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 damping component id provided as an elastomeric spring, 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 quasi-static loading, such as when fitted for example.
Claims8
A motor vehicle with a body shell having a passenger cell, comprising:
- a floor;
- a housing structure for energy-storage devices fastened to an underside of the floor, wherein the housing structure is a closed container with a trough-shaped component and a cover spaced from the trough-shaped component;
- at least one damping component arranged in an interspace between the underside of the floor and an external surface of the cover of the housing structure, which at least one damping component has been installed in a compressed state in the interspace between the cover of the housing structure and the floor,
- wherein
- the at least one damping component is a compressible, an elastomer spring, material properties of which under dynamic loading exhibits a dynamic hardening, so that under dynamic loading starting from a frequency greater than 0.1 Hz;
- a stiffness is greater, by a dynamic hardening factor that is greater than 2, than the stiffness that is present under quasi-static loading.
