[0056] The guide system of the rail vehicle generally adopts hard guide mode, that is, a special guide cantilever and guide wheel are arranged below the rail vehicle, and the guide cantilever is connected with the steering part and the running wheel of the rail vehicle. When the guide wheel contacts the guide surface of the rail beam and deflects, the running wheel is deflected to make the rail vehicle turn. However, due to the limitation of construction method and construction precision, the spacing and flatness error between the guide surfaces on both sides of the rail beam are large, and the guide wheel is easily subjected to a large amount of irregular lateral excitation in the driving process, and the running wheel swings frequently, resulting in poor stability of the rail vehicle in the driving process. In order to solve this problem, the embodiment of the present application provides a guide device 10, a bogie 100, a rail vehicle 1000 and a rail transit system 10000( Figure 1 As shown in the figure).

[0057] Please refer to Figures 1 to 3The guiding device 10 of this application embodiment includes a steering component 11 and a first guiding assembly 13. The steering component 11 is connected to the running wheels 700 of the rail vehicle 1000. The first guiding assembly 13 is connected to the steering component 11 and is used to control the working state of the steering component 11 according to a control signal, so as to control the traveling direction of the running wheels 700 through the steering component 11.

[0058] Specifically, the guiding device 10 of this application is applied to a rail vehicle 1000. The guiding device 10 guides the running wheels 700 of the rail vehicle 1000 when it is in motion, ensuring that the rail vehicle 1000 travels accurately along the track beam 3000 and preventing derailment. The rail vehicle 1000 refers to a vehicle that travels on a specific track beam 3000. The rail vehicle 1000 includes, but is not limited to, trains, high-speed trains, subways, and light rail. The track beam 3000 includes, but is not limited to, dedicated track beams for railways, subways, and light rail. The rail vehicle 1000 of this application can be used for airport shuttles, scenic area sightseeing, and community-based circular transportation. The rail vehicle 1000 includes running wheels 700 that cooperate with the track beam 3000 to enable the rail vehicle 1000 to travel on the track beam 3000. The guide device 10 of this application is connected to the running wheel 700. The guide device 10 is used to guide the running wheel 700 so that the running wheel 700 can travel along the track beam 3000.

[0059] Please see Figure 2 and Figure 3 The first guide assembly 13 is communicatively connected to an external control device. When the control device sends a control signal to the first guide assembly 13, the first guide assembly 13 can drive the traveling wheel 700 to move straight or turn via the steering component 11. This applies when the rail vehicle 1000 is traveling on a straight section of the track beam 3000 (…). Figure 2 As shown), the first guide component 13 can receive a first control signal input from the control device. At this time, the first guide component 13 can control the steering component 11 to be in a first state. When the steering component 11 is in the first state, the steering component 11 does not rotate relative to the track beam 3000, so the steering component 11 drives the running wheel 700 to not turn. That is, the steering component 11 drives the running wheel 700 to remain in a non-turning position, so the rail vehicle 1000 can maintain straight travel along the straight section of the track beam 3000, and the rail vehicle 1000 has good stability. When the rail vehicle 1000 is traveling at a bend or fork in the track beam 3000 ( Figure 3When the steering member 11 is in the second state, the steering member 11 is steered relative to the track beam 3000, so that the steering member 11 can steer the bogie wheel 700, so as to enable the track vehicle 1000 to smoothly pass through the turning or the forked intersection of the track beam 3000.

[0060] The first guide assembly 13 and the steering member 11 can actively adjust the running direction of the bogie wheel 700, and the running direction of the bogie wheel 700 does not need to be completely achieved by the cooperation of the guide member and the track beam 3000, and the construction precision requirement of the track beam 3000 can be lower. The better the smoothness of the control signal input to the first guide assembly 13, the softer the steering of the track vehicle 1000, and the better the stability of the track vehicle 1000.

[0061] In the guide device 10 of the embodiment, after the first guide assembly 13 receives the control signal, the first guide assembly 13 can control the working state of the steering member 11, so that the steering member 11 can control the running direction of the bogie wheel 700. Compared with the current guide device 10, the first guide assembly 13 and the steering member 11 of the present application can actively adjust the running direction of the bogie wheel 700, the running of the track vehicle 1000 is less affected by the precision of the track beam 3000, and the stability of the track vehicle 1000 is better.

[0062] The guide device 10 will be further described below in combination with the accompanying drawings.

[0063] Please refer to Figure 2 and Figure 3 In some embodiments, the first guide assembly 13 includes an actuator 131, a pull rod component 133, and a linkage member 135, one end of the pull rod component 133 is fixedly connected with the actuator 131, the other end of the pull rod component 133 is rotatably connected with one end of the linkage member 135, the other end of the linkage member 135 is fixedly connected with the steering member 11, and the actuator 131 is used to output driving force to the pull rod component 133 according to the control signal.

