Description

Technical Field

[0001] This utility model relates to the field of suspension bracket assembly technology, and in particular to a suspension bracket assembly for a railway vehicle bogie. Background Technology

[0002] Rail vehicles are becoming increasingly common in various cities. Among them, the rail vehicle bogie is a relatively important component. The various parameters of the bogie directly determine the stability and ride comfort of the vehicle. In order to connect the bogie to the rail vehicle, a jack is required.

[0003] A search revealed that CN214164995U discloses a bogie suspension assembly, including a base with four casters on its underside. A main support device is located outside the base, comprising a main support frame. An upper cover is fixedly connected to the top of the main support frame, and an upper pressure plate is fixedly connected to the lower front part of the upper cover. A slot is formed on the front of the main support frame, and a motor body is fixedly connected to the inner bottom surface of the main support frame. Two partitions are fixedly connected to the top of the motor body. A lower clamping device is located outside the base. This bogie suspension assembly, through the two partitions, prevents the T-plate from directly contacting the motor body, thus preventing wear. The upward or downward movement of the T-plate causes the main clamping box to move upward or downward, which in turn drives the bogie to rise and fall. By using the main clamping box to raise and lower the bogie, the practicality of the device is improved.

[0004] When this technical solution is in use, the position of the side clamping plate is adjusted by rotating the knob and driving the rectangular gear through the gear to adapt to different types of bogies. When this clamping method is used for clamping and fixing, the side clamping plate is prone to squeezing the gear and rectangular gear under the stress of the bogie shaking inside it. The gear and rectangular gear will deflect and cause the side clamping plate to shift, affecting the clamping effect. It is also easy for the gear and rectangular gear to be squeezed down, affecting their meshing effect and affecting their service life.

[0005] Therefore, we propose a bogie mounting assembly for rail vehicles. Utility Model Content

[0006] The present invention mainly solves the technical problems of the above-mentioned prior art where the extrusion and deflection of gears and rectangular gears causes the side clamping plate to shift, affecting the clamping effect, and the damage to gears and rectangular gears caused by extrusion affects their service life.

[0029] Example 1: A bogie hanger assembly for rail vehicles, such as Figure 1 , Figure 2 and Figure 3 As shown, including

[0030] Base 1, on which are mounted a main support 2, an upper cover 3, a T-shaped plate 4, a connecting rod 6, a side clamping plate 7, a motor body 8, and a first threaded rod 9. (The base 1 has wheels at its four bottom corners for movement. The main support 2 is fixedly connected to one side of the top of the base 1 and has a T-shaped groove. The T-shaped plate 4 is slidably connected to the inner wall of the T-shaped groove. The upper cover 3 is fixedly connected to the top of the main support 2 and has an upper pressure plate at its bottom for pressing. The motor body 8 is fixedly connected to the top of the base 1 via a motor frame. The first threaded rod 9 is located at the output end of the motor body 8. The T-shaped plate 4...) The inner part has a threaded hole, the first threaded rod 9 is threaded to the inner wall of the threaded hole, the connecting rod 6 is set at the top two ends of the T-shaped plate 4, and the side clamping plate 7 is set on the opposite wall surface of the two connecting rods 6. (The part in parentheses is the prior art.) When it is needed for use, the base 1 is pushed and the base 1 is moved to the appropriate position by the four wheels below. At this time, the motor body 8 is started and drives the first threaded rod 9 to rotate, which in turn drives the T-shaped plate 4 threaded to it to move vertically in the T-shaped groove. It is pressed and fixed by the T-shaped plate 4 and the upper pressure plate at the bottom of the top cover 3, and then clamped and fixed by the side clamping plates 7 on both sides.

[0031] An adjustment assembly is installed inside the T-shaped plate 4 to adjust the position of the connecting rod 6 and the side clamping plate 7. The adjustment assembly includes an adjustment frame 10, a second threaded rod 11, a transmission shaft 13, and an adjustment seat 15.

[0032] A locking assembly is provided inside the T-shaped plate 4 to lock the positions of the connecting rod 6 and the adjusting frame 10. The locking assembly includes a pressing block 18, an adjusting plate 20, and a locking rod 24.

