Description

Technical Field

[0001] The present application relates to the field of rail transportation technology, and more specifically, to a suspended vehicle bogie. Background Art

[0002] Urban rail transit systems boast a small footprint, minimal pollution, and high capacity, potentially alleviating the severe congestion currently facing urban areas. This has led to the emergence of a new type of rail transit system: suspended rail transit. Suspended rail transit features bogies encased in track beams, positioned above the vehicle body. This system maintains normal operation even in inclement weather. Furthermore, because the track beams are suspended in the air, they occupy minimal urban ground area, minimizing the impact on ground traffic.

[0003] Existing suspended monorail vehicles utilize a three-phase AC permanent magnet motor coupled with a gearbox for traction. The bogies are bulky and heavy, making them difficult to navigate tight curves. Furthermore, the use of steel wheels and rails limits the bogies' gradeability, increasing the cost of constructing track beams. The stabilizing wheels on existing suspended monorail bogies are located at the four corners of the bogie, their longitudinal position nearly coinciding with their guide wheels, effectively functioning as the same wheels.

[0004] Therefore, how to reduce the total weight of the bogie and achieve a lightweight design of the bogie has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Invention

[0033] like Figure 1 As shown, an embodiment of the present application discloses a suspended vehicle bogie, comprising a frame 1, a suspension beam 25, a permanent magnet motor 10 and a running wheel 4.

[0034] The frame 1 is provided with guide wheel mounting seats 7 at both ends, and guide wheels 3 are provided on the guide wheel mounting seats 7. The guide wheels 3 are arranged symmetrically in the longitudinal and transverse directions relative to the center of the frame 1.

Figure 2 As shown in FIG, the extending direction of the straight line A in the figure represents the longitudinal direction of the frame 1, and the extending direction of the straight line B represents the transverse direction of the frame 1. Figure 1-Figure 3As shown, above the frame 1, preferably in the middle of the frame 1, there is a mounting hole 151 for mounting a stabilizing wheel mounting seat 15, which is used to mount the stabilizing wheel mounting seat 15. Preferably, the stabilizing wheel mounting seat 15 is mounted on the frame 1 by bolts, and the stabilizing wheel 14 is mounted on the stabilizing wheel mounting seat 15 by bolts. The stabilizing wheel 14 is provided on the stabilizing wheel mounting seat 15, and the number of stabilizing wheels 14 includes two. The two stabilizing wheels 14 are symmetrically arranged with respect to the longitudinal direction of the frame 1, and the line connecting the centers of the two stabilizing wheels 14 preferably coincides with the transverse central axis of the frame 1.

[0036] A motor mounting base 8 is provided in the frame 1, and a permanent magnet motor 10 is mounted on the motor mounting base 8, preferably in the middle of the frame 1. The permanent magnet motor 10 is connected to the gearbox 12 via a coupling 9. Specifically, the output shaft of the permanent magnet motor 10 is connected to the input shaft of the gearbox 12. The drive half shaft 31 of the gearbox 12 is connected to the running wheel 4 to transmit torque. The drive half shaft 31 is connected to the running wheel 4 to drive the running wheel 4 to rotate. The axis of the drive half shaft 31 is collinear with the axis of the running wheel 4.

[0037] The suspended vehicle bogie disclosed in the embodiment of the present application sets the stabilizing wheel 14 in the middle of the frame 1. The number of the stabilizing wheels 14 includes two, and they are symmetrically arranged along the longitudinal direction of the frame 1. The material of the stabilizing wheel 14 is elastic material. Compared with the prior art solution of setting the stabilizing wheel 14 at the four corners of the frame 1, the longitudinal positions of the stabilizing wheel 14 and the guide wheel 3 almost coincide with each other, which can reduce the weight of the frame 1, thereby realizing a lightweight design of the bogie; the guide wheel mounting seat 7 is installed on the gear box 12, which can simplify the structure of the frame 1; the running wheel 4 uses rubber tires, which can improve the climbing performance of the bogie.

[0038] Furthermore, the permanent magnet motor 10 is connected to the motor mounting base 8 through the permanent magnet motor connecting plate 33 at the bottom, preferably through bolt connection, which is convenient for disassembly and assembly, and facilitates the inspection and maintenance of the permanent magnet motor 10.

[0039] Furthermore, in order to make the stabilizing wheel 14 move in the transverse direction (ie Figure 2 The extension direction of the straight line B shown in FIG) has a certain running space, such as Figure 1 and Figure 2 As shown, a stabilizing wheel mounting portion 35 is provided on the stabilizing wheel mounting seat 15, and the stabilizing wheel mounting portion 35 is slidably matched with the stabilizing wheel mounting seat 15, and the stabilizing wheel mounting portion 35 can slide along the horizontal direction of the frame 1.

