Definitions

  • the present invention relates to a bogie carrying the body of a railway vehicle, comprising a chassis mounted on wheels of standard diameter and equipped with brakes at least one fixed axle of angled shape allowing the bottom housing of the vehicle floor, serving as support to primary suspension springs and supporting two rockets on which the wheels are mounted, the rockets being located higher than the lower part of the fixed axles.
  • Document FR-A-2 484 940 discloses a carrier bogie placed under the articulated ends of two boxes. An interlocking ring made up of two articulated parts is placed between the boxes and allows the passage from one to the other box. If you wanted to lower the floor, the wheels would have to be smaller than the standard diameter.
  • Document FR-A-2 538 334 describes a two-axle bogie for railway vehicles, comprising a chassis formed by two longitudinal members, the ends of which support in an articulated manner with the aid of elastic annular supports two axles which respectively carry wheels of diameter reduced. Such a bogie does not allow the use of standard diameter wheels.
  • the document FR-A-1,126,807 describes a load-bearing bogie corresponding to the preamble of claim 1, and comprising a chassis mounted on standard diameter wheels and equipped with brakes, a fixed axle of angled shape allowing the bottom housing of the floor of the vehicle, serving as a support for primary suspension springs and supporting two rockets, located higher than the lower part of the fixed axle, and on which the wheels are mounted.
  • the axle has swan neck ends that frame the wheels. It is therefore bulky, complicates assembly and disassembly, and prevents the use of standard diameter disc brakes or other members, such as sensors for measuring rotation, on the external side of the wheels.
  • EP-A-0 058 914 also discloses an articulated tram train, with a lowered floor, in which the carrying bogie is placed, not under the articulation of the boxes but under one of the boxes.
  • the wheels then have a diameter smaller than the standard wheel diameter. As a result, wear is rapid.
  • the brake discs have a diameter limited by the diameter of the wheels.
  • the fleet of spare parts is larger and the maintenance procedures are different.
  • the material does not have the same qualities of stability in the two directions of circulation. The efforts are different on both sides of the joint, the latter transmitting all the efforts of the front body.
  • the object of the present invention is to provide a load-bearing bogie, in particular for a tram, having wheels of standard diameter and making it possible to provide, directly above, a central part of the floor (in the intercirculation half-rings) occupying a lowered position. .
  • the arrangement of disc brakes allows the use of a standard diameter for discs despite the lowered floor. Because this bogie is placed under the intercirculation half-rings, there are the same qualities of rolling stability in the two traffic directions and the vehicles equipped with such a bogie are then bidirectional. Furthermore, the efforts of the boxes are directly transmitted to the bogie without these efforts passing through the joint connecting the two boxes.
  • the wheels are elastic and the arrangement of the brakes promotes assembly and disassembly.
  • the bogie according to the invention is characterized in that it comprises at least two axles constituted by a transverse beam which extends in the lower part and joins two support pieces of the springs, each support piece being arranged on the side internal of the corresponding wheel.
  • the bogie is preferably mounted under an intercirculation assembly mounted between two boxes.
  • a disc brake is advantageously mounted on the outside of each wheel, the disc of which is integral with the wheel and is offset from the latter, said wheel being elastic.
  • the rockets are either integral with the supporting parts, or integral with the wheels and guided by bearings in the supporting parts.
  • the bogie is mounted under the ends of two vehicle bodies.
  • the articulation comprises an intercirculation assembly 6 (in two parts or constituting the central module), which allows the passage of travelers between the boxes.
  • the boxes can pivot relative to each other around a transverse axis and around a vertical axis (relative pivoting in the horizontal plane).
  • the bogie comprises a chassis 1 made up of longitudinal members 11 joined by two cross members 12.
  • the chassis is supported, by means of primary suspension springs 4, on fixed axles 3 which carry the wheels 2.
  • the springs 4 are used for the vertical support of the chassis, for the transverse drive and for the transverse guiding of the axles.
  • Each axle consists of a transverse beam 33 which, by extending in the lower part, two support pieces 32 of springs, each supporting a wheel spindle 31 so that said spindle 31 is located higher than said transverse beam 33.
  • Each axle has a bent shape due to the fact that the top of the transverse beam 33 is located below the axis of the spindle 31. This bent shape allows the housing of the floor of the intercirculation assembly substantially below of the upper rocket generator.
  • the spindles 31 are integral (extending outward) with the support pieces 32.
  • Each wheel 2 is guided on the corresponding spindle by means of roller bearings 25 and 26.
  • the rockets 31 are integral with the wheels and are guided by bearings 25 and 26 in the support parts 32.
  • Each support piece 32 serves as a support for two primary suspension springs 4 which carry a frame beam so as to produce the vertical support, the transverse drive and the transverse guide.
  • each spring 4 is of the sandwich type and supports a spar 11.
  • Each sandwich 4 is constituted, in a manner known per se, by plates of elastomeric material and by intermediate metal plates adhered to the elastomer, the metal plates terminals being fixed respectively to a support piece 32 and to a side member 11 of the chassis.
  • the two sandwiches 4 associated with the same support piece 32 are mounted so that the metal plates are inclined and converge upwards and that the elastomer works in compression and shear.
  • Each support piece 32 has, in side view, a trapezoid shape whose small base is located at the top.
  • a pair of conical springs or a combination of helical metal springs associated with elastomer springs could be envisaged, for example.
  • Each wheel 2 has two elastic damping rings 23 which are sandwiched between rings 21-27 located at the periphery of the wheel disc and the wheel tire 22.
  • This tire 22 is held by the biconical shapes on the outside of the rings 21-27, elastic rings 23 and the bore of the bandage 22.
  • the ring 27 which is removable allows mounting and dismounting.
  • Each wheel is fitted with a disc brake 5 consisting of a brake disc 51 and a caliper 52 carrying the brake pads.
  • the brake disc 51 is secured to the wheel hub via a ferrule 511.
  • the disc is mounted outside of the wheel 2 while being offset relative to the latter.
  • the stirrups 52 are fixed to the bogie chassis.
  • the outside diameter of the disc 51 can be less than the diameter of the bore of the tire 22 so as to facilitate assembly and disassembly.
  • Each wheel is equipped with a rotation measurement sensor 81.
  • This sensor is mounted at the end of the spindle 31 carrying the wheel 2 and is used to measure the rotation of the wheel by providing a signal representative of this rotation to a device for known anti-braking device which controls brake release.
  • the reference assembly 6 is supported, on each side, on a beam 11 of the chassis by secondary suspension springs 7 so as to allow the relative pivoting of the boxes around a transverse axis and a vertical axis.
  • the central body assembly is supported on the side members 11 of the chassis by pneumatic cushions.
  • the central assembly 6 is connected transversely to a cross member 12 of the bogie frame by a transverse damper 92 which is coupled by articulations to the cross member and to the ring.
  • the secondary suspension is associated with a vertical damper 91 which is mounted towards the outside.
