Tuned vibration absorber

摘要

A vibration absorber for a vehicle. The vibration absorber includes a bushing assembly and a mass. The bushing assembly includes an elastomeric element. The mass is mounted relative to the bushing assembly. Movement of the mass articulates the elastomeric element in shear to absorb vibration of the vehicle.

1. A vibration absorber for a vehicle, the vibration absorber comprising:
a first bushing assembly including a first elastomeric element; a second bushing assembly having a second elastomeric element; a cylindrical mass attached to both the first bushing assembly and the second bushing assembly; wherein movement of the cylindrical mass simultaneously articulates both the first elastomeric element and the second elastomeric element in shear; the cylindrical mass includes only a cylindrical body attached to the first and second bushing assemblies; the first bushing assembly is mounted to a first support arm and the second bushing assembly is mounted to a second support arm; a first end of the cylindrical mass is coupled directly to the first support arm and a second end of the cylindrical mass is coupled directly to the second support arm; the cylindrical mass extends between the first support arm and the second support arm; and the first and the second support arms are configured to couple with the cylindrical mass at a plurality of different locations along respective lengths of the first and second support arms to tune the vibration absorber to absorb a predetermined frequency.
