    [0002] Railway set
    [0003]
    [0004] Object of the invention
    [0005]
    [0006] The present invention relates to a solution for freight wagons that includes a rail set of two or more pairs of wheels of varying width and same torque.
    [0007]
    [0008] More specifically, the present invention relates to a railway assembly for adaptation to different track widths comprising pairs of wheels connected by a fixed axle, where each wheel comprises a system, which by its morphology, allows the rotation of the wheel as its axial displacement once it enters the change in width and where an externally fixed transmission system with axial displacement capacity in its inner part transmits the synchronized torque between axles of each of the wheels of the pair of wheels of the railway assembly.
    [0009]
    [0010] Background of the invention
    [0011]
    [0012] Currently, a wide variety of railway assemblies are known and used to drive on roads of different widths, thus, cars such as those described in ES2353415 have emerged, from this same applicant, which describes a variable-width bogie with a width change device of track and where the pairs of wheels are connected by a rotating and non-fixed axle and that incorporates in its outer areas support pieces of the platform suspension molars on which the pairs of wheels are mounted.
    [0013]
    [0014] ES2151871 describes a self-propelled variable width rolling bogie, where the bogie has at least one fixed axle without rotation in which there are support boxes that allow the movement of the axle only vertically and sliding bushes carrying the wheels with possibility of axial sliding on said axle and where said wheels do not share the same torque.
    [0015]
    [0016] ES2130039 of this same applicant describes a rail axle assembly equipped with automatic track width change and adaptable to conventional merchandise bogies. Said railway axle assembly comprises two independent rolling assemblies that lack a solidarity torque.
    [0017] ES2428239 describes a railway system with automatic width change to multiple track widths. The wheels of this rail system mounted on an axle include several bearings that allow the independent rotation of each of the wheels without a torque of solidarity. Additionally, said railway system allows the transition between railway widths without the need to release the load of the wheels.
    [0018]
    [0019] ES2204483 describes a self-propelled variable-width rolling bogie with pairs of wheels with independent rotation without integral turning torque. Said wheel pairs include bearing systems that distribute the radial load with independent torque for each of the wheels.
    [0020]
    [0021] Thus, one or more disadvantages offered by the bogies or railway assemblies mentioned are a lack of synchronization between pairs of wheels that can cause a poor performance due to the lack of a pair of integral rotation between wheels of the same pair, considerable wear due to lack of robustness due to axial and / or radial loads exerted on the railway assembly and a poor immobilization of the wheels during the change of wheel width for adaptation to a specific track width.
    [0022]
    [0023] For this reason it is necessary a more robust railway assembly that can circulate on tracks of different width, which offers greater resistance to axial and / or radial loads exerted on the railway assembly during its operation, which offers an improved system of immobilization or clamping of the wheels during the change of width compared to the state of the art and that allows synchronization of angular speed between pairs of wheels of the railway assembly.
    [0024]
    [0025] The present invention is related to the satisfaction of this demand.
    [0026]
    [0027] Description of the invention
    [0028]
    [0029] The railway assemblies of adaptation to different track widths of the present invention solve the problems of the prior art, as they include:
    [0030]
    [0031] - Wheel pairs connected by a fixed axle, where said wheels of each pair of wheels define a lateral direction.
    [0032] - For each pair of wheels a first axle connected to a first wheel of the pair of wheels is included. This first axis allows the wheel to rotate on the fixed axis.
    [0033]
    [0034] - For each pair of wheels a second axle connected to a second wheel of the pair of wheels is included. This second axle allows synchronized rotation of the second wheel on the fixed axle.
    [0035]
    [0036] The railway assemblies of the present invention comprise stop or immobilization means executed in combination with axial or lateral load bearings that allow the thrust of the radial load bearings associated with each of the wheels allowing a sliding assembly that changes and seals tightly. the position of each of the wheels of the pair of wheels. These stopping means or immobilization allow a better fixation of the wheels of the wheel pairs during the change of width of wheels thus increasing the robustness of the railway assembly. Axial or lateral thrust bearings and radial load or support bearings are arranged between each of the rotating systems and the fixed shaft.
