PROBLEM TO BE SOLVED: To provide wholly efficient series engine mounts having novel construction for satisfying mutually different vibration control properties and product prices at high levels as required for every vehicle type by applying themselves to the plurality of vehicle types. SOLUTION: An adopted mount body 10 having novel property construction comprises a pressure receiving chamber 36 to which vibration is input and a variable capacity balancing chamber 38, an intermediate chamber 70 is formed in addition thereto with its wall portion partially constructed by a pressure control rubber plate 44 for controlling pressure fluctuation, the pressure receiving chamber 36 and the balancing chamber 38 being communicated with each other via a first orifice passage 72 subjected to low frequency tuning and the intermediate chamber 70 and the balancing chamber 38 being communicated with each other via a second orifice passage 74 subjected to medium frequency tuning, and a pressure fluctuation transmitting means 56 provided between the pressure receiving chamber 36 and the intermediate chamber 70 for transmitting pressure fluctuation in a restrictive manner. Three types of mutually different additional elements for selective combination are selectively adopted for the mount body 10. Their combination provides selectively constructed engine mounts 100, 200, 300 having mutually different vibration control properties. COPYRIGHT: (C)2005,JPO&NCIPI |
