[0044] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0045] like Figure 1 As shown, a combined braking beam is provided according to a first aspect of the present disclosure, comprising: a strut 100; a support column 200, one end of which is connected to the strut 100 and is located between the two ends of the strut 100; an arc-shaped rod 300 connected between one end of the strut 100 and the other end of the support column 200, the arc-shaped rod 300 having a first segment 301 and a second segment 302 connected to each other, both the first segment 301 and the second segment 302 extending between the strut 100 and the support column 200, and the first segment 301 being located between the second segment 302 and the strut 100; and a connecting rod 400, one end of which is disposed at the connection between the first segment 301 and the second segment 302, and the other end of which is connected to the strut 100; wherein the extending direction of the first segment 301 intersects the extending direction of the second segment 302.

[0046] The combined brake beam provided in this embodiment includes a strut 100, a support column 200, an arc-shaped rod 300, and a connecting rod 400. The two ends of the support column 200 are respectively connected to the strut 100 and the arc-shaped rod 300, and the support column 200 is located between the two ends of the strut 100. The arc-shaped rod 300 is connected between the end of the support column 200 away from the strut 100 and the end of the strut 100. The arc-shaped rod 300 has a first segment 301 and a second segment 302 between its two ends. The first segment 301 is connected to the second segment 302, and the first segment 301 is located between the second segment 302 and the strut 100. The first segment 301 and the second segment 302... By extending in different directions, the bow-shaped rod 300 can extend in a roughly zigzag shape. One end of the connecting rod 400 is located at the connection between the first rod segment 301 and the second rod segment 302, and the other end is connected to the support rod 100. Based on the aforementioned configuration, the bending stiffness of the support rod 100 can be improved, thereby enhancing the overall structural stiffness of the combined brake beam. This is beneficial for improving the ability of the combined brake beam to resist deformation while maintaining a certain overall weight. It also improves the lightweighting level of the combined brake beam while ensuring its structural reliability, which is beneficial for reducing the overall weight and operating load of railway freight cars in practical applications.

[0047] Understandably, based on the aforementioned configuration, the combined brake beam can be roughly shaped like a folded truss. On the one hand, the aforementioned connecting rod 400 can increase the number of connection points between the two ends of the bow-shaped rod 300 and the two ends of the strut 100. Thus, with a fixed overall length of the bow-shaped rod 300 and the strut 100, the span between two adjacent connection points on the strut 100 and the span between two adjacent connection points on the bow-shaped rod 300 can be reduced. This is beneficial to improving the stress condition of the strut 100 and the bow-shaped rod 300, enhancing the structural stiffness of the strut 100, and improving the overall stiffness of the combined brake beam. On the other hand, the first segment 301, the second segment 302, and the connecting rod 400 can all be treated as two-force members mechanically. That is, in practical applications, the first segment 301, the second segment 302, and the connecting rod 400 mainly bear tensile and compressive stresses in their respective extension directions. This can prevent the bow-shaped rod 300 and the connecting rod 400 from bearing bending moments. Furthermore, based on the aforementioned connection relationship between the strut 100, the support column 200, the bow-shaped rod 300, and the connecting rod 400, the ability of the strut 100 to resist bending deformation can be improved in practical applications, the bending stiffness of the strut 100 can be enhanced, and the overall stiffness of the combined brake beam can be improved.

[0048] It is understandable that, in practical applications, the way the aforementioned bow-shaped rod 300 is connected between one end of the support rod 100 and the other end of the pillar 200 can be that both ends of the bow-shaped rod 300 in the extension direction are respectively connected to one end of the support rod 100 and the other end of the pillar 200. This is to reduce the redundant size of the bow-shaped rod 300 while establishing the connection between the bow-shaped rod 300, the pillar 200, and the support rod 100, and to avoid the bow-shaped rod 300 having an excessively long extension length and overall weight. The aforementioned extension direction of the bow-shaped rod 300 refers to the length direction of the bow-shaped rod 300.

