Description

Technical Field

[0001] The utility model relates to the technical field of crawler vehicles, in particular to a crawler travel driving wheel. Background Art

[0002] Crawler travel mechanism is the travel part of crawler travel machinery and equipment, such as crawler excavators, crawler cranes, crawler bulldozers, etc. Crawler travel mechanism is mainly composed of guide wheels, tensioning devices, crawler frames, supporting wheels, drive wheels, sprocket wheels and track shoes. One of the important parts is the drive wheel, which is an important conversion device that converts engine power into machine kinetic energy. The drive wheel drives the entire machine to move. During the use of the drive wheel, due to the harsh working environment, mud and stones can easily enter the part where the crawler and the drive wheel are connected. If only mud enters, it will be relatively better. If stones enter, it is easy to damage the crawler and the drive wheel, shortening the service life of the crawler and the drive wheel. There is currently no reliable technical solution. Utility Model Content
