Description
[0001] The invention relates to a vehicle, in particular a rail
vehicle, with a vehicle body and a floor.
[0002] In vehicles with different materials for the floor and the
vehicle body shell, there is the problem that the floor and the
vehicle body expand differently in the event of temperature
fluctuations. This may in some cases lead to a collision of the
floor with the vehicle body in the longitudinal direction of the
vehicle and/or in the transverse direction of the vehicle. In this
instance, increases of stress are produced in the components and
may occasionally lead to an immediate or subsequent failure of the
component.
[0003] An object of the invention is accordingly to provide a
vehicle, in particular a rail vehicle, which takes better account
of the problem of potential temperature fluctuations than previous
vehicles.
[0004] This object is achieved according to the invention with a
vehicle having the features according to patent claim 1.
Advantageous embodiments of the vehicle according to the invention
are set out in dependent claims.
[0005] Accordingly, there is provision according to the invention
for the floor in at least one edge portion adjacent the vehicle
body to be separated from the vehicle body by a resiliently
deformable intermediate member, wherein the intermediate member is
retained by means of a vehicle-body-side securing profile which is
arranged on the vehicle body.
[0006] A significant advantage of the vehicle according to the
invention can be seen in that the resiliently deformable
intermediate member enables a relative movement between the vehicle
body and floor in the case of temperature fluctuations as a result
of the resilience thereof, whereby the occurrence of mechanical
stresses in the components is prevented or at least reduced.
[0007] It is considered to be advantageous for the
vehicle-body-side securing profile to have a hollow chamber which
extends in the longitudinal direction of the securing profile. Such
a hollow chamber increases the stability of the securing profile
which retains the intermediate member; furthermore--and this is
particularly advantageous--the hollow chamber can be used to heat
the securing profile. The hollow chamber preferably has a closed
contour in cross-section.
[0008] The vehicle-body-side securing profile is preferably a
separate component which is secured, in particular screwed, to the
vehicle body. Preferably, the securing profile is an extruded
profile-member whose longitudinal direction is oriented in a
parallel (or perpendicular) manner relative to the longitudinal
direction of the vehicle in order--together with the intermediate
member which is secured thereto--to enable a relative movement
between the floor and vehicle body in the transverse direction of
the vehicle (or longitudinal direction of the vehicle).
[0009] Alternatively, the vehicle-body-side securing profile may
also form a component of the vehicle body or vehicle body shell, in
particular an integral component of the vehicle body or vehicle
body shell, for example, when the vehicle body or the vehicle body
shell is produced from extruded profile-members.
[0010] In order to enable a relative movement between the floor and
the vehicle body in the transverse direction of the vehicle at
both--when viewed from the vehicle side--lateral edges of the
floor, it is considered to be advantageous for a first resiliently
deformable intermediate member and a first vehicle-body-side
securing profile which retains the first intermediate member in the
longitudinal direction of the vehicle to be arranged at one vehicle
side and for a second resiliently deformable intermediate member
and a second vehicle-body-side securing profile which retains the
second intermediate member in the longitudinal direction of the
vehicle to be arranged at the opposing vehicle side.
[0011] A relative movement both in the longitudinal direction of
the vehicle and in the transverse direction of the vehicle can
advantageously be made possible when the floor is separated along
the entire outer contour thereof from the vehicle body by
resiliently deformable intermediate members and forms a floating
floor.
[0012] In order to enable the vehicle-body-side securing profile to
be heated in a particularly simple manner, it is considered to be
advantageous for a heating element to be retained or guided in the
hollow chamber.
[0013] The heating element may preferably be an electrical heating
element which is arranged inside the hollow chamber. Electrical
connections of the electrical heating element are preferably guided
outward out of the hollow chamber through one of the two end-face
openings of the hollow chamber or through both end-face openings of
the hollow chamber.
[0014] An alternative but equally advantageous feature is for the
hollow chamber to form or contain a fluid line. In the case of such
an embodiment, it is particularly advantageous for the hollow
chamber to have a closed contour in cross-section and consequently
to be able to take on the fluid guiding itself or alone.
[0015] The end-side openings of the hollow chamber are preferably
used to supply or discharge a fluid.
[0016] With respect to fluid handling, it is considered to be
advantageous for there to be connected to one of the end-face
openings of the hollow chamber a supply device by means of which
there can be supplied to the hollow chamber a fluid which flows
through the hollow chamber after being supplied.
