Method and device for decoupling mass for a motor vehicle

Abstract

The invention relates to a mass-decoupling device for a motor vehicle, having: a mass-receiving element () and a mass object () accommodated therein, which mass-receiving element () and mass object () are point symmetrically formed and mounted opposite a body () of the motor vehicle; at least one guide means () that moveably mounts the mass-receiving element () and the mass object () accommodated therein along a longitudinal axis (L) of the vehicle; decoupling means () designed to decouple the mass-receiving element () and the mass object () accommodated therein from the body () of the motor vehicle; first energy-receiving means () designed to transmit kinetic energy of a movement of the mass-receiving element () and the mass object () accommodated therein to the body () of the motor vehicle in a predetermined time interval, said movement occurring along the longitudinal axis (L) of the vehicle, from a first position (P) to a second position (P); and second energy receiving means () designed to convert, at least partially, the kinetic energy of the movement of the mass-receiving element () and the mass object () accommodated therein along the longitudinal axis (L) of the vehicle into kinetic energy of a rotation of the mass object (). The invention also relates to a corresponding method for decoupling mass for a motor vehicle.
