Abstract

An engine mount which connects an engine to a vehicle body is provided. The engine mount includes a housing which defines a body of the engine mount and a main rubber body that is installed within the housing and defines a space portion that accommodates a fluid that flows through a nozzle plate. A core is inserted into and fixed to the main rubber body and an a fixing bolt is coupled to the core. A lower support bracket is coupled to the vehicle body and the fixing bolt is inserted therein. A damper that attenuates vibration is disposed at a lower side of the core or at first and second ends of the lower support bracket of the of the engine mount.

First claim

What is claimed is:

1. An engine mount which couples an engine to a vehicle body, comprising:
a housing which defines a body of the engine mount;
a main rubber body installed within the housing and defines a space portion that accommodates a fluid that flows through a nozzle plate;
a core inserted into and fixed to the main rubber body;
a fixing bolt coupled to the core;
a lower support bracket into which the fixing bolt is inserted, wherein the lower support bracket is coupled to the vehicle body; and
a pair of dampers coupled to a first end and a second end of the lower support bracket, respectively,
wherein each of the dampers includes
a base formed in a flat plate shape and penetrated by the fixing bolt;
a washer coupled to an upper side of the base and having an upper plate and a body that extends downward from the upper plate; and