[0049] It is understandable that, such as Figure 1 As shown, one end of the aforementioned support rod 100 refers to one end along its length. One end and the other end of the aforementioned support column 200 are the two ends along its length, respectively. The length direction of the aforementioned support rod 100 intersects with the length direction of the aforementioned support column 200. One end and the other end of the aforementioned connecting rod 400 are the two ends along its length, respectively.

[0050] It can be understood that the first rod segment 301 and the second rod segment 302 are both extended between the strut 100 and the support column 200, which means that the first rod segment 301 and the second rod segment 302 are both the part of the arcuate rod 300 between the end of the strut 100 connected to the arcuate rod 300 and the end of the support column 200 connected to the arcuate rod 300; in the case that the first rod segment 301 is between the second rod segment 302 and the strut 100, the second rod segment 302 is correspondingly between the first rod segment 301 and the support column 200; the first rod segment 301 and the second rod segment 302 are connected, which means that the end of the first rod segment 301 away from the strut 100 in the extension direction is connected to the end of the second rod segment 302 away from the support column 200 in the extension direction, and the extension direction of the first rod segment 301 and the extension direction of the second rod segment 302 respectively mean the length direction of the first rod segment 301 and the length direction of the second rod segment 302.

[0051] It can be understood that, as shown in Figure 1 , based on the aforementioned arrangement of the first rod segment 301 and the second rod segment 302, the extension direction of the first rod segment 301 and the extension direction of the second rod segment 302 are not coincident or parallel, that is, the included angle a between the extension direction of the first rod segment 301 and the extension direction of the second rod segment 302 is greater than 0° and less than 180°, and the aforementioned included angle a means the included angle of the first rod segment 301 and the second rod segment 302 on the side facing the strut 100.

[0052] It is understood that the bow-shaped rod 300 may also include a third rod segment extending between the first rod segment 301 and the strut 100. The extension direction of the third rod segment and the extension direction of the first rod segment 301 may intersect or be parallel. When the extension direction of the third rod segment intersects with the extension direction of the first rod segment 301, the angle between the extension directions of the third rod segment and the extension direction of the first rod segment 301 may be greater than 0° and less than 180°. The number of the aforementioned third rod segments may be greater than one. When the number of the aforementioned third rod segments is greater than one, multiple third rod segments are sequentially connected between the first rod segment 301 and the strut 100, and the extension directions of two adjacent third rod segments may also intersect or be parallel. Similarly, the bow-shaped rod 300 may also include a fourth rod extending between the second rod segment 302 and the support post 200. The extension direction of the fourth rod segment and the extension direction of the second rod segment 302 may intersect or be parallel. When the extension direction of the fourth rod segment and the extension direction of the second rod segment 302 intersect, the angle between the extension direction of the fourth rod segment and the extension direction of the second rod segment 302 may be greater than 0° and less than 180°. The number of the aforementioned fourth rod segments may be greater than one. When the number of the aforementioned fourth rod segments is greater than one, multiple fourth rod segments are sequentially connected between the second rod segment 302 and the support post 200, and the extension directions of two adjacent fourth rod segments may also intersect or be parallel.

[0053] It is understood that there can be two bow-shaped rods 300, with the two bow-shaped rods 300 respectively arranged at both ends of the support rod 100, and each bow-shaped rod 300 is connected to at least one of the aforementioned connecting rods 400. The aforementioned support column 200 can be located at the middle position in the extension direction of the support rod 100, and correspondingly, the two bow-shaped rods 300 can be arranged symmetrically about the support column 200.

[0054] It is understandable that the aforementioned first segment 301 and the aforementioned second segment 302 can be an integral structure.

[0055] Understandably, in practical applications, the extension lengths of strut 100, bow-shaped strut 300, first strut segment 301, and second strut segment 302, as well as the height of support column 200, can be optimized based on actual needs through simulation, experimentation, calculation, and other methods. Accordingly, the specific values ​​of the aforementioned extension lengths and heights can be selected in conjunction with actual needs, without making too many restrictions here.

[0056] like Figure 1 As shown, in some examples, along the extension direction of the strut 100, the support column 200 connected to one end of the strut 100, the connecting rod 400 connected to one end of the strut 100, and the bow-shaped rod 300 connected to one end of the strut 100 are arranged at intervals.

