Coil Spring - J4402040 HERTH+BUSS JAKOPARTS

Coil springs are made of strong steel rods. When the wheel moves down, the spring straightens, and when it moves up, it contracts, so the height of the body relative to the ground practically does not change.

The HERTH+BUSS JAKOPARTS brand Coil Spring is a strong steel bar coil. It contracts and straightens when the wheels move in a vertical plane.

The spring not only supports the weight of the vehicle and maintains the nominal ride height when the vehicle is stationary or driving on the road.

The ability of a spring to resist compression is called stiffness - this is the main characteristic of a spring.

Material and functions of the coil spring

Springs are made of special torsion steel, which, when deformed, tends to return to its original position. The damper is usually located inside or near the spring.

The main functions of the spring are to maintain the weight of the car, reduce vibrations and shocks transmitted from the road surface to the body, maintain good tire adhesion to the road, and maintain the correct ground clearance (ground clearance).
