Abstract

A motor vehicle has a housing for an energy store arranged on a bottom side of a floor assembly of the motor vehicle such that the vibrations of the floor assembly are reduced. A compressible foam of a damping component is an elastomeric foam, the material properties of which exhibit, under dynamic loading, dynamic hardening, so that the stiffness under dynamic loading starting from a frequency of greater than 0.1 Hz is greater by a dynamic hardening factor, which is greater than 2, than the stiffness which is present under quasistatic loading, such as when fitted for example.
