What type of hydraulic pump is most commonly used in steering systems?

In steering systems, axial piston pumps are favored because of their ability to provide high pressures and precise control, which are critical in ensuring responsiveness and reliability in steering mechanisms. These pumps can produce a consistent flow of hydraulic fluid and can effectively manage varying load conditions, making them ideal for applications where the steering effort needs to be modified based on vehicle dynamics and speed.

Axial piston pumps have a design that allows for efficient fluid movement and can operate at high pressures while maintaining a compact size. This combination of features is essential in steering systems, where space can often be limited, and high performance is required to ensure steering accuracy and safety.

In contrast, while vane pumps and gear pumps are used in various hydraulic applications, they do not offer the same level of efficiency or precision control as axial piston pumps in the context of steering. Centrifugal pumps, although effective in many fluid transfer applications, are not typically suitable for steering systems due to their inability to generate the high pressures required for effective steering control.
