Abstract
Description
- The present invention relates to a passenger car for railway transportation, and more specifically to the problematic of accessing a passenger car from a platform situated at a level below a floor of a vestibule of the passenger car.
- Passenger cars for railway transportation are provided with one or more side doors, which can be located close to the longitudinal ends of the passenger car or distributed along its length. A door located close to an end of the passenger car offers the advantage of also allowing access to an adjacent car through an intercommunication. It enables to clearly separate the vestibule from the saloon, e.g. with a door or a partition, and to maximise the space allocated to the saloon. In a passenger car with two decks, the vestibule at the end of the passenger is often located at an intermediate level between the two decks car and gives access to a flight of stairs to the upper deck and a flight of stairs to the lower deck.
- The car body of a passenger car is usually supported on one or more bogies, which are usually located close to the ends of the car body, or between cars in the case of articulated rail vehicles. In such cases, the vestibule and the side doors are often located at least partially above one of the bogies.
- Side doors located above the bogies provide an additional advantage whenever the passenger car is on a curved track alongside a curved platform at a railway station: in such an instance, the side wall of the passenger car is at a distance from the platform, which varies with the curvature of the platform, an these variations are kept at a minimum at the level of the bogies.
- In instances where the platform is at a low height, there may be a need to provide one or more external steps at the doorway, between the vestibule and the platform. Whenever the vestibule and the side doors are located above a bogie, it becomes challenging to find room to accommodate external steps, because of the conflicting space requirements with the bogie. One solution consists in a pivotable step, which pivots by 90° about a horizontal pivot axis between a vertical position and a horizontal position. The horizontal pivot axis is usually located below the door sill, as far as possible from the longitudinal centre plane of the car body, so as to avoid interference with the bogie when the bogie rotates relative to the car body about a vertical axis of rotation. The depth of the pivotable step, however, is limited for at least two reasons. First, any interference with the platform should be avoided before the step reaches its operational position, which involves that a safety margin has to be taken into account when defining the distance between the pivot axis and the edge of the platform. Second, the depth of the pivotable step cannot be greater than the distance between the door sill and the pivot axis, which is directly related to the height of the external step relative to the door sill. Standards, however, usually require that the maximum height of the external step (typically 200 mm) should be less than its minimum depth (usually 240 mm). Hence, pivotable steps do not easily meet standard requirements in terms of ergonomics and passenger comfort.
- The invention aims to provide a vehicle configuration in which a side doorway located above a bogie can be provided with an external access step that has a comfortable depth.
- According to a first aspect of the invention, there is provided a passenger car for railway transportation, the passenger car comprising: a car body and at least one bogie for supporting the car body. The car body is provided with a vestibule, at least one side doorway on one left or right side of the car body for boarding and alighting from the vestibule, a side door for closing the side doorway, and an external access step movable in a transverse direction of the passenger car between a retracted position and at least one protruding position. The bogie comprises a front set and a rear set of left and right wheels for rolling on left and right rails of a rail track, respectively, and a front set and a rear set of left and right bearings for guiding the front set and the rear set of left and right wheels, respectively. The doorway is located at least partially between a front vertical transverse plane containing a revolution axis of the front set of left and right wheels and a rear vertical transverse plane containing a rear revolution axis of the rear set of left and right wheels. The front and rear sets of left and right bearings are located between the left and right wheels of the front and rear sets of left and right wheels, respectively. The external access step in the retracted position is located below the vestibule, whereas in the protruding position, the external access step at least partially extends in front of the side doorway.
- Because of the specific location of the bearings, the bogie has a reduced width, which provides room for the external access step in the retracted position. Hence, the depth and the height of the external access step can be defined independently from one another and can more easily meet the requirements of the operator, with given constraints in terms of platform height and passenger comfort.
- In a preferred embodiment, the external access step in the retracted position is lower than an upper end of the wheels of the front and rear sets of the left and right wheels. Hence, access to the vestibule of the car body from a very low platform is still possible with only one external access step.
- The motion of the external access step between the retracted position and the protruding position is preferably a planar motion, i.e. a motion parallel to a plane, preferably a transverse vertical plane.