[0057] In the technical scheme, the relative positions of the one end of the strut 200 connected to the support rod 100, the one end of the connecting rod 400 connected to the support rod 100, and the one end of the arc-shaped rod 300 connected to the support rod 100 on the support rod 100 are constrained; based on the foregoing arrangement, the connection position between the support rod 100 and the strut 200, the connection position between the support rod 100 and the arc-shaped rod 300, and the connection position between the support rod 100 and the connecting rod 400 can be dispersed along the extension direction of the support rod 100, so that the bending deformation of the support rod 100 can be limited by the strut 200, the arc-shaped rod 300, and the connecting rod 400, and the bending stiffness of the support rod 100 is further improved, and the overall stiffness of the combined brake beam is improved.

[0058] It can be understood that the extension direction of the support rod 100 refers to the length direction of the support rod 100.

[0059] As shown in FIG. 1, Figure 1 In some examples, the combined brake beam further includes a brake shoe carrier 500 connected to one end of the support rod 100, the brake shoe carrier 500 has a mounting surface 501 for connecting brake shoes, and a spacing distance is formed between the connection between the support rod 100 and the arc-shaped rod 300 and the mounting surface 501 along the extension direction of the support rod 100; wherein the included angle α between the extension direction of the first rod segment 301 and the extension direction of the second rod segment 302 is negatively related to the foregoing spacing distance.

[0060] In the technical scheme, the combined brake beam can include the foregoing brake shoe carrier 500, and the foregoing included angle α is negatively related to the foregoing spacing distance; based on the foregoing arrangement, on the one hand, the combined brake beam can be conveniently connected to the brake shoes in actual application; on the other hand, in the case that the distance from the mounting surface 501 of the brake shoe carrier 500 to the connection between the support rod 100 and the arc-shaped rod 300 is relatively large, the distance from the brake shoes connected to the mounting surface 501 to the foregoing connection is also relatively large in actual application, and the support rod is easily subjected to a large bending moment in the use process, so that the extension direction difference between the first rod segment 301 and the second rod segment 302 can be increased by reducing the foregoing included angle α, the bending amplitude of the arc-shaped rod 300 is improved, the bending deformation of the support rod 100 is further limited by the arc-shaped rod 300 cooperating with the connecting rod 400 and the strut 200, the bending deformation limiting effect on the support rod 100 is enhanced, and the structural stiffness of the support rod 100 and the overall stiffness of the combined brake beam are improved.

[0061] It can be understood that the extension direction of the strut 200 refers to the length direction of the strut 200.

[0062] As shown in FIG. 1, Figure 1As shown, in some examples, the support column 200 is formed with a pin hole 201, which is located between the two ends of the support column 200 along the extension direction of the support column 200, and the maximum distance between the axis position of the pin hole 201 and the mounting surface 501 is greater than or equal to 10 mm and less than or equal to 40 mm.

[0063] In this technical solution, the relative position between the aforementioned pin hole 201 and the aforementioned mounting surface 501 is constrained; based on the aforementioned arrangement, the aforementioned maximum distance can be prevented from being too large, so that the action point of the gravity pressing force of the brake beam can be prevented from deviating away from the support rod 100, which is beneficial to improve the installation reliability and stability of the combined brake link in actual application, prevent the combined brake link from sinking on the side of the arch-shaped rod 300 and lifting on the side of the support rod 100 due to tilting, and further beneficial to ensure the position stability of the brake shoe and reduce the risk of eccentric wear of the brake shoe during use.

[0064] It can be understood that in actual application, the support column 200 can be used to connect a brake lever, the aforementioned pin hole 201 can be used to install a connecting pin, so that the support column 200 is connected to the aforementioned brake lever through the aforementioned connecting pin; the aforementioned mounting surface 501 can be substantially arc-shaped, and the maximum distance between the axis position of the aforementioned pin hole 201 and the mounting surface 501 refers to the distance between the axis position of the aforementioned pin hole 201 and the midline position of the arc-shaped surface (the position of the top of the arc-shaped surface) in the arc direction. In the conventional technology, the aforementioned maximum distance is about 53 mm.

