[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model provides a single-pull-rod hinged traction device, which optimizes the traditional double traction rod 30 structure into a single traction rod 30, significantly reducing the number of parts, simplifying the structure, and making installation and maintenance convenient.

[0031] Please refer to this as well. Figures 1 to 5 The single-rod articulated traction device provided by this utility model includes a first traction seat 10, a second traction seat 20, and a traction rod 30.

[0032] The first traction seat 10 is installed on the first car body 40, and the second traction seat 20 is installed on the second car body 50. The first car body 40 and the second car body 50 are supported by the bogie.

[0033] One end of the traction rod 30 is connected to the bogie frame 60, and the other end of the traction rod 30 is connected to the second traction seat 20.

[0034] The first traction seat 10 and the second traction seat 20 are connected by a hinge 70 to hinge the first vehicle body 40 and the second vehicle body 50.

[0035] The single-rod articulated traction device provided by this utility model has a first traction seat 10 and a second traction seat 20 respectively installed on a first car body 40 and a second car body 50. The first traction seat 10 and the second traction seat 20 are connected by a hinge 70 to realize the articulation of the first car body 40 and the second car body 50. The two ends of the traction rod 30 are respectively connected to the bogie frame 60 and the second traction seat 20, thereby connecting the first car body 40 and the second car body 50 to a bogie and realizing the transmission of traction and braking force between the bogie and the car body.

[0036] This design optimizes the traditional double traction rod 30 structure into a single traction rod 30, significantly reducing the number of components and simplifying the structure. The connection is achieved through the cooperation of the hinge 70 and the traction rod 30, making installation convenient and reducing assembly complexity. The simplified structure reduces potential failure points, extends the service life of the device, and lowers maintenance costs.

[0037] Please refer to this as well. Figure 1 , Figure 2 and Figure 4 The first traction seat 10 is installed at the end of the first vehicle body 40, located at the end of the first vehicle body 40 and the second vehicle body 50 that are close to each other. The first traction seat 10 includes a first fixing part 11 and a first mounting part 12. The first fixing part 11 is generally plate-shaped, and the extension direction of the first fixing part 11 is perpendicular to the extension direction of the first mounting part 12. The first fixing part 11 and the first mounting part 12 are smoothly transitioned, and the first mounting part 12 is located in the middle of the first fixing part 11.

[0038] The smooth transition between the first fixing part 11 and the first mounting part 12 can reduce stress concentration. By making the connection between the first fixing part 11 and the first mounting part 12 smoother, stress concentration can be reduced.

[0039] Please refer to this as well. Figure 1 , Figure 2 and Figure 4 The first fixing part 11 has a plurality of first threaded holes 111 along its edge, and the first mounting part 12 is fixed to the first vehicle body 40 by bolts. The plurality of first threaded holes 111 are symmetrically distributed on both sides of the first mounting part 12. When the first traction seat 10 is installed at the end of the first vehicle body 40, it can be connected to the first vehicle body 40 by passing bolts through the first threaded holes 111 on the first fixing part 11, which is not only reliable but also convenient for installation.

[0040] Please refer to this as well. Figure 1 , Figure 2 and Figure 4 The first mounting portion 12 is provided with a first mounting hole 121, and the hinge member 70 is mounted in the first mounting hole 121. The hinge member 70 is rotatably disposed in the first mounting portion 12. In this embodiment, the hinge member 70 may be a center pin.

[0041] Please refer to this as well. Figure 1 , Figure 2 and Figure 5 The second traction seat 20 is installed at the end of the second vehicle body 50, located at the end of the first vehicle body 40 and the second vehicle body 50 that are close to each other. The second traction seat 20 includes a second fixing part 21 and a second mounting part 22. The second fixing part 21 is generally plate-shaped and has a plurality of second threaded holes 211 along the circumference. The second fixing part 21 is fixed to the second vehicle body 50 by bolts.

