Definitions

  • the present invention relates to a bogie with steerable axles corresponding to the preamble of claim 1 and known from DE-A-2624719.
  • Certain rail vehicles such as metros and trams are required to use curves with very small radii of curvature.
  • the orientation of the axles limits the dynamic stresses applied, transversely, on the wheel flanges. It limits the stresses and the wear of the tubes as well as the noise caused by the contact of the tubes on the rails.
  • 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 characterized in 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 box d 'axle.
  • 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 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 fitted with two axle boxes 3. The vertical axis of synchronization and orientation of each axle, located at equal distance from the wheels, is marked 22.
  • the vehicle body rests on the bogie via a pivot 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, on the central axis 13, one of the rings being secured to the body, the other ring being secured to 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 chassis 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 relative to the vertical plane passing through the axis of revolution 23 of the axle and relative 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 internal 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 longitudinal plane which is perpendicular to the axis of revolution 23 of the axle.
  • the bearing faces 111-112 or 121-122 are symmetrical with respect to this longitudinal plane, as are the bearing faces 311-312 or 321 -322.
  • 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 bearing faces 111-112 or 121-122 and 311-312 or 321-322 are horizontal and contained in the plane of symmetry which is perpendicular to the axis of revolution 23 of the axle.
  • the centers of blocks 41-42 and 81-82 are centered in the vertical plane passing through 23. This arrangement in V or chevrons, ensures the radial or transverse guidance while allowing the autor orientation of the axis 22.
  • Each elastic block 41 or 42 has a one-piece or laminated structure - sandwich type - 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 movement of the autor axle of the axis 22.
  • the orientation of two axles is controlled by two parts of the articulated system which each connect two axle boxes 3 located on the same side of the median longitudinal plane of the bogie. Each part imposes on the two associated axle boxes angular rotations of opposite directions autor 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 parts impose on the two axle boxes 3 situated 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 part comprises a control lever 5 which is articulated with 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 31 located in the horizontal plane passing through the axle axes and by an articulation 52 to a lever 5.
  • each control lever 5 autor of its axis 51 is slaved to the pivoting movement of the body autor of the central axis 12.
  • the body has two operating points 61 which describe a circle, autor of the axis central 12, when the body pivots.
  • Each maneuvering point 61 of the body is coupled to the maneuver 53 of a control lever 5 by means of a link allowing the vertical movements of the body-bogie chassis and authorizing the rotations of the body and the control lever autor of 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 autor an axis 51 substantially horizontal, 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 are 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 elastic elements 4 allows the angular pivoting of each autor axle of 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 line and the circular portion of the track takes place via 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 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 or braking applied to the bogie chassis is transmitted to the body via the swivel ring.
  • the articulated system is 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 comprise three axles, the median axle being guided by an axis fixed 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.