[0065] It can be understood that in actual application, the aforementioned maximum distance can be adjusted by, but not limited to, adjusting the opening position of the aforementioned pin hole 201 on the support column 200 and / or adjusting the mounting position of the brake shoe carrier 500 on the support rod 100.

[0066] Exemplarily, the aforementioned maximum distance can be, but is not limited to, 15 mm, 25 mm, 32 mm, 35 mm, or 38 mm, etc., which can be selected according to actual needs, and will not be limited here.

[0067] As shown, Figure 1 In some feasible examples, the brake shoe carrier 500 has a support block 502, and the minimum distance between the support block 502 and the mounting surface 501 along the extension direction of the support column 200 is less than or equal to 30 mm.

[0068] In the technical scheme, the relative position between the support block 502 and the mounting surface 501 is constrained; based on the foregoing arrangement, the minimum distance can be prevented from being too large, so that the support point of the brake beam can be prevented from deviating toward the direction of the support rod 100, the installation reliability and stability of the combined brake beam in actual application can be improved, the phenomenon that the arch-shaped rod 300 sinks on the side and the support rod 100 lifts on the side due to inclination of the combined brake beam can be prevented, and then the position stability of the brake shoe can be ensured, and the risk of eccentric wear of the brake shoe in the use process can be reduced.

[0069] It can be understood that in actual application, the mounting surface 501 can be substantially arc-shaped, and the minimum distance between the support block 502 and the mounting surface 501 refers to the distance between the side of the support block 502 close to the arc-shaped surface and the midline position (the position of the top of the arc) of the arc-shaped surface in the arc direction.

[0070] Exemplarily, the minimum distance can be, but is not limited to, 25 mm, 20 mm, 15 mm, 12 mm or 10 mm, etc., and can be selected according to actual needs, which is not limited here.

[0071] It should be noted that in actual application, along the extension direction of the support column 200, the minimum distance between the support block 502 and the mounting surface 501 can be less than or equal to 30 mm, and the maximum distance between the axis position of the pin hole 201 and the mounting surface 501 can be greater than or equal to 10 mm and less than or equal to 40 mm.

[0072] As shown in FIG. 1, Figure 1 In some examples, the support rod 100 includes: a first plate member 110; a second plate member 120 arranged in parallel with the first plate member 110; and a first fastener 130 connecting the first plate member 110 and the second plate member 120.

[0073] In the technical scheme, the support rod 100 can include the first plate member 110, the second plate member and the first fastener 130; based on the foregoing arrangement, on the one hand, the main body of the support rod 100 can be composed of plate members arranged in parallel and at intervals, so that the volume of the solid structure of the support rod 100 can be further reduced, and compared with the support rod 100 made of pipe steel, channel steel or round steel, the light weight level of the support rod 100 can be further improved; on the other hand, in the arrangement direction of the first plate member 110 and the second plate member 120, the support rod 100 can be in a frame structure, which is beneficial to improve the bending stiffness of the support rod 100 in the arrangement direction of the first plate member 110 and the second plate member 120, and further enhance the overall stiffness of the combined brake beam.

[0074] It can be understood that, as Figure 1As shown, the parallel arrangement of the first plate member 110 and the second plate member 120 means that the length direction, the width direction and the thickness direction of the first plate member 110 are parallel to the length direction, the width direction and the thickness direction of the second plate member 120, respectively. The first plate member 110 and the second plate member 120 have the same shape, and the first plate member 110 and the second plate member 120 can be arranged in a spaced manner along the plate thickness direction.

[0075] It can be understood that the first fastener 130 can be, but is not limited to, a rivet or a screw. In the case of small-batch production, the first plate member 110 and the second plate member 120 can be laser cut and formed, and in the case of mass production, the first plate member 110 and the second plate member 120 can be stamped and formed, thereby reducing the difficulty of forming and assembling the support rod 100 in actual application. In the case where the first fastener 130 is a rivet, the first fastener 130 can be installed based on the rivet technology, thereby further enhancing the connection strength and reliability between the first fastener 130 and the first plate member 110 and the second plate member 120.

