ACTIVE CONTROL ENGINE MOUNT USING A DIRECT FORCE DRIVING MECHANISM WITHOUT FLUID AND AN ELECTROMAGNETIC ACTUATOR

摘要

An active engine mount using a dry-type power transmission mechanism and an electromagnetic actuator is provided to reduce vibration and noise by operating a structure including a ball bearing and a leaf spring without fluid. An active engine mount using a dry-type power transmission mechanism and an electromagnetic actuator comprises a housing including an upper housing(210) and a lower housing(220), a vibration absorption member(230), an electromagnetic actuator(240), a ball bearing(250) and a leaf spring(260). The vibration absorption member is fixed to the housing to support a coupling member(30) on which an engine(20) is installed. The ball bearing comes in contact with a lower end of the coupling member and an upper end of the electromagnetic actuator. The leaf spring connects the coupling member to the electromagnetic actuator such that the coupling member rotates or moves corresponding to vibration of the engine.