- In a preferred embodiment the external access step is guided so as to remain parallel to itself between the retracted position and the protruding position. Advantageously, an actuator is provided for moving the external access step from the retracted position to any one of a plurality of operational positions between the retracted position and the extended position and for maintaining the external access step in said operational positions. Hence, the position of the external access step relative to a platform can be adjusted. In an embodiment, [CLAIM 5]. An automatic adjustment takes place on each platform, so that the gap between the external access step and the platform can be minimised.
- The external access step can be guided in translation between the retracted position and the protruding position. Alternatively, the motion of the external access step between the retracted position and the protruding position can be a combination of rotation and translation, e.g. the motion resulting from the deformation of a parallelogram linkage.
- Preferably, the bogie comprises a bogie frame, a primary suspension between the front and rear sets of left and right bearings and the bogie frame and a secondary suspension between the bogie frame and the car body, and the secondary suspension comprises a set of left and right vertical springs. In practice, the car body may comprise an underframe and each of the left and right vertical springs of the secondary suspension has preferably an upper end fixed in a vertical direction relative to the underframe and a lower end fixed in a vertical direction relative to the bogie frame. The vertical springs may comprise one or more of the following: pneumatic springs, helicoidal springs rubber springs.
- In one embodiment, to provide more room for housing the external access step, a barycentre of a footprint of the set of left and right vertical springs on a horizontal plane is located within a rectangle tangential to the footprints of the sets of left and right wheels at least when the passenger car is stationary on a horizontal straight track.
- In one embodiment, the bogie frame comprises a set of left and right longitudinal beams located between the left and right wheels of each of the sets of left and right wheels and at least one transverse beams integral with the set of left and right longitudinal beams, and the primary suspension connects the sets of left and right bearings to the left and right longitudinal beams, respectively. The bogie frame can be made in one piece of steel, cast iron or light metal, or it can be welded or otherwise assembled from several pieces.
- The vestibule comprises a floor. In one embodiment, the car body has a lower deck and an upper deck, in which case the floor of the vestibule is preferably at an intermediate level between the lower deck and the upper deck. Alternatively, the passenger car can have a single deck, in which case the floor is preferably flush with the deck.
- In one embodiment, the vestibule also comprises at least one inner step, the inner step being lower than the floor, the inner step being located at the side doorway, between the floor and the side door in the closed position. Such an inner step is useful when the platform is particularly low. If necessary, the inner step is lower than an upper end of the wheels of the front and rear sets of the left and right wheels.
- In one embodiment, the side door is a double leaf side door. Alternatively, a single leaf side door is also possible.
- In one embodiment, the car body comprises an opposite side doorway, on an opposite left or right side of the car body for boarding and alighting from the vestibule of the car body, an opposite side door for closing the opposite side doorway, the vestibule comprising an opposite inner step, the opposite inner step being lower than the floor of the vestibule, the opposite inner step being located at the opposite side doorway, between the opposite side door and the floor of the vestibule when the opposite side door is in a closed position, transversally outward from the sets of left and right wheels of the bogie.
- In one embodiment, the bogie is located longitudinally between two longitudinal ends of the car body. In an alternative embodiment, the bogie protrudes from a longitudinal end of the car body, so as to constitute a Jacob bogie.

