Title: Low noise decoupler
Inventor: DOUGLAS L POWER
IPC: F16F13/10
Filed: 2017-03-28
Abstract: PROBLEM TO BE SOLVED: To solve a problem that decoupler chortle, which is a problem at mount transients (large displacements) such as engine start-up/shutdown, continues to be a noise and vibration handling (NVH) issue that automotive engineers often struggle with.SOLUTION: A reduced noise decoupler 300' has a perimeter 302' with a wavy form. This provides a significant reduction in initial contact noise. Hydraulic pressure deforms the wavy edges 302', pressing the wavy edge 302' flat and creating necessary seal. The edge geometry is created such that pressure will flatten the perimeter 302' of the decoupler 300' without creasing, ensuring a proper seal without losses. This is achieved by drawing the "wavy" detail from the perimeter 302' to an interior 304' of the decoupler 300' body in alternating fashion to create a pattern of peaks and troughs bounded by thicker sections, allowing the edges to easily deform without creasing.SELECTED DRAWING: Figure 7
