Electronic active suspension capable of bi-directional control

Abstract

An electronic active mount capable of bidirectional control. The invention relates to an engine mount, more particularly, to an electronic active mount capable of bidirectional control, comprising: a core, a main rubber part, an upper orifice plate, a lower orifice plate, a lower casing, and a partition plate , the core is located within a casing having a cylindrical shape and is connected to the engine; the main rubber piece is configured to connect the outer surface of the core and the inner surface of the casing; the upper orifice plate is coupled to the end of the main rubber piece so as to form an upper fluid chamber capable of accommodating fluid, and having a central portion with which the membrane is coupled to move in upward and downward directions; the lower orifice plate is connected to a lower end of the upper orifice plate; the lower case is formed at the central portion of the lower orifice plate the spacer at a predetermined distance from the lower orifice plate so as to form a lower fluid chamber capable of containing fluids which can be transmitted in both directions by using two electromagnets arranged in the electronic suspension Vibration damping and appropriate response to vibration.

Problems solved by technology

[0015] However, since the additional permanent magnet is made of rare earth material, its supply and demand are unstable, its cost is high and its weight is heavy

Therefore, the use of permanent magnets is problematic