[0033] like Figure 4 and Figure 6As shown, the T-shaped plate 4 has a first sliding groove at both ends. The adjusting frame 10 is slidably connected to the inner wall of the first sliding groove in a frame shape. The connecting rod 6 is fixedly connected to the outer wall of one side of the adjusting frame 10. The T-shaped plate 4 has a rotating groove in the middle of its inner wall. An adjusting groove is provided on the outside of the rotating groove. The adjusting seat 15 is rotatably connected to the inner wall of the rotating groove. The adjusting seat 15 is fixedly connected to the outer wall of the first bevel gear 16. The first bevel gear 16 is located in the adjusting groove. The adjusting groove has a through rotating hole near the first sliding groove. The second threaded rod 11 is rotatably connected to the inner wall of the rotating hole. The second threaded rod 11 is axially fixedly connected to a second bevel gear 17 that meshes with the first bevel gear 16 at one end near the adjusting seat 15. The second threaded rod 11 is threadedly connected to the inner wall of the adjusting frame 10.

[0034] The inner wall of the T-shaped plate 4 has a through hole that passes through the inner wall of the adjusting seat 15. A drive shaft 13 is installed at the through hole. A knob 5 for adjustment is fixedly connected to one end of the drive shaft 13 in an axial position. A first return spring 14 is installed at one end of the through hole. The other end of the first return spring 14 is in contact with the drive shaft 13. A plurality of insert rods 22 arranged in a circle are installed on the drive shaft 13. A through slot 23 is opened in the adjusting seat 15. The insert rods 22 are adapted to the slot 23.

[0035] When the position of the connecting rod 6 needs to be adjusted, the knob 5 is pressed, which causes the transmission shaft 13 to press against the first return spring 14. The first return spring 14 resets the transmission shaft 13 through its elasticity. The movement of the transmission shaft 13 can move the insertion rod 22 on it. The insertion rod 22 can then be inserted into the slot 23 on the adjusting seat 15. At this time, the knob 5 is rotated, which can drive the adjusting seat 15 to rotate through the transmission shaft 13 and the insertion rod 22. The adjusting seat 15 can then drive the second bevel gear 17 meshing with it to rotate through the first bevel gear 16. The second bevel gear 17 drives the second threaded rod 11 to rotate, which can drive the adjusting frame 10 threadedly connected to it to slide in the first sliding groove, thereby driving the connecting rod 6 to move and adjust synchronously.

[0036] like Figure 5 and Figure 7 As shown, the inner walls of the T-shaped plate 4 are provided with second sliding grooves on both sides. The extrusion block 18 is slidably connected to the inner wall of the second sliding groove and rotatably connected to the outer wall of the transmission shaft 13. Both ends of the extrusion block 18 are inclined.

[0037] The T-shaped plate 4 has a third sliding groove at both the top and bottom. The adjusting plate 20 is slidably connected to the inner wall of the third sliding groove. A second reset spring 19 is provided on the wall surface of the adjusting plate 20 opposite to the third sliding groove. The third sliding groove is connected to the second sliding groove. A pressure block 21 is provided on the side of the adjusting plate 20 near the extrusion block 18. The pressure block 21 is inclined and in contact with the extrusion block 18.

[0038] When the drive shaft 13 moves, it can drive the pressing block 18 to slide in the second sliding groove. The movement of the pressing block 18 can press the pressure block 21 at the bottom of the adjusting plate 20, causing the adjusting plate 20 to slide in the third sliding groove, and then causing the adjusting plate 20 to move away from the adjusting frame 10.

[0039] like Figure 4 and Figure 7 As shown, multiple locking holes 12 arranged linearly are provided at both ends of the adjustment frame 10. The locking rod 24 is located at the four corners of the adjustment plate 20 near the adjustment frame 10, and the locking rod 24 is adapted to the locking hole 12.

