               1. Final Drive (行走马达): Located on the undercarriage, it converts hydraulic pressure into the rotational force that drives the tracks. Example: Sandvik DD421 Final Drive (行走马达) (Конечная передача).                        
               2. Hydraulic Pump (液压泵): The heart of the hydraulic system, it generates the fluid pressure needed to power various functions. Example: Atlas Copco ROC F7 Hydraulic Pump (液压泵) (Гидравлический насос).                        
               3. Swing Motor (回转马达): Mounted in the upper structure, it provides the rotational power for the machine's house. Example: Epiroc MB 1700 Swing Motor (回转马达) (Поворотный редуктор).                        
               4. Undercarriage (底盘件): The lower part of a tracked machine, including the tracks, rollers, and idlers. It supports the machine's weight and provides propulsion.                        
               5. Track Shoe (履带板): The individual plates that make up the track of a tracked vehicle, providing traction.                        
               6. Sprocket (驱动齿): A toothed wheel that engages with the track to drive the machine forward.                        
               7. Idler (导向轮): A wheel at the front of the track frame that guides the track and maintains tension.                        
               8. Engine Cylinder Head (发动机缸盖): The top cover of the engine cylinder, sealing the combustion chamber.                        
               9. Turbocharger (涡轮增压器): A device that increases engine power by forcing more air into the combustion chamber.                        
               10. Water Pump (水泵): Circulates coolant through the engine to prevent overheating.
