How many types are there in steering systems based on power source?

[MacLeilani]

Automotive steering systems are categorized into two types based on the power source: mechanical steering systems and power steering systems. Introduction to Mechanical Steering Systems: Mechanical steering systems use the driver's physical strength as the steering power source, hence they are also known as manual steering systems. They consist of three main components: the steering control mechanism, the steering gear, and the steering linkage. The steering gear is typically fixed to the vehicle frame or body, and the steering force usually changes direction after passing through the steering gear. Introduction to Power Steering Systems: Power steering systems convert part of the engine's mechanical energy into pressure energy (hydraulic or pneumatic energy). Under the driver's control, this system applies hydraulic or pneumatic forces in different directions to the steering linkage or a specific component within the steering gear, thereby reducing the steering effort required from the driver. This system is referred to as a power steering system.
