Abstract
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.
Claims17
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.

A vibration absorber for a vehicle comprising:
- a first support arm defining a first aperture;
- a second support arm defining a second aperture;
- a cylindrical mass mounted to the first and second support arms;
- a first and second mounting member seated within the aperture of the first and second support arms respectively, and configured to be mounted to the vehicle;
- and
- a first elastomeric element between the first mounting member and the first support arm;
- a second elastomeric element between the second mounting member and the second support arm;
- wherein movement of the cylindrical mass articulates the first and second elastomeric elements in shear to absorb vibration of the vehicle;
- the cylindrical mass includes only a cylindrical body attached directly to the first and second support arms;
- 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.

A vibration absorber for a vehicle comprising:
- a first support arm including a first bushing assembly configured to be mounted to the vehicle;
- a second support arm including a second bushing assembly configured to be mounted to the vehicle, the first and the second support arms extend generally parallel to one another;
- a cylindrical mass mounted to and extending between the first and the second support arms;
- and
- an elastomeric element included with each one of the first and the second bushing assemblies, movement of the cylindrical mass articulates the elastomeric element of each of the first and the second bushing assemblies in shear to absorb vibration of the vehicle;
- wherein
- the cylindrical mass includes only a cylindrical body attached directly to the first and second support arms;
- and
- the first and the second support arms are configured to support the cylindrical mass at a plurality of different distances from the first and the second bushing assemblies to tune the mass.
