Device for the absorption of shock energy by plastic deformation for motor vehicles

摘要

The invention relates to a device for absorption of shock energy by plastic deformation according to the principle of the rolling bending for motor vehicles, with a tubular receiving section (1.1) and a tubular, relative to the receiving section (1.1) and of reduced substantially coaxially to this aligned intrusion section (1.2), which in the event of an impact under rolling bending of at least partially into the receiving section (1.1), and with a transition region (1.3), in which the intrusion section (1.2) continuously into the receiving section (1.1) which. In order to ensure that a device of this type a which is as uniform as possible, consistently high force level in order to achieve a high energy consumption even with an uneven loading by an oblique impact, the invention proposes that the intrusion section (1.2) of conical design, so that the same of its end facing away from receiving section (1.1) in the direction of the transition region (1.3) is conically tapered.
