springdæmper

A springdæmper, commonly known as a shock absorber, is a mechanical device designed to absorb and damp shock impulses. Its primary function is to control the oscillations of a spring, converting kinetic energy into heat through fluid friction. In vehicles, springdæmpers are crucial for ensuring a smooth ride by preventing the suspension from bouncing excessively after encountering bumps or irregularities in the road surface. They work in conjunction with springs, which absorb the initial impact, while the springdæmper dissipates the energy from the spring's rebound.

The most common type of springdæmper utilizes a piston moving within a cylinder filled with hydraulic fluid. As the piston moves, the fluid is forced through small orifices, creating resistance. This resistance slows down the movement of the piston and, consequently, the oscillation of the spring. The design and viscosity of the fluid are critical factors in determining the damping characteristics. Different types of springdæmpers exist, including telescopic, lever arm, and blade types, each suited for specific applications. Beyond automotive use, springdæmpers are found in various mechanical systems, such as aircraft landing gear, industrial machinery, and even in some types of furniture to improve comfort and stability. Proper maintenance and replacement of springdæmpers are essential for maintaining vehicle handling, safety, and passenger comfort.
