<p><P>PROBLEM TO BE SOLVED: To provide a pendulum engine support structure capable of simultaneously suppressing a steady idle vibration, a low-order idle vibration, and a vibration due to an engine shake. <P>SOLUTION: In an engine mount 4, a partition member 15 is provided inside a cylindrical member 12 of the outer side axially of a center member 11. Each chamber formed by circumferentially dividing a chamber surrounded by a second rubber member 14, the partition member 15, and the cylindrical member 12, and a space surrounded by a first rubber member 13, a second rubber member 14, a center member 11, and the cylindrical member 12 into two parts is filled with liquid, so that a first main liquid chamber 21, a pair of second main liquid chambers 22A, and the other are formed respectively. An auxiliary liquid chamber 24 is so provided as to change in volume with an inside liquid pressure. The first main liquid chamber 21 is allowed to communicate with the auxiliary liquid chamber 24 through a first orifice 31. A pair of second main liquid chambers 22A and the other are allowed to communicate with the auxiliary liquid chamber 24 through a pair of second orifices 32A and the other provided corresponding thereto respectively. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
