Among them, the stabilizing wheel can be clamped on the track beam to solve the side rolling phenomenon of the bogie during operation.

[0047] According to an embodiment of the present invention, a reinforcing rib 138 is provided between the motor mounting seat 132 and the protruding end.

[0048] Please continue to see Figure 2 Since the motor is relatively heavy, in order to reduce the vertical load applied by the motor on the extended end and to improve the installation stability of the motor, a reinforcing rib 138 is provided at the position corresponding to the extended end and the motor mounting seat 132. The motor mounting seat 132 is generally a plate-shaped structure, and the motor mounting seat 132 is installed at the edge of the extended end.

Thus, the occupied space of the frame 100 can be reduced, ensuring the compact structure of the bogie.

[0050] In the embodiment of the utility model, the frame 100 integrates longitudinal and vertical hard stops to protect the bogie in the track beam. The frame 100 of the bogie has a simple and compact structure, is easy to install and disassemble, and is easy to repair, which effectively optimizes the structure of the bogie.
