Abstract
An exhaust system hanger has a flat serpentine spring encapsulated by an elastomeric block. The spring provides the stiffness to support and retain accelerations. The elastomeric member provides an absorptive member for noise and a dampening means for vibration.
Claims11
A method of hanging an exhaust system including pipes, mufflers, catalytic convertors or the like to a vehicle, the method comprising:
- providing an exhaust system including a pipe, muffler, catalytic convertor, or exhaust component;
- providing a plurality of hangers comprised of flat serpentine spring means which provides a suspension member between mounting points which carries the pipe, muffler, catalytic converter or exhaust component at rest and which resists further accelerations during movement, said serpentine spring means encased by an elastomeric material;
- attaching one end of said hangers to said exhaust system at predetermined position on said exhaust system;
- attaching the other end of said hangers to the underside of the vehicle;
- hanging the exhaust system on the vehicle.

An exhaust hanger comprising:
- a flat serpentine spring means for providing stiffness and a suspension member between mounting points which carries an exhaust component at rest and which resists further accelerations of the exhaust component during movement to the hanger;
- an elastomer cover encasing said flat serpentine spring means for dampening noise and vibration;
- end means on each end of said hanger for enabling securement of said hanger to an exhaust system or to a vehicle under body.