- With reference to
Figure 1 , apassenger car 10 for railway transportation, comprises acar body 12 supported on a pair ofbogies 14. - The
car body 12 consists of anunderframe 16, left andright sides 18 and aroof 20, which extend along alongitudinal axis 100 of thepassenger car 10 between two opposite longitudinal ends 22 of thecar body 12. The car body can be divided into twoend sections 24, each comprising one of theends 22 of thecar body 12, and amedian section 26 located between theend sections 24. Themedian section 26 accounts for more than half the overall length of thecar body 12 and accommodates one or twodecks end sections 24 may be provided with a driver's cabin (not shown) or anend doorway 32 for accessing a neighbouring car body, as illustrated infigures 2 and 3 . In this embodiment, eachend section 24 is provided with twoside doorways 34 on the left andright sides 18 of thecar body 12 for boarding and alighting avestibule 36 of thecar body 12. Theside doorways 34 are closed by doubleleaf side doors 38. It is to be understood that this configuration is not limitative:side doorways 34 may be provided at oneend 24 only or on oneside 18 only of thecar body 12. Additional side doorways may be provided in themedian section 26. - The vestibule 36 comprises a
floor 40 and at least oneinner step 42, which is lower than thefloor 40 and located at theside doorway 34, between theside door 38 and thefloor 36 when theside door 38 is in a closed position, as illustrated infigure 5 . In the case of a doubledeck passenger car 10, the vestibule 36 is preferably located at intermediate height between the lower andupper decks - The
bogies 14, illustrated infigures 4 and7 , are located each below one of theend sections 24 of thecar body 12, and each at least partially below thevestibule 36. Each of thebogies 14 comprises abogie frame 44, a front set and a rear set of left andright wheels 46 for rolling on a rail track, a front set and a rear set of left andright bearings 48 for guiding the front and rear sets ofwheels 46, respectively, aprimary suspension 50 between the sets of left andright bearings 48 and thebogie frame 44 and asecondary suspension 51 between thebogie frame 44 and theunderframe 16 of thecar body 12. Thewheels 46 of each set can be independent or mounted on acommon axle 54. The set offront bearings 48 is located between the left andright wheels 46 of the front set of wheels, while the set ofrear bearings 48 is located between the left andright wheels 46 of the rear set of wheels. - The
bogie frame 44 comprises a set of left and rightlongitudinal beams 56 located transversally between the left andright wheels 46 of each of the front and rear sets of wheels and at least onetransverse beam 58 integral with the set of left and right longitudinal beams 56. Theprimary suspension 50 connects the front and rear sets ofbearings 48 to the left and rightlongitudinal beams 56, respectively. - The
secondary suspension 51 comprises a set of left and rightvertical springs 52, which have an upper end fixed in a vertical direction relative to theunderframe 16 and a lower end fixed in a vertical direction relative to thebogie frame 44. Thevertical springs 52 may comprise one or more of the following: pneumatic springs, helicoidal springs rubber springs. - Viewed from above, when the
passenger car 10 is stationary on a horizontalstraight track 1, abarycentre 60 of a footprint of the set of left and rightvertical springs 52 on a horizontal plane is located within thesmallest rectangle 200 containing the footprints of the sets of left andright wheels 46, i.e. a rectangle tangential to the footprints of the sets of left andright wheels 46, as illustrated infigure 7 . - With this configuration, room is provided for accommodating the
inner step 42 of the vestibule 36 and anexternal access step 62 transversally outward from thebogie 44. - The
external access step 62 is movable in translation between a retracted position (figures 3 ,5 and9 ) below theinner step 42 and a protruding position (figure 2 ,6 ,8 and10 ) in front of the side doorway, below theinner step 42. Theexternal access step 62 is moved by anactuator 64, here depicted as amotor 66 which drives apinion 68 which engages with arack 70 formed on the lower face of theexternal access step 62, while the step is guided by arunner 72. Theexternal access step 62 may be equipped with a proximity orcontact sensor 74 connected to acontroller 76 for controlling theactuator 64, as schematically illustrated infigure 11 . - The extendable
external access step 62 fulfils two functions. When theplatform 78 is low, as illustrated infigure 6 , it serves as an intermediate step between theinner step 42 and theplatform 78. When theplatform 78 is higher than theexternal access step 62, as illustrated infigure 8 , theexternal access step 62 can still be extended so as to provide a gap filler between theinner step 42 and theplatform 78. - To ensure that the
wheels 46 do not collide with theexternal access step 62 when the bogie pivots relative to thecar body 12 about a vertical pivot axis within preset boundaries, the width W of theexternal access step 62 and of thedoorway 34 is preferably shorter than the distance L between the revolution axes 300 of the front and rear set ofwheels 46. Theexternal access step 62 and thedoorway 34 are preferably between the transversevertical planes 400 which contain the revolution axes 300. - In practice the vertical distance between the
floor 40 of the vestibule 36 and theinner step 42 is between 150 mm and 250 mm, as well as the vertical distance between theinner step 42 and theexternal access step 62. - In an alternative embodiment, at least one of the bogies is a Jacob bogie, which protrudes from a longitudinal end of the car body and is located partially below the vestibule.
