Description

Technical Field

[0001] This utility model relates to a load-bearing component for the drive wheel of a tracked vehicle, the drive wheel of a tracked vehicle, and the tracked vehicle. Background Technology

[0002] Tracked vehicles are vehicles that use a tracked propulsion system instead of a traditional wheeled system. They possess excellent traction and low ground pressure, enabling them to adapt to harsh environments such as snow, hillsides, and grasslands. The treads on the track plates prevent the vehicle from slipping on rain, snow, ice, or uphill surfaces. The drive sprocket is the core component of the tracked propulsion system, converting engine power into traction. It drives the vehicle by engaging with the track plates and, in conjunction with the brakes, achieves braking. The axle is the load-bearing structure of the drive sprocket and plays a crucial role.
