Definitions

  • the present invention relates to a motorized bogie for a low-floor railway vehicle.
  • the document DE-C1-41 39 228 discloses a motorized bogie according to the preamble of claim 1.
  • a motorized bogie is intended in particular to equip a railway vehicle whose body is arranged in two stages of passenger transport. Usually, the two floors extend along a central portion A of the body which is located between two bogies (as shown in FIG. figure 6 ).
  • Access doors to the vehicle allowing passengers easy access to the vehicle from the dock or dock from the vehicle, are also located between the two bogies. Indeed, because of the height of a conventional bogie, it is not possible to arrange an access door to the right of such a bogie, because the height of this door would then be incompatible with the height of the dock . Conventionally, the doors are arranged next to the bogies of the railway vehicle.
  • the invention is intended to overcome this disadvantage, by proposing a motorized bogie to increase the number of passengers that can be transported in a rail vehicle.
  • the primary suspension means are arranged outside the interior space, and the gearbox is arranged in this interior space.
  • Such a gearbox is particularly bulky, especially in height, so that it is the height of the gear that imposes the low limit of the distance between a wheel support plane and a rail vehicle body carried by the bogie.
  • the structure of the primary suspension means, of which the first suspension elements are arranged in the interior space makes it possible to free space outside this interior space.
  • the reducer does not affect the minimum distance between the wheel support plane and the rail vehicle body.
  • this minimum distance is imposed by the top of the axle boxes, which have a height less than that of the gearbox.
  • the minimum distance between the wheel support plane and the rail vehicle body is less than that imposed by the structure of a bogie of the state of the art.
  • the box being lowered it is possible to arrange a door of this box to the right of the bogie, this door can be arranged at dock level. This makes it possible to increase the length of the central part of the box where the two floors are arranged. The length of the two floors being increased, thus increases the passenger capacity of the body.
  • the invention also relates to a rail vehicle comprising a body, characterized in that it comprises a bogie as defined above.
  • a horizontal plane is substantially parallel to a plane in which bogie axles extend and a vertical plane is substantially parallel to a plane in which bogie wheels extend.
  • longitudinal is defined in its usual sense as applying to the direction in which a rail vehicle extends in a horizontal plane
  • transverse is defined in its usual sense as applying to a direction substantially perpendicular to the longitudinal direction in a horizontal plane.
  • a reference numeral is shown in the figures, in which a longitudinal direction is designated by the reference X, a transverse direction is designated by the reference Y, and a vertical direction, perpendicular to the longitudinal X and transverse Y directions, is indicated by the reference Z.
  • front and rear are defined according to their usual meanings relative to the direction of movement of the railway vehicle in the longitudinal direction X.
  • the term “before” corresponds to the left and the term “back” to the right.
  • a rail vehicle can usually travel in two opposite directions, the terms “front” and “rear” being then inversely reversed when the direction of travel is reversed.
  • a railway vehicle bogie 10 for example for a low-floor regional express transport train (TER).
  • TER low-floor regional express transport train
  • the bogie 10 comprises two pairs 12 of wheels 14, respectively arranged at the front and the rear of the truck 10.
  • the wheels 14 of each pair 12 are carried and connected to each other by an axle structure 30 to this pair 12.
  • Each axle structure 30 comprises two axle boxes 32, namely one for each wheel 14, as well as an axle shaft 34 extending in the transverse direction Y between two ends, each of which carries a respective wheel 14 .
  • an interior space I defined in the transverse direction between the wheels 14 and in the longitudinal direction is defined between the axle shafts 34.
  • axle structures 30 carry a frame 15 via hinges 36 and primary suspension means 40, which will be described later.
  • the frame 15 comprises two lateral beams 16, of the rocker type, each extending parallel to the longitudinal direction X, two crosspieces 17, each extending parallel to the transverse direction Y, thus transversely to the side rails 16, and two supports 18 , of the console type, intended to receive the body 60 of the railway vehicle.
  • Each spar 16 is connected at one of its ends to a respective axle box 32 by means of a respective hinge 36.
  • Each articulation 36 comprises, for example, a rod with an axis parallel to the transverse direction Y, carried at the end of the corresponding spar 16, cooperating with a complementary pivot element carried by the axle box 32. This pivot element is worn. below a top of the axle box 32, in the vertical direction Z, so that the spar 16 extends below this vertex of the axle box 32.
  • this apex of the axle box 32 imposes a minimum limit on a height at which a box 60 of the railway vehicle, carried by the bogie 10, can be arranged.
  • the minimum value of a distance D, represented on the figure 5 between a support plane of the wheels 14 and support means 52 to the rail vehicle body 60 is imposed by the height of this axle box top 32.
  • the primary suspension means 40 comprise first suspension elements 42, arranged between the crosspieces 17 and the longitudinal members 16, providing the connection between these crosspieces 17 and these longitudinal members 16.
  • first transverse openings 19 are formed in the longitudinal members 16 to receive the cross members 17.
  • the first transverse openings 19 have a cross section of general shape identical to that of the cross section of the cross members 17, for example a circular section.
  • Each crossmember 17 passes through a respective one of the first transverse openings 19 of each spar so that each crossmember 17 extends laterally beyond the spars 16.
