[0002] High-speed multiple unit

[0003] The invention relates to a high-speed multiple unit with a maximum speed of more than 250 km / h, comprising a plurality of car bodies.

[0004] High-speed multiple units in Germany consist of a certain number of individual cars, each mounted on two bogies. For vehicles operating at speeds of 250 km / h and above, the traction equipment is located below the floor, requiring high-floor car bodies with a floor height of 1200 mm to 1250 mm.

[0005] High-speed rail travel on the German rail network is characterized by vehicles with 1200-1250 mm high floors stopping at platforms with a height of 760 mm. This requires passengers to climb two steps when boarding and disembarking. Wheelchair users must be assisted by staff and transported using a vehicle-mounted lift or a platform lift provided at the station. Autonomous boarding for wheelchair users is currently not possible on high-speed multiple units (>250 km / h).

[0006] Passengers have to climb two steps when boarding and disembarking. This takes time when changing passengers and is inconvenient for elderly people or those with luggage. Wheelchair users require staffed boarding assistance and cannot board independently or travel spontaneously because they must request assistance.

[0007] Based on this, the object of the invention is to provide a high-speed train that enables improved boarding for wheelchair users.

[0008] This problem is solved by the high-speed multiple unit of claim 1.

[0009] Advantageous embodiments and further developments are the subject of the respective subclaims. According to the invention, a high-speed multiple unit with a maximum speed of more than 250 km / h is provided. The high-speed multiple unit comprises a plurality of car bodies, wherein at least one car body is a low-floor car body and at least one car body is a high-floor car body.

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

[0011] The high-floor car body is a car body that has a floor height that is higher than the floor height of the low-floor car body.

[0012] Conversely, the low-floor car body has a floor height that is lower than the floor height of the high-floor car body.

[0013] The high-floor car body has the highest floor height of the high-speed multiple unit according to the invention and the low-floor car body has the lowest floor height of the high-speed multiple unit according to the invention.

[0014] The design according to the invention makes it possible for a part of the high-speed multiple unit according to the invention to have a low-floor car body that allows a person with limited mobility, such as a wheelchair user, to enter the train autonomously from a 760 mm platform.

[0015] Furthermore, in the area of ​​the high-floor car bodies, it is possible to arrange traction equipment in the underfloor area so that a high-speed multiple unit can be provided which has a maximum speed of more than 250 km / h, preferably more than 280 km / h, further preferably more than 300 km / h and in particular more than 330 km / h.

[0016] At such speed ranges, it was previously impossible to provide autonomous entry for people with limited mobility. The higher the maximum speed of a high-speed train, the greater the conflict between low entry and high speed, which the present invention resolves.

[0017] In the design of the high-speed multiple unit, each car body may have two bogies.

[0018] Accordingly, each car body has two separate bogies, which are assigned to only one car body.

[0019] In a further development of the high-speed multiple unit, it can further be provided that at least one car body is a center-floor car body.

[0020] The mid-floor car body is a car body that has a floor height that is higher than the lowest floor height of the low-floor car body.

[0021] The medium-floor car body is a car body that has a floor height that is lower than the floor height of the high-floor car body.

[0022] Preferably, the medium-floor vehicle body has a floor height that is below the floor height of the high-floor vehicle body and above the lowest floor height of the low-floor vehicle body.

[0023] The high-speed multiple unit may be designed with at least one car body as an NH transition car body with a low-floor section and a high-floor section. An NH transition car body is thus a low-floor / high-floor transition car body.

[0024] This provides an NH transition car body that provides a transition from a low-floor section to a high-floor section.

[0025] Furthermore, the high-speed multiple unit can provide for at least one car body to be a high-floor transition car body with a mid-floor section and a high-floor section. A high-floor transition car body is thus a mid-floor / high-floor transition car body.

[0026] This provides an MH transition car body that provides a transition from a mid-floor section to a high-floor section.

[0027] Furthermore, the high-speed multiple unit can provide for at least one car body to be a medium-low-floor transition car body with a mid-floor section and a low-floor section. An MN transition car body is thus a mid-floor / low-floor transition car body.

[0028] This provides an MN transition car body that provides a transition from a mid-floor section to a low-floor section.

[0029] It can further be provided that the high-speed multiple unit has a plurality of traction bogies, wherein the traction bogies are arranged on the at least one high-floor car body.

[0030] It is preferably provided that the traction bogies are arranged exclusively on the at least one high-floor wagon body.

