Embodiment 1

[0077] Such as Figure 4 and Figure 5 As shown, the frame 1 may include: a frame 11, a frame foot 12 and a frame ear 13, the frame 11 defines a vertically penetrated frame hole 111, and the running wheel 2 is passed through the frame hole 111, that is to say, the running wheel 2 A part passes through the frame hole 111 to the bottom of the frame 11 , and a part of the traveling wheel 2 passes through the frame hole 111 to the top of the frame 11 . The frame ear 13 is located on the top of the frame 11, the traveling wheel installation assembly 3 is connected between the frame 11 and the frame ear 13, the axle 20 of the traveling wheel 2 is located above the frame 11 and is supported by the traveling wheel installation assembly 3, and the frame foot 12 is provided At the bottom of the frame 11 , the stabilizing wheels 7 are mounted on the feet 12 .

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

Embodiment 2

[0084] Such as Figure 11 and Figure 12 As shown, the frame 1 may include: a frame 11 and a stand 12, the frame 11 defines a vertically penetrated frame hole 111 and a through hole 112, and the traveling wheel 2 is passed through the frame hole 111, that is to say, the traveling wheel 2 A part passes through the frame hole 111 to the bottom of the frame 11 , and a part of the traveling wheel 2 passes through the frame hole 111 to the top of the frame 11 . The traveling wheel installation assembly 3 is penetrated through the via hole 112, that is to say, a part of the traveling wheel installation assembly 3 passes through the via hole 112 to the top of the frame 11, and a part of the traveling wheel installation assembly 3 passes through the via hole 112 to the frame 11 below. The axle 20 of the traveling wheel 2 is located above the frame 11 and is supported by the part of the traveling wheel mounting assembly 3 located above the frame 11 , the frame foot 12 extends downwar...

Embodiment 3

[0172] The bogie 300 of the third embodiment adopts a fully active suspension system. Specifically, the structure of the bogie 300 in the third embodiment is substantially the same as that in the second embodiment above. Wheel adaptation device 83 selection. 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 the guide wheel 5 with a driving force for active action. When the car 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 car body 200, and the central control unit actively adjusts the action of the guide wheel adaptation device 63 to drive The guide wheel 5 actively moves to actively reduce the impact and vibration of the bogie 300 from the unevennes...

Abstract

The invention discloses a bogie, a monorail vehicle and a monorail traffic system. The bogie comprises a framework, walking wheels, guide wheels, stabilizing wheels and stabilizing wheel installationassemblies, the walking wheels, the guide wheels, the stabilizing wheels and the stabilizing wheel installation assemblies are arranged on the framework, the stabilizing wheels are installed on the framework through the stabilizing wheel installation assemblies, each stabilizing wheel installation assembly comprises a stabilizing wheel adaptation device, and the stabilizing wheel adaptation devices provide transverse adaptation force for the stabilizing wheels. According to the bogie for the monorail vehicle, vibration transmitted from the side face of the rail beam can be attenuated through the stabilizing wheel adaptation device, so that the adaptation situation of the stabilizing wheel to the side face of the rail beam can be improved, and then the running stability and riding comfort of a vehicle body are improved. In addition, the contact yield of the stabilizing wheels on the two sides of the track beam to the side faces of the track beam can be increased to a certain extent, sothat a vehicle body runs in the middle as much as possible and passes through a curve 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 usually 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 so that the car body can run along the track beam. Among them, the bogie is the main bearing part 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. Contents 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 transmitt...
