Definitions

  • the invention relates to a bogie with means for traveling on tracks having different gauges and more particularly to a bogie with rotating axles provided with a gauge changing device in cooperation with a changing installation arranged between two tracks having different gauges.
  • that system involves incorporating in railway units a translation device of the wheels of their axles and, on the other hand, a changing installation assembled between the tracks having different gauges.
  • the operation for changing the distance between wheels is performed automatically, without human intervention, with the passage of the train over said installation in five continuously occurring phases; in the first phase, the wheels are released from their vertical loads; in the second phase, the wheel axle assemblies are released from a lateral locking mechanism holding them in their running position; in the third phase, the wheels, which are released from the vertical load and from their lateral lock, enter into guides which, as the axle moves forward, laterally move them to their new running position, in accordance with the new track gauge; in the fourth and fifth phases, the wheel assemblies are laterally locked again and the vertical load is applied to the axle again, thereby concluding the change operation.
  • the axle integrates two independent running assemblies (wheel with short axle or half-axle and two bearings), the gauge change between wheels being performed by the simultaneous transverse movement of the two running assemblies in a manner similar to that used in TALGO trains although, rather than including locking devices in the two bearings of each running assembly, they only incorporate the locking device in the inner bearing.
  • the axle assembly comprises an axle chassis on which are assembled the two running assemblies and their locking systems, a connection device between running assemblies, two translation frames of the brake blocks, an electrical continuity system between the wheels or an electrical shunting system and a device for detecting hot inner bearings.
  • the present invention aims to meet this demand.
  • An object of the present invention is to provide a freight bogie that can adapt to railroad tracks having different gauges in which the non-suspended weight component is minimized.
  • Another object of the present invention is to provide a freight bogie that can adapt to railroad tracks having different gauges in which the track gauge change device is uncoupled from the bearing parts of the platform.
  • Another object of the present invention is to provide a freight bogie that can adapt to railroad tracks having different gauges in which the risk of the accidental unlocking of the device which allows varying the distance between the wheels is minimized.
  • a bogie comprising a bearing platform of a railway wagon and at least one rotating axle on which there are assembled two wheels by means of a coupling device which allows their lateral movement, including bearing parts of said platform with inner bearings, the bogie being provided with a track gauge change device using means which prevent/allow the lateral movement of each wheel such as a lock which is vertically movable when actuated by locking/unlocking guides provided for that purpose in a changing installation for performing the track gauge change, in which:
  • the rotating axle incorporates at its ends bushes and the bearing parts also include a side chassis with support shoes in the changing installation and a central collar serving as support for the end of the axle during the passage through the changing installation through a semicircular bush connected to said central collar.
  • the axle is duly protected during the track gauge change operation.
  • the bogie also comprises a bolt as an additional safety element connected to each lock through a horizontal spring for the purposes of preventing its vertical movement in cooperation with a retaining element of said bolt connected to a bearing part.
  • Another object of the invention is to provide a changing installation to perform the gauge change operation adapted to a bogie provided with means which minimize the risk of the accidental unlocking of the device which allows varying the distance between the wheels.
  • This object is achieved with a changing installation for performing the track gauge change comprising sliding and bearing guides, lateral movement guides and locking/unlocking guides, in which the head of the locking/unlocking guides is configured such that it can laterally move said bolt, overcoming the force of said horizontal spring.
  • the bogie according to the present invention includes:
  • the coupling device for coupling the wheel 1 to the axle 2 comprises a bush 3 integral with the wheel 1 and sliding on the axle 2 including a ring 7 located in the inner part of the axle 2 (i.e., between the wheels), with an axial inner bearing 8, to which the fixing guides 18 are fixed.
  • the bush 3 moves laterally with the wheel 1 involved, the movement of which is limited on one hand by the bush 8' and on the other hand by a grooved bush 5 which transmits the wheel torque to the rotating axle 2.
  • the bush 3 is introduced inside the tubular element 29 until its end body 4 reaches the stop established by the grooved bush 5.
  • the fixing bodies 20 include housings to receive said fixing guides 18 as well as stops provided to serve as positioning and insertion means for the lock 22.
  • the central part of the axle 2 on which the wheels 1 are located in the positions corresponding to the two track gauges by means of the coupling device which has been described as well as the track gauge change device, has a larger diameter than that of its end parts.
  • the bush 8' serving as a stop for the movement of the bush 3 is arranged in the area of transition between the two gauges.
  • At the ends of the axle 2 there is arranged a bush 13 together with a cover 15 fixed to the axle 2 by means of screws serving as a protective element for the same during the track gauge change operation as well as for the stop of the bearings 12.
  • the bearing parts 10 also include a side chassis with support and sliding shoes 16 in the changing installation, for which purpose they have nylon guides 17 and a central collar serving as support for the end of the axle 2, covered by the bush 13, during the passage through the changing installation through a semicircular bush 14 connected to said central collar which is preferably made of bronze.
  • a side chassis with support and sliding shoes 16 in the changing installation, for which purpose they have nylon guides 17 and a central collar serving as support for the end of the axle 2, covered by the bush 13, during the passage through the changing installation through a semicircular bush 14 connected to said central collar which is preferably made of bronze.
  • this configuration of the side chassis of the bearing parts is determined at least in part by the arrangement of the centering and sliding guide rails 19. If these rails had any other arrangement, the configuration of the side chassis would logically be modified such that it carried out the indicated functions.
  • the lock 22 is formed by two vertical rods connected to one another by a hollow bridge designed so that the head of the double T-shaped unlocking guide 24 of the changing track gauge change installation is introduced through said bridge.
  • the lock includes pretensed safety springs 28 to prevent unwanted vertical movements of the lock 22 when it is not in contact with the unlocking guide 24.
  • the fixing device has an additional safety element formed by the bolt 25, connected to the lock 22 and laterally movable, overcoming the force of the spring 21, and a retaining element 26 connected to the tubular element 29.
  • the bolt 25 When the spring 21 is at rest, the bolt 25 is in contact with the retaining element 26 preventing the vertical movement of the lock 22. In order for this movement to be possible it is necessary to apply a force in the spring 21 which laterally moves the bolt 25 and prevents its being retained by the retaining element 26.
  • the changing installation is bidirectional, the change from a larger to smaller gauge track being performed in one direction while the reverse is performed in the opposite direction.
  • the track gauge change process of a wagon reaching the installation from the larger-gauge track is performed as follows.
  • the wheels 1 are on the rails 31 of the larger-gauge track ( Fig. 1A and Fig. 2A ).
  • the fixing device in this phase it is also necessary to act on the horizontal spring 21 in order to laterally move the bolt 25, thereby preventing the retaining element 26 from preventing the lock 22 from dropping.
  • one of the sides of the head of the unlocking guides 24 of the changing installation has a double T-shape with a progressively variable gauge from the ends to the center, smaller at the ends than in the center, as can be seen by comparing Figures 1B and 1C ; therefore the guide 24 serves as an element for actuating the horizontal spring 21 controlling the lateral movement of the bolt 25 ( Fig. 1C and Fig. 2C ).
  • the guides 27 cause the lateral movement of the coupling device for coupling the wheels 1 to the axle 2 until reaching the position corresponding to the smaller-gauge track 32.
  • the downward profile of the guide 24 forces the lock 22 to move up, locking the guide 18 in the new position.
  • the spring 21 remains at rest and the bolt 25 is retained by the retaining element 26 ( Fig. 1D and Fig. 2D ).
