Abstract

A method is disclosed for providing a tuned mass damper for a powertrain component. The method includes the steps of providing a mount adapted to be attached to the powertrain component; assembling a mass element to the mount; and molding an elastomeric body around the mass element to bond the mass element to the mount. The tuned mass damper assembly for a drivetrain component is also disclosed that may be attached to a mount having an opening that extends through the mount or a housing portion provided on the mount The molded elastomeric body integrally attaches the mass element to the mount. Alternatively, the tuned mass assembly may be bonded to a plate that is attached to a motor retention element.

First claim

What is claimed is:

1. A tuned mass damper assembly for a drivetrain component attached to a vehicle frame comprising:
a snubbing plate attached to a mounting plate of the drivetrain component;
a molded elastomeric body; and
a mass element being a solid metal body defining a hole, wherein the mass element is tuned to damp a predetermined vibration, and wherein the molded elastomeric body encases the mass element and fixedly attaches the mass element to the snubbing plate.

2. The tuned mass damper assembly of claim 1 wherein the elastomeric body attaches the mass element to the snubbing plate.

3. The tuned mass damper assembly of claim 1 wherein the drivetrain component is an e-machine, and the mount is a pendulum mount that attaches the e-machine to an over-hanging crossbar attached to the vehicle frame.

4. The tuned mass damper assembly of claim 1 wherein the mount is an engine mount that is attached to the vehicle frame.

5. The tuned mass damper assembly of claim 1 wherein the molded elastomeric body is formed of rubber that encases the mass element.
