Hydraulic vs. Electric Power Steering

The power steering system is dependent on various parts; it functions to provide easier maneuverability and more control over a vehicle. It is also known as the steering assist system or SAS. Without the SAS, steering would be physically demanding to perfect. Power steering systems can either be hydraulic, electric, or a combination of both. 


Without power steering, you won't be able to move side to side or turn left and right seamlessly. The hydraulic or electric energy assists this mechanism by multiplying the force applied by the driver through the steering wheel. As a result, your car will usually have an immediate response when you make the slightest adjustments on the steering wheel. 


How Does Hydraulic Power Steering Work?

Hydraulic power steering is what it sounds like; the system relies on fluid to intensify the force applied to move your front wheels. A pump pressurizes the hydraulic fluid. When you move the steering wheel, hydraulic pressure is applied to your steering gear, which turns your wheels. The more you turn your wheel, the more fluid streams to the hydraulic cylinder, so the more force is applied to your wheels.


How Does Electric Power Steering Work?

The electric power steering uses a motor to draw energy for steering assistance instead of power steering fluid. There are various sensors in place to measure the torque that the driver applies to the steering wheel, and the computer then determines how much "assist" needs to be added. The major benefit of electric power steering is that it can adapt to your driving conditions.


Both hydraulic and electric power steering require maintenance over time. If you ignore it, you might start to experience difficulty turning the wheel. Otherwise, your steering should be effortlessly responsive. Please schedule an appointment online with Robbie's At Your Service today!
