Power Steering

Power steering is a system that helps drivers steer vehicles by augmenting the steering effort needed to turn the steering wheel, making it easier to maneuver the vehicle. This system is particularly beneficial when driving at low speeds or when parking, as it reduces the physical effort required to turn the wheels.

Basic Function

The primary function of power steering is to assist the driver in steering the vehicle. It does this by using hydraulic or electric actuators to add controlled energy to the steering mechanism, so the driver does not have to exert as much force. There are two main types of power steering systems:

• Hydraulic Power Steering (HPS): Utilizes hydraulic fluid to transmit power from the steering wheel to the steering mechanism. A pump driven by the engine pressurizes the hydraulic fluid, which then assists in turning the wheels.
• Electric Power Steering (EPS): Uses an electric motor to provide steering assistance. This system is more energy-efficient than hydraulic systems and can be more easily integrated with advanced driver-assistance systems (ADAS).

Operation

In a hydraulic power steering system, the engine-driven pump maintains hydraulic pressure in the system. When the driver turns the steering wheel, a valve opens, allowing the pressurized fluid to flow into a cylinder that assists in turning the wheels. In an electric power steering system, sensors detect the steering input from the driver and an electric motor provides the necessary assistance.

Maintenance

Regular maintenance of the power steering system is crucial to ensure its proper functioning. For hydraulic systems, this includes checking the power steering fluid level and condition, and inspecting hoses and belts for wear and leaks. For electric systems, maintenance is generally less intensive, but it is important to ensure that the electrical connections and sensors are functioning correctly.

Failure

Power steering systems can fail due to various reasons, including fluid leaks, pump failure, or electrical issues. Common symptoms of power steering failure include:

• Difficulty in steering, especially at low speeds.
• Unusual noises when turning the steering wheel.
• Steering wheel vibration or jerking.
• Warning lights on the dashboard.

If any of these symptoms occur, it is important to have the power steering system inspected and repaired by a qualified technician to ensure safe vehicle operation.
