Technical Field

[0001] The present application relates to the technical field of rail vehicles, and particularly relates to a gearbox suspension seat and a bogie frame of a rail vehicle. Background Art

[0002] In rail vehicles, a gearbox needs to be arranged on the bogie. For the installation and use of the gearbox, a gearbox suspension seat is required.

[0003] In the existing system, the gearbox suspension seat is an important component in the bogie of a rail vehicle. The gearbox suspension seat connects the gearbox and the bogie, enabling the output of the gearbox to be transmitted to the wheelset, thereby driving the vehicle forward or backward. It can be seen that the gearbox suspension seat is mainly used to support the gearbox to ensure that the gearbox is stably installed on the bogie. However, the current gearbox suspension seat is manufactured with a relatively simple structure, and the structure of the gearbox suspension seat for connecting with the gearbox is difficult to meet the requirements of normal service life during the actual operation of the rail vehicle, and it is easy to cause the gearbox to disengage from the gearbox suspension seat.

[0004] Therefore, it is necessary for those skilled in the art to timely provide a gearbox suspension seat with high anti-disengagement stability and reliability. Utility Model Content

[0005] The purpose of the present application is to provide a gearbox suspension seat and a bogie frame of a rail vehicle, which can improve the anti-disengagement stability and reliability and solve the problem that the gearbox body is easily disengaged from the gearbox suspension seat.

[0006] To achieve the above purpose, the present application provides a gearbox suspension seat, including:

[0007] A suspension seat body, which is used to be installed on the crossbeam module of the bogie frame. The suspension seat body includes a connection seat, and the connection seat is used to connect the gearbox body;

[0013] In some embodiments, second connecting holes are further provided on both of the pair of connecting arms, and the second connecting holes extend along the second direction;

[0014] The second connecting assembly includes a pair of second connecting bolts. The second connecting bolts pass through the anti-disengagement member and are threadedly connected to the corresponding second connecting holes, so that the anti-disengagement member is fastened to the connecting seat.

[0015] In some embodiments, convex platforms protruding along the second direction are provided at the ends of both of the pair of connecting arms, and the second connecting holes are provided on the corresponding convex platforms.

[0016] In some embodiments, the dimension of the convex platform along the first direction is smaller than the dimension of the corresponding connecting arm along the first direction, so that avoidance spaces are formed on both sides of the convex platform along the first direction;

[0017] Two pairs of extension pieces are provided on the side of the anti-disengagement member close to the connecting seat, and any one pair of the extension pieces extends along the second direction to form a groove;

[0018] When the anti-disengagement member is connected to the connecting seat, the groove is fitted with the corresponding convex platform in an embedded manner, and the extension piece is accommodated in the corresponding avoidance space.

[0019] In some embodiments, a connecting groove is provided at one end of the hanging seat body facing away from the connecting seat, and the inner wall of the connecting groove is used for welding on the crossbeam module of the bogie frame.

[0020] In some embodiments, the hanging seat body further includes a narrowing structure. The narrowing structure is provided between the connecting groove and the connecting seat. The narrowing structure is used to reduce the weight of the hanging seat body and provide an operating space for the welding of the hanging seat body and the crossbeam module of the bogie frame.

[0021] In some embodiments, an avoidance groove is provided at the top of the anti-disengagement member. The dimension of the avoidance groove along the third direction is greater than or equal to the dimension of the hanging rod end of the gearbox body along the third direction to avoid the end of the hanging rod of the gearbox body, where the third direction is perpendicular to the first direction and the third direction is perpendicular to the second direction.

[0022] In some embodiments, the hanger body is an integrally forged hanger body.

[0023] The present application further provides a bogie frame of a rail vehicle, including a crossbeam module, and further including the gearbox hanger as described in any one of the above.

[0024] Compared with the above background art, the gearbox hanger provided by the embodiments of the present application includes a hanger body, a first connection assembly, an anti - detachment member, and a second connection assembly.

