Undercarriage System Overview
The excavator undercarriage is a critical component responsible for
supporting and propelling the entire machine, ensuring stable
operation across various terrains. Its primary functions include
providing power, supporting the machine's frame, transmitting
driving force, and ensuring mobility and stability in complex
environments.
Key Components
- Travel Motor (Hydraulic Motor): Supplies driving force by converting hydraulic energy into
mechanical energy to rotate the tracks.
- Track (Crawler Belt): Directly contacts the ground, providing traction and stability.
Typically made of high-strength steel to adapt to different
terrains.
- Sprocket (Drive Wheel): Connects the travel motor to the track, transmitting power to move
the track.
- Idler Wheel (Guide Wheel): Guides the track's movement and maintains proper alignment,
usually located at the front.
- Carrier Rollers (Bottom Rollers): Support the machine's weight and distribute pressure evenly to
reduce ground impact.
- Track Rollers (Top Rollers): Support the upper part of the track, preventing sagging and
ensuring smooth operation.
- Track Frame (Undercarriage Frame): Supports and secures all components, ensuring structural
stability.