[0064] The actuator 131 is used for communication with an external control device. After receiving a control signal from the control device, the actuator 131 can drive the tie rod component 133 to remain stationary or move relative to the track beam 3000. The tie rod component 133 is used to transmit the driving force of the actuator 131 to the linkage component 135. Since the tie rod component 133 and the linkage component 135 are connected in a driveable manner, the movement of the tie rod component 133 can drive the linkage component 135 to rotate. The linkage component 135 is used to transmit the driving force of the tie rod component 133 to the steering component 11. When the linkage component 135 rotates, it can drive the steering component 11 to rotate. Preferably, the steering component 11 can rotate along the main shaft of the rail vehicle 1000, thereby driving the running wheels 700 to rotate.

[0065] When the rail vehicle 1000 travels on the straight section of the track beam 3000 ( Figure 2 As shown, upon receiving a control signal, actuator 131 controls the tie rod assembly 133 to remain stationary relative to the track beam 3000; that is, the tie rod assembly 133 does not move at this time. With the tie rod assembly 133 stationary relative to the track beam 3000, the linkage 135 and steering assembly 11 also remain stationary relative to the track beam 3000. The bogie 100 does not rotate relative to the track beam 3000, thus the running wheels 700 do not rotate, and the rail vehicle 1000 can maintain straight travel along the straight section of the track beam 3000.

[0066] When rail vehicle 1000 is traveling at a bend or fork in the track beam 3000 ( Figure 3 As shown, when the actuator 131 receives a control signal, it drives the pull rod component 133 to move, and the pull rod component 133 can drive the linkage component 135 to rotate. Since the linkage component 135 is fixedly connected to the steering component 11, when the linkage component 135 rotates, the steering component 11 can rotate synchronously with the linkage component 135, so that the steering component 11 can drive the running wheel 700 to turn, and the rail vehicle 1000 can smoothly pass through the turning point or fork in the track beam 3000.

[0067] Please see Figure 2 and Figure 3 In some embodiments, the first guide assembly 13 further includes a mounting member 137, on which the actuator 131 is mounted, so that the actuator 131 can be fixed relative to the track beam 3000, and the driving force output by the actuator 131 to the pull rod component 133 is relatively stable.

[0068] Please see Figure 2 and Figure 3 In some embodiments, the lever component 133 includes a first lever 1331 and a second lever 1333. One end of the first lever 1331 is fixedly connected to the actuator 131, and one end of the second lever 1333 is rotatably connected to the linkage 135.

[0069] When rail vehicle 1000 is traveling at a bend or fork in the track beam 3000 ( Figure 3 As shown), after receiving the control signal from the control device, the actuator 131 outputs driving force to the first pull rod 1331. The first pull rod 1331 transmits the driving force to the second pull rod 1333. The second pull rod 1333 can drive the linkage 135 to rotate, thereby the linkage 135 can drive the steering component 11 to rotate, and the steering component 11 can drive the running wheel 700 to rotate.

[0070] Please see Figure 2 and Figure 3 In some embodiments, the tie rod assembly 133 includes only a first tie rod 1331 and a second tie rod 1333, which are rotatably connected. When the rail vehicle 1000 is traveling at a bend or fork in the track beam 3000, the actuator 131 can drive the first tie rod 1331 to move along the width direction X of the track beam 3000, the first tie rod 1331 can drive the second tie rod 1333 to move, and the second tie rod 1333 can drive the linkage 135 to rotate, thereby the linkage 135 can drive the steering component 11 to turn.

[0071] Preferably, one end of the second pull rod 1333 is hinged to the linkage 135, and the other end of the second pull rod 1333 is hinged to the other end of the first pull rod 1331, thereby enabling a rotatable connection between the first pull rod 1331 and the second pull rod 1333, and also enabling a rotatable connection between the second pull rod 1333 and the linkage 135. In one example, both ends of the second pull rod 1333 are spherical structures, thus enabling a hinged (rotatable) connection between the second pull rod 1333 and the linkage 135, and also enabling a hinged (rotatable) connection between the second pull rod 1333 and the first pull rod 1331. In another example, the other end of the first pull rod 1331 is a spherical structure, and the end of the linkage 135 connected to the second pull rod 1333 is a spherical structure, thus enabling a hinged (rotatable) connection between the second pull rod 1333 and the linkage 135, and also enabling a hinged (rotatable) connection between the second pull rod 1333 and the first pull rod 1331. Other possible implementation methods will not be listed here. In this application, both ends of the second pull rod 1333 are spherical structures. In this case, it is only necessary to process the spherical structures on the second pull rod 1333, and the processing of the first guide component 13 is relatively simple.