[0025] It can be seen that when connecting the gearbox body, the gearbox hanger provided by the present application connects the suspension rod of the gearbox body and the connection seat through the first connection assembly. At the same time, an anti - detachment member is added, and the anti - detachment member and the connection seat are connected through the second connection assembly. The anti - detachment member is provided with an anti - detachment hole that cooperates with the protruding structure of the gearbox body. That is to say, on the basis of the first connection assembly connecting the suspension rod of the gearbox body and the connection seat, the second connection assembly is used to connect the anti - detachment member and the connection seat, and the anti - detachment member plays an anti - detachment role, ensuring the stability and reliability of the connection between the gearbox body and the gearbox hanger.

[0026] With such a setting, compared with the traditional gearbox hanger, the gearbox hanger provided by the present application improves the structure for connecting with the gearbox body. Specifically, the suspension rod of the gearbox body and the connection seat are connected by the first connection assembly, and the anti - detachment member and the connection seat are connected by the second connection assembly. After the suspension rod of the gearbox body is damaged or the first connection assembly fails, the anti - detachment member can inhibit the up - and - down flipping of the gearbox body and prevent the gearbox body from detaching from the gearbox hanger, thereby improving the stability and reliability of the connection between the gearbox body and the gearbox hanger, enabling the structure for connecting with the gearbox body on the gearbox hanger to meet the requirements of normal service life during the actual operation of the rail vehicle, and solving the problem that the gearbox body is prone to detaching from the gearbox hanger.

[0039] To enable those skilled in the art of this technology to better understand the solution of the present application, the following will further elaborate on the present application in combination with the drawings and specific embodiments.

[0040] It should be noted that the orientation words such as "upper end, lower end, left side, right side" described below are defined based on the drawings of the specification.

[0041] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 which is the assembly schematic diagram of the gearbox suspension seat in the embodiment of the present application; Figure 2 is Figure 1 the connection schematic diagram of the gearbox suspension seat shown and the suspension rod of the gearbox body; Figure 3 is Figure 1 the structural schematic diagram of the suspension seat body in the gearbox suspension seat shown.

[0042] The gearbox suspension seat provided by the embodiment of the present application is an important part of the bogie frame of the rail vehicle, and this gearbox suspension seat is used to support and fix the gearbox body 50.

[0043] In the rail transit vehicle, the bogie is a key component for vehicle operation, and the gearbox suspension seat ensures the stability and safety of the gearbox body 50. The design and manufacturing quality of the gearbox suspension seat directly affect the operation quality and driving safety of the vehicle. In the bogie structure of the present application, the gearbox suspension seat and the motor suspension seat are installed on the crossbeam module 60 together to ensure the effective transmission of traction force and the stability of the vehicle.

[0044] The gearbox suspension seat provided by the embodiment of the present application includes a suspension seat body 10, a first connection component 20, an anti-disengagement component 30 and a second connection component 40.

[0045] The suspension seat body 10 is used to be installed on the crossbeam module 60 of the bogie frame. The suspension seat body 10 includes a connection seat 11, and the connection seat 11 is used to connect the gearbox body 50; the first connection component 20 is used to be arranged at the connection part of the connection seat 11 and the suspension rod 51 of the gearbox body 50 along the first direction to connect the suspension rod 51 of the gearbox body 50 to the connection seat 11.

[0046] Specifically, the lower end of the suspension rod 51 of the gearbox body 50 is connected to the gearbox body 50, the upper end of the suspension rod 51 of the gearbox body 50 is installed on the connection seat 11 of the suspension seat body 10. The upper end of the suspension rod 51 of the gearbox body 50 extends two connection ends on both sides along the third direction, and connection surfaces are provided on both connection arms 111 of the connection seat 11. The two connection ends are respectively lapped on the connection surfaces of the two connection arms 111, so that the suspension rod 51 of the gearbox body 50 is suspended on the connection seat 11. During installation, the two connection ends at the upper end of the suspension rod 51 of the gearbox body 50 are respectively lapped on the connection surfaces of the two connection arms 111, and the first connection component 20 is used to penetrate through the connection part of the connection seat 11 and the suspension rod 51 of the gearbox body 50 along the first direction, so as to achieve the purpose of connecting the above-mentioned connection seat 11 and the suspension rod 51 of the gearbox body 50.

