Definitions

  • the present invention relates to a connection assembly between a vehicle body and a bogie frame, provided in particular for ensuring the drive of the body relative to the bogie frame.
  • the invention also relates to a railway vehicle comprising such a link assembly.
  • connection assemblies generally involve two lateral traction bars arranged on either side of the bogie frame and connecting the vehicle body to the bogie frame.
  • a transverse balancing bar ensures equal traction forces on the two drawbars by connecting one end of each of the drawbars.
  • Such a link assembly provides a power transmission articulated between the vehicle body and the bogie frame, allowing the rolling of a railway vehicle on the rails in curve of small radius and to avoid loss of control.
  • the link between the link assembly and the bogie frame is generally made by one or more pivot connecting members interposed between the drawbar and the bogie frame.
  • the pivot connecting member (s) and the balancing bar are generally located in the volume defined by the bogie itself, which implies congestion problems on recent systems, in which other devices are present at this point. place, because the pivot connecting members and balancing bars known having a large footprint.
  • One of the aims of the invention is to propose a connection assembly between a vehicle body and a bogie frame whose space in the bogie is reduced compared to the systems of the prior art.
  • the invention proposes a connection assembly between a vehicle body and a bogie frame comprising two traction bars positioned on the sides of the chassis each comprising an end connected to the body via a ball joint member and one end. linked to the chassis via a ball joint member, and a balancing bar transversely connecting the drawbars.
  • This link assembly is characterized in that the balancing bar is positioned outside the bogie frame, and connected to the vehicle body by at least one pivot connecting member positioned outside the bogie frame.
  • the pivot connecting members and balancing bars being placed outside the volume of the bogie frame, room is available for the integration of other devices under the bogie frame.
  • the invention also relates to a rail vehicle comprising a body, a bogie having a frame, and a link assembly as defined above, the box being connected to the frame via the link assembly.
  • the link assembly 2 of the figure 1 connects a body 4 of a vehicle 6 to a frame 8 of a bogie 10 of this vehicle 6.
  • the body 4 is supported vertically on the frame 8 via the link assembly 2 which connects the body 4 to the frame 8.
  • the vehicle 6 is a guided land vehicle, intended to move longitudinally along a track being guided transversely along it by its bogie 10.
  • the vehicle 6 is here more particularly a railway vehicle, intended to move along a railway (not shown) comprising two rows of parallel rails.
  • the terms “longitudinal”, “transverse”, “vertical”, and “horizontal” refer to the vertical bearing direction of the body 4 placed on the bogie 10 and to the direction longitudinal and horizontal displacement of the bogie 10 along the track.
  • the bogie 10 is provided to support the body 4 vertically and to guide it transversely along the track.
  • the link assembly 2 is configured to support the body 4 vertically relative to the bogie 10.
  • the link assembly 2 is also configured to bind the box longitudinally and transversely to the bogie 10.
  • the bogie 10 comprises at least one axle, here two axles 12, supporting the frame 8, preferably via a primary suspension (not shown).
  • Each axle 12 has a pair of coaxial wheels 14 rotatably connected by an axle shaft 15.
  • the axle shaft 15 of each axle 12 is here coaxial with the wheels 14, is rotatably connected to the wheels 14, each wheel 14 being mounted on a respective end of the axle shaft 15.
  • the link assembly 2 comprises two traction bars 22 and 24 respectively provided on each side of the frame 8. At one end, the traction bars 22 and 24 are connected, via a link member ball 25 and 26, the frame 8.
  • ball joint member is meant a mechanical device comprising at least two movable parts relative to each other in at least three orthogonal axes of rotation.
  • the ball joint members 25 and 26 are preferably spherical bearings with an elastomeric cushion.
  • the drawbars 22 and 24 are connected to each other by a balancing bar 28 and extending generally transversely to the drawbars 22 and 24.
  • the connection between the bars of traction 22 and 24 and the balancing bar 28 is made by two connecting members ball 29 and 30, preferably formed by spherical bearings with elastomeric cushion.
