Question

rewrite the below-working principle of hydraulic power steering system in your own word with out missing the general concept of the principle

In this type of power steering system as we discussed above the hydraulic force is used to multiply the steering input force in order to smoothen the steering of the front wheels. This hydraulic force is generated by a series of components that include a hydraulic cylinder, rotator hydraulic pump, hydraulic lines, highly compressed hydraulic fluid, and a coupling mechanism that can couple this hydraulic system with the rack of the steering system.

• When the driver provides input by rotating the steering wheel, the hydraulic pump driven by the engine starts pumping the highly compressed hydraulic fluid through lines.

• The hydraulic pressure produced by the pump enters the hydraulic cylinder which in turn applies pressure over the cylinder’s piston.

• The piston which is under high pressure starts moving from one end to the other which in turn pushes the further fluid through lines, with this movement of piston the input force applied by the driver is multiplied several times.

• This high-pressure fluid sent by the hydraulic cylinder then applies the pressure to the attached pinion through the coupling mechanism which in turn applies high force to the rack gear and the steering action in the front wheels takes place.

Answer 1

• In this type of power steering system, the hydraulic force is used to multiply the steering input force in order to smoothen the steering of the front wheels. The hydraulic force workers under the series of components like a hydraulic cylinder, rotator hydraulic pump, hydraulic lines, highly compressed hydraulic fluid,and a coupling mechanism and a coupling mechanism that can couple is hydraulic system with the rack of steering system.

• As the steering fluid from the rotary valve gets redirected into the hydraulic chamber, we start to get power assist! But let’s take a step back and see how it all happened. In the hydraulic chamber, there is a hydraulic piston right down the middle. It separates the hydraulic chamber into two equal portions: the left side, and the right side. The steering fluid gets redirected into these two chambers, but here’s the twist – they don’t get equal amounts of steering fluid! When there is more steering fluid on one side of the hydraulic chamber, it creates a pressure differential across the chamber. The steering fluid then pushes the hydraulic piston towards the weaker side of the hydraulic chamber and the steering rack moves accordingly. Because of fluid dynamic. Or, more specifically the Bernoulli’s equation. To give you a metaphor that helps you understand it, imagine two rooms of equal sizes with a movable wall that you can push in the middle. One room is filled with 50 people while the other is filled with 100 people. Because it’s so hot and stuffy in the room, I would push the wall so that I can get more space in my room. But hey, the other room want more space as well! Very quickly, this becomes a tug of war where the stronger team pushes the wall to the other side. Anyway, this “pushing of the wall” is what gives us the extra power. Since both ends of the steering rack is connected to the car wheels, when the steering rack move to the right, so will the car wheels. The car changes direction and steering fluid flows back to the steering fluid reservoir to repeat the entire process again.

• Just like how we have a petrol tank for petrol, we have a steering fluid tank for steering fluid. Whenever we are using fluid, we always have a container that holds them when we are not using them. There is nothing too fancy about this part here, and its purpose is quite self-explanatory too. But, the journey of a hydraulic power steering begins here. When we fill the steering fluid, we put it into this reservoir. It holds the fluid, and supplies them to the steering pump through rubber hoses.

• These high pressure steering fluid then leaves the steering pump, through the steering hoses and into the steering rack, specifically into the rotary valve.

• Inside the steering rack, we have what is known as the rotary valve. A rotary valve is a highly sensitive metal casing with strategically placed holes that redirects the steering fluid either back to the steering pump or into the steering rack. If the steering wheel is in its original position, the rotary valve redirects the steering fluid back to the steering pump and nothing happens. The cycle of steering fluid moving from reservoir to pump and to rotary valve just keeps repeating itself. But when the driver turns the steering wheel, the rotary valve opens up and steering fluid from the steering pump gets redirected. This time, it doesn’t go back to the steering pump but it exits the rotary valve through the fluid lines and into one of the hydraulic chamber of the steering rack.

I JUST REWROTE THE QUESTION WHICH YOU HAVE GAVE WITH SOME DIFFERENT WORDS WITHOUT MISSING GENERAL CONCEPT AND WORKING PRINCIPLE. SO THAT YOU CAN UNDERSTAND EASILY. I HOPE YOU UNDERSANT THE CONCEPT WELL