[0047] The anti - detachment member 30 is provided on the connecting seat 11. The anti - detachment member 30 is provided with an anti - detachment hole 31. The anti - detachment hole 31 is used for the protruding structure 52 of the gearbox body 50 to pass through, so as to prevent the gearbox body 50 from detaching from the connecting seat 11; The second connecting assembly 40 is used to be arranged at the connection between the connecting seat 11 and the anti - detachment member 30 along a second direction perpendicular to the first direction, so as to connect the anti - detachment member 30 to the connecting seat 11.

[0048] Specifically, the anti - detachment hole 31 on the anti - detachment member 30 can be a square hole or a circular hole. After the suspension rod 51 of the gearbox body 50 is installed on the connecting seat 11, the protruding structure 52 of the gearbox body 50 passes through the anti - detachment hole 31, and the protruding structure 52 of the gearbox body 50 is suspended in the anti - detachment hole 31, that is, there is a preset gap between the protruding structure 52 of the gearbox body 50 and the inner walls around the anti - detachment hole 31. The protruding structure 52 of the gearbox body 50 can be arranged along the second direction, and the protruding structure 52 of the gearbox body 50 is perpendicular to the suspension rod 51 of the gearbox body 50. In this way, after the suspension rod 51 of the gearbox body 50 is damaged or the first connecting assembly 20 fails, the anti - detachment member 30 can restrain the up - and - down flipping of the gearbox body 50 and can prevent the gearbox body 50 from detaching from the gearbox suspension seat, thereby improving the stability and reliability of the connection between the gearbox body 50 and the gearbox suspension seat.

[0049] It should be noted that the above - mentioned first direction is the Z - axis direction as shown in Figure 2 shown, the second direction is the X - axis direction as shown in Figure 2 shown, and the third direction is the Y - axis direction as shown in Figure 2 shown. Among them, the first direction, the second direction and the third direction are perpendicular to each other.

[0050] It can be understood that the design of the anti - detachment member 30 can ensure the safety and stability of the gearbox body 50 in the bogie structure. The specific functions brought by the anti - detachment member 30 include:

[0051] Flipping inhibition: The anti - detachment member 30 can prevent the gearbox body 50 from flipping up and down when subjected to vertical or lateral forces. Such flipping may cause damage to the internal parts of the gearbox body 50 and even may cause more serious mechanical failures.

[0052] Detachment prevention: Even when the suspension rod 51 of the gearbox body 50 or the first connecting assembly 20 fails, the anti - detachment member 30 can ensure that the gearbox body 50 does not fall off the suspension seat, which is crucial for maintaining the running safety of the vehicle.

[0053] Providing backup support: The anti - detachment member 30 provides backup support when the main support structure (the first connecting assembly 20) fails, ensuring that the gearbox body 50 remains in place and continues to perform its functions.

[0054] Increasing redundancy: The design of the anti - detachment part 30 increases the redundancy of the entire system. Even if there is a problem with the main connection point, the anti - detachment part 30 can still maintain the structural integrity.

[0055] Improving reliability: By designing the anti - detachment part 30, the reliability of the gearbox hanger system is improved, reducing unexpected shutdowns and maintenance costs caused by connection failures.

[0056] For the gearbox hanger provided in this application, when connecting to the gearbox body 50, the boom 51 of the gearbox body 50 and the connecting seat 11 are connected through the first connecting component 20. At the same time, an anti - detachment part 30 is added, and the anti - detachment part 30 and the connecting seat 11 are connected through the second connecting component 40. The anti - detachment part 30 is provided with an anti - detachment hole 31 that cooperates with the protruding structure 52 of the gearbox body 50. That is to say, on the basis of the first connecting component 20 connecting the boom 51 of the gearbox body 50 and the connecting seat 11, the second connecting component 40 is used to connect the anti - detachment part 30 and the connecting seat 11. The anti - detachment part 30 plays an anti - detachment role, ensuring the stability and reliability of the connection between the gearbox body 50 and the gearbox hanger.

