Technical Field

[0001] At least one embodiment of the present disclosure relates to the technical field of rail vehicle wheels, and more particularly, to a wheel for a rail vehicle and a rail vehicle including the wheel. Background Art

[0002] The track gauge of a rail vehicle refers to the distance between the two wheels on the same axle. Currently, the track gauges of rails on railway lines in different regions are different. When a rail vehicle operates across regions, there may be rails of different track gauges on the railway line. At this time, the rail vehicle needs to adjust the track gauge between the two wheels on the same axle of the rail vehicle according to the actual track gauge of the rails.

[0003] In order to realize automatic adjustment of the track gauge of rail vehicles, in the prior art, a wheelset is usually installed on the wheel so that the axial position of the wheel on the axle can be changed and the wheel can be unlocked and locked, so that the wheel can be accurately moved axially to a predetermined position on the axle after being unlocked, and can be reliably locked after the movement is completed.

[0004] However, the above-mentioned method of installing a wheelset on a wheel to adjust the track gauge of a rail vehicle requires the design of a complex wheelset structure, which affects the reliability of the wheel-axle fit and is not suitable for rail vehicles traveling at high speeds. Summary of the invention

[0010] According to an embodiment of the present disclosure, the connecting portion further includes: a reset mechanism, which is mounted on the spoke plate, the reset mechanism being connected to the connecting mechanism and being configured such that when the rail vehicle passes through the release section, the connecting mechanism disengages from the guide rail, and drives the connecting mechanism to move in a radial direction away from the center of the spoke plate, so that the connecting mechanism is combined with the rim.

[0011] According to an embodiment of the present disclosure, each of the connecting mechanisms includes: a first connecting member, one end of which passes through the spoke plate and the groove body on the linkage mechanism; and a second connecting member, which is detachably coupled to an end of the first connecting member extending out of the linkage mechanism, and the second connecting member is detachably connected to the rim on a side facing the rim.

[0051] According to the inventive concept of one aspect of the present disclosure, a wheel for a rail vehicle is provided, on which a guide rail for changing the track gauge between two wheels facing each other of the rail vehicle is installed; the wheel comprises: a spoke plate installed on the axle of the rail vehicle; a connecting portion, comprising a connecting mechanism, the connecting mechanism being installed on the spoke plate; and a rim being detachably connected to the connecting mechanism, wherein during the travel of the rail vehicle, the connecting mechanism contacts the guide rail and moves toward the center of the spoke plate under the pressure of the guide rail, so that the rim is detached from the connecting mechanism; as the rail vehicle continues to travel, the guide rail pushes the rim to move in an axial direction relative to the spoke plate, and when the connecting mechanism is detached from the guide rail, the connecting mechanism is combined with the rim to adjust the relative position of the rim and the spoke plate in the axial direction.

[0052] Figure 3 is a schematic diagram of assembling a wheel and a guide rail for a rail vehicle according to an embodiment of the present disclosure; Figure 4 is a cross-sectional view of a wheel for a rail vehicle according to an embodiment of the present disclosure; Figure 5 It is a cross-sectional view of the guide rail cross section and a cross-sectional view taken along AA; Figure 6 is a cross-sectional view of the guide rail cross section and a top view along the B direction; Figure 7 yes Figure 4 A partial enlarged view of part P.

[0053] According to an exemplary embodiment of the present disclosure, please refer to Figure 3-Figure 7 , a wheel for a rail vehicle is provided. A guide rail 6 is installed on the rail for changing the track gauge between two wheels facing each other of the rail vehicle. The wheel includes a spoke 1, a connecting portion 2 and a rim 3. The spoke 1 is installed on an axle 7 of the rail vehicle. The connecting portion 2 includes a connecting mechanism 21. The connecting mechanism 21 is installed on the spoke 1. The rim 3 is detachably connected to the connecting mechanism 21. During the running of the rail vehicle, the connecting mechanism 21 contacts the guide rail 6. Under the pressure of the guide rail 6, the rim 3 is connected to the connecting mechanism 21. Figure 7As shown by the arrow X in the middle, the rim 3 moves toward the center of the web 1, so that the rim 3 is separated from the connecting mechanism 21. As the rail vehicle continues to travel, the guide rail 6 pushes the rim 3 to move in the axial direction relative to the web 1, as shown in FIG. Figure 7 As shown by the middle arrow Y, when the connecting mechanism 21 is separated from the guide rail 6, the connecting mechanism 21 is combined with the rim 3 to adjust the relative position of the rim 3 and the web 1 in the axial direction.

