Definitions

  • the present invention relates to a bogie with steerable axles intended to be mounted under the body of a railway vehicle of metro or tram type, this bogie being motor or carrier.
  • the present invention relates to a bogie provided with an axle orientation mechanism which does not encumber the center of the bogie and in which the chassis rests on the axle boxes by elastic elements which, while allowing orientation axles and their return provide the primary suspension.
  • This arrangement ensures effective filtering of vibrations between the bogie chassis and the axle boxes, this advantage being especially noticeable in the low frequency range.
  • the axle orientation mechanism in some cases ensures the transmission of traction and braking forces between the axles and the bogie chassis.
  • the bogie according to the invention is pivotally mounted under a body of a railway vehicle and it comprises a bogie frame carried by axles provided with axle boxes and which can be oriented by an articulated system operated by the relative rotation of the body. It is characterized by the fact that the chassis is supported on each axle box by two elastic support elements made at least partially of elastomer and mounted respectively above and below the axle box, a second articulated system connecting two axle boxes so that they have to pivot around the vertical axes of symmetry of the axles.
  • Each elastic support element consists of two elastomer blocks arranged in a chevron symmetrically with respect to a longitudinal plane perpendicular to the axis of the axle and centered on the vertical plane passing through this axle axis.
  • Each articulated system consists of a control lever pivotally mounted on the chassis and articulated with two connecting bars each coupled by an articulation to an axle box.
  • the bogie comprises a bogie frame 1 which is carried by two axles 2 each consisting of two wheels joined by an axle. Each axle is equipped with two axle boxes 3. The vertical axis of symmetry and orientation of each axle, located at equal distance from the wheels, is marked 22.
  • the body of the vehicle rests on the bogie via a swivel ring 71 which is coaxial with the central vertical axis 13 of the bogie.
  • This crown consists of two rings which can pivot by means of bearings, one relative to the other, around the central axis 13, one of the rings being secured to the body, the other ring being secured a cross member 72 which bears at its ends on the bogie frame by means of two springs 73 forming the secondary suspension.
  • the bogie frame is connected to each axle box by two elastic support elements 4, 8 mounted one below the other so that one, 4, is located above the box d axle and the other, 8, is located below.
  • Each support element 4 or 8 is arranged so as to be symmetrical with respect to the vertical plane passing through the axis of revolution 23 of the axle and with respect to a longitudinal plane perpendicular to this same axis.
  • the bogie frame 1 forms on each side of each axle box two branches on which the elastic support elements 4 and 8 are supported.
  • Each elastic support element 4 or 8 consists of two elastic blocks 41-42 or 81-82 made at least partially of elastomer and each mounted between a support face 311-312 or 321-322 of an inner frame 31 or 32 secured to the axle box and a bearing face 111-112 or 121-122 of an external frame 11 or 12 secured to the chassis.
  • These bearing faces are inclined so as to form V with respect to a plane lon gitudinal which is perpendicular to the axis of revolution 23 of the axle. or
  • the bearing faces 111-112 / are symmetrical with respect to this longitu-or 321-322 dinal plane as well as the bearing faces 311-312.
  • the blocks of the same support element are arranged so as to form a truncated chevron symmetrically with respect to the abovementioned longitudinal plane.
  • the fictitious edges of the ap-or 121-122 and stitched faces, in then 111-112 / and 311-312 or 321-322 are horizontal the plane of symmetry which is perpendicular to the axis of revolution 23 of the axle.
  • the vertical passing through 23 centers of the blocks 41-42 and 81-82 are centered in the plant. This arrangement in V or chevrons, ensures the radial or transverse guiding while allowing the orientation around the axis 22.
  • Each elastic block 41 or 42 has a one-piece or laminated sandwich-type structure which is produced by elastomer plates separated by metallic intermediate plates, these plates, arranged alternately, being bonded together.
  • the blocks are arranged so as to provide a space 43 between the outer frame 11 and the inner frame 31.
  • An elastomer stop 44 is adhered to the frame 11 on the side of the frame 31 This stop ensures the limitation of the vertical clearance of the two frames relative to each other.
  • Each element also includes stops limiting the rotational travel of the axle around the axis 22.
  • the orientation of two axles is controlled by two articulated systems which each connect two axle boxes 3 located on the same side of the median longitudinal plane of the bogie.
