Method for varying the spring rigidity of an elastomer mount, and corresponding elastic mount
First Claim
1. An elastic engine mount for motor vehicles, comprising first and second rotationally symmetrical rubber bodies disposed one above the other in series;
- an engine mount plate;
a support plate;
said first rubber body being fixed between said engine mount plate and said support plate;
a retaining plate to be pivoted at a vehicle body;
each of said support and retaining plates having a rim;
said second rubber body being fixed between and bounded by said support plate and said retaining plate;
an annular housing surrounding and partly encompassing said second rubber body, said annular housing having two end surfaces, one of said end surfaces being rigidly connected to one of said support and retaining plates, the other of said end surfaces encompassing said rim of another of said support and retaining plates with play; and
spreading means operating between said support plate and said retaining plate for bringing said support and retaining plates into contact with said housing so as to bridge said second rubber body.

Abstract
A method for varying the spring rigidity of an elastomer engine mount for motor vehicles, having two rubber bodies being at least intermittently connected in series, includes intermittently spanning one of the two series-connected rubber bodies as a function of predetermined operating parameters with rigid components of the mount by means of a separate force brought to bear from the outside. Induced forces are elastically effectively received with only the other of the two rubber bodies. An elastic engine mount, especially for motor vehicles, includes rotationally symmetrical rubber bodies disposed one above the other in series. The first rubber body is fixed between an engine mount plate and a support plate. The second rubber body is fixed between the support plate and a retaining plate to be pivoted at a vehicle body. An annular housing surrounds and partly encompasses the second rubber body. One end surface of the housing is rigidly connected to one of the plates bounding the second rubber body and the other end surface of the housing encompasses the rim of another of the plates with play. A spreading device operates between the one plate and the other plate for bringing those plates plate into contact with the housing and spanning the second rubber body.
