Abstract

A damper for a steering wheel is provided. The damper may include a housing attached to the steering wheel and an energy-storage medium supported by the housing.

Claims

1. A steering wheel comprising:

a rim;

a hub attached to said rim; and

a mass damper supported proximate to said hub and including a housing and a source of power, said source of power including an electrical energy storage medium, said housing being coupled to said hub by a spring or spring-like material for movement relative to said hub, said electrical energy storage medium being supported by said housing, said housing and said electrical energy storage medium cooperating to provide said mass damper with a desired weight.

2. The steering wheel of claim 1, wherein said housing includes an internal cavity receiving said source of power.

3. The steering wheel of claim 1, wherein said electrical energy storage medium is one of a battery and a capacitor.

4. The steering wheel of claim 1, further comprising a controller supported by said housing and operable to control at least one of said source of power and a system of the steering wheel.

5. The steering wheel of claim 4, wherein said system is at least one of a temperature-control system, a horn, and a light and selectively receives voltage from said source of power.

6. The steering wheel of claim 4, wherein said controller stores operating parameters of said system.

7. The steering wheel of claim 1, wherein the spring or spring-like material is an elastomeric material disposed between said housing and said hub and supporting said housing for movement relative to said hub.

8. The steering wheel of claim 7, further comprising a bracket coupling said elastomeric material to said hub.

9. The steering wheel of claim 8, wherein one of said housing, said bracket, and said hub includes an electromagnet selectively receiving current to alter a magnetic field between said housing and said bracket to adjust a frequency response of said mass damper.

10. The steering wheel of claim 1, wherein said electrical energy storage medium is configured to supply electrical power to a subsystem supported by the steering wheel.

11. The steering wheel of claim 10, wherein said subsystem is at least one of a horn, a light, and a temperature control system to control a temperature of the steering wheel.

12. The steering wheel of claim 4, wherein said controller includes a memory and a processor.

13. The steering wheel of claim 1, wherein said electrical energy storage medium is disposed within said housing and is offset from a rotational axis of the steering wheel.

14. The steering wheel of claim 1, wherein said mass damper is supported for rotation with said hub about a rotational axis of the steering wheel.
