Description

Modular rail vehicle with modules of different widths

The invention relates to a rail vehicle with articulated interconnected

Car body modules.

Modern rail vehicles, in particular trams, are widely used in

Modular construction produced, mostly in low-floor technology. A rail vehicle in

Modular design is described for example in EP 0548044. The modules are connected by joints, which is why such vehicles are also referred to as Multigelenksfahrzeuge.

In general, there are modular rail vehicles, also referred to as modular rail vehicles, chassis modules and other modules disposed between the landing gear modules, such as the chassis modules. Litter or salon modules, and further Vorbaumodulen which are arranged at the beginning and at the end of the vehicle.

If modular rail vehicles in existing, older railway networks

(Stock networks) are to be used, where so far, for example, 2.2 m or 2.3 m wide, non-modular rail vehicles were in use, resulting from the narrow car body width no space-optimized seating options in the interior of the vehicle.

An object of the present invention is to provide a rail vehicle, which allows better use of the interior with seats and can be used in existing networks.

The problem is solved by a rail vehicle according to claim 1. advantageous

Embodiments are described in the subclaims.

Specified by the invention, a rail vehicle, comprising

at least a first body module,

at least a second carbody module,

wherein the first body module and the second body module are hinged together,

wherein the width of the first car body module is greater than the width of the second car body module. The width of a car body module is measured transversely to the longitudinal axis of the car body module, in particular exactly perpendicular to the longitudinal axis.

A "car body module" is also referred to below as "module".

A modular rail vehicle according to the invention allows in the wider first module a larger number of seats transversely to the car longitudinal direction and thereby a larger number of seats compared to an equally long rail vehicle, which consists only of modules with a smaller width than the width of the first module. If in existing networks only modules with a smaller width, for example, 2.2 m or 2.3 m width, are used, then in such modules per row of seats only a 2 + 1 seating with sufficient aisle width possible, i. two side-by-side seats and another seat separated by a corridor from the other two seats. Accordingly, the second body module may include rows of seats having a first pair of juxtaposed seats and a single seat, the pair of seats being separated from the single seat by a walkway.

In the vehicle according to the invention, for example, a 2 + 2 seating per row is possible in the broader first module, i. two juxtaposed seats and again two juxtaposed seats, which are separated by a corridor from the other two seats. In other words, the first body module may therefore comprise rows of seats having a first pair of juxtaposed seats and a second pair of juxtaposed seats, the pairs of seats being separated by a walkway. For example, the wider first module has a width of

2.4 m.

The width ratio of first to second module is preferably 1, 03 to 1 to 1, 2 to 1. The width is measured at the widest point of the respective module if the module is not rectangular.

The aspect ratio of the first to the second module is preferably 1.3 to 1 to

2.5 to 1.

The distance between the modules is preferably 0.7m to 1.5m.

Due to the varying width of the modules in the vehicle according to the invention is a very good utilization of the clearance gauge in tight bends possible without the Clearance gauge is exceeded. The clearance gauge is the profile, which on all sides, measured from the track, may not be exceeded to z. As in multi-track operation or bottlenecks possible collisions safely exclude. The clearance gauge is determined for the vertical transverse plane of the guideway. The envelope, when viewed from above the track, describes the limit that must not be exceeded by the rail vehicle. The envelope determined longitudinally along the track intersects the gauge in the plane transverse to the track.

Furthermore, the rail vehicle according to the invention with different widths is very easy to manufacture. Different width modules can be made individually and these can then be hinged to form a complete vehicle.

Preferably, in at least a portion of the rail vehicle, the first

Car body modules and the second car body modules arranged alternately, more preferably, the entire rail vehicle of alternating first and second

Assembled modules. However, it is possible to connect two or more first modules directly to one another within the rail vehicle and / or to connect two or more second modules directly to one another. In addition to the first and the second module, further modules may be present which have a greater width than the first module and a width other than the second module. Furthermore, one or two end modules or

Head modules may be provided. An end or head module may have the width of the first module, in which case it is a special case of the first module or the width of the second module, in which case it is a special case of the second module. The terms "first module" and "second module" refer to a different width, not the function or location of a module within the rail vehicle.

In particular, the first vehicle body module and the second vehicle body module have a rectangular or substantially rectangular plan, whereby they are particularly easy to manufacture. If an end module is a special case of a first or second module, then the end module may deviate from the rectangular plan to the outer end of the module. The end module then preferably has one

rectangular portion on and a portion which tapers towards the outer end of the module.

The function of the modules is not limited in principle. The first as the second module may be, for example, a landing gear module, a bogie module or a salon module. A salon module is a module without suspension or bogie that is between Chassis modules / bogie modules is arranged. The first wide body module preferably has a chassis or a bogie, so is a suspension module or bogie module. The arrangement of a chassis / bogie on the first module is advantageous due to its greater width. In a landing gear, the wheels do not rotate at all as compared to a bogie or at a smaller maximum angle relative to the carbody.

