ASSEMBLY FOR REDUCING AUTOMOTIVE NOISE AND VIBRATION

摘要

The invention provides an assembly for use in reducing automotive noise and vibration transmitted from a road surface through the vehicle tire and axle system. The assembly of the invention comprises a spring seat retainer comprising (a) first and second oppositely directed surfaces, (b) a recessed area in the first surface, and (c) an axially directed interior cavity. A spring isolator having at least a portion of one surface coexistent with a portion of the second surface of the spring seat retainer is attached to the spring seat retainer. A jounce bumper having an exterior surface is positioned within the interior cavity of the spring seat retainer such that a portion of the exterior surface of the jounce bumper is coexistent with the inner surface of the interior cavity of the spring seat retainer. A coil spring is releasably connected to the spring seat retainer via a bottom most section retained within a recessed area of the spring seat retainer. The coil spring surrounds the jounce bumper. The invention provides advantages in cost and efficiencies as well as increased durability and long term performance due to the elimination of component interactions vulnerable to the point load degradation.
