Description

[0001] The invention relates to a high-speed multiple unit train with a maximum speed of more than 250 km / h, comprising a plurality of intermediate car bodies and two end car bodies.

[0002] High-speed multiple units in Germany consist of a certain number of individual cars, each mounted on two bogies. For vehicles designed for speeds above 250 km / h, the traction equipment, along with the traction bogies, is located under the floor, which has thus far necessitated consistently high-floor car bodies with a floor height of 1200 mm to 1250 mm.

[0003] High-speed rail services in Germany are characterized by the fact that trains with floors 1200-1250 mm high stop at platforms 760 mm high. This means passengers have to overcome two steps when boarding and alighting. Wheelchair users must be assisted by staff and transported using a platform lift either on the train or one provided at the station. Independent boarding for wheelchair users is not yet possible on high-speed trains (over 250 km / h).

[0004] Passengers have to climb two steps to board and alight. This takes time during passenger exchange and is difficult for elderly people or those with luggage. Wheelchair users require staff assistance and cannot board independently or travel spontaneously because they have to request assistance in advance.

[0005] Patent EP 2 179 905 B1 discloses a high-speed multiple unit with a maximum speed of more than 250 km / h, comprising a plurality of intermediate car bodies and two end car bodies, wherein at least one first intermediate car body has two terminal traction bogies and at least one second intermediate car body has two Jacobs running bogies, and wherein the high-speed multiple unit has a plurality of traction units.

[0006] Based on this, the invention aims to provide a high-speed train that enables improved boarding.

[0007] This problem is solved by the high-speed train of claim 1.

[0008] Advantageous designs and further developments are the subject of the respective sub-claims.

[0009] According to the invention, a high-speed multiple unit train with a maximum speed of more than 250 km / h is provided, comprising a plurality of intermediate car bodies and two end car bodies. At least one first intermediate car body has two end traction bogies, and at least one second intermediate car body has two Jacobs bogies. At least one third intermediate car body has two end running bogies. The high-speed multiple unit train has a plurality of traction units, wherein the traction units are arranged on the at least one third intermediate car body, and the at least one first intermediate car body is free of traction units.

[0010] Preferably, the maximum speed of the high-speed train is more than 280 km / h, more preferably more than 300 km / h, and in particular more than 330 km / h.

[0011] The inventive design of the second intermediate car body with two Jacobs bogies makes it possible for the high-speed multiple unit according to the invention to have a low-floor design in this second intermediate car body. This allows for easier boarding due to a smaller height difference to the platform. If a car body is free of traction bogies, the floor height of the car body can be designed to be lower than if a car body has a traction bogie.

[0012] By positioning the bogies between the car bodies, the floor can be lowered to its maximum level in the aisle of the seating area, eliminating the need for ramps or changes in height. This allows for quick and convenient passenger boarding and alighting. It also enables independent boarding for passengers with reduced mobility (e.g., wheelchair users, strollers, bicycles, etc.). This design is implemented for all classes (here, 1st and 2nd class), thus preventing discrimination against different passenger groups.

[0013] In addition to this optimization of ride comfort, the heavily stressed drive and braking technology is distributed in the center of the train, located in the underfloor area, in a proven manner. This increases the train's cost-effectiveness over its entire service life and allows existing infrastructure to continue to be used for maintenance.

[0014] Furthermore, by designing at least one intermediate car body with two terminal traction bogies, it is possible to create a very efficient train with distributed traction, which can achieve correspondingly high maximum speeds as a high-speed multiple unit.

[0015] In particular, the traction motors in the traction bogies have correspondingly large diameters to meet the required power output, necessitating large wheels. The idea is to arrange the traction bogies in at least one of the intermediate car bodies, so that at least one other intermediate car body is free of traction bogies underneath, allowing the floor to be lowered by using Jacobs bogies with smaller wheels.

[0016] Previously, it was not possible to provide autonomous boarding for people with reduced mobility at such speeds. The higher the maximum speed of a high-speed train, the greater the conflict between low-level boarding and high speed, which is resolved by the invention.

[0017] This design ensures that a large part of the high-speed train can be built according to the previously common design of a high-speed train with distributed traction, which at the same time has one or more low-floor areas in the area of ​​the Jacobs running bogies.

[0018] According to the invention, at least one, preferably every third, intermediate car body has two terminal running bogies.

[0019] Accordingly, at least one, preferably every third, car body has two separate bogies that are assigned to exactly one car body.

[0020] This makes it possible to achieve high wheel loads, since each car body has two separate bogies and correspondingly longer car bodies can be used, compared to Jacobs bogies.

[0021] In the design of the high-speed train, it may be provided that the end car bodies are free of traction bogies and / or free of traction units.

[0022] This means that the end car bodies are only slightly restricted with regard to any installation space limitations.

[0023] In the design of the high-speed train, it may be provided that the end car bodies each have a terminal running bogie and a Jacobs running bogie.

