TECHNICAL FIELD OF THE INVENTION
[0001] The present invention relates to a floor of a public transportation vehicle. It relates
more precisely to a vehicle body of a public transportation vehicle provided with
a floor covering an underframe.
BACKGROUND ART
[0002] A floating-constructed in-built floor structure of a subway vehicle disclosed in
CN104627190 comprises a floating aluminium honeycomb floor that rests on rubber blocks fixed
to an underframe of the vehicle body. A lateral edge profile of the aluminium honeycomb
floor is fixed to the underframe through a rubber block with a bolt. The rubber block
is fixed in a groove of the underframe and the head of the bolt is embedded in the
rubber block. A bolt rod of the bolt is fixed to the aluminium honeycomb floor. Thus,
metal connection between the aluminium honeycomb floor and the vehicle body is completely
avoided.
[0003] Because of the connection between the bolt rod and the aluminium honeycomb floor,
the assembly of this floor to the underframe requires low tolerances and is relatively
complex and time-consuming.
[0004] A vehicle body with a floating floor is illustrated in
WO15037100. The floating floor includes a set of floor panels that cover an underframe of the
vehicle body. The adjacent edges of two adjacent floor panels are fixed to a common
T-shaped rail, which rests on an elastic member fixed to the underframe. The underframe
is provided with a hook-shaped protrusion, which co-operates with a corresponding
hook fixed to the T-shaped rail to limit the vertical and horizontal relative motion
between the T-shaped rail and the underframe. The assembly process necessitates a
precise positioning of the four different structural elements, which may prove difficult
or time-consuming.
[0005] A railway box car with a floor assembly having a primary floor and secondary floor
is known from
US 2003/196567 A1. A covering plate for flooring in a railway car is known from
WO98/09860 A1.
SUMMARY OF THE INVENTION
[0006] The invention aims to provide a structure that simplifies the assembly of the floor
to the underframe of a public transportation vehicle.
[0007] According to the invention, there is provided a vehicle body of a public transportation
vehicle having the features of claim 1.
[0008] Because the floor panels are no longer fixed to the underframe in the vertical direction,
a significant assembly time is saved. Once the first floor panel has been put in place
on the underframe, the assembly of the second floor panel is particularly simple.
[0009] The floor panels can have an aluminium honeycomb structure covered on the upper face
with linoleum and, if necessary, with a heat and/or noise insulation material on the
lower face.
[0010] According to one embodiment, the vehicle body further comprises opposite side walls
and/or opposite access doors on opposite sides of the underframe, wherein the floor
panels extend from one of the opposite side walls or opposite access doors to the
other. Preferably, each of the floor panels extends transversally from one of the
opposite side walls to the other.
[0011] Means are provided for retaining the floor panels in a longitudinal direction of
the vehicle with respect to the underframe. More specifically, the underframe is provided
with one or more retention channels extending in a transverse direction of the vehicle
body and each provided with opposite retention walls that are parallel to a vertical
transverse plane of the vehicle body and wherein at least one, and preferably only
one, of the floor panels is provided with one or more retention protrusions received
in the one or more retention channels between the opposite retention walls at a distance
of each of the opposite retention walls, the retention channel and retention protrusion
being preferably made of light metal. The space between the protrusion and each of
the retention walls ensures a limited freedom of movement of the floor panel in the
direction perpendicular to the retention walls, i.e. in the longitudinal direction
of the vehicle body. The protrusion can be a continuous rib that protrudes downwardly
from the floor panel. The retention channel is preferably a U-shaped profile. The
distance between the two retention walls is preferably between 20 and 40 mm. Preferably,
the one or more retention channels are each provided with resilient elements between
each of the retention walls and the one or more retention protrusions. The protrusion
is preferably at a distance of each or the resilient elements, at least in a nominal
position of the vehicle body.
[0012] Advantageously, the overlapping edge profile and overlapped edge profile are provided
with one or more interlocking cavities and protuberances.
[0013] The upper faces of the first and second floor panels are flush with one another,
and the interlocking edge profiles are located below the common floor plane.
[0014] The one or more retention protrusions protrude downwardly from the overlapped edge
profile.
[0015] Advantageously, the second floor panel has no direct contact with the underframe.
Accordingly, the position of the second floor panel in the longitudinal direction
is set by the inteelocking with the first floor panel.
[0016] Preferably, the vehicle body is further provided with fixing means for fixing the
overlapping edge profile to the overlapped edge profile. Once assembled, the first
and second floor panels form a unit.