[0076] It can be understood that the first plate member 110 and the second plate member 120 can each be made of a steel strip. The shape and size of the steel strip used to make the first plate member 110 and the second plate member 120 can be optimized according to actual needs. Compared with the way of making the support rod 100 by using profiled steel, the steel strip can be more convenient to realize the equal strength design of the variable cross-section of the support rod 100, and can be more convenient to realize the diversification of the specifications of the combined brake beam, thereby adapting to different bogie use requirements.

[0077] As shown in FIG. 3, Figure 1 In some examples, the arcuate rod 300 includes a third plate member 310, a fourth plate member 320 arranged in parallel with the third plate member 310, and a second fastener 330 connecting the third plate member 310 and the fourth plate member 320.

[0078] In this technical solution, the arcuate rod 300 can include the third plate member 310, the fourth plate member and the second fastener 330. Based on the foregoing arrangement, on the one hand, the main body of the arcuate rod 300 can be composed of plate members arranged in parallel and in a spaced manner, thereby further reducing the volume of the solid structure of the arcuate rod 300, and compared with the arcuate rod 300 made of pipe steel, channel steel or round steel, the arcuate rod 300 can further improve the lightweight level. On the other hand, in the arrangement direction of the third plate member 310 and the fourth plate member 320, the arcuate rod 300 can have a frame structure, which is conducive to improving the bending stiffness of the arcuate rod 300 in the arrangement direction of the third plate member 310 and the fourth plate member 320, and further enhancing the overall stiffness of the combined brake beam.

[0079] It can be understood that, as shown in FIG. 3, Figure 1As shown, the parallel arrangement of the third plate member 310 and the fourth plate member 320 means that the length direction, the width direction and the thickness direction of the third plate member 310 are parallel to the length direction, the width direction and the thickness direction of the fourth plate member 320, respectively. The third plate member 310 and the fourth plate member 320 have the same shape, and the third plate member 310 and the fourth plate member 320 can be arranged in a spaced apart manner along the plate thickness direction.

[0080] It can be understood that the second fastener 330 can be, but is not limited to, a rivet or a screw. In the case of small-batch production, the third plate member 310 and the fourth plate member 320 can be laser cut and formed, and in the case of mass production, the third plate member 310 and the fourth plate member 320 can be stamped and formed, thereby reducing the difficulty of forming and assembling the support rod 100 in actual application. In the case where the second fastener 330 is a rivet, the second fastener 330 can be installed based on the rivet technology, thereby further enhancing the connection strength and reliability between the first fastener 130 and the first plate member 110 and the second plate member 120.

[0081] It can be understood that the third plate member 310 and the fourth plate member 320 can each be made of a steel strip. The shape and size of the steel strip used to make the third plate member 310 and the fourth plate member 320 can be optimized according to actual needs, and compared with the way of using profiled steel to make the arcuate rod 300, the arcuate rod 300 can be more easily realized to have a variable cross-section and equal strength design, and the combined brake beam can be more easily realized to have a variety of specifications and to adapt to different bogie usage requirements.

[0082] It can be understood that, as shown in Figure 1 The third plate member 310 and the fourth plate member 320 each have the first rod segment 301 and the second rod segment 302.

[0083] As shown in Figure 1 In some feasible examples, the connection between the connecting rod 400 and the support rod 100 is located between one end of the support rod 100 and the support column 200.

[0084] As shown in Figure 1 Exemplarily, in the case where the support rod 100 includes the first plate member 110 and the second plate member 120, and the arcuate rod 300 includes the third plate member 310 and the fourth plate member 320, the connecting rod 400 can include a fifth plate member 410 and a sixth plate member 420, and the fifth plate member 410 and the sixth plate member 420 are arranged in parallel. The two ends of the fifth plate member 410 are connected to the first plate member 110 and the third plate member 310, respectively, and the two ends of the sixth plate member 420 are connected to the second plate member 120 and the fourth plate member 320, respectively.

