Description
FIELD OF INVENTION
[0001] The invention relates to a coach body for a multiple-unit
railway vehicle having two bogies at each end and to a train set
composed of such coach bodies.
BACKGROUND OF INVENTION
[0002] In the development of multiple-unit railway vehicles, in
particular also train sets, maximizing an available area for seats
as well as for passenger comfort is to the fore. For the example of
a so-called "TSI train" with a length of approximately 200 m, up to
now either coach bodies with a length of approximately 25 m have
been used, which means that said train could be composed of eight
such coach bodies, or the train has been realized as an eleven-unit
articulated train with coach bodies with an approximate length of
17.5 m.
[0003] It is generally assumed in the development of coach bodies
that an increase in the length of the coach body beyond
approximately 25 m involves a marked increase in difficulties in
maintaining stipulated clearance profiles in conjunction with
appropriate inside widths. This is why realizing coach bodies with
lengths in excess of approximately 27.1 m has, up to now, been
disregarded.
SUMMARY OF INVENTION
[0004] It is an object of the invention to provide a coach body
where a larger useful area is made available, in particular in the
case of TSI high speed trains, along with a train composed of such
coach bodies.
[0005] With regard to the coach body, this object is achieved by a
coach body for a multiple-unit railway vehicle having two bogies at
each end, the coach body having a length of at least 27.5 m and
side walls of the coach body being developed such that, with a
maximum outside width in the center of the coach of 2.86 m at the
height of the seat arms, an inside width of at least 2.6 m is
achieved for the greatest part of the coach length (in excess of
50%, preferably in excess of 80%).
[0006] By the coach body having a length of at least 27.5 m, it is
possible to assemble, in particular, a TSI high speed train from
seven coach bodies, such that overall a train with a length of
approximately 200 m is created. This means that, compared to the
prior art, one coach body and consequently one coach-to-coach
connection is omitted, such that available area advantages within
the order of magnitude of approximately 5% can be produced.
[0007] One particular challenge is nevertheless to achieve
appropriate inside widths whilst taking into account the profile
stipulated in accordance with UIC leaflet 505-1. The extending of
the coach body results, with corresponding enlargement of the bogie
distance between centers, in a reduction in the maximum outside
width in the longitudinal center of the coach to less than 2.86 m,
preferably 2.852 m. To achieve good interior comfort, in particular
with 2+2 seating, a minimum inside width at the height of the arm
rests of between 2.600 and 2650 mm must be obtained. In order to
realize this, it is advantageous to use a side wall construction
that is optimized at least at the height of the seat arm rest with
reference to the thickness and the contour and is less than 150 mm,
preferably less than 100 mm, and nevertheless complies with all
characteristics for coach body strength, heat insulation, air
conditioning, etc.
[0008] One feature of such a side wall construction can be in a
bowed realization of the outside contour. This has the advantage
that a stipulated clearance profile can be utilized in an optimum
manner. In particular, a degree of comfort necessary for the
passengers can also be achieved at the height of the arm rests of
passenger seats. However, even with planar side walls, it is
possible to provide the concept with a slightly reduced inside
width.
[0009] A further feature can be an optimized inside contour. The
inside surface of the side wall, in this case, is drawn in
(hollowed out) at the height of the arm rests and just above and
consequently additional space for the arms of the passengers is
created at the relevant height region.
[0010] With regard to the optimum utilization of the profile
stipulated by guideline UIC505-1, indentations are usefully
realized in the region of the end of the coach, that is to say the
side walls to the end walls are drawn towards the coach interior.
These are realized such that where doors are present they only
begin at the door pillar.
[0011] The abovementioned object with regard to the multiple-unit
railway vehicle is achieved in that each coach of the railway
vehicle is realized in accordance with a coach body of the
aforedescribed type. To assemble a TSI 200 m train for high speed
purposes, it is advantageous for the railway vehicle to comprise
seven coach bodies.
BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Exemplary embodiments of the invention are explained below
with reference to the drawings, in which, in detail:
[0013] FIG. 1 shows a cross-sectional view of a coach body for a
railway vehicle and
[0014] FIG. 2 shows a schematically graphic representation of an
admissible half coach body width as a function of a location along
a longitudinal axis of a coach body.
DETAILED DESCRIPTION OF INVENTION
[0015] As can be seen in FIG. 1, a coach body W includes side walls
SR and SL that in this case are bowed for a railway vehicle. In
this case, a maximum coach body width is approximately at the
height of mill rests A that belong to passenger seats F.
[0016] The bowed design of the side walls SR, SL ensures that a
profile stipulated in accordance with guideline UIC505-1 can be
utilized in an optimum manner. A planar side wall contour that
could be proposed as an alternative would be linked to a further
reduced wall thickness.
[0017] The graphic representation in FIG. 2 shows (top line) an
admissible half width of the coach body W in FIG. 1 as a function
of a location along a longitudinal axis of a coach. In this case, a
zero point is established through the center of one of the bogies.
In FIG. 2, the outline of the coach body W is represented by the
punctuated line and the position of the center of the bogies by the
dot-dash line. As a reference, a coach body with a width of 2.85 m
is shown in FIG. 2 in the form of a rectangle. This width is
maintained over almost the entire length of the coach body. At the
coach ends, the side wall SR extends inward in the direction of
associated end sides in order to ensure maintaining the profile
boundary line. In other words: In the region of overhangs, i.e.
those parts of the coach body that protrude beyond the running
gear, the side wall SR extends inward at an angle.
[0018] FIG. 2 also shows the position of door regions TV, TH. These
are in the region of the overhangs, i.e. the side walls SR, SL
extend at an angle here. Entrance doors of the coach body W are
located in the door regions TH, TV.
[0019] The individual coach bodies W are provided with couplings
and coach-to-coach connections that have been lengthened compared
to those of a shorter standard coach in order to cope with the
greater transverse movements caused on account of the larger coach
body overhangs.
[0020] As the coach body W is narrower compared to known coach
bodies, it seems sensible to overcome a gap between the coach body
W and a platform by means of a retractable step (or a folding
step). Said retractable step should have an extendable width of
approximately 0.25 m and is able to avoid a collision with the
platform by means of sensor technology. For the dimension of the
retractable step, the appropriate specification can be found in
"TSI PRM" and standard "UIC505".
[0021] The coach body W explained by way of FIGS. 1 and 2 includes
the following characteristic data: coach length: 27.95 m; bogie
distance between centers: 19.5 m.
[0022] A TSI high speed train can be formed from the coach body W
realized in this manner, seven such coach bodies W being assembled
to form one train. Characteristics of such a train are:
coach-to-coach connection length: 0.8 m; number of coach-to-coach
connections: 6; aerodynamic elongation of head carriage: 0.775 m;
number of elongations: 2. This produces an overall length of 202
m.
[0023] The thickness of the side walls SR, SL at the height of the
arm rests (A) is less than 100 mm. The thickness of the side walls
SR, SL in the region lying above and below this can be greater.
Depending on measures taken elsewhere, it can also be sufficient
for the side wall thickness at the height of the arm rests A to be
less than 150 mm.
[0024] In the exemplary embodiment represented, the maximum outside
width of the coach body in the longitudinal center of the coach is
2.852 m. All in all, it is advantageous for maintaining the
abovementioned standard if the coach body width does not exceed the
value of 2.86 m.
[0025] The coach body (W) designed in this manner ensures an inside
width of at least 2600 mm, it also being possible for the value of
2650 mm to be exceeded.
