Definitions

  • the present invention relates to a device for maintaining a trajectory of a guided vehicle during a derailment and / or clearance of said guided vehicle, according to the preamble of claim 1.
  • Guided vehicle refers to commuting means such as buses, trolleybuses, trams, subways, trains or train units, etc., but also means of carrying loads such as, for example, cranes, for which the safety aspect is very important and for which guidance is provided in particular by a single rail.
  • the latter serves as a guide for a guide member which generally bears on the rail and follows its path during the movement of the guided vehicle.
  • the guide member allows for example a guide system to direct a steering axle of the vehicle along the path defined by the rail, said axle being for example provided with load wheels.
  • a first known variant of the guide member comprises a pair of guide wheels, also called guide rollers, mounted in V and provided with lugs for gripping the guide rail.
  • a guiding member is for example described in the documents US 7,228,803 B2 , US 6,029,579 Al , US 6,363,860 B1 .
  • Such a guiding member securely protects the guidance of the vehicle until it stops. It allows for example to avoid material damage that could come from a loss of guidance, and preserve the physical integrity of staff or passengers embarked in the case of public transport.
  • Vehicles guided by this type of guiding device operate according to the following general principle, with reference to the Figure 1 said guide member follows the rail 3 by means of the pair of rollers 1, 2 in contact with the rail 3 and controls the guide system a direction to impose a steering axle of the vehicle.
  • the guide rail 3 is in particular composed of a sole 4 fixed to the ground 5 and a core 6 supporting a mushroom 7 on which the rollers 1, 2 are supported via a tread 9.
  • Each of the rollers 1, 2 of the same pair of guide rollers and has its tread 9 in contact with a surface of the mushroom 7, called rolling surface 8 and symmetrically distributed on either side of the upper part of the mushroom 7.
  • the rollers 1, 2 are in contact with the mushroom 7, and their respective lugs 10 surround non-contact in nominal mode, the latter and approach the core 6 below it.
  • the distance between the lower ends 201, 101 of the two lugs 10 surrounding the mushroom 7 is less than the width C of the mushroom 7, an extraction of the mushroom 7 out of the grip of said rollers 1, 2, or out of the zone between the treads 9 and the lugs 10, is possible only if the angle of attachment of the rollers, ie the angle corresponding to the sector formed by the axes of rotation of each of the rollers 1, 2 of a pair of rollers and which is cut by the plane of symmetry of the pair of V-shaped rollers, increases and / or if the chins 10 and / or the outer edges of the mushroom 7 are deformed.
  • the correct orientation of the vehicle is thus obtained by coupling the pair of rollers of the guide member of the guide system with the steering axle of the vehicle. If the rollers correctly enclose the guide rail, the vehicle follows the path described by the rail during its movement. On the other hand, if the rollers come out of their normal position operation, for example, if the mushroom of the guide rail comes out of the area between the treads and the chins, then the vehicle may leave the path initially established by the rail. Indeed, as soon as the rollers are no longer subject to the direction imposed by the guide rail, they can move to the right or left of the rail, thus deviating the vehicle from the intended path.
  • the scenario in question is defined as a loss of guidance or simply deguidage of the vehicle. In other words, the correct positioning of the rollers is a necessary condition to ensure the correct direction of the vehicle.
  • a second variant of the guide member is described in the document WO 20008/074942 A1 and consists of a pair of rollers enclosing a mushroom, as described above, but with the difference that the rollers are devoid of the chins.
  • the chins of the wheels are replaced by fixed and integral pegs to a base for fixing the rollers, the latter being further protected by a safety shield.
  • This configuration provides a higher rigidity which increases the effort required for the rollers to be extracted from the rail.
  • the extraction of the mushroom out of the grip of the rollers is possible. This is the case, for example, when a vertical upward pulling force is applied to the rollers or to a base for fixing the rollers so that a deformation of the pieces (latch and / or fungus and / or axis of the rollers) makes the distance between the net chin exceeds the width of the mushroom.
  • the rollers no longer clamp the rail and can be positioned next to the latter, as well as presented in Figure 2 , either on the guide rail, as illustrated by the Figure 3 , the references used in Figure 1 being repeated for the figures 2 and 3
  • the guide rollers are positioned next to the guide rail, a deflection of the load wheels may cause the guided vehicle to exit its originally planned trajectory, which may have adverse consequences for the operation of the vehicle and the network to which it belongs, as well as for the safety of the passengers and the vehicle. embedded personnel.
