[0048] In the related art, rail vehicles generally have front and rear bogies, both of which are provided with guide wheels, and the cooperation between the guide wheels and the rail beam drives the steering of the running wheels. In some existing technologies, when the rail vehicle is turning, the guide wheels provided on the front and rear bogies are subjected to large forces, the guide wheels are greatly worn, and the curve passing ability of the rail vehicle is poor.

[0049] Reference below Figure 1-Figure 8 A guide structure for a rail vehicle according to an embodiment of the present utility model is described.

[0050] like Figure 1 , Figure 5 As shown, the guide structure according to the utility model includes: a first rotating bracket 30, a second rotating bracket 40 and a linkage 50, the first rotating bracket 30 is provided with a first guide wheel 31 suitable for contacting the track beam; the second rotating bracket 40 is provided with a second guide wheel 41 suitable for contacting the track beam; the linkage 50 is respectively linked with the first rotating bracket 30 and the second rotating bracket 40 so that the first rotating bracket 30 and the second rotating bracket 40 follow each other and rotate in opposite directions. Specifically, the rail vehicle can travel along the extension direction of the track beam, the guide wheel contacts the guide surface of the track beam, and the guide wheel is suitable for driving the running wheel to rotate when the rail vehicle turns, so that the rail vehicle has a tendency to turn.

[0051] Here, the first guide wheel 31 can first contact the guide surface at the curve to drive the first rotating bracket 30 to rotate. At this time, the linkage 50 transmits the rotation trend of the first rotating bracket 30 to the second rotating bracket 40, and drives the second rotating bracket 40 to rotate in the direction opposite to the rotation direction of the first rotating bracket 30, so that the second guide wheel 41 has a turning trend before contacting the guide surface at the curve, so as to reduce the force on the second guide wheel 41 when turning, and at the same time, the second guide wheel 41 rotates to drive the second rotating bracket 40 to rotate, and the linkage 50 can also feed back the rotation trend of the second rotating bracket 40 to the first rotating bracket 30, thereby reducing the force on the first guide wheel 31 when turning.

[0052] Similarly, the second guide wheel 41 may first contact the guide surface at the curve to drive the second rotating bracket 40 to rotate. At this time, the linkage 50 transmits the rotation trend of the second rotating bracket 40 to the first rotating bracket 30, and drives the first rotating bracket 30 to rotate in the direction opposite to the rotation direction of the second rotating bracket 40. The first guide wheel 31 can have a turning trend before contacting the guide surface at the curve to reduce the force on the first guide wheel 31 when turning. At the same time, the first guide wheel 31 rotates to drive the first rotating bracket 30 to rotate. The linkage 50 can also feed back the rotation trend of the first rotating bracket 30 to the second rotating bracket 40, thereby reducing the force on the second guide wheel 41 when turning.

[0053] According to the guide structure of the present invention, a linkage part 50 is provided, so that when the rail vehicle is turning, the first rotating bracket 30 and the second rotating bracket 40 follow each other and rotate in opposite directions, thereby realizing the linkage between the first guide wheel 31 and the second guide wheel 41, reducing the force on a single guide wheel, reducing the degree of wear of a single guide wheel, and improving the turning ability of the rail vehicle.

[0054] In some embodiments, a first axle bridge 10 and a second axle bridge 20 are provided on the rail vehicle, and the first axle bridge 10 and the second axle bridge 20 are generally connected to the body of the rail vehicle. The first axle bridge 10 and the second axle bridge 20 are arranged in the moving direction of the rail vehicle, the first rotating bracket 30 is rotatably provided on the first axle bridge 10, and the second rotating bracket 40 is rotatably provided on the second axle bridge 20.

[0055] According to the guide structure designed in the utility model, the linkage member 50 is arranged on the first rotating bracket 30 and the second rotating bracket 40, so that the linkage member 50 is indirectly connected to the first axle bridge 10 and the second axle bridge 20 through the first rotating bracket 30 and the second rotating bracket 40, which can reduce the vibration transmitted to the body and the running wheels of the rail vehicle and improve the driving experience.

