<P>PROBLEM TO BE SOLVED: To provide a control type engine mount in which both of liquid pressure in a liquid chamber generated by a support elastic member and vibration control performance of the support elastic member are satisfied. <P>SOLUTION: The control type engine mount includes: an engine side attachment part 11; an elastic body 13 that is connected to the engine side attachment part 11; a liquid chamber 19 formed in the elastic body 13; a liquid pressure control device 20 that controls liquid pressure in the liquid chamber 19; and an engine mount body 14 that is connected to the elastic body 13 and is attached to a vehicle body. The pressure control device 20 includes a vibration plate 22 that blocks the liquid chamber 19, an elastic membrane 23 that supports the vibration plate 22 to the elastic body 13, and a driving mechanism 24 that drives the vibration plate 22. The elastic membrane 23 includes a plurality of reinforcing parts that are formed from the center of the vibration plate 22 toward the surrounding, and extension parts each of which is formed between the reinforcing parts and suppresses the rising of pressure in the liquid chamber 19 to a prescribed pressure or more. <P>COPYRIGHT: (C)2012,JPO&INPIT |