  • the balancing bar 28 is connected to the vehicle body 4 by a pivot connecting member 32.
  • pivot connecting member is meant a mechanical device comprising at least two parts movable relative to each other around one axis.
  • the pivot connecting member 32 allows relative rotation about the Z axis between the balancing bar 28 and the vehicle body 4.
  • the pivot connecting member 32 is advantageously provided in the center of the balance bar 28 .
  • the balancing bar 28 and the pivot connecting member 32 are positioned outside the frame 8.
  • the balancing bar 28 and the pivot connecting member 32 are located outside the space delimited by the horizontal contours of the chassis 8.
  • the balancing bar 28 and the pivot connecting member 32 are located under the body of the vehicle 4 facing a front edge 17 of the chassis 8, facing the front of the railway vehicle 6 relative to its direction of movement.
  • This structure is particularly advantageous in the case where the vehicle body 4 is provided with a central structure beam 41 on which the structure of the body of the vehicle 4 is constructed.
  • the pivot connecting member 32 can be directly secured to the central beam 41.
  • the linkage assembly 2 also includes an additional balancing bar 34 connecting the pull rods 22 and 24 to each other at a distance from their respective ends.
  • connection assembly 2 allows a significant space saving in the center of the chassis 8 for additional equipment. This structure also makes it possible to provide bogies of reduced dimensions and consequently a gain in weight.
  • the structure of the link assembly 102 also makes it possible to improve the operating performance of the bogie, in particular by providing a smoother entry in the curve with a better distribution of the guiding forces, a reduction in the wear in the curves, the Straight lines and curved entrances, a gentle inscription in tight curves, and improves stability by reducing hunting in high speed.
  • a second embodiment is shown on the figure 2 .
  • the elements common to the first embodiment have the same reference increased by 100 and operate in the same way. Only the differences with respect to the first embodiment are detailed in the following.
  • the linkage assembly 102 comprises two pivot link members 132 and 133 connecting the pull rods 122 and 124 to the vehicle body 104.
  • each of the pull rods 122 and 124 is connected to the pivot members 132 and 133 by mechanical parts 140 and 141 articulated on the pivot connecting members 132 and 133 and connected to each other by a balancing bar 143.
  • the parts 140 and 141 are parts of triangular shape connected to the pull rods 122 and 124, as well as to the balance bar 143, by ball joint members 145, 146, 147, and 148.
  • the parts 140 and 141 are formed by three vertices connected by two respective bars 140a, 140b and 141a, 141b.
  • the bar 140a connects the ball joint member 145 to the pivot connecting member 132 and the bar 140b connects the pivot connecting member 132 to the ball joint member 147.
  • the bar 141a connects the ball joint member 146 to the pivot connecting member 133 and the bar 141b connects the pivot connecting member 133 to the ball joint member 148.
  • the ball joint members 145 to 148 are spherical bearings with elastomeric cushions.
  • This structure allows, as is the case in the first embodiment, to release a large space under the bogie frame 110 for additional equipment. This structure also makes it possible to obtain the stability and operating behavior advantages listed above with reference to the first embodiment.
  • the pivot link members 132 and 133 are located in the extension of the longitudinal edges 108a and 108b of the bogie frame 108.
  • the pivot members 132 and 133 are adapted to be secured to two longitudinal structural beams 150 and 151 of the body of vehicle 104 on which the structure of the body 104 is constructed.
  • Such a structure is particularly suitable for vehicles made in part of aluminum such as, for example, passenger rail cars.
  • additional damping can be obtained by using spherical bearings with controlled hydraulic damping on the basis of the vibration frequency induced by the rolling speed, at the level of the ball joint members 25, 26, 29 and 30 for the first embodiment of the invention and 125, 126, 145, 146, 147, 148 for the second embodiment of the invention.
  • the pull rods 22 and 24 may be arranged relative to each other in a non-parallel manner, the ends of the pull rods 22 and 24 forming in this case a trapeze and not a parallelogram. Such an arrangement makes it possible to increase the possibilities of rotation around the axis ZZ 'of the bogie frame with respect to the vehicle body.
