DETAILED DESCRIPTION

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] The core of this invention is to provide a bogie assembly that, through an adjustable structure, can adjust the contact pressure between the horizontal wheel structure and the track beam structure, maintaining the contact pressure within an optimal range under different operating conditions, thereby ensuring the service life of the horizontal wheel structure and the structural strength of the bogie. Another core of this invention is to provide a rail vehicle incorporating the aforementioned bogie assembly.

[0043] The bogie device provided by the present invention includes a bogie 1, a horizontal wheel structure 3, an adjustment structure 2 and a control structure. Figure 1 、 Figure 2 .

[0044] The bogie 1 is the framework of the entire bogie device, and can provide a supporting installation space for the installation of components such as the horizontal wheel structure 3 and the adjustment structure 2.

[0045] The horizontal wheel structure 3 includes a number of horizontal wheels located on both sides of the bogie 1. The horizontal wheels are filled with compressed air and use the side of the track beam structure 7 as the running surface to guide and resist roll. Specifically, the horizontal wheels may include horizontal guide wheels 31 and horizontal stabilizing wheels 32. The horizontal guide wheels 31 guide the vehicle when going through a curve, while the horizontal stabilizing wheels 32 stabilize the vehicle when it is subjected to centrifugal force and wind force, preventing the train from tilting and overturning. Figure 3 As shown, the two horizontal wheels located at a higher position of the track beam structure 7 are horizontal guide wheels 31 , and the horizontal wheel located at a lower position of the track beam structure 7 is a horizontal stabilizing wheel 32 .

[0046] Furthermore, since compressed air is inflated into the horizontal guide wheels 31 and the horizontal stabilizer wheels 32, explosion-proof supports 34 are provided at the bottom of each to prevent tire deflation. Specifically, the explosion-proof supports 34 are connected to the bottom of the horizontal guide wheels 31 or the horizontal stabilizer wheels 32 via the wheel hubs 33. In the event of a tire blowout on the horizontal guide wheels 31 or the horizontal stabilizer wheels 32, the explosion-proof supports 34 can support the track beam structure 7, allowing the bogie assembly to be driven at low speed back to a maintenance location or a vehicle depot for repair or component replacement.

[0047] An adjustment structure 2 is provided between the bogie 1 and several horizontal wheels located on the same side of the bogie 1 . The adjustment structure 2 can drive the horizontal wheels to move so as to adjust the contact pressure between the horizontal wheels and the track beam structure 7 .

[0048] In a specific embodiment, the adjustment structure 2 can drive the horizontal wheel to move along a first direction, which is a direction perpendicular to the side of the track beam structure 7. The movement of the horizontal wheel can change the size of the contact pressure between the horizontal wheel and the track beam structure 7, so that it can be flexibly adjusted according to actual working conditions.

[0049] The specific adjustment structure 2 can drive the movement of the horizontal wheel, and can achieve bidirectional movement by means of a cylinder, an oil cylinder, an electric cylinder, a motor, etc. The bidirectional movement here specifically refers to the bidirectional movement of the horizontal wheel to achieve the effect of adjusting the contact pressure.

[0050] In one embodiment, each horizontal wheel corresponds to an adjustment structure 2 so that targeted adjustments can be made according to specific working conditions during actual driving.

[0051] In another embodiment, several horizontal wheels located on the same side of the bogie 1 are connected to an adjustment structure 2, and the adjustment structure 2 drives several horizontal wheels to move at the same time, so as to achieve a synchronous adjustment effect.

[0052] The control structure signal is connected to the regulating structure 2 , and the control structure can control the operation of several regulating structures 2 corresponding to both sides of the bogie 1 based on the driving condition information.

[0053] The driving condition information here includes specific conditions such as straight sections and curved sections. For example, in a straight section, the contact pressure between the horizontal wheel and the track beam structure 7 can be adjusted to be slightly smaller to avoid wear of the horizontal wheel, reduce driving resistance, and ensure the service life of the horizontal wheel; when passing through a curved section, such as a left turn, the contact pressure between the horizontal wheel and the track beam structure 7 close to the curve needs to be kept reliably clamped to provide guidance and stability, and the contact pressure between the horizontal wheel and the track beam structure 7 needs to be increased, while the contact pressure between the horizontal wheel and the track beam structure 7 away from the curve can be appropriately reduced to ensure reliable turning while avoiding component wear and reducing driving resistance.