  • the two crosspieces 17 carry together, at each of their ends, the a respective one of the supports 18 intended to receive the body 60 of the railway vehicle.
  • each cross member 17 has a diameter less than a diameter of the openings 19, so that a free annular space is defined between the cross members 17 and the longitudinal members 16.
  • the first suspension elements 42 are advantageously arranged in the free annular spaces between the longitudinal members 16 and the cross members 17.
  • the first suspension elements 42 each have a generally annular shape, and each form an elastic connection between one of the longitudinal members 16 and a respective one of the crosspieces 17.
  • the annular suspension element 42 has an outside diameter defined in an X-Z plane comprising the longitudinal X and vertical Z directions and an inside diameter defined in the X-Z plane.
  • a difference between this outer diameter and this inner diameter is preferably 100 mm, which corresponds substantially to the difference between the diameter of the cross member 17 and the diameter of the corresponding opening 19. Furthermore, the suspension element 42 has a dimension in the transverse direction Y of between 100 and 150 mm. These first suspension elements 42 are made of an elastic material, for example rubber.
  • the first suspension elements 42 are less eccentric than conventional primary suspension means. More particularly, considering a center of the bogie C, represented on the figure 3 , defined as a point longitudinally halfway between the axles 30, and transversely midway between the planes of the wheels 14, the distance between the first suspension elements 42 and the center C is smaller than the distance between the means conventional primary suspension and a center C of the state of the art. Thus, when the truck passes over track defects (also called "left"), the vertical displacement of the first suspension elements 42 is less than the vertical displacement of conventional primary suspension means. Since the vertical displacement undergoes by the first elements of suspension 42 is reduced, the dimensions of these first suspension elements 42 in the vertical direction Z are reduced compared to those of conventional primary suspension means.
  • the primary suspension means 40 furthermore comprise second suspension elements 44, arranged between the longitudinal members 16 and the axle boxes 32. More particularly, as can be seen in particular in FIG. figure 1 each second suspension element 44 is arranged between one end of a respective one of the longitudinal members 16 and one of the axle boxes 32, this second suspension element 44 being intended to damp a relative rotational movement of the spar 16 and the corresponding axle box 32 around the hinge 36.
  • Each second suspension element 44 comprises for example an arm extending substantially in the longitudinal direction X from the end of the corresponding spar 16, to the corresponding axle box 32, to which it is connected by a pivot connection.
  • Each second suspension element 44 is for example arranged, relative to the vertical direction Z, below the hinge 36 carried by the same end of the spar 16.
  • Each second suspension element 44 is for example formed by a connecting rod.
  • the figure 3 shows two motors 20 which are each carried respectively by one of the crosspieces 17. These motors are arranged in the interior space I delimited by the wheels 14. Each motor is of the "fast" type, that is to say that it operates at a high rotational speed (number of revolutions per minute), and therefore has a small footprint.
  • each motor 20 is connected to at least one of the pairs 12 of wheels 14 via a coupling shaft 22 and a gearbox 24.
  • the coupling shaft 22 of the motor 20 crosses a spar 16 through an opening 21.
  • the coupling shaft 22 extends from the interior of the interior space I towards the outside of this interior space I.
  • the coupling shaft 22 comprises gear coupling means .
  • the gearbox 24 is connected to the support 18 of the frame 15 by means of a reaction rod 25, stabilizing the gearbox 24 vertically at the coupling shaft of the motor 22.
  • the bogie 10 also comprises secondary suspension means 50, carried by the support 18 of the frame 15, at least partially outside the interior space I. More particularly, the secondary suspension means 50 are arranged outside an interior zone delimited in the transverse direction Y between the longitudinal members 16.
  • the highest point of the secondary suspension means 50 is located below the top of the wheels 14 in the vertical direction Z, as shown in FIG. figure 5 .
  • the height of this highest point of the secondary suspension means 50, taken from a support plane of the wheels 14 is for example substantially equal to 700 mm.
  • the secondary suspension means 50 are equipped with support means 52 to the body 60 of the railway vehicle, making it possible to receive all the vertical forces exerted by the body 60 on the bogie 10.
  • the structure of the bogie 10 according to the invention allows the arrangement of the secondary suspension means 50 to a height less than that of the state of the art.
  • the body 60 of the railway vehicle thus comprises at least one access door 62 arranged in line with the bogie 10 (as shown in FIG. figure 7 ).
  • the maximum height of a floor at the foot of the door is 850 mm, measured from the support plane of the wheels 14 (thus from the rails).
  • the height of the door 62 is compatible with the height of a conventional platform, which ensures passengers to easily get on and off the rail vehicle.
  • the longitudinal displacement of the doors 62 to the right of the bogies 10 makes it possible to arrange a two-stage central portion B over a greater length than the central portion A of the conventional vehicle ( figure 6 ).
  • the railway vehicle of the invention therefore has two levels longer, and therefore has a greater capacity for passenger transport.
  • the invention could be applied to a bogie carrier, not including a motor.
  • joints 36 between the side members 16 and the axle boxes 32 could have another structure than that which has been previously described.
  • the bogie 10 could equip any other railway vehicle that a regional express transport train, for example a tramway, metro or a mainline train.