[0057] With such a setting, compared with the traditional gearbox hanger, the gearbox hanger provided in this application improves the structure for connecting to the gearbox body 50. Specifically, the boom 51 of the gearbox body 50 and the connecting seat 11 are connected by the first connecting component 20, and the anti - detachment part 30 and the connecting seat 11 are connected by the second connecting component 40. After the boom 51 of the gearbox body 50 is damaged or the first connecting component 20 fails, the anti - detachment part 30 can inhibit the up - and - down flipping of the gearbox body 50 and prevent the gearbox body 50 from detaching from the gearbox hanger, thereby improving the stability and reliability of the connection between the gearbox body 50 and the gearbox hanger, enabling the structure for connecting to the gearbox body 50 on the gearbox hanger to meet the requirements of normal service life during the actual operation of the rail vehicle, and solving the problem that the gearbox body 50 is prone to detaching from the gearbox hanger.

[0058] In some embodiments, the connecting seat 11 is U - shaped. The connecting seat 11 includes a pair of connecting arms 111. A U - shaped groove is formed between the pair of connecting arms 111 for the boom 51 of the gearbox body 50 to pass through. Connecting surfaces are provided on both of the pair of connecting arms 111. The connecting surfaces are horizontal planes, and the two connecting surfaces are used to contact and fit with the two connecting ends extending from both sides of the upper end of the boom 51 of the gearbox body 50 in the third direction.

[0059] To facilitate the connection between the connecting seat 11 and the first connection assembly 20, first connection holes 112 are provided on a pair of connecting arms 111, and the first connection holes 112 extend in the first direction; the first connection assembly 20 includes a pair of first connection bolts, and the first connection bolts pass through the suspension rod 51 of the gearbox body 50 and are threadedly connected to the corresponding first connection holes 112, so that the suspension rod 51 of the gearbox body 50 is fastened to the connecting seat 11.

[0060] In this way, the two connection ends extending from both sides of the upper end of the suspension rod 51 of the gearbox body 50 in the third direction are respectively lapped on the connection surfaces of the two connecting arms 111, so that the suspension rod 51 of the gearbox body 50 is suspended on the connecting seat 11. During installation, the two connection ends of the upper end of the suspension rod 51 of the gearbox body 50 are respectively lapped on the connection surfaces of the two connecting arms 111, and two first connection bolts are used to pass through the corresponding connection ends on the suspension rod 51 of the gearbox body 50 and then threadedly connected to the corresponding first connection holes 112, so as to achieve the purpose of fixing the suspension rod 51 of the gearbox body 50 to the connecting seat 11.

[0061] To facilitate the connection between the connecting seat 11 and the second connection assembly 40, second connection holes 113 are further provided on a pair of connecting arms 111, and the second connection holes 113 extend in the second direction; the second connection assembly 40 includes a pair of second connection bolts, and the second connection bolts pass through the anti-disengagement member 30 and are threadedly connected to the corresponding second connection holes 113, so that the anti-disengagement member 30 is fastened to the connecting seat 11.

[0062] During installation, the two hole positions of the anti-disengagement member 30 are respectively aligned with the two second connection holes 113, and two second connection bolts are used to pass through the corresponding hole positions on the anti-disengagement member 30 and then threadedly connected to the corresponding second connection holes 113, so as to achieve the purpose of fixing the anti-disengagement member 30 to the connecting seat 11.

[0063] It should be emphasized that the anti-disengagement member 30 is arranged at the end of the gearbox suspension seat and is connected by second connection bolts. The suspension rod 51 of the gearbox body 50 is installed at the end of the gearbox suspension seat and is located inside the anti-disengagement member 30 and is connected by first connection bolts. Such a setting is convenient for disassembly and does not affect the installation and disassembly of the gearbox body 50.

[0064] In some embodiments, convex platforms 114 protruding in the second direction are provided at the ends of a pair of connecting arms 111. It can be understood that the convex platforms 114 protrude in a direction away from the first connection holes 112, and the second connection holes 113 are provided on the corresponding convex platforms 114.

