Abstract

A fluid-sealed engine mounting has a connector adapted to be connected to an engine, a base adapted to be connected to a vehicle frame, an elastic member joined between the connector and the base and elastically deformable in response to vibrations transmitted thereto, the connector, the base, and the elastic member jointly defining a fluid chamber in which a fluid is sealed, and a partition dividing the fluid member into a first chamber adjacent to the connector and a second chamber adjacent to the base, the partition having an orifice through which the first and second chambers communicate with each other. The engine mounting also includes a diaphragm mounted on the base or the connector for varying the volume of one of the first and second chambers when vibrations are transmitted to the engine mounting.

Dependent claims

A fluid-sealed engine mounting for mounting an engine on a vehicle frame, comprising:

(a) a connector adapted to be connected to the engine;
(b) a base adapted to be connected to the vehicle frame;
(c) an elastic member joined between said connector and said base and elastically deformable in response to vibrations transmitted thereto, said connector, said base and said elastic member jointly defining a fluid chamber in which a fluid is sealed;
(d) a partition being entirely disposed intermediate said connector and said base and dividing said fluid chamber into a first chamber adjacent to said connector and a second chamber adjacent to said base, said partition having an orifice through which said first and said second chambers communicate with each other;
and
(e) a diaphragm mounted on one of said connector or said base for varying the volume of one of said first and second chambers when vibrations are transmitted to the engine mounting, said base comprises a frustoconical tubular body mounted on an end of said elastic member and having a radially outwardly projecting flange on the end thereof closer to said connector, said flange including means for attachment to the vehicle frame.
