Definitions

  • This bogie is mainly constituted by a supporting chassis supporting the body.
  • the connections between the wheels and the chassis by articulated arms are obtained by elastic joints according to an arrangement well known in automotive and railway technology.
  • these articulated arms (or pulled arms) have the particularity of being able to constitute the transmission casings themselves and of supporting the traction motor which is thus completely suspended.
  • FIG. 1 shows schematically a bogie with four independent wheels according to the invention.
  • This bogie comprises a transverse supporting frame 1 consisting of a cross member 2 terminated, at each end, by a horizontal beam 3 and perpendicular to the cross member giving the frame the general shape in capital letter I.
  • the connections between the wheels 4 and the chassis 1 are produced by articulated arms 5.
  • An elastic articulation 6 provides the connection between each arm 5 and the corresponding end of a spar 3.
  • the arms articulated 5 are intended to support the traction motors of the wheels. They also constitute the transmission housings between the motors and the wheels. The motors are thus completely suspended.
  • the invention makes it possible to design a particular suspension for the bogie. It is indeed possible to functionally separate the actual suspension taking up the tare weight of the vehicle and the additional leveling suspension subjected to the variable load of the vehicle loaded by the travelers.
  • This separate suspension is achieved by members which, although different, may be located close to each other.
  • the tare weight of the vehicle is taken up by the suspension members 7 which can be helical springs, torsion bars or rubber-metal assemblies.
  • the additional leveling suspension is provided by a suspension member 8.
  • the suspension members 7 and 8 can be located horizontally and laterally between vertical consoles 9 secured to the articulation arms 5 near the articulations 3. As shown in the figure 1, these suspension members are placed parallel to the rails.
  • the drive and the rotation of the body can be ensured by conventional means such as longitudinal connecting rods and an orientable pivot crown.
  • FIG 2 is a perspective view of a hinge arm 5.
  • the fork comprises a first branch 51 and a second branch 52 connected by an end spacer 53.
  • the two branches 51 and 52 are of different dimensions.
  • the branch 51 occupies a larger volume than the branch 52 because it is intended to contain the transmission members between the motor and the wheel.
  • the branches 51 and 52 respectively comprise bearings 54 and 55 located on the side of the spacer 53.
  • the articulation of the arm on the chassis can be done by means of an axis passing through the bearings 54 and 55 as well as a bearing 31 located at the end of the side member 3 of the chassis.
  • the articulation bearings can advantageously be produced by rubber-metal parts capable of resisting elastically the forces driving the arm during the application of the traction and braking torques, and the transverse forces due to the guiding of the wheel. on the way.
  • the fork rests on the two spindles of the wheel, which is engaged in the fork, by means of bearings.
  • the free ends of the arms 51 and 52 can be separated from the rest of the arm according to joint planes 56 and 57 passing through the axis of the wheel so as to be able to mount and dismount the latter.
  • the cradle is the part that supports the traction motor. It is located near the joint and braces the two branches. It can be constituted by a metal plate disposed between the two branches or by spacers, one of which can be the end spacer 53.
  • the engine can be fixed by screws.
  • the motor will be fixed on the cradle so that the axis of the motor can drive a set of pinions located inside the branch 51 which then serves as a casing.
  • the motor will advantageously be arranged so that its axis is horizontal and transverse relative to the wheel.
  • FIG 3 there is shown a part of a bogie comprising a train of wheels 4 placed in the housings formed by the articulation arms 5.
  • the arms 5 are articulated to the carrying frame 1 by elastic joints not shown.
  • the axis 21 of a motor 20 rotates, by the through a set of pinions 22, the spindle 42 of the corresponding wheel 4.
  • Each torsion bar 70 is fixed on one side to a projection 12 from the central part of the chassis and on the other side to an articulation arm 5.
  • the torsion bars 70 serve as tare suspension members of the vehicle and therefore play the same role as the members referenced 7 on the Figure 1.
  • the additional suspension members 8, shown as pneumatic elements, are placed between supports integral with the suspension arms. These members 8 can also be formed by other elastic elements with variable flexibility such as rubber and metal blocks, hydraulic or hydro-pneumatic cylinders.
  • the supports of these bodies can be consoles as is briefly shown in Figure 1 where they can be formed by the traction motors themselves.
  • This arrangement of functionally separate suspensions results in a small overall height.
  • it allows a more favorable dimensioning of the components as well as the associated fluid sources since the additional suspension only supports part of the total load.
  • the braking system can comprise disks 40 fixed on the rockets 43 of the wheels 4.
  • Calipers 41 supporting the actuators of the brake shoes, can be fixed on the traction motors themselves.
  • the braking assembly itself is completed by an electromagnetic braking pad resting on the two arms pulled between the wheels of the same file of rails.
  • Figure 4 we recognize a wheel 4 of the bogie, its articulation arm 5 visible by the branch 51, the elastic articulation 6 of the arm on the chassis 1.
  • the frame 1 supports the cross-member 10 by means of the elastic block 11.
  • the articulation arms 5 can support an electromagnetic pad 32 by file of rails.
  • the bogie according to the invention makes it possible to design a particularly advantageous arrangement for ensuring the vertical suspension.
  • This arrangement is shown in Figure 5 where the same references as in the previous figures represent the same elements.
  • the load cross member 10 is integrated into the additional suspension of leveling to constitute midpoints with complementary suspension springs 81 whatever their nature.
  • This arrangement makes it possible to balance the load cross member itself disposed on the transverse suspension blocks 11, and to transmit the drive forces elastically by the suspension itself.
  • the references 13 designate the elements of the crossmember intended to serve as midpoints for the complementary suspension springs.
  • FIG. 6 which is a detailed view of the bogie shown diagrammatically in FIG. 5, these elements are designated by the references 130.
  • These elements can be metal studs attached to the load cross member.
  • the console 91 on which a part of the suspension member 81 is fixed, is otherwise arranged on the motor 20.
  • the additional suspension members are jacks 82 exerting their action between the studs 131 attached to the load cross member and the brackets 92 integral with the motors.
  • the load cross member 10 is an airtight container comprising a lower face 61 integral with the transverse suspension blocks 11, an upper face 62 supporting the body, two lateral faces 63 and 64, each having a central hole and two membranes 65 and 66 pierced with a central hole and forming pneumatic cushions.
  • the membranes 65 and 66 are fixed in their centers to two tubular supports 71 and 72 fixed respectively on the consoles 93 of the traction motors by their bottom 73 and 74.
  • the membranes 65 and 66 are hermetically connected and respectively to the upper 62 and lower faces 61 by fasteners 67 shown by axes.
  • the box includes a device making it possible to obtain inside a variable pressure proportional to the spacing between the consoles.
