Abstract

Decoupling devices for an electric motor in relation to a housing usually have decoupling bushes made of elastic material, which are disposed between a motor mount and the housing and extend along a bush longitudinal axis. The decoupling device includes a first contact point at which the decoupling device rests against the motor mount, and a second contact point at which the decoupling device rests at least indirectly against the housing, each decoupling bush is secured so that the decoupling bush can be radially deflected in relation to the bush longitudinal axis, by means of which the forces are in fact transmitted, but vibrations are damped or insulated.