[0024] This makes it possible to design the end car bodies with a low floor.

[0025] In the design of the high-speed train, it may be provided that all Jacobs bogies of the high-speed train are Jacobs running bogies.

[0026] This allows the Jacobs bogies to be designed in a particularly compact way, which in the cars with Jacobs running bogies allows for a design as a low-floor car body.

[0027] In the design of the high-speed multiple unit, it may be provided that at least a fourth intermediate car body has a Jacobs running bogie and a terminal running bogie.

[0028] This makes it possible to create a low-floor area and at least one high-floor area in at least a fourth intermediate car body.

[0029] In the embodiment of the high-speed train, it can be provided that at least one first intermediate car body is a high-floor car body and preferably has a floor height of 1150mm to 1300mm, and further preferably of 1200mm to 1250mm.

[0030] This makes it possible to arrange traction equipment in the underfloor area of ​​at least one intermediate car body, so that a high-speed train can be provided which has a maximum speed of more than 250 km / h, preferably more than 280 km / h, and further preferably more than 300 km / h, in particular more than 330 km / h.

[0031] By designing at least one intermediate car body as a high-floor car body, it is possible, for example, to arrange certain assemblies below the floor in the underfloor area.

[0032] In the embodiment of the high-speed train, it can be provided that at least one second intermediate car body is a low-floor car body and preferably has a floor height of 760mm to 900mm, preferably 810mm to 900mm, and further preferably 830mm to 880mm.

[0033] Lowering the floor and thus providing level boarding significantly increases passenger exchange speed. This allows for more seats per train length. Boarding comfort is also improved, enhancing customer friendliness. Both of these factors increase the overall efficiency of the train concept. Furthermore, the legal requirement for greater inclusion is met by enabling fully autonomous boarding of the passenger-reducing carriages (PRM). These advantages are achieved without compromising operational performance or wear and tear, as the major components remain distributed under the floor, and the evolutionary developments of recent decades are fully utilized for economic optimization.

[0034] By designing at least one second intermediate car body as a low-floor car body, it is possible to achieve simplified entry via a smaller or no height difference to the platform.

[0035] This makes it possible to provide a high-speed train with a maximum speed of more than 250 km / h, preferably more than 280 km / h, and preferably more than 300 km / h, in particular more than 330 km / h, while simultaneously allowing easy boarding.

[0036] Previously, it was not possible to provide autonomous boarding for people with reduced mobility at such speeds. The higher the maximum speed of a high-speed train, the greater the conflict between low-level boarding and high speed, a conflict that is resolved here.

[0037] In the design of the high-speed train, it can be provided that at least one third intermediate car body is a high-floor car body and preferably has a floor height of 1150mm to 1300mm, and further preferably of 1200mm to 1250mm.

[0038] In at least one third intermediate car body, it is thus possible to arrange traction equipment in the underfloor area, so that a high-speed train can be provided which has a maximum speed of more than 250km / h, preferably more than 280km / h, and further preferably more than 300km / h, in particular more than 330km / h.

[0039] By constructing at least one third intermediate car body as a high-floor car body, it is possible, for example, to arrange certain assemblies below the floor in the underfloor area.

[0040] In the embodiment of the high-speed train, it can be provided that the at least one fourth intermediate car body is a transition car body, which has a high-floor section, preferably with a floor height of 1150mm to 1300mm, and further preferably of 1200mm to 1250mm, and which has a low-floor section, preferably with a floor height of 760mm to 900mm, and further preferably of 810mm to 900mm, in particular of 830mm to 880mm.

[0041] This creates a car body that allows a transition between the low-floor and high-floor sections. This makes it possible to create a transition between exclusively high-floor and exclusively low-floor car bodies.

[0042] In an advantageous further development of the high-speed train, it can be provided that a ramp is formed between the high-floor section and the low-floor section of at least one fourth intermediate car body.

[0043] This makes it possible for at least one low-floor area to be connected to the high-floor area by means of ramps with a slight gradient, so that it is easily accessible for people with impaired mobility.

[0044] The ramps that bridge the height difference are designed in accordance with TSI PRM (Technical Specification for Interoperability for “Persons with Reduced Mobility”).

[0045] Where necessary, these ramps are so shallow that they can be used by wheelchair users.

[0046] In the design of the high-speed train, it may be provided that at least one fourth intermediate car body is a low-floor entry car body with at least one low-floor area and at least one low-floor entry.

[0047] This eliminates the need for a step to bridge the height difference between the platform and the low-floor entrance.

[0048] In the design of the high-speed train, it may be provided that the end car bodies are low-floor car bodies and preferably each have at least one low-floor entrance.

[0049] This results in the end car bodies being designed as low-floor car bodies, making it possible to integrate them into a low-floor area.

[0050] This also means that no step needs to be provided to create a height difference between the platform and the low-floor entrance.

