[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1-3 As shown;

[0035] A method for suspending a traction motor 1 is invented, comprising:

[0036] The traction motor 1 is hung on the frame crossbeam 2 in a suspended form, and the connection point S of the traction motor 1 and the frame crossbeam 2 are rigidly connected, wherein the connection point S of the traction motor 1 is arranged at the upper and lower positions on the same side of the traction motor 1, and a removable vertical stop plate 5 is provided at the connection point S below the traction motor 1 to support the traction motor 1 while connecting the connection point S to the frame crossbeam 2 in a hooked form.

[0037] A horizontally extending anti-slip stop 4 is installed on the side of the traction motor 1 away from the connection point S. The axle-side anti-slip stop 4 is bolted to the traction motor 1. A vertical stop plate 5 is inserted into the hanger 3 of the frame crossbeam 2. During disassembly, the inserted vertical stop plate 5 is removed and the hook connection is unlocked, preventing the bogie from separating from the vehicle body. The traction motor 1 can be removed from the bottom of the bogie frame, greatly reducing the maintenance time of the traction motor 1 and improving efficiency.

[0038] See also Figure 1 、 4 As shown:

[0039] A traction motor suspension frame is invented to implement the above-mentioned traction motor suspension method. A frame crossbeam 2 is provided in the middle of the frame body. A hanger 3 is fixedly connected to the frame crossbeam 2 on the axle side. An upper connecting seat 301 and a lower connecting seat 302 are fixedly connected to the mounting surface of the hanger 3, which are hooked with the connection point S. A slot 7 formed at the top of the lower connecting seat 302 is inserted with a vertical stop plate 5 that can move laterally. The upper portion of the vertical stop plate 5 abuts against a support block 101 provided on the connection point S of the traction motor 1.

[0040] During assembly, after the vertical stop plate 5 is inserted, the vertical stop plate 5 is restricted in the slot 7 and can only move laterally. The support block 101 contacts the vertical stop plate 5 to prevent the traction motor 1 from moving downward. The upper connecting seat 301 and the lower connecting seat 302 are hooked and connected to the connection point S of the traction motor 1 to prevent the traction motor 1 from moving laterally. Then, the vertical stop plate 5 is used to lock the traction motor 1 on the hanger 3. While the vertical stop plate 5 supports the traction motor 1, the connection point S is connected and locked to the frame crossbeam 2 in the form of a hook. The vertical stop plate 5 passes through the two hangers 3 at the same time, that is, the two hangers 3 configured for the same traction motor 1 use one vertical stop plate 5.

[0041] See also Figure 5 、7 As shown:

[0042] Preferably, an L-shaped gripping portion 303 is formed on the upper connecting seat 301 and the lower connecting seat 302 away from the mounting surface. A matching portion 102 having the same structure as the gripping portion 303 is formed at the connection point S of the traction motor 1. The gripping portion 303 is integrally formed with the upper connecting seat 301 and the lower connecting seat 302. The gripping portion 303 has a horizontal section and a vertical section. The angle between the vertical section and the horizontal section is 90°, so that the cross section forms an L-shaped structure. A matching portion 102 is integrally formed on the outer side of the base at the upper and lower connection points S of the traction motor 1. The matching portion 102 has the same structure as the gripping portion 303. During assembly, the two portions are hooked together to limit the lateral displacement of the traction motor 1. During disassembly, the two portions are staggered by pulling up and down, so that the hook can successfully disassemble the traction motor 1.

[0043] See also Figure 3 、 5 As shown:

[0044] Preferably, the lower connecting seat 302 is located above the hook grip portion 303 and is provided with a limiting boss 304 parallel to the upper surface of the hook grip portion 303. After the traction motor 1 is assembled, the limiting boss 304, the hook grip portion 303, the base of the traction motor 1, and the support block 101 on the base together form a slot 7. When the vertical stop plate 5 is inserted, the upper surface of the hook grip 303 is used to prevent the vertical stop plate 5 from moving downward, the limiting boss 304 is raised and forms a groove structure with the hook grip 303 on the lower connecting seat 302, the limiting boss 304 is used to prevent the vertical stop plate 5 from moving upward, and the side wall of the traction motor 1 base and the support block 101 on the base are combined with the groove structure to limit the vertical stop plate 5 to only move horizontally, so that the vertical stop plate 5 supports the traction motor 1 while the matching part 102 of the connection point S of the traction motor 1 maintains a hook connection posture with the upper connecting seat 301 and the hook grip 303 of the lower connecting seat 302, thereby stably suspending the traction motor 1.

