Transformable caterpillar

Abstract

The invention discloses a transformable caterpillar, which comprises a chassis, wherein two sides of the chassis are symmetrically provided with crawler belt walking mechanism; each crawler belt walking mechanism comprises a first crank and a second crank which are parallel to each other; the upper ends of the first and second cranks are movably hinged to a first connecting rod by virtue of screws, the lower ends of the first and second cranks are movably hinged to the vertex angle parts of two V-shaped supports respectively through screws, and the middle sections of the first and second cranks are movably connected with a second connecting rod by virtue of screws; the first connecting rod is provided with bearing wheels; two bottom angle parts of each V-shaped support are provided with driving wheels; third connecting rods are connected with the driving wheels; crawler belts are wound on the driving wheels and the bearing wheels; the chassis is provided with a crawler belt spacing adjusting mechanism. The transformable caterpillar has the advantages that the transformation mechanisms can be used for adjusting the gravity center of the caterpillar and width between wheels when the caterpillar encounters a barrier, the body of the caterpillar is enabled to pass a steep road surface smoothly, and the caterpillar has good movement stability.

Description

[0001] technical field [0002] The invention relates to a crawler vehicle, in particular to a deformed crawler vehicle whose width between crawler wheels and the height of the center of gravity of the vehicle body can be adjusted according to different terrains. Background technique [0003] Traditional tracked vehicles can use the large contact surface with the ground to obtain high stability, but the terrain adaptability is poor. Increasing the number of tracks can make the tracked vehicle better adapt to the terrain, but this will increase the weight and make the structure complicated , complicating the manipulation. If the shape of the track can be adjusted according to different terrains, and the track spacing is increased, that is, the width of the car body, and the center of gravity of the car body can be adjusted, then the car body can pass through steeper roads and up and down slopes more smoothly.

Problems solved by technology

[0004] In order to solve the problem that the existing crawler vehicles cannot change in time to adapt to different terrains, the invention provides a deformable crawler vehicle, which adopts a parallelogram mechanism, a screw transmission mechanism, and a hydraulic transmission of a hydraulic column, and has good terrain adaptability. The tracked vehicle can deform to increase the width between the track wheels, reduce the height of the center of gravity of the tracked vehicle, and adjust the position of the center of gravity to maintain greater grip and stability, so as to pass smoothly.
