Title:
MULTI-STAGE DAMPING ASSEMBLY
Document Type and Number:
Japanese Patent JP2017223366
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a damping assembly with increased tuning.SOLUTION: An assembly for multi-stage damping comprises a damping unit 20 including a decoupler 36 defining an annular zone 70 surrounding a circular zone 68. The annular zone 70 extends inwardly from an outer ring 38 to define a ring shape for flexing with the circular zone 68 in a first mode 72 to maximize the potential volume of displacement between a first chamber 30 and a second chamber 32. Additionally, the assembly provides for flexing the annular zone 70 independently of the circular zone 68 in a second mode 74 to decrease the potential volume of displacement of the decoupler 36 between the first chamber 30 and the second chamber 32. The decoupler 36 includes a plurality of rings 38, 46, 54 extending axially from a first surface 40 and a second surface 42 for defining an axial travel limit for the annular zone 70.SELECTED DRAWING: Figure 1