[0017] According to a preferred embodiment, the first panel is an intermediate panel, located
at a distance of the two ends of the vehicle body. Preferably, the set of floor panels
comprises a third floor panel adjacent to the first floor panel, the first floor panel
being located longitudinally between the second and third floor panels, the first
floor panel being provided with a further overlapped edge profile, the third floor
panel being provided with a further overlapping edge profile that overlaps the further
overlapped edge profile, wherein the further overlapping edge profile rests on the
further overlapped edge profile. The first floor panel is the first to be installed
on the underframe. The second and third panels are installed in subsequent steps of
the assembly process. Only the first floor panel has to be precisely positioned with
respect to the underframe. The second and third floor panels, on the other hand, are
positioned relative to the first floor panel. Preferably, the first floor panel is
substantially shorter than the second and third floor panels. In one embodiment, the
length of the first floor panel measured in the longitudinal direction of the vehicle
body is between 1/5 and 1/3 of the length of the second and third floor panels, which
are preferably substantially equal.
[0018] The two overlapping edge profiles have preferably the same shape, and the two overlapped
edge profiles too. Fixing means can be provided for fixing the further overlapping
edge profile to the further overlapped edge profile.
[0019] According to one embodiment, the unit formed by the first, second and third floor
panels is retained in the longitudinal direction solely by the retaining channel and
the one or more retaining protrusions.
[0020] Alternatively, the underframe is provided with at least a further retention channel
extending in a transverse direction of the vehicle body and provided with opposite
retention walls that are parallel to a vertical transverse plane of the vehicle body
and the further overlapped edge profile is provided with one or more further protrusions
received in the further retention channel between the opposite retention walls of
the further retention channel. Preferably, the third floor panel has no contact with
the underframe.
[0021] According to a preferred embodiment, the set of floor panels consists of the first,
second and third floor panels, which cover an entire floor space of a saloon of the
vehicle body. The floor panels are preferably mounted on the underframe before the
side walls are erected.
[0022] According to an embodiment, the first floor panel extends transversally between two
opposite access doors of the vehicle body, preferably centrally located between two
ends of the vehicle body.
[0023] Advantageously, the vehicle body is further provided with resilient blocks, wherein
the floor panels bear against an upper face of the resilient blocks, and a lower face
of the resilient blocks bears against the underframe. Preferably, the resilient blocks
include resilient profiles that extend in a longitudinal direction of the vehicle
body. As the floor panels rest on the resilient pads, a true floating floor is realised.
According to one embodiment, the resilient profiles include side profiles that are
located along longitudinal edge profiles of the floor panels. Additional profiles
parallel to the two side profiles may be located at intermediate locations between
the two side profiles. The profiles preferably extend along the whole length of the
vehicle body, if necessary with small interruptions.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
[0026] A multiple unit vehicle illustrated in figure
1 consists of a front vehicle
10 having a vehicle body
12 provided with a driver's cabin
14 and a passenger saloon
16, one or more optional intermediate vehicles
18 each with a vehicle body
20 with a with passenger saloon
22 extending from one end, and an end vehicle (not shown) which can be with or without
driver's cabin. Each vehicle body
12, 20 has a structure consisting of structural subunits such as an underframe, opposite
side walls
24 and a roof. Each vehicle body has a vertical median plane and a horizontal longitudinal
axis
100.
[0027] The underframe of each vehicle is covered with a floor assembly
26 consisting in a set of three floor panels, namely a first floor panel
28 of short length positioned in the middle of the saloon laterally between two access
doors
29 of the vehicle, and a second floor panel
30 and a third panel
32 positioned each at one end of the first floor panel
28. The second floor panel
30 is located towards the front end of the vehicle and is shorter than the third floor
panel
32 in the front vehicle
10 due to the presence of the driver's cabin
14. In the intermediate vehicles
18 the second and third floor panels
30, 32 are substantially identical with one another. The first floor panel
28 accounts for approximately 1/10
th of the overall length of the saloon of the front vehicle
10 and 1/11
th of the length of the saloon of the intermediate vehicles. The second floor panel
accounts for 4/10
th of the overall length of the saloon
16 of the front vehicle and 5/11
th of the length of the saloon
22 of the intermediate vehicles
18. The third floor panel
30, which is identical for all vehicles, accounts for half of the overall length of the
saloon
16 of the front vehicle
10 and 5/11
th of the length of the saloon
22 of the intermediate vehicles
18. The second and third floor panels
30, 32 are made of four or five modular units, which are fixed together before assembly
onto the vehicle body. The floor panels
28, 30, 32 define a horizontal floor plane of the vehicle body.
[0028] As illustrated in figures
2 to
4, each floor panel
28, 30, 32 comprises an aluminium honeycomb core
34 faced with upper and lower epoxy coated aluminium sheets
36, 38 and framed into aluminium extrusions. The floor panels are covered with a floor covering
material
40 such as linoleum or rubber and bonded to the upper aluminium sheet
36 under control conditions before assembly into the vehicle. If and where necessary,
the lower aluminium sheet
38 can be covered with a heat and/or noise insulation layer (not shown).
