Among them, the main supporting beam 1 is connected to the main frame 2 by a plurality of bolts. The rear part of the main supporting beam 1 is connected to the drive connection unit 6 by a plurality of bolts. A hydraulic system is arranged inside the frame inside the main supporting beam 1. The supporting wheel group 4 is provided with two or more groups, each wheel group and the driving device are separately installed on the main supporting beam 1, and each part is independent and convenient for disassembly and assembly. The separate inner drive hub 7 and the outer drive hub 8 are respectively connected to the drive connection unit 6; the driving force is provided by the drive connection unit 6, and the crawler 5 is driven to rotate by the drive hub to provide a walking function.

[0027] The driving wheel hub of the present invention adopts a separated wheel hub. The uniqueness of its type and its installation structure ensure the convenience and practicality of the device. The main supporting beam 1 is a double-layer box-type frame and a rear drive connection offset structure. The outer side is the main load-bearing frame, the middle and rear part is the main structure for installing the supporting wheel group 4, and the front part is the main structure for installing the guide device 3; the inner frame is responsible for the connection with the main frame 2, and the hydraulic system is arranged inside; the rear mounting plate is responsible for the connection with the main frame 2 and the driving wheel group. The uniqueness of this structural type ensures the bearing capacity and multi-zone distribution of functions of the device. In addition to the inner and outer driving hubs connected to the drive unit, the rear drive can also be designed as a driving tooth 9 to replace the inner and outer driving hubs connected to the drive unit.

The guide device 3 and the supporting wheel group 4 (here only the beam body of the guide device 3 and the supporting wheel group 4 are connected, and the outer wheels are not connected temporarily) are connected to the main support beam 1 as the second layer structure; the outer wheels of the guide device 3 and the supporting wheel group 4 are connected to the main support beam 1 as the third layer structure. The crawler 5 can be connected to the main support beam 1 after the second layer structure is connected, and then the third layer structure is connected.

[0029] The present invention adopts a multi-layer structural unit form, the main body has a strong bearing capacity, realizes multi-layer functional distribution, is independent of each other, improves bearing capacity, and is easy to install, disassemble and maintain later.