[0065] With such a setting, the two first connection holes 112 and the two second connection holes 113 are integrally arranged on the same connection base 11, and the directions of the first connection hole 112 and the second connection hole 113 are perpendicular to each other. Two-level connection structures can be arranged on the effective structure, thereby ensuring the stability and reliability of the connection between the gearbox body 50 and the gearbox suspension seat. In this way, on the basis of ensuring structural compactness, the space utilization rate can be improved.

[0066] In other words, the second connection bolt for installing the gearbox anti-disengagement structure (anti-disengagement member 30) and the first connection bolt for installing the suspension rod 51 of the gearbox body 50 are jointly arranged on one seat, with a compact structure, reasonable space layout, and no interference.

[0067] In some embodiments, the dimension of the boss 114 along the first direction is smaller than the dimension of the corresponding connecting arm 111 along the first direction, so that avoidance spaces 115 are formed on both sides of the boss 114 along the first direction; correspondingly, in order to adapt to the structure of the connection base 11, two pairs of extension pieces 32 are provided on one side of the anti-disengagement member 30 close to the connection base 11, and any pair of extension pieces 32 extends along the second direction to form a groove 33.

[0068] It should be noted that the groove 33 is a U-shaped groove. That is to say, a pair of extension pieces 32 and the anti-disengagement member 30 jointly form a U-shaped structure, and this U-shaped structure just fits with the boss 114.

[0069] In this way, when the anti-disengagement member 30 is connected to the connection base 11, the groove 33 is fitted with the corresponding boss 114, and the extension piece 32 is received in the corresponding avoidance space 115.

[0070] It can be seen that a boss 114 is provided at the end of the gearbox suspension seat, and a groove 33 is provided on the gearbox anti-disengagement structure (anti-disengagement member 30). The boss 114 and the corresponding groove 33 are in a small clearance fit. When the anti-disengagement member 30 receives a large impact force, the second connection bolt can be prevented from bearing shear force and the second connection bolt can be avoided from failing.

[0071] It should be noted that the design of the gearbox suspension seat usually needs to consider various factors, including bearing capacity, stability, maintenance convenience, and safety. Providing a boss 114 at the end of the gearbox suspension seat and providing a groove 33 on the gearbox anti-disengagement structure (anti-disengagement member 30), the beneficial effects mainly include:

[0072] 1. The design of the boss 114 at the end of the gearbox suspension seat can provide an additional support point, increase the contact area between the suspension seat and the gearbox body 50, thereby improving the stability and bearing capacity of the structure.

[0073] 2. A groove 33 is provided on the anti-displacement member 30. Compared with further adding an anti-displacement structure to the gearbox body 50 on the basis of the anti-displacement member 30, the groove 33 can cooperate with the boss 114 at the end of the suspension seat to form a mechanical locking mechanism to prevent the gearbox body 50 from displacing or falling off when subjected to impact or vibration.

[0074] 3. By precisely controlling the gap between the boss 114 and the groove 33, a tight fit can be achieved while maintaining a certain degree of flexibility to accommodate temperature changes or minor mechanical deformations.

[0075] 4. When subjected to a large impact force, if the connection between the gearbox body 50 and the gearbox suspension seat only depends on the second connecting bolt, the second connecting bolt may bear excessive shear force, resulting in the failure or breakage of the second connecting bolt. Through the design of the boss 114 and the groove 33, the impact force can be transmitted through the structural member itself rather than relying entirely on the second connecting bolt, thereby protecting the second connecting bolt from damage.

[0076] 5. This design can effectively avoid the gearbox body 50 falling off due to the failure of the second connecting bolt, improving the safety of the entire system.

[0077] 6. A reasonable fit gap also facilitates daily inspection and maintenance work, and the status of the second connecting bolt and the anti-displacement member 30 can be inspected without disassembling the entire system.

[0078] 7. This design can adapt to different working environments and conditions, including temperature changes, vibration, impact, etc., ensuring the stable operation of the gearbox.