[0029] As illustrated in figure
5, the underframe
42 of the vehicle body
24 is provided with parallel longitudinal channels
44, which extend substantially over the whole length of the saloon and are distributed
at regular intervals in the width direction, with at least two channels
44 close to the two side walls
25 and one to three additional intermediate channels (not shown). Each of these longitudinal
channels
24 receives an extruded profile of resilient material
46, e.g. silicone rubber, which runs over the whole length of the channel
44, with or without interruptions or gaps. These extruded profiles form resilient blocks
which support the whole weight of the floor panels
28, 30, 32.
[0030] As shown in figures
2 and
3, the first floor panel
28 and second floor panels
30 have interlocked aluminium edge profiles
48, 50 that extend in the transverse direction of the vehicle body
12, 20. More precisely, the edge profile
48 of the first floor panel that faces the second floor panel
30 is partly overlapped by the corresponding overlapping edge profile
50 of the second panel
30. The overlapping edge profile
50 is provided with a tapered cavity
52 opened downwardly, and the overlapped edge profile
48 with a tapered protruding key
54 that faces upwardly and is received in the tapered cavity
52. The two slanted faces of the tapered protruding key
54 bear against two slanted faces of the tapered cavity
52. There is no contact between the bottom of the cavity
52 and the tapered protruding key
54. At regular intervals, fixings
56 are used to secure the connection between the overlapping edge profile
50 and the overlapped edge profile
48.
[0031] The overlapped edge profile
48 of the first floor panel
28 is provided with a retention rib
58 that protrudes downwards and received in a U-shaped retention channel
60 of the underframe structure. The retention rib
58 and the retention channel
60 extend over substantially the whole width of the first floor panel
28. The retention channel
60 has two opposite retention walls
62, which are at a distance from one another and from the retention rib
58. Resilient extruded pads
64 are interposed between the retention rib
58 and the retention walls
62, preferably without contact with the retention rib
58, at least in a nominal position of the first floor panel
28. The retention rib
58 is without contact with the bottom of the retention channel
60. As can be readily understood, the retention rib
58 and retention channel
60 do not contribute to the vertical support of the first floor panel
28, but ensure a proper positioning of the first floor panel
58 in the longitudinal direction of the vehicle body, within a limited range determined
by the retention walls
62.
[0032] A similar arrangement is provided at the interface between the first floor panel
28 and the third floor panel
32, as illustrated in figure
4. The edge profile
148 of the first floor panel that faces the third floor panel
32 is the mirror image of the opposite edge profile
48. The corresponding edge profile
150 of the third floor panel is the mirror image of the edge profile
50 of the second floor panel. More precisely, the edge profile
148 of the first floor panel that faces the third floor panel
30 is partly overlapped by the corresponding overlapping edge profile
150 of the third panel
30. The overlapping edge profile
150 is provided with a tapered cavity
152 opened downwardly, and the overlapped edge profile
148 with a tapered protruding key
154 that faces upwardly and is received in the tapered cavity
152. The two slanted faces of the tapered protruding key
154 bear against two slanted faces of the tapered cavity
152. There is no contact between the bottom of the cavity
152 and the tapered protruding key
154. At regular intervals, fixings similar to the fixings
56 are used to secure the connection between the overlapping edge profile
150 and the overlapped edge profile
148. Optionally, the overlapped edge profile
148 may be provided with a retention rib
158 and the underframe
42 with a further retention channel
160 with two retention walls
162 covered by resilient pads
164.
[0033] The assembly of the floor starts with the first floor panel
28, which is laid on the resilient blocks
46 and fitted into the retention channel(s)
60. The second and third floor panels
30, 32 can then be laid on the resilient blocks
46 and the tapered cavities
42 interlocked with the tapered protruding keys. The fixings
56 are screwed to fasten the second and third floor panels
30, 32 to the first floor panel
28. Discs of covering
66 are applied to fill the access holes to the fixings
56 and the joints
68 between adjacent pieces of floor covering
40 at the junction of the three floor panels
28, 30, 32 are sealed.
[0034] The floor assembly
26 as a whole rests on the resilient blocks
48. The retention ribs
58, 158 and retention channels
60, 160 ensure an accurate positioning of the floor assembly
26 in the longitudinal direction and retain the floor assembly
26 as a whole whilst preserving acoustic isolation from the underframe structure. Lateral
retention is provided by the interface with the access doors
29 and vertical retention by the close proximity of the body side panels and draught
screens, etc. The floor assembly is designed to allow for thermal expansion and contraction
mostly in the longitudinal direction and also, to a lesser albeit sufficient extent,
in the lateral direction.
[0035] While the above example illustrates a preferred embodiment of the present invention,
various other arrangements can also be considered, provided they fall under the scope
of the appended claims. In particular, the location, number and shape of the resilient
blocks
46 may vary.
