrergerechte Multifunktionsfläche 5 plus Zutrittsmöglichkeit durch Einstiegstüren 4 unmittelbar zwischen der erste Achse 3 und der Fahrerkabine 2 angeordnet ist.The Fig. 1 shows a 100% low-floor multi-articulated vehicle using conventional bogies with standard wheelbase, axle wheel sets and idler wheels on portal axles with different drive concepts and idler wheels in independent wheel suspensions in different drive concepts, whereby the smallest wheel diameter (e.g. worn condition) does not fall below 500 mm and how Fig. 2 It can be seen that a multifunctional area 5 suitable for wheelchair users plus the possibility of access through entrance doors 4 is arranged directly between the first axle 3 and the driver's cabin 2.

Die Einstiegshöhe an der Tür-Einstiegskante von ca. 200 mm, jedenfalls < 250 mm über Schienenoberkante (üSOK), soll Rollstuhlfahrern bei 100% niederflurigen Multigelenksfahrzeugen ein Betreten des Fahrzeuges bei besonders flachen Bahnsteigen oder sogar vom Schienenniveau aus unter Maßgabe des Raddurchmessers im Neuzustand ermöglichen. Die Multifunktionsfläche 5 wird wie in den Fig. 2 und Fig. 3 dargestellt, durch ein horizontales Zwischenniveau 5.1 gebildet, welches eine überwiegend horizontale Fläche aufweist. Weiter sind Quer- und Längsrampen 5.2, 5.3 vorgesehen, welche über Neigungen vom Niveau über den physischen Achsen in Richtung Zwischenniveau 5.1 bzw. vom Zwischenniveau 5.1 in Richtung Einstiegsbereich 4 verfügen. Das Zwischenniveau (5.1) umfasst eine Fläche von rund 1,1 m2 für einen überwiegend horizontalen Rollstuhlwendekreis von mindestens 1500 mm und der Einstiegsbereich 4 sowie der Zugangsweg zum Zwischenniveau 5.1 weist eine Breite von mindestens 1000 mm auf. Die maximalen Rampenneigungen des Zugangsweges vom Einstiegsbereich 4 aus, quer zur Fahrtrichtung, d.h. der Querrampe 5.2 sowie in Fahrzeuglängsachse, d.h. der Längsrampe 5.3 betragen maximal 7% bzw. 4°. Nach einer bevorzugten Ausführung der Erfindung gemäß den Fig.4 und 5 betragen die maximalen Rampenneigungen des Zugangsweges vom Einstiegsbereich aus, quer zur Fahrtrichtung, d.h. der Querrampe 5.2 7% bzw. 4° und in Fahrzeuglängsachse, d.h. der Längsrampe 5.3 maximal 5% bzw. 3°. Der Rollstuhlwendekreis kann zu einem geringeren Teil von den Flächen für die Quer- und Längsrampen 5.2, 5.3 durchdrungen sein, wobei dieser Durchdringungsbereich überwiegend Rampenneigungen von maximal 7% bzw. 4° umfasst. Der Durchdringungsbereich kann zu einem verschwindend geringen Teil auch einen Zwickelbereich 5.4 mit einer Rampenneigung von maximal 25% bzw. 14° umfassen, wobei derartige Neigungen vorzugsweise in Richtung des Einstiegsbereichs 4 vorgesehen sind, was aus der Fig. 5 deutlich wird.The entry height at the door entry edge of approx. 200 mm, at least <250 mm above the top edge of the rail (üSOK), is intended to enable wheelchair users to enter the vehicle on 100% low-floor multi-articulated vehicles on particularly flat platforms or even from the rail level in accordance with the wheel diameter when new , The multifunctional surface 5 is as in the Fig. 2 and Fig. 3 shown, formed by a horizontal intermediate level 5.1, which has a predominantly horizontal surface. Furthermore, transverse and longitudinal ramps 5.2, 5.3 are provided, which have inclinations from the level above the physical axes in the direction of intermediate level 5.1 or from intermediate level 5.1 in the direction of boarding area 4. The intermediate level (5.1) covers an area of around 1.1 m 2 for a predominantly horizontal wheelchair turning circle of at least 1500 mm and the entry area 4 and the access path to the intermediate level 5.1 have a width of at least 1000 mm. The maximum ramp inclinations of the access path from the entry area 4, transversely to the direction of travel, ie the transverse ramp 5.2 and in the vehicle longitudinal axis, ie the longitudinal ramp 5.3, are a maximum of 7% or 4 °. According to a preferred embodiment of the invention according to the Figure 4 and 5 The maximum ramp inclinations of the access path from the entry area are transverse to the direction of travel, ie the transverse ramp 5.2 7% or 4 ° and in the vehicle longitudinal axis, ie the longitudinal ramp 5.3 a maximum of 5% or 3 °. The wheelchair turning circle can to a lesser extent be penetrated by the areas for the transverse and longitudinal ramps 5.2, 5.3, this penetration area predominantly comprising ramp inclinations of a maximum of 7% or 4 °.
