1.26. Knowing the parts of a vehicle: Arms suspension system

Página 27

The suspension system with overlapping arms is one of the most crucial parts of a vehicle, as it absorbs the impacts and irregularities of the terrain, providing a smooth and comfortable ride. In addition, it also contributes to the stability of the vehicle, especially in curves and fast maneuvers, ensuring the safety of the driver and passengers.

The trailing arms, also known as swinging arms, are the linking components between the vehicle's structure and the wheels. They are usually made of steel or aluminum and are designed to move up and down in response to road irregularities. This movement is controlled by springs and dampers, which absorb and dissipate impact energy.

The double-arm suspension system consists of several components, the main ones being the upper link, the lower link, the spring, the shock absorber and the stabilizer bar.

The upper link and lower link are the components that connect the wheel to the vehicle frame. They are designed to move independently of each other, allowing one wheel to move up and down without affecting the position of the other wheel. This is especially useful on uneven terrain, where it is common for one wheel to be on a different level from the other.

The spring is the component that absorbs the impact energy. It is made of steel and is designed to compress when the wheel passes over an obstacle, absorbing the impact energy. It then expands again, returning the wheel to its original position.

The damper is the component that controls the movement of the spring. It is filled with a viscous fluid that is forced through small holes when the spring compresses and expands. This creates resistance to movement, which helps control the speed at which the spring moves, preventing excessive oscillations.

The anti-roll bar is a component that connects the two suspension arms on one side of the vehicle to the other. It helps keep the vehicle stable when cornering by reducing the vehicle's tendency to lean to one side. When the vehicle makes a turn, the stabilizer bar helps transfer power from one side of the vehicle to the other, keeping all wheels on the ground and the vehicle stable.

Knowing and understanding the wishbone suspension system is essential for proper vehicle maintenance. Regular and proper maintenance of this system can extend the life of components, improve vehicle performance and ensure safe and comfortable driving.

In addition, a good understanding of this system can help identify potential problems before they become serious. For example, a strange noise or unstable ride could indicate a problem with the suspension arms, springs or shock absorbers. Identifying and correcting these problems early can avoid costly repairs and extend the life of your vehicle.

In summary, the wishbone suspension system is a crucial part of the vehicle that contributes to a smooth, comfortable ride and vehicle stability. Knowing and understanding this system can help ensure proper maintenance and identify potential problems, contributing to vehicle safety and longevity.
