Anti-vibration device for vehicle

摘要

An anti-vibration device for a vehicle including a rod (11) fixed to an engine (1) at one end portion (12) thereof and fixed to a vehicle body at the other end portion (13) thereof, an inertia mass (15) supported on the rod (11), an actuator (17) operative to reciprocate the inertia mass in an axial direction of the rod, and an acceleration sensor (21) that detects vibration of the rod in the axial direction. The acceleration sensor (21) is disposed between the one end portion (12) of the rod (11) and the other end portion (13) of the rod (11). Accordingly, sensitivity to pitch vibration of the rod (11) is reduced so that accuracy in detection of rigid body resonance in the axial direction is enhanced.

1. An anti-vibration device for a vehicle, comprising:
a rod fixed to an engine at one end portion thereof and fixed to a vehicle body at the other end portion thereof; an actuator comprising an inertia mass supported on the rod and operative to reciprocate the inertia mass in an axial direction of the rod; and a vibration detection section configured to detect vibration of the rod in the axial direction of the rod, wherein the vibration detection section is disposed between the one end portion of the rod and the other end portion of the rod, and is disposed on a side of the rod opposite to a side of the rod facing the engine in a leftward-rightward direction of the vehicle.