[0072] Please see Figure 2 and Figure 3In other embodiments, the pull rod assembly 133 further includes at least one third pull rod hinged between the first pull rod 1331 and the second pull rod 1333. The number of third pull rods may be, but is not limited to, one, two, three, four, or more. The pull rod assembly 133 may also include a fourth pull rod and a fifth pull rod, etc., hinged between the first pull rod 1331 and the second pull rod 1333. Exemplarily, in the case where the pull rod assembly 133 also includes a third pull rod hinged between the first pull rod 1331 and the second pull rod 1333, one end of the first pull rod 1331 is fixedly connected to the actuator 131, the second end of the first pull rod 1331 is hinged (rotatably connected) to one end of the third pull rod, the other end of the third pull rod is hinged to one end of the second pull rod 1333, the other end of the second pull rod 1333 is hinged to one end of the linkage 135, and the other end of the linkage 135 is fixedly connected to the steering member 11.

[0073] When rail vehicle 1000 is traveling at a bend or fork in the track beam 3000 ( Figure 3 As shown), actuator 131 can drive first tie rod 1331 to move along the width direction X of track beam 3000. First tie rod 1331 can drive third tie rod to move. Third tie rod movement can drive second tie rod 1333 to move. Second tie rod 1333 can drive linkage 135 to rotate, so linkage 135 can drive steering component 11 to turn.

[0074] Please see Figure 2 and Figure 3 In some embodiments, the steering component 11 includes two components, the first guide assembly 13 includes two tie rod components 133 and two linkage components 135, and each of the opposite sides of the actuator 131 is provided with a tie rod component 133 and a linkage component 135, and the two steering components 11 are respectively connected to the two linkage components 135.

[0075] When the rail vehicle 1000 is traveling at a curve or fork in the track beam 3000, the actuator 131, upon receiving a control signal, drives the two tie rod components 133 on both sides to move simultaneously. One tie rod component 133 drives a linkage 135 to rotate, which in turn drives a steering component 11 to turn, thereby turning a running wheel 700. The other tie rod component 133 drives another linkage 135 to rotate, which in turn drives another steering component 11 to turn, thereby turning another running wheel 700. Thus, the rail vehicle 1000 can achieve active steering.

[0076] Please see Figures 1 to 3Further, in some embodiments, the guiding device 10 further comprises a second guiding assembly 15, the second guiding assembly 15 is connected with the turning piece 11, and in the case that the track vehicle 1000 travels to the turning place or the forked intersection of the track beam 3000, the second guiding assembly 15 cooperates with the track beam 3000 to guide the running wheel 700 through the turning piece 11.

[0077] In the case that the track vehicle 1000 travels to the turning place or the forked intersection of the track beam 3000, when the first guiding assembly 13 controls the travel direction of the running wheel 700 through the turning piece 11, the second guiding assembly 15 is used to assist in guiding the running wheel 700 through the turning piece 11, so that the track vehicle 1000 can travel along the track beam 3000 accurately, and the travel of the track vehicle 1000 is more stable. Moreover, in the case that the first guiding assembly 13 controls the turning of the running wheel 700, if the control of the first guiding assembly 13 on the running wheel deviates or the first guiding assembly 13 fails, the second guiding assembly 15 can keep cooperating with the track beam 3000, the second guiding assembly 15 can drive the turning piece 11 to turn, so that the turning piece 11 can drive the running wheel 700 to turn, and the setting of the second guiding assembly 15 can ensure that the track vehicle 1000 can travel along the track beam 3000 at the turning place or the forked intersection, and the stability of the travel of the track vehicle 1000 is better.

[0078] Please refer to Figures 1 to 3 In some embodiments, the second guiding assembly 15 comprises a connecting piece 151 and a guiding wheel 153, one end of the connecting piece 151 is connected with the turning piece 11, and the other end of the connecting piece 151 is connected with the guiding wheel 153, and the guiding wheel 153 is used to cooperate with the track beam 3000 and transmit the guiding force to the turning piece 11 through the connecting piece 151.

[0079] The connecting piece 151 is used to connect the turning piece 11 and the guiding wheel 153, and the connecting piece 151 is fixedly connected with the turning piece 11 and the guiding wheel 153. In the case that the guiding wheel 153 cooperates with the track beam 3000, the connecting piece 151 can transmit the guiding force of the guiding wheel 153 to the turning piece 11. In the case that the track vehicle 1000 travels to the turning place or the forked intersection of the track beam 3000, the guiding wheel 153 cooperates with the track beam 3000, and the connecting piece 151 transmits the guiding force of the guiding wheel 153 to the turning piece 11, so that the connecting piece 151 can drive the turning piece 11 to turn, and the turning piece 11 can drive the running wheel 700 to turn.

[0080] The extension direction of the central axis of the guide wheel 153 is different from the extension direction of the central axis of the running wheel 700, and the extension direction of the central axis of the guide wheel 153 of the present application is perpendicular to the extension direction of the central axis of the running wheel 700. When the rail vehicle 1000 is running, the surface of the guide wheel 153 cooperates with the rail beam 3000, so that the guide wheel 153 can guide the running wheel 700.