[0031] Furthermore, it can be provided that the at least one low-floor car body is free of traction bogies.

[0032] Furthermore, it can be provided that the at least one central floor car body is free of traction bogies.

[0033] Furthermore, it can be provided that the at least one NH transition car body and / or the at least one MH transition car body and / or the at least one MN transition car body is free of traction bogies. If a car body is free of traction bogies, the floor height of the car body can be designed lower than in the case where a car body has a traction bogie.

[0034] In particular, the traction motors in the traction bogies have corresponding diameters for the required power, necessitating large wheels. The idea is now to arrange the traction equipment in the high-floor car bodies in such a way that the low-floor car bodies are free of traction equipment below the floor, and the floor can be lowered by using trailer bogies with smaller wheels. Using the example of a 400-meter-long train, 8 of the 22 entrances can be designed as low-level entrances and lowered by one or even two steps compared to a high-level entrance in the area of ​​a high-floor car body.

[0035] In an embodiment of the high-speed multiple unit, it can be provided that the high-speed multiple unit has a plurality of, preferably underfloor, traction units, wherein the, preferably underfloor, traction units are arranged on the at least one high-floor car body.

[0036] It is preferably provided that the, preferably underfloor, traction units are arranged exclusively on the at least one high-floor vehicle body.

[0037] In a further development of the high-speed multiple unit, it can be provided that at least one low-floor car body is free of, preferably underfloor, traction units.

[0038] Furthermore, it can be provided that the at least one NH transition car body and / or the at least one MH transition car body and / or the at least one MN transition car body is free of, preferably underfloor, traction units.

[0039] If a car body is free of underfloor traction units, the floor height of the car body can be lower than if the car body has an underfloor traction unit. Traction units include, for example, transformers and / or power converters.

[0040] In an advantageous development of the high-speed multiple unit, it can be provided that the at least one high-floor car body has a bogie center distance of 16000 mm to 18000 mm, preferably of 16500 mm to 17500 mm, in particular of 17000 mm.

[0041] This ensures that a relatively large bogie center distance is provided, which increases the dimensions of the high-floor car bodies and the associated space inside the car body.

[0042] In the design of the high-speed multiple unit, it can further be provided that the at least one low-floor car body has a bogie center distance of 13800 mm to 15800 mm, preferably of 14300 mm to 15300 mm, in particular of 14800 mm.

[0043] At least one low-floor car body has a shorter bogie center distance than the high-floor car body in order to achieve a corresponding internal width due to the narrower restriction profile of the infrastructure in the lower area.

[0044] Furthermore, the high-speed multiple unit can provide that the at least one central floor car body 12 has a bogie center distance D of 13800 mm to 15800 mm, preferably of 14300 mm to 15300 mm, in particular of 14800 mm.

[0045] At least one of the medium-floor car bodies has a shorter bogie center-to-center distance than the high-floor car body in order to achieve a corresponding internal width due to the narrower restriction profile of the infrastructure in the lower area.

[0046] In an embodiment, the high-speed multiple unit can further provide that the at least one NH transition car body and / or the at least one MH transition car body and / or the at least one MN transition car body has a bogie center distance of 13800 mm to 15800 mm, preferably of 14300 mm to 15300 mm, in particular of 14800 mm.

[0047] The at least one NH transition car body and / or the at least one MH transition car body and / or the at least one MN transition car body has a shorter bogie center distance than the high-floor car body in order to achieve a corresponding internal width due to the narrower restriction profile of the infrastructure in the lower area.

[0048] In an advantageous embodiment of the high-speed multiple unit, it can be provided that the high-speed multiple unit has at least one low-floor area, with a total low-floor length of 90,000 mm to 130,000 mm, preferably of 100,000 mm to 120,000 mm, further preferably of 105,000 mm to 115,000 mm, in particular of substantially 110,000 mm.

[0049] This design ensures that the high-speed train will meet all the requirements of a person with reduced mobility, such as a wheelchair user, but at the same time only part of the high-speed train will be low-floor.

[0050] The total low-floor length is the total length of all low-floor areas.

[0051] In a further development of the high-speed multiple unit, it can be provided that a plurality of low-floor car bodies and preferably at least one NH transition car body and / or at least one MN transition car body are arranged one behind the other in such a way that they form a first continuous low-floor area of ​​at least 100,000 mm, preferably of at least 105,000, in particular of at least 110,000 mm in length.

