[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 have a certain number of individual cars, each mounted on two bogies. In vehicles designed for speeds above 250 km / h, the traction equipment is arranged underfloor along with the traction bogies, which previously required 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 difficult for older people or those with luggage. Wheelchair users require a staffed boarding aid 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 multiple unit that enables improved boarding.

[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, at least one of which is a mid-floor car body.

[0010] Preferably, the maximum speed is more than 280 km / h, further preferably more than 300 km / h, in particular more than 330 km / h.

[0011] The mid-floor car body has a floor height that is lower than the floor height of a previous high-floor car body (e.g. 1200mm to 1250mm).

[0012] The design according to the invention makes it possible for a large part of the high-speed multiple unit according to the invention to have a central floor car body, which allows simplified entry via a smaller height difference to the platform.

[0013] In addition, it is possible to arrange traction equipment in the underfloor area of ​​the central floor car bodies 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, in particular more than 330 km / h.

[0014] At such speed ranges, it was previously impossible to provide autonomous entry for people with limited mobility. The higher the top speed of a high-speed train, the greater the trade-off between low entry and high speed, which the present invention resolves.

[0015] By providing central floor car bodies and the resulting lowering of the vehicle structure compared to previous high-speed trains, boarding is no longer two-step but a maximum of one-step.

[0016] By providing central floor car bodies, it is possible, for example, to arrange certain units below the floor in the underfloor area, while at the same time having only small height differences between the central floor area and existing platforms.

[0017] 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.

[0018] In the design of the high-speed multiple unit, it can be provided that at least one car body is a low-floor entry car body with at least one low-floor area and at least one low-floor entry.

[0019] This creates a level entrance at the platform edge, which makes it possible for passengers with limited mobility (e.g. wheelchair users, strollers, bicycles, etc.) to board comfortably and independently.

[0020] At the same time, however, there are only small differences in height between the mid-floor area and the low-floor area.

[0021] The low-floor entry car body has the lowest floor height of the high-speed multiple unit according to the invention.

[0022] The mid-floor car body is a car body that has a floor height that is higher than the floor height of a low-floor entry car body.

[0023] In an advantageous development of the high-speed multiple unit, it can be provided that at least one center-floor car body, preferably two center-floor car bodies, is / are an end car body.

[0024] This allows the end car bodies to be designed with a center-floor layout, making it possible to integrate them into a center-floor area. In the design of the high-speed multiple unit, each car body can be provided with two bogies, preferably at the end.

[0025] Accordingly, in the case of terminal bogies, each car body has two separate bogies, which are assigned to exactly one car body.

[0026] This makes it possible to realize high wheel loads, since two separate bogies are provided for each car body and correspondingly longer car bodies can be used than is possible with Jakobs bogies.

[0027] In an advantageous development of the high-speed multiple unit, it can be provided that the at least one central floor car body has at least one central floor entrance with a single step.

[0028] The single-step entry combined with ground-level entrances significantly increases passenger boarding speed. This improves boarding comfort, which enhances customer friendliness. Both of these factors increase the cost-effectiveness of the high-speed train. Furthermore, the legislative demand for greater inclusion is met by enabling fully autonomous PRM boarding.

[0029] 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 950 mm to 1130 mm, preferably of 1000 mm to 1130 mm, further preferably of 1070 mm to 1130 mm, in particular of 1100 mm.

[0030] This makes it possible to provide only a single step to overcome the height difference between the platform and the central floor entrance. In an advantageous development of the high-speed multiple unit, the low-floor entrance car body can be provided with at least one central floor area, with a ramp formed between the low-floor area and the central floor area.

[0031] This makes it possible to connect at least one low-floor area to the central floor area using ramps with a low gradient, so that it is easily accessible for people with impaired mobility.

[0032] The ramps that bridge the height difference are designed according to TSI PRM (Technical Specification for Interoperability for Persons with Reduced Mobility).

[0033] Where necessary, these ramps are shallow enough to be used by wheelchair users.

[0034] In the design of the high-speed multiple unit, it can be provided that the at least one low-floor entry car body in the low-floor area 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 in the middle floor area of ​​950 mm to 1130 mm, preferably 1000 mm to 1130 mm, further preferably 1070 mm to 1130 mm, in particular 1100 mm.

[0035] This makes it possible that only a single step needs to be provided to overcome a height difference between the platform and the mid-floor entrance and no step needs to be provided to achieve a height difference between the platform and the low-floor entrance car.

[0036] In an advantageous development of the high-speed multiple unit, it can be provided that the low-floor entrance has a door threshold height of 750 mm to 870 mm, preferably 780 mm to 840 mm, further preferably 800-820 mm.

[0037] This eliminates the need to provide a step to create a height difference between the platform and the low-floor entry car. In a design of the high-speed multiple unit, the high-speed multiple unit may have a plurality of traction bogies, with the traction bogies preferably being arranged exclusively on the at least one mid-floor car body.

[0038] This eliminates the need for adaptations to car bodies that differ from mid-floor car bodies (such as low-floor entry car bodies).

[0039] In an advantageous development of the high-speed multiple unit, it can be provided that the high-speed multiple unit has a plurality of running bogies, wherein running bogies are arranged on the at least one low-floor entry car body.

