Title:
CENTER BEARING SUPPORT
Document Type and Number:
WIPO Patent Application WO/2023/120222
Kind Code:
A1
Abstract:
The present invention realizes a center bearing support which is suitable for suppressing a decrease in vibration absorption performance in a high frequency region. The present invention comprises a cylindrical outer ring 3 that is attached to a vehicle-body-side member in a state where an outer peripheral surface 3b is in contact with the member; a cylindrical inner ring 2 that is attached to a center bearing in a state where an inner peripheral surface 2b is in contact with the outer periphery of the center bearing; an elastic body 1 that extends in a manner forming a bellows-like curved shape which connects the inner peripheral surface 3a of the outer ring 3 and the outer peripheral surface 2a of the inner ring 2 and which, between said surfaces, protrudes in one direction along a propeller shaft. The elastic body 1 has a curved plate-like base part 15 that, between the inner peripheral surface 3a of the outer ring 3 and the outer peripheral surface 2a of the inner ring 2, maintains a constant thickness while extending in a manner to form a bellows-like curved shape, and a protrusion part 14 that is laminated on a protruding surface 11a of a curved part of the base part 15 and that protrudes in one direction. The base part 15 and the protrusion part 14 are integrally formed from an elastic material.
