Embodiment 1
[0114] The bogie 300 of the present embodiment 1 adopts a passive multi-link suspension system, such as figure 2 As shown, the bogie 300 may include: a frame 1 , two traveling wheels 2 , four guide wheels 3 , four stabilizing wheels 4 , a vertical suspension device 5 , a steering knuckle 6 and a lateral suspension device 7 . Two traveling wheels 2, four guide wheels 3, four stabilizing wheels 4, a vertical suspension 5, a steering knuckle 6 and a lateral suspension 7 are all directly or indirectly installed on the frame 1.
[0115] Such as figure 2 As shown, the running wheels 2 are connected to the frame 1 to support the vehicle body 200 and provide the driving force required for the operation of the vehicle body 200. In addition, the brake device can also be connected to the frame 1 to provide the driving force required for the operation of the vehicle body 200. Braking force. As shown in Figure 8, the frame 1 includes a first frame part 11, a second frame part 12 and a ...
Embodiment 2
[0123] The bogie 300 of the second embodiment adopts a semi-active multi-link suspension system. Specifically, the structure of the bogie 300 of the second embodiment is substantially the same as that of the first embodiment above, the main difference is that the second embodiment improves the vertical adapting member 55, the horizontal Adapt to the type selection of the piece 74, and add a vertical vibration detection device 56 and a lateral vibration detection device 75. The specific description is as follows:
[0124] In the second embodiment, the vertical adapting member 55 is a magneto-rheological shock absorber, the vertical vibration detection device 56 is a vertical vibration acceleration sensor, and the control current of the vertical adapting member 55 is controlled by the central control unit of the vehicle body 200. control, the central control unit of the car body 200 can analyze the current vibration situation of the car body 200 according to the data measured b...
Embodiment 3
[0128] The bogie 300 of the third embodiment adopts a fully active multi-link suspension system. Specifically, the structure of the bogie 300 in the third embodiment is substantially the same as that in the second embodiment above, the main difference is that the third embodiment improves the selection of the lateral adapting member 74 on the basis of the second embodiment above , and the vertical vibration detection device 56 is canceled, and the track beam detection device 76 is added. The specific description is as follows:
[0129]In the third embodiment, the lateral adapting member 74 is a magnetic linear DC actuator, and the function of the lateral adapting member 74 is to provide active force for the guide wheel 3 and the stabilizing wheel 4 . The track beam detection device 76 is an ultrasonic sensor, and is installed on the frame 1 of the bogie 300, and can monitor the information of the side surface 1002 of the track beam 100 in front of the guide wheel 3 and the st...
