Wherein, be equipped with drive wheel 3, leading wheel 4, bearing wheel 7 and tow band pulley 8 in the track body 5, also prop up the shaping with track body 5 through the above-mentioned four mutual cooperations. The main beam 1, the auxiliary beam 2, the damping group 6 and other structures are mutually matched, so that the bearing function is realized, and a connection point is provided, so that the driving wheel 3, the guide wheel 4, the bearing wheel 7 and the tow band wheel 8 are fixed at the designed position.

Specifically, as shown in fig. 1, a main beam 1 is taken as a center, the main beam 1 is located below a carriage body and penetrates through the whole vehicle body, two ends of the main beam 1 are respectively provided with a driving wheel 3 and a guide wheel 4, the driving wheel 3 is connected with a driving device to drive a track body 5 to rotate, and the guide wheel 4, a bearing wheel 7 and a tow band wheel 8 rotate along with the track body 5.

The main beam 1 is connected with the auxiliary beam 2 through the auxiliary beam support 101, the auxiliary beam 2 is enabled to be lifted and hung out to the center of the crawler wheel, and the number of the auxiliary beam supports 101 can be properly increased or decreased according to the length of the auxiliary beam 2, so that the bearing capacity of the auxiliary beam 2 can meet the design requirement. The vibrations that produce behind the bearing wheel 7 atress conduct to shock attenuation group 6, and shock attenuation group 6 absorbs vibrations in order to reduce the vibrations of the carriage body to improve and take experience.

When the crawler type crawler belt wheel suspension support structure works, power of a crawler is transmitted to the crawler suspension support structure through the driving wheel 3, the driving wheel 3 drives the crawler body 5 to rotate, the crawler body 5 is connected with the tow belt wheel 8, the guide wheel 4 and the bearing wheel 7, and therefore the tow belt wheel 8, the guide wheel 4 and the bearing wheel 7 also rotate respectively. As shown in fig. 1, when the crawler advances, the driving wheel 3 rotates counterclockwise to drive the crawler body 5 to rotate counterclockwise, whereas when the crawler retreats, the driving wheel 3 rotates clockwise to drive the crawler body 5 to rotate clockwise. When the road conditions are not good, the crawler can bump, the bump is transmitted to the damping set 6 from the lower part of the crawler body 5 and the bearing wheels 7, the amplitude is reduced through the buffering and the absorption of the damping set 6, the bumping degree in the carriage body is reduced, and the riding comfort is improved.
