Definitions

  • the invention relates to the protection of functional components of a railway car, such as a diesel engine, a compressor, an electric transformer, a braking system, an exhaust gas cleaning system, a tank or wirings, which are located outside the car body of the railway car, on the roof or under the floor of the car body. It relates more particularly to a housing for such components.
  • the roof and/or underframe of a railway car can be equipped with a number of functional components of the railway car, which are usually protected by a housing made of sheet metal.
  • the housing is generally provided with side flaps giving easy access to the components for maintenance purposes.
  • Such a housing which is rendered necessary to streamline the vehicle, protect the component from dust or pollution, prevent access to unauthorised staff and/or reduce the noise generated by the component, adds weight to the vehicle.
  • the weight reduction thus achieved is limited.
  • the housing can be made of sheet metal covered with noise-damping material. Alternatively, it can be made of a plastic material with noise-damping characteristics. However, the mechanical strength of this only elusively mentioned alternative is not discussed.
  • the underfloor includes truck enclosures detachably mounted at positions where trucks are mounted to enclose the periphery of the trucks, and an enclosure for underfloor equipment for enclosing the sides and lower surface of the underfloor equipment.
  • the wiring ducts and underfloor equipment are mounted to the underframe and wiring work is conducted between the wiring duct and the underfloor equipment before the enclosure is mounted, which improves the workability during the assembly process.
  • the enclosure for the underfloor equipment is composed of inside and outside supports, upper and lower frames and side panels pivotably mounted on the upper frame by means of hinges.
  • the lower frames are connected by a joint member horizontally arranged in a lateral direction of the vehicle body and take the form of a ladder, on which small equipment such as switches are installed.
  • the underframe is provided with side beams.
  • the enclosure for underfloor equipment is mounted on fitting rails formed on the side beams by means of detachable fastening members such as bolts.
  • the enclosure includes a great number of constituent parts, which involves a tedious assembly process.
  • the resulting assembly made of a steel frame and sheet metal panels, is heavy.
  • a railway car comprising a car body, at least one component fixed to the exterior of the car body, in particular to a roof or under the floor of the car body, and a housing also fixed to the exterior of the car body and enclosing the component.
  • the housing comprises at least one transverse panel facing the car body and at least one side flap panel movable between a closed position in which the side flap panel closes a volume for the component defined between the transverse panel and the car body and an open position giving access to the volume and to the component.
  • the housing is provided with securing means for securing the side flap panel in the closed position.
  • the side flap panel and the transverse panel are made of lightweight material.
  • the securing means are provided between the transverse panel and the side flap panel in the closed position such that the transverse panel, the side flap panel in the closed position and the securing means form a unitary and interacting self-supporting and load-bearing structure, which is able to sustain the stress experienced during normal operation of the railway car, due in particular to the combined effects of weight, accelerations, deflections, vibrations, temperature variations and wind pressure and defined exceptional loads, e.g. in an overrunning collision.
  • the securing means prevent any relative movement between the transverse panel and the side flap panel in the closed and secured position, whereby forces are integrally transferred between the side flap panel and the transverse panel.
  • the invention relies on the observation that the mechanical requirements on the housing are different when the vehicle is stationary or when the vehicle moves, and on the recognition that the housing does not need to be fully self-supporting when the side flap panel is open (and the vehicle is stationary). Hence, it becomes possible to design a housing in which the side flap panel in the closed position substantially contributes to the shear stiffness and structural strength of the whole housing. In turn, this makes it possible to significantly reduce the mass of the transverse panel and the number of parts of the housing. According to a preferred embodiment, the housing in the open position of the side flap panel does not need to be a self-supporting structure.
  • the transverse panel does not support any part of the enclosed component.
  • the transverse panel does not contact the enclosed component.
  • the side flap panel in the closed position overlaps and is pressed against an outwardly-oriented face of the transverse panel to achieve this unitary structure.
  • the securing means preferably comprise a form-fit and/or friction-fit connection between the transverse panel and the side flap panel.
  • the securing means include at least one self-centering tapered or conical locator, which is able to transfer shearing stress and forces at the interface between the transverse panel and the side flap panel, i.e. forces directed substantially parallel to a contact plane between the side flap panel and the transverse panel, and perpendicular to a main axis of the locator.
  • the securing means may include at least one bolt and nut connection, or a quarter turn fastener.
  • the housing further comprises at least one, and preferably two opposed sheet metal end panels, which extend substantially in a vertical plane.
  • the transverse panel or one of the transverse panels is fixed to at least one such end panel, which in such a case can contribute to stiffening the whole structure of the housing.
  • the housing comprises at least two transverse panels and a metallic structural cross-member having two ends secured to the car body and forming an arch extending between the two transverse panels, each of the two transverse panels being secured to the structural cross-member.
  • This optional arched cross-member is used to stiffen the structure if the length of the housing is not compatible with a single transverse panel.
  • the lightweight material preferably comprises an anisotropic composite material, in particular with a fibre-reinforced thermoset or thermoplastic matrix.
  • the fibre-reinforced composite material may include a low-density core material sandwiched between fibre-reinforced layers.
  • the core material may be a honeycomb structure, a foam and/or a folded honeycomb structure.
  • a waterproof core is used.
  • the housing further comprises at least one metallic hinge for hinging the side flap panel to the car body.
  • the hinge connection ensures easy opening and closing of the housing.
  • the hinge is preferably such as to limit or prevent axial movement between the side flap panel and the car body. Hence, the hinge connection between the side flap panel and the car body contributes to the structural strength of the whole housing.
  • the housing may include at least one side flap panel on each side of the railway car.