[0042] Multiple second threaded holes 211 are provided near the edge of the second fixing part 21. When the second traction seat 20 is installed at the end of the second vehicle body 50, it can be connected to the second vehicle body 50 by passing a bolt through the second threaded holes 211 on the second fixing part 21. This not only ensures a reliable connection but also facilitates installation.

[0043] Please refer to this as well. Figure 1 , Figure 2 and Figure 5 The second mounting portion 22 has a U-shaped groove 221 on one side, and the hinge 70 is at least partially located in the U-shaped groove 221. The hinge 70 is rotatably disposed in the U-shaped groove 221. The hinge 70 is connected by cooperating with the first mounting hole 121 on the first mounting portion 12 of the first traction seat 10 and the U-shaped groove 221 of the second mounting portion 22 of the second traction seat 20, which makes installation convenient and assembly easy.

[0044] Please refer to this as well. Figure 1 , Figure 2 and Figure 5 The second mounting part 22 is provided with two mounting posts 222 at intervals on the side opposite to the U-shaped groove 221, and the mounting posts 222 are provided with through holes.

[0045] Please refer to this as well. Figures 1 to 3 The two ends of the traction rod 30 are fixed with hinge pins 31, which are perpendicular to the traction rod 30. The two ends of the hinge pins 31 are provided with third threaded holes 311. One end of the traction rod 30 is located between two mounting posts 222. The hinge pins 31 and the mounting posts 222 are connected by bolts and nuts.

[0046] When the traction rod 30 is connected to the second traction seat 20, one end of the traction rod 30 is accommodated between the two mounting posts 222 of the second mounting part 22. The bolt passes through the third threaded hole 311 on the hinge pin 31 and the through hole on the mounting post 222, and is locked in place by a nut. Both ends of the hinge pin 31 are connected to the two mounting posts 222 respectively by bolts and nuts, ensuring reliable connection and facilitating installation while maintaining structural stability.

[0047] Please refer to this as well. Figures 1 to 2 The frame 60 of the traction frame is provided with two spaced mounting blocks 61. The other end of the traction rod 30 is located between the two mounting blocks 61. The hinge pin 31 at this end of the traction rod 30 is connected to the mounting block 61 by bolts and nuts.

[0048] When the traction rod 30 is connected to the frame 60 of the traction frame, the other end of the traction rod 30 is accommodated between two mounting blocks 61. Bolts are used to pass through the hinge pin 31 and the mounting block 61, and are locked and fixed by nuts. Both ends of the hinge pin 31 are connected to the two mounting blocks 61 by bolts and nuts respectively. The connection is reliable and facilitates installation while ensuring structural stability.

[0049] With this configuration, the connection is achieved by the hinge pins 31 at both ends of the traction rod 30 cooperating with the second traction seat 20 and the frame 60 of the traction frame, which reduces assembly complexity and makes installation convenient.

[0050] The single-rod articulated traction device provided by this utility model has a first traction seat 10 and a second traction seat 20 respectively installed at the ends of the first car body 40 and the second car body 50. The first traction seat 10 and the second traction seat 20 are connected by a hinge 70 to realize the articulation of the first car body 40 and the second car body 50. The two ends of the traction rod 30 are respectively connected to the bogie frame 60 and the second traction seat 20, thereby connecting the first car body 40 and the second car body 50 to a bogie and realizing the transmission of traction and braking force between the bogie and the car body.

[0051] By optimizing the traditional double traction rod 30 structure into a single traction rod 30, the number of components is significantly reduced, which is beneficial to structural simplification. The connection is achieved through the cooperation of the hinge 70 with the first traction seat 10 and the second traction seat 20, and the cooperation of the hinge pins 31 at both ends of the traction rod 30 with the second traction seat 20 and the frame 60 of the traction frame. This makes installation convenient and reduces assembly complexity. The simplified structure reduces failure points, increases the service life of the device, and reduces maintenance costs.
