Power steering uses a hydraulic or electric pump to provide assistance to the steering system. This assistance is provided by applying pressure to the steering fluid, which in turn helps to move the steering components. Power steering can make it easier to turn the steering wheel, especially at low speeds or when the vehicle is stationary. This makes power steering useful for vehicles that are heavy or have large tires, such as trucks and SUVs.
Assisted steering, on the other hand, does not use any power assistance. Instead, assisted steering systems use a variety of mechanical components to reduce the amount of effort required to turn the steering wheel. These components can include gears, pulleys, and springs. Assisted steering systems can make it easier to turn the steering wheel, but they do not provide the same level of assistance as power steering. This makes assisted steering more suitable for smaller vehicles or vehicles that are used at higher speeds.
In general, power steering is the more popular option for most vehicles. This is because power steering provides the most assistance and makes it the easiest to turn the steering wheel. However, some people prefer assisted steering because it provides a more direct feel for the road. This can be beneficial for drivers who want to feel more in control of their vehicle.
Ultimately, the best steering system for a particular vehicle depends on the driver's preferences and the type of vehicle.
