As a driver, you know that the steering wheel is that part of the car which allows you to have control over your vehicle. But have you ever wondered how it is that rotating the steering wheel makes the front wheels move, and keeps them moving? To answer this question, you need to consider the power steering gearbox. This means that you need to understand how the steering box and the steering gear work.
What Is the Role of the Power Steering Gearbox?
The combination between the steering box and the steering gear makes your car’s steering system, which converts the circular movement you make with the steering wheel into the motion of the vehicle’s front wheels, which move to the left and to the right. This is what allows you to make a turn, change lanes, or go past another car.
This function is essential and your car can’t function properly without it. That is why this part of your vehicle must be durable. The materials used in making it need to be very solid to prevent easy deterioration.
How Does the Power Steering Gearbox Work?
The commands sent by the steering wheel to the gearbox are interpreted in relation to the pressure exerted. When you turn the steering wheel, the vehicle turns thanks to power steering. How does this happen? A fluid pump sends the power steering fluid up through pressure lines into the steering gearbox.
What Are the Main Components of a Power Steering Gearbox?
The internal components of the gearbox are contained in a gearbox housing, which is generally made of resilient cast iron. There are four line inlets built into the casing of the gearbox. One is connected to the reservoir, another to the pump, and two leading to the fluid lines.
There is a rotary valve inside the gearbox, which senses the pressure applied with the help of the steering wheel. This valve works only when it detects pressure. When the movement is straightforward, the rotary valve doesn’t do much. Other key components of the power steering gearbox are the torsion bar, the shafts, and the power piston.
