CYLINDRICAL VIBRATION-ISOLATING MOUNT AND POWER PLANT SUPPORT DEVICE USING THE SAME MOUNT, AND CONTROL METHOD OF CYLINDRICAL VIBRATION-ISOLATING MOUNT FOR THE POWER PLANT SUPPORT DEVICE

摘要

PURPOSE: To provide a power plant supporting device with which active control of vibration is enabled and, by using it for car engine mount, a superior vibration-isolating effect can be obtained against vibration in the vertical direction and also idling vibration around a torque roll axis. ;CONSTITUTION: A pair of electrostriction elements (46, 48) which give a drive force roughly in radial directions different from each other are positioned between inner and outer cylindrical metal fittings 12 and 14 connected to each other with a rubber elastic body in parallel with each other. Using a cylindrical vibration-isolating mount 10 with which independent power supply to the electrostriction elements is enabled, a pair of electrostriction elements 46 and 48 on the cylindrical vibration-isolating mount are installed between a power plant and a supporting member so that they are positioned on both sides of a vertical plane including torque roll axis of the power plant.;COPYRIGHT: (C)1993,JPO&Japio