[0017] In order to enable the fluid to be heated in a particularly
simple manner before it is supplied to the hollow chamber, it is
considered to be advantageous for the supply device to have a
heating device.
[0018] It is possible to supply as the fluid, for example, a gas,
for cost reasons preferably air, to the hollow chamber.
Accordingly, it is advantageous for the supply device to comprise a
ventilator or a fan which during operation supplies as the fluid
gas, in particular air, to the hollow chamber.
[0019] Alternatively, a liquid can be used as a fluid for heating
the hollow chamber; in this instance, it is considered to be
advantageous for the supply device to comprise a pump which during
operation supplies a liquid to the hollow chamber.
[0020] In order to prevent a liquid which is supplied to the hollow
chamber from being able to freeze therein, it is considered to be
advantageous for the freezing point of the liquid to be
sufficiently low. Preferably, the freezing point of the liquid is
less than -20.degree. C. It is possible to use, for example, a
glycol- or ethylene glycol-containing liquid as the liquid.
[0021] In order to achieve particularly good thermal insulation
between the two securing profiles and between the floor and the
vehicle body, it is considered to be advantageous for the
intermediate member to comprise a thermally insulating material, in
particular rubber or plastics material.
[0022] A good thermal insulation by the intermediate member can be
achieved if the intermediate member has in cross-section one or
more hollow chambers whose longitudinal direction extends parallel
with the longitudinal direction of the hollow chamber of the
vehicle-body-side securing profile. The intermediate member may,
for example, be an extruded profile-member.
[0023] With regard to adequate safety of access in the region of
the intermediate member or in the region between the floor and the
vehicle body, it is advantageous for the intermediate member to be
covered with a covering profile. The covering profile is at the
vehicle body side preferably secured to the vehicle body and/or the
vehicle-body-side securing profile; at the floor side, the covering
profile is preferably positioned in a displaceable manner on the
floor or the floor-side securing profile which is fitted to the
floor and which retains the intermediate member at the floor
side.
[0024] In a particularly preferred manner, the resiliently
deformable intermediate member separates the floor from the vehicle
body shell, in particular a vehicle body shell wall of the vehicle
body shell. The vehicle-body-side securing profile is accordingly
preferably fitted to the vehicle body shell, in particular a
vehicle body shell wall, or is alternatively formed by a portion of
the vehicle body shell or the vehicle body shell wall.
[0025] The invention further relates to a method for operating a
vehicle having a vehicle body and floor, in particular for
operating a vehicle, as has been described above.
[0026] According to the invention, with regard to such a method,
there is provision for heating a hollow chamber which extends in
the longitudinal direction of a vehicle-body-side securing profile
which carries a resiliently deformable intermediate member which
separates the floor from the vehicle body.
[0027] With regard to the advantages of the method according to the
invention, reference may be made to the above statements in
relation to the vehicle according to the invention since the
advantages of the vehicle according to the invention substantially
correspond to those of the method according to the invention.
[0028] The invention is explained in greater detail below with
reference to embodiments; in the drawings by way of example:
[0029] FIG. 1 shows an embodiment of a vehicle-body-side securing
profile, a resiliently deformable intermediate member which is
secured thereto and a floor-side securing profile which is
connected to the intermediate member,
[0030] FIG. 2 shows the arrangement according to FIG. 1 formed from
the vehicle-body-side securing profile, the intermediate member and
the floor-side securing profile after installation in a vehicle
body of a rail vehicle which is not illustrated in greater
detail,
[0031] FIG. 3 shows the arrangement comprising the
vehicle-body-side securing profile, the intermediate member and the
floor-side securing profile according to FIG. 1 after assembly of
an electrical heating device in a hollow chamber of the
vehicle-body-side securing profile, and
[0032] FIG. 4 shows the arrangement formed from the
vehicle-body-side securing profile, the intermediate member and the
floor-side securing profile according to FIG. 1 after an air supply
device has been connected to a hollow chamber of the
vehicle-body-side securing profile.
[0033] In the figures, for the sake of clarity, the same reference
symbols are always used for identical or comparable components.
