Rubber spring elements used in some vehicles with independent wheel suspension may work in tension, squeezing, torsion and shear. The most common are rubber spring elements, subject to compressive and torsional loads. Rubber absorbs energy better than steel and is therefore more suitable for suspension components. However, making such a suspension is quite expensive. An important advantage of rubber spring elements is this, that they do not require any lubrication. The rubber column spring consists of several rubber rings separated by metal spacers and mounted on a common pin. It is embedded in the suspension in a similar way to a coil spring.
