Key Differences
Power Steering is a technology that employs a mechanism to amplify the effort applied by the driver to steer the vehicle, making it easier to maneuver. Electric Power Steering, while also assisting in maneuvering, utilizes an electric motor to amplify the driver's steering effort without employing hydraulic systems.
Power Steering, historically often relying on hydraulic systems, utilizes fluid to transmit the necessary force to assist in steering. In contrast, Electric Power Steering eliminates the need for hydraulic fluid by employing an electric motor to aid in steering, thereby generally being more energy-efficient.
Power Steering systems usually consist of components like a hydraulic pump, a cylinder, and various connecting hydraulic lines to operate. Electric Power Steering, with its electric motor, significantly simplifies the system, often resulting in reduced maintenance and enhanced reliability.
The operation of Power Steering might involve a bit more maintenance than Electric Power Steering, owing to the potential for hydraulic leaks and the necessity of ensuring that the fluid is at the appropriate level. On the other hand, Electric Power Steering tends to be less maintenance-intensive due to the absence of hydraulics.
In terms of energy efficiency, Power Steering generally requires continuous energy from the engine to maintain hydraulic pressure, which could slightly impact fuel efficiency. Electric Power Steering typically shines in the realm of energy efficiency as the electric motor only draws power when steering assistance is needed.
