Title:
TORQUE ROD
Document Type and Number:
Japanese Patent JP2019196791
Kind Code:
A
Abstract:
To surely transmit thrust necessary for attenuating and absorbing low-frequency vibration to an inner cylinder of either of a first elastic bush and a second elastic bush.SOLUTION: A torque rod 1 comprises: a first elastic bush 11 having an inner cylinder 11a connected to either of a vibration generation part and a vibration receiving part; a second elastic bush 12 having an inner cylinder 12a connected to the other; and an actuator 14 arranged between the first elastic bush and the second elastic bush, and attenuating and absorbing input vibration by exciting a movable body 13 according to the input vibration. The movable body comprises an abutment piece 15 abutting on the inner cylinder of either of the first elastic bush and the second elastic bush, and attenuates and absorbs the input vibration by exciting the abutment piece according to the input vibration. The abutment piece is arranged on a movable axial line O3 orthogonal to a center axial line of one inner cylinder, and passing the center of gravity of the torque rod.SELECTED DRAWING: Figure 1
