Types of Drive Belt Tensioners
Drive belt tensioners are essential for maintaining proper tension in the drive belt, ensuring that it operates efficiently. Below are the main types of drive belt tensioners:
- Automatic Tensioner: This is the most common type of tensioner used in modern vehicles. It adjusts the tension automatically as the belt wears over time, ensuring consistent performance.
- Spring Loaded Tensioner: This type uses a spring to apply constant pressure to the drive belt. It's found in both older and some modern vehicles and is known for its reliability and simplicity.
- Hydraulic Tensioner: Hydraulic tensioners use hydraulic fluid to maintain constant tension. These are more common in high-performance engines or vehicles that require more precise control of belt tension.