[0081] The material of the connecting piece 151 includes but is not limited to metal or plastic, etc. In the case of metal material of the connecting piece 151, the structural strength of the connecting piece 151 is higher, and the connecting piece 151 can stably transmit the guiding force of the guide wheel 153 to the steering piece 11, so that the steering piece 11 drives the running wheel 700 to turn, and the running of the rail vehicle 1000 is more stable, which can avoid the problem of shaking of the rail vehicle 1000 when running. In the case of plastic material of the connecting piece 151, the cost of the connecting piece 151 is lower, and the weight is lighter.

[0082] The connecting piece 151 and the steering piece 11 can be detachably or non-detachably connected, preferably, the connecting piece 151 and the steering piece 11 are detachably connected, thereby facilitating the maintenance and replacement of the second guide assembly 15. The connecting piece 151 and the guide wheel 153 can also be detachably connected, thereby facilitating the replacement of the guide wheel 153 in the case of excessive wear or damage of the guide wheel 153. The detachable connection mode can be but not limited to threaded connection, screw connection or clamping connection, etc.

[0083] Please refer to Figure 2 and Figure 3 In some embodiments, the connecting piece 151 includes a first connecting part 1511 and a second connecting part 1513, one end of the first connecting part 1511 is connected with the steering piece 11, the other end of the first connecting part 1511 is connected with one end of the second connecting part 1513, the other end of the second connecting part 1513 is connected with the guide wheel 153, the extension direction of the first connecting part 1511 is consistent with the running direction of the rail vehicle 1000, the extension direction of the second connecting part 1513 is consistent with the width direction X of the rail beam 3000, the first connecting part 1511 and the second connecting part 1513 jointly form an avoiding space 1515, and the running wheel 700 is located in the avoiding space 1515.

[0084] The first connecting part 1511 and the second connecting part 1513 can be an integral structure or a split structure. In the case of an integral structure, the first connecting part 1511 and the second connecting part 1513 can be integrally formed, and the processing steps of the connecting piece 151 are relatively simple. In the case of a split structure, the first connecting part 1511 and the second connecting part 1513 can be detachably or non-detachably connected. The avoidance space 1515 is used for the running wheel 700 to be located therein. The first connecting part 1511 and the second connecting part 1513 are approximately 90° included angle, at this time, the structure of the connecting piece 151 is relatively stable, and the structural strength is relatively high. The first connecting part 1511 and the second connecting part 1513 can stably transmit the guiding force of the guide wheel 153 to the steering piece 11, so that the steering piece 11 drives the running wheel 700 to steer, and the running of the rail vehicle 1000 is relatively stable. In addition, the overall volume of the guiding device 10 is also relatively small, which is beneficial to the miniaturization design of the guiding device 10.

[0085] Please refer to Figures 1 to 3 In some embodiments, the second guiding assembly 15 includes two, and the two second guiding assemblies 15 are respectively connected with the two steering pieces 11.

[0086] Among them, one second guiding assembly 15 can include one connecting piece 151 and at least one guide wheel 153. Exemplarily, the number of guide wheels 153 that can be included in one second guiding assembly 15 is one, two, three or more. One second guiding assembly 15 of the present application includes one guide wheel 153, at this time, the structure of the second guiding assembly 15 is relatively simple, and the assembly of the second guiding assembly 15 is relatively simple. In the case of two second guiding assemblies 15, one connecting piece 151 connects one steering piece 11 and one guide wheel 153, and the other connecting piece 151 connects the other steering piece 11 and the other guide wheel 153. The two second guiding assemblies 15 are respectively located on the two sides of the actuator 131.

[0087] In the case of the rail vehicle 1000 running to the straight place of the track beam 3000 Figure 2 As shown, the two guide wheels 153 are spaced apart from the track beam 3000, that is, in the case of the rail vehicle 1000 running to the straight place of the track beam 3000, the second guiding assembly 15 does not play a guiding role to the running wheel 700, at this time, only the first guiding assembly 13 plays a guiding role to the running wheel 700, the first guiding assembly 13 can actively control the running direction of the running wheel 700, and the running stability of the rail vehicle 1000 is better. In the case of the rail vehicle 1000 running to the turning place or the forked intersection of the track beam 3000 Figure 3As shown in FIG. 1, when the track vehicle 1000 is running along the track beam 3000, the track vehicle 1000 is far away from the outer side of the track beam 3000 (the side far away from the center of the turn of the track beam 3000), and thus the guide wheel 153 of the second guide assembly 15 far away from the outer side of the track beam 3000 is separated from the track beam 3000. In this case, the connection member 151 connected with the guide wheel 153 does not transmit the guide force to the steering member 11, and thus the steering member 11 does not steer the running wheel 700, and the track vehicle 1000 can run along the track beam 3000.

