Bilfjær

Bilfjær, also known as car springs or suspension springs, are essential components of a vehicle's suspension system. Their primary function is to absorb shocks and vibrations from the road surface, ensuring a smoother and more comfortable ride for occupants. They also play a crucial role in maintaining tire contact with the road, which is vital for steering, braking, and overall vehicle stability.

The most common type of bilfjær is the coil spring, which is a helical torsion spring. These springs compress and decompress as the vehicle encounters bumps and dips. Other types include leaf springs, which are made of several layers of metal strips stacked together, and torsion bars, which are metal rods that twist to absorb energy. The design and material of bilfjær are carefully chosen to balance ride comfort with handling performance.

Over time, bilfjær can weaken or break due to constant stress, fatigue, or corrosion. Symptoms of worn-out springs include a noticeable sag in the vehicle's stance, excessive bouncing, bottoming out over bumps, and uneven tire wear. Replacing worn or damaged bilfjær is important for maintaining vehicle safety and optimal performance. The process typically involves specialized tools and knowledge to safely remove and install the springs.