[0052] By forming a first continuous low-floor area, a continuous low-floor area is provided, allowing a person with limited mobility, such as a wheelchair user, to enjoy all the essential comfort features of a modern high-speed multiple unit. In a design of the high-speed multiple unit, it can be provided that at least one NH transition car body and / or at least one MN transition car body and / or preferably one low-floor car body are arranged one behind the other in such a way that they form a second continuous low-floor area of ​​at least 100,000 mm, preferably of at least 105,000 mm, in particular of at least 110,000 mm in length.

[0053] By creating a second continuous low-floor area, a second, continuous low-floor area is provided, which integrates additional functional features into the high-speed trainset. For example, the second continuous low-floor area can be designed in such a way that the needs of cyclists or train passengers with bicycles are accommodated in a separate area.

[0054] In one embodiment, for example, the second connected low-floor area can have a bicycle compartment.

[0055] In a further development of the high-speed multiple unit, it can be provided that the first continuous low-floor area and / or the second continuous low-floor area each have several low entrances to form redundant wheelchair entrances in the first continuous low-floor area and / or in the second continuous low-floor area.

[0056] In an embodiment of the high-speed multiple unit, it can be provided that the high-speed multiple unit has at least one high-floor area with a total high-floor length of at least 210,000 mm, preferably of at least 220,000 mm, further preferably of at least 230,000 mm, in particular of at least 240,000 mm.

[0057] This design allows a large portion of the high-speed train to be constructed according to the current design of a high-speed train with distributed traction. The total high-floor length is the sum of all high-floor sections.

[0058] In the design of the high-speed multiple unit, it can be provided that at least one high-floor car body and preferably at least one NH transition car body and / or at least one MH transition car body are arranged one behind the other in such a way that they form a first continuous high-floor area of ​​at least 100,000 mm, preferably of at least 105,000 mm, in particular of at least 110,000 mm in length.

[0059] This design ensures that a large part of the high-speed multiple unit can be constructed according to the previously common design of a high-speed multiple unit with distributed traction and that a first continuous high-floor area is created for passengers who are not restricted in their mobility, which implements all the usual comfort features and allows the corresponding division into a first and second carriage class.

[0060] In an advantageous development of the high-speed multiple unit, it can be provided that at least one high-floor car body and preferably at least one NH transition car body and / or at least one MH transition car body are arranged one behind the other in such a way that they form a second continuous high-floor area of ​​at least 100,000 mm, preferably of at least 105,000 mm, in particular of at least 110,000 mm in length.

[0061] This design ensures that a large part of the high-speed multiple unit can be constructed in accordance with the previously common design of a high-speed multiple unit with distributed traction and that a second continuous high-floor area is created for passengers who are not restricted in their mobility, which implements all the usual comfort features and allows the corresponding division into a first and second carriage class and is preferably spatially separated from the first continuous high-floor area.

[0062] It can further be provided that the first continuous high-floor area comprises an end car body and / or the second continuous high-floor area comprises an end car body. In a further development of the high-speed multiple unit, it can be provided that the high-speed multiple unit has at least one central floor area with a total central floor length of at least 25,000 mm, preferably at least 30,000 mm, further preferably at least 35,000 mm, in particular at least 40,000 mm.

[0063] This creates a level that, in terms of floor height, lies between the high-floor and low-floor areas. This makes it possible, for example, to arrange certain units below the floor in the underfloor area, while simultaneously maintaining only minimal height differences between the mid-floor area and the high-floor area, as well as between the mid-floor area and the low-floor area.

[0064] For example, a restaurant car or a car with catering facilities can be arranged in the central corridor area.

[0065] Furthermore, a central corridor entrance can be provided in the central corridor area, which allows ground-level access to the floor of the central corridor area.

[0066] In the design of the high-speed multiple unit, it can be provided that at least one central floor car body and preferably at least one MH transition car body and / or at least one MN transition car body are arranged one behind the other in such a way that they form a first continuous central floor area of ​​25,000 mm to 60,000 mm, preferably of 30,000 mm to 50,000 mm, further preferably of 35,000 mm to 55,000 mm, in particular of substantially 40,000 mm in length.

[0067] This provides a continuous central floor area, which makes it possible to provide certain comfort features of existing high-speed multiple units.

