Embodiment 1

[0077] like Figure 4 and Figure 5 As shown, the frame 1 may include: a frame 11, frame feet 12 and frame ears 13, the frame 11 defines a frame hole 111 that penetrates vertically, and the running wheel 2 passes through the frame hole 111, that is, the running wheel 2 A part of the running wheel 2 passes through the frame hole 111 to the bottom of the frame 11 , and a part of the running wheel 2 passes through the frame hole 111 to the upper part of the frame 11 . The frame lug 13 is arranged on the top of the frame 11, the running wheel mounting assembly 3 is connected between the frame 11 and the frame lug 13, the axle 20 of the running wheel 2 is located above the frame 11 and is supported by the running wheel mounting assembly 3, and the frame feet 12 are provided. At the bottom of the frame 11 , the stabilizing wheel 7 is mounted on the legs 12 .

[0078] Therefore, the frame 11 has a simple structure, is easy to process, and facilitates the installation of the running...

Embodiment 2

[0084] like Figure 11 and Figure 12 As shown, the frame 1 may include: a frame 11 and a frame foot 12, the frame 11 defines a frame hole 111 and a through hole 112 that pass through vertically, and the running wheel 2 passes through the frame hole 111, that is, the running wheel 2 A part of the running wheel 2 passes through the frame hole 111 to the bottom of the frame 11 , and a part of the running wheel 2 passes through the frame hole 111 to the upper part of the frame 11 . The traveling wheel mounting assembly 3 passes through the via hole 112 , that is, a part of the traveling wheel mounting assembly 3 passes through the via hole 112 to the top of the frame 11 , and a part of the traveling wheel mounting assembly 3 passes through the via hole 112 to the frame. 11 below. The axle 20 of the running wheel 2 is located above the frame 11 and is supported by the part of the running wheel mounting assembly 3 located above the frame 11 .

[0085] Therefore, the frame 11 has...

Embodiment 3

[0172] The bogie 300 of the third embodiment adopts a fully active suspension system. Specifically, the structure of the bogie 300 of the third embodiment is substantially the same as the structure of the second embodiment above. Selection of wheel adaptation device 83. The specific description is as follows:

[0173] In the third embodiment, the guide wheel adapting device 63 is a permanent magnet DC linear actuator, and the function of the guide wheel adapting device 63 is to provide an actuating force for the guide wheel 5 to act actively. When the vehicle body 200 is running on a straight road section, the information on the side surface 1002 of the track beam 100 collected by the guide wheel detection device 65 is fed back to the central control unit of the vehicle body 200. The central control unit actively adjusts the action of the guide wheel adapting device 63 to drive the The guide wheel 5 actively moves to actively reduce the impact vibration of the bogie 300 from...

Abstract

The invention discloses a bogie, a monorail vehicle and a monorail traffic system. The bogie includes a frame and running wheels, guide wheels, stabilizing wheels, and guide wheel mounting components arranged on the frame, and the guide wheels pass through the frame. The guide wheel mounting assembly is mounted on the frame, and the guide wheel mounting assembly includes a guide wheel adapting device, and the guide wheel adapting device provides a lateral adapting force to the guide wheel. According to the bogie for a monorail vehicle of the present invention, the vibration transmitted from the side surface of the track beam can be attenuated by the guide wheel adapting device, so that the adaptability of the guide wheel to the side surface of the track beam can be improved, thereby improving the running of the vehicle body Smoothness and ride comfort. In addition, the contact yield of the guide wheels on both sides of the track beam to the sides of the track beam can also be improved to a certain extent, so that the vehicle body can travel in the center as much as possible and pass the curved road section more smoothly.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a bogie, a monorail vehicle and a monorail transportation system. Background technique [0002] A monorail vehicle generally includes a track beam, a car body and a bogie, and the bogie is connected between the car body and the track beam to carry the car body and enable the car body to run along the track beam. Among them, the bogie is the main bearing component of the car body, and its performance determines the running quality and driving safety of the car body. However, due to the large vibration transmitted from the side of the track beam to the bogie, the running quality and ride comfort of the car body are affected. SUMMARY OF THE INVENTION [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a bogie for a monorail vehicle, which can improve the vibration t...