[0054] Driving condition information can also include unexpected conditions such as tire blowout. If a tire blowout occurs and the tire needs to be replaced, the contact pressure between the horizontal wheel and the track beam structure 7 needs to be reduced so that the spare fault runner 4 can move to tighten the track beam structure 7 so that the vehicle can travel back to the vehicle depot at a low speed, and the tire can be replaced in the vehicle depot with the help of wheel changing equipment.

[0055] It should be noted that for straight sections and curved sections, the corresponding contact pressure between the horizontal wheels and the track beam structure 7 has an optimal pressure range. During actual operation, the control structure can automatically adjust the contact pressure between the horizontal wheels and the track beam structure 7 according to road conditions, so as to effectively reduce the wear rate of the horizontal wheels and ensure the frame strength of the bogie 1.

[0056] It should be further explained that the control structure may obtain driving condition information by obtaining road section information through a front-end camera of the vehicle body and obtaining tire pressure information through a real-time tire pressure monitoring system to determine whether a tire has burst, etc., which will not be elaborated here.

[0057] In this embodiment, the setting of the adjustment structure 2 enables the horizontal wheel to be adjusted relative to the track beam structure 7, so that the contact pressure between the horizontal wheel and the track beam structure 7 can be automatically adjusted according to the actual driving condition information, so that the contact pressure is in the optimal contact pressure range under different driving conditions, effectively reducing the wear rate of the horizontal wheel and ensuring the frame strength of the bogie 1.

[0058] On the basis of the above embodiment, a guide member 15 is provided on the bogie 1 at a position corresponding to any horizontal wheel. The guide member 15 is used to guide the horizontal wheel when the adjustment structure 2 drives the horizontal wheel to move.

[0059] The moving direction of the horizontal wheel is specifically a first direction perpendicular to the track beam structure 7. Through the setting of the guide member 15, guidance can be provided for each horizontal wheel during movement, ensuring reliable and precise adjustment of the contact pressure between the horizontal wheel and the track beam structure 7.

[0060] The specific setting direction of the guide member 15 is consistent with the moving direction of the horizontal wheel. When the adjustment structure 2 drives the horizontal wheel to move, it moves reliably and accurately along the guide of the guide member 15. Specifically, the guide member 15 can be in the form of a guide rail, a slide rail, or a guide block or a guide roller.

[0061] If the guide member 15 is in the form of a guide rail, after the adjustment structure 2 is connected to the horizontal wheel, a guide portion that can cooperate with the guide rail is provided on the horizontal wheel or the adjustment structure 2. By moving the guide portion along the guide rail, the accuracy and reliability of the horizontal wheel movement route can be guaranteed.

[0062] If the guide member 15 is in the form of a guide block, after the adjustment structure 2 is connected to the horizontal wheel, a guide rail that can cooperate with the guide block is provided on the horizontal wheel or the adjustment structure 2. Through the relative sliding of the guide rail and the guide block, the accuracy and reliability of the horizontal wheel movement route can be guaranteed.

[0063] In this embodiment, a guide member 15 is provided at each horizontal wheel to provide a reliable guiding effect for the movement of each horizontal wheel, thereby ensuring the reliability and effectiveness of the adjustment structure 2 in adjusting the contact pressure.

[0064] In this embodiment, the arrangement of the guide member 15 also needs to consider preventing the horizontal wheel from over-limiting. Over-limiting movement here specifically refers to over-limiting movement of the horizontal wheel when moving in both directions relative to the side of the track beam structure 7. Reliable limiting can be ensured by providing a limiter or a light sensor at both ends of the guide member 15. The limiter is mechanically limited, while the light sensor is limited by induction.

[0065] Based on any of the above embodiments, the adjustment structure 2 includes a moving part 21, a fixed part connected to the moving part 21, the fixed end of the moving part 21 is connected to the bogie 1, the moving end of the moving part 21 is connected to the fixed part, the fixed part is connected to the horizontal wheel and can slide relative to the guide part 15.

