Abstract
An electromagnetic active engine mount includes a main body having a chamber in which non-compressive fluid is encapsulated, and an anti-vibration rubber installed at an upper portion thereof, and an electromagnetic driver having a vibrating unit for generating vibration when vibration is transmitted from an engine, and a solenoid installed at a lower portion of the vibrating unit in order to control the vibration of the vibrating unit.
Claims19
An active engine mount comprising:
- a main body including a chamber defined by an elastic member to receive a fluid therein;
- an actuating unit;
- a vibrating unit fluidly isolating the actuating unit from the chamber and vibrated by the actuating unit for vibrating the fluid in the chamber, wherein the actuating unit is enclosed by a support housing and the vibrating unit;
- a driver housing and a bottom housing configured to enclose the support housing with a predetermined gap to form a channel and an auxiliary chamber therebetween;
- and
- at least a fluid passage formed between the chamber and the channel so as to communicate between the chamber and the channel.

An active engine mount comprising:
- a main body having a chamber, in which non-compressive fluid is encapsulated, and an anti-vibration rubber installed at an upper portion thereof;
- and
- an electromagnetic driver having a vibrating unit for generating a vibration when a vibration is transmitted to the active engine mount from an engine, and a solenoid to activate the vibrating unit installed at a lower portion of the vibrating unit in order to control the vibration of the vibrating unit,
- wherein the solenoid includes a coil connected with a controller to establish a magnetic field and a yoke formed around the coil to enable the coil to establish the magnetic field, wherein the yoke is integrally formed with the coil by injection molding so as to minimize a gap from the coil.
