Abstract

The invention relates to the technical field of crawler machines, in particular to a crawler assembly and a crawler machine. The crawler assembly in the present invention comprises a crawler belt, a thrust wheel which is arranged on the crawler belt and comprises two wheel bodies, and a limiting device, wherein the two wheel bodies are coaxially connected, and a groove is formed between the two wheel bodies; and the limiting device comprises a limiting piece, and the limiting piece is arranged on the crawler belt in a lifting mode and inserted into the groove. Therefore, even if the crawler belt is separated from the thrust wheel, the limiting device can still keep in contact with the groove to limit the relative lateral sliding between the crawler belt and the thrust wheel so that the derailment risk of the crawler belt can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of crawler machinery, in particular to a crawler assembly and a crawler machinery. Background technique [0002] In the crawler track assembly of crawler machinery such as excavators, the supporting rollers are arranged on the track, mainly to support the weight of the whole machine and evenly distribute the weight of the whole machine on the track. [0003] During work, it is necessary to prevent the track from sliding sideways relative to the rollers, so as not to affect the normal walking of the whole machine. [0004] In the related technology, the lateral surface of the roller body is a cylindrical surface, and the surface of the crawler track that matches the cylindrical surface of the roller body is a plane, and the axial end of the wheel body is provided with a limit step, and the limit step cooperates with the track roller. , to limit the lateral slip between the track and the rollers. [0005] Ho...