    [0037]
    [0038] The railway assemblies of the present invention comprise means for changing the wheel width, for the change of track width, which comprises redundant locks for each wheel of the pair of wheels, which allow to vary or fix in a more reliable and safe way in comparison with previous systems the width between wheels of the same pair taking into account the different track widths, such as the Iberian, European or Russian width. Advantageously, the means of changing the wheel width for the change of track can carry out their function with or without wheel unloading.
    [0039]
    [0040] Optionally, the railway assembly systems in some embodiments according to the present invention may include the incorporation of two or more roller skates between pairs of wheels that allow the correct distribution of the loads suffered by the entire railway assembly system during the change wide between pairs of wheels with unloading.
    [0041]
    [0042] Thus, the rail assemblies of the present invention offer greater robustness thanks to said immobilization system in combination with axial load bearings, the use of a fixed axle between pairs of wheels, an advantageous wheel width change system with redundant locks and the incorporation of a transmission system of rotation between wheels of the same pair of wheels by using the transmission system.
    [0043]
    [0044] Description of the drawings
    [0045]
    [0046] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. In an illustrative and non-limiting manner, the following has been represented:

    [0054]
    [0055] Preferred Embodiment of the Invention
    [0056]
    [0057] As can be seen in the aforementioned figures, the fixed axis of variable width object of the present invention is provided to be able to make the change of width of the railway assembly satisfactorily and increasing its robustness compared to inventions of the prior art. Thus, Figure 1 shows the first rail set of adaptation to different track widths in accordance with a preferred embodiment of the present invention and offering the said advantages. Said set is formed by pairs of wheels (2). Each pair of wheels (2) comprises a fixed axle (1) that connects the pair of wheels (2) which define a lateral direction (3). Each of the wheels of the pair of wheels comprises an axle connected to said wheel and which allows the wheel to rotate on the fixed axle (1). In addition, a synchronized turn transmission system (16) can be seen. Said transmission system (16) allows the transmission of the torque between the first axis and the second axis The transmission system (16) allows the pair of wheels (2) to rotate in solidarity.
    [0058]
    [0059] Figure 1 also shows a pair of support skates (4) for each wheel and located in the cover (17) of the grease box (15) together with the supports of the fixed axle (1) and that allow the correct distribution of the loads suffered by the railway assembly and where each of the support skates (4) is adapted to rest on a platform of change of width called changer (5) leaving free of charge the pair of wheels (2) and their axes in the lateral direction (3). These skates, with the system of change of width without unloading of pairs of wheels (2) would not be necessary, therefore they are an option to consider.
    [0060]
    [0061] Figure 2 shows another railway assembly adapting to different track widths in accordance with another embodiment of the present invention. In this railway assembly, the torque transmission system, that is, the transmission system (16) allows axial displacement to one of the axes and integral to the opposite axis while being connected to the wheel of said opposite axis. As in Figure 1, Figure 2 also shows the pairs of support skates (4) located in the cover (17) of the grease box (15) and adapted to rest on a platform for changing width called changer (5) leaving the pair of wheels (2) and their axles free of charge in the lateral direction (3).
    [0062]
    [0063] Both the railway assembly of Figure 1 and that of Figure 2 include stop means (6) and (7) that allow the immobilization of the pair of wheels (2), according to the lateral direction (3) and width change means between wheels of each of the pairs (2), according to the lateral direction (3).
    [0064]
    [0065] Figure 3 shows the wheel width change means for all railway assemblies of the present invention. Said width change means comprise two double bolts (9) with redundant function for each of the two wheels of the pair of wheels (2), where each of the two bolts (9) obtains a rest position operated by a spring internal (14), and where the width change means are in said fat box (15).
    [0066]
    [0067] Figure 4 shows a sectional view of the first railway system associated with the assembly of Figure 1 according to an embodiment of the present invention, where first stop means (6) and (7) can be seen that ensure the blockage of the width change system located inside the grease box. This document describes first stop means for the rail assemblies of Figure 1 and 2 and second stop means used in combination with the rail set of Figure 2 and shown in Figure 6, thus obtaining three alternative rail systems that They offer the advantages previously described.
    [0068]
    [0069] Figure 4 shows the first stop means (6) and (7) that ensure the locking of the pair of wheels (2) of the railway assembly of Figure 1 according to the lateral direction (3). The first stop means (6) and (7) comprise for each of the wheels of the pair of wheels (2) an external stop (6) mounted on a sword (8) housed in the grease box (15) and located at the end of said sword (8) distant from the center of the fixed axis (1) and adapted to stop on each of the bolts (9) previously shown in Figure 3.
