- Key functions & working principle
| Working Principle |
1. Tension Application: The coil spring inside the tensioner exerts a constant force on the tensioner arm, pushing the idler pulley against the serpentine belt to maintain optimal tension (800–1,200 N). |
| 2. Self-Adjustment: As the belt stretches over time (normal wear), the tensioner arm rotates to compensate, keeping tension within the required range – no manual adjustment needed. |
| 3. Vibration Damping: The hydraulic damper slows down rapid movement of the tensioner arm (caused by engine vibration or load spikes), preventing belt flutter and slippage. |
| 4. Power Transfer: Proper tension ensures the belt grips the accessory pulleys (alternator, water pump) without slipping, transferring engine power to drive critical accessories. |
| Core Functions |
1. Belt Tension Control: Maintains optimal tension on the serpentine belt to prevent slippage (which causes overheating, accessory underperformance, and belt wear) |
| 2. Vibration Reduction: Hydraulic damping minimizes belt vibration and flutter – extends belt service life (from 2,000 to 5,000+ hours) |
| 3. Self-Adjustment: Eliminates manual tension checks/adjustments – reduces maintenance downtime |
| 4. Accessory Power Assurance: Ensures consistent power delivery to alternators (battery charging), water pumps (engine cooling), and air compressors (brake/hydraulic systems) – prevents equipment breakdowns |
