Technical Field

The invention relates to the field of design of rubber tracks for tracks, in particular to a high-speed T-shaped associated tooth root-wrapped tooth top type anti-drop rubber track.

Background

At present, the small-sized crawler-type military vehicles mostly adopt rubber tracks, and the design of the rubber tracks required by a chassis directly influences the weight of devices such as arrangement, structure, wheel trains and the like of each wheel train.

Although the rubber track structure has difference according to different vehicle demands, the annular arrangement mode, the equal pitch arrangement and the anti-falling driving function of the whole rubber track have universality in principle. Modern anticreep area rubber track all comprises direction tooth, two side drive teeth, and very big influence the structural style and the arrangement mode of each train, and rubber track main part weight is heavier, and two side drive teeth appear the root easily and peel off or undercut phenomenon.