[0079] In some embodiments, for the convenience of connecting the suspension seat body 10 and the crossbeam module 60, a connecting groove 12 is provided at one end of the suspension seat body 10 away from the connecting seat 11, and the inner wall of the connecting groove 12 is used for welding on the crossbeam module 60 of the bogie frame.

[0080] The structure and dimensions of the connecting groove 12 are adapted to the structure and dimensions of the crossbeam body of the crossbeam module 60. For example, the connecting groove 12 can be an arc-shaped groove.

[0081] In some embodiments, the suspension seat body 10 further includes a narrowing structure 13, and the narrowing structure 13 is provided between the connecting groove 12 and the connecting seat 11. The narrowing structure 13 is used to reduce the weight of the suspension seat body 10, and the narrowing structure 13 is also used to provide an operating space for welding the suspension seat body 10 and the crossbeam module 60 of the bogie frame.

[0082] It can be understood that the narrowing structure 13 is similar to the abdomen of an I-beam structure, and the structure where the connection groove 12 is located at one end and the connection seat 11 at the other end are similar to the wings of an I-beam structure. Setting the narrowing structure 13 in the middle of the gearbox hanger not only helps to reduce weight on the basis of ensuring the structural strength of the hanger body 10, but also provides an operating space for the welding of the hanger body 10 and the crossbeam module 60 of the bogie frame, which is conducive to the smooth progress of the welding operation.

[0083] In some embodiments, an avoidance groove 34 is provided at the top of the anti-disengagement member 30, and the dimension of the avoidance groove 34 in the third direction is greater than or equal to the dimension of the suspension rod 51 of the gearbox body 50 in the third direction to avoid the end of the suspension rod 51 of the gearbox body 50 (the end of the suspension rod 51 is an annular structure), wherein the third direction is perpendicular to the first direction and the third direction is perpendicular to the second direction.

[0084] In some embodiments, the hanger body 10 is an integrally forged hanger body 10.

[0085] The hanger body 10 adopts an integral forging process and has the following characteristics and advantages:

[0086] 1. High strength: Since the entire structure of the integrally forged hanger body 10 is continuous and there are no welding points, it has higher overall strength and durability.

[0087] 2. Good stability: The continuous flow of metal during forging can eliminate internal holes and cracks, thereby improving the stability and reliability of the hanger body 10.

[0088] 3. Light weight: Since the forging process can optimize the material distribution and remove excess material, the integrally forged hanger body 10 is usually lighter than cast or welded products.

[0089] 4. High precision: Higher dimensional precision can be achieved during forging, reducing the need for subsequent processing and improving production efficiency.

[0090] 5. Corrosion resistance: The tight structure of the metal during forging helps to improve the corrosion resistance of the hanger body 10.

[0091] 6. High production efficiency: Integral forging can reduce the steps of assembly and welding, thereby improving production efficiency.

[0092] 7. Low maintenance cost: Due to the high reliability and durability of the forged hanger body 10, its maintenance cost is relatively low.

[0093] 8. Wide range of applications: The integrally forged hanger body 10 can be widely applied to various fields such as heavy machinery, engineering equipment, transportation, etc., especially in applications that need to bear high loads and high impacts.

[0094] In the bogie frame of a rail transit vehicle, the integrally forged hanger body 10 can ensure the stable installation of key components such as the gearbox and motor, improving the safety and reliability of vehicle operation.

[0095] A rail vehicle bogie frame provided by the present application includes a crossbeam module 60. The crossbeam module 60 serves as the installation foundation for other components of the bogie and plays a role in transmitting traction force, braking force, lateral force, and vertical force during the traction operation of the locomotive. The crossbeam module 60 is arranged between two side beams, and an electric motor hanger, a gearbox hanger, and a traction rod seat are provided on the crossbeam module 60.

[0096] In addition, the rail vehicle bogie frame further includes a gearbox hanger mounted on the crossbeam module 60 and described as in the above specific embodiment. The gearbox hanger is used to support and fix the gearbox body 50.
