Abstract
An electronic active mount capable of a bidirectional control includes a core positioned inside a housing and connected to an engine. A main rubber is configured to connect the core and the housing. An upper orifice is coupled to an end of the main rubber to form an upper fluid chamber. A membrane is coupled to be moved up and down is connected to a lower orifice. A lower housing is formed at a central portion of the lower orifice, and a diaphragm is spaced apart from the lower orifice at a predetermined distance, which may attenuate vibration by using two electromagnets provided in an electronic mount.
Claims4
An electronic active mount capable of a bidirectional control, comprising:
- a core disposed inside a housing having a cylindrical shape and connected to an engine;
- a main rubber connected an outer surface of the core and an inner surface of the housing;
- an upper orifice coupled to an end of the main rubber so as to form an upper fluid chamber capable of accommodating a fluid, and having a central portion to which a membrane is coupled to be moved in an up and down direction;
- a lower orifice connected to a lower end of the upper orifice;
- a lower housing formed at a central portion of the lower orifice;
- and
- a diaphragm spaced apart from the lower orifice at a predetermined distance to form a lower fluid chamber capable of accommodating a fluid,
- wherein an upper bobbin and upper electromagnet enclosing the upper bobbin are included in the membrane, and a lower bobbin and a lower electromagnet enclosing the lower bobbin are included in the lower housing.
