Title:
STRUT ARM BUSH AND DOUBLE JOINT TYPE SUSPENSION USING THE SAME
Document Type and Number:
Japanese Patent JP2008128411
Kind Code:
A
Abstract:

To provide a strut arm bush of a new structure, capable of attaining improvement in durability by surely limiting relative displacement of an inner shaft member and an outer cylindrical member in a shaft-orthogonal direction by a stopper mechanism while reducing or avoiding generation of impact at the time of contact with the stopper.

A separate shaft end stopper member 34 is incorporated to either one side of the inner shaft member 12 and the outer cylindrical member 14, and the stopper member includes a shaft end stopper rubber 38 protruding in the axially orthogonal load input direction toward the other side, the stopper rubber 38 being formed in a circumferentially stepped shape by forming a recessed part 42 extending in the shaft direction at a protruding apex part of the stopper rubber 38. At the time of relative displacement in the axially orthogonal load input direction of the inner shaft member 12 and the outer cylindrical member 14, a central stopper rubber 30, both the circumferential side parts of the recessed portion 42 of the stopper rubber 38, and the recessed part 42 of the stopper rubber 38 are brought into contact therewith in series.