[0054] In this embodiment, the rim 3 is detachably connected to the connecting mechanism 21, and under the action of the guide rail 6 installed on the track, during the travel of the rail vehicle, the connecting mechanism 21 contacts the guide rail 6, and moves toward the center of the spoke plate 1 under the pressure of the guide rail 6, so that the rim 3 is detached from the connecting mechanism 21, and as the rail vehicle continues to travel, the guide rail 6 pushes the rim 3 to move in the axial direction relative to the spoke plate 1, and when the connecting mechanism 21 is detached from the guide rail 6, the connecting mechanism 21 is combined with the rim 3 to adjust the relative position of the rim 3 and the spoke plate 1 in the axial direction.

[0055] It should be noted that, in the present embodiment, a support rail 8 for supporting the axle box 71 of the axle 7 is also provided on the track.

[0056] In some exemplary embodiments, referring to Figure 3-Figure 7 A groove 61 extending in the height direction and accommodating the rim 3 is formed on the side of the guide rail 6 facing the spoke 1. The groove 61 includes, in sequence along the longitudinal direction, an extrusion section 611 for extruding the connection mechanism 21, a pushing section 612 for pushing the rim 3 to move in the axial direction relative to the spoke 1, and a releasing section 613 for releasing the connection mechanism 21. When the rail vehicle passes through the extrusion section 611, the connection mechanism 21 is squeezed by the guide rail 6 and moves toward the center of the spoke 1, so that the rim 3 is separated from the connection mechanism 21. When the rail vehicle passes through the pushing section 612, the guide rail 6 pushes the rim 3 to move in the axial direction relative to the spoke 1. When the rail vehicle passes through the releasing section 613, the connection mechanism 21 is separated from the guide rail 6, and the connection mechanism 21 is combined with the rim 3 to lock the relative position of the rim 3 and the spoke 1 in the axial direction.

[0057] Through the above-mentioned arrangement, during the travel of the rail vehicle, it passes through the extrusion section 611, the pushing section 612 and the release section 613 of the guide rail 6 in sequence. When the rail vehicle passes through the extrusion section 611, the connecting mechanism 21 is squeezed by the guide rail 6 and moves toward the center of the spoke 1, so that the rim 3 is separated from the connecting mechanism 21. When the rail vehicle passes through the pushing section 612, the guide rail 6 pushes the rim 3 to move in the axial direction relative to the spoke 1. When the rail vehicle passes through the release section 613, the connecting mechanism 21 is separated from the guide rail 6, and the connecting mechanism 21 is combined with the rim 3 to lock the relative position of the rim 3 and the spoke 1 in the axial direction, thereby achieving the adjustment of the track gauge between the two wheels facing each other of the rail vehicle without stopping the rail vehicle.

[0058] It should be noted that, in this embodiment, the longitudinal direction refers to the traveling direction of the rail vehicle.

[0059] In some exemplary embodiments, referring to Figure 3-Figure 7 The depth of the extrusion section 611 is equal to the depth of the push section 612 and is less than the depth of the release section 613, so that when the rail vehicle passes through the extrusion section 611 and the push section 612, the guide rail 6 squeezes the connection mechanism 21, and when the rail vehicle passes through the release section 613, the guide rail 6 releases the connection mechanism 21. Figure 5 The middle M part shows the structure of the groove 61 of the guide rail 6 that matches the two wheels facing each other during the track gauge adjustment process. Figure 5 Part N in the middle shows the structure of the groove 61 of the matching guide rail 6 after the two wheels facing each other have completed the track gauge adjustment and in the initial period when the track gauge needs to be adjusted again. Figure 5 The N part in the figure can also be removed according to actual needs, and the extrusion section 611 part in the figure can be removed. The extrusion section 611 is arranged in parallel with the release section 613, and the push section 612 is arranged obliquely with the extrusion section 611, such as Figure 6 As shown in the middle part B, when the rail vehicle passes through the pushing section 612, the guide rail 6 pushes the rim 3 to move in the axial direction relative to the web 1.

[0060] In this embodiment, the depth of the extrusion section 611 is equal to the depth of the pushing section 612 and is less than the depth of the release section 613. The extrusion section 611 is arranged in parallel with the release section 613, and the pushing section 612 is arranged inclined with the extrusion section 611 to cooperate in realizing the separation and combination of the connecting mechanism 21 and the rim 3, and the movement of the rim 3 in the axial direction relative to the spoke plate 1.

[0061] Figure 8 It is a schematic plan view of a linkage mechanism for wheels of a rail vehicle according to an embodiment of the present disclosure.

