The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a track wheel assembly comprises a driving wheel 21, a bogie wheel 22, a track 20 arranged on the driving wheel 21 and the bogie wheel 22 in a transmission manner, and an inner suspension 23 for supporting the track, wherein the track 20 comprises a chain link 1 and a track connecting pin 2, and a plurality of sections of the chain link 1 are sequentially hinged end to end through the plurality of track connecting pins 2 to form an annular track chain link; two free end portions of each chain link 1 in track 20 are provided with respectively by driving piece 7, the axial both ends of action wheel 21 are coaxial respectively and are provided with initiative rim plate 24, two initiative rim plate 24 sets up in the terminal surface outside of 1 two free ends of chain link respectively in the clearance, action wheel rim plate 24 corresponds the setting with by driving piece 7, driven piece 7 follow-up on the chain link of drive 24 wheel face contacts of initiative rim plate when initiative rim plate 24 rotates drives each chain link 1 through initiative rim plate 24 and rotates in proper order, rotates from the side direction drive track through action wheel 24 to avoid trompil on the track face, promote the intensity of track, reduce and warp.

The driving wheel disc 24 is of a gear disc structure, and the driven part 7 is correspondingly meshed with the gear teeth on the driving wheel disc 24. An example of a driven member 7 is: the driven member 7 is a gear structure with the tooth tips facing the driving wheel disc 24 and is meshed with the driving wheel disc. Fig. 1 shows another embodiment: the chain link 1 comprises chain plates 3 and a track connecting pin shaft 2 hinged with each chain plate 3, two ends of the track connecting pin shaft 2 respectively extend outwards along the axial direction, and a shaft body extending out of two sides of the chain link 1 forms a driven part 7. The two free ends of the track connecting pin shaft 2 correspond to the gear teeth on the two driving wheel discs, the shaft end of the track connecting pin shaft 2 corresponding to the free ends is driven to rotate through the rotation of the driving wheel discs, so that the track is driven to transmit, the whole mounting structure is simple, transmission holes do not need to be formed in the track surface, the deformation of the track can be reduced, and the stress of each chain link 1 can be more balanced through the two driving wheel disc structures on the two sides, and the stability of track transmission is ensured.

Action wheel 21, bogie wheel 22 are the cylinder gyro wheel structure, and it all is located the track inner circle, just all encircle on the outer circumferential wall of action wheel 21, bogie wheel 22 and be equipped with and lead positive annular groove 26, each link 1 all is provided with induced tooth 6 on one side towards the track inner circle, induced tooth 6 corresponds the setting with leading positive annular groove 26, induced tooth is located leads positive annular groove 26, leads the transmission of positive track through leading positive annular groove 26 when the track transmission.
