STOPPER PORTION VIBRATION FREQUENCY TUNING METHOD FOR CYLINDRICAL LIQUID SEALED VIBRATION PROOFING MOUNT

摘要

PROBLEM TO BE SOLVED: To solve the problem that noises are generated by resonating a stopper portion of a cylindrical liquid sealed transmission mount, which has the resin stopper portion for restricting excessive relative displacement between a rigid outer cylinder member and an inner cylinder member in the radial direction, to amplify gear noises generated on a transmission side and conveying them into a vehicle room.;SOLUTION: The cylindrical liquid sealed vibration proofing mount 10 has the outer cylinder member 12 and the inner cylinder member 14, a rubber elastic body 16 provided therebetween, a liquid chamber 24, and the resin stopper portion 38. In a method for tuning the vibration frequency of the stopper portion 38 in the longitudinal and turning-down directions of a vehicle, a metal core member 54 having a base end fixed to the inner cylinder member 14 and configured to rise from the inner cylinder member 14 toward the end of a resin body 40 is provided in the state of being embedded in the resin body 40. The core member 54 is used for changing the rigidity of the stopper portion 38 to be more rigid to tune the vibration frequency.;COPYRIGHT: (C)2004,JPO&NCIPI
