Types of Power Steering Pulleys

Power steering pulleys play a critical role in the smooth operation of a vehicle’s steering system. They are responsible for transmitting power from the engine to the power steering pump, which in turn assists the driver in turning the steering wheel. There are several types of power steering pulleys, each with its own unique design and function.

Belt-Driven Pulleys

Belt-driven pulleys are the most common type of power steering pulley. They are typically made of metal or composite materials and have a series of grooves around their circumference. A serpentine belt, which is a continuous loop of rubber, runs around the grooves on the pulley and connects it to the engine’s crankshaft. As the engine runs, the crankshaft turns the belt, which in turn rotates the power steering pulley.

Chain-Driven Pulleys

Chain-driven pulleys are similar to belt-driven pulleys, but they use a chain instead of a belt to transmit power. Chains are typically more durable than belts and can handle higher loads, making them suitable for vehicles that require more steering assistance.

Electrically-Assisted Power Steering (EPS) Pulleys

EPS pulleys are found in vehicles with electric power steering systems. These systems do not use a hydraulic pump to assist the steering, but instead rely on an electric motor to provide the necessary force. EPS pulleys are typically smaller in size than belt-driven or chain-driven pulleys and are mounted directly on the steering column.

Variable Displacement (VD) Power Steering Pulleys

VD pulleys are designed to vary the amount of fluid flow to the steering system based on the vehicle’s speed. This is achieved by using a variable displacement pump, which can adjust the flow rate of the fluid in response to changing driving conditions. VD pulleys are typically used in vehicles with variable assist steering systems, which provide varying levels of steering assistance depending on the vehicle’s speed.

Tandem Power Steering Pulleys

Tandem pulleys are used in vehicles with multiple power steering pumps. These pumps are typically used in vehicles with four-wheel steering or other systems that require additional steering assist. Tandem pulleys have two or more grooves around their circumference, with each groove connecting to a different power steering pump.

Additional Features of Power Steering Pulleys

In addition to their primary function of transmitting power, power steering pulleys may also incorporate additional features to enhance the performance and reliability of the steering system. These features can include:

Pully alignment marks: Alignment marks help to ensure that the pulley is properly aligned with the power steering pump and other components. Incorrect alignment can lead to premature wear and tear on the pulley and other components.
Balancing weights: Balancing weights are used to reduce vibrations in the steering system. Vibrations can cause noise and discomfort, and can also lead to premature wear and tear on the steering components.
Overrun clutches: Overrun clutches are used to allow the pulley to freewheel in the opposite direction of rotation. This helps to reduce noise and wear on the pulley and other components.
Damping materials: Damping materials are used to absorb vibrations in the steering system. This helps to reduce noise and discomfort, and can also improve the steering feel.
