Definitions

  • the present invention relates to a connection assembly between a vehicle body and a bogie chassis, provided in particular for ensuring the drive of the body with respect to the bogie chassis.
  • the invention also relates to a railway vehicle comprising such a connection assembly.
  • Known linkage assemblies such as the one shown in the figure 2 of the document DE-PS- 667,024 for example, generally involve two lateral drawbars arranged on either side of the bogie chassis and connecting the vehicle body to the bogie chassis.
  • a transverse balancing bar ensures equal traction forces on the two traction bars by connecting one end of each of the traction bars.
  • Such a connection assembly ensures an articulated force transmission between the vehicle body and the bogie chassis, allowing the rolling of a railway vehicle on the curved rails of small radius and of avoiding loss of control.
  • the link between the link assembly and the bogie frame is generally made by one or more pivot link members interposed between the drawbar and the bogie frame.
  • the pivot connection member (s) and the balancing bar are generally located in the volume delimited by the bogie itself, which implies problems of space requirement on recent systems, in which other devices are present at this point. place because the pivot connecting members and the known balancing bars having a large bulk.
  • One of the objects of the invention is to propose a connection assembly between a vehicle body and a bogie chassis whose space in the bogie is reduced compared to the systems of the prior art.
  • connection assembly according to claim 1.
  • the pivot connecting members and the balancing bars being placed outside the volume of the bogie chassis, space is available for the integration of other devices under the bogie chassis.
  • connection assembly comprises one or more of the characteristics defined in claims 2 to 5.
  • the invention also relates to a railway vehicle comprising a body, a bogie having a chassis, and a connection assembly as defined above, the body being connected to the chassis via the connection assembly.
  • Link assembly 2 of the figure 1 connects a body 4 of a vehicle 6 to a chassis 8 of a bogie 10 of this vehicle 6.
  • the body 4 is vertically supported on the chassis 8 by means of the connection assembly 2 which connects the body 4 to the chassis 8.
  • the vehicle 6 is a guided land vehicle, intended to move longitudinally along a track while being guided transversely along the latter by its bogie 10.
  • the vehicle 6 is here more particularly a railway vehicle, intended to move along a railway track (not shown) comprising two parallel rows of rails.
  • the terms “longitudinal”, “transverse”, “vertical”, and “horizontal” are understood to mean the vertical direction of support of the body 4 placed on the bogie 10 and the direction longitudinal and horizontal movement 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.
  • connection assembly 2 is configured to support the body 4 vertically with respect to the bogie 10.
  • the connection assembly 2 is also configured to link the body longitudinally and transversely to the bogie 10.
  • the bogie 10 comprises at least one axle, here two axles 12, supporting the chassis 8, preferably by means of a primary suspension (not shown).
  • Each axle 12 has a pair of coaxial wheels 14 linked in rotation by an axle shaft 15.
  • the axle shaft 15 of each axle 12 is here coaxial with the wheels 14, is linked in rotation to the wheels 14, each wheel 14 being mounted on a respective end of the axle shaft 15.
  • the connecting assembly 2 comprises two traction bars 22 and 24 provided respectively on either side of the chassis 8. At one end, the traction bars 22 and 24 are connected, by means of a connecting member ball joint 25 and 26, to the chassis 8.
  • ball joint member means a mechanical device comprising at least two parts movable relative to each other according to at least three orthogonal axes of rotation.
  • the ball joint connecting members 25 and 26 are preferably spherical bearings with an elastomer cushion.
  • the drawbars 22 and 24 are connected to each other by a balancing bar 28 and extending generally transversely with respect to the drawbars 22 and 24.
  • the connection between the bars traction 22 and 24 and the balancing bar 28 is produced by two ball joint members 29 and 30, preferably formed by spherical bearings with an elastomer cushion.
  • the balancing bar 28 is connected to the vehicle body 4 by a pivot link member 32.
  • pivot link member means a mechanical device comprising at least two parts movable relative to each other around a single axis.
  • the pivot link member 32 allows relative rotation about the Z axis between the balancing bar 28 and the vehicle body 4.
  • the pivot link member 32 is advantageously provided in the center of the balancing 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 link member 32 are located under the body of the vehicle 4 opposite a front edge 17 of the chassis 8, facing the front of the rail vehicle 6 relative to its direction of travel.
  • This structure is particularly advantageous in the case where the vehicle body 4 is provided with a central structural beam 41 on which the structure of the vehicle body 4 is built.
  • the pivot connecting member 32 can be directly secured to the central beam 41.
  • connection assembly 2 also includes an additional balancing bar 34 connecting the traction bars 22 and 24 to each other at a distance from their respective ends.
  • connection assembly 2 allows a significant saving of space in the center of the chassis 8 for additional equipment. This structure also makes it possible to provide bogies of reduced dimensions and therefore a saving in weight.
  • connection assembly 102 also makes it possible to improve the operating performance of the bogie, in particular by providing a smoother entry into the curve with a better distribution of the guide forces, a reduction in wear in the curves, the straight lines and curved entries, a smooth inscription in tight curves, and improves stability by reducing hunting at high speed.
  • a second embodiment is shown in 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 from the first embodiment are detailed in the following.
  • connection assembly 102 comprises two pivot connection members 132 and 133 connecting the traction bars 122 and 124 to the vehicle body 104. More specifically, each of the traction bars 122 and 124 is connected to the pivoting 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 drawbars 122 and 124, as well as to the balancing bar 143, by ball joint connecting 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 link member 132 and the bar 140b connects the pivot link member 132 to the ball joint member 147.
  • the bar 141a connects the ball joint member 146 to the pivot link member 133 and the bar 141b connects the ball joint member 133 to the ball joint member 148.
  • the ball joint members 145 to 148 are spherical bearings with elastomer cushions.
  • This structure allows, as is the case in the first embodiment, to free up an important place under the bogie frame 110 for additional equipment.
  • This structure also makes it possible to obtain the advantages of stability and behavior in operation listed above with reference to the first embodiment.
  • the pivot connecting members 132 and 133 are located in the extension of the longitudinal edges 108a and 108b of the bogie frame 108.
  • the pivoting members 132 and 133 are adapted to be secured to two structural beams 150 and 151 longitudinal sides of the vehicle body 104 on which the structure of the body 104 is built.
  • Such a structure is particularly suitable for vehicles made in part of aluminum such as, for example, passenger rail transport cars.
  • additional damping can be obtained by using spherical bearings with hydraulic damping controlled on the basis of the vibration frequency induced by the rolling speed, at the level of the ball joint connecting 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 drawbars 22 and 24 can be arranged relative to each other in a non-parallel manner, the ends of the drawbars 22 and 24 in this case forming a trapezoid and not a parallelogram. Such an arrangement makes it possible to increase the possibilities of rotation around the axis Z-Z ′ of the bogie chassis relative to the vehicle body.