[0085] As shown in Figure 1As shown, in some examples, an included angle a between an extension direction of the first rod segment 301 and an extension direction of the second rod segment 302 is greater than or equal to 160° and less than 180°.

[0086] In this technical solution, the aforementioned included angle a is greater than or equal to 160° and less than 180°; based on the aforementioned arrangement, it can be avoided that the included angle a is too small, so that the overall extension length of the arc-shaped rod 300 caused by the too large bending amplitude can be avoided, which is beneficial to guarantee the lightweight level of the combined brake beam.

[0087] It can be understood that, in actual application, the aforementioned included angle a can be optimized and designed through simulation, test, calculation and the like based on actual requirements, and accordingly, the specific value of the aforementioned included angle a can be selected in combination with actual requirements, which is not limited too much here.

[0088] In some examples, the brace rod 100 is riveted to the support column 200; and / or the brace rod 100 is riveted to the arc-shaped rod 300; and / or the arc-shaped rod 300 is riveted to the support column 200.

[0089] In this technical solution, the brace rod 100 and the support column 200 can be connected through riveting; based on the aforementioned arrangement, the connection difficulty between the brace rod 100 and the support column 200 can be reduced, which is further beneficial to reduce the manufacturing process complexity and manufacturing cost of the combined brake beam.

[0090] In this technical solution, the brace rod 100 and the arc-shaped rod 300 can be connected through riveting; based on the aforementioned arrangement, the connection difficulty between the brace rod 100 and the arc-shaped rod 300 can be reduced, which is further beneficial to reduce the manufacturing process complexity and manufacturing cost of the combined brake beam.

[0091] In this technical solution, the support column 200 and the arc-shaped rod 300 can be connected through riveting; based on the aforementioned arrangement, the connection difficulty between the support column 200 and the arc-shaped rod 300 can be reduced, which is further beneficial to reduce the manufacturing process complexity and manufacturing cost of the combined brake beam.

[0092] It can be understood that the brace rod 100, the support column 200 and the arc-shaped rod 300 are connected two by two, and one or more or all of the connection points involved can adopt riveting.

[0093] Exemplarily, the support rod 100 is riveted to the support post 200, the support rod 100 is riveted to the arc-shaped rod 300, and the arc-shaped rod 300 is riveted to the support post 200. In the case that the combined brake beam comprises the aforementioned shoe plate 500, the shoe plate 500 is riveted to the aforementioned support rod 100. In the case that the combined brake beam comprises the aforementioned connecting rod 400, the two ends of the connecting rod 400 are respectively riveted to the aforementioned support rod 100 and the aforementioned arc-shaped rod 300. Therefore, the riveting connection is adopted between the various components of the combined brake beam, which can greatly reduce the manufacturing process complexity and manufacturing cost of the combined brake beam. The aforementioned riveting can be achieved based on the pull riveting technology, so as to further reduce the process difficulty and complexity of the riveting and ensure the connection reliability.

[0094] It can be understood that, since the arc-shaped rod 300 is connected to the one end of the support rod 100 and the position of the shoe plate 500 is relatively close on the support rod 100, when the arc-shaped rod 300 and the shoe plate 500 are riveted to the support rod 100, the corresponding rivets can simultaneously pass through the support rod 100, the arc-shaped rod 300 and the shoe plate 500, that is, the rivets used for riveting the arc-shaped rod 300 to the support rod 100 and the rivets used for riveting the shoe plate 500 to the support rod 100 can be the same, so as to reduce the openings on the support rod 100 and further ensure the structural reliability of the support rod 100.

[0095] In some examples, the support rod 100 and the arc-shaped rod 300 are both made of weathering steel.

[0096] In the technical solution, the aforementioned support rod 100 and the arc-shaped rod 300 can be both made of weathering steel. Based on the aforementioned setting, the corrosion resistance of the support rod 100 and the arc-shaped rod 300 can be improved, so as to be beneficial to prolong the service life of the support rod 100 and the arc-shaped rod 300 and provide protection for the overall strength and rigidity of the combined brake beam.

[0097] Exemplarily, the aforementioned support rod 100 and the arc-shaped rod 300 can be both made of Q450NQR1.