[0066] like Figure 5 、 Figure 6 As shown, the movable member 21 can specifically drive the guide member 15 fixed relative to the bogie 1 to slide. The movable member 21 is specifically a power mechanism that can provide linear motion, such as a pneumatic cylinder, an oil cylinder, an electric cylinder, a ball screw motor, etc., without specific limitation.

[0067] In one embodiment, the movable member 21 is a cylinder. The fixed end of the cylinder is fixed to the bogie 1, and the movable end of the cylinder is connected to the horizontal wheel to drive the horizontal wheel. The cylinder is connected to the control structure signal. The control structure controls the contact pressure between the horizontal wheel and the track beam structure 7 by extending and retracting the cylinder.

[0068] Regarding the form in which the moving end of the moving part 21 is connected to the fixed seat 22, the moving end can pass through the mounting position of the bogie 1 and then be connected to the fixed seat 22. The mounting hole 17 of the bogie 1 can also serve as a limit for the moving part 21 when it moves, so as to ensure the reliability and stability of the operation of the moving part 21.

[0069] like Figure 5 and Figure 6 As shown, the guide structures of both the horizontal guide wheel 31 and the horizontal stabilizing wheel 32 are the guide parts 15, and the power mechanisms are the moving parts 21, but the difference is that the fixed end of the moving part 21 of the horizontal stabilizing wheel 32 needs to be connected to the bogie 1 with the help of a transition seat 23. This is an adaptive change based on the different positions of the horizontal guide wheel 31 and the horizontal stabilizing wheel 32. The transition seat 23 and the bogie 1 are detachably connected.

[0070] Based on any of the above embodiments, please refer to Figure 1 , and also includes a running wheel structure 5 and a faulty runner 4 provided on the bogie 1. The faulty runner 4 can move to contact or move away from the track beam structure 7. When an abnormal situation occurs in the running wheel structure 5, the control structure can control the adjustment structure 2 to reduce the contact pressure between the horizontal wheel and the track beam structure 7, and can control the faulty runner 4 to move to contact the track beam structure 7 to replace the corresponding running wheel structure 5.

[0071] Please refer to Figure 8The running wheel structure 5 is a component that can provide the vehicle body with moving power. Specifically, the running wheel structure 5 may include a hydraulic motor 53, a reducer 52, a running wheel 51 and a connecting seat 54, wherein the connecting seat is installed on the bogie 1, and traction and braking force are provided by the hydraulic motor 53 and the reducer 52. The running wheel 51 adopts a hollow rubber tire filled with compressed air.

[0072] Under normal driving conditions, the running wheel 51 contacts the track beam structure 7 to achieve running through friction and motor driving force. The faulty runner 4 is set away from the track beam structure 7 and does not interfere with the normal operation of the running wheel 51. When an abnormal situation occurs, such as the running wheel 51 is stuck or the running wheel has a flat tire, the faulty runner 4 is needed to replace the abnormal running wheel 51 to be able to perform self-rescue in the event of an abnormal situation, so that the bogie device can travel back to the vehicle depot, effectively saving rescue time.

[0073] When an abnormal situation occurs in the running wheel structure 5, the adjustment structure 2 can reduce the contact pressure between the horizontal wheel and the track beam structure 7, so that the faulty runner 4 can move to the contact track beam structure 7 more effortlessly, and can replace the abnormal running wheel 51 by contacting the track beam structure 7, thereby avoiding engineering vehicles occupying the main line and affecting the normal operation of the vehicle.

[0074] In this embodiment, reducing the contact pressure between the horizontal wheel and the track beam structure 7 may refer to adjusting it to zero, or to an allowable smaller value.

[0075] In addition, due to the setting of the adjustment structure 2, when the bogie device is able to travel back to the vehicle depot, the horizontal wheel can be controlled to move to the side of the track beam structure 7, and combined with the straddle-type wheel changing equipment, the running wheel 51 can be replaced without separating the bogie 1 from the car body, making the disassembly and replacement of the running wheel 51 more convenient and improving the maintenance efficiency.

[0076] On the basis of any of the above embodiments, a monitoring element for monitoring the deflection of the bogie 1 is further included, and the control structure can control the moving distance of the faulty runner 4 according to the monitoring information of the monitoring element to restore the bogie 1 to a horizontal state.

