How Do Suspension Parts Work?

The suspension parts of a vehicle help ensure a smooth and comfortable ride. Plus, they keep the tires in contact with the road. It’s a complex system that comprises several parts, each with its unique function.

The shock absorber or strut is the most crucial part of the suspension system. The shock absorber works by dampening the wheels’ vertical movement, which helps keep the tires in contact with the road.

It consists of a piston that moves up and down inside a cylinder, with oil or gas filling the space between them. When the wheels encounter bumps on the road, the shock absorber compresses, which absorbs the energy of the impact and prevents it from being transmitted to the vehicle’s body.

The spring is also important, as it helps to absorb shocks and vibrations caused by the road surface. It is typically a coil-shaped metal component that compresses and expands as the wheels move up and down.

The sway bar, also known as the stabilizer bar, is another essential part of the suspension system. A metal bar connects the vehicle’s left and right wheels, helping reduce body roll during cornering. The sway bar resists the twisting forces when the car turns, keeping the vehicle stable and preventing excessive body roll.

Finally, the control arms, or A-arms, are critical components of the suspension system. They connect the other suspension parts to the vehicle’s frame and control the vertical movement of the wheels.
