Abstract
A reinforcing plate (405) is utilized with a lightweight hub (101) in a vibration damper. Holes (105) formed in the hub (101) and the reinforcing plate (405) allow the vibration damper to be mounted to a shaft with a stronger joint than when the reinforcing plate (405) is not utilized, thereby preventing deformation of the hub (101). Optional reduction holes (111) formed in the hub (101) provide for additional weight reduction, vibration reduction, and/or noise reduction.