[0077] Under normal driving conditions, the bogie 1 should remain in a horizontal state. In the event of a tire blowout on the running wheel 51, the bogie 1 will deflect. While replacing the running wheel 51 with a tire blowout by the faulty runner 4, the bogie 1 also needs to be adjusted. The adjustment here means restoring it to a horizontal state.

[0078] In a specific embodiment, during adjustment, several horizontal wheels on both sides of the bogie 1 can be separated from contact with the track beam structure 7 through the adjustment structure 2, so as to avoid vertical friction between the horizontal wheels and the side of the track beam structure 7 when the tilted end of the bogie 1 is lifted, which is more conducive to alleviating the fault rescue condition of the running wheel 51 and extending the service life of the horizontal wheels.

[0079] In this embodiment, the monitoring element specifically monitors the deflection of the bogie 1 by monitoring the position information of a fixed point of the bogie 1 to determine whether deflection occurs. The specific monitoring element can be a position detection sensor or other forms as long as it can realize deflection monitoring.

[0080] In the event of a tire blowout, the deflection conditions of the running wheels 51 on both sides of the bogie 1 corresponding to the tire blowout may be inconsistent, and the movement of the corresponding horizontal wheels can be controlled separately through the control structure to ensure the adjustment effect of the bogie 1.

[0081] Based on any of the above embodiments, please refer to Figure 7 The fault traveler 4 includes: a safety wheel 42; a driving member 41, the fixed end of the driving member 41 is fixed to the bogie 1, and the movable end of the driving member 41 is rotatably connected to the safety wheel 42 through the shaft sleeve 43. The movable end of the driving member 41 can drive the safety wheel 42 to move in a direction perpendicular to the driving direction of the running wheel structure 5.

[0082] In this embodiment, the fault traveler 4 specifically includes a driving member 41, a safety wheel 42 and a sleeve 43, wherein the safety wheel 42 is a component that can lift the running wheel 51 to run, and the driving member 41 can move the safety wheel 42 to contact the track beam structure 7 or away from the track beam structure 7. Figure 2 When the running wheel 51 is running normally, the safety wheel 42 is set away from the track beam structure 7 to avoid interference with the running wheel 51; please refer to Figure 7 When the running wheel 51 has a tire blowout or is stuck, the adjustment structure 2 reduces the contact pressure between the horizontal wheel and the track beam structure 7 to facilitate the lifting of the safety wheel 42. The safety wheel 42 can move quickly to contact the track beam structure 7 to replace the running wheel 51 for support and movement, avoiding the construction vehicle occupying the main line and affecting the normal operation of the vehicle.

[0083] In this embodiment, the faulty runner 4 is arranged in the bogie 1, specifically on one side of the running wheel 51. If there are two running wheels 51, two faulty runners 4 are correspondingly provided to serve as backup when the two running wheels 51 fail.

[0084] In this embodiment, if a tire blowout occurs, in addition to the safety wheel 42 contacting the track beam structure 7, the safety wheel 42 needs to be moved to lift the tilted end of the bogie 1 so that the bogie 1 can be adjusted.

[0085] In this embodiment, the shaft sleeve 43 is provided mainly to realize the rotation of the safety wheel 42 relative to the driving member 41 and to enable the driving member 41 to indirectly drive the safety wheel 42 to move.

[0086] On the basis of any of the above embodiments, at least two driving members 41 are provided on both sides of the traveling direction of the running wheel 51 of the running wheel structure 5 .

[0087] In order to ensure the stability and reliability of the movement and adjustment of the safety wheel 42, at least two driving members 41 are provided on both sides of the traveling direction of the running wheel 51. When the safety wheel 42 needs to move, the at least two driving members 41 located on both sides of the safety wheel 42 are synchronously driven to smoothly and reliably move the safety wheel 42 to the desired position.

[0088] At least two driving members 41 are distributed on both sides of the safety wheel 42 and connected to the shaft sleeve 43 , that is, at least two driving members 41 can be connected to the safety wheel 42 through the shaft sleeve 43 to drive the movement of the safety wheel 42 .

[0089] In this embodiment, the driving member 41 may specifically be a pneumatic cylinder, an oil cylinder, an electric cylinder or the like.

[0090] Based on any of the above embodiments, the bogie 1 includes two side beams 12 arranged opposite to each other, and each side beam 12 is provided with a connecting portion 18. The connecting portions 18 provided on the two side beams 12 are arranged in an staggered manner to be able to connect at least two running wheel structures 5.