    [0070]
    [0071] Additionally, the first stop means (6) and (7) comprise an inner stop (7) mounted on the sword (8) and also housed in the grease box (15) and located at the inner end of said sword (8) ) close to the center of the fixed shaft (1) and adapted to fix an axial or lateral thrust bearing (10) and (19). Said stop means (6) and (7) are guided by mechanized flat faces on the fixed axis (1) and define an anti-rotation system on the axis of the lateral direction (3).
    [0072]
    [0073] The axial or lateral thrust bearing (10) and (19) for the absorption of axial loads and radial load bearing or support (11) for the absorption of radial loads are arranged between the rotating axis of each of the wheels and fixed axle (1). The axial or lateral thrust bearing (10) and (19) axially displaces the radial load bearing or support (11) on a sliding track (13) fixed on the fixed axis (1) (or internal ring of said bearing of radial load or support (11)) allowing a sliding assembly (12) that changes and fixes the position of the wheel tightly.
    [0074]
    [0075] Figure 5 shows a sectional view of the second rail system associated with the second rail set of Figure 2 in combination with the first stop means according to an embodiment of the present invention. In Figure 5, the torque transmission system (16) allows axial displacement to one of the axes and integral to the opposite axis while being connected to the wheel of said opposite axis. The first stop means (6) and (7) that ensure the blocking of the pair of wheels (2) can also be seen as in Figure 4. Similar to the first system of Figure 4, the axial or lateral thrust bearing (10) and (19) for the absorption of axial loads and radial load bearing or support (11) for the absorption of radial loads are they have between the rotating axle of each of the wheels and the fixed axle (1). The axial or lateral thrust bearing (10) and (19) axially displaces the radial load bearing or support (11) on a sliding track (13) fixed on the fixed axis (1) (or internal ring of said bearing of radial load or support (11)) allowing a sliding assembly (12) that changes and fixes the position of the wheel tightly.
    [0076]
    [0077] Figure 6 shows a sectional view of the third rail system associated with the rail assembly of Figure 2 and in combination with the second stop means, thus obtaining the third rail system according to an embodiment of the present invention.
    [0078]
    [0079] The second stop means ensure the locking of the pair of wheels (2), according to the lateral direction (3) they comprise a hub (20) fixed on the outside of the fixed axle (1) and housed in the grease box (15) . The hub (20) functions as a stop between the two bolts (9) and one or more ball joints (21) or bushings (22). The hub (20) also functions as a lateral thrust system towards the axial or lateral thrust bearing (10) and (19) through tensioning shafts (23) that act as fixation between the hub (20) and the bearing of axial or lateral thrust (10) and (19).
    [0080]
    [0081] The tensioning shafts (23) act as an anti-rotation system for axial or lateral thrust bearing (10) and (19), since in this railway assembly, the fixed shaft (1) does not have any type of emptying or machining as It can be seen in Figure 6, that is, this fixed axis (1) does not comprise a sword (8) in contrast to the systems of Figures 4 and 5 allowing this railway system to be even more robust and reliable than the systems previously described.
    [0082]
    [0083] Thus, the tensioning shafts (23) fix the axial or lateral thrust bearing (10) and (19) thus achieving the correct position of the pair of wheels (2) absorbing the lateral loads that are caused by the thrust of the pair of wheels in the lateral direction (3) and increasing the robot and reducing the wear of the system.
    [0084]
    [0085] Similar to the first stop means (6) and (7), in the second stop means the axial or lateral thrust bearing (10) and (19) for the absorption of axial loads and radial load bearing or support bearings (11) for the absorption of radial loads, they are arranged between the rotating axle of each of the wheels and the fixed axle (1). The axial or lateral thrust bearing (10) and (19) axially displaces the radial load bearing or support (11) on a sliding track (13) fixed on the fixed axis (1) (or internal ring of said load bearing or radial support (11)) allowing a sliding assembly (12) that changes and fixes the position of the wheel tightly.
    [0086]
    [0087] In the cover (17) of the grease box 15, there are the pairs of support skates (4) and the supports of the bushings (22) or ball joints (21) that allows us to correctly distribute the loads that suffer all the system. These skates of support (4) with the system of change of width without unloading of wheels (2), would be optional.