  • An object of the present invention is to provide a simple device, safe and reliable, for maintaining the trajectory of a guided vehicle during a derailment or a loss of guidance of the latter.
  • it is in particular to prevent quickly and reliably that the guide system of a guided vehicle can keep its steering power by means of the steering rods in case of loss of guidance and / or derailment.
  • a set of subclaims also has advantages of the invention.
  • the side rails are parallel to the guide rail, they are also adapted to control a displacement of the guided vehicle along said path imposed by the guide rail.
  • the lateral rails may in particular be current or power rails for supplying electrical energy to said guided vehicle, or side rails configured for guiding said guided vehicle. during a derailment or clearance of said guided vehicle by cooperation with a device for maintaining a trajectory according to the invention.
  • said bar is configured to hold the ends of the rollers in position on the guide rail as presented in FIG. Figure 3 or 4 .
  • end of rollers refers in particular to the lug fitted to a roller or wheel, but also to a shield or fairing of rollers which would be supported on the guide rail during a derailment or loss of guidance as schematically illustrated in FIG. Figure 3 when said guided vehicle is equipped with the device for maintaining the trajectory according to the invention.
  • the geometry and structure of the bar, as well as the fixing means of said bar to said guide member in particular allow to transmit to said guide member a direction to follow in order to keep said vehicle guided along the path defined by the rail guidance.
  • said bar and / or said fixing means comprise an insulating material capable of preventing a transfer of electricity from one of said side rails to said guided vehicle during a contact of said bar with said side rail, particularly when the particular case where the side rail is a current rail.
  • said bar may comprise at each of its ends said insulating material, and / or be made of said insulating material and / or at least partially coated with a layer of said insulating material.
  • said guide bar comprises a jaw adapted to surround the mushroom of said rail so as to serve as a flush-stone when used on a correctly guided vehicle.
  • projecting parts of said jaw extend, when using said holding device according to the invention, from and other mushroom, under the latter, the distance separating the ends of said protrusions of the jaw under said mushroom being less than the width of said mushroom so as to prevent an exit of the mushroom of said rail out of the grip of said jaw when using said holding device according to the invention.
  • Said bar has in particular a substantially parallelepiped shape.
  • said bar has at least a portion of one of its ends bevelled, so that for example front view, the overall geometric shape of the bar substantially corresponds to a rectangle on which is superimposed a isosceles trapezoid whose base has a length identical to the length of the rectangle, and the top has a length less than the base.
  • the geometric shape of the bar allows in particular a self-centering of said bar between the side rails during a derailment and / or guiding of the guided vehicle.
  • said bar may in particular comprise at least one of its ends a support wheel configured to bear on one of said side rails during said derailment and / or clearance of said guided vehicle.
  • the fixing means is in particular adapted to fix said bar to a base for fixing a wheel / roller or wheels / guide rollers of the guide member.
  • said fixing means may in particular fix said bar to said guide member rigidly or in a flexible manner, ie so as to damp the transmission to the guiding member of a shock of an object with said bar.
  • the fixing means preferably comprises a shock absorbing device, comprising for example a hydraulic damping system and / or spring.
  • the present invention also relates to a guide member of a guided vehicle comprising said device for maintaining a trajectory as previously described, said member being in particular characterized in that it comprises a pair of said V-shaped guide wheels to point pointing downwards and provided with chins for gripping the guide rail.
  • the present invention also relates to a guided vehicle comprising said holding device as described above.
  • the Figures 1 to 3 respectively present a correct braking of a pair of rollers 1, 2 on a guide rail 3 representing the nominal mode of operation of the pair of rollers 1, 2, a derailment case of the pair of rollers 1, 2 next to said guide rail 3, and a case of derailment of the pair of rollers 1, 2 on the guide rail 3, each roller being mounted on a fastening base 12 of the guide member.
  • the derailment of the pair of rollers 1, 2 next to the guide rail 3 can lead to a steering of the guide member may lead to a loss of trajectory for the guided vehicle.
  • said bar 15 is mounted in front of said guide member with respect to a direction of travel S of said guided vehicle, as shown in FIG. Figure 5 and in Figure 6 .
  • Each end 151, 152 of the bar 15 is in particular curved in a direction opposite to the direction of displacement S of said vehicle, or may simply comprise an insulating tip, metallic or not.
  • a fastening means 16 may for example make said bar 15 integral with a fastening base 12 of the rollers of the guide member.