  • the housing is fixed to an underframe of the car body and the transverse panel is a bottom panel. According to another embodiment, the housing is fixed to a roof of the car body and the transverse panel is a cover panel.
  • a railway car 10 e.g. a passenger or freight car hauled by a locomotive or a self-propelled rail car, comprises a car body 12 supported by bogies 14.
  • the railway car is provided with an external subunit 16 such as a HVAC unit located on the roof 18 of the car body 12 and enclosed in a housing 20.
  • the railway car 10 is also provided with a an external subunit 22 such as a diesel engine or a braking unit, supported under the floor 24 of the car body by an underframe of the car body and enclosed in a housing 26.
  • Both housings 20, 26 are made of composite panels, as will be described in detail below, with reference to Fig. 2 to 6 and to the underframe housing 26.
  • the housing 26 is made of four bottom panels 28, 30, 32, 34, two side flap panels 36, 38 resp. 40, 42 on each side of the car body 12, two end walls 44, 46 and a structural cross-member 47.
  • the structural cross-member 47 has two ends 47.1 secured to the car body 12 and forms an arch extending between the two transverse panels 30, 32, which are secured to the structural cross-member 47 by clamping means.
  • the bottom and side flap panels which have no contact with the subunit 16, 22, are made of fibre-reinforced composite materials e.g. polyurethane sandwich structures whereas the end walls and cross-member are metallic, e.g. made of aluminium.
  • the bottom panels 28, 30, 32, 34 extend horizontally from one side flap panel 36, 38 to the opposed side flap panel 40, 42 on the other side of the car body. They are connected to one another by means of any appropriate unremovable or removable securing means, such as glue and screws. They are provided with slanted lateral end portions 28.1, 30.1, 32.1, 34.1 to form a substantial planar contact interface with the side flap panels.
  • the side flap panels 36, 38, 40, 42 are articulated to the underframe of the car body of the vehicle by means of hinges 48.
  • Each hinge 48 as illustrated in Fig.4 , has a stationary wing 48.1 attached to the car body structure, in this instance to the underframe of the car body, and a movable wing 48.2 which pivots about a pivot axis 48.3 and is attached to the side flap panel 36 to allow movement of the side flap panel 36 with respect to the car body 12 and to the bottom panels between a closed position and an open position.
  • the side flap panel 36 is equipped with an attachment plate 37 provided with studs 37.1 on which the movable wing 48.2 is attached by means of bolts (not shown).
  • the hinge connection 48 is such as to limit axial motion of the side flap panel 36 with respect to the car body parallel to the pivot axis 48.3 and to integrally transmit forces parallel to the pivot axis 48.3 from the side flap panel 36 to the car body 12.
  • a sealing is provided around the side flap panels.
  • the side flap panels are also provided with handles.
  • an inwardly-oriented flat face 36.1, 38.1, 40.1, 42.1 of each side flap panel 36, 38, 40, 42 contacts and overlaps an outwardly oriented face 28.11, 30.11, 32.11, 34.11 of the slanted lateral end portion 28.1, 30.1, 32.1, 34.1 of at least one of the bottom panels and bears against it.
  • the side flap panel can be secured to the bottom panel by means of securing means including bolt and nut connections 50 depicted in Fig. 5 and tapered locators 52 depicted in Fig. 6 .
  • the bolt and nut connection 50 illustrated in Fig. 5 comprises a nut 50.1 made of two parts 50.11, 50.12 that bear on the two opposed faces 28.11, 28.12 of the slanted lateral end portion 28.1 of the bottom panel 28, a receiving sleeve 50.2 also made of two parts 52.31, 52.32 inserted in the side flap panel 36 and a bolt 50.3 inserted in the sleeve 50.2 and in threaded engagement with the nut 50.1.
  • the tapered locator 52 illustrated in Fig. 6 consists of a tapered pin 52.1 protruding from the slanted lateral end portion 28.1 of the bottom panel 28 and is received in a mating conical and reinforced hole 52.2 provided in the side flap panel.
  • the tapered locator 52 and bolt 50 have insertion axes 52.5, respectively 50.5 that are perpendicular to the contact faces 28.11, 36.1 of the bottom panel 28 and side flap panel 36, and preferably perpendicular to the direction of motion of the side flap panel 36 at the point of contact with the bottom panel 28.
  • the tapered locators 52 are engaged at the end of the motion of the side flap panel 36, 38, 40, 42 towards the closed position, and the bolts 50 are engaged afterwards.
  • the tapered locators 52 ensure a permanent radial contact between the tapered pins 52.1 the conical holes 52.2, and therefore a clearance-free connection.
  • the tapered locators 52 are designed such that the top of the tapered pin 52.1 is visible, preferably flush with the outer surface of the side flap panel 36 in the closed position to allow inspection of the closing position of the side flap panel 36.
  • the bolt and nut connection 50 apply the required axial force between the two contact surfaces 28.11, 36.1. Obviously, the description made with reference to the bottom panel 28 and side flap panel 36 also applies to the other panels, e.g. roof panels.
  • various modifications can be made.
  • various securing means can be selected.
  • the orientation of the lateral end portion of the bottom panel with respect to the general plane of the bottom panel can vary from 0° to 90° depending on a number of factors including the ergonomics for the staff opening and closing the housing, the volume of the enclosed component and the hull of the vehicle.
  • the Side flap panels can partly encompass the bottom of the bottom panels, in which case the connecting means provide form fit only in the longitudinal direction of the railway car.
  • the outer edges of the bottom panels may be reinforced only in the longitudinal direction of the railway car.
