The Cummins 3805947 V Ribbed Belt is a component designed for use in commercial trucks. It serves a significant role in the operation of these vehicles by facilitating the transfer of power from the engine to various auxiliary systems. Understanding its purpose and functionality is key to maintaining the efficiency and reliability of truck operations.

Basic Concepts of V Ribbed Belts

V Ribbed Belts are a type of drive belt characterized by their trapezoidal cross-section, which allows them to fit into corresponding grooves on pulleys. This design enhances grip and reduces slippage, making them suitable for high-load applications ¹. In automotive applications, V Ribbed Belts drive multiple components such as the alternator, water pump, and air conditioning compressor. They differ from flat belts and timing belts in their construction and the way they interact with pulleys, offering advantages in terms of efficiency and durability ².
