ABSTRACT:
An elastic engine mount with a dynamic stiffness decreasing in dependence on frequency for damping sound transmitted through solids includes a leaf spring having a central region and ends, an elastomer support disposed on the central region of the leaf spring for transmitting force to the leaf spring in a given direction and loading the leaf spring by bending, and at least two support points supporting the leaf spring, the ends of the leaf spring extending freely beyond the support points forming auxiliary masses coupled to the elastomer support vibrating in a direction opposite to the given force transmission direction.
