[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] Embodiment 1:

When rapid braking is required, the electronic control unit 2.9 and the hydraulic control unit 2.10 are started simultaneously to achieve the purpose of rapid braking of the brake disc 2.6.

[0068] Combination Figure 2 The bogie of the embodiment of the present invention further includes two guide wheels 2.2, which are arranged corresponding to the running wheels 2.5. The guide wheels 2.2 are arranged on the outer sides of the corresponding running wheels 2.5 along the length direction of the frame 2.1. The guide wheels 2.2 are rotatably arranged on the frame 2.1. The rotation plane of the guide wheels 2.2 is perpendicular to the rotation plane of the running wheels 2.5.