[0051] In the design of the high-speed train, it may be provided that at least one second intermediate car body is a low-floor car body, and preferably has at least one low-floor entrance.

[0052] This makes it possible to integrate at least one second intermediate car body into a low-floor area.

[0053] This eliminates the need for a step to bridge the height difference between the platform and the low-floor entrance.

[0054] By creating a low-floor entrance, a level entry is provided from the platform edge, enabling comfortable and independent boarding for passengers with reduced mobility (e.g. wheelchair users, strollers, bicycles, etc.).

[0055] In the design of the high-speed train, it can be provided that at least one low-floor entrance has a door sill height of 750mm to 870mm, preferably 780mm to 840mm, and further preferably 800-820mm.

[0056] This eliminates the need for a step to bridge the height difference between the platform and the low-floor entrance.

[0057] This improves boarding comfort, which in turn enhances customer friendliness. Both of these factors increase the efficiency of the high-speed train. Furthermore, the legislative requirement for greater inclusion is met by enabling fully autonomous boarding of the PRM trains.

[0058] In the design of the high-speed train, it may be provided that the traction bogies are arranged exclusively on at least one first intermediate car body.

[0059] This eliminates the need for corresponding adaptations to integrate traction bogies onto car bodies that differ from at least the first intermediate car body.

[0060] In the embodiment of the high-speed multiple unit, it may be provided that the high-speed multiple unit has a plurality of underfloor traction units, wherein the underfloor traction units are arranged on the at least one third intermediate car body and / or the at least one first intermediate car body is free of underfloor traction units and / or the at least one second intermediate car body and / or the at least one fourth intermediate car body is free of, preferably underfloor, traction units.

[0061] This ensures that only the third intermediate car body has traction units and is adapted accordingly.

[0062] If a car body is free of underfloor traction units, the floor height of the car body can be designed lower than if a car body has an underfloor traction unit.

[0063] Traction units include, for example, transformers and / or power converters.

[0064] In the design of the high-speed train, it can be provided that at least one, preferably every, third intermediate car body with traction units is arranged adjacent to the at least one first intermediate car body with terminal traction bogies.

[0065] This ensures that the traction units are located in close proximity to the traction bogies.

[0066] In addition to this optimization of ride comfort, the heavily stressed drive and braking technology is distributed across the underfloor area in the center of the high-speed train. This increases the train's cost-effectiveness over its entire service life and allows existing infrastructure to continue to be used for maintenance.

[0067] In the design of the high-speed train, it may be provided that the high-speed train has at least one continuous high-floor area extending over at least four, preferably at least five, further preferably at least six, in particular at least seven, further in particular at least eight, intermediate car bodies.

[0068] This design ensures that a large part of the high-speed train can be built in a modified form according to the previously common design of a high-speed train with distributed traction, and that a continuous high-floor area is provided for passengers who are not restricted in their mobility, which realizes all the usual comfort features and allows the corresponding division into a first and second class.

[0069] For example, a restaurant car or a car body designed as a meeting place can be located in the high-floor area.

[0070] This provides a continuous high-floor area, making it possible to provide certain comfort features of existing high-speed multiple units.

[0071] In the design of the high-speed train, it can be provided that the high-speed train has at least one, preferably two, continuous low-floor area(s) which extends over at least three, preferably at least four, further preferably at least five, in particular at least six, intermediate car bodies and / or end car bodies.

[0072] This design ensures that the high-speed train meets all the requirements of people with reduced mobility, such as wheelchair users, cyclists, or families with children, while at the same time only at least one, preferably two, sections of the high-speed train are low-floor. The remaining section can be high-floor.

[0073] The design of the high-speed train may include at least one second intermediate car body and / or at least one fourth intermediate car body, each with at least one family toilet and / or large-capacity toilet and / or at least one bicycle parking area and / or at least one family and toddler area.

[0074] This ensures that the requirements for toilets for families with children or people with reduced mobility are met in a separate area. The integration of at least one family toilet and / or a large-capacity toilet into at least one second intermediate car body and / or at least one fourth intermediate car body is particularly advantageous, especially if these are low-floor.

[0075] This also ensures that the needs of cyclists and train passengers with bicycles are met in a separate area. The integration of at least one bicycle parking area into at least one second intermediate car body and / or at least one fourth intermediate car body is particularly advantageous, especially if these are low-floor.

[0076] This also ensures that the needs of families with children are met in a separate area. The integration of at least one family and toddler area into at least one second and / or at least one fourth intermediate car body is particularly advantageous, especially if these are low-floor.

[0077] A low-floor car body has the lowest floor height of the high-speed train.

[0078] A high-floor car body is a car body that has a floor height that is higher than the floor height of a low-floor car body.

[0079] The high-speed train is preferably a single-level train.

[0080] All heights refer to the level of the track, i.e., the point where the wheels of the high-speed train are in contact with the track.
