Power steering is an essential feature in modern vehicles, allowing drivers to steer with ease and precision. The system works by using hydraulic or electric pressure to assist the driver in turning the steering wheel. In this blog, we’ll discuss what power steering is, how it works, and the various components that make up the system.
What is Power Steering?
Power steering is a system that helps drivers turn the steering wheel with less effort. There are two primary types of power steering: hydraulic and electric. Hydraulic power steering uses fluid pressure to assist with steering, while electric power steering uses an electric motor.
How Does Power Steering Work?
In a hydraulic power steering system, a hydraulic pump is driven by the engine, pressurizing power steering fluid. The pressurized fluid is then sent to the power steering rack or gearbox, which uses the pressure to assist with turning the wheels. When the driver turns the steering wheel, a valve opens, allowing the pressurized fluid to flow into the cylinder, pushing the piston and assisting with the turn.
In an electric power steering system, an electric motor is used to assist with turning the wheels. The motor is controlled by a computer that uses sensors to detect the driver’s input and adjust the amount of assistance provided accordingly.
What Components are in Power Steering?
The power steering system is made up of several components, including:
- Power steering pump: The power steering pump pressurizes the power steering fluid, sending it to the steering rack or gearbox to assist with turning the wheels.
- Steering rack or gearbox: The steering rack or gearbox is responsible for translating the driver’s input into movement of the wheels.
- Power steering fluid: Power steering fluid is used to transmit hydraulic pressure from the pump to the steering rack or gearbox.
- Power steering hoses: Power steering hoses connect the power steering pump to the steering rack or gearbox, transmitting the pressurized fluid.
- Power steering belt or electric motor: The power steering belt drives the power steering pump in a hydraulic system, while the electric motor provides assistance in an electric system.
- Power steering fluid reservoir: The power steering fluid reservoir stores extra fluid, ensuring the system has an adequate supply.
Power steering is a critical component of modern vehicles, allowing drivers to steer with ease and precision. The system uses hydraulic or electric pressure to assist with turning the wheels. The main components of the power steering system include the power steering pump, steering rack or gearbox, power steering fluid, power steering hoses, power steering belt or electric motor, and power steering fluid reservoir. By keeping up with regular maintenance and addressing any issues promptly, vehicle owners can ensure their power steering system is functioning correctly, providing optimal steering performance and safety on the road.