[0062] In some exemplary embodiments, referring to Figure 3-Figure 4 as well as Figure 7-Figure 8 The connecting portion 2 further includes a linkage mechanism 22. The linkage mechanism 22 is configured to be roughly annular, extends in the longitudinal vertical plane, and is rotatably mounted on one side of the spoke plate 1 in the axial direction. A plurality of grooves 221 arranged obliquely relative to the horizontal plane are sequentially arranged in the circumferential direction on the side wall of the linkage mechanism 22 extending in the longitudinal vertical plane. A connecting mechanism 21 is installed inside each groove 221. When the guide rail 6 squeezes one of the connecting mechanisms 21, the squeezed connecting mechanism 21 moves toward the center of the spoke plate 1 inside the groove 221, so that the linkage mechanism 22 rotates relative to the spoke plate 1, so as to drive the remaining connecting mechanisms 21 to move toward the center of the spoke plate 1 and separate from the rim 3.

[0063] Through the above-mentioned arrangement, when the guide rail 6 squeezes one of the connection mechanisms 21, the squeezed connection mechanism 21 moves toward the center of the spoke plate 1 inside the groove body 221, so that the linkage mechanism 22 rotates relative to the spoke plate 1, and thus, under the action of the linkage mechanism 22, the remaining multiple connection mechanisms 21 are driven to move toward the center of the spoke plate 1 and separate from the rim 3. Further, by providing the linkage mechanism 22 and multiple connection mechanisms 21 arranged on the linkage mechanism 22 along the circumferential direction, on the one hand, when the gauge adjustment between the two wheels facing each other of the rail vehicle is completed, the bonding strength between the rim 3 and the spoke plate 1 is improved, and on the other hand, when the gauge adjustment between the two wheels facing each other of the rail vehicle needs to be adjusted, under the action of the linkage mechanism 22, the multiple connection mechanisms 21 are separated from the rim 3 respectively, so as to meet the axial movement of the rim 3 relative to the spoke plate 1.

[0064] In some exemplary embodiments, referring to Figure 3-Figure 7 The connection part 2 further includes a reset mechanism 23. The reset mechanism 23 is mounted on the spoke plate 1 and connected to the connection mechanism 21. The reset mechanism 23 is configured such that when the rail vehicle passes through the release section 613, the connection mechanism 21 is disengaged from the guide rail 6, and the connection mechanism 21 is driven to move away from the center of the spoke plate 1 in the radial direction, so that the connection mechanism 21 is combined with the rim 3.

[0065] In this embodiment, by providing a reset mechanism 23, when the rail vehicle passes through the release section 613, the connecting mechanism 21 disengages from the guide rail 6. Under the action of the reset mechanism 23, the connecting mechanism 21 moves away from the center of the spoke plate 1 in the radial direction, so that the connecting mechanism 21 is combined with the rim 3 to lock the relative position between the rim 3 and the spoke plate 1.

[0066] Fig. 9 is a three-dimensional schematic diagram of a connecting mechanism for a wheel of a rail vehicle according to an embodiment of the present disclosure; Fig.10 Detailed description of the invention is provided in detail.

[0067] In some exemplary embodiments, referring to Figure 3-Figure 4 , Figure 7 as well as Figure 9-10 Each connecting mechanism 21 includes a first connecting member 211 and a second connecting member 212. One end of the first connecting member 211 passes through the web 1 and the slot 221 on the linkage mechanism 22. The second connecting member 212 is detachably coupled to one end of the first connecting member 211 extending out of the linkage mechanism 22, and the side of the second connecting member 212 facing the rim 3 is detachably connected to the rim 3.

[0068] In this embodiment, the connection mechanism 21 is provided with a first connection member 211 and a second connection member 212 that are detachably connected, so as to facilitate the disassembly and assembly between the connection mechanism 21 and the linkage mechanism 22 .

[0069] In some exemplary embodiments, referring to Figure 3-Figure 4 , Figure 7 as well as Figure 9-10 The first connecting member 211 includes a connecting rod 2111 and a first pressing arm 2112. The connecting rod 2111 extends along the axial direction of the spoke 1, and sequentially passes through the spoke 1 and the slot 221 of the linkage mechanism 22. The first pressing arm 2112 is formed at one end of the connecting rod 2111 away from the second connecting member 212, and is suitable for being pressed by the guide rail 6 to drive the connecting rod 2111 to move toward the center of the spoke 1 along the radial direction.

[0070] Through the above arrangement, when the rail vehicle passes through the extrusion section 611 , the guide rail 6 squeezes the first extrusion arm 2112 to drive the connecting rod 2111 to move toward the center of the web 1 along the radial direction.