[0034] FIG. 1 shows a securing profile 10 which is suitable for
securing to a vehicle body wall (not shown in FIG. 1) of a vehicle
body (or vehicle body shell) and is consequently referred to below
as a vehicle-body-side securing profile.
[0035] The vehicle-body-side securing profile 10 is preferably an
extruded profile-member whose extrusion direction or whose
longitudinal direction is indicated in FIG. 1 with the reference
symbol S.
[0036] The vehicle-body-side securing profile 10 has securing holes
11 which enable the securing profile 10 to be screwed to the
vehicle body wall. FIG. 1 further shows a hollow chamber 12 which
extends in the extrusion direction or the longitudinal direction S
of the securing profile 10 and which has two end-face openings 12a.
The hollow chamber 12 has in the embodiment according to FIG. 1 a
closed contour.
[0037] In addition to the hollow chamber 12, the vehicle-body-side
securing profile 10 is provided with a rail-like retention portion
13 which enables securing of a resiliently deformable intermediate
member 20 to the securing profile 10. The deformable intermediate
member 20 is preferably an extruded profile-member of rubber or
plastics material, that is to say, a material with the lowest
possible thermal conductivity.
[0038] The resiliently deformable intermediate member 20 is also
provided with hollow chambers which are indicated in FIG. 1 with
the reference symbol 21. The longitudinal direction of the hollow
chambers 21 preferably extends parallel with the longitudinal
direction of the hollow chamber 12 and consequently parallel with
the extrusion direction or longitudinal direction S of the securing
profile 10.
[0039] At the side of the resiliently deformable intermediate
member 20 facing away from the vehicle-body-side securing profile
10, there is fitted a securing profile 30 which is suitable for
assembly on a floor of a rail vehicle not shown in FIG. 1 and which
is consequently also referred to below as a floor-side securing
profile 30.
[0040] In order to secure the floor-side securing profile 30, there
are provided securing holes 31 which enable the securing profile 30
to be screwed to the floor.
[0041] In order to secure the floor-side securing profile 30 to the
resiliently deformable intermediate member 20, there is provided a
rail-like retention portion 32 which in terms of its shape may
correspond to the rail-like retention portion 13 of the
vehicle-body-side securing profile 10.
[0042] The floor-side securing profile 30 is also preferably an
extruded profile-member; the longitudinal direction or extrusion
direction of the floor-side securing profile 30 preferably extends
parallel with the longitudinal direction S or extrusion direction
of the vehicle-body-side securing profile 10.
[0043] FIG. 2 shows the arrangement according to FIG. 1 formed from
the vehicle-body-side securing profile 10, the resiliently
deformable intermediate member 20 and the floor-side securing
profile 30 after assembly in a vehicle body (or a vehicle body
shell) 40 of a rail vehicle 50. The vehicle-body-side securing
profile 10 is screwed to the vehicle body wall 41 of the vehicle
body 40 by means of securing screws.
[0044] The floor-side securing profile 30 is securely screwed to a
floor 60 of the rail vehicle by means of securing screws.
[0045] The resiliently deformable intermediate member 20 which is
located between the two securing profiles 10 and 30 and which is
retained thereby consequently separates the floor 60 at the edge
side from the vehicle body wall 41 so that the floor 60 can move
relative to the vehicle body wall 41, for example, in the event of
temperature fluctuations and the different thermal expansion or
thermal contraction of the materials which occurs with different
thermal coefficients.
[0046] In order to ensure safety of access in the transition region
between the floor 60 and the vehicle body wall 41, the region of
the resiliently deformable intermediate member 20 in the embodiment
according to FIG. 2 is covered with a covering profile 70. The
covering profile 70 is fixed at the vehicle-body-side and, for
example, screwed to the vehicle body wall 41 of the vehicle 40. At
the floor side, the covering profile 70 is not fixed, but is
instead positioned in a displaceable manner on the floor 60. If, in
the event of temperature fluctuations, there is a relative movement
of the floor 60 relative to the vehicle body wall 41 and
consequently an expansion or compression of the resiliently
deformable intermediate member 20, the covering profile 70 will be
able to move on the floor 60 so that the covering profile 70 does
not counteract or prevent the relative movement of the floor 60
relative to the vehicle body wall 41.
[0047] In order to ensure good thermal insulation between the inner
space of the vehicle 50 and the portion below the resiliently
deformable intermediate member 20, the intermediate member 20, as
already mentioned, is preferably provided with the hollow chambers
21 since these considerably increase the thermal insulation of the
intermediate member 20.
