What kind of parts does the hydraulic cylinder of hydraulic power steering drive the steering mechanism to act?

The hydraulic cylinder in hydraulic power steering is primarily responsible for actuating the steering mechanism, which is directly linked to the drag link. When hydraulic pressure is applied within the cylinder, it creates a force that moves the piston inside the cylinder, allowing the steering system to translate this force into motion. This motion is then transmitted through the drag link to turn the wheels of the vehicle.

The drag link serves as a critical component within the steering system, connecting the steering gear to the steering knuckle, and this connection allows the steering mechanism to pivot effectively, changing the direction of the vehicle. In hydraulic power steering, the assistance provided by the hydraulic cylinder enables smoother and more effortless steering, especially during low-speed maneuvers or when the vehicle is stationary.

The other components, such as the steering wheel, axle, and drive shaft, play different roles in the vehicle's operation but are not directly actuated by the hydraulic cylinder in terms of steering function. The steering wheel is the driver's input for steering, the axle supports the weight of the vehicle and allows for wheel rotation, and the drive shaft transmits power from the engine to the wheels. Thus, the correct understanding is that the hydraulic cylinder's action primarily affects the drag link in driving the steering mechanism