Specifically, for each stabilizing wheel 14, a slider is provided in the stabilizing wheel mounting portion 35, and a bearing is provided in the slider. The stabilizing wheel 14 is connected to the bearing via a stabilizing wheel support shaft. The provision of the elastic reset member 34 can reduce the rigid impact between the stabilizing wheel 14 and the frame 1, and can be adapted to the track beam. The provision of the stabilizing wheel 14 can reduce the risk of vehicle body tilt and rollover.

[0040] Furthermore, if Figure 1 and Figure 3 As shown, to enhance the structural stability of the frame 1, the frame 1 includes a top plate 16, side plates 17, and a bottom plate 13. The side plates 17 include two plates, one on each side of the top plate 16 and the other on each side, giving the frame 1 a box-like structure. This box-like structure provides high strength and rigidity, and improved bending and torsional resistance. Preferably, the side plates 17 are welded to the top plate 16 and the other plates 17, respectively. To reduce the weight of the frame 1, weight-reducing holes are provided in the top plate 16, the side plates 17, and the bottom plate 13.

[0041] Furthermore, if Figure 1 and Figure 5As shown, to transmit vertical forces and absorb and mitigate vibrations, ensuring operational stability and passenger comfort, a primary suspension 2 is installed between the frame 1 and the gearbox 12. The primary suspension 2 is located at both ends of the frame 1 and is mounted vertically between the primary suspension mounting bases on the frame 1 and the primary suspension mounting bases 29 on the gearbox 12. The primary suspension 2 is mounted on primary suspension mounting bases 29 on the frame 1 and the gearbox 12 (the primary suspension mounting bases 29 on the frame 1 are not shown). Specifically, the primary suspension mounting bases 29 on the frame 1 are box-shaped structures with one side open and are connected to the frame 1 by welding.

[0042] Further, if Figure 4 As shown, in order to isolate track vibration and ensure passenger comfort, a secondary suspension 24 is provided between the car body hanger 27 and the suspension beam 25. The secondary suspension 24 is provided at both ends of the suspension beam 25. The car body is pressed on the secondary suspension 24 through the car body hanger 27, transmitting the vertical force from the car body. The secondary suspension 24 and the primary suspension 2 work together to maintain the stability of vehicle operation.

[0043] Further, if Figure 4 As shown, to cushion the lateral swing of the suspension beam 25, an anti-sway damper 20 is provided between the vehicle body hanger 27 and the structure 1. An anti-sway damper mounting base 18 is provided on the structure 1. The anti-sway damper mounting base 18 is preferably welded to the structure 1. The anti-sway damper 20 is mounted on the anti-sway damper mounting base 18. The anti-sway damper mounting base 18 and the suspension beam mounting base 19 can be connected to the structure 1 separately, or the anti-sway damper mounting base 18 is connected to the suspension beam mounting base 19, and the suspension beam mounting base 19 is connected to the structure 1. The anti-sway damper 20 is hingedly connected to the structure 1 and the vehicle body hanger 27.

[0044] Further, Figure 3 and Figure 4 As shown, to limit the swing of the suspension beam 25, an anti-roll stop 32 is provided at the bottom of the frame 1. An anti-roll stop seat 26 is provided on the suspension beam 25 to cooperate with the anti-roll stop 32. The anti-roll stop seat 26 cooperates with the anti-roll stop 32 to limit the swing of the suspension beam 25 around the suspension pin 21. Specifically, the anti-roll stop seat 26 is preferably made of rubber.

[0045] Further, if Figure 4 As shown, to limit the lateral displacement of the vehicle body, lateral side blocks 28 are symmetrically provided on both sides of the vehicle body. When the lateral displacement of the vehicle body and the suspension beam 25 reaches the limit position, the lateral side blocks 28 limit the lateral displacement of the vehicle body. The lateral side blocks 28 are preferably made of elastic material.

[0046] Further, if Figure 4As shown, in order to suppress the lateral vibration of the car body or the bogie, a lateral vibration damper 23 is provided between the suspension beam 25 and the car body hanger 27 .

[0047] Furthermore, in order to ensure that the vehicle can continue to run when the running wheels 4 are worn, the running wheels 4 are made of rubber tires, preferably pneumatic rubber tires, specifically, Figure 6 As shown, the running wheel 4 includes a tire 401, a hub 402, and a rim 403. The tire 401 is mounted on the rim 403, which is connected to the hub 402. The hub 402 is preferably connected to the driving half-shaft 31 of the running wheel 4 via bolts, and the gearbox 12 is connected to the driving half-shaft 31. The permanent magnet motor 10 drives the driving half-shaft 31 through the gearbox 12, thereby driving the running wheel 4 to rotate. Even if the tire 401 is worn or damaged, the internal structure can still support the vehicle body. The use of rubber tires can improve the vehicle's climbing ability.