[0048] The hollow chamber 12 of the vehicle-body-side securing
profile 10 can be used to heat the securing profile 10 and the
covering profile 70 in order to prevent a slippery formation on the
covering profile 70 in winter and to reduce the risk of accidents.
Embodiments of how the hollow chamber 12 can be heated are
explained in greater detail below in relation to FIGS. 3 and 4.
[0049] FIG. 3 shows the arrangement comprising the
vehicle-body-side securing profile 10, the resiliently deformable
intermediate member 20 and the floor-side securing profile 30
according to FIG. 1 after an electrical heating device has been
pushed into the hollow chamber 12 of the securing profile 10 in the
longitudinal direction S. The electrical heating device 100
preferably extends over the entire length--when viewed in the
longitudinal direction S--of the hollow chamber 12 or over the
entire length of the securing profile 10 in the longitudinal
direction S.
[0050] With a view to simple electrical contacting of the
electrical heating device 100, it is considered to be advantageous
for electrical connections 110 of the heating device 100 to be
guided out of the securing profile 10 at an end-face opening 12a of
the hollow chamber 12.
[0051] In the embodiment according to FIG. 3, the hollow chamber 12
of the securing profile 10 serves to retain or carry the electrical
heating device 100. In order to ensure this function, it is not
absolutely necessary for the hollow chamber 12 to have a closed
contour; the contour of the hollow chamber 12 has to be suitable
only for retaining the heating device 100. Slots or the like in the
contour of the hollow chamber 12 are non-critical as long as the
retention function of the hollow chamber 12 remains ensured.
[0052] In the embodiment according to FIG. 3, the hollow chamber 12
or the vehicle-body-side securing profile 10 is thus heated in an
electrical manner in order to heat the covering profile which is
illustrated in FIG. 2 and which is located above the intermediate
member 20 and to protect it from frost.
[0053] FIG. 4 shows an embodiment in which the arrangement
according to FIG. 1 formed from the vehicle-body-side securing
profile 10, the resiliently deformable intermediate member 20 and
the floor-side securing profile 30 has been provided with a supply
device 200 for supplying warm air L. The supply device 200
comprises a hose 210 which is connected to the end-face opening 12a
of the hollow chamber 12 and which connects the hollow chamber 12
to an air channel 220 of the supply device 200. The air channel 220
may be fitted as a separate component to the vehicle body wall 41
according to FIG. 1 or may form an integral component of the
vehicle body wall 41. For example, the air channel 220 may be
formed by an extruded profile portion of a vehicle-body-side
extruded profile-member of the vehicle body 40.
[0054] The air channel 220 is connected to a fan 230 and a heating
device 240 which are illustrated only schematically in FIG. 4.
[0055] If, in the case of low temperatures, for example, during
winter, a slippery formation in the region of the covering profile
70 according to FIG. 2 is intended to be prevented, the hollow
chamber 12 and consequently the vehicle-body-side securing profile
10 can be heated by hot air being supplied to the hollow chamber 12
by the fan 230 and the heating device 240 through the
vehicle-body-side air channel 220 and the hose 210. In the
embodiment according to FIG. 4, the vehicle-body-side securing
profile 10 and the covering profile 70 according to FIG. 2 are
therefore heated by a fluid in the form of gas which is directed
through the hollow chamber 12. The hollow chamber 12 consequently
performs the function of a fluid line.
[0056] In the embodiment according to FIG. 4, the hollow chamber 12
itself acts as a fluid line; alternatively, it is possible inside
the hollow chamber 12 to provide a fluid hose which takes over
directly the fluid line. In such a case, it is not necessary for
the profile of the hollow chamber 12 or the contour of the hollow
chamber 12 to be completely closed; instead, it is sufficient for
the profile or the outer contour of the hollow chamber 12 to be
suitable for retaining the fluid line. Slots, gaps or other
openings in the hollow chamber profile 12 are consequently
non-critical when a separate fluid line is provided.
[0057] Although the invention has been illustrated and described in
greater detail by preferred embodiments, the invention is not
limited by the disclosed examples and other variations can be
derived therefrom by the person skilled in the art without
departing from the protective scope of the invention.