[0091] like Figure 1 、 Figure 4 As shown, taking the arrangement of two running wheel structures 5 as an example, each of the two side beams 12 is provided with a connecting portion 18, and the two connecting portions 18 formed by the two side beams 12 are staggered to ensure better stress conditions and load-bearing capacity, thereby ensuring reliable support for the running wheel structure 5.

[0092] Based on any of the above embodiments, please refer to Figure 4 The bogie 1 also includes an end beam 11 connected to the two side beams 12, and a cross beam 13 located between the two end beams 11. The end beam 11 is provided with a mounting seat 16 for installing the faulty runner 4 on the side close to the cross beam 13, and the side beam 12 is provided with a guide member 15 for guiding the movement of the horizontal wheel on the side close to the cross beam 13.

[0093] The middle portion of the side beam 12 is used to connect the cross beam 13, which can be connected to the central traction structure 6 to transmit power to the vehicle body. Figure 9 The central traction structure 6 consists of a center pin support 63, a traction rubber pile mounted on the center pin support 63, a center pin body 61 fixed to the center pin support 63, and a transverse stop 62 and a longitudinal stop mounted on the bogie 1. The transverse stop 62 and the longitudinal stop are used to limit the position during steering. The center pin body 61 is fastened to the car body to transmit the vehicle's traction and braking forces and to accommodate various relative movements between the car body and the bogie 1.

[0094] A vertical beam 14 is provided in a direction perpendicular to the side beam 12 and the end beam 11. The vertical beam 14 is connected to the middle of the side beam 12 and can be used to connect the secondary suspension structure 8 to transmit the load and force between the car body and the bogie 1. Specifically, it transmits the vertical force and horizontal force between the car body and the bogie 1 to reduce the impact vibration between the car body and the bogie 1. Please refer to Figure 10 The secondary suspension structure 8 consists of a multifunctional bracket 81, an hourglass spring 84 installed between the multifunctional bracket 81 and the bogie 1, a lateral shock absorber 85, a vertical shock absorber 82, and a protective chain 83. The shock absorber and the elastic hourglass spring 84 are used to improve the vehicle's operating performance.

[0095] In addition, the secondary suspension structure 8 is arranged diagonally along the center point of the bogie 1, which greatly improves the curve passability of the bogie 1.

[0096] In summary, the bogie device has at least the following beneficial effects:

[0097] By adjusting the extension and retraction of the moving parts 21 on both sides of the bogie 1, the bogie 1 can be adjusted in straight sections, curved sections and other sections, or when the running wheels 51 fail or the horizontal wheels need to be replaced and repaired. The contact pressure between the horizontal wheels and the side of the track beam can be adjusted to be within the optimal range, which can effectively extend the service life of the horizontal wheels and facilitate the disassembly and maintenance of the horizontal wheels.

[0098] If a running wheel 51 becomes stuck or has a tire blown during mainline rescue or shunting operations, the safety wheel 42 can be quickly deployed to replace the faulty running wheel 51, preventing engineering vehicles from occupying the mainline and disrupting normal train operations. Simultaneously with the deployment of the safety wheel 42, the horizontal wheels on either side of the faulty running wheel 51 are retracted, allowing the bogie 1 to return to a horizontal position supported by the faulty runner 4. This prevents vertical friction between the horizontal wheels and the sides of the track beam structure 7 during the jacking of the bogie frame, further facilitating the rescue of a running wheel failure and extending the service life of the horizontal wheels.

[0099] By controlling the horizontal wheel side moving part 21 to retract so that the horizontal wheel is separated from the side of the track beam structure 7, the driving part 41 of the faulty runner 4 is controlled to lift so that the safety wheel 42 contacts the side of the track beam structure 7 to support the bogie 1. In combination with the straddle-type monorail wheel changing equipment, the running wheel of the bogie 1 can be replaced without separating the bogie 1 from the car body, making the disassembly and replacement of the running wheel 51 more convenient.

[0100] In addition to the above-mentioned bogie device, the present invention also provides a rail vehicle including the bogie device disclosed in the above-mentioned embodiment. For the structures of other parts of the rail vehicle, please refer to the prior art and will not be described in detail herein.
