Method for absorbing the kinetic energy and a device for absorbing the kinetic energy

摘要

Kinetic energy created by an impact is converted into kinetic energy of rotary motion by driving at least two rotary kinetic energy accumulators (4, 5, 6) into rotary motion in order to increase the energy accumulation ability depending on the impact energy magnitude, whereas the rotary kinetic energy accumulators (4, 5, 6) are successively driven into rotary motion by means of driving elements started successively by the ram element (1) shifted in the result of impact force. In a device for taking over kinetic energy, a ram (1) element cooperates with at least two racks (2) driving toothed wheels (3, 3a, 3b, 3c) of the rotary kinetic energy accumulators (4, 5, 6) having different energy accumulation abilities, whereas distances (7, 8, 9) are provided between the ram element (1) and the racks (2) driving toothed wheels (3, 3a, 3b, 3c) of the rotary kinetic energy accumulators (4, 5, 6), said distances providing an idle stroke of the ram element (1) in relation to the racks (2).
