How many double-acting hydraulic steering cylinders are present in the system?

In hydraulic steering systems, double-acting cylinders are designed to provide force in both directions, allowing for improved maneuverability and control. There are typically multiple double-acting hydraulic cylinders in these systems, which are essential for steering applications that require precise movements and balance.

The presence of four double-acting hydraulic steering cylinders is based on common design practices in automotive and heavy machinery systems. Having four cylinders allows for effective steering assistance while maintaining a tight and stable configuration, facilitating responsive steering inputs. This setup enhances the overall performance of the steering mechanism, ensuring that the vehicle or machinery can be operated smoothly even under varying loads and conditions.

Thus, the choice of four double-acting hydraulic steering cylinders reflects an understanding of the requirements for optimal hydraulic steering performance, making it the correct answer.
