[0002] Tracked hydraulic excavators are a common type of construction machinery, mainly used for earthwork operations such as excavation, loading, and leveling. They adopt a tracked walking mechanism with a large contact area between the tracks and the ground and a low ground pressure, enabling them to travel on complex terrains such as soft and muddy surfaces, and providing good passability and stability.

[0003] The power of the engine in a tracked hydraulic excavator is transmitted to the drive wheel via the travel motor, and then the drive wheel transmits the power to the track, causing the track to rotate and thus driving the excavator to move. However, the drive wheel of the existing tracked hydraulic excavator may be damaged when it is subjected to impact during operation. Utility Model Content
