Crawler belt deformable running gear

Abstract

The invention discloses a crawler belt deformable running gear comprising a crawler belt, a return roller, a main frame, a driving wheel assembly, a main loading wheel assembly, and an inducer wheel assembly; the return roller is arranged on the top of the main frame, and can freely rotate around the fixed axis on the main frame; the driving wheel assembly is arranged on one side of the main frame through a hinge; the inducer wheel assembly is arranged on the other side of the main frame through a hinge; the main loading wheel assembly is arranged below the main frame; the crawler belt wraps the outer side of the return roller, the driving wheel assembly, the main loading wheel assembly and the inducer wheel assembly, and the crawler belt is supported by said units to form the shape; the driving wheel assembly and the inducer wheel assembly respectively comprise a telescopic driving assembly, and the shapes on the front side and/or rear side of the crawler belt can be changed by the telescopic motions of the telescopic driving assemblies. The crawler belt deformable running gear is simple in structure, easy to realize, wide in application scope, safe and reliable.

Description

technical field [0001] The invention mainly relates to the field of ground mobile platforms, in particular to a crawler deformable walking mechanism capable of changing the contact area between the crawler belt and the ground. Background technique [0002] The crawler walking mechanism can well adapt to slippery, soft, and muddy ground shapes, and is widely used in various platforms that move in harsh ground environments, including various engineering operating vehicles (such as excavators), military special vehicles, micro Small ground mobile robot. The performance of the crawler running mechanism will directly affect the passing ability of the ground platform. [0003] Restricted by the engineering realization technology, most of the track lengths in the current crawler running mechanism are fixed. This constraint makes the existing crawler running mechanism design minimize the deformation of the track shape and add several tension wheels. To ensure that the track can be...

Problems solved by technology

Applied to the crawler running mechanism of engineering vehicles and military special vehicles, due to the relatively fixed positions of the driving wheels, induction wheels, and drag wheels, the load wheels only swing up and down slightly through the rocker arm, so that the shape of the track is mostly approximately fixed, forming a track and The ground is in contact with a large area, and it has good trafficability on slippery, soft, and muddy ground, but it will cause low traffic efficiency on hard, paved, and other ground with strong adhesion, and t