[0088] As shown in FIG. 1, the track vehicle 1000 includes a running wheel 700, a steering member 11, a guide device 10, and a driving device 20. Figure 2 Figure 3 In some embodiments, the track width of the two guide wheels 153 is greater than the track width of the two running wheels 700 in the width direction X of the track beam 3000. In this case, when the track vehicle 1000 runs to the turn or the fork of the track beam 3000, one of the guide wheels 153 can be matched with the outer side of the track beam 3000, so that the connection member 151 connected with the guide wheel 153 can transmit the guide force to the steering member 11, and the steering member 11 can steer the running wheel 700 connected with the steering member 11, so that the track vehicle 1000 can run along the track beam 3000. At the same time, when the guide wheel 153 is matched with the track beam 3000, the side of the running wheel 700 can be spaced apart from the track beam 3000, so that the friction between the side of the running wheel 700 and the track beam 3000 can be avoided during the running of the track vehicle 1000, the service life of the running wheel 700 is longer, and the running of the track vehicle 1000 is smoother.

[0089] As shown in FIG. 1, the track vehicle 1000 includes a running wheel 700, a steering member 11, a guide device 10, and a driving device 20. Figure 2 Figure 3 In some embodiments, the second guide assembly 15 is located on the opposite side of the steering member 11 from the first guide assembly 13. In this case, the interference between the first guide assembly 13 and the second guide assembly 15 can be avoided. The first guide assembly 13 and the second guide assembly 15 do not need to consider the problem of mutual avoidance in design, and the structures of the first guide assembly 13 and the second guide assembly 15 are relatively simple. In other embodiments, the second guide assembly 15 is located on the same side of the steering member 11 as the first guide assembly 13. In this case, the structure of the guide device 10 is relatively compact, the overall size of the guide device 10 can be smaller, and the miniaturization design of the guide device 10 is facilitated.

[0090] As shown in FIG. 1, the track vehicle 1000 includes a running wheel 700, a steering member 11, a guide device 10, and a driving device 20. Figure 1 In some embodiments, the bogie 100 includes the guide device 10 of the above-mentioned embodiments.

Compared with the current guide device 10, the first guide assembly 13 of the present application cooperates with the steering part 11, which can actively adjust the running direction of the running wheel 700, and the running of the track vehicle 1000 is less affected by the precision of the track beam 3000, and the running stability of the track vehicle 1000 is better.

[0092] Please refer to Figures 1 to 4 Further, in some embodiments, the bogie 100 further comprises an axle 30, the steering part 11 is connected with the end of the axle 30, and the mounting part 137 is connected between the opposite ends of the axle 30.

[0093] In the width direction X of the track beam 3000, the axle 30 is used to connect two running wheels 700, so that the operation of the two running wheels 700 is more synchronized. The axle 30 is also connected with the car body of the track vehicle 1000, and the axle 30 is installed below the car body. The weight of the car body is transmitted to the running wheel 700 through the axle 30, and is applied to the track beam 3000 through the running wheel 700.

[0094] The steering part 11 of the present application is two, and in the width direction X of the track beam 3000, the two steering parts 11 are respectively located at the two ends of the axle 30. The axle 30 is provided with a bearing, and the two steering parts 11 are connected with the bearing on the axle 30, so that the steering part 11 can rotate relative to the axle 30 with the central axis of the bearing as the center.

[0095] The mounting part 137 is detachably mounted on the axle 30, wherein the detachable mounting mode can be but is not limited to threaded connection, screw connection or buckle connection, etc. The mounting part 137 of the present application is screw connected with the axle 30, and the mounting part 137 and the axle 30 are fastened by screws, so that the connection between the mounting part 137 and the axle 30 is more stable. In the case that the actuator 131 is installed on the mounting part 137, the actuator 131 can be fixed relative to the axle 30, and the actuator 131 is not easy to fall off, and the driving force transmitted to the pull rod part 133 by the actuator 131 is more stable, so that the first guide assembly 13 can better control the running direction of the running wheel 700.

[0096] Please refer to Figure 2 and Figure 3In some embodiments, the first guide assembly 13 and the second guide assembly 15 are respectively located on two sides of the axle 30 in the running direction of the rail vehicle 1000. In one example, the first guide assembly 13 is located in front of the axle 30 and the second guide assembly 15 is located behind the axle 30 in the running direction of the rail vehicle 1000. In another example, the first guide assembly 13 is located behind the axle 30 and the second guide assembly 15 is located in front of the axle 30 in the running direction of the rail vehicle 1000. In this case, the problem of interference between the first guide assembly 13 and the second guide assembly 15 can be avoided. The first guide assembly 13 and the second guide assembly 15 do not need to consider the problem of mutual avoidance in design, and the structure of the first guide assembly 13 and the second guide assembly 15 is relatively simple. In other embodiments, the first guide assembly 13 and the second guide assembly 15 are located on the same side of the axle 30 in the running direction of the rail vehicle 1000. The first guide assembly 13 and the second guide assembly 15 can be located in front of the axle 30 or behind the axle 30 in the running direction of the rail vehicle 1000. In this case, the structure of the guide device 10 is relatively compact, the overall size of the guide device 10 can be smaller, and the miniaturization design of the guide device 10 is facilitated.