[0040] This ensures that no traction bogies, especially traction motors, are located under the low-floor entry car bodies.

[0041] In the design of the high-speed multiple unit, it can be provided that at least one low-floor entry car body is free of traction bogies.

[0042] If a car body is free of traction bogies, the floor height of the car body can be made lower than in the case where a car body has a traction bogie.

[0043] In particular, the traction motors in the traction bogies have corresponding diameters for the required power, necessitating large wheels. The idea now is to arrange the traction equipment in the center-floor car bodies in such a way that low-floor entry car bodies are free of traction bogies below the floor, and the floor can be lowered by using trailer bogies with smaller wheels.

[0044] Preferably, the traction bogies are arranged exclusively on the at least one center-floor car body. In an advantageous development of the high-speed multiple unit, it can be provided that, in addition to the at least one center-floor car body with traction bogies, at least one center-floor car body has trailer bogies.

[0045] 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 mid-floor car body and / or the at least one low-floor entry car body is free of, preferably underfloor, traction units.

[0046] If a car body is free of underfloor traction units, the floor height of the car body can be designed lower than in the case where a car body has an underfloor traction unit.

[0047] Traction units include, for example, transformers and / or power converters.

[0048] In the design of the high-speed multiple unit, it can be provided that a centrally located car body with traction units is arranged adjacent to a centrally located car body with traction bogies.

[0049] This ensures that the traction units are arranged in close proximity to the traction bogies.

[0050] In an advantageous development of the high-speed multiple unit, it can be provided that at least one central floor car body with traction units is free of traction bogies.

[0051] This ensures that sufficient installation space is available to accommodate the other required units or assemblies of the mid-floor car body in the underfloor area, in addition to the traction units. In the design of the high-speed multiple unit, it can be provided that at least one end car body, preferably the two end car bodies, is / are free of traction units and / or traction bogies.

[0052] This ensures that there are fewer space-related restrictions when designing at least one end car body.

[0053] In an advantageous development of the high-speed multiple unit according to one of the preceding claims, characterized in that the at least one centrally located car body and / or the at least one low-floor entry car body has a bogie center-to-center distance of 14000 mm to 16800 mm, preferably of 14500 mm to 16300 mm, in particular of 15000 mm to 15800 mm.

[0054] This provides a bogie center-to-center distance that is dimensioned in such a way that it is suitable for both the mid-floor car body and the low-floor car body.

[0055] In the design of the high-speed multiple unit, it can be provided that the high-speed multiple unit has at least one continuous central floor area which extends over at least three, preferably at least four, further preferably at least five, in particular at least six, further in particular at least seven, central floor car branches.

[0056] This design ensures that a large part of the high-speed multiple unit can be built in a modified form corresponding to the previously common design of a high-speed multiple unit with distributed traction and that a continuous central 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 class carriage.

[0057] For example, a restaurant car or a car body designed as a meeting place can be located in the center floor area. This creates a continuous center floor area, making it possible to provide certain comfort features of existing high-speed multiple units.

[0058] Furthermore, a central floor entrance can be provided in the central floor area, allowing level access to the floor of the central floor area. This makes it possible to move heavy loads, for example, for the on-board restaurant, into the vehicle as easily as possible.

[0059] 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.

[0060] This makes it possible to move heavy loads, e.g. for the on-board restaurant, into the vehicle as easily as possible.

[0061] In an advantageous development of the high-speed multiple unit, it can be provided that the low-floor area of ​​the at least one low-floor entry car has a length which is smaller than the pivot pin distance of the low-floor entry car.

[0062] This makes it possible to provide a low-floor area without any special adaptation of the bogies or the car body ends, compared to the bogies and car bodies of the medium-floor cars.

[0063] In the design of the high-speed multiple unit, it can be provided that the high-speed multiple unit has at least one, preferably two, further preferably three, in particular four, low-floor entry car bodies.

[0064] This design ensures that the high-speed train meets all the requirements of people with limited mobility, such as wheelchair users, cyclists, or families with children, while at the same time only a small portion of the high-speed train will be low-floor. In an advantageous development of the high-speed train, at least one low-floor entry car body features at least one family restroom and / or open-plan restroom.

[0065] This ensures that the toilet needs of families with children or people with limited mobility are met in a separate area. The integration of at least one family toilet and / or open-plan toilet into at least one low-floor entry car is particularly advantageous.

[0066] In the design of the high-speed multiple unit, the at least one low-floor entry car body has at least one driving position area.

[0067] This ensures that the needs of cyclists or train passengers with bicycles are met in a separate area. The integration of at least one bicycle parking area into at least one low-floor entry car is particularly advantageous.

[0068] In an advantageous development of the high-speed multiple unit, the at least one low-floor entry car body has at least one family and toddler area.

[0069] This 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 low-floor entry car is particularly advantageous.

[0070] In a further development of the high-speed multiple unit, it can be provided that the at least one low-floor entrance car body has redundant low-floor entrances in the low-floor area on a respective side of the low-floor entrance car body.

[0071] The high-speed train is preferably a single-level train. 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.
