Summary

In this video, the presenter explains the functioning of a power steering system, breaking down its key components and how they work together. He covers essential parts like the reservoir tank, hydraulic pump, rotary valve, power cylinder, and pinion, offering insight into how the system eases steering by providing additional torque. The process of steering left and right is also thoroughly explained, emphasizing the role of the rotary valve in controlling the flow of power steering fluid. The video aims to provide a comprehensive yet easy-to-understand guide to how power steering systems operate.

Takeaways

• 😀 Power steering helps make the steering wheel easier to turn by using hydraulic pressure.
• 😀 The key components of the power steering system include the reservoir tank, pump, belts, poly gallery, and rotary valve.
• 😀 The rotary valve is crucial for controlling the flow of power steering fluid, allowing the steering wheel to turn left or right.
• 😀 The power steering pump is powered by the engine through a poly gallery belt, which drives the hydraulic system.
• 😀 The power cylinder pushes the fluid to the left or right side, enabling easier turns depending on the direction.
• 😀 A pinion gear, connected to the steering wheel, helps in turning the wheels left or right by interacting with the rotary valve.
• 😀 The power steering system reduces the effort required to turn the steering wheel from 2-4 kg to as light as 0.5 kg or less.
• 😀 In a straight driving position, the hydraulic pressure is equal on both sides of the power steering, keeping the steering neutral.
• 😀 When turning left, the rotary valve opens a specific path to allow fluid to push the power cylinder to the left, making it easier to turn.
• 😀 When turning right, the rotary valve shifts to open the right-side path, directing fluid to the power cylinder to push it right, making the turn smoother.
• 😀 The system continuously recycles fluid from the reservoir tank to maintain the necessary pressure and fluid levels for steering assistance.

Q & A

What is the main function of the power steering system?

The main function of the power steering system is to assist in turning the steering wheel, making it easier for the driver to maneuver the vehicle by reducing the effort required to rotate the wheel.

What is the role of the reservoir tank in the power steering system?

The reservoir tank stores and supplies the hydraulic fluid (power steering fluid) needed for the power steering system to function.

How does the power steering pump work?

The power steering pump is responsible for circulating the hydraulic fluid throughout the system. It generates pressure that is needed to assist the movement of the steering wheel.

What is the function of the rotary valve in the power steering system?

The rotary valve controls the flow of power steering fluid to the left or right side of the power cylinder, directing the fluid to assist in turning the steering wheel in the desired direction.

What happens when the steering wheel is turned to the left?

When the steering wheel is turned to the left, the rotary valve opens the left-side fluid pathway, sending hydraulic fluid to the left power cylinder. This helps push the steering mechanism, turning the wheel in that direction.

What happens when the steering wheel is turned to the right?

When the steering wheel is turned to the right, the rotary valve opens the right-side fluid pathway, sending hydraulic fluid to the right power cylinder, which helps push the steering mechanism, turning the wheel in that direction.

What is the pressure control valve's role in the system?

The pressure control valve regulates the pressure of the hydraulic fluid. If the pressure exceeds a certain level (usually around 80 kg/cm²), it is redirected back into the reservoir to prevent damage to the system.

How does the pinion gear work in the power steering system?

The pinion gear engages with the steering rack and, when rotated, moves the rack left or right. This movement assists in turning the wheels in the desired direction, in coordination with the hydraulic assistance.

What are the components connected to the steering wheel in the power steering system?

The components connected to the steering wheel include the steering column, rotary valve, and the pinion gear, all of which are integral in transmitting the driver's input to the steering mechanism.

How does the power steering system reduce the effort needed to turn the steering wheel?

The power steering system reduces the effort needed by using hydraulic assistance. With the help of the power steering fluid, the system applies force to the steering mechanism, making the steering wheel much easier to turn, requiring much less physical effort.