[0097] Referring to Figure 2 and Figure 3 In some embodiments, the second guide assembly 15 is located on one side of the axle 30 in the running direction of the rail vehicle 1000. The second guide assembly 15 can be located in front of the axle 30 or behind the axle 30 in the running direction of the rail vehicle 1000. In this case, the structure of the guide device 10 is relatively simple, the installation of the guide device 10 is relatively simple, and in the case that the rail vehicle 1000 runs to the turning place or the forked place of the rail beam 3000, the second guide assembly 15 can effectively guide the running wheel 700 through the turning piece 11. In other embodiments, the second guide assembly 15 is located on both sides of the axle 30 in the running direction of the rail vehicle 1000. In this case, in the case that the rail vehicle 1000 runs to the turning place or the forked place of the rail beam 3000, the second guide assembly 15 can guide the running wheel 700 through the turning piece 11 better. The second guide assembly 15 can accurately turn the running wheel 700 through the turning piece 11, the error of the running wheel 700 is small, so that the rail vehicle 1000 can accurately run along the rail beam 3000, and the problem of derailment of the rail vehicle 1000 can be further avoided.

[0098] Referring to Figure 1The rail vehicle 1000 of the embodiments of the present application comprises the bogie 100 and the car body of the above-mentioned embodiments, and the car body is connected with the bogie 100. The bogie 100 is installed below the car body, and the bogie 100 can control the running direction of the running wheel 700, so that the running wheel 700 can drive the car body to run along the track beam 3000.

[0099] In the rail vehicle 1000 of the embodiments of the present application, after the first guide assembly 13 receives the control signal, the first guide assembly 13 can control the working state of the steering piece 11, so that the steering piece 11 can control the running direction of the running wheel 700. Compared with the current guide device 10, the first guide assembly 13 of the present application cooperates with the steering piece 11 to actively adjust the running direction of the running wheel 700, so that the running of the rail vehicle 1000 is less affected by the precision of the track beam 3000, and the stability of the running of the rail vehicle 1000 is better.

[0100] Please refer to Figures 1 to 3 In some embodiments, the rail vehicle 1000 further comprises at least two running wheels 700, and the at least two running wheels 700 are respectively connected with the two steering pieces 11. One steering piece 11 is connected with one running wheel 700, and one steering piece 11 is used to drive one running wheel 700 to steer. Another steering piece 11 is connected with another running wheel 700, and another steering piece 11 is used to drive another running wheel 700 to steer. In the case that the first guide assembly 13 and the second guide assembly 15 need to control the running direction of the running wheel 700, the steering piece 11 connected with the running wheel 700 can effectively drive the running wheel 700 to steer, so that the rail vehicle 1000 can run along the track beam 3000.

[0101] Please refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the rail vehicle 1000 further comprises a rollover prevention piece 500, and the rollover prevention piece 500 is installed on the car body. The rollover prevention piece 500 cooperates with the track beam 3000 and is used to limit the rollover of the car body relative to the track beam 3000. The rollover prevention piece 500 is installed on the bottom of the car body. During the running of the running wheel 700 along the track beam 3000, the rollover prevention piece 500 cooperates with the track beam 3000, so that the safety of the rail vehicle 1000 during running can be improved, and the problem of rollover of the rail vehicle 1000 can be avoided.

[0102] Please refer to Figure 1 , Figure 4 and Figure 5 Specifically, in some embodiments, the rollover prevention piece 500 comprises a main body part 501 and a rollover prevention part 503. The main body part 501 is installed on the car body, and the rollover prevention part 503 extends from the end of the main body part 501 away from the car body. The rollover prevention part 503 cooperates with the track beam 3000.

[0103] At this time, the main body 501 can be fixedly connected with the vehicle body, so that the anti-rollover part 500 can be stably connected with the vehicle body. The anti-rollover part 503 can be in an integral structure or a split structure with the main body 501. In the case of the integral structure, the anti-rollover part 503 and the main body 501 can be integrally formed. In the case of the split structure, the anti-rollover part 503 and the main body 501 can be detachably or non-detachably connected. The anti-rollover part 503 and the main body 501 of the present application are in an integral structure, so that the connection between the anti-rollover part 503 and the main body 501 is relatively stable. The anti-rollover part 503 extends from the end of the main body 501 away from the vehicle body, and the bent anti-rollover part 503 cooperates with the track beam 3000 to avoid the overturning of the rail vehicle 1000 relative to the track beam 3000.

At this time, the main body 501 is used for connecting the mounting part 505 and the anti-rollover part 503, and the mounting part 505 is used for fixedly connecting with the vehicle body. The mounting part 505 of the present application is connected with the vehicle body through screws, so that the connection between the anti-rollover part 500 and the vehicle body is relatively stable. In the case that the anti-rollover part 500 cooperates with the track beam 3000, the anti-rollover part 500 can effectively avoid the overturning of the rail vehicle 1000 relative to the track beam 3000.

