Vibration isolator

摘要

A vibration isolator includes: a pair of opposing members fixed to a vehicle body of the vehicle to be located on both sides of a protrusion protruding from an outer circumferential edge of the power train in a direction perpendicular to the principal axes of inertia to oppose to each other in the direction about the principal axes of inertia; a precompressed part provided on part of each of the opposing members facing the protrusion to be precompressed by the opposing member and the protrusion in the direction about the principal axes of inertia; and a contacting part provided on part of each of the opposing members facing the protrusion to be spaced from the protrusion, and contacts the protrusion when the power train vibrates in the direction about the principal axes of inertia.

1. A vibration isolator configured to reduce vibration of a power train mounted on a vehicle in a direction about principal axes of inertia of the power train, the vibration isolator comprising:
a pair of opposing members fixed to a vehicle body of the vehicle to be located on both sides of a protrusion in the direction about the principal axes of inertia, the protrusion protruding from an outer circumferential edge of the power train in a direction perpendicular to the principal axes of inertia, so that the opposing members oppose to each other in the direction about the principal axes of inertia; a precompressed part provided on part of each of the opposing members facing the protrusion to be precompressed by the opposing member and the protrusion in the direction about the principal axes of inertia; and a contacting part provided on the part of each of the opposing members facing the protrusion to be spaced from the protrusion, and contacts the protrusion when the power train vibrates in the direction about the principal axes of inertia, wherein the precompressed part and the contacting part are provided on each of the opposing surfaces of the opposing members.