[0068] In an advantageous development of the high-speed multiple unit, it can further be provided that the first continuous low-floor area and / or the second continuous low-floor area is arranged between the first continuous high-floor area and the second continuous high-floor area. This ensures that a first and / or second low-floor area is arranged between the first continuous high-floor area and the second continuous high-floor area, so that a sufficiently large area is formed between the high-floor areas, which has a low floor to offer a high level of travel comfort to persons with impaired mobility.

[0069] In the design of the high-speed multiple unit, it can further be provided that the central floor area is arranged between the first continuous low-floor area and the second continuous low-floor area.

[0070] This makes it possible to integrate the central floor area between the first continuous low-floor area and the second continuous low-floor area using low-gradient ramps, so that it is easily accessible for people with impaired mobility.

[0071] In an advantageous development of the high-speed multiple unit, the at least one high-floor car body can have a floor height of 1150 mm to 1300 mm, preferably 1200 mm to 1250 mm. This allows traction bogies and traction units to be arranged in the underfloor area of ​​the at least one high-floor car body.

[0072] It can further be provided in the design of the high-speed multiple unit that the at least one first continuous and / or second continuous low-floor area, i.e. in particular the at least one low-floor car body, has a floor height of 760 mm to 900, preferably 810 to 900 mm, further preferably 830 mm to 880 mm and / or a floor height of 1050 mm to 1130 mm, preferably 1070 mm to 1130 mm, in particular 1100 mm.

[0073] In a first embodiment of the high-speed multiple unit, the at least one first continuous low-floor area and / or second continuous low-floor area, i.e. in particular the at least one low-floor car body, can have a floor height in the entrance areas, in particular the entrance floors, of 760 mm to 900 mm, preferably 810 to 900 mm, further preferably 830 mm to 880 mm. In the passenger areas, in particular the passenger floors, the floor height is 1050 mm to 1130 mm, preferably 1070 mm to 1130 mm, in particular 1100 mm. The floor height in the entire passenger areas is 1050 mm to 1130 mm, preferably 1070 mm to 1130 mm, in particular 1100 mm, so that both the aisle and the seats are on the same level.

[0074] Ramps are arranged between the entrance areas and the passenger areas, which bridge the height difference and are designed in accordance with TSI PRM (Technical Specification for Interoperability for Persons with Reduced Mobility).

[0075] Where necessary, these ramps are shallow enough to be used by wheelchair users.

[0076] In a second embodiment of the high-speed multiple unit, the at least one first continuous low-floor area and / or second continuous low-floor area, i.e. in particular the at least one low-floor car body, can have a floor height of 760 mm to 900 mm, preferably 810 to 900 mm, furthermore preferably 830 mm to 880 mm. The entrance areas, in particular the entrance floors, the passenger areas, in particular the passenger floors, the floor height in the aisle is 760 mm to 900 mm, preferably 810 to 900 mm, furthermore preferably 830 mm to 880 mm. The seats are arranged at a floor height of 1050 mm to 1130 mm, preferably 1070 mm to 1130 mm, in particular 1100 mm, which is higher than the aisle, so that the aisle and the seats are arranged at different heights.

[0077] In the design of the high-speed multiple unit, it can be provided that the at least one central floor car body has a floor height of 1050 mm to 1130 mm, preferably of 1070 mm to 1130 mm, in particular of 1100 mm.

[0078] In a design of the high-speed multiple unit, it can be provided that the at least one low-floor car body and / or the at least one NH transition car body and / or the at least one MH transition car body and / or at least one MN transition car body have a low entrance with a door threshold height of 800 mm to 820 mm. The door thresholds at the low entrances have a height of 800 mm to 820 mm. Furthermore, the low entrances have a sliding step located 20 mm to 30 mm above a 760 mm platform, i.e., at a height of 820 mm to 850 mm.

[0079] From the door threshold, a height gain to a floor level of 760 mm to 900, preferably 810 to 900 mm, further preferably 830 mm to 880 mm in the entry area, in particular to the entry floor, is achieved by means of a flat ramp.

[0080] This allows wheelchair users to board and disembark the high-speed train independently from a 760mm high platform. Passengers with large luggage or bicycles can board and disembark much more easily, speeding up passenger boarding and disembarking and significantly increasing comfort.

[0081] The high-speed multiple unit may further provide that the at least one high-floor car body has at least one high entrance with one or two steps.

[0082] The high-speed train is preferably a single-deck train.

[0083] All heights refer to the level of the track, i.e. the point at which the wheels of the high-speed train are in contact with the track.

[0084] The invention will be explained below using several embodiments with reference to the drawings.