  • Each articulated system imposes on the two associated axle boxes angular rotations of opposite directions around the axes of symmetry. In the curve, one of the axles is rotated clockwise while the other axle is rotated counterclockwise, the axes thus becoming convergent.
  • the two articulated systems impose on the two axle boxes 3 located on the same side of the longitudinal axis of the bogie equal and opposite displacements and impose on the two axle boxes 3 of the same axle equally and opposite displacements .
  • Each articulated system comprises a control lever 5 which is articulated around an axis 51 on the bogie frame 1.
  • the two levers 5 are mounted on either side of the vertical vertical plane passing through the axes 22.
  • Each lever 5 is connected to the two axle boxes 3 by link bars 31.
  • Each link bar 31 is coupled to an axle box 3 by a joint 311 located in the horizontal plane passing through the axes axle and by an articulation 52 to a lever 5.
  • each control lever 5 around its axis 51 is controlled by the pivoting movement of the body around the central axis 12.
  • the body has two operating points 61 which describe a circle, around the axis central 12, when the body pivots.
  • Each maneuvering point 61 of the body is coupled to an maneuvering point 53 of a control lever 5 by means of a link allowing the vertical movements of the body-bogie chassis and allowing the body and the body to rotate control lever around their respective axes of rotation.
  • Each link coupling an operating point 61 of the body and an operating point 53 of the control lever is constituted by a connecting rod 6, the operating points 61 and 53 being ball joints which allow the relative vertical deflections of the body and bogie.
  • Each control lever 5 oscillates around a substantially horizontal axis 51, in a substantially vertical plane.
  • the operating points 61 and 53 and the connecting rods 6 are then positioned substantially at the level of the pivoting crown and at a short distance from the body. Because of the springs 73 of the secondary suspension, the control levers 5 are offset from the transverse plane passing through the axis 13, the bars 31 therefore having unequal lengths.
  • the motor bogie which is represented in the figures comprises two motors which is suspended on the chassis and each drive an axle.
  • the parallelism of the two axles is given by the elastic elements 4 and 8 by the control levers 5 which are coupled to the body.
  • the first axle 2 approaching a curve receives a lateral stress coming from the external rail which directs the bogie according to the position perpendicular to the longitudinal axis of the track.
  • the elastic elements 4 and 8 undergo, in the longitudinal plane, displacements which depend on the radius of the curve taken by the bogie.
  • the elastic blocks are precompressed and work in shear.
  • the structure of the elastic elements 4 and 8 allows the angular pivoting of each axle around its vertical axis 22 while ensuring transverse guidance relative to the bogie chassis.
  • the rotation of the body with respect to the first bogie which engages in the curve also implies a rotation of the body with respect to the next bogie.
  • This relative rotation controls the levers 5 of the next bogie and therefore the orientation of the axles of this bogie.
  • the problem of entering the curve is made easier by the fact that the connection between the straight line and the circular portion of the track is effected by means of a parabolic portion.
  • the elastic elements 4 and 8 exert a restoring torque which tends to reposition the axle in the transverse position.
  • the rotation of the body to its initial position along the longitudinal axis of the bogie brings the control levers 5 back to their initial positions.
  • the traction and braking force between the axles and the bogie chassis is transmitted, via the bars 31, to the control levers 5 which are linked to the bogie chassis by the joints 51.
  • the traction force or applied to the bogie chassis is transmitted to the body via the slewing ring.
  • the articulated systems are designed to simultaneously support the traction or braking forces and the orientation efforts of the axles. In curves, the orientation forces of the axles in the orientation mechanism come into play, in addition to any traction or braking forces. At this time these orientation efforts occur in proportion to the angles at which the axles have pivoted.
  • the first car that enters a curve drives the second car by its hitch, gradually orienting its first and second bogie and so on.
  • the bogie could have three axles, the middle axle being guided around a fixed axis relative to the bogie chassis and the two outer axles being oriented as in the embodiments described above.
  • the upper 4 and lower 8 elastic elements can be produced with elastic blocks of different or identical compositions and dimensions.
  • the bogie chassis could include closed frames each surrounding an axle box and serving to support elements 4 and 8.
  • axle boxes instead of being placed outside the wheels, could be placed between the wheels, the side members of the bogie chassis then extending between the wheels.
