Passive self-adaption caterpillar structure

Abstract

The invention discloses a passive self-adaption caterpillar structure. The passive self-adaption caterpillar structure is characterized by comprising a support, a power wheel, a front guide wheel and a caterpillar, the support is an inner framework used for supporting the caterpillar and comprises a support body, four to six supporting frames and two to four tensioning frames, the support body is in rigid connection with a caterpillar truck body through bolts, the front guide wheel is arranged at the front end of the support body, the power wheel is arranged at the rear end of the support body, the tensioning frames are evenly distributed on the upper side of the support body, the supporting frames are evenly distributed on the lower side of the support body, each supporting frame comprises a supporting frame base, a supporting rod, a supporting frame spring and a supporting wheel, and each tensioning frame comprises a tensioning frame base, a tensioning rod, a tensioning frame spring and a tensioning wheel. The passive self-adaption caterpillar structure can pass through an uneven terrain smoothly, and the contour of the caterpillar can be adjusted passively according to specific terrains so that it can be ensured that the caterpillar makes contact with the ground completely to the maximum extent. On the premise that the functional requirements are met, the passive self-adaption caterpillar structure has the advantages of being simple in structure, convenient to control, low in energy consumption and the like.

Description

technical field [0001] The invention relates to the technical field of crawler vehicles, in particular to a passive adaptive crawler structure. Background technique [0002] Tracked vehicles have strong passability on uneven terrain, and are widely used in military, agricultural, engineering machinery and other fields. In order to further improve the motion performance of tracked vehicles, a variety of new track structures have been designed. For example, in the patent document "New Track Structure for Vehicles (CN2409111Y)", magnetic force is used to reduce the positive pressure on the track chain plates to improve mechanical efficiency; in the patent document "A Track Structure (CN202175123U)", components such as drive motors and transmission mechanisms Integrated in the inner frame supporting the track to realize the miniaturization of the tracked car body, thereby improving the flexibility of movement; "Analysis of Obstacle Crossing Performance of Four-link Deformed Tra...

AI Technical Summary

Problems solved by technology

First, when the tracked car body is driving on uneven terrain, it is difficult to completely contact the track and the ground, which affects friction and easily causes slippage

Second, in the existing crawler structure, rigid connections are used between the supporting wheels and the bracket, so that the crawler body is prone to bumps when passing through uneven terrain (especially stepped roads)