[0071] In some exemplary embodiments, referring to Figure 3-Figure 4 , Figure 7 as well as Figure 9-10 The first spline 31 is formed on the side of the rim 3 facing the spoke 1. The second connecting member 212 includes a connecting arm 2121 and a second extrusion arm 2123. The connecting arm 2121 extends in a longitudinal vertical plane, and a second spline 2122 matching the first spline 31 is formed on the end of the connecting arm 2121 facing the rim 3. The second extrusion arm 2123 is formed on the side of the connecting arm 2121 away from the first connecting member 211, and is suitable for being extruded by the guide rail 6 to drive the connecting arm 2121 to move toward the center of the spoke 1 along the radial direction.

[0072] Through the above arrangement, when the rail vehicle passes through the extrusion section 611 , the guide rail 6 squeezes the second extrusion arm 2123 to drive the connecting arm 2121 to move toward the center of the web 1 along the radial direction.

[0073] Fig.11It is a schematic plan view of a spoke plate for a wheel of a rail vehicle according to an embodiment of the present disclosure and a partial cross-sectional view taken along an axis.

[0074] In some exemplary embodiments, referring to Figure 3 , Figure 7 as well as Fig.11 A through slot 11 extending in the axial direction is formed on the spoke 1 to allow the connection mechanism 21 to extend. A receiving slot 12 communicating with the through slot 11 is formed inside the spoke 1. The reset mechanism 23 includes a plurality of springs 231, each of which extends in the radial direction, and its two ends are respectively connected to the bottom of the receiving slot 12 and the connection mechanism 21, so that when the connection mechanism 21 is separated from the guide rail 6, under the action of the elastic force of the spring 231, the connection mechanism 21 is driven to move away from the center of the spoke 1 in the radial direction, so that the connection mechanism 21 is combined with the rim 3.

[0075] With the above arrangement, when the rail vehicle passes through the release section 613 , the connection mechanism 21 is separated from the guide rail 6 , and under the action of the elastic force of the spring 231 , the connection mechanism 21 moves away from the center of the spoke 1 in the radial direction, so that the connection mechanism 21 is combined with the rim 3 .

[0076] In some exemplary embodiments, referring to Figure 7 The bottom of the accommodating groove 12 is formed with a plurality of limiting grooves 121 extending in the radial direction at intervals along the axial direction. One end of each spring 231 away from the rim 3 extends into the limiting groove 121 to limit the movement of the spring 231 in a plane perpendicular to the extension direction of the spring 231.

[0077] Through the above arrangement, the spring 231 can only move in the radial direction of the spoke 1, preventing the spring 231 from moving in a plane perpendicular to the extension direction of the spring 231, thereby providing a driving force for the connecting mechanism 21 to move away from the center of the spoke 1 in the radial direction.

[0078] Fig.12 It is a schematic diagram of the assembly of a rim and a spoke plate of a wheel for a rail vehicle according to an embodiment of the present disclosure and a partial cross-sectional view taken along the axis.

[0079] In some exemplary embodiments, referring to Figure 4 , Figure 7 as well as Fig.12 The circumferential outer wall of the spoke plate 1 is connected to the circumferential inner wall of the rim 3 by a trapezoidal thread. The angle of the trapezoidal thread is set so that when the rim 3 is squeezed in the axial direction by the guide rail 6, the rim 3 can move in the axial direction relative to the spoke plate 1, and when the connecting mechanism 21 is separated from the guide rail 6, the relative position of the spoke plate 1 and the rim 3 in the axial direction is limited.

[0080] Through the above arrangement, when the rim 3 is pressed in the axial direction by the guide rail 6, the rim 3 can move in the axial direction relative to the spoke 1 to change the track gauge between the two wheels facing each other of the rail vehicle. When the connecting mechanism 21 is separated from the guide rail 6, the relative position of the spoke 1 and the rim 3 in the axial direction is limited to lock the track gauge between the two wheels facing each other of the rail vehicle.

[0082] According to an exemplary embodiment of the present disclosure, please refer to Figure 1-Figure 2 , a rail vehicle is provided, comprising a vehicle body 4 and the wheel for the rail vehicle described in the above embodiment. The wheel 5 for the rail vehicle is installed at the bottom of the vehicle body 4.

[0083] With the above arrangement, when the rail vehicle is traveling through two sections of track with different track gauges, the guide rail 6 can adjust the track gauge between two wheels 5 facing each other without stopping the rail vehicle.

It should be noted that the implementation methods not shown or described in the drawings or the body of the specification are all forms known to ordinary technicians in the relevant technical field and are not described in detail.
