power steering pump drive belt

V-ribbed belts, also known as serpentine belts, are characterized by their unique design that features multiple longitudinal ribs on the belt's inner surface. These ribs grip the pulleys during rotation, enhancing the belt's ability to transfer torque efficiently. The cross-sectional shape of a V-ribbed belt resembles a series of V's, hence the name. Typically made from rubber or a composite material, these belts offer flexibility and resilience, making them suitable for a wide range of applications.

The core of a variable belt drive consists of a pair of pulleys connected by a belt. These pulleys can change in diameter or spacing, which alters the effective gear ratio between the input and output. By adjusting the distance between the pulleys or changing the width of the belts, operators can control how power is transmitted and at what speed. Hydraulic, mechanical, or electronic methods often facilitate these adjustments, making the system versatile in responding to different operational demands.