[0056] According to some embodiments of the present invention, Figure 1 , Figure 5 As shown, the first rotating bracket 30 includes a first rotating bracket body and a first driving end 301, and the first driving end 301 is fixedly connected to the first rotating bracket body; the second rotating bracket 40 includes a second rotating bracket body and a second driving end 401, and the second driving end 401 is fixedly connected to the second rotating bracket body. The first driving end 301 is located on one side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40, and the second driving end 401 is located on the other side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40; the two ends of the linkage member 50 are respectively connected to the first driving end 301 and the second driving end 401, so that the first rotating bracket 30 and the second rotating bracket 40 follow each other and rotate in opposite directions.

[0057] Specifically, take the first guide wheel 31 first contacting the guide surface at the bend as an example. Figure 2 , Figure 3As shown, when the first rotating bracket 30 has a tendency to rotate toward the left side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40, the movement amplitude of the first rotating bracket 30 located on the right side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40 is greater than the movement amplitude of the first rotating bracket 30 located on the left side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40. Since the first driving end 301 and the second driving end 401 are located on different sides of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40, the first driving end 301 and the second driving end are connected. The linkage member 50 of 401 transmits the movement trend of the left side of the first rotating bracket 30 to the right side of the second rotating bracket 40, so that the movement amplitude of the part of the second rotating bracket 40 located on the left side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40 is greater than the movement amplitude of the part of the second rotating bracket 40 located on the right side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40. At this time, the first rotating bracket 30 rotates toward the left front, and the linkage member 50 drives the second rotating bracket 40 to rotate toward the right front, so that the second guide wheel 41 has a turning tendency before contacting the guide surface at the curve, so as to reduce the force on the second guide wheel 41 when turning.

[0058] It can be understood that the situation in which the first rotating bracket 30 rotates toward the right side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40 is similar to the situation in which the first rotating bracket 30 rotates toward the left side of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40, and the situation in which the second guide wheel 41 first contacts the guide surface at the curve is also similar to the situation in which the first guide wheel 31 first contacts the guide surface at the curve. Please refer to the above-mentioned embodiment and will not be elaborated here.

[0059] In some embodiments, the rotation axis of the first rotating bracket 30 is parallel to the rotation axis of the second rotating bracket 40 , and at this time, the rotation planes of the first guide wheel 31 and the second guide wheel 41 are parallel.

[0060] In some embodiments, the first guide wheel 31 and the second guide wheel 41 rotate in the same plane.

[0062] In some embodiments, the second connecting rod 52 is parallel to the first connecting rod 51 and is staggered so that the second connecting rod 52 and the first connecting rod 51 are respectively connected to the second driving end 401 and the first driving end 301 located on both sides of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40.

[0063] In some embodiments, the linkage part 53 is respectively linked with the other end of the first link 51 and the other end of the second link 52, which means that the linkage part 53 is respectively movably connected with the other end of the first link 51 and the other end of the second link 52, so as to drive the second link 52 to move under the drive of the first link 51, or drive the first link 51 to move under the drive of the second link 52. According to the guide structure designed by the utility model, the first driving end 301 and the second driving end 401 are connected in the form of multiple links, and the structural rigidity is better, the load bearing capacity is larger, and the durability is higher.

[0075] Compared with the solutions in the aforementioned embodiments, the linkage member 50 in this embodiment is simpler in form and has fewer parts.

[0076] According to some embodiments of the present invention, Figure 5-Figure 8As shown, the first rotating bracket 30 is symmetrically provided with two first driving ends 301 on both sides of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40, and the second rotating bracket 40 is symmetrically provided with two second driving ends 401 on both sides of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40; the connecting rod 54 is constructed as two cross-arranged ones, each connecting rod 54 respectively connects the first driving end 301 and the second driving end 401 located on the opposite sides of the line connecting the rotation axis of the first rotating bracket 30 and the rotation axis of the second rotating bracket 40.
