IMPACT ENERGY ABSORBING DEVICE OF A CRASH BOX FOR A VEHICLE, CAPABLE OF APPLYING A CRASH BOX TO ALL KINDS OF VEHICLES IN COMMON

摘要

PURPOSE: An impact energy absorbing device of a crash box for a vehicle is provided to freely adjust absorption amount of impact energy according to viscosity of viscous fluid, number of diaphragm members, number of fluid passing holes, and size of the holes.;CONSTITUTION: An impact energy absorbing device of a crash box for a vehicle comprises viscous fluid(41) filling in an internal space of a crash box(30). When the crash box is crushed by impact force of collision and rear-end collision, viscous fluid absorbs impact energy by using friction due to incompressibility and viscosity of the viscous fluid while spreading to the internal space of the crash box.;COPYRIGHT KIPO 2012