[0040] When the adjusting plate 20 moves, the locking rod 24 can be moved out of the locking hole 12 to release the locking of the adjusting frame 10. After the adjustment is completed, the transmission shaft 13 is driven back to its original position by the elastic force of the first return spring 14, and the adjusting plate 20 is driven back to its original position by the elastic force of the second return spring 19. At this time, the locking rod 24 can be inserted into the locking hole 12 to lock the adjusting frame 10, and then lock the positions of the connecting rod 6 and the side clamp 7.

[0041] In summary, by adjusting and locking the connecting rod 6, the position can be adjusted by pressing and rotating the knob 5. The locking rod 24 is then inserted into the locking hole 12 to lock the connecting rod 6. This locking rod 24 can bear the stress on the connecting rod 6 and the side clamping plate 7, preventing the stress from the shaking of the clamped object from squeezing the connecting rod 6 and the side clamping plate 7. This would prevent the first bevel gear 16 and the second bevel gear 17 from being squeezed and deflected, causing the side clamping plate 7 to shift and affecting the clamping effect. Furthermore, it can prevent the first bevel gear 16 and the second bevel gear 17 from being squeezed and damaged, thus affecting their service life.

[0042] Example 2: Based on Example 1, with reference to Figure 8 The adjustment plate 20 is fixedly connected to four corners of a fixed box 25. The inner wall of the fixed box 25 is slidably connected to a limit slider 26. The limit slider 26 and the inner wall of the fixed box 25 are fixedly connected to two ends of a third return spring 27. The locking rod 24 is fixedly connected to the outer wall of one side of the limit slider 26. The tail end of the locking rod 24 is conical.

[0043] When the locking rod 24 moves to the locking hole 12 on the adjusting frame 10 for insertion, if the two become misaligned, the inner wall of the locking hole 12 can press the conical part on the locking rod 24, causing the locking rod 24 to move. By pressing the limiting slider 26 and the third return spring 27, the locking rod 24 is moved to the same axis as the locking hole 12, so that the locking rod 24 can be inserted into the locking hole 12 for locking.

[0044] By using the fixed box 25, the limiting slider 26 and the third return spring 27, when there is a misalignment between the locking rod 24 and the locking hole 12, the position of the locking rod 24 can be adjusted to be on the same axis as the locking hole 12 by the squeezing of the inner wall of the locking hole 12, so as to facilitate the insertion and locking and avoid the two being misaligned and unable to be inserted and locked.

[0045] The working principle of this utility model is as follows: When needed, push the base 1. The base 1 moves to a suitable position via the four wheels below. At this time, the motor body 8 starts and drives the first threaded rod 9 to rotate, which in turn drives the T-shaped plate 4 connected to it to move vertically in the T-groove. The T-shaped plate 4 and the upper pressure plate at the bottom of the top cover 3 are pressed and fixed. Then, press the knob 5, which drives the transmission shaft 13 to press the first return spring 14. The first return spring 14 resets the transmission shaft 13 through its elasticity. The movement of the transmission shaft 13 drives the insertion rod 22 on it to move. The insertion rod 22 can then be inserted into the slot 23 on the adjusting seat 15. At this time, turn the knob 5. The knob 5 drives the adjusting seat 15 to rotate via the transmission shaft 13 and the insertion rod 22. The adjusting seat 15 then drives the second bevel gear 17 meshing with it to rotate via the first bevel gear 16. 7. Rotating the second threaded rod 11 causes the adjusting frame 10 connected to it to slide in the first sliding groove, which in turn causes the connecting rod 6 to move and adjust synchronously. When the transmission shaft 13 moves, the pressing block 18 can slide in the second sliding groove. The pressing block 18 can press the pressure block 21 at the bottom of the adjusting plate 20, causing the adjusting plate 20 to slide in the third sliding groove, and then move the adjusting plate 20 away from the adjusting frame 10. When the adjusting plate 20 moves, the locking rod 24 can be moved out of the locking hole 12 to release the locking of the adjusting frame 10. After the adjustment is completed, the transmission shaft 13 is driven back to its original position by the elastic force of the first return spring 14, and the adjusting plate 20 is driven back to its original position by the elastic force of the second return spring 19. At this time, the locking rod 24 can be inserted into the locking hole 12 to lock the adjusting frame 10, and then lock the positions of the connecting rod 6 and the side clamp 7.
