Definitions
- 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.
- 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.
- a pivotable step which pivots by 90° about a horizontal pivot axis between a vertical position and a horizontal position, as disclosed e.g. in DE9421209U1 .
- 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 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.
- the invention is defined by the features of claim 1.
- a passenger car for railway transportation 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 and a side door for closing the side doorway.
- the vestibule comprises a floor.
- 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.
- the car body is further provided with 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 inner step and the external access step in the retracted position are located transversally outward from the bogie.
- the external access step in the retracted position is located below the inner step of the vestibule, whereas in the protruding position, the external access step is lower than the inner step and at least partially extends in front of the side doorway.
- the external access step is guided in translation between the retracted position and the protruding position
- the bogie 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.
- 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 parallel to a transverse vertical plane.
- the extendable external access step fulfils two functions. When the platform is low, it serves as an intermediate step between the inner step and the platform. When the platform is higher than the external access step, the external access step can still be extended so as to provide a gap filler between the inner step and the platform.
- the external access step is guided so as to remain parallel to itself between the retracted position and the protruding position.
- 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 protruding position and for maintaining the external access step in said operational positions.
- the passenger car is further provided with a sensor for detecting a position of a platform or a contact between the external access step and the platform or a proximity of the external access step to the platform, and a controller for controlling the actuator based on a signal of the sensor An automatic adjustment takes place on each platform, so that the gap between the external access step and the platform can be minimised.
- 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.
- 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.
- 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.
- 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 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.
- the passenger car can have a single deck, in which case the floor is preferably flush with the deck.
- the inner step is lower than an upper end of the wheels of the front and rear sets of the left and right wheels.
- the side door is a double leaf side door.
- a single leaf side door is also possible.
- 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.
- 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.
- a passenger car 10 for railway transportation comprises a car body 12 supported on a pair of bogies 14.
- the car body 12 consists of an underframe 16, left and right sides 18 and a roof 20, which extend along a longitudinal axis 100 of the passenger car 10 between two opposite longitudinal ends 22 of the car body 12.
- the car body can be divided into two end sections 24, each comprising one of the ends 22 of the car body 12, and a median section 26 located between the end sections 24.
- the median section 26 accounts for more than half the overall length of the car body 12 and accommodates one or two decks 28, 30 equipped with passenger seats (not shown).
- One or both end sections 24 may be provided with a driver's cabin (not shown) or an end doorway 32 for accessing a neighbouring car body, as illustrated in figures 2 and 3 .
