GD2 Damper D 280/20/V/M
Product Description
The damper consists of a primary and a secondary section. Between these, groups of leaf spring packs are arranged, clamped at their outer ends. These spring packs - together with the primary and secondary sections - form chambers, which are filled with oil. If the exterior section vibrates in relation to the inner one, the leaf springs are bent and force the pressurized engine oil from one chamber into another, retarding the relative movement of the two parts and thus damping the torsional vibration. The elasticity is determined by careful choice of leaf springs and the damping factor by the gaps, which interconnects the oil chambers.