[0105] Please refer to Figure 1 and Figure 6 , the rail transit system 10000 of the present application comprises the track beam 3000 and the rail vehicle 1000 of the above-mentioned embodiments, and the rail vehicle 1000 is movably connected with the track beam 3000.

[0106] In the track beam 3000 of the present application, after the first guide assembly 13 receives the control signal, the first guide assembly 13 can control the working state of the steering part 11, so that the steering part 11 can control the running direction of the running wheel 700. Compared with the current guide device 10, the first guide assembly 13 of the present application cooperates with the steering part 11 to actively adjust the running direction of the running wheel 700, so that the running of the rail vehicle 1000 is less affected by the precision of the track beam 3000, and the running stability of the rail vehicle 1000 is better.

[0107] Please refer to Figure 1 and Figure 6In some embodiments, the track beam 3000 comprises a running beam 3001 and a guide beam 3003, the guide beam 3003 is mounted on the running beam 3001, the guide beam 3003 comprises a guide surface 30032, the extension direction of the guide surface 30032 is consistent with the thickness direction Y of the running beam 3001, and the guide wheel 153 cooperates with the guide surface 30032.

[0108] The running beam 3001 is used to carry the track vehicle 1000, the running wheel 700 of the track vehicle 1000 is in contact with the running beam 3001, so that the track vehicle 1000 can run on the running beam 3001. The guide beam 3003 is used to guide the track vehicle 1000, so that the track vehicle 1000 can run along the track beam 3000, and the track vehicle 1000 can be prevented from derailing.

[0109] Please refer to Figure 1 , Figure 6 and Figure 7 , the guide beam 3003 is detachably or non-detachably mounted on the running beam 3001. In some embodiments, the track beam 3000 comprises two guide beams 3003, the two guide beams 3003 are respectively mounted on opposite sides of the running beam 3001 in the width direction X, and the two guide wheels 153 respectively cooperate with the two guide beams 3003. The extension direction of the central axis of the guide wheel 153 is consistent with the thickness direction Y of the running beam 3001, in the case that the track vehicle 1000 runs to the turning place or the forked intersection of the track beam 3000, the surface of one of the guide wheels 153 is in contact with the guide surface 30032 of one of the guide beams 3003, the guide surface 30032 can guide the guide wheel 153, so that the guide wheel 153 can drive the running wheel 700 to rotate through the steering member 11.

[0110] Please refer to Figure 4 , Figure 6 , Figure 7 and Figure 8 , in some embodiments, the running beam 3001 comprises a running surface 30011, the running wheel 700 cooperates with the running surface 30011, and the bogie 100 is located above the running surface 30011 and is spaced apart from the running surface 30011.

[0111] At present, the middle of the running beam 3001 is usually provided with a groove, the groove is used for the guide member of the track vehicle 1000 to extend into the groove, and the guide member cooperates with the side wall of the groove to guide the running direction of the running wheel 700. Since the bogie 100 is spaced apart from the running surface 30011 in the present application, the running surface 30011 can be a flat surface, the running beam 3001 does not need to be provided with a groove, the structure of the track beam 3000 is relatively simple, and the processing is relatively simple.

[0112] Since the rail vehicle 1000 only requires the running wheels 700 to mate with the running surface 30011, and the bogie 100 does not need to mate with the running surface 30011, the rail vehicle 1000 can also be used on ordinary highways 30000. Figure 8 (As shown). When the rail vehicle 1000 is traveling on the highway 30000, the first guide assembly 13 can actively guide the running wheels 700 through the steering component 11, so that the rail vehicle 1000 can travel along a preset route. The rail vehicle 1000 of this embodiment has strong adaptability to road surface and can reduce the construction cost of the track beam 3000 and the garage.

[0113] Please see Figure 1 , Figure 6 and Figure 7 In some embodiments, the guide beam 3003 includes a body portion 30031 and a stop portion 30033. The extension direction of the body portion 30031 is consistent with the thickness direction Y of the traveling beam 3001. The body portion 30031 is provided with a guide surface 30032. The stop portion 30033 extends from one end of the body portion 30031 away from the traveling beam 3001 by bending. The stop portion 30033 includes a first sub-part 30034 and a second sub-part 30035. The first sub-part 30034 extends from the body portion 30031 toward the center of the traveling beam 3001, and the second sub-part 30035 extends from the body portion 30031 toward the center of the traveling beam 3001. The width of the first sub-part 30034 is adapted to the width of the anti-rollover portion 503.

[0114] Among them, the guide surface 30032 is the side of the main body 30031 facing the center of the traveling beam 3001. When the extension direction of the main body 30031 is consistent with the thickness direction Y of the traveling wheel 700, the extension direction of the guide surface 30032 is consistent with the thickness direction Y of the traveling wheel 700, which facilitates the surface mating between the guide surface 30032 and the guide wheel 153.