[0045] See also Figure 4 As shown:

[0046] Preferably, the upper connecting seat 301 and the lower connecting seat 302 are fastened to the connection point S of the traction motor 1 by bolting, wherein the upper connecting seat 301 and the lower connecting seat 302, as well as the hanger 3, are all provided with mounting holes, and a threaded hole corresponding to the mounting hole of the lower connecting seat 302 is provided at the lower connecting point S of the base of the traction motor 1. During assembly, the bolt 9 passes through the hanger 3, the mounting holes of the lower connecting seat 302, and is threadedly connected to the threaded hole of the base of the traction motor 1 to fasten the lower connecting seat 302 and the base. A light hole corresponding to the mounting hole of the upper connecting seat 301 is provided at the upper connecting point S of the base of the traction motor 1. During assembly, the bolt 10 passes through the light hole of the base of the traction motor 1, the lower connecting seat 302, and the mounting holes of the hanger 3 in sequence, and is then threadedly connected to the special-shaped nut 6;

[0047] See also Figure 4a 、 5 , 6 as shown:

[0048] Preferably, it also includes a special-shaped nut 6, a limiting groove 305 is provided at the top of the hanger 3, and a clamping groove 306 with a width adapted to the width of the special-shaped nut 6 is processed on the top of the limiting groove 305. A hook portion 601 is formed at one end of the special-shaped nut 6 to cooperate with the clamping groove 306, and the other end extends along the length direction of the hanger 3. During assembly, the special-shaped nut 6 is inserted into the limiting groove 305 of the hanger 3 to ensure that the special-shaped nut 6 is concentric with the mounting hole of the hanger 3. The hook portion 601 at the top of the special-shaped nut 6 is engaged in the clamping groove 306, and the clamping groove 306 blocks the special-shaped nut 6 from rotating and displacing, avoiding the need for other disassembly tools during disassembly;

[0049] See also Figure 3 、 4 As shown:

[0050] Preferably, the vertical stop plate 5 is provided with connecting members 8 at both ends, and is fixedly connected to the lower connecting seat 302 through the connecting members 8, wherein the connecting members 8 are bolts. Of course, other forms of connecting members 8 that can be easily disassembled to connect the vertical stop plate 5 to the lower connecting seat 302, such as pins, can be used to prevent the vertical stop plate 5 from falling off laterally. In this embodiment, bolts are used as an example. Both ends of the vertical stop plate 5 and the lower connecting seat 302 are provided with mounting holes for mounting bolts, which are fastened by nuts after the bolts are installed.

[0051] See also Figure 1 、 5 As shown:

[0052] Preferably, one side of the hanger 3 is fixedly connected to the frame crossbeam 2 by a welding process, and the mounting surface formed on the other side is parallel to the vertical plane. The upper connecting seat 301 and the lower connecting seat 302 are both connected to the connection point S of the traction motor 1 in the form of a hook in the horizontal direction. In other words, when the mounting surface of the hanger 3 is a vertical plane, the hanger 3 is welded with an upper connecting seat 301 and a lower connecting seat 302 on the mounting surface, so that the upper connecting seat 301 and the lower connecting seat 302 are connected to the connection point S of the traction motor 1 in the horizontal direction by a hook, thereby limiting the lateral displacement of the traction motor 1. When disassembling, after removing the vertical stop plate 5, the traction motor 1 is vertically displaced along the mounting surface so that the connection point S and the upper connecting seat 301 and the lower connecting seat 302 are hooked, and the motor is removed for successful disassembly.

[0053] In the above technical solution, the traction motor frame suspension structure provided by the present invention is suspended on the frame crossbeam 2 and is rigidly connected to the frame through four upper and lower bolts. The anti-falling function of the traction motor 1 is that the anti-falling stopper 4 is fastened by two bolts on the axle side, and a vertical stop plate 5 is provided on the side of the frame crossbeam 2. The vertical stop plate 5 is limited by the slot 7 and is fastened to the lower connecting seat 302 by bolts. The hanging seat 3 is processed with a card slot 306, and a special-shaped nut 6 is placed on the card slot 306 to play an anti-rotation function. The two upper bolts 9 are fastened by the special-shaped nut 6;

[0054] When disassembling the traction motor 1, first loosen the axle-side anti-slip stop 4 fastening bolts and remove the anti-slip stop 4. Next, loosen the two bolts 9 connecting the upper part to the hanger 3 and the connecting pieces 8 at both ends of the vertical stop plate 5 from the axle side. Remove the vertical stop plate 5 laterally from the side and remove the two bolts 10 connecting the lower part of the hanger 3. The engaging portion 101 and the hooking portion 303 are staggered to support the hook, so that the bogie and the car body are not separated, and the traction motor 1 can be removed from the bottom of the bogie.

[0055] A bogie is invented, which includes: the above-mentioned traction motor frame suspension frame, the frame body is located between two frame crossbeams 2 and connected to the longitudinal beam, and a traction motor 1 is equipped with two hangers 3, wherein one hanger 3 is fixedly connected to the end of the longitudinal beam in the form of butt joint by a welding process. The butt joint method optimizes the structure and reduces local stress. Traction motors 1 are installed on both sides of the frame body.