In one embodiment, a bellows or bellows is arranged between the first vehicle body module and the second vehicle body module. Due to the different width of the first and second module, the bellows or bellows on the inside of the curve is less compressed when cornering than with the same module width and the same distance between the modules and the same initial length of the bellows or

Wave bellows in straight aligned condition. Differently wide modules come in an angular position of both modules in the edge area less close than equal width modules. Bellows and corrugated bellows differ in shape and / or in production, with bellows and corrugated bellows in particular being sewn differently and / or having different seam shapes.

In a variant of the embodiment described above, the side walls of the bellows or bellows on the side of the first car body module have a greater distance from each other than on the side of the second car body module. In other words, the side walls of the bellows or bellows run towards one another in the direction from the first module to the second, narrower module. The side walls are thus tapered when viewed from above or, in other words, funnel-shaped. Even with this shape, the bellows or bellows on the inside of the curve is less compressed than the same module width and the same distance of the modules in the straight-aligned state. The conical shape of the bellows or bellows also has a positive effect on the bellows kinematics, since the individual waves or wrinkles move better and scrub less to each other. In addition, with the funnel shape, the passenger flow can be influenced. In a more specific variant, vehicle doors are located in the second, narrower modules and not in the first, wider modules. Of the

funnel-shaped bellows narrows in the direction of the second module and thus towards the door.

Passengers in the first module are intuitively indicated by the funnel shape, which is preferably a light but noticeable funnel shape, the direction to the door.

The type of rail vehicle is not limited in itself. Preferably that is

Rail vehicle a light rail vehicle, especially a tram. The invention will be described below with reference to exemplary embodiments. Show it

Shown are the end module 2 as the first module, the salon module 3 as a second module and the landing gear module 4 as a further first module. Bogies 7, 8 are shown schematically below the first module 2 and the first module 4. The parts with the reference symbols 7 and 8 may alternatively be chassis. The first modules 2, 4 have a width B1 that is greater than the width B2 of the second module 3. In the special case, the width B1 is 2,400 mm and the width B2 2,300 mm. As mentioned, the first modules 2, 4 bogie / suspension modules, wherein the first module 2 is also an end module with a driver's cab at the same time. The end module 2 has a rectangular portion 16 and a tapered portion 15, in which the driver's station is housed. The modules 3, 4 each have a rectangular floor plan. The rail vehicle 1 is shown in FIG. 2 when cornering and is based on rails 14. The dashed line 17 shows the envelope 17th In FIG. 3, the view from above falls on the bogie shown in FIGS. 1 and 2.

Chassis module 4. Shown is a cross section through the interior. Shown is a socket 18 as part of a joint for connection to an adjacent one

Salon module, for example, the module 3 of FIG. 2. In the interior of the chassis module 4, which is a first, wider module according to the present invention, a plurality of chairs or seats is provided. Provided with reference numerals is exemplified a pair of seats 19 and another pair of seats 19 '. In this example, a so-called 2 + 2 seating is provided per row. Right and left of the longitudinal axis L of the module 4 are each two juxtaposed seats, or respectively a pair of seats, which are separated by a central aisle. By way of example, the seat pair 19 and the pair of seats 19 'are for a row of seats. Shown are three rows of seats, each with a 2 + 2 seating. Not shown in FIG. 3 is a narrower salon module 3 (see FIG. 2), in which a 2 + 1 seating is provided.

FIG. 4 shows a plan view of the transition region between the first module 4 and the second module 3. Between the modules 3, 4 is the hinge 20 with the mutually rotatable parts 18 and 21, which are each connected to one of the modules 3 or 4. Above the joint 20, not shown here, a turntable is arranged. Furthermore, between the first car body module 4 and the second car body module 3 is a schematically illustrated bellows 1 1, the alternative a

Can be bellows, arranged to close the transition out to the outside. In the illustrated sectional view, two side walls 22, 23 of the bellows 1 1 can be seen. The side walls 22, 23 have on the side of the first car body module 4, ie towards the module 4 out, a greater distance from each other than on the side of the second car body module 3. Thus, in this view, the bellows takes a funnel-shaped course, i. the bellows narrows from the wider first module 4 to the narrower second module 3. Alternatively, in a non-illustrated embodiment, a parallel arrangement of the side walls 22, 23 possible.

In addition, it can be seen that in order to optimize the topic of envelopes in different rail infrastructure networks as a function of the respective smallest differences

Curve radii, the length of the side walls 22 and 23 may be different. It is defined as the distance 24 of two modules to each other, which can occupy a range between 0.7 m and 1, 5 m in.
