Complete guide of Hydraulic and electric power steering
Technology is constantly changing, especially in cars. Regardless of whether it’s due to safety features or upgrades that are made in mechanical systems, there are always new things that come out each year. In fact, a lot more automobile manufacturers are now making cars with electronic power steering systems. In any case, a majority of vehicles on the road these days still use hydraulic steering systems. It’s critical to have some knowledge about the type of power steering system your car has.
Electric power steering provides better fuel economy
Cars with EPS systems do not come with hydraulic pumps or pistons. However, they come with a more simplified electric motor designed to augment the steering commands made by drivers. This method reduces the amount of weight in the vehicle. Also, the EPS system doesn’t use power from the engine as the hydraulic systems do. Overall, the electric power steering system is more efficient.
Less maintenance is needed for electric power steering systems
It‘s obvious that cars containing hydraulic power steering need fluid to operate. The vehicles with EPS have one less type of fluid to be concerned about. In addition to that, it’s easier to calibrate cars with electric systems. Typically, all it needs is a small tweak in the programming.
Which system handles better?
The system that offers the best handling to drivers is still a topic that’s often debated. Some feel that the hydraulic system provides a better feel for the road and that the EPS system has a tendency to make the driving experience somewhat dull. Since these opinions are subjective, you should get behind the wheel of an EPS vehicle and try it out for yourself.
Hydraulic power steering
The steering gear’s internal cavity is divided into two chambers by a sealed piston attached to the rack. By applying pressurized hydraulic fluid to one side of the piston while allowing fluid to return from the other side to a reservoir provides steering assistance. A valve attached to the pinion shaft controls the hydraulic-fluid flow.
Studies reveal total votes in seven out of ten rating categories favored EPS by two to eight points each. Hydraulic shined in only the three Feedback categories where it won the on-center comparison by four points and tied with EPS in our middle-of-maneuver and at-cornering-extremes performance ratings.
