The address of our car is made up of several elements. Thanks to the combination of all the elements involved in steering, we can turn our vehicle in a comfortable and simple way, as well as have correct alignment.
In the direction of our car we can basically find four main elements, as we detail below:
Parts of the steering of a car
A car's steering is made up of several components that work together to allow control and maneuverability of the vehicle. Among its basic elements we have the following:
- Defensive Midfielder: It is the component that is inside the vehicle and that the driver uses to turn and control the direction of the car.
- Steering column: It is a bar that connects the steering wheel with the steering system. It transmits the movements of the steering wheel to the steering components.
- steering box: is the mechanism responsible for transmitting the movement of the steering wheel to the front wheels of the car. It can be a rack and pinion or recirculating ball steering box, depending on the type of system used.
- Tie Rod Ends: They are ball joints that allow the connection between the steering rod and the front wheels. They allow steering movement and rotate along with the wheels.
- suspension ball joints: These are joints similar to the steering knuckles, but they are found in the suspension system. They connect suspension components, such as control arms, to the wheels and allow movement of the suspension.
- suspension triangles: are suspension components that connect to the vehicle's chassis and wheels. They can be lower triangles and upper triangles, and their function is to maintain the position and control the vertical movement of the wheels.
- Silent blocks: They are rubber or polyurethane elements that are used in the suspension and steering to provide isolation and vibration absorption. They are found at various mounting points, such as the suspension triangles and other steering components, and help improve vehicle comfort and stability.
These are some of the main parts of a car's steering, but keep in mind that the exact configuration and components may vary depending on each vehicle's specific steering system and design.
Power steering
La power steering It is a system designed to facilitate the movement of the steering wheel and provide a smoother and more comfortable steering for the driver, especially at low speeds and during parking manoeuvres. Helps reduce the effort required to turn the steering wheel, making the vehicle easier to control.
There are various types of power steering systems, but the most common is hydraulic power steering and electric power steering:
- Hydraulics:
- power steering pump- A belt-driven motor supplies the hydraulic power for the system. The power steering pump, usually driven by the vehicle's engine, forces pressurized hydraulic fluid into the system.
- Control valve: The hydraulic fluid is directed to a control valve that regulates the flow of fluid based on the movement of the steering wheel.
- Power steering cylinder: Hydraulic fluid under pressure is directed to a power steering cylinder, which is connected to the vehicle's steering gear.
- Turning assistance: When the driver turns the steering wheel, the control valve senses the movement and directs more flow of hydraulic fluid to the power steering cylinder, helping to turn the wheels with less effort.
- Electrical:
- Electric motor: In this system, the electric motor is located on the steering column or directly in the steering gear.
- Direction sensor: A sensor detects the position and movement of the steering wheel and sends this information to the system's electronic controller.
- Turning assistance: Based on information from the steering sensor, the electronic controller determines the amount of assistance required and activates the electric motor to provide the necessary assistance.
Possible faults in the direction
Here are some possible faults that can occur in a car's steering system:
- play in steering: Refers to excessive play or loose movement in the steering wheel when turning. It can be caused by wear on steering components such as tie rod ends or steering box gears. Backlash can affect steering precision and response, which can be dangerous and require repair.
- steering wheel vibrations: If you feel vibrations or jolts in the steering wheel while driving, it may indicate a problem with the steering system. This can be caused by wheel imbalance, tire wear, wheel bearing problems, or steering misalignment. It is important to investigate and fix the problem, as vibrations can affect stability and driving comfort.
- Steering misalignment: misalignment occurs when the front wheels do not point in the same direction. It can be caused by bumps on curbs, potholes in the road, or uneven tire wear. Misalignment can cause uneven tire wear, unstable steering, and poor response when turning. It should be corrected by adjusting the wheel alignment.
- power steering fluid leak: If you have hydraulic power steering and you notice the presence of steering fluid on the ground under your vehicle, it may be indicative of a leak in the system. Leaks can occur in the hoses, power steering pump, or seals. A fluid leak can affect steering assist capabilities and requires repair to maintain proper system function.
- Noise or screeching when turning the steering wheel: If you hear noise or screeching when you turn the steering wheel, it may be an indication of a problem with the steering system. This can be caused by worn steering components, lack of lubrication, or power steering pump belt problems. It is recommended to inspect and fix the problem to avoid possible system failure.
- Problem with slintblocks: It is also convenient to check them and replace them if necessary. In these pieces we can find noises, vibrations and a strong metallic impact.
Maintenance
Un good steering maintenance of the car is crucial for several reasons:
- Safety: it is a critical component in maintaining vehicle control. Good maintenance ensures that the steering works correctly, which contributes to driving safety. A faulty or improperly adjusted steering system can compromise the vehicle's responsiveness and increase the risk of accidents.
- Control and driving comfort: A steering system in good condition allows for more precise and controlled handling of the vehicle. Misaligned steering, looseness or vibrations can negatively affect the stability, handling and responsiveness of the vehicle. Proper maintenance ensures that steering components are in top condition and that wheels are properly aligned, providing smooth, precise handling.
- Tire Durability: Proper steering maintenance helps extend tire life. Improper alignment or worn steering can cause uneven tire wear, resulting in reduced tire life. By keeping the steering properly adjusted and aligned, you ensure even tire wear, which in turn reduces premature replacement costs.
- Repair costs: Regular preventative steering maintenance can help detect and fix problems before they become major, costly-to-repair failures. Early identification of wear and tear on steering components allows them to be addressed early and prevents further damage to the system.
Also, after changing any of the items that we've been talking about today, it's important align direction of our car to finish fine-tune and correct problems that we had.
