Abstract

The present invention provides an operating sound cancelling apparatus for a semi-active engine mount of a vehicle, in a structure of a solenoid valve for opening and closing an air chamber of the semi-active engine mount, an upper stopper is formed in a plurality of layers, thereby not only improving airtightness and durability of the upper stopper, but also improving reliability of the upper stopper. And the noise can be reduced while the impact generated when the upper check block collides with the valve shell can be absorbed.

Description

technical field [0001] The present invention relates to an operation noise cancelling device for a semi-active engine mount for a vehicle, and more particularly, to a semi-active engine for a vehicle capable of canceling the operation noise generated when an actuator of the semi-active mount is operated Operation sound cancelling device for stand. Background technique [0002] Generally, when a power train of a vehicle including an engine and a transmission is installed in an engine room, an engine bracket is used to install the power train to effectively reduce engine vibration and noise transmitted to the vehicle body. [0003] Typically, the engine mounts support the driveline in the engine compartment of the vehicle, serve to isolate vibrations generated by the driveline when idling, and control the behavior of the driveline while driving. [0004] The engine mounts include fluid mounts sealed with fluid, vacuum negative pressure semi-active mounts, electronic semi-acti...