[0115] Please see Figure 6 and Figure 7 In one embodiment, the stop portion 30033 may only include a first sub-portion 30034, which bends and extends from the main body portion 30031 toward the center near the traveling beam 3001. In this case, the structure of the guide beam 3003 is relatively simple and the processing is relatively easy. In another embodiment, the stop portion 30033 includes a first sub-portion 30034 and a second sub-portion 30035, with the second sub-portion 30035 extending in a direction away from the first sub-portion 30034. In this case, the overall structure of the guide beam 3003 is more stable, the guide beam 3003 is not easy to shake, and the guide beam 3003 can provide stable guidance for the guide wheel 153.

[0116] Please see Figures 4 to 7The angle between the first sub-portion 30034 and the guide surface 30032 can be an acute angle or a right angle, and the angle between the first sub-portion 30034 and the guide surface 30032 in the embodiment of the present application is a right angle. The first sub-portion 30034 includes two opposite side surfaces in the thickness direction Y of the running beam 3001, and the side surface of the first sub-portion 30034 close to the running surface 30011 cooperates with the rollover prevention portion 503. In the case that the rail vehicle 1000 has a tendency to overturn relative to the rail beam 3000, the rollover prevention portion 503 collides with the side surface of the first sub-portion 30034 close to the running surface 30011, that is, the rollover prevention portion 503 can hook the first sub-portion 30034, thereby avoiding the overturning of the rail vehicle 1000 relative to the rail beam 3000. The number of the rollover prevention members 500 is at least two, and the number of the rollover prevention members 500 can be two, four, six or more, and in the case of multiple rollover prevention members 500, the rollover prevention members 500 can better prevent the rail vehicle 1000 from overturning. Preferably, the multiple rollover prevention members 500 can be uniformly distributed on both sides of the vehicle body in the width direction X of the running beam 3001, so that when the multiple rollover prevention members 500 cooperate with the guide beams 3003 on both sides, the stress on both sides of the vehicle body is more uniform, and the rail vehicle 1000 is less likely to overturn. The number of the rollover prevention members 500 in the present application is two, and the two rollover prevention members 500 are respectively installed on both sides of the vehicle body in the width direction X of the running beam 3001, and the two rollover prevention members 500 respectively cooperate with the two guide beams 3003 to avoid the overturning of the rail vehicle 1000 during running.

[0117] Please refer to Figure 1 , Figure 4 and Figure 5 In one embodiment, the rollover prevention portion 503 is substantially perpendicular to the main body portion 501, that is, the shape of the rollover prevention member 500 is substantially "L" shaped. At this time, in the case that the rail vehicle 1000 has a tendency to overturn relative to the rail beam 3000, the upper surface of the rollover prevention portion 503 can better collide with the side surface of the first sub-portion 30034 close to the running surface 30011 to avoid the overturning of the rail vehicle 1000 during running. At this time, the width of the rollover prevention portion 503 can be the same as the width of the first sub-portion 30034, the width of the rollover prevention portion 503 can be slightly smaller than the width of the first sub-portion 30034, or the width of the rollover prevention portion 503 can be slightly larger than the width of the first sub-portion 30034. In another embodiment, the rollover prevention portion 503 can be a fishhook-shaped structure, and in the case that the rail vehicle 1000 has a tendency to overturn relative to the rail beam 3000, the fishhook-shaped structure can hook the first sub-portion 30034, thereby avoiding the overturning of the rail vehicle 1000 during running.

[0118] Please refer to Figure 1 and Figure 6Further, in some embodiments, the guide beam 3003 further comprises a connecting portion 30036, which is bent from one end of the body portion 30031 close to the running beam 3001 and is used to connect with the running beam 3001. The connecting portion 30036 is fixedly connected with the running beam 3001, so that the guide beam 3003 can be fixedly connected with the running beam 3001, and the guide beam 3003 can be fixed relative to the running beam 3001. At this time, the guide surface 30032 can better guide the guide wheel 153, so as to ensure that the track vehicle 1000 can run along the track beam 3000.

[0119] In some embodiments, the connecting portion 30036 is provided with a connecting hole 30037, the running beam 3001 is provided with a matching hole, the connecting hole 30037 corresponds to the matching hole, and the fastener 30038 extends into the connecting hole 30037 and the matching hole to lock the guide beam 3003 and the running beam 3001. The connecting hole 30037 is a waist-shaped hole.

[0120] The fastener 30038 of the present application can be a bolt, which extends into the matching hole and the connecting hole 30037 to fix the guide beam 3003 to the running beam 3001. In the case where the connecting hole 30037 is a waist-shaped hole, the spacing between the two guide beams 3003 can be adjusted during the installation of the guide beam 3003 to the running beam 3001. Thus, the precision requirement between the two guide surfaces 30032 can be reduced, the machining precision of the guide beam 3003 can be lower, and thus the construction difficulty of the track beam 3000 can be reduced, and the construction cost of the track beam 3000 can be reduced.
