What Is the Steering System? How Is the Steering Box Repaired?

What Is the Steering System? How Is the Steering Box Repaired?
The steering system controls the parts that help the vehicle move in the desired direction.
Although steering wheels often look like a simple ring, in new-generation vehicles they may include buttons that control the audio system, vehicle systems, and other functions.
The connection between the steering wheel and the vehicle wheels is provided by a shaft. These shafts have gear rods; movement of these rods turns the gear wheel on the wheel, and that wheel movement steers the tire.
What Is Hydraulic Steering?
With the development of the automotive industry, the number of hydraulic steering systems has increased significantly.
The most noticeable feature of hydraulic steering is the lightness felt when taking corners.
The basic purpose of the hydraulic system is to let the driver turn the steering wheel without fatigue.
Oil pumping is what makes this system work.
These steering systems have many parts. This means more weight, more space, and considerably higher cost.
Automatic parking and lane-keeping systems cannot be applied on hydraulic steering.
What Is an Electric Power Steering System?
This system, which has spread rapidly in new-generation vehicles, has largely replaced hydraulic steering.
The main reason electric steering has become so widespread is lower fuel consumption and lower maintenance cost because fewer parts are involved.
What Are the Parts of the Steering System?
The most basic part of the steering system is the steering wheel. Other parts include the steering shaft, damper, hydraulic pump, steering joint, idler arm, gear box, and similar components.
What Are the Advantages of Electric Power Steering?
Electric steering helps the vehicle consume less fuel.
They also consist of fewer parts, which means lower maintenance cost.
The structure is quite simple — it is the lightest steering type and takes up less space in the vehicle. Driving safety is better with this type of steering.
Steering System — General Overview
Steering box means the steering wheel and steering gear working together.
Without either of these two parts, the steering system cannot work properly.
These two parts convert the circular motion you make on the steering wheel into left and right movement of the front wheels.
Steering assembly is quite easy because many brands produce units that fit many models.
Steering System Faults
Faults in the steering system usually appear as unusual noises when turning the wheel, stiff or hard steering, and excessive play in the steering wheel.
There are also faults caused by incorrect front-end alignment.
Hydraulic Steering System Faults
These steering faults are usually noticed by noise from the steering oil pump while the engine is running.
Among hydraulic steering faults are a broken or loose power steering pump belt, low steering fluid (when the level drops, the steering warning light comes on on the instrument cluster and the steering becomes stiff), and noise when turning the wheel.
Factors That Make Steering Harder to Turn
1 — The best-known effect is when the vehicle is stationary or moving very slowly.
The main reason is friction between the tire and the ground. In this situation the steering is quite stiff and more force is needed to turn it.
As speed increases, the force needed to turn the steering wheel decreases.
2 — Vehicle weight is another factor that makes steering harder. Heavy-duty vehicles (trucks, tractors, construction machinery…) carry much more load, so turning the steering wheel is harder than on passenger cars.
The main reason is the higher pressure the tire applies to the ground.
3 — Wide tires require more force when turning the steering wheel.
These and many similar factors make the steering wheel harder to turn.
How Is Steering Repair Done?
Repairing and returning steering boxes to the market is of great importance to the national economy.
Refurbishing worn and failed products and putting them back on the market has a positive effect on national wealth.
When repairing steering, the failed part must first be identified.
To do this effectively and reliably, test devices and test benches designed for this work are required.
After fault localization on steering boxes with these test devices, the identified part should be replaced with a new one or the failed part should be repaired.
Which Device Is Used for Steering Repair?
For repairing these parts, Nitro Group has brought another innovation to the sector and signed a distribution agreement with MSG for steering box repair.
MSG is a European manufacturer and is CE certified.
With MSG steering diagnostic tools produced by MSG, you can repair and maintain steering faults very easily.
You can also perform steering calibration with MSG steering test devices.
