Title:
Vibration control equipment
Document Type and Number:
Japanese Patent JP6045257
Kind Code:
B2
Abstract:
There is provided a device for controlling a resonance frequency of rigid body resonance due to vibration in the axial direction. A large ring part 13 of a torque rod 10 includes an outer frame section 20, an inner member 21, an intermediate ring 22 and an elastic vibration isolating main body 23. The outer frame section 20 and the intermediate ring 22 are integrally combined with the elastic vibration isolating main body 23. An inner clearance 36 is provided between the intermediate ring 22 and the inner member 21 such as to surround the circumference of the inner member 21. The intermediate ring 22 is movable relative to the inner member 21 in the axial direction. With respect to the vibration in the direction of a mounting shaft, the outer frame section 20, the intermediate ring 22 and the elastic vibration isolating main body 23 move together in the axial direction in relation to the inner member 21, whereby the spring in the direction of the mounting shaft (the direction of C3) is weakened and the resonance frequency of the rigid body resonance in the direction of the mounting shaft is decreased.
